ABSTRACT

Objective: To examine outcomes in organ transplant and nontransplant patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during the initial 22 months of the pandemic. Patients and Methods: We used Optum electronic health records to compare outcomes between an adult transplant group and a propensity-matched nontransplant group that tested positive for SARS-CoV-2 from February 1, 2020, to December 15, 2021. Baseline characteristics, hospitalization, intensive care unit admission, mechanical ventilation, renal replacement therapy, inpatient, and 90-day mortality were compared between the transplant and nontransplant groups and among specific transplant recipients. Cox proportional analysis was used to examine hospitalization and mortality by organ transplant, medical therapy, sex, and the period of the pandemic. Results: We identified 876,959 patients with SARS-CoV-2 infection, of whom 3548 were organ transplant recipients. The transplant recipients had a higher risk of hospitalization (30.6% vs 25%, respectively; P<.001), greater use of mechanical ventilation (7.8% vs 5.6%, respectively; P<.001), and increased inpatient mortality (6.7% vs 4.7%, respectively; P<.001) compared with the nontransplant patients. The initiation of mechanical ventilation was significantly more frequent in the transplant group. After adjustment for baseline characteristics and comorbidities, the transplant group had a higher risk of hospitalization (odds ratio, 1.38; 95% confidence interval, 1.19-1.59), without a difference in mortality. In the transplant group, lung transplant recipients had the highest inpatient mortality (11.6%). Conclusion: Among patients with SARS-CoV-2 infection, the transplant recipients were at a higher risk of hospitalization and inpatient mortality; however, mortality was mainly driven by advanced age and comorbidities rather than by transplant status or immunosuppressive medications. Lung transplant recipients had the greatest inpatient and 90-day mortality.

ABSTRACT

CASE PRESENTATION: A 47-year-old man with poorly controlled diabetes mellitus (glycosylated hemoglobin 12%) presented to the ED with a 1-week history of fevers, productive cough, and dyspnea. The patient was febrile and hypoxemic on presentation; laboratory testing was remarkable for hyperglycemia and ketoacidosis. The initial chest CT scan showed right lower lobe consolidation and ground-glass opacities (Fig 1A). He was admitted to the ICU and administered IV antibiotics (cefepime and vancomycin) for the treatment of community-acquired bacterial pneumonia.

ABSTRACT

Controversy exists whether the cause of death due to severe acute respiratory syndrome coronavirus 2 is directly related to the infection or to underlying conditions. The purpose of this study is to assess the relationship of severe acute respiratory syndrome coronavirus 2 infection with the cause of death in hospitalized patients. DESIGN: Retrospective observational study; deidentified discharge summaries of deceased patients were reviewed by two intensivists and classified as coronavirus disease 2019-related (caused by severe acute respiratory syndrome coronavirus 2) or coronavirus disease 2019-unrelated (not caused by severe acute respiratory syndrome coronavirus 2 or indeterminate) deaths. For classification disagreement, a separate group of three intensivists reviewed the discharge summaries and arbitrated to determine the cause of death. SETTING: Single-center study performed at the University of Texas Medical Branch. PATIENTS: All adult patients (> 18 yr) admitted from March 10, 2020, to October 22, 2020, with positive severe acute respiratory syndrome coronavirus 2 test results who expired during their hospitalization were identified. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patient demographics, comorbidities, prescribed medications, and ventilatory support data were collected. Comparison between groups was performed using t test and chi-square test. During the study period, 1,052 patients were admitted within 14 days of severe acute respiratory syndrome coronavirus 2-positive test results, of whom 100 expired during the hospitalization. Deceased patients were predominantly male and older than 65 years. Obesity (body mass index ≥ 30 kg/m2) was present in 41%, and common comorbidities included hypertension (47%), diabetes (30%), and heart failure (20%). Death was classified as directly caused by severe acute respiratory syndrome coronavirus 2 in 85% and not caused by severe acute respiratory syndrome coronavirus 2 in 5%. An indeterminate cause of death in 10% was due to insufficient information or an atypical presentation. The observed interrater agreement on the cause of death classification was 81%. CONCLUSIONS: In this single-center study, the majority of deaths in severe acute respiratory syndrome coronavirus 2-positive hospitalized patients were related to a typical or atypical presentation of coronavirus disease 2019 disease.

ABSTRACT

Endoscopic lung volume reduction is now included in the guidelines for treatment in severe chronic obstructive pulmonary disease. Since December 2018, 2 valve systems have been approved by the US Food and Drug Administration (FDA). To date, there is no head-to-head trial comparing both valve systems and no clear benefit of one over the other. This article provides an overview of the two largest prospective trials performed with the FDA-approved valve systems.

ABSTRACT

Chronic histoplasmosis is typically diagnosed in patients who are immunocompromised or severely debilitated and who either live in or who have travelled to endemic areas. We report the case of a young, otherwise immunocompetent male patient who presented to a New York hospital with lobar consolidation and was found to have chronic pulmonary histoplasmosis. He described no history of travel to an endemic area. Immunological workup later revealed selective immunoglobulin M (IgM) deficiency. The literature has suggested a link between IgM deficiency and fungal infections. Recent research has also proposed a link between autoimmunity and IgM deficiency. Our clinical vignette describes the case of a patient with selective IgM deficiency who was diagnosed with pulmonary histoplasmosis without any clinical evidence of autoimmune disease.

ABSTRACT

OBJECTIVE: To describe a case of emphysematous hepatitis which is a rare clinical entity, characterized by a fatal, rapidly progressive infection of the liver with a radiological appearance simulating emphysematous pyelonephritis and to help provide more data about the causative organisms and precipitating factors of this pathology. DATA SOURCES AND SYNTHESIS: Relevant literature was reviewed and, to the best of our knowledge, there is limited data regarding the pathogenesis, causative organisms, and management of this condition. CONCLUSION: Emphysematous hepatitis is a rapidly progressive infection that can be fatal in the absence of appropriate therapeutic intervention. Initial clinical manifestations are usually subtle and thus high clinical suspicion is required for early diagnosis and management of this condition to help decrease the mortality rates.
