Introduction: COVID-19 virus has been known to be a major cause of mortality secondary to cytokine storm and respiratory failure. Other manifestations include GI symptoms, loss of taste and smell and thromboembolism. Here we introduce a case of suspected COVID-19 induced viral myocarditis in an 86 year old woman. Case presentation: An 86-year-old female with no reported past medical history, not on daily medications, was brought in by ambulance after fall and unable to get up for many hours. On presentation, she was in mild distress due to left sided musculoskeletal pain, afebrile, tachycardic, tachypneic, and saturating at 93% on room air. Patient denied chest pain throughout her hospitalization. Tenderness in the left chest wall, left upper and lower extremities was elicited on physical examination. Labs obtained were significant for a creatine kinase of 37,000 IU/L and troponin I of 9.93ng/mL. EKG showed nonspecific T wave abnormalities, and prolonged QTC of 548ms. Chest x-ray showed multifocal pneumonia with no features suggestive of trauma. She was admitted to telemetry for further management of COVID-91 pneumonia and cardiac work up. Her troponin I peaked to 12.52ng/mL and she was treated with empiric intravenous heparin and aspirin. Echocardiogram shows global hypokinesis with left ventricular ejection fraction of 35-40%. Heart failure regimen with beta blocker and aldosterone receptor blocker were started. Rhabdomyolysis normalized with intravenous fluids. For COVID-19 pneumonia, she received dexamethasone and remdesivir and was weaned to 4L oxygen on discharge. Discussion:Viral myocarditis often results from a combination of direct viral injury and subsequent cellular immune activation. There is limited knowledge for COVID-19 associated viral myocarditis;most documented cases are from existing case reports, where most patients are male, and under the age of 70 years. Diagnosis is often challenging, as endomyocardial biopsy is often forgone in the setting of the ongoing pandemic and increased infection risk. Treatment for viral myocarditis involves heart failure management followed by directed therapy based on suspected etiology. Lymphocytic myocarditis, as seen in the setting of COVID-19, would typically involve immunosuppression in the form of glucocorticoids and intravenous immunoglobulin;although these regimens have yet to be extensively studied in COVID-19 associated myocarditis. As literature on this infection is rapidly evolving, it is vital to recognize and document suspected cases. This case helps to establish presentation of COVID-19 induced viral myocarditis and facilitate future understanding and raises awareness of this extrapulmonary presentation.
导言:已知COVID-19病毒是细胞因子风暴和呼吸衰竭继发死亡的主要原因。其他表现包括胃肠道症状、味觉和嗅觉丧失以及血栓栓塞。我们在此报告一例疑似COVID-19引起的病毒性心肌炎,患者为86岁女性。病例介绍:86岁女性,无既往病史报告,无日常用药,跌倒后被救护车送来,数小时无法起床。入院时,她因左侧肌肉骨骼疼痛,发热,心动过速,呼吸过速,室内空气饱和度达93%而出现轻微窘迫。病人在住院期间否认胸痛。体格检查发现左胸壁、左上肢和下肢有压痛。实验结果表明,肌酸激酶为37,000 IU/L,肌钙蛋白I为9.93ng/mL。心电图显示非特异性T波异常,QTC延长548ms。胸部x线显示多灶性肺炎,无外伤征象。她接受了遥测治疗,以进一步治疗COVID-91肺炎和心脏检查。她的肌钙蛋白I峰值为12.52ng/mL,并给予经验性静脉注射肝素和阿司匹林治疗。超声心动图显示全身运动不足,左室射血分数35-40%。开始使用-受体阻滞剂和醛固酮受体阻滞剂治疗心力衰竭。横纹肌溶解经静脉输液恢复正常。因COVID-19肺炎,她接受地塞米松和瑞德西韦治疗,出院时断奶至4L吸氧。讨论:病毒性心肌炎通常是由直接的病毒损伤和随后的细胞免疫激活共同引起的。对COVID-19相关病毒性心肌炎的了解有限;大多数记录的病例来自现有病例报告,其中大多数患者为男性,年龄在70岁以下。诊断通常具有挑战性,因为在持续的大流行和感染风险增加的情况下,经常放弃心肌膜活检。病毒性心肌炎的治疗包括心衰管理,随后根据疑似病因进行定向治疗。在COVID-19的情况下,淋巴细胞性心肌炎通常涉及糖皮质激素和静脉注射免疫球蛋白的免疫抑制,尽管这些方案尚未在COVID-19相关心肌炎中进行广泛研究。由于关于这种感染的文献正在迅速发展,识别和记录疑似病例至关重要。本病例有助于确定COVID-19诱导的病毒性心肌炎的表现,促进未来的理解,并提高对这种肺外表现的认识。

A 61-year old man was admitted to the intensive care unit for acute respiratory distress syndrome after presenting with four days of dyspnea. Chest imaging revealed diffuse ground glass opacities and he was found to be positive for SARS-CoV-2 infection. His hospital course was complicated by sequelae of coronavirus disease 2019 (COVID-19) including prolonged mechanical ventilation and renal failure requiring hemodialysis. He never received steroids or other immunosuppressive therapy. After one month, he developed new fevers and thick respiratory secretions. Repeat SARS-CoV-2 PCR at this time was negative. Repeat chest imaging revealed a new right upper lobe cavitary lesion. Differential diagnosis at that time included a developing lung abscess and invasive fungal infection. Tracheal cultures and non-bronchoscopic alveolar lavages were collected and serum galactomannan was sent. Due to ongoing need for mechanical ventilation and persistent secretions, empiric broad spectrum antibiotics and amphotericin B (to include mucormycosis coverage) were started. Cultures initially revealed mold finalized as Aspergillus fumigatus. Antifungal therapy was tailored to voriconazole. His fevers ultimately resolved, and he was weaned to minimal ventilator settings in preparation for tracheostomy. Invasive pulmonary aspergillosis is a serious infection that can cause severe systemic dysfunction. On imaging, aspergillosis can appear as solitary or multiple pulmonary nodules or masses with a halo, or reverse halo sign. Peripheral areas of consolidation, with or without cavitation, with adjacent pleural thickening and potentially direct invasion into the adjacent chest wall may be seen in advanced cases. Co-infection with aspergillosis in COVID-19 is a newly recognized phenomenon. There is ongoing discussion regarding appropriate evaluation and empiric, perhaps even prophylactic, use of antifungal therapy. Our case was diagnosed after presumed resolution of SARS-CoV-2 infection bringing to question the role for routine fungal disease evaluation in so-called recovered individuals with on-going respiratory compromise.
一名61岁男子在出现4天呼吸困难后因急性呼吸窘迫综合征入住重症监护病房。胸部影像学显示弥漫性磨玻璃混浊,他被发现为SARS-CoV-2感染阳性。他的住院过程因2019冠状病毒病(COVID-19)的后遗症而变得复杂,包括机械通气时间延长和需要血液透析的肾功能衰竭。他从未接受过类固醇或其他免疫抑制治疗。一个月后,他又开始发烧,呼吸道分泌物浓厚。重复SARS-CoV-2 PCR结果为阴性。胸部重复显像显示新的右上肺叶空洞病变。当时的鉴别诊断包括发展中的肺脓肿和侵袭性真菌感染。收集气管培养和非支气管镜肺泡灌洗,并送血清半乳甘露聚糖。由于持续需要机械通气和持续分泌物,开始使用经验性广谱抗生素和两性霉素B(包括毛霉病的覆盖范围)。培养最初显示霉菌最终确定为烟曲霉。抗真菌治疗针对伏立康唑。他的发烧最终消退,并断奶至最低呼吸机设置,为气管切开术做准备。侵袭性肺曲霉病是一种严重的感染,可引起严重的全身功能障碍。影像学上,曲霉病可表现为单发或多发肺结节或团块伴晕状或反晕状征象。晚期病例可见周围实变,伴或不伴空化,伴邻近胸膜增厚,并可能直接侵犯邻近胸壁。COVID-19与曲霉病合并感染是一种新认识的现象。关于抗真菌治疗的适当评估和经验性,甚至是预防性使用,正在进行讨论。我们的病例是在假定SARS-CoV-2感染解决后诊断出来的,这对在持续呼吸损害的所谓康复个体中进行常规真菌疾病评估的作用提出了质疑。

Mycobacterium kansasii is a nontuberculous mycobacterium which leads to a chronic pulmonary infection that resembles pulmonary tuberculosis. Symptoms of pulmonary infection with M kansasii may include cough, sputum production, weight loss, breathlessness, chest pain, hemoptysis and fever or sweats.The paper presents the case of a 30-year-old woman, confirmed with moderate SARS-COV2 infection at a county hospital and transferred to "Marius Nasta" Institute for Pneumology for specialty treatment. At admission, the CT exam reveals multiple "tree in bud" lesions and cavity lesions located at the RUL level. Bacteriological examinations for the genus mycobacterium were initially negative, but from the bronchial aspirate, the bacteriological examination was BAAR positive. Genetic testing confirmed mycobacterium infection. Resistance to H, R was not detected. According to the national protocol, antibiotic treatment is initiated with Isoniazid, Rifampicin, Ethambutol and Pyrazinamide. The patient tolerated the treatment well throughout the hospitalization period, as there were no interactions between the treatment for SARS-COV2 and the antibiotic one. Due to the favorable evolution, the patient is discharged one month after starting treatment. As recommendations, the patient must present herself at the territorial TB clinic, in order to continue the antibiotic treatment for up to 6 months.At two months, the culture shows infection with mycobacterium kansassi, thus the treatment is modified by administering Rifampicin, Etambutol and Azithromycin. Following the administration of the new treatment, the lung lesions show regression. In the case of mycobacterium kansassi infections, the treatment will be continued for up to 12 months. The evolution of M. kansassi infection may be influenced by various factors, but in this case the moderate SARS-COV2 infection, cured in 3 weeks, did not influence the favourable evolution. Also, the absence of shortness of breath, as well as the compliance and absence of treatment resistance were keen factors in the evolution under treatment.In conclusion, the patient was initially admitted to the hospital for a moderate COVID-19 infection. The routine CT exam was also suggestive for a possible other pathology, and follow-up tests and examinations led to the discovery of an infection with M. kansassi. The SARS-COV-2 infection had favourable evolution under treatment and was cured in 3 weeks, but the treatment for M. kansassi is long-term and may have effects on the patients' psychology, as well as by the presence of adverse reactions, not following the treatment can be fatal with death occurring in 50% of cases.
堪萨斯分枝杆菌是一种非结核性分枝杆菌,可导致类似肺结核的慢性肺部感染。肺部感染堪萨斯分枝杆菌的症状可能包括咳嗽、咳痰、体重减轻、呼吸困难、胸痛、咯血、发烧或出汗。本文报告了一名30岁妇女的病例,她在县医院确诊为中度SARS-COV2感染,并转移到“马吕斯纳斯塔”肺炎研究所接受专科治疗。入院时,CT检查显示多发“芽状树”病变和位于RUL水平的空洞病变。分枝杆菌属细菌学检查最初为阴性,但从支气管吸入,细菌学检查BAAR阳性。基因检测证实感染分枝杆菌。未检出对H、R的耐药性。根据国家方案,抗生素治疗开始使用异烟肼、利福平、乙胺丁醇和吡嗪酰胺。患者在整个住院期间耐受性良好,因为SARS-COV2治疗与抗生素治疗之间没有相互作用。由于病情进展良好,患者在开始治疗一个月后出院。根据建议,患者必须亲自到地区结核病诊所就诊,以便继续抗生素治疗长达6个月。在两个月时,培养物显示出堪萨斯分枝杆菌感染,因此治疗方法改为给予利福平、依坦丁醇和阿奇霉素。在接受新疗法后,肺部病变出现消退。在堪萨斯分枝杆菌感染的情况下,治疗将持续长达12个月。肯萨西支原体感染的演变可能受到多种因素的影响,但在本病例中,3周治愈的中度SARS-COV2感染并未影响有利的演变。无呼吸短促、依从性及无治疗抵抗是治疗进展的重要因素。总之,患者最初因中度COVID-19感染而入院。常规CT检查也提示可能有其他病理,随后的检查和检查发现了堪萨斯分枝杆菌感染。SARS-COV-2感染在治疗中有良好的进展,并在3周内治愈,但对堪萨斯分枝杆菌的治疗是长期的,可能对患者的心理产生影响,并且由于存在不良反应,不接受治疗可能是致命的,50%的病例发生死亡。

Introduction: COVID-19 has a variable clinical presentation ranging from flu-like symptoms to respiratory failure. Most patients have a mild form of disease and often recover at home over a period of weeks. For some, the highest morbidity of COVID-19 may not be associated with the acute phase of the disease, but rather the longstanding post-viral pulmonary fibrosis. Case Description: A 49-year-old man with a past medical history of coronary artery disease, obstructive sleep apnea, hypertension, and type two diabetes mellitus presented to the emergency department with a four-day history of fever, nausea, and diarrhea. He denied cough or dyspnea. Chest radiograph revealed bibasilar ground glass opacifications. He was positive for severe acute respiratory syndrome coronavirus 2 by polymerase chain reaction testing. His oxygen saturation was 95% on room air and he was discharged home without treatment. Over the following days, he developed a dry cough and mild dyspnea, but he did not desaturate on room air. He was prescribed a short course of steroids by his outpatient pulmonologist. He gradually improved over the course of two weeks and he was never hospitalized. Computed tomography (CT) of the chest 10 weeks after diagnosis revealed bilateral patchy ground glass opacities in all lobes and interstitial components with architectural distortion in the lower lobes (Image 1). A pulmonary function test performed 12 weeks after diagnosis showed an FVC 83%, FEV1 85%, TLC 75%, RV 37%, and DCLO 88%. The patient continued to experience mild dyspnea with exertion 2 months after the resolution of the infection. Conclusion: Pulmonary fibrosis is not a post-viral phenomenon limited to severe cases of COVID-19 and can occur following mild presentations managed at home. Thus far, risk factors for the development of pulmonary fibrosis secondary to COVID-19 have been reported to be advanced age, disease severity, length of intensive care unit stay, smoking, and alcoholism. Our case report calls for a re-evaluation of these risk factors. While pharmaceutical treatments are typically only administered to hospitalized patients, there may be basis for treating mild cases with the intent of preventing post-viral pulmonary fibrosis. Further, outpatient clinicians may consider monitoring for changes in pulmonary architecture with pulmonary function tests or high-resolution CT scans in all recovered COVID-19 patients regardless of symptom severity.
简介:COVID-19的临床表现多种多样,从流感样症状到呼吸衰竭。大多数患者的病情较轻,通常在家中几周后就能康复。对一些人来说,COVID-19的最高发病率可能与疾病的急性期无关,而是与长期存在的病毒后肺纤维化有关。病例描述:一名49岁男性,既往有冠状动脉疾病、阻塞性睡眠呼吸暂停、高血压和2型糖尿病病史,因发热、恶心和腹泻4天就诊于急诊科。他否认咳嗽或呼吸困难。胸片显示双基底动脉磨玻璃混浊。聚合酶链反应检测为严重急性呼吸综合征冠状病毒2型阳性。他的血氧饱和度在室内空气中为95%,他未经治疗就出院回家了。在接下来的几天里,他出现干咳和轻度呼吸困难,但他没有在室内空气中去饱和。门诊肺科医生给他开了一个短期的类固醇疗程。在两周的时间里,他逐渐好转,从未住院。诊断后10周的胸部计算机断层扫描(CT)显示双侧所有肺叶和间质成分呈斑片状磨玻璃影,下肺叶有结构扭曲(图1)。诊断后12周进行的肺功能检查显示FVC 83%, FEV1 85%, TLC 75%, RV 37%, DCLO 88%。患者在感染消退2个月后继续出现轻度呼吸困难。结论:肺纤维化并不局限于COVID-19重症病例的病毒后现象,在家中处理轻度症状后也可能发生。到目前为止,据报道,COVID-19继发性肺纤维化发展的危险因素包括高龄、疾病严重程度、重症监护病房住院时间、吸烟和酗酒。我们的病例报告要求重新评估这些风险因素。虽然药物治疗通常只适用于住院患者,但治疗轻度病例以预防病毒后肺纤维化可能是有依据的。此外,门诊临床医生可以考虑通过肺功能检查或高分辨率CT扫描监测所有康复的COVID-19患者的肺结构变化,无论症状严重程度如何。

Introduction: Cavitary lesions have a very broad differential diagnosis. Some case studies have shown COVID19 to cause cavitary lesions1,2 and others have shown COVID19 to cause pneumothorax3. We describe a case report of a young man with no significant past medical history who was hospitalized for COVID19 pneumonia and was subsequently developed a pneumothorax. Case Report: A 39-year-old male presented to the hospital for acute onset shortness of breath. On admission, he was found to have right-sided pneumothorax and a pigtail catheter was placed with a proper expansion of the right lung. Approximately one month previously, he had been admitted for mild COVID19 pneumonia and successfully treated with dexamethasone and was discharged home with stable condition.On further evaluation, chest CT revealed multiple cavitary lesions with one large cavitation in the inferior right upper lobe with prominent mediastinal and hilar nodes. Quantiferon gold, AFB x3, and mycobacterium complex PCR were all negative. Fungitell, 1-3 B-D gluten, and coccioides antibodies were also negative. The patient had no other suggestive features to warrant vasculitis or malignancy evaluation. Discussion:The importance of this case is recognizing the late sequela of COVID19 pneumonia such as cavitary lesions and pneumothorax as seen with our patient. Some studies showed the development of pneumothorax associated with COVID19 but no previous studies showed the development of these findings in a patient without any past pulmonary history3. We attributed the development of cavitary lesions to covid19 and subsequently, because of that, the patient developed pneumothorax. Conclusion: It is important to consider the long term sequela of COVID19 pneumonia especially in those we consider to have mild disease. It is important to minimize potential severe consequences such as pneumothorax which occurred due to intense coughing as seen with our patient.
简介:空洞性病变具有非常广泛的鉴别诊断。一些病例研究表明,covid - 19会导致空洞病变1,2,其他病例研究表明,covid - 19会导致气胸3。我们描述了一例无明显既往病史的年轻男性因covid - 19肺炎住院并随后发展为气胸的病例报告。病例报告:一名39岁男性因急性起病呼吸短促而就诊。入院时,他被发现有右侧气胸,在适当扩张右肺的情况下放置了一根细尾导管。大约一个月前,他因covid - 19轻度肺炎入院,地塞米松治疗成功,出院后病情稳定。胸部CT示多发空腔病变,右下上叶1个大空腔病变,纵膈淋巴结和肺门淋巴结突出。定量铁金、AFB x3、分枝杆菌复合体PCR均为阴性。真菌、1-3 B-D谷蛋白和球虫抗体也呈阴性。患者没有其他提示特征,以保证血管炎或恶性评价。讨论:本病例的重要性在于认识到我们的患者所见的covid - 19肺炎的晚期后遗症,如空洞病变和气胸。一些研究显示与covid - 19相关的气胸的发展,但之前没有研究显示在没有任何肺部病史的患者中出现这些发现3。我们将空洞病变的发展归因于covid - 19,因此,患者出现了气胸。结论:考虑covid - 19肺炎的长期后遗症是重要的,特别是我们认为病情轻微的患者。重要的是要尽量减少潜在的严重后果,如气胸,这是由于我们的病人剧烈咳嗽造成的。

Since the onset of the coronavirus disease 2019 (COVID-19) due to the SARS-CoV-2 virus, recommendations for diagnostics and therapeutics have rapidly evolved. The World Health Organization recommends nucleic acid amplification testing (NAAT) such as reverse transcriptase PCR (RT-PCR) as the standard for COVID-19, with a sensitivity of 95%. However, many factors can affect the results including timing of test, specimen quality, specimen handling, pooling specimens, and other technical reasons, resulting in false negatives. The case below describes a patient with a clinical presentation concerning for COVID-19 despite three negative RT-PCR tests and highlights the importance of treating patients based on their entire clinical impression rather than a single data point. A 53-year-old Hispanic male with no medical history presented to the hospital with 4 days of dyspnea and cough. He was admitted to the intensive care unit with acute hypoxemic respiratory failure requiring heated high flow nasal cannula. No associated fever, myalgias, anosmia, diarrhea, and he denied any known ill contacts, inhalation exposures or prior smoking history. Laboratory workup was notable for thrombocytosis, lymphopenia, elevated ferritin, C-reactive protein, D-dimer and lactate dehydrogenase as commonly seen with COVID-19. Infectious screen resulted with negative SARS-CoV-2 PCR by nasal swab, negative respiratory viral panel, negative HIV PCR, and negative fungal pneumonia screen. Imaging showed bilateral ground-glass opacities consistent with multifocal pneumonia (figure). He was started on a 5-day course of antibiotics for community acquired pneumonia and given high suspicion for COVID-19 pneumonia was started on dexamethasone 6mg daily with a plan to repeat SARS-CoV-2 testing. Repeat SARS-CoV-2 PCR was negative on hospital day 2 and 4 but SARS-CoV-2 antibody was positive on hospital day 6 (10 days after symptom onset). Given the positive antibody test and clinical course consistent with COVID-19 pneumonia, he was continued on dexamethasone for a total of 10 days, completed a 5-day course of remdesivir, and received 1 unit of convalescent plasma with clinical improvement. He was discharged home on hospital day 15 with supplemental oxygen. With increasing rates of infection with the SARS-CoV-2 virus, it becomes critically important to quickly and accurately diagnose patients. While RT-PCR has high sensitivity, there are still several factors that affect the accuracy and may result in false-negative results with potential implications such as delay in treatment and failure to quarantine. This case highlights the importance to treat patients based on a comprehensive clinical impression rather than a single test result.
自SARS-CoV-2病毒引起的2019冠状病毒病(COVID-19)发病以来,诊断和治疗方法的建议迅速发展。世界卫生组织推荐逆转录酶PCR (RT-PCR)等核酸扩增检测(NAAT)作为新冠病毒的检测标准,灵敏度为95%。然而,许多因素会影响结果,包括测试时间,标本质量,标本处理,汇集标本和其他技术原因,导致假阴性。下面的病例描述了一名临床表现与COVID-19有关的患者,尽管三次RT-PCR检测均为阴性,并强调了根据患者的整个临床印象而不是单一数据点治疗患者的重要性。一名53岁西班牙裔男性,无病史,以4天呼吸困难和咳嗽就诊。他因急性低氧性呼吸衰竭被送进重症监护室,需要加热高流量鼻插管。无相关发热、肌痛、嗅觉丧失、腹泻,否认有任何已知的疾病接触、吸入暴露或既往吸烟史。实验室检查发现血小板增多、淋巴细胞减少、铁蛋白、c反应蛋白、d -二聚体和乳酸脱氢酶升高,这些都是COVID-19常见的症状。感染筛查结果为SARS-CoV-2鼻拭子PCR阴性、呼吸道病毒检测阴性、HIV PCR阴性、真菌性肺炎筛查阴性。影像学显示双侧磨玻璃混浊,符合多灶性肺炎(图)。给予5天社区获得性肺炎抗生素治疗,高度怀疑为新型冠状病毒肺炎,每日给予地塞米松6mg,并计划重复进行新冠病毒检测。重复SARS-CoV-2 PCR在住院第2天和第4天呈阴性,但在住院第6天(症状出现后10天)呈阳性。鉴于抗体检测阳性且临床病程与COVID-19肺炎相符,患者继续地塞米松治疗共10天,完成5天疗程的瑞德西韦治疗,临床好转后接受1单位恢复期血浆治疗。他在住院第15天出院,并补充了氧气。随着SARS-CoV-2病毒感染率的上升,快速准确地诊断患者变得至关重要。虽然RT-PCR具有很高的灵敏度,但仍有几个因素会影响准确性,并可能导致假阴性结果,从而造成治疗延误和未能隔离等潜在影响。这个病例强调了根据全面的临床印象而不是单一的检查结果来治疗患者的重要性。

Introduction: Co-infections in hospitalized patients are associated with higher mortality. The rate of co-infection in COVID-19 at the time of hospitalization is estimated at around 10%, but the long-term impact of SARS-CoV-2 on the immune system following the initial infectious period is unknown. Here we describe the case of a previously healthy patient hospitalized with coccidioides pulmonary infection following mild COVID-19 disease. Case: A 52-year-old man with no significant past medical history presented to the hospital with worsening non-productive cough, left-sided pleuritic chest pain, fevers, chills and sweats. Four weeks prior to presentation, he was diagnosed with COVID-19 pneumonia. He experienced respiratory symptoms for 7 days and then made a full recovery. Ten days later, he developed a new cough. He was found to have a new infiltrate on chest radiograph and was treated with two courses of oral antibiotics without improvement. CT chest was done and found to be concerning for a "fungal ball" and he subsequently presented to Jacobs Medical Center. He denied occupational exposures or smoking history. He was born in Ohio, and moved to California at age 3. Chest CT showed a left lower lobe mass-like consolidation with central necrosis, trace pleural effusion, and mediastinal lymphadenopathy. Initial laboratory evaluation revealed a leukocytosis to 17 that was neutrophil predominant. Over the next 5 days, his absolute eosinophil count climbed from 400 to 1100. COVID-19 PCR testing at the time of admission was negative. During bronchoscopy, there were two submucosal nodules in the distal trachea and left mainstem bronchus and bronchoalveolar lavage (BAL) was obtained from the left lower lobe. Cytopathic review of the BAL fluid revealed acute inflammation and spherules consistent with Coccidioides immitis. The BAL cell count revealed 21% eosinophils and fungal cultures grew coccidioides. Coccidioides IgM was positive, while IgG was negative. He was initiated on fluconazole therapy with rapid resolution of fevers and improvement in his cough and pleuritic chest pain. Discussion: This is a classic presentation of acute coccidioidomycosis infection involving a lobar necrotizing pneumonia, peripheral and BAL eosinophilia, bronchial submucosal nodules, positive serum IgM antibodies, fungal cultures, and cytopathologic exam. This case highlights the possibility that patients with COVID-19 infection are at increased risk of developing subsequent infections. It will be important for providers to remain vigilant for opportunistic infections at the time of presentation and in the period following COVID-19 infection.
住院患者的合并感染与较高的死亡率相关。住院时合并感染COVID-19的比例估计约为10%,但SARS-CoV-2在初始感染期后对免疫系统的长期影响尚不清楚。在这里,我们描述了一个先前健康的患者在轻度COVID-19疾病后因球虫肺部感染住院的病例。病例:一名52岁男性,无明显既往病史,因非咳加重、左侧胸膜炎性胸痛、发热、寒战和出汗就诊。在发病前四周,他被诊断患有COVID-19肺炎。他经历了7天的呼吸道症状,然后完全康复。十天后,他又咳嗽了。他在胸片上发现有新的浸润,并接受了两个疗程的口服抗生素治疗,但没有好转。胸部做了CT,发现有一个“真菌球”,随后他被送到了雅各布斯医疗中心。他否认职业暴露或吸烟史。他出生在俄亥俄州,3岁时搬到加州。胸部CT显示左下肺叶肿块样实变伴中央坏死,胸膜积液及纵隔淋巴结病变。最初的实验室评估显示白细胞增多至17,中性粒细胞为主。在接下来的5天里,他的绝对嗜酸性粒细胞计数从400上升到1100。入院时COVID-19 PCR检测为阴性。支气管镜检查发现远端气管及左主干支气管黏膜下结节2个,左下叶支气管肺泡灌洗(BAL)。BAL液的细胞病理学检查显示急性炎症和球虫炎一致的球粒。BAL细胞计数显示21%的嗜酸性粒细胞和真菌培养的球虫增多。球虫IgM阳性,IgG阴性。他开始使用氟康唑治疗,发烧迅速消退,咳嗽和胸膜炎性胸痛得到改善。讨论:这是一个典型的急性球虫菌病感染,包括大叶坏死性肺炎,外周和BAL嗜酸性粒细胞增多,支气管粘膜下结节,血清IgM抗体阳性,真菌培养和细胞病理学检查。该病例凸显了COVID-19感染患者发生后续感染的风险增加的可能性。提供者在就诊时和COVID-19感染后的一段时间内对机会性感染保持警惕非常重要。

Introduction: COVID-19 has a wide range of clinical manifestations involving multiple organ systems. There have been a few cases in the literature that demonstrate the association between COVID-19 and hypertriglyceridemia in the setting of treatment with tocilizumab. We report, to our knowledge, the first known series of patients with critical illness resulting from COVID-19, who developed severe hypertriglyceridemia in the absence of treatment with tocilizumab. Description: Case 1: A 57-year-old male with end-stage renal disease, diabetes mellitus, and hypertension was admitted to the hospital with worsening shortness of breath due to COVID-19. He was initially managed with conservative measures including supplemental oxygen on the medical floor but required transfer to the ICU for worsening hypoxemia necessitating invasive mechanical ventilation. The patient developed a lipemic serum on hospital day 8. His triglyceride level was noted to be 3160mg/dl, with a baseline level of 224mg/dl 1-year prior. Patient deteriorated rapidly and expired before appropriate treatment measures for his hypertriglyceridemia could be implemented. Case 2: A 73-year-old male with pulmonary fibrosis and coronary artery disease was admitted to the hospital with shortness of breath due to COVID-19. He was managed with remdesivir and dexamethasone on the medical floor, but deteriorated further and required invasive mechanical ventilation and continuous renal replacement therapy. Patient developed lipemic serum on hospital day 19 and was found to have a triglyceride level of 1757mg/dl, with a baseline level of 173mg/dl 1-year prior. Patient was started on an insulin infusion but continued to deteriorate and expired on hospital day 20. Case 3: A 47-year-old hypertensive male patient was admitted with worsening shortness of breath due to COVID-19. He was initially treated with dexamethasone and supplemental oxygen but deteriorated and required invasive mechanical ventilation as well as continuous renal replacement therapy. He was noted to have a lipemic serum on hospital day 14 and was found to have a triglyceride level of 945mg/dl. Patient was managed with an insulin infusion with subsequent improvement in his levels. Patient had a prolonged hospitalization and required tracheostomy but has since made a full recovery including the recovery of his renal function, and has returned to work. Image below shows the lipemic serum of our patient: Discussion: These cases suggest an association between severe COVID-19 and hypertriglyceridemia in the absence of treatment with tocilizumab. Further studies are needed to determine whether this association truly exists, its implications on prognosis, and to determine optimal management strategies.
新冠肺炎临床表现广泛,涉及多器官系统。文献中有一些病例表明,在使用托珠单抗治疗的情况下,COVID-19与高甘油三酯血症之间存在关联。据我们所知,我们报告了第一批已知的由COVID-19引起的危重疾病患者,他们在没有使用托珠单抗治疗的情况下发生了严重的高甘油三酯血症。病例1:一名57岁男性,患有终末期肾病、糖尿病和高血压,因COVID-19导致呼吸急促加重而入院。他最初采取保守措施,包括在医疗楼层补充氧气,但由于低氧血症恶化,需要有创机械通气,他被转移到ICU。患者在住院第8天出现血脂升高。他的甘油三酯水平被记录为3160mg/dl,一年前的基线水平为224mg/dl。患者病情迅速恶化,在采取适当的治疗措施前死亡。病例2:73岁男性,合并肺纤维化、冠状动脉疾病,因新冠肺炎致呼吸短促入院。他在医疗楼接受了瑞德西韦和地塞米松治疗,但病情进一步恶化,需要有创机械通气和持续肾脏替代治疗。患者在住院第19天出现血脂升高,发现甘油三酯水平为1757mg/dl, 1年前的基线水平为173mg/dl。患者开始注射胰岛素,但病情持续恶化,于住院第20天死亡。病例3:47岁男性高血压患者因新型冠状病毒感染呼吸急促加重入院。他最初使用地塞米松和补充氧气治疗,但病情恶化,需要有创机械通气和持续肾脏替代治疗。在住院第14天,他被注意到有血脂,发现甘油三酯水平为945mg/dl。患者接受胰岛素输注治疗,随后胰岛素水平有所改善。患者长期住院并需要气管切开术,但此后已完全康复,包括肾功能恢复,并已重返工作岗位。讨论:这些病例提示在未使用托珠单抗治疗的情况下,严重的COVID-19与高甘油三酯血症之间存在关联。需要进一步的研究来确定这种关联是否真的存在,它对预后的影响,并确定最佳的管理策略。

INTRODUCTION: due to the fact that lung disease due to SARS COV 2 infection is of recent appearance and the lack of knowledge about its natural history, it is not clear the moment of adequate follow-up by diagnostic images, this being suggested after 3 months of the onset of the symptoms according to the evolution of the patient. We present the variation of image findings of a patient with severe COVID-19 pneumonia. DESCRIPTION:we present the case of a 56-year-old male patient who required initial hospitalization of 14 days because of symptoms secondary to multilobar severe pneumonia due to SARS-COV-2 infection with initial tomographic findings of classic pattern given by ground glass opacities of subpleural distribution predominantly in the lower lobes. The patient was discharged with low flow oxygen supplementation and attended the pulmonology consultation a month later reporting improvement in dyspnea with medical research council score grade 1 and complete withdrawal of oxygen support. A control chest computed tomography was taken 6 weeks since initial evaluation reporting subpleural bullae of recent appearance in the upper and lower right lobe with diameters of up to 80 mm. It was also described a small residual laminar pneumothorax adjacent to the lingula with pleural effusion with apparent septae. Given these findings, an intervention by thoracic surgery was requested who decided to schedule a surgical procedure and performed a new control image corresponding to 8 weeks from the initial one with findings of complete and spontaneous resolution of the pneumothorax as well as the pleural effusion although persistence of the bullas. It was decided there was not required further interventions and patient was discharged from follow-up.DISCUSSION: SARS-CoV2 infection manifests itself in different patterns of lung damage and can have long term pulmonary sequelae that are only identified with judicious and strict follow-up during the first months after infection. Nevertheless, the British Thoracic Society (BTS) has recommended the first image follow-up to be preformed after 3 months of the initial symptoms because of the high incidence of image alterations in that period of time and lesser probability of occult malignancy. This case described a rare presentation of lung damage with equally spontaneous resolution of the complications confirming the timeframe proposed by the BTS.
由于SARS冠状病毒2感染引起的肺部疾病是最近才出现的,并且对其自然史缺乏了解,因此不清楚何时通过诊断图像进行充分的随访,建议根据患者的病情发展在症状出现3个月后进行随访。我们提出了一名重症COVID-19肺炎患者的图像发现的变化。描述:我们报告了一名56岁男性患者,由于SARS-COV-2感染引起的多叶严重肺炎继发症状,最初需要住院14天,最初的断层扫描结果为典型的胸膜下分布的磨玻璃浊影,主要分布在下叶。患者在低流量补氧下出院,一个月后接受肺科咨询,报告呼吸困难改善,医学研究委员会评分为1级,完全停止氧气支持。首次评估报告右上叶和右下叶胸膜下大泡,直径达80mm, 6周后进行对照胸部计算机断层扫描。它也描述了一个小残留层状气胸邻近舌,胸膜积液和明显的间隔。考虑到这些发现,我们要求通过胸外科手术进行干预,我们决定安排一次外科手术,并在第一次手术后8周进行了新的对照图像检查,结果显示气胸和胸腔积液完全自然消退,尽管大疱仍然存在。决定不需要进一步干预,患者出院。讨论:SARS-CoV2感染表现为不同类型的肺损伤,并可能有长期的肺部后遗症,这些后遗症只有在感染后的头几个月里通过明智和严格的随访才能发现。然而,英国胸科学会(British Thoracic Society, BTS)建议在出现初始症状3个月后进行第一次影像学随访,因为这段时间影像学改变的发生率很高,隐匿性恶性肿瘤的可能性较小。这个病例描述了一个罕见的肺损伤的表现,并发症同样自发的解决,证实了BTS提出的时间框架。

A 20-year-old asymptomatic Caucasian female has been screened to the clinic for COVID-19 testing due to the recent pandemic. She works in the primary care clinic where covid-19 patients are not seen. She has a past medical history of diabetes Mellitus and thyroid nodule. Her vitals are Temp 96.2 F, BP 123/89, RR 18, spo2 99% on air. On physical examination, her nasal turbinates were pale bilaterally, with no throat congestion. She denies any cough, congestion, fever, muscle aches, shortness of breath, sore throat, loss of taste, or smell sensation. On Investigation: Early march IgG antibody positive for covid-19 and in late May, she was tested positive for RT-PCR covid-19 without symptoms both times. On both occasions, she was working with healthcare workers without strict preventive protocols, who came negative for tests. Her family and close contacts tested negative for COVID-19. Diagnosis: Asymptomatic covid 19 carriers. Treatment: Close monitoring for symptoms. Discussion: Over the last year, the COVID-19 pandemic has caused significant concern worldwide due to its rapid spread. There are few notable symptomatic cases that are hospitalized and two months after discharge, they still tested positive on the RT-PCR COVID-19 test. It means they are a dormant carrier for COVID-19. But, in our case, the patient was asymptomatic and positive for COVID-19 antibody and RT-PCR test. Surprisingly, all healthcare workers in the clinic came negative on repeated testing. We presumed that she encountered some covid-19 strain, which remains dormant in the body and non-contagious. We need further studies to evaluate the COVID-19 dormant stage like hepatitis-B and tuberculosis.
由于最近的大流行,一名20岁的无症状白人女性被筛查到诊所进行COVID-19检测。她在初级保健诊所工作,那里看不到covid-19患者。既往有糖尿病和甲状腺结节病史。她的生命体征是体温96.2华氏度,血压123/89,心率18,血氧饱和度99%。体格检查,双侧鼻甲苍白,无咽喉充血。她否认有任何咳嗽、充血、发烧、肌肉疼痛、呼吸短促、喉咙痛、味觉丧失或嗅觉丧失。调查情况:3月初,她的covid-19 IgG抗体呈阳性,5月下旬,她的RT-PCR covid-19检测均呈阳性,两次均无症状。在这两种情况下,她都是在没有严格预防协议的情况下与医护人员一起工作,这些医护人员的检测结果均为阴性。她的家人和密切接触者COVID-19检测呈阴性。诊断:无症状感染者。治疗:密切监测症状。讨论:在过去一年中,COVID-19大流行因其迅速传播而引起了全世界的严重关切。有明显症状的住院病例极少,出院2个月后RT-PCR检测仍呈阳性。这意味着它们是COVID-19的休眠携带者。但是,在我们的病例中,患者无症状,COVID-19抗体和RT-PCR检测呈阳性。令人惊讶的是,诊所的所有医护人员在反复检测中都呈阴性。我们推测她遇到了某种covid-19病毒株,这种病毒在体内处于休眠状态,不会传染。我们需要进一步的研究来评估COVID-19的休眠阶段,如乙型肝炎和结核病。
