Shortly thereafter, the patient experienced acute deterioration in respiratory status. aDay 1 in this table is the day of the first positive severe acute respiratory syndrome coronavirus 2 test. Autopsy findings in eight patients with fatal H1N1 influenza. Right hemothorax (day 29) required chest tube placement followed by video-assisted thoracoscopic surgery on day 31 with hemothorax evacuation. January Case of the Month Clinical History: A 1.8-cm solitary peripheral pulmonary nodule was resected in a 72-year-old woman with long-standing rheumatoid arthritis.The clinical suspicion was carcinoma or a rheumatoid nodule. There was no evidence of acute lung injury or capillaritis/vasculitis. Research has contributed to important advances in the pathological diagnosis of these respiratory disorders. Reverse transcriptase (RT)–PCR for SARS-CoV-2 by nasopharyngeal swab was positive (day 1). Chest x-ray at admission revealed low lung volumes with diffuse mixed bilateral interstitial and airspace opacities, a small right pneumothorax, and bilateral pleural effusions. DAD lies on the severe end of the ALI spectrum and is the histopathologic pattern typically associated with clinical ARDS. Lung pathology of fatal severe acute respiratory syndrome. Using mouse models of iron overload, the authors showed that increased iron levels resulted in reduced lung function and worse pulmonary fibrosis upon lung injury by bleomycin.

Hence, evaluating the influence of different vehicles on the lung due to intratracheal instillation is crucial. Chest radiograph on day 122 demonstrated low lung volumes with complete opacification of both hemithoraces. Chest computed tomography (CT) on day 35 Image 1A showed extensive airspace consolidation in the right lung, mixed airspace and ground-glass opacities in the left lung, and a loculated right hemopneumothorax. Another important limitation is that detailed clinical characteristics were not reported in all case series, including but not limited to comorbid conditions, duration of illness, timing of biopsy, and mechanical ventilation strategies, all of which could influence lung pathology. We describe the pathology in three patients with severe COVID-19 who underwent antemortem examination of lung tissue at least 8 weeks after initial diagnosis. Systematic Review of Lung Histopathology Features in COVID-19 Studies. A, Chest computed tomography coronal reformatted image (day 75) shows homogeneous diffuse bilateral consolidation with volume loss, traction bronchiectasis, and a few peripheral cystic changes likely representing early honeycombing (arrows).

Of the published autopsy cases of patients with COVID-19, the acute phase of DAD was the predominant pulmonary pathology, reported in 88% of cases (n = 151; Amongst the COVID-19 cases, six patients (4%) in one paper were described as having AFOP without hyaline membranes on needle biopsy. At this time, she developed septic shock attributed to a urinary tract infection (Proteus spp). Aspiration Risk Factors, Microbiology, and Empiric Antibiotics for Patients Hospitalized With Community-Acquired Pneumonia, Use of Ivermectin Is Associated With Lower Mortality in Hospitalized Patients With Coronavirus Disease 2019. This report offers an early glimpse into the longer-term pathologic aftermath of severe COVID-19 managed with prolonged mechanical ventilation and ECMO, summarized in Table 1. Also described findings consistent with aspiration pneumonia in a patient with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nasopharyngeal swab but with no evidence of SARS-CoV-2 pulmonary infection.

Using PRISMA-Individual Participant Data guidelines, our systematic review analysis included 26 articles representing 171 COVID-19 patients; 20 articles representing 287 H1N1 patients; and eight articles representing 64 SARS patients. Pulmonary post-mortem findings in a series of COVID-19 cases from northern Italy: a two-centre descriptive study. Using our search strategy, we identified 1,791 potentially relevant COVID-19 studies. Pulmonary microthrombi were reported in 57% of COVID-19 and 58% of SARS patients, as compared with 24% of H1N1 influenza patients. Certain severe viral pneumonias, such as cytomegalovirus, are known to cause a necrotizing bronchiolitis that conceptually could result in some pulmonary hemorrhage without evidence of vascular inflammation. Acute fibrinous and organizing pneumonia associated with influenza A/H1N1 pneumonia after lung transplantation. The presence of key histologic features were identified and summarized in all studies, including DAD, AFOP, organizing fibrosis, end-stage fibrosis, superimposed neutrophilic pneumonia, microthrombi, and pulmonary thrombi. Audio/Video Three-dimensional visualization of Epstein-Barr virus (EBV)-B95.8/firefly luciferase 2 (fLuc2) spread of infection and/or infected cells in long-term humanized mice.

A single small vessel demonstrated some intimal fibroplasia, but no definitive evidence of a thromboembolic event was seen. D, Filling of the airspaces by pigmented and foamy macrophages (H&E, ×40). Our current understanding of COVID-19 pathology is based almost entirely on autopsies (both complete and partial) and postmortem biopsies performed on patients dying after a few days to a few weeks of severe disease.1-25 In one series, the interval between onset of illness and death ranged from 1 to 32 days.25 In another, the range was 1 to 58 days (median, 21 days).23 A series of 30 “minimally invasive autopsies” included six patients with duration of illness listed as 63, 68, 75, 63, 71, and 82 days.6 Not unexpectedly, the most striking degree of tissue damage has consistently been reported in the lungs. Relevant topics include… More. We identified studies of 2003 SARS lung histopathology through a PubMed search for “SARS AND (Pathology OR Autopsy OR Biopsy).” Inclusion criteria for the SARS systematic review included: (1) fulfillment of the World Health Organization clinical criteria for SARS, including radiologic evidence of infiltrates consistent with pneumonia, fever > 38°C, and a history of chills, cough, malaise, or known exposure; (2) clinical suspicion of SARS-CoV infection as the primary cause of death; and (3) sufficient histologic description of each reported case. Two and a half months following lung transplantation (day 202, approximately 7 months after his initial diagnosis), he remains hospitalized, requiring mechanical ventilation in the intensive care unit. Following multiple negative RT-PCR tests for SARS-CoV-2, he was transferred to our institution for consideration of lung transplantation (day 74). The goals of care were switched to comfort, and she died on day 74. On day 18, a second dose of convalescent plasma was administered and cytokine filter treatment performed. Journal of Molecular Pathology (ISSN 2673-5261) is an international, multidisciplinary, peer-reviewed and scientific open access, open-source journal that covers every topic related to modern histopathology and cytopathology, predictive pathology and molecular cytopathology. Shortly thereafter, the patient experienced acute deterioration in respiratory status. aDay 1 in this table is the day of the first positive severe acute respiratory syndrome coronavirus 2 test. Autopsy findings in eight patients with fatal H1N1 influenza. Right hemothorax (day 29) required chest tube placement followed by video-assisted thoracoscopic surgery on day 31 with hemothorax evacuation. January Case of the Month Clinical History: A 1.8-cm solitary peripheral pulmonary nodule was resected in a 72-year-old woman with long-standing rheumatoid arthritis.The clinical suspicion was carcinoma or a rheumatoid nodule. There was no evidence of acute lung injury or capillaritis/vasculitis. Research has contributed to important advances in the pathological diagnosis of these respiratory disorders. Reverse transcriptase (RT)–PCR for SARS-CoV-2 by nasopharyngeal swab was positive (day 1). Chest x-ray at admission revealed low lung volumes with diffuse mixed bilateral interstitial and airspace opacities, a small right pneumothorax, and bilateral pleural effusions. DAD lies on the severe end of the ALI spectrum and is the histopathologic pattern typically associated with clinical ARDS. Lung pathology of fatal severe acute respiratory syndrome. Using mouse models of iron overload, the authors showed that increased iron levels resulted in reduced lung function and worse pulmonary fibrosis upon lung injury by bleomycin.
