如何筛查和预防大肠腺瘤性息肉？

【摘要】由于存在多种致病因素，大肠腺瘤性息肉经肠镜摘除术后容易复发，特别是多发性腺瘤患者。临床上筛查和预防大肠腺瘤性息肉复发的方法有以下几种: ①定期肠镜检查；②主动避免高危因素；③大便隐血试验；④大肠腺瘤风险评分；⑤中医药干预。每一种方法各有优缺点，不同患者根据自己的情况，选择合适自己的方法进行筛查预防。如发现有大肠腺瘤，建议摘除腺瘤后中药干预1－2个月。

【关键词】大肠腺瘤性息肉，风险评分，中药治疗，预防复发

正文

研究认为诱发腺瘤性息肉与结直肠癌发病的危险因素基本一致。腺瘤性息肉发病有多种相关的危险因素。肠镜摘除术后复发的诱发因素没有祛除，因此肠道粘膜病变会一直持续进行。每年或每二年的定期复查肠镜，由于多种原因，多数人难以坚持下去。临床很多因素影响了复查的间隔时间。如果有一种简便评估方法，达到一定的标准即可建议暂缓不做（或者推荐立即预约肠镜检查），一定受广大肠息肉（腺瘤）患者的欢迎。同时，根据这种评估方法，可以有针对性地进行预防。

1、定期肠镜检查

一般而言，一次肠镜检查能确保4－5年大肠的安全。大肠多发腺瘤（含息肉，下同）术后第一年复发率在40%，第五年复发率可达80%以上。医院的等级、医生的职称、年龄、医生手术的状态均有可能增加一次肠镜检查腺瘤的漏诊率。如果同时导致患者大腺瘤增生的影响因素没有排除明显，大肠腺瘤内镜下摘除术后复发的可能性就非常高。大部分人不可能频繁每年做肠镜检查，特别是很多老年人合并糖尿病，高血压，心脏病，慢性支气管炎等老年病。因此定期肠镜检查只适合很少一部分人群，对大部分人群来说，有必要用一些简便的方法进行预防筛查，避免频繁肠镜检查，有比较简单的手段和指标来减少和延长复查间隔时间。

2、主动避免高危因素

近二三十年来，国内外相关的学术和专业人员，对大肠癌的危险因素进行了广泛的、多角度、多领域的研究，普遍认为长期食用腌制品，炎症性肠病、肿瘤家族史（特别是肠癌家族史）和大肠腺瘤家族史、胃息肉和胃幽门螺杆菌阳性、胆囊和阑尾切除术等等，均能导致大肠腺瘤和肠癌的发生和加重。研究还认为，长期的粗膳食纤维的摄入、每日进食水果、坚持体育锻炼等有助于肠腺瘤和肠癌的预防。根据上述情况，我们可以有意识地减少上述危险因素，增加预防作用的因素，自己主动进行预防。缺点:有些因素是客观事实，没法改变，比如阑尾切除术，胆囊切除术、肿瘤家族史。这些因素是无法避免的，只能从其他因素加以考虑。综述所述，主动避免高危因素效果很有限，且难以常年持续，很多因素明难以避免。

3、大便隐血试验

大便隐血试验是最近简单经济的筛查手段。缺点是阳性率较低，只有10-20%左右。存在假阳性，假阳性高达80%以上。而且很多肠腺瘤患者并无便血症状。漏诊率也很高，大腺腺瘤患者并不是每天都在出血。因此，患者肉眼见便血，大部分人不是肠息肉或腺瘤出血。大便隐血检查也需要到医院挂号缴费等，也非常耗费时间，至少半天时间。很多人嫌费时不愿持续进行。由于上述因素，很多患者不重视这个检查项目。有文献报道认为每年坚持粪便隐血试验检查，10－15年后可以降低30%左右的腺瘤癌变。

4、大肠腺瘤性息肉风险评估

这种方法最简单实用，适合绝大部分人群。微信扫码就可以方便快速地进行自我测试，也可以居家为家人慢慢测试。结果自动显示，非常方便和接地气。这种方法尤其适合没有症状或者轻微症状的人群。对有明显症状的人群，比如近期便血，腹痛，腹泻，发热明显的人群，应该及时前往医院检查。最新的版本，对高分人群（＞7分）预测大肠腺瘤（含息肉、肠癌）的准确率达到70－75%。如果对本方法感兴趣的，也可以请医生指导下进行问卷填写，结果应该相对更准确一些。如想详细了解评分结果含义，那就需要咨询专业医生。可以在京东医生上搜刘利华主任医师，进行线上风险评估和专业咨询。本方法的不足之处在于评分表未经大数据验证，准确率和可靠性有待提高。

5、中医药干预

中医理论提倡治未病，即未病先防，既病防变。这种治疗防治思维特别适合大肠癌的早期预防干预。因为肠息肉到癌变需要6－10年的演变过程，有足够时间进行检查预防和干预治疗。受各种因素的长期影响，肠息肉演变成上皮内瘤变。而在肠镜摘除腺瘤术后，这些致病因素并没有祛除。在中医认为，这就是脏腑阴阳气血失调的表现。通过中医调理阴阳失衡，纠正气血不足，达到阴平阳秘的最佳状态。大多数肠腺瘤患者，有明显的阴阳失衡，气血紊乱，水火失调，这时候用中医来调理干预，效果应该会很好。对多数患者而言，中医调理只需要1、2个月就基本可以了。中医认为肠腺瘤的基本病理为脾肾虚亏，气血不足，兼夹湿毒瘀。脾肾两虚是决定结直肠腺瘤性息肉复发的最主要因素，贯穿于结直肠腺瘤发展的始终。有作者提出基于结直肠腺瘤性息肉的病因病机，选择以健脾扶正为主、燥湿化瘀为辅的中医治疗方案，尤其是对于先天不足、素体虚弱及术后气血亏虚、正虚邪恋者，可以起到明显的疗效，缓解和减少其癌变程度或速度。健脾祛湿、活血解毒中药可通过 Wnt /β － catenin 信号通路抑制肿瘤细胞的生长或转移，起到抗肿瘤作用。陈氏观察到健脾理肠汤可有效改善患者临床症状，降低腺瘤性大肠息肉术后复发率。健脾化瘀汤可降低大肠腺瘤切除术后的复发率，其作用机制可能与下调 COX-2、Ki67 表达有关。

综合文献报道，中药干预大肠腺瘤摘除术后的复发疗效，可以减少50-70%以上的瘤性息肉复发。这对于单发或多发腺瘤患者来说非常满意了。一般人群可以采取以下思路进行大肠腺瘤的早期筛查和预防。首先选择前面五种方法的1－2种，如提示为大肠腺瘤高风险人群，选择肠镜检查，如发现有大肠腺瘤，内镜下进行摘除术，术后用中药干预1－2个月，预防腺瘤术后复发。有肠道症状者建议适当延长用药时间。

大肠腺瘤西医治疗方法是什么

大肠腺瘤是一个什么样的疾病我们大家并不清楚，对于这样的疾病我们很多的人都想要去了解，对于一个陌生的疾病我们只有了解更多我们的心里才会有底，所以很多的人都迫切的想要知道大肠腺瘤西医治疗方法是什么?

大肠腺瘤属癌前病变，一经发现均应及时处理。多数腺瘤可通过镜下切除，肠镜无法切除时(多数为直径大于2cm的绒毛状广基腺瘤)则应手术切除。对于术后病检无癌变者无须进一步治疗;有癌变者应根据浸润深度选择不同的治疗方式。

1.镜下切除镜下切除的方法有圈套凝切法、活检钳凝切法、电凝器灼除法等。对于有蒂型腺瘤可行圈套切除，对于小于0.5cm的广基型腺瘤可采用活检钳凝切法或电凝器灼除法，0.5～1cm的广基型可采用圈套凝切法进行切除。

2.手术切除对于直径大于2cm的绒毛状广基腺瘤不宜经肠镜分块切除，而应采用手术切除，一般按大肠癌手术处理原则进行。

3.腺瘤癌变的处理

(1)癌局限于黏膜层者，采用局部切除术，术后肠镜随访。

(2)癌变侵入黏膜下层而未达固有肌层者，我国通常根据腺瘤病理类型决定手术方式。

①管状腺瘤：如果切缘无癌，或切片中无血管和淋巴管受累，或癌细胞分化好，或病理学检查证实腺瘤完全切除，一般只需局部切除加密切随访即可。

②绒毛状腺瘤：由于其淋巴结转移的可能性高达29%～44%，因此应按通常的大肠癌作包括淋巴结清除的肠切除术。

③混合性腺瘤：如为有蒂型，其处理原则与管状腺瘤癌变限于黏膜下层时相同，如为广基型，则与绒毛状腺瘤癌变限于黏膜下层时的处理原则相同。

(3)腺瘤癌变浸润至肌层者，行根治性肠切除术。

以上就是关于大肠腺瘤西医治疗方法是什么的介绍，我们在生活中已经很了解西医了，有的人认为中医好有的人认为是西医好，很多的人都不知道这两个每个都有自己的好处，所以治疗疾病最好是中西医结合。

大肠忧瘤食疗及导引康复治疗

大肠肿瘤及癌证的发病原因为忧思内疚使肺魄失于宽展而导致阳明血气循结于大肠，长期不解而发生。肺主忧魄，其动为振，其作为裂，其主秋季气象雾露，肺魄失于宽展颜乐则振动不可开拓无能。中医名为大肠忧瘤，其忧自外来气结为肿，忧自内生血结为瘤，内忧外患卫气营魄热结为癌。

大肠忧瘤的上述病理以简明白话俗语比喻即是“肛忧柴火”魄气忧郁寒热下变如同人们事业缺乏新的开拓而在囿居旧循之中“薪水不足”的生活情况。

大肠忧瘤健康愈复食疗宜用羊肉、苦瓜、菜瓜、蒜苗、山药、麦粒蒸厨多食用蔬菜，少量食用生鲜蔬菜。

健康导引宜用健身舞、健身操、五禽戏、十二生肖健身戏、咏春拳的坚持不懈锻炼。勤备柴薪，使用竹椅草席以及勤劳自新洁净俭省储备的生活习惯形成为特点的自我愈复活动及个人明新起居修养。

关于腺瘤

腺瘤是常见的一种良性肿瘤，可以发生于甲状腺的腺体之内或者是发生于肠道，主要病人也会出现疼痛或者是肠道的刺激症状，包括腹胀，甚至也会出现排便异常或者排便带血的表现。

良性病变通常不严重，但是确实之后，也应该进行医学治疗。对于发生于甲状腺腺体内的腺瘤，可以选择局部麻醉下进行手术切除。

而发生于肠道的病变，如果是单纯比较小的腺瘤，可以经结肠镜下进行切除或者活检；肿瘤比较大，如果活检提示是癌，不适合进行镜下切除，可以选择传统的开放手术，或者是腹腔镜下的肠管部分切除手术，并且术后也需要配合抗癌治疗。

而腺瘤是非常常见的一种良性疾病，相对不严重，所以确诊之后也不要过分的担心，只要及时有效治疗，还是比较满意的。

案件31-2023：一名79岁男性，身体不自主运动、一过性反应迟钝

以下内容来源于新英格兰医学杂志。

Presentation of Case

Dr. Carrie Chui (Neurology): A 79-year-old man was admitted to this hospital because of involuntary movements on the left side and transient unresponsiveness.

The patient had been in his usual state of health until 9 months before admission, when involuntary movements of the left shoulder and left side of the face developed. The movements were described by the patient as twitching, were not associated with a change in the level of consciousness, and resolved after 1 to 2 minutes. During the next 6 months, the patient had similar episodes approximately once per month, but the episodes increased in duration, lasting 5 to 6 minutes.

Three months before admission, the episodes of involuntary movements increased in frequency, and the patient was evaluated by his primary care physician. The physical examination was normal. Results of kidney-function tests were normal, as were blood levels of glucose and electrolytes, except for the sodium level, which was 129 mmol per liter (reference range, 135 to 145). There was a history of inappropriate antidiuretic hormone secretion, and the sodium level was similar to levels obtained during the past 4 years. Magnetic resonance imaging (MRI) of the head (Figure 1A), performed before and after the administration of intravenous contrast material, revealed a focus of enhancement in the right middle frontal gyrus that was thought to be a small vascular anomaly. Electroencephalography (EEG), performed with the patient in awake and drowsy states, revealed rare, brief, focal slowing in the left temporal lobe during drowsiness; no epileptiform abnormalities were present.

Two months before admission, the patient was evaluated in the epilepsy clinic affiliated with this hospital. He reported that the episodes of involuntary movements had increased in both frequency and duration, occurring once or twice per day and lasting approximately 10 minutes. Episodes began with tingling and numbness in the left leg that prompted the patient to voluntarily stomp the left foot to relieve the uncomfortable sensation. Then, the patient had involuntary movements that he described as an uncontrollable invisible force moving the left leg and arm, with hyperextension of the arm backward and pronation of the wrist. There was associated numbness in the distal portions of the left third, fourth, and fifth fingers and involuntary movement of the left cheek. No prodromal symptoms occurred. The patient had awareness during the episodes, and after the episodes, he felt fatigued but had a normal level of consciousness, without confusion. The examination in the epilepsy clinic was normal. A diagnosis of seizure disorder was considered, and treatment with levetiracetam was started.

Three weeks before admission, the patient was again evaluated in the epilepsy clinic. He reported that the episodes of involuntary movements still occurred on a daily basis but had decreased in duration and involved only the left leg, without abnormal movements of the arm or face. Dizziness, headache, and weakness had developed and were attributed to the use of levetiracetam. The patient’s family had recorded a video of one of the episodes of involuntary movements. After reviewing the video, the patient’s neurologist thought that the episodes were less likely to be caused by seizures and more consistent with choreoathetoid movements. Cross-tapering of medications — with the simultaneous administration of levetiracetam in decreasing doses and clobazam in increasing doses — was initiated, and the patient was referred to the movement disorders clinic affiliated with this hospital.

On the morning of admission, an episode of involuntary movements of the left leg and left shoulder occurred and persisted for 1 hour. Several hours after the symptoms abated, the patient’s wife found the patient to be unresponsive; he was sitting in a chair. Emergency medical services were called, and when they arrived, the patient was responsive. The fingerstick blood glucose level was 180 mg per deciliter (10.0 mmol per liter) and the blood pressure 110/80 mm Hg. The patient was transported to the emergency department of this hospital for further evaluation.

In the emergency department, the patient reported dysuria and increased urinary frequency. The patient’s daughter noted that he had been more anxious during the past 3 years and occasionally had trouble with memory. Other medical history included Barrett’s esophagus, benign prostatic hypertrophy, chronic hepatitis B virus infection, eczema, gastroesophageal reflux disease, hypertension, nonischemic cardiomyopathy, and osteoporosis. There was no history of head trauma or extended loss of consciousness. Medications included aspirin, atorvastatin, doxazosin, finasteride, omeprazole, metoprolol, sacubitril, and valsartan. There were no known drug allergies. The patient was a lifelong nonsmoker and drank alcohol rarely; he did not use illicit drugs. His mother had had gastric cancer, and his sister had had esophageal cancer; there was no family history of seizures.

On examination, the temporal temperature was 36.8°C, the blood pressure 152/97 mm Hg, the pulse 65 beats per minute, the respiratory rate 16 breaths per minute, and the oxygen saturation 96% while the patient was breathing ambient air. The body-mass index (the weight in kilograms divided by the square of the height in meters) was 21.7. The blood pressure decreased to 130/63 mm Hg with standing. The patient was alert and interactive. The lower jaw was held to the left, but the nasolabial folds and smile were symmetric with activation. There were nonrhythmic, nonstereotyped, writhing movements of the left arm. Tone was normal, and strength was assessed as 5 out of 5 in the arms and legs. Results of liver-function and kidney-function tests were normal, as were blood levels of glucose and electrolytes, except for the sodium level, which was 125 mmol per liter. The lactate level was 2.1 mmol per liter (19 mg per deciliter; reference range, 0.5 to 2.0 mmol per liter [5 to 18 mg per deciliter]). The urinalysis was normal. Intravenous fluids were administered. Imaging studies were obtained.

Dr. Rajiv Gupta: Computed tomographic (CT) angiography of the head and neck (Figure 1B) revealed extensively calcified plaque with severe stenosis of the distal right common carotid artery (CCA), extending into the proximal right internal carotid artery (ICA), as well as stenosis of the right and left paraclinoid ICAs and the left vertebral artery at its origin. There was no vascular abnormality on the CT angiogram that corresponded to the abnormality in the right middle frontal gyrus seen on the previous MRI.

Dr. Chui: The patient was admitted to the hospital. On the second hospital day, the sodium level had increased to 130 mmol per liter, and the lactate level was normal. Additional imaging studies were obtained.

Dr. Gupta: MRI of the head showed no evidence of acute infarction. The focus of enhancement in the right frontal lobe that had been noted previously was not seen on the current MRI.

Dr. Chui: Blood levels of thyrotropin, cobalamin, and glycated hemoglobin and results of coagulation tests were normal. Screening tests for Lyme disease, tuberculosis, and syphilis were negative, as were tests for antibodies to cardiolipin and β₂-glycoprotein. A test for antinuclear antibodies was positive, at a titer of 1:160 in a homogeneous pattern. During a physical therapy session, the patient had abnormal movements of the left leg, left arm, and left side of the face. The abnormal movements diminished when the patient used distraction techniques, such as thigh tapping, finger snapping, and walking while holding a glass of water.

The transient unresponsiveness that led to the patient’s admission was attributed to a combination of sedation from clobazam and hypovolemia. Treatment with clobazam was stopped, and hydration was encouraged. A diagnosis of functional neurologic disorder was considered; outpatient physical therapy with continued use of distraction techniques was recommended. The patient was discharged home on the third hospital day.

Episodes of involuntary movements continued to occur on a daily basis at home. Two weeks after discharge, when the patient was doing exercises while sitting in a chair and having a conversation with his wife, he suddenly stopped talking. She found him slumped in the chair with his eyes closed, no longer exercising. When she asked him questions, he repeatedly said “yes.” Emergency medical services were called, and when they arrived, the patient was alert, diaphoretic, and nonverbal. He had a facial droop on the left side and a right gaze preference. The fingerstick blood glucose level was 130 mg per deciliter (7.2 mmol per liter) and the blood pressure 120/60 mm Hg. The patient was transported to the emergency department of this hospital for further evaluation.

In the emergency department, the temporal temperature was 36.6°C, the blood pressure 143/63 mm Hg, the pulse 66 beats per minute, the respiratory rate 18 breaths per minute, and the oxygen saturation 98% while the patient was breathing ambient air. He was alert and interactive. There was a facial droop on the left side. There was no effort against gravity in the left arm. The patient was able to lift the left leg off the bed for 1 to 2 seconds. He had a right gaze deviation that could not be overcome and mild dysarthria. The remainder of the examination was normal. A diagnosis of stroke was considered, and emergency CT angiography was performed.

Dr. Gupta: CT angiography showed no evidence of acute territorial infarction and no changes in cerebrovascular disease.

Dr. Chui: On repeat physical examination performed after CT angiography, the gaze deviation and dysarthria had resolved, and strength was normal. Mild facial paralysis was present.

A diagnosis was made.

Differential Diagnosis

Dr. Albert Y. Hung: This 79-year-old man initially presented with involuntary movements of the left shoulder and face without associated loss of consciousness. Diagnosis of an unusual movement disorder, especially one that is present episodically, can be challenging. Videos brought in by the patient can be very useful.¹ Most movement disorders result from abnormal functioning of extrapyramidal circuits involving the basal ganglia, rather than a specific neuroanatomical lesion, and the first step toward diagnosis is to identify the type of abnormal movements.²

Four salient aspects of this patient’s involuntary movements can help in characterizing the movement disorder before generating a differential diagnosis. First, the movements were paroxysmal, lasting for short periods of time with resolution between episodes. Second, the movements were nonstereotyped, appearing randomly and variably. Third, the movements were restricted to the left side of his body throughout the course, localizing the disease process to the right cerebral hemisphere. Finally, the symptoms were progressive, increasing in both duration and frequency.

Movement Disorders

This patient had abnormal involuntary movements, symptoms indicative of a hyperkinetic movement disorder. Tremor, the most common hyperkinetic disorder, is unlikely because the patient did not have rhythmic movements. Dystonia is also unlikely, because he did not have sustained muscle contractions that were causing twisting or abnormal postures of the legs, arms, head, neck, or face. Although the patient initially described the movements as twitching, his later descriptions are not suggestive of myoclonus or tics, which manifest as sudden, rapid, recurrent movements.

This patient’s neurologist described the involuntary movements as “choreoathetoid” after reviewing a video of an episode. Chorea, athetosis, and ballism make up a spectrum of involuntary movements that often occur in combination. Chorea refers to involuntary movements that are “dancelike” — irregular, random, unintended, and flowing from one body part to another. When these movements are slow and writhing (with a lower amplitude) and involve the distal limbs, the term athetosis is used. The presence of both chorea and athetosis in the same patient is referred to as choreoathetosis. When the movements are fast and flinging (with a higher amplitude) and involve the proximal limbs, the term ballism is used. Although the description of this patient’s movements was not clearly suggestive of ballism, hemichorea and hemiballismus often occur together.

The term dyskinesia can refer to any abnormal movements and is often used to describe hyperkinetic disorders that are induced by specific drugs, such as tardive dyskinesia induced by dopamine antagonists or dyskinesia induced by levodopa in patients with Parkinson’s disease. Often, dyskinesia manifests as chorea or choreoathetoid movements, but chorea and dyskinesia are not synonymous. This patient appears to have involuntary dyskinesia with choreoathetosis as the primary phenomenology. Before constructing a differential diagnosis for dyskinesia in this patient, I will consider two conditions that mimic dyskinesia: seizures and functional movement disorder.

Seizures

Various movement disorders may be mistaken for seizures, although these movement disorders are not associated with EEG abnormalities during the episode. Patients with some forms of epilepsy may present with abnormal movements without other features that are typically associated with seizures, such as aura, change in responsiveness, incontinence, or a postictal state.^3,4 Seizures were initially suspected in this patient, and he was referred to the epilepsy clinic. Recurrent focal seizures were probably suspected because of the transient nature of the episodes. Initial MRI had shown a small abnormality in the right middle frontal gyrus, but this finding was not seen on follow-up imaging, which makes it unlikely to be related to the overall presentation. Baseline EEG had shown only brief left temporal slowing, without epileptiform abnormalities. The EEG was an interictal study, so the findings do not rule out seizures. However, the slowing was ipsilateral to the abnormal movements, so it is unlikely to be related to the episodes. In addition, the patient’s involuntary movements were nonstereotyped and nonrhythmic, which makes his presentation unlikely to be due to a seizure disorder.

Functional Movement Disorder

Because this patient’s movements diminished with the use of distraction techniques, a diagnosis of functional movement disorder was considered. Most cases of functional movement disorder begin abruptly after a trigger, such as a mild physical injury or illness; a psychological stressor can be present but is not required for diagnosis. Symptoms are typically most severe around the time of onset and may wax and wane over time. Although distractibility is a finding associated with functional disorders, abnormal movements that occur with nonfunctional syndromes can sometimes be suppressed by action or incorporated into voluntary movements in a manner that may appear distractible. Several clinical features in this patient make a diagnosis of functional disorder unlikely. Functional movement disorder is more common in women than in men, and the average age at onset is 40 years.⁵ In addition, tremor is the most common clinical phenotype seen in patients with functional movement disorder; chorea or choreoathetosis, which was seen in this patient, is very unusual in patients with functional movement disorder. Overall, functional movement disorder is unlikely to explain this patient’s presentation.

Dyskinesia

Primary paroxysmal dyskinesia refers to a group of heterogeneous syndromes characterized by recurrent involuntary movements that occur episodically and abruptly, without loss of consciousness.⁶ These disorders usually begin in childhood or young adulthood. Both the age of this patient and the described phenomenology make a diagnosis of primary paroxysmal dyskinesia unlikely.

The differential diagnosis in this case is therefore focused on causes of secondary dyskinesia, of which there are many.⁷ MRI ruled out the presence of a mass lesion suggestive of cancer. The patient had no history of acute illness suggestive of a viral or other infectious encephalitis, and there was no history of trauma or exposure to drugs or other toxins. Although his daughter mentioned trouble with memory, there was no compelling history suggestive of a neurodegenerative disease.

A common metabolic cause of secondary dyskinesia is diabetic striatopathy, a syndrome involving the acute-to-subacute onset of chorea and ballism in the context of hyperglycemia.⁸ This syndrome can occur as the initial manifestation of type 2 diabetes mellitus or as a complication of poorly controlled diabetes. Diabetic striatopathy is more likely to develop in women than in men, and the average age at onset is 70 years. Most patients present with hemichorea and hemiballismus, rather than bilateral symptoms. CT shows hyperdensity, and T1-weighted MRI shows hyperintensity, in the contralateral basal ganglia. However, this patient had no history of diabetes and had a normal blood glycated hemoglobin level, features that rule out a diagnosis of diabetic striatopathy.

Choreiform movements can also be a manifestation of autoimmune conditions.⁹ This patient’s initial presentation with unilateral shoulder and face movements would have suggested the possibility of faciobrachial dystonic seizures associated with anti–leucine-rich, glioma-inactivated 1 (anti-LGI1) encephalitis.¹⁰ This condition is often associated with hyponatremia, which was present in this patient. However, as the case evolved, leg involvement and sensory changes developed that would be atypical for anti-LGI1 encephalitis.

One key clue in this case is that the patient did not have an isolated movement disorder. In addition to motor symptoms, he had a variety of sensory symptoms involving both the left arm and the left leg. His first hospital admission was precipitated by an episode of unresponsiveness. The clinical event that led to his second presentation to the emergency department was distinctly different: an acute onset of speech difficulty accompanied by left hemiparesis and right gaze deviation that was worrisome for an acute right middle cerebral artery (MCA) syndrome. The symptoms resolved without intervention, which indicates that he may have had an acute transient ischemic attack (TIA). The most relevant imaging finding was severe cerebrovascular disease, including severe stenosis of the distal right CCA and proximal right ICA. Could this patient’s movement disorder be explained by a vascular lesion?

Limb-Shaking TIAs

Limb-shaking TIAs were first described by C. Miller Fisher in 1962.¹¹ In most case reports, these episodes are associated with high-grade stenosis of the ICA, which was seen in this patient.^12,13 The mechanism is thought to be cerebral hypoperfusion, and changes in posture or head position that decrease cerebral blood flow can precipitate these episodes. In this patient, the first episode of unresponsiveness that led to hospital admission occurred when he was sitting. He then had an acute episode involving right gaze preference that was provoked by exercise and was very suggestive of a TIA in the right MCA territory. These findings are highly suggestive of a diagnosis of limb-shaking TIAs, and I would refer this patient for emergency carotid endarterectomy.

Clinical Impression and Initial Management

Dr. Scott B. Silverman: When I evaluated this patient, his transient right gaze preference and left hemiparesis were consistent with a right MCA syndrome due to a TIA from symptomatic severe stenosis of the right ICA. The mechanism of this event was either artery-to-artery embolism or hypoperfusion. His previous, recurrent episodes of transient choreoathetosis on the left side that had occurred mainly while he was sitting, standing, or exercising were consistent with limb-shaking TIAs from hypoperfusion or low flow.

The pathogenesis of a low-flow state related to severe carotid stenosis resulting in limb-shaking TIAs is described in a small case series.¹⁴ In six out of eight patients, the transient, stereotyped, involuntary movements were eliminated with carotid artery revascularization. Positional cerebral ischemia in patients without orthostatic hypotension has been described.¹⁵

Treatment with atorvastatin was continued, the dose of aspirin was increased to 325 mg per day, and an intravenous heparin infusion was started. The strategy of permissive hypertension was used, with high blood pressure allowed to a maximum systolic blood pressure of 180 mm Hg. The patient was admitted to the stroke service, and carotid artery duplex ultrasonography was performed.

Dr. Gupta: Doppler ultrasonography of the carotid arteries (Figure 2) revealed markedly elevated Doppler flow velocities within the proximal right ICA. There was a parvus et tardus waveform in the distal right ICA, a finding indicative of low flow related to the more proximal high-grade stenosis. The Doppler waveform contours had poststenotic turbulence.

Pathological Discussion

Dr. Caroline F. Hilburn: The endarterectomy specimen included the carotid bifurcation and was notable for firm arterial walls, a finding consistent with calcification. On gross examination (Figure 3A), a large plaque was centered at the carotid bifurcation and protruded into the lumen, resulting in a maximal luminal stenosis of 80%. The plaque had an irregular and focally friable surface. On microscopic examination (Figure 3B), the plaque was characterized by extensive calcification. Some regions of the plaque had a smooth, healed fibrous cap, whereas other regions had an irregular surface suggestive of ulceration, which indicated potential sites of plaque rupture. Multiple smaller calcified plaques were present, affecting both branches of the artery.

Additional Management

Dr. Silverman: After the procedure, the patient had an uneventful recovery and was discharged home on the fifth hospital day. He was seen 1 month after discharge in the stroke prevention clinic. There had been no further episodes of involuntary movements or choreoathetosis and no stroke or TIA. The patient continues to take aspirin, atorvastatin, and antihypertensive medications.

Final Diagnosis

Presentation of Case

Dr. Christine M. Parsons (Medicine): A 75-year-old woman was evaluated at this hospital because of arthritis, abdominal pain, edema, malaise, and fever.

Three weeks before the current admission, the patient noticed waxing and waning “throbbing” pain in the right upper abdomen, which she rated at 9 (on a scale of 0 to 10, with 10 indicating the most severe pain) at its maximal intensity. The pain was associated with nausea and fever with a temperature of up to 39.0°C. Pain worsened after food consumption and was relieved with acetaminophen. During the 3 weeks before the current admission, edema developed in both legs; it had started at the ankles and gradually progressed upward to the hips. When the edema began to affect her ambulation, she presented to the emergency department of this hospital.

A review of systems that was obtained from the patient and her family was notable for intermittent fever, abdominal bloating, anorexia, and fatigue that had progressed during the previous 3 weeks. The patient reported new orthopnea and nonproductive cough. Approximately 4 weeks earlier, she had had diarrhea for several days. During the 6 weeks before the current admission, the patient had lost 9 kg unintentionally; she also had had pain in the wrists and hands, 3 days of burning and dryness of the eyes, and diffuse myalgias. She had not had night sweats, dry mouth, jaw claudication, vision changes, urinary symptoms, or oral, nasal, or genital ulcers.

The patient’s medical history was notable for multiple myeloma (for which treatment with thalidomide and melphalan had been initiated 2 years earlier and was stopped approximately 1 year before the current admission); hypothyroidism; chikungunya virus infection (diagnosed 7 years earlier); seropositive erosive rheumatoid arthritis affecting the hands, wrists, elbows, and shoulders (diagnosed 3 years earlier); vitiligo; and osteoarthritis of the right hip, for which she had undergone arthroplasty. Evidence of gastritis was reportedly seen on endoscopy that had been performed 6 months earlier. Medications included daily treatment with levothyroxine and acetaminophen and pipazethate hydrochloride as needed for cough. The patient consumed chamomile and horsetail herbal teas. She had no known allergies to medications, but she had been advised not to take nonsteroidal antiinflammatory drugs after her diagnosis of multiple myeloma.

Approximately 5 months before the current admission, the patient had emigrated from Central America. She lived with her daughter and grandchildren in an urban area of New England. She had previously worked in health care. She had no history of alcohol, tobacco, or other substance use. There was no family history of cancer or autoimmune, renal, gastrointestinal, pulmonary, or cardiac disease.

On examination, the temporal temperature was 37.1°C, the heart rate 106 beats per minute, the blood pressure 152/67 mm Hg, and the oxygen saturation 100% while the patient was breathing ambient air. She had a frail appearance and bitemporal cachexia. The weight was 41 kg and the body-mass index (the weight in kilograms divided by the square of the height in meters) 15.2. Her dentition was poor; most of the teeth were missing, caries were present in the remaining teeth, and the mucous membranes were dry. She had abdominal tenderness on the right side and mild abdominal distention, without organomegaly or guarding. Bilateral axillary lymphadenopathy was palpable. Infrequent inspiratory wheezing was noted.

The patient had swan-neck deformity, boutonnière deformity, ulnar deviation, and distal hyperextensibility of the thumbs (Fig. 1). Subcutaneous nodules were observed on the proximal interphalangeal joints of the second and third fingers of the right hand and on the proximal interphalangeal joint of the fourth finger of the left hand. Synovial thickening of the metacarpophalangeal joints of the second fingers was noted. There was mild swelling and tenderness of the wrists. She had pain with flexion of the shoulders and right hip, and there was subtle swelling of the shoulders and right knee. Pitting edema (3+) and vitiligo were noted on the legs. No sclerodactyly, digital pitting, telangiectasias, appreciable calcinosis, nodules, nail changes (including pitting), or tophi were present. The remainder of the examination was normal.

The blood levels of glucose, alanine aminotransferase, aspartate aminotransferase, bilirubin, globulin, lactate, lipase, magnesium, and phosphorus were normal, as were the prothrombin time and international normalized ratio; other laboratory test results are shown in Table 1. Urinalysis showed 3+ protein and 3+ blood, and microscopic examination of the sediment revealed 5 to 10 red cells per high-power field and granular casts. Urine and blood were obtained for culture. An electrocardiogram met (at a borderline level) the voltage criteria for left ventricular hypertrophy.

Table 1

Laboratory Data.

Dr. Rene Balza Romero: Computed tomography (CT) of the chest, abdomen, and pelvis, performed after the intravenous administration of contrast material, revealed scattered subcentimeter pulmonary nodules (including clusters in the right middle lobe and patchy and ground-glass opacities in the left upper lobe), trace pleural effusion in the left lung, coronary and valvular calcifications, and trace pericardial effusion, ascites, and anasarca. The scans also showed slight enlargement of the axillary lymph nodes (up to 11 mm in the short axis) bilaterally and a chronic-appearing compression fracture involving the T12 vertebral body.

Dr. Parsons: Morphine and lactated Ringer’s solution were administered intravenously. On the second day in the emergency department (also referred to as hospital day 2), the blood levels of haptoglobin, folate, and vitamin B₁₂ were normal; other laboratory test results are shown in Table 1. A rapid antigen test for malaria was positive. Wright–Giemsa staining of thick and thin peripheral-blood smears was negative for parasites; the smears also showed Döhle bodies and basophilic stippling. Antigliadin antibodies and anti–tissue transglutaminase antibodies were not detected. Tests for hepatitis A IgG and hepatitis C antibodies were positive. Tests for hepatitis B core and surface antibodies were negative. A test for human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) was negative.

Findings on abdominal ultrasound imaging performed on the second day (Fig. 2A and 2B) were notable for a small volume of ascites and kidneys with echogenic parenchyma. Ultrasonography of the legs showed no deep venous thrombosis. An echocardiogram showed normal ventricular size and function, aortic sclerosis with mild aortic insufficiency, moderate tricuspid regurgitation, a right ventricular systolic pressure of 39 mm Hg, and a small circumferential pericardial effusion. Intravenous hydromorphone was administered, and the patient was admitted to the hospital.

Imaging Studies of the Abdomen and Hands.

On the third day (also referred to as hospital day 3), nucleic acid testing for cytomegalovirus, Epstein–Barr virus, and hepatitis C virus was negative, and a stool antigen test for Helicobacter pylori was negative. An interferon-γ release assay for Mycobacterium tuberculosis was also negative. Oral acetaminophen and ivermectin and intravenous hydromorphone and furosemide were administered.

Dr. Balza Romero: Radiographs of the hands (Fig. 2C through 2F) showed joint-space narrowing of both radiocarpal joints and proximal interphalangeal erosions involving both hands. Radiographs of the shoulders showed arthritis of the glenohumeral joint and alignment suggestive of a tear of the right rotator cuff. A radiograph of the pelvis showed diffuse joint-space narrowing of the left hip, without osteophytosis, and an intact right hip prosthesis.

Dr. Parsons: Diagnostic tests were performed, and management decisions were made.

Differential Diagnosis

Dr. Beth L. Jonas: This patient is a 75-year-old woman who recently emigrated from Central America. She presented to this hospital with a multisystem disease involving the respiratory, gastrointestinal, renal, and musculoskeletal systems. Her medical history is notable for seropositive erosive rheumatoid arthritis and multiple myeloma, which had been treated with melphalan and thalidomide. Relevant clinical features on presentation include unintended weight loss and cachexia, axillary lymphadenopathy, serositis, cytopenia in two cell lines, hypocomplementemia, and elevated serum free kappa and lambda light-chain levels (with a normal free light-chain ratio) with no monoclonal spike. The white-cell count was elevated, but she had no eosinophilia. CT images of the chest showed scattered subcentimeter pulmonary nodules. With respect to the patient’s anemia, no schistocytes were present, the haptoglobin level was normal, and the iron studies were unremarkable. These findings, in combination with the elevated ferritin level, indicate anemia of chronic inflammation. The renal findings are most salient in the context of the patient’s hypertension, anasarca, elevated cystatin C level, active urinary sediment with proteinuria in the nephrotic range, and small, echogenic kidneys on ultrasonography.

In constructing a differential diagnosis, I will consider medication use, cancer, infectious disease, and autoimmune disease. Medications can be eliminated as the cause of this patient’s illness, since she was taking only levothyroxine, acetaminophen, and the antitussive agent pipazethate.

Cancer

The patient has a history of multiple myeloma, which may manifest with a multisystem disease involving the kidneys, but serum protein electrophoresis showed no monoclonal protein. Given the presence of nephrotic syndrome in the context of multiple myeloma, systemic immunoglobulin light-chain amyloidosis would be highest on the differential diagnosis with respect to cancer; however, the patient’s normal light-chain ratio makes this diagnosis unlikely. The development of myeloid neoplasms, such as acute myeloid leukemia, myelodysplastic syndromes, and myeloproliferative neoplasms, is important to consider in the context of previous treatment with alkylating agents,¹ which this patient had received. However, the peripheral-blood smear showed no findings that would indicate a hematologic cancer, and such a diagnosis would not explain the patient’s acute kidney injury with nephrotic-range proteinuria.

Infectious Disease

Several features of this patient’s case warrant special consideration, including her history of immunosuppression due to rheumatoid arthritis and to previously treated myeloma, along with the fact that she had emigrated from Central America, where certain infections may be prevalent. Infection with hepatitis A virus, hepatitis B virus, hepatitis C virus, HIV-1 and HIV-2, cytomegalovirus, Epstein–Barr virus, H. pylori, and M. tuberculosis can be ruled out on the basis of laboratory studies. A rapid antigen test for plasmodium species was reported to be positive, but this assay has a known cross-reactivity with rheumatoid factor.² Moreover, the thick and thin peripheral-blood smears were negative. Thus, malaria would be an unlikely diagnosis.

The patient has a history of infection with chikungunya virus, an arbovirus transmitted by a mosquito vector that has been responsible for large epidemics in the Americas since 2013.³ Acute symptoms include fever, rash, arthralgia, and myalgia. The development of a chronic arthritis that may meet the classification criteria for rheumatoid arthritis, as defined by the American College of Rheumatology and the European Alliance of Associations for Rheumatology, has been reported in up to 60% of patients infected with chikungunya virus.^4,5 In the context of this discussion, I considered whether chikungunya virus infection could be the cause of this patient’s symptoms, since this infection occurred before the diagnosis of rheumatoid arthritis. However, the degree of erosion and loss of joint space that was visible on radiographs would be most unusual for arthritis associated with chikungunya virus infection and would not explain the renal manifestations.

Strongyloidiasis is a helminth infection (caused by Strongyloides stercoralis) that is widespread in developing countries. Infection usually occurs through contact with soil, and most affected persons are asymptomatic. However, in immunosuppressed persons, strongyloides hyperinfection syndrome or a disseminated infection can develop as a consequence of accelerated autoinfection.⁶ The clinical presentation of strongyloides hyperinfection syndrome can include gastrointestinal symptoms (diarrhea, constipation, nausea, or vomiting), respiratory symptoms (cough, dyspnea, or wheezing), and rash due to migration of larvae through the subcutaneous tissues. Of note, only a minority of patients present with eosinophilia. Several case reports describe the development of nephrotic-range proteinuria, thrombotic microangiopathy, and IgA vasculitis in patients with strongyloides hyperinfection syndrome.^7-9 However, strongyloidiasis would not explain this patient’s cytopenias and hypocomplementemia.

Autoimmune Disease

The patient has a 3-year history of rheumatoid arthritis, although her clinical features of swan-neck deformity, boutonnière deformity, and joint instability suggest a longer duration of disease. We do not know whether she had received previous treatment with disease-modifying antirheumatic drugs or biologic agents, but the possible use of such treatments may be a consideration with respect to her progression of disease and overall degree of immunosuppression. The blood levels of rheumatoid factor and anti–cyclic citrullinated peptide antibodies were elevated, and radiographs of the hands showed erosive disease, although there was a relative paucity of metacarpophalangeal findings. A review of systems was negative for dry mouth, but her physical examination showed poor dentition and dry mouth — findings that make secondary Sjögren’s syndrome a consideration.

Renal disease can occur in patients with Sjögren’s syndrome. The two most typical presentations are tubulointerstitial nephritis and, less commonly, nephritic syndrome (membranoproliferative glomerulonephritis related to cryoglobulinemia). Tubulointerstitial nephritis may manifest with renal disease of varying severity, usually with a bland urinary sediment and often with abnormalities of tubular function such as distal renal tubular acidosis. Membranoproliferative glomerulonephritis caused by cryoglobulinemia is the most common glomerular disease associated with Sjögren’s syndrome. Although nephrotic-range proteinuria can occur with Sjögren’s syndrome, it is relatively uncommon.¹⁰ Renal disease is uncommon in patients with rheumatoid arthritis and is usually related to coexisting cardiovascular conditions. Medications used in the treatment of autoimmune disease — mainly nonsteroidal antiinflammatory drugs — may be associated with renal disease, but I would not expect the presence of an active urinary sediment, as was seen in this patient.

Amyloid A (AA) amyloidosis, a condition that is rare in the era of aggressive management of rheumatoid arthritis, has been described in patients with severe, long-standing seropositive erosive rheumatoid arthritis. Serum amyloid A (SAA) is a protein that is produced in the liver in response to chronic inflammation associated with interleukin-1, interleukin-6, and tumor necrosis factor α (TNF-α) in the context of chronic infections, autoimmune disease (classically rheumatoid arthritis), autoinflammatory disease, and cancers including renal cell carcinoma and non-Hodgkin’s lymphoma.¹¹ Signs and symptoms of AA amyloidosis are related to the deposition of the protein in organs, and patients often present with multisystem signs and symptoms. The kidney is the organ that is most often affected, but deposition can occur in the heart, gastrointestinal tract, nervous system, musculoskeletal system, and lungs. Proteinuria is the first clinical manifestation in almost 95% of patients with AA amyloidosis, and 50% of affected patients present with nephrotic syndrome.¹² The urinary sediment is generally bland, and complement levels in the blood are normal. AA amyloidosis remains on the differential diagnosis in this patient, but it would not completely explain her renal disease.

Hypocomplementemia

The key to this case is understanding the cause of this patient’s hypocomplementemia. Hypocomplementemia can be due to decreased complement production in the context of liver disease, congenital complement deficiency, or increased complement consumption resulting from activation of the innate immune system. This patient has no history of chronic liver disease and her laboratory test results indicated good hepatic synthetic function. Classical complement deficiency (including C4 deficiency) that begins early in life is associated with autoimmune disease, and early C3 deficiency is characterized by severe pyogenic infections. It would be unusual for a patient of this age to be deficient in both C3 and C4 without earlier clinical consequences. I therefore concluded that the hypocomplementemia in this case was related to complement consumption.

Rheumatic diseases that may be associated with prominent renal manifestations include antineutrophil cytoplasmic antibody–associated vasculitis, systemic sclerosis with renal crisis, cryoglobulinemic vasculitis, antiglomerular basement membrane disease, and systemic lupus erythematosus (SLE). Of those conditions, SLE would be the most likely to be manifested by an active urinary sediment and nephrotic-range proteinuria with consumption of both C3 and C4 in the context of fever, thrombocytopenia, and serositis. This patient’s fever, thrombocytopenia, and serositis also fit with this diagnosis.¹³

Because the patient has long-standing seropositive erosive rheumatoid arthritis, a diagnosis of AA amyloidosis is strongly suspected. Moreover, given the presence of thrombocytopenia, hypocomplementemia, and an active urinary sediment, I would recommend a kidney biopsy to evaluate for lupus nephritis and AA amyloidosis.

Pathological Discussion

Dr. Claire Trivin-Avillach: Testing for autoimmune antibodies was performed. A test for antinuclear antibodies was positive at a titer of 1:5120 with a homogeneous pattern, and a test for anti–double-stranded DNA antibodies was positive at a titer of 1:2560.

The diagnostic procedure in this case was a core-needle biopsy of the kidney. Examination of the specimen with light microscopy revealed 20 glomeruli, 45% of which were globally sclerosed, along with fibrosis involving approximately 60% of the interstitium and tubular atrophy. Diffusely enlarged glomeruli with thickened capillary walls and an expanded mesangium were weakly positive on periodic acid–Schiff staining; the glomeruli stained pale blue on Masson’s trichrome staining. Congo red staining revealed metachromatic salmon-colored deposition involving the glomeruli, the blood-vessel walls, and the interstitium, which was associated with apple-green birefringence when viewed under polarized light (Fig. 3A). In addition, mesangial and endocapillary hypercellularity was identified in approximately 30% of the nonsclerosed glomeruli and was associated with karyorrhexis (Fig. 3B). One cellular crescent was also detected. These features are characteristic of active proliferative glomerulonephritis.

Figure 3

Biopsy Specimen of the Kidney.

Immunofluorescence microscopy revealed prominent granular staining for IgG (4+), IgM (4+), C3 (3+), C1q (3+), IgA (1+), kappa (3+), and lambda (3+) along the glomerular basement membranes and within the mesangium, as well as focal granular deposits of IgG and C3 along the tubular basement membrane (Fig. 3C and 3D). Additional immunofluorescence studies showed strong positivity (4+) for SAA within the glomeruli, the blood-vessel walls, and the interstitium (Fig. 3E), whereas staining for beta₂-microglobulin, transthyretin, and apolipoprotein A1 was faint.

Electron microscopy revealed the presence of subendothelial and mesangial electron-dense deposits (with no substructure identified) adjacent to randomly arranged fibrils (measuring 8.2 to 10.6 nm in diameter) within the glomerular basement membranes and the mesangium (Fig. 3F). Glomerular endothelial cells appeared reactive and contained tubuloreticular inclusions, features that were suggestive of interferon-mediated activation.

The findings on Congo red staining were characteristic of amyloidosis with typical birefringent material. The strong positivity of SAA within the deposits as compared with the faint staining of other reactants identified the type of amyloid as SAA, which is consistent with the patient’s history of rheumatoid arthritis. The biopsy also showed an immune complex–mediated proliferative glomerulonephritis with a “full house” pattern (defined as positivity for the three immunoglobulin classes IgG, IgM, and IgA and the two complement components C3 and C1q, in reference to the “full house” hand in a poker game). Immune complex–mediated proliferative glomerulonephritis has been reported in patients with rheumatoid arthritis who were receiving anti–TNF-α therapy,¹⁴ which was not the case in this patient. The positive test for hepatitis C antibodies prompted consideration of hepatitis C–related membranoproliferative glomerulonephritis. However, taken together, the negative nucleic acid test for hepatitis C virus, the full house pattern on immunofluorescence, the tubular basement membrane deposits, and the positive test for anti–double-stranded DNA antibodies favor a diagnosis of lupus nephritis of at least class III (defined as focal proliferative glomerulonephritis), according to the criteria of the International Society of Nephrology and the Renal Pathology Society, superimposed on AA amyloidosis.

Discussion of Management

Dr. Pui W. Cheung: On the basis of the finding of echogenic kidneys on ultrasonography and the findings of extensive interstitial fibrosis and tubular atrophy on kidney biopsy, we know that this patient has advanced chronic kidney disease that is unlikely to be reversible. The patient is also noted to have a markedly lower glomerular filtration rate (GFR) than that predicted by the blood creatinine level owing to the presence of cachexia, and this is substantiated by the cystatin C–based GFR and a 24-hour creatinine clearance of 22 ml per minute per 1.73 m² of body-surface area. The typical induction therapy for stage III or IV lupus nephritis consists of high-dose glucocorticoids and either mycophenolate mofetil or cyclophosphamide. Other reasonable alternatives for initial therapy include mycophenolate mofetil in combination with either a calcineurin inhibitor or belimumab, or cyclophosphamide in combination with belimumab.¹⁵ Hydroxychloroquine is also recommended as part of the therapy, since it has shown benefits in improving the response to treatment and reducing disease flare.¹⁶ Mycophenolate mofetil and cyclophosphamide have similar efficacy with respect to clinical response, which includes a reduction in proteinuria and either an improvement in renal function or stabilization of renal function; the risks of infections and adverse events associated with these medications are also similar.^17,18

Given the severity of the lupus nephritis with overlying AA amyloidosis from active rheumatoid arthritis, the treatment options proposed were high-dose glucocorticoids and rituximab with either mycophenolate mofetil or cyclophosphamide.¹⁹ After discussions with multidisciplinary consultants from rheumatology, infectious diseases, and nephrology, lingering concerns were raised about infection and patient frailty; ultimately, the decision was made to initiate high-dose glucocorticoid therapy in combination with mycophenolate mofetil, rituximab, and hydroxychloroquine.

The patient’s mycophenolate mofetil dose regimen was inconsistent owing to gastrointestinal side effects, and the treatment was eventually withheld because of pancytopenia and fever. Unfortunately, her kidney function worsened, and renal replacement therapy was initiated within 3 weeks after the start of the induction therapy. The cause of her renal failure was thought to be disease progression, compounded by hemodynamically mediated tubular injury in the context of infection. While the administration of mycophenolate mofetil was stopped, treatment with rituximab was continued, with slow tapering of the glucocorticoid dose at the direction of the rheumatologist. She remained dependent on dialysis and was deemed to have end-stage kidney disease after 3 months of dialysis.

Dr. Lisa G. Criscione-Schreiber: The patient has SLE with nephritis, seropositive erosive rheumatoid arthritis, and systemic AA amyloidosis. AA amyloidosis is rare owing to the availability of effective therapies for rheumatoid arthritis and is managed through aggressive treatment of inflammation due to rheumatoid arthritis. Reports addressing the management of rheumatoid arthritis–induced AA amyloidosis generally cite stability of end-organ damage caused by AA amyloid as evidence of effective management of the condition (through treatment of the inflammation of rheumatoid arthritis). Methotrexate, the cornerstone of treatment for rheumatoid arthritis, is contraindicated in this case owing to the presence of kidney disease. The alkylating agent cyclophosphamide has been reported to be effective for the treatment of AA amyloidosis from rheumatoid arthritis²⁰ and has known efficacy in patients with lupus nephritis, both of which make it a viable treatment option. Rituximab has also been reported to be effective for managing rheumatoid arthritis–induced AA amyloidosis,²¹ is approved for the treatment of rheumatoid arthritis, and is used for manifestations of SLE, including thrombocytopenia and nephritis. Although anti–TNF-α agents, abatacept, and Janus kinase inhibitors are reported to be effective for the treatment of AA amyloidosis in patients with rheumatoid arthritis,²² recent publications have coalesced on the ability of anti–interleukin-6 therapy to block interleukin-6–induced hepatic production of SAA.^23-25

The overlap of seropositive erosive rheumatoid arthritis and SLE (sometimes termed “rhupus”) usually resembles rheumatoid arthritis more than SLE; manifestations include thrombocytosis, leukocytosis, an elevated erythrocyte sedimentation rate, an elevated blood level of C-reactive protein, and the presence of marginal erosions on radiographs.²⁶ In contrast, SLE without seropositive erosive rheumatoid arthritis characteristically manifests with thrombocytopenia, leukopenia, and an elevated erythrocyte sedimentation rate but usually not an elevated C-reactive protein level; in addition, nonerosive inflammatory arthritis with reversible deformities is commonly observed. This patient had a mixed laboratory profile, on the basis of the results of antinuclear antibody and anti–double-stranded DNA antibody tests. The challenge of treating an overlap syndrome of rheumatoid arthritis and SLE is choosing disease-modifying antirheumatic drugs that are effective and safe in both conditions. This patient’s most severe disease manifestation is lupus nephritis; therefore, the treatment regimen must target nephritis along with the AA amyloidosis and inflammatory arthritis.

As noted earlier, current induction therapy for lupus nephritis includes either mycophenolate mofetil or cyclophosphamide. Mycophenolate mofetil may provide inadequate treatment of the rheumatoid arthritis and amyloidosis, whereas cyclophosphamide would treat the lupus nephritis, has possible efficacy for treatment of the AA amyloidosis, and would treat the rheumatoid arthritis. Rituximab could be added to cyclophosphamide or mycophenolate mofetil to treat the rheumatoid arthritis and resultant AA amyloidosis and could also possibly help treat the lupus nephritis. The addition of anti–interleukin-6 therapy to mycophenolate mofetil or cyclophosphamide is an intriguing option that may effectively treat the rheumatoid arthritis and subsequent AA amyloidosis. The addition of belimumab to mycophenolate mofetil or cyclophosphamide has been reported to improve renal response in patients with lupus nephritis,²⁷ as has the addition of voclosporin to mycophenolate mofetil.²⁸ However, belimumab is ineffective for the treatment of rheumatoid arthritis, and voclosporin has not been studied in patients with rheumatoid arthritis or in those with a GFR of 45 milliliters per minute or less. The high-dose glucocorticoids that are used in induction therapy for lupus nephritis will effectively manage this patient’s inflammatory arthritis and probably also the subsequent AA amyloidosis. Finally, it is important that every patient with lupus nephritis receive hydroxychloroquine, which improves the treatment response to induction therapy.²⁹

Follow-up

Dr. Parsons: The patient’s hospital course was further complicated by suspected immune-mediated thrombocytopenia, for which she received intravenous immune globulin. Her pancytopenia and arthritis ultimately abated. Unfortunately, she did not have renal recovery and continues to receive hemodialysis. After a prolonged hospital course, she was discharged home.

Final Diagnosis

Overlap syndrome of rheumatoid arthritis and systemic lupus erythematosus complicated by proliferative lupus nephritis, superimposed on amyloid A amyloidosis.

Abstract

Sacituzumab govitecan (SG) significantly improved progression-free survival (PFS) and overall survival (OS) versus chemotherapy in hormone receptor-positive human epidermal growth factor receptor 2-negative (HR⁺HER2^-) metastatic breast cancer (mBC) in the global TROPiCS-02 study. TROPiCS-02 enrolled few Asian patients. Here we report results of SG in Asian patients with HR⁺HER2^- mBC from the EVER-132-002 study. Patients were randomized to SG (n = 166) or chemotherapy (n = 165). The primary endpoint was met: PFS was improved with SG versus chemotherapy (hazard ratio of 0.67, 95% confidence interval 0.52-0.87; P = 0.0028; median 4.3 versus 4.2 months). OS also improved with SG versus chemotherapy (hazard ratio of 0.64, 95% confidence interval 0.47-0.88; P = 0.0061; median 21.0 versus 15.3 months). The most common grade ≥3 treatment-emergent adverse events were neutropenia, leukopenia and anemia. SG demonstrated significant and clinically meaningful improvement in PFS and OS versus chemotherapy, with a manageable safety profile consistent with prior studies. SG represents a promising treatment option for Asian patients with HR⁺HER2^- mBC (ClinicalTrials.gov identifier no. NCT04639986 ).

Abstract

Irritable bowel syndrome with diarrhea (IBS-D) is a common and chronic gastrointestinal disorder that is characterized by abdominal discomfort and occasional diarrhea. The pathogenesis of IBS-D is thought to be related to a combination of factors, including psychological stress, abnormal muscle contractions, and inflammation and disorder of the gut microbiome. However, there is still a lack of comprehensive analysis of the logical regulatory correlation among these factors. In this study, we found that stress induced hyperproduction of xanthine and altered the abundance and metabolic characteristics of Lactobacillus murinus in the gut. Lactobacillus murinus-derived spermidine suppressed the basal expression of type I interferon (IFN)-α in plasmacytoid dendritic cells by inhibiting the K63-linked polyubiquitination of TRAF3. The reduction in IFN-α unrestricted the contractile function of colonic smooth muscle cells, resulting in an increase in bowel movement. Our findings provided a theoretical basis for the pathological mechanism of, and new drug targets for, stress-exposed IBS-D.

Keywords: AdorA2B; Lactobacillus murinus; irritable bowel syndrome with diarrhea; spermidine; stress; type I interferon; xanthine.

Abstract

The severe bronchiolitis endotype characterized by a high abundance of H. influenzae, high proportion of RV-A and RV-C infections, and high asthma genetic risk had a significantly higher risk for developing asthma.

Background: Infants with bronchiolitis are at increased risk for developing asthma. Growing evidence suggests bronchiolitis is a heterogeneous condition. However, little is known about its biologically distinct subgroups based on the integrated metagenome and asthma genetic risk signature and their longitudinal relationships with asthma development.

Methods: In a multi-center prospective cohort study of infants with severe bronchiolitis (i.e., bronchiolitis requiring hospitalization), we profiled nasopharyngeal airway metagenome and virus at hospitalization, and calculated the polygenic risk score of asthma. Using similarity network fusion clustering approach, we identified integrated metagenome-asthma genetic risk endotypes. We also examined their longitudinal association with the risk of developing asthma by age six years.

Results: Of 450 infants with bronchiolitis (median age, 3 months), we identified five distinct endotypes-characterized by their nasopharyngeal metagenome, virus, and asthma genetic risk profiles. Compared with endotype A infants (who clinically resembled "classic" bronchiolitis), endotype E infants (characterized by a high abundance of H. influenzae, high proportion of RV-A and RV-C infections, and high asthma genetic risk) had a significantly higher risk for developing asthma (35.9% versus 16.7%; OR_adj, 2.24; 95%CI, 1.02-4.97; p=0.046). The pathway analysis showed that endotype E had enriched microbial pathways (e.g., glycolysis, L-lysine, arginine metabolism) and host pathways (e.g., IFNs, IL-6/JAK/STAT3, fatty acids, MHC, and immunoglobin-related) (FDR<0.05). Additionally, endotype E had a significantly higher proportion of neutrophils (FDR<0.05).

Conclusion: In this multi-center prospective cohort study of infant bronchiolitis, the clustering analysis of integrated-omics data identified biologically distinct endotypes with differential risks for developing asthma.

Summary

Background

Radiology-based prognostic biomarkers play a crucial role in patient counseling, enhancing surveillance, and designing clinical trials effectively. This study aims to assess the predictive significance of preoperative CT-based tumor contour irregularity in determining clinical outcomes among patients with renal cell carcinoma (RCC).

Methods

We conducted a retrospective multi-institutional review involving 2218 patients pathologically diagnosed with RCC. The training and internal validation sets included patients at Zhongshan Hospital between January 2009 and August 2019. The external test set comprised patients from the First Affiliated Hospital, Zhejiang University School of Medicine (January 2016 to January 2018), the Xiamen Branch of Zhongshan Hospital (November 2017 to June 2023), and the Cancer Imaging Archive. The contour irregularity degree (CID), quantified as the ratio of irregular cross-sections to the total tumor cross-sections, was analyzed for its prognostic relevance across different subgroups of RCC patients. A novel CID-based scoring system was developed, and its predictive efficacy was evaluated and compared with existing prognostic models.

Findings

The CID exhibited significant discriminatory power in predicting overall survival (OS), recurrence-free survival (RFS), and disease-specific survival (DSS) among patients with RCC tumors measuring 3 cm or larger (all p < 0.001). Multivariate analyses confirmed the CID as an independent prognostic indicator. Notably, the CID augmented prognostic stratification among RCC patients within distinct risk subgroups delineated by SSIGN models and ISUP grades. The CID-based nomogram (C-Model) demonstrated robust predictive performance, with C-index values of 0.88 (95%CI: 0.84–0.92) in the training set, 0.92 (95%CI: 0.88–0.98) in the internal validation set, and 0.86 (95%CI: 0.81–0.90) in the external test set, surpassing existing prognostic models.

Interpretation

Routine imaging-based assessment of the CID serves as an independent prognostic factor, offering incremental prognostic value to existing models in RCC patients with tumors measuring 3 cm or larger.
