Finely ground hydrous magnesium silicate, or talcum powder, finds significant utilization in the cosmetic industry for its absorbency. Long-term inhalation exposure to talc is associated with an interstitial lung disease termed talcosis, commonly seen in miners, industry workers, and IV drug users. However, it may unfortunately manifest in the general public secondary to chronic inhalation of talc-containing products. Here, we present a unique case of talcum powder pica induced pulmonary talcosis. 31-year-old female from Jamaica presented for evaluation of mild hemoptysis, subjective fevers, cough, weight loss, and dyspnea of three months duration. Vital signs were unremarkable. Physical examination was notable for bilateral costochondral tenderness. Labs were significant for elevated ESR and CRP. CT chest revealed bilateral apical predominant dense, consolidative airspace opacities with adjacent branching nodular densities and diffuse ground-glass opacification with innumerable miliary nodules. The patient was admitted for tuberculosis rule out. QuantiFERON-TB Gold and four sputum AFB smears and cultures resulted negative. Further questioning revealed history of intentional oral talcum powder ingestion from childhood until age 27. She underwent hemoptysis work-up in Jamaica including lung biopsy for confirmation of suspected sarcoidosis. However, results of pathology confirmed a diagnosis of pulmonary talcosis consistent with her history. Given CT findings, SARS-CoV-2 testing was repeated and resulted positive. However, pharmacologic therapy was not indicated given lack of oxygen requirement. She was discharged with outpatient Pulmonary follow-up. Pulmonary talcosis develops with chronic inhalation or intravenous exposure. Talco-silicosis and talco-asbestosis are seen in miners and industrial workers exposed to high levels of inhaled impure talc. Chronic exposure to cosmetic talc also has the potential to cause talcosis. Lung parenchymal changes are not always acutely evident and may manifest up to four decades after inciting events. Pathologic changes occur in the following three major patterns: diffuse interstitial fibrosis, nodular fibrosis, and foreign body granulomatosis. Pica is defined as the persistent consumption of nonnutritive substances that is not socially acceptable and occurs in the context of mental or medical disorders. As a result of an underlying psychiatric diagnosis, pica behavior was the driving force behind our patient's consumption of talc, resulting in chronic, repetitive inhalation exposure, and ultimately led to the development of pulmonary talcosis. Although our patient reported cessation of consumption four years prior, her exposure over time was significant enough for talcosis to develop. If pica was recognized and intervened upon in childhood, she may have been spared permanent lung injury.
细碎的含水硅酸镁,或滑石粉,因其吸收性在化妆品工业中有重要的应用。长期吸入滑石与一种称为滑石中毒的肺间质性疾病有关,常见于矿工、工业工人和静脉注射吸毒者。然而,不幸的是,它可能在公众中继发于长期吸入含滑石粉的产品。在这里,我们提出一个独特的案例滑石粉异食癖诱发肺滑石症。来自牙买加的31岁女性因轻度咯血、主观发热、咳嗽、体重减轻和持续三个月的呼吸困难前来接受评估。生命体征不明显。体格检查发现双侧肋软骨压痛。实验室ESR和CRP均升高。胸部CT示双侧根尖为主致密,实变性空域混浊伴邻近分支性结节密度,弥漫性磨玻璃混浊伴无数军事结节。病人因肺结核而入院。QuantiFERON-TB Gold和4个痰AFB涂片和培养结果均为阴性。进一步的询问揭示了从童年到27岁有意口服滑石粉的历史。她在牙买加接受了咯血检查,包括肺活检以确认疑似结节病。然而,病理结果证实肺部滑石症的诊断与她的病史一致。鉴于CT检查结果,重复进行了SARS-CoV-2检测,结果为阳性。然而,由于缺氧,不需要药物治疗。出院后进行门诊肺部随访。慢性吸入或静脉接触可发生肺滑石症。滑石矽肺病和滑石石棉沉滞症见于大量吸入不纯滑石的矿工和工业工人。长期接触化妆品中的滑石也有可能导致滑石中毒。肺实质改变并不总是非常明显,可能在刺激事件发生后40年才出现。病理改变主要表现为弥漫性间质纤维化、结节性纤维化和异物肉芽肿病。异食癖被定义为持续食用非营养物质,这是社会所不能接受的,发生在精神或医学疾病的背景下。由于潜在的精神诊断,异食癖行为是我们的患者食用滑石粉的驱动力,导致慢性、重复的吸入暴露,并最终导致肺部滑石症的发展。虽然我们的患者报告四年前停止使用,但随着时间的推移,她的暴露足以导致滑石症的发展。如果异食癖在儿童时期得到识别和治疗,她可能不会受到永久性肺损伤。

Introduction: Amiodarone is one of the most commonly prescribed antiarrhythmic medications in the United States. Adverse effects have been shown to affect multiple organ systems including cardiac, thyroid, hepatic, ocular and pulmonary. Pulmonary toxicity can vary in presentation from interstitial pneumonitis, eosinophilic pneumonia, organizing pneumonia and acute respiratory distress syndrome (ARDS)1. This is a case of ARDS caused by Amiodarone. Case Presentation: This is a case of an 81 yo male with a history of atrial fibrillation (on Amiodarone 200 mg daily), mechanical aortic valve replacement and diabetes who presented to the hospital with a four week history of dry cough and one week of dyspnea on exertion. He was treated for community acquired pneumonia prior to admission with steroids, Azithromycin, Ceftriaxone and Levofloxacin. On arrival he was afebrile, but hypoxic requiring oxygen support with nasal cannula. Physical exam was concerning for an ill appearing, lethargic elderly gentleman with extensive crackles throughout both lung fields more concentrated in the upper lobes. Laboratory was significant for negative SARS Coronavirus RNA PCR and Leukocytosis 14.7. Computed-tomography revealed extensive bilateral consolidations with air bronchograms worse in the upper lobes. As his clinical status worsened requiring use of non-invasive ventilation and transfer to the intensive care unit, it became clear that this was not an infectious process;work up thus far had been negative. Amiodarone was discontinued and the patient was started on Diltiazem and pulse dose steroids. Within four days, his respiratory and mental status improved. Discussion: Amiodarone pulmonary toxicity has been associated with higher doses of 400 mg, but 1.6% of cases are reported with less, making this case unique. The pathology appears to be related to direct cytotoxic effect and indirect immunological reaction. Patients will usually present with a nonproductive cough and shortness of breath. Imaging is key for diagnosis, demonstrating diffuse patchy infiltrates;with a preference to the right lung and upper lobes. Treatment centers on discontinuation of the drug and 40-60 mg of Prednisone per day tapered over the period of a few months2.
简介:胺碘酮是美国最常用的抗心律失常药物之一。不良反应已显示影响多个器官系统,包括心脏,甲状腺,肝脏,眼和肺。肺毒性可表现为间质性肺炎、嗜酸性肺炎、组织性肺炎和急性呼吸窘迫综合征(ARDS)1。这是一例胺碘酮引起的急性呼吸窘迫综合征。病例介绍:这是一个81岁的男性病例,有房颤史(每天服用胺碘酮200毫克),机械主动脉瓣置换术和糖尿病,以干咳史4周和用力时呼吸困难1周就诊。入院前,他接受了类固醇、阿奇霉素、头孢曲松和左氧氟沙星的社区获得性肺炎治疗。到达时,他发烧,但缺氧,需要用鼻插管吸氧。体格检查中发现一位表现不佳,嗜睡的老年绅士,双肺广泛的裂纹,更集中在上肺叶。实验室SARS冠状病毒RNA PCR阴性,白细胞增多14.7。计算机断层扫描显示广泛的双侧实变,肺上叶空气支气管征加重。随着他的临床状况恶化,需要使用无创通气并转移到重症监护病房,很明显这不是一个传染性过程;到目前为止,工作一直是阴性的。停用胺碘酮,患者开始使用地尔硫卓和脉冲剂量类固醇。四天之内,他的呼吸和精神状况都有所改善。讨论:胺碘酮肺毒性与较高剂量400mg有关,但1.6%的病例报告剂量低于400mg,使本病例独特。病理表现与直接的细胞毒作用和间接的免疫反应有关。患者通常表现为非生产性咳嗽和呼吸短促。影像学是诊断的关键,表现为弥漫性斑片状浸润,优先于右肺和上肺叶。治疗的重点是停药,每天40-60毫克的强的松在几个月内逐渐减少。

Hydrogen peroxide is a chemical commonly used as a household antiseptic for cleaning and disinfecting. Chronic inhalation of hydrogen peroxide is described in case reports as causing interstitial lung disease with radiographic images demonstrating septal line thickening, honeycombing, and traction bronchiectasis with associated ground glass opacification. In a literature review, no cases of acute hydrogen peroxide inhalation induced lung injury have been previously described. This is a case of acute hydrogen peroxide induced pneumonitis initially masquerading as Covid-19 pneumonia. An 82-year-old male with a pertinent history of diastolic heart failure, obstructive sleep apnea, and chronic obstructive pulmonary disease presented with worsening dyspnea and morning hemoptysis. He endorsed a COVID-19 exposure two weeks previously. Upon initial evaluation, he was afebrile and hemodynamically normal, with tachypnea and requiring 6 liters of supplemental oxygen to maintain spo2> 88%. Pulmonary auscultation revealed clear breath sounds and no signs of fluid overload were evident on the remainder of the physical exam. The initial chest x-ray and CT imaging demonstrated multifocal, bilateral, hazy consolidations with increased interstitial markings concerning for COVID-19 pneumonia. Pertinent lab results revealed negative COVID-19 and viral respiratory PCR results, and respiratory cultures with no growth of pathogenic bacteria. An echocardiogram revealed new systolic dysfunction with a reduced ejection fraction of 35-40%. The patient continued to have severe dyspnea and hypoxemia despite treatment for heart failure, COPD, and bacterial pneumonia consisting of diuretics, bronchodilators, and antibiotics. On further interview the patient recounted mixing hydrogen peroxide in his CPAP humidifier for the previous week before admission, based on a friend's advice in preventing COVID-19. The patient was subsequently initiated on systemic glucocorticoid therapy and had significant improvement in hypoxemia and dyspnea and oxygen requirements decreased from 6L to 2L nasal cannula at time of discharge. In light of the recent influential media attention and fear, cleaning products such as bleach have received disproportionate attention in the killing of the COVID-19 virus. Similarly, hydrogen peroxide is used as a disinfectant, which was intentionally inhaled in large amounts and over a one-week duration in this case. Prior case reports describe environmental and occupational exposure over 3-5 years developing into a non-specific interstitial pneumonia pattern. This case demonstrates a rare acute pneumonitis after the recent use of hydrogen peroxide in a CPAP humidifier. Inhalation of hydrogen peroxide may produce an acute pneumonitis distinct from what has been described previously with chronic inhalation.
过氧化氢是一种常用的化学物质,用于家庭清洁和消毒。慢性吸入过氧化氢在病例报告中被描述为引起间质性肺疾病,x线图像显示中隔线增厚、蜂窝状和牵引性支气管扩张伴磨砂玻璃混浊。在一篇文献综述中,没有急性过氧化氢吸入引起肺损伤的病例以前被描述过。这是一例急性过氧化氢引起的肺炎,最初伪装成Covid-19肺炎。82岁男性,有舒张性心力衰竭、阻塞性睡眠呼吸暂停和慢性阻塞性肺疾病相关病史,表现为呼吸困难加重和晨咯血。他在两周前支持了COVID-19暴露。初步评估时,他不发热,血流动力学正常,呼吸急促,需要6升补氧维持血氧饱和度。88%。肺听诊显示清晰的呼吸音,其余体检未见明显的液体超载迹象。最初的胸部x线和CT成像显示多灶,双侧,模糊实变,间质标记增加,与COVID-19肺炎有关。相关实验室结果显示COVID-19和病毒性呼吸道PCR结果为阴性,呼吸道培养未见致病菌生长。超声心动图显示新的收缩功能障碍,射血分数降低35-40%。尽管使用利尿剂、支气管扩张剂和抗生素治疗心衰、COPD和细菌性肺炎,患者仍有严重的呼吸困难和低氧血症。在进一步的采访中,患者讲述了入院前一周根据朋友预防COVID-19的建议,在他的CPAP加湿器中混合过氧化氢。患者随后开始接受全身糖皮质激素治疗,低氧血症和呼吸困难明显改善,出院时鼻插管需氧量从6L降至2L。鉴于最近有影响力的媒体的关注和恐惧,漂白剂等清洁产品在杀死COVID-19病毒方面受到了不成比例的关注。同样,过氧化氢被用作消毒剂,在这种情况下,故意大量吸入,持续时间超过一周。先前的病例报告描述了环境和职业暴露超过3-5年发展成非特异性间质性肺炎模式。这个病例显示了一个罕见的急性肺炎后,最近使用过氧化氢在CPAP加湿器。吸入过氧化氢可引起急性肺炎,不同于以前所描述的慢性吸入。

Multiple chemotherapy medications are known to cause acute lung injury. One medication that causes injury to the lungs and can present with hypoxia is pomalidomide, a medication used for multiple myeloma. Chemotherapy-induced lung injury is commonly mistaken for infectious pneumonia. The diagnosis becomes difficult since patients are immunosuppressed and prone to infection. The presentation is complicated further during pandemics. Coronavirus Disease 19 (COVID19) has become a very common diagnosis during the pandemic in 2020. Multiple diagnostic tests are required to rule out infectious processes including that of less common organism. To ultimately deem the injury to be caused by medication side-effect is a diagnosis of exclusion. The following case illustrates the complexity of the diagnosis. Multiple case reports show a potential association between pomalidomide and acute lung injury. Lung injury arises about 120 to 480 days after continuous use. Pomalidomide promotes T-cell proliferation and secretion of IL-2 and INF-y. IL-2 causes increased vascular permeability leading to pulmonary edema and acute lung injury. INF-y further promotes hyperoxia-induced lung injury. Treatment is with pomalidomide cessation and corticosteroids. In some cases, the medication can be reintroduced but there have been reports of recurrence.
已知多种化疗药物可引起急性肺损伤。泊马度胺是一种治疗多发性骨髓瘤的药物,它会导致肺部损伤并伴有缺氧。化疗引起的肺损伤常被误认为感染性肺炎。诊断变得困难,因为患者免疫抑制和易感染。在大流行期间,这种表现更加复杂。2019冠状病毒病(covid - 19)已成为2020年大流行期间非常常见的诊断。需要进行多种诊断测试以排除感染过程,包括不太常见的生物体。最终将损伤认定为药物副作用所致,是一种排除性诊断。下面的病例说明了诊断的复杂性。多个病例报告显示泊马度胺与急性肺损伤之间的潜在关联。持续使用后约120至480天出现肺损伤。波马度胺促进t细胞增殖和IL-2和INF-y的分泌。IL-2引起血管通透性增加,导致肺水肿和急性肺损伤。INF-y进一步促进高氧诱导的肺损伤。治疗是停用泊马度胺和皮质类固醇。在某些情况下,药物可以重新引入,但有复发的报告。

When Antibiotics, Diuresis and Steroids Are Not Enough - A Fatal Case of Amiodarone-Induced Pulmonary Toxicity 当抗生素、利尿和类固醇不够时——胺碘酮引起肺毒性的致命病例
Pub Date : 2021-01-01 DOI: 10.1164/ajrccm-conference.2021.203.1_meetingabstracts.a2149

A 74-year-old man with hypertension, chronic kidney disease, coronary artery disease, chronic systolic heart failure and prior cardiac arrest due to ventricular tachycardia status-post implantable cardioverter-defibrillator placement presented to the emergency department with worsening dyspnea. He reported shortness of breath with exertion and dry nonproductive cough which had gradually progressed over the past several months. He reported compliance with home medications although could not specify which medications he was taking. He previously worked as a plumber, without known environmental exposures, sick contact, travel or extensive tobacco use. Physical exam revealed diffuse crackles in the bilateral posterior lung fields, jugular venous distension and pitting bilateral lower extremity edema. Due to suspicion for community acquired pneumonia and acute on chronic heart failure exacerbation, he was admitted to the hospital for intravenous (IV) antibiotics and diuresis. Transthoracic echocardiogram showed a reduced left ventricular ejection fraction and elevated pulmonary artery pressures, otherwise no valvulopathy, shunting or right ventricular dysfunction. His fluid status improved, although his oxygen requirements continued to rise. He was escalated from high flow nasal cannula to bilevel positive airway pressure ventilation, and transferred to the medical intensive care unit. Computed tomography pulmonary angiogram revealed no evidence of pulmonary embolism, although was significant for bilateral diffuse ground glass opacities with septal thickening, honeycombing and traction bronchiectasis. Respiratory viral panel, COVID-19 testing, fungal serologies and autoimmune/vasculitis workup were negative. Outside records consisted of recent diagnostic bronchoscopy which yielded unremarkable cytology and cultures, pulmonary function tests demonstrating restrictive lung pattern and severely reduced diffusion capacity of carbon monoxide, and normal ventilation-perfusion scan. Calls were placed to outside providers who confirmed that the patient had been on high-dose amiodarone (400 mg twice daily) for over the past decade, as previous attempts transition down or off amiodarone had led to his prior cardiac arrest. After discussion in multidisciplinary conferences, the patient was started on high-dose IV steroids due to suspicion for amiodarone-induced pulmonary toxicity (AIPT). Unfortunately, he decompensated further, and his family ultimately pursued hospice care. While the incidence of AIPT is less than 10-15%, this case serves a reminder of the potentially fatal pulmonary adverse events associated with amiodarone use, and emphasizes upon the essential need for close multiorgan monitoring while on the medication. There remains a strong demand for further research to elucidate dose-dependent and duration-dependent relationships between amiodarone use and associated pulmonary toxicity, as well as identifying predisposing risk factors.
一名74岁男性患者,患有高血压、慢性肾病、冠状动脉疾病、慢性收缩期心力衰竭和先前因室性心动过速状态引起的心脏骤停,植入式心律转复除颤器放置后出现呼吸困难加重。他报告在过去几个月里逐渐加重的呼吸短促和干咳。他报告说他遵守了家庭药物治疗,但不能具体说明他服用的是哪种药物。他以前是一名水管工,没有接触过环境,没有接触过疾病,没有旅行过,也没有大量吸烟。体格检查示双侧肺后野弥漫性裂纹,颈静脉扩张,双侧下肢凹陷性水肿。因怀疑社区获得性肺炎及急性或慢性心力衰竭加重,入院静脉注射抗生素及利尿。经胸超声心动图显示左心室射血分数降低,肺动脉压升高,除此之外无瓣膜病、分流或右室功能障碍。他的体液状况有所改善,但他的需氧量继续上升。他从高流量鼻插管升级到双水平气道正压通气,并被转移到医学重症监护室。计算机断层肺血管造影未发现肺栓塞的证据,尽管双侧弥漫性磨玻璃影伴间隔增厚、蜂窝状和牵引性支气管扩张明显。呼吸道病毒面板、COVID-19检测、真菌血清学和自身免疫/血管炎检查均为阴性。外部记录包括最近的支气管镜诊断,细胞学和培养结果不明显,肺功能检查显示限制性肺型和一氧化碳扩散能力严重降低,通气灌注扫描正常。我们给外部医生打了电话,证实该患者在过去十年中一直在服用大剂量胺碘酮(400毫克,每日两次),因为之前尝试减少或停用胺碘酮导致了他之前的心脏骤停。在多学科会议讨论后,由于怀疑有胺碘酮引起的肺毒性(AIPT),患者开始使用大剂量静脉注射类固醇。不幸的是,他的病情进一步恶化,他的家人最终选择了临终关怀。虽然AIPT的发生率低于10-15%,但该病例提醒人们注意与胺碘酮使用相关的潜在致命性肺部不良事件,并强调在用药期间密切监测多器官的必要性。仍然需要进一步研究阐明胺碘酮使用与相关肺毒性之间的剂量依赖和持续时间依赖关系,并确定易感危险因素。

Acute Interstitial Pneumonitis Secondary to Amiodarone 胺碘酮继发的急性间质性肺炎
Pub Date : 2021-01-01 DOI: 10.1164/ajrccm-conference.2021.203.1_meetingabstracts.a2147

INTRODUCTION-Amiodarone pulmonary toxicity risk is estimated to be around 1 to 5 percent, depending on risk factors like daily dose exceeding 400mg/day, intake of drug for more than two months, age above 60 years, duration of treatment of 6 to 12 months and prior history of lung disease. CASE -A 70-year-old white male with diabetes, chronic kidney disease, hypertension and obstructive sleep apnea, presented with atrial fibrillation with rapid ventricular response and acute hypoxic respiratory failure. SARS-CoV-2 RNA test was negative and pulmonary embolism was ruled out by CT Angiogram of chest. He underwent Transesophageal Echocardiogram guided cardioversion showing low normal left ventricular function and absence of left atrial appendage or thrombus. He was discharged on a anticoagulant and a diuretic. 2 weeks later he was readmitted with recurrent atrial fibrillation with rapid ventricular response. He was loaded with amiodarone intravenously and then transitioned to oral Amiodarone 400 mg orally twice daily. After 5 days he deteriorated requiring intubation for respiratory failure. CT Chest on day 5 of amiodarone administration showed new changes in form of bilateral ground glass attenuation, septal thickening and bilateral airspace consolidation when compared to previous admission. Laboratory findings included: white blood count 14000/uL, procalcitonin 0.28ng/ml, CRP 90 mg/L, BNP and negative respiratory viral panel. Flexible Bronchoscopy was performed which showed edematous airways and thin secretions. RESULT-Bronchoscopic alveolar lavage showed normal cell count, foamy macrophages, no malignant cells, and no growth on any culture. Biopsy was held given the acuity of his condition. His blood cultures, infectious work up and autoimmune workup was negative. Amiodarone was stopped and 60 mg oral prednisone was started for possible amiodarone induced acute interstitial pneumonitis and he responded well. He was extubated by day 10 and was on tapering oral steroid schedule for 6 months. CONCLUSION-Amiodarone pulmonary toxicity is usually recognized after 2-3 months of treatment, especially in patients taking dosages higher than 400 mg/day. This case is unique given the acute onset. The major hypothesis suggested include cytotoxic injury due to drug phospholipid complexes, alteration of phospholipid bilayer and free radical induced cellular injury and indirect Immunologic reaction. Currently there are no guidelines to prevent it. Acute pneumonitis although presents rarely, needs high index of suspicion for early diagnosis and immediate treatment with high dose intravenous steroids because of increased risk of mortality.
胺碘酮肺毒性风险估计约为1%至5%,取决于风险因素,如每日剂量超过400mg/天、服药超过两个月、年龄超过60岁、治疗持续时间6至12个月和既往肺部疾病史。病例- 70岁白人男性,患有糖尿病、慢性肾病、高血压和阻塞性睡眠呼吸暂停,表现为房颤伴快速心室反应和急性缺氧呼吸衰竭。SARS-CoV-2 RNA检测阴性,胸部CT血管造影排除肺栓塞。经食道超声心动图引导下的复律显示左心室功能低正常,左心房附件及血栓无。他出院时服用了抗凝血剂和利尿剂。2周后复发性心房颤动伴快速心室反应再次入院。患者静脉注射胺碘酮,然后改为口服胺碘酮400mg,每日口服两次。5天后病情恶化,因呼吸衰竭需要插管。胺碘酮给药第5天胸部CT显示双侧磨玻璃衰减、间隔增厚、双侧空域实变与入院前相比有新的变化。实验室检查结果:白细胞计数14000/uL,降钙素原0.28ng/ml, CRP 90 mg/L, BNP,呼吸道病毒阴性。行支气管镜检查发现气道水肿,分泌物稀薄。结果:支气管镜肺泡灌洗显示细胞计数正常,巨噬细胞呈泡沫状,未见恶性细胞,未见任何培养物生长。考虑到他的病情,我们进行了活组织检查。他的血液培养感染检查和自身免疫检查都呈阴性停用胺碘酮,开始口服强的松60mg,可能是胺碘酮引起的急性间质性肺炎,患者反应良好。患者于第10天拔管,口服类固醇减量治疗6个月。结论:胺碘酮肺毒性通常在治疗2-3个月后被发现,特别是在剂量高于400mg /d的患者中。考虑到急性发作,这个病例是独一无二的。提出的主要假说包括药物磷脂复合物引起的细胞毒性损伤、磷脂双分子层改变和自由基引起的细胞损伤和间接免疫反应。目前还没有预防的指导方针。急性肺炎虽然很少出现,但由于死亡风险增加,需要高怀疑指数进行早期诊断和立即使用大剂量静脉注射类固醇治疗。

Introduction-We present the case of a young male with constitutional symptoms thought to be consistent with community-acquired or COVID-19 pneumonia, who was instead found to have a history of vaping tetrahydrocannabinol (THC) and was diagnosed with EVALI (E-cigarette, or Vaping, Product Use-Associated Lung Injury). Case Presentation-21-year-old male college student presented to the hospital in July 2020 with a 2-week history of abdominal pain, vomiting, diarrhea, headache and generalized myalgias. More recently, he had a fever and dry cough associated with worsening shortness of breath. In the hospital, the patient was initially requiring minimal oxygen and was febrile to 102°F. Physical exam was consistent with a young, diaphoretic male with tachypnea who had bilateral basilar crackles on auscultation of lungs. Bloodwork revealed a leukocytosis of 19.2k/mm3, ferritin of 1081ng/mL and a CRP of 64mg/dL. An initial chest x-ray was consistent with bilateral interstitial markings. 2 days later, he was admitted to the intensive care unit since he was requiring high-flow nasal cannula. A Computed Tomography (CT) of the chest (Figure 1A, 1B) showed extensive peribronchial groundglass opacity with subpleural sparing. Complete respiratory viral panel, COVID-19, Tuberculosis, HIV and tickborne illnesses testing were all negative. By this time, the patient had been treated with antibiotics for presumed community-acquired pneumonia. The pulmonary service was consulted, and detailed social history-taking revealed that the patient had started vaping THC obtained from a less well-known brand, shortly before the onset of his symptoms. A bronchoscopy was performed which revealed evidence of anthracotic pigment present in distal airways. Bronchoalveolar lavage (BAL) ultimately revealed no evidence of infection or malignancy and showed foamy macrophages. Based on his presentation, a diagnosis of EVALI was made and the patient was started on intravenous corticosteroids. During the next 3 days, the patient's fever defervesced and his inflammatory markers down-trended. He was discharged home on room air with a corticosteroid taper. Discussion-Targeted history taking which addressed the specifics of the 'off-brand' or counterfeit THC vaping brands was key in revealing the etiology of the patient's symptoms and allowed the initiation of the correct treatment in a timely manner. Vitamin-E acetate has emerged as a potential common exposure among affected patients who use a variety of counterfeit products. Clinicians should be well versed with asking specific questions focused on type, duration and brand of products when EVALI is suspected.
我们报告了一名年轻男性的病例,他的身体症状被认为与社区获得性或COVID-19肺炎一致,但却发现他有吸食四氢大麻酚(THC)的病史,并被诊断为EVALI(电子烟或电子烟产品使用相关的肺损伤)。病例描述:21岁男大学生,于2020年7月入院,腹痛、呕吐、腹泻、头痛和全身肌痛2周。最近,他有发烧和干咳,并伴有呼吸急促加剧。在医院里,病人最初需要最低限度的氧气,体温高达102华氏度。体格检查符合一个年轻的,出汗的男性,呼吸急促,双侧基底肺听诊有裂纹。血检显示白细胞19.2k/mm3,铁蛋白1081ng/mL, CRP 64mg/dL。最初的胸部x光片与双侧间质标记一致。2天后,患者因需要高流量鼻插管而住进重症监护室。胸部计算机断层扫描(CT)(图1A, 1B)显示广泛的支气管周围毛玻璃影伴胸膜下保留。全呼吸道病毒、COVID-19、结核病、艾滋病毒和蜱传疾病检测均为阴性。此时,患者已经接受了抗生素治疗,疑似社区获得性肺炎。咨询了肺部服务部门,详细的社会病史显示,在症状出现前不久,患者开始吸食从一个不太知名的品牌获得的四氢大麻酚。支气管镜检查显示远端气道存在炭疽色素的证据。支气管肺泡灌洗(BAL)最终显示没有感染或恶性肿瘤的证据,并显示泡沫状巨噬细胞。根据他的报告,诊断为EVALI,并开始静脉注射皮质类固醇。在接下来的3天里,患者退烧,炎症指标下降。在皮质类固醇逐渐减少的情况下,他出院回家。讨论-针对“非品牌”或假冒四氢大麻酚电子烟品牌的具体情况进行有针对性的病史记录是揭示患者症状病因的关键,并允许及时开始正确的治疗。在使用各种假冒产品的受影响患者中,维生素e醋酸酯已成为一种潜在的常见暴露。当怀疑EVALI时,临床医生应精通询问具体问题,重点是产品的类型、持续时间和品牌。

Introduction: Crizotinib is an anaplastic lymphoma kinase (ALK) inhibitor used for advanced ALK-positive nonsmall cell lung cancer. It can rarely cause interstitial lung disease with a wide range of presentations from asymptomatic pulmonary radiological findings to fatal pneumonitis. Here, we present a case of rapid, acute hypoxemic respiratory failure due to crizotinib-induced pneumonitis. Case presentation: A 63-year-old man with a medical history of head and neck squamous cell cancer with metastasis to pulmonary parenchyma, pleura and mediastinal lymph nodes presented with dyspnea, fever and non-massive hemoptysis four days after initiation of crizotinib therapy. The patient was febrile, tachycardic, tachypneic and hypoxemic upon presentation. Laboratory investigations were unremarkable. Respiratory viral panel and reverse transcription-polymerase chain reaction for severe acute respiratory syndrome coronavirus 2 were negative. Further investigations including sputum, blood and urine culture were unrevealing. Chest radiographs rapidly progressed from baseline imaging to scattered patchy multifocal infiltrates. One day later, computerized tomography of the chest revealed rapidly progressing diffuse bilateral ground glass opacities. Despite empiric anti-microbial therapy, the patient's respiratory status deteriorated, and he was transferred to medical intensive care unit. He was pulsed with IV methylprednisolone 500mg twice a day for 3 days, followed by a slow taper for presumed pneumonitis secondary to crizotinib which led to a rapid improvement in his respiratory status. Discussion: ALK inhibitors are a relatively novel therapy for several malignancies and the side effects are not well known. In clinical trials, crizotinib was associated with interstitial lung disease in 2.4% of cases and presented at a median time of 20 days to 2 months after initiation. Management is challenging because there are no guidelines currently available for diagnosis and treatment of ALK inhibitor associated pneumonitis. Diagnosis generally requires a recent history of drug exposure, abnormal thoracic radiography, and clinical and/or radiologic improvement after discontinuation of the offending agent. Given their increasing use to treat various malignancies, it is imperative for clinicians to have a high index of suspicion for crizotinib-induced pneumonitis. A multidisciplinary approach will lead to rapid diagnosis and early treatment of this serious adverse events associated with this novel drug.
克唑替尼是一种间变性淋巴瘤激酶(ALK)抑制剂,用于晚期ALK阳性非小细胞肺癌。它很少引起间质性肺疾病,表现广泛,从无症状的肺部放射表现到致命的肺炎。在这里,我们提出一个病例快速,急性低氧性呼吸衰竭由于克唑替尼引起的肺炎。病例介绍:一名63岁男性,有头颈部鳞状细胞癌病史,并转移到肺实质、胸膜和纵隔淋巴结,在开始克唑替尼治疗4天后出现呼吸困难、发热和非大量咯血。患者就诊时出现发热、心动过速、呼吸过速和低氧血症。实验室检查无显著差异。呼吸道病毒面板和冠状病毒2型逆转录聚合酶链反应阴性。进一步的调查包括痰、血和尿培养都没有结果。胸部x线片迅速从基线成像发展为分散的斑片状多灶浸润。一天后,胸部电脑断层显示快速进展的弥漫性双侧磨玻璃影。尽管经验性的抗微生物治疗,病人的呼吸状况恶化,他被转移到医疗重症监护室。患者静脉注射甲基强的松龙500mg,每天两次,连续3天,随后因克唑替尼继发的疑似肺炎逐渐减少,导致呼吸状况迅速改善。讨论:ALK抑制剂是几种恶性肿瘤的一种相对较新的治疗方法,其副作用尚不清楚。在临床试验中,克里唑替尼在2.4%的病例中与间质性肺病相关,并且在开始治疗后的中位时间为20天至2个月。管理是具有挑战性的,因为目前没有诊断和治疗ALK抑制剂相关性肺炎的指南。诊断通常需要最近的药物暴露史,异常胸片,停药后的临床和/或放射学改善。鉴于它们越来越多地用于治疗各种恶性肿瘤,临床医生必须对克里唑替尼引起的肺炎有高度的怀疑。多学科方法将导致快速诊断和早期治疗与这种新药相关的严重不良事件。

Introduction: Eosinophilic pneumonia is a condition defined by eosinophilic infiltration of the lung parenchyma. Eosinophilic pneumonia is a known side effect of Dupilumab, a monoclonal antibody targeting the alpha chain of interleukin-4 (IL-4) that is used to treat moderate to severe atopic dermatitis and asthma by its inhibition of IL-4 and IL-13, which are key drivers in the TH2 response. We present a case of a patient presenting with eosinophilic pneumonia ten weeks after being started on Dupilumab. Case report: A 55-year-old female with history of asthma, bullous pemphigoid and chronic dermatitis who was started on Dupilumab (Dupixant) by her rheumatologist for treatment of her dermatitis and bullous pemphigoid ten weeks prior to presentation. Patient presented to the pulmonary clinic with four weeks history of worsening cough, shortness of breath, generalized body aches, lowgrade fevers, chills, chest pains and non-drenching night sweats. She had been treated by primary physician with a course of antibiotics without improvement in her symptoms. Outpatient chest computed tomography (CT chest) showed extensive bilateral reticular nodular opacities and scattered ground glass opacities (Panel A) for which she was admitted to the hospital for further evaluation. Patient was hypoxic and required 4 liters/minute oxygen by nasal cannula. Her laboratory testing showed normal leucocyte count 9.57 X 103/uL with eosinophilia of 17% (total eosinophilic count 17,000). Her immunoglobulin E was 2096 U/mL. Covid testing was negative. Rheumatologic workup was negative. Patient underwent fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) which showed 29% eosinophil count (Panel B) and was negative for bacterial and fungal cultures.Following BAL results, Dupilumab was discontinued and patient received single dose 60mg intravenous methylprednisone then oral prednisone 40 mg daily, resulting in rapid improvement in her symptoms, oxygen requirements and complete resolution of peripheral eosinophilia. She was discharged on oral prednisone taper. Discussion: Drug induced eosinophilic pneumonias are reported with medications such as non-steroidal anti-inflammatory drugs (NSAIDS), and antibiotics. There are very few described cases of Dupilumab-induced eosinophilic pneumonia in the medical literature. Eosinophilic pneumonia and eosinophilic conditions are listed side effects of Dupilumab which inhibits Th2 pathway by inhibiting IL-4 and IL-13 and should in theory decrease tissue eosinophilia, eosinophil degranulation, and reduce eosinophil survival. This case illustrates Dupilumab-induced eosinophilic pneumonia, suggesting that despite the drug's effect on Th2 cytokines, it can cause eosinophilic tissue infiltration and eosinophilia which if promptly identified and treated can lead to excellent outcomes. .
简介:嗜酸性粒细胞性肺炎是一种由肺实质嗜酸性粒细胞浸润引起的疾病。嗜酸性粒细胞性肺炎是Dupilumab的已知副作用,Dupilumab是一种靶向白细胞介素-4 (IL-4) α链的单克隆抗体,通过抑制IL-4和IL-13 (TH2反应的关键驱动因素)用于治疗中度至重度特应性皮炎和哮喘。我们提出了一个病例的病人呈现嗜酸性粒细胞肺炎十周后开始使用杜匹单抗。病例报告:一名55岁女性,有哮喘、大疱性类天疱疮和慢性皮炎病史,在就诊前10周由她的风湿病医生开始使用Dupilumab (Dupixant)治疗她的皮炎和大疱性类天疱疮。患者就诊于肺科门诊,有4周咳嗽加重、呼吸短促、全身疼痛、低烧、寒战、胸痛和非淋湿性盗汗病史。主治医生对她进行了一个疗程的抗生素治疗,但症状没有改善。门诊胸部计算机断层扫描(CT胸部)显示广泛的双侧网状结节性影和分散的磨玻璃影(A组),因此入院接受进一步检查。患者缺氧,需要4升/分钟的鼻插管供氧。实验室检查显示正常白细胞计数9.57 × 103/uL,嗜酸性粒细胞17%(嗜酸性粒细胞总计数17000)。免疫球蛋白E为2096 U/mL。新冠病毒检测呈阴性。风湿病检查呈阴性。患者行纤维支气管镜检查,支气管肺泡灌洗(BAL)显示嗜酸性粒细胞计数29% (B组),细菌和真菌培养均为阴性。BAL结果显示,停用杜匹单抗,患者接受单剂量60mg静脉注射甲基强的松,然后每天口服强的松40mg,导致患者的症状、氧气需求和周围嗜酸性粒细胞完全消退迅速改善。她口服强的松逐渐减少出院。讨论:药物性嗜酸性粒细胞肺炎的报道与药物,如非甾体抗炎药(NSAIDS)和抗生素。在医学文献中很少有dupilumab引起的嗜酸性肺炎的病例。嗜酸性肺炎和嗜酸性疾病是Dupilumab的副作用,Dupilumab通过抑制IL-4和IL-13抑制Th2途径,理论上应该减少组织嗜酸性粒细胞,嗜酸性粒细胞脱颗粒,降低嗜酸性粒细胞存活率。该病例说明了dupilumab诱导的嗜酸性肺炎,表明尽管药物对Th2细胞因子有作用,但它可以引起嗜酸性组织浸润和嗜酸性细胞增多,如果及时发现和治疗,可以导致良好的结果。

INTRODUCTION: Bleomycin is an antitumor agent most often used to treat Hodgkin lymphoma. The use of bleomycin is limited by potential for oxidative lung damage. Incidence correlates with cumulative dose, with most cases occurring with >400 international units (IU). Here we present an expository case of bleomycin-induced lung injury at an unusually low dose with additional important diagnostic considerations. CASE SUMMARY: A 37-year-old woman with a past medical history of HIV, Hodgkin's lymphoma, and renal failure requiring dialysis was evaluated for dyspnea and dry cough. The patient had completed three cycles of chemotherapy with ABVD (Doxorubicin, Bleomycin, Vinblastine, Dacarbazine). The cumulative dose of bleomycin was 32 IU. On examination, the patient was cachectic with mild bibasilar crackles noted on lung auscultation. The oxygen saturation was 97% while receiving supplemental oxygen at 2 liters per minute by nasal cannula. The CD4 count was 220. Chest radiography revealed patchy infiltrates scattered throughout both lungs not present on imaging five months prior. High-resolution CT showed widespread interstitial thickening and diffuse ground-glass opacities. Broad-spectrum antibiotics were started for suspected community acquired pneumonia to no effect. Further laboratory testing and bronchoalveolar lavage ruled out infectious etiology, including PCP and COVID19. Subsequent VATS and wedge resection was performed. Pathology demonstrated interstitial cellular infiltrate and fibrosis. A diagnosis of organizing pneumonia possibly related to bleomycin was made. Future treatment with bleomycin was discontinued. Systemic glucocorticoids were administered. Despite initial improvement, the patient's clinical course was complicated by hypoxemic respiratory failure, for which she underwent intubation and mechanical ventilation. She died on hospital day 30. No postmortem examination was performed. DISCUSSION: The diagnosis of bleomycin-induced lung injury is one of exclusion;often made within weeks of chemotherapy administration and rarely after six months. In this case, concurrent infection with HIV prolonged the time to diagnosis due to high clinical suspicion for atypical pneumonia. Moreover, the patient's limited renal function likely narrowed the chemotherapeutic safety window, given bleomycin is eliminated almost entirely by the kidney. Our case illustrates the importance of early consideration of this entity even at doses not routinely associated with toxicity. Upon diagnosis, treatment is immediate cessation of the causative agent followed by systemic glucocorticoids. The prognosis is grim, with most patients succumbing to respiratory failure within months of symptom onset.
博莱霉素是一种抗肿瘤药物,最常用于治疗霍奇金淋巴瘤。博莱霉素的使用受到潜在的氧化性肺损伤的限制。发病率与累积剂量有关,大多数病例发生在400国际单位(IU)。在这里,我们提出一个外源性病例博莱霉素诱导肺损伤在一个异常低的剂量与其他重要的诊断考虑。病例总结:一名37岁女性,既往有HIV、霍奇金淋巴瘤和肾衰竭需要透析的病史,因呼吸困难和干咳被评估。患者完成了三个周期的ABVD化疗(阿霉素、博来霉素、长春碱、达卡巴嗪)。博来霉素累积剂量为32iu。经检查,患者为病质,肺部听诊有轻度双基底动脉脆音。经鼻插管以每分钟2升的速度吸氧时,血氧饱和度为97%。CD4计数为220。胸片显示双肺散在的斑片状浸润,5个月前未见。高分辨率CT显示广泛间质增厚和弥漫性磨玻璃影。对疑似社区获得性肺炎使用广谱抗生素治疗,效果不明显。进一步的实验室检测和支气管肺泡灌洗排除了感染性病因,包括PCP和covid - 19。随后进行VATS和楔形切除术。病理表现为间质细胞浸润及纤维化。诊断为组织性肺炎,可能与博来霉素有关。随后停用博来霉素治疗。给予全身糖皮质激素。尽管最初有所改善,但患者的临床过程因低氧性呼吸衰竭而复杂化,为此她接受了插管和机械通气。她在医院的第30天死亡。没有进行尸检。讨论:博莱霉素引起的肺损伤的诊断是一种排除,通常在化疗给药后几周内诊断,很少在六个月后诊断。在本病例中,由于临床高度怀疑非典型肺炎,同时感染HIV延长了诊断时间。此外,鉴于博来霉素几乎完全被肾脏清除,患者有限的肾功能可能缩小了化疗的安全窗口。我们的病例说明了早期考虑这一实体的重要性,即使在通常与毒性无关的剂量下也是如此。诊断后,治疗是立即停止病原体,然后全身使用糖皮质激素。预后是严峻的,大多数患者死于呼吸衰竭在几个月内出现症状。
