ABSTRACT
BACKGROUND: Evidence has shown a close association between COVID-19 infection and renal complications in both individuals with previously normal renal function and those with chronic kidney disease (CKD). METHODS: The aim of this study is to evaluate the in-hospital mortality of SARS-CoV-2 patients according to their clinical history of CKD or estimated glomerular filtration rate (eGFR). This is a prospective multicenter observational cohort study which involved adult patients (≥18 years old) who tested positive with SARS-CoV-2 infection and completed their hospitalization in the period between November 2020 and June 2021. RESULTS: 1246 patients were included in the study, with a mean age of 64 years (SD 14.6) and a median duration of hospitalization of 15 days (IQR 9-22 days). Cox's multivariable regression model revealed that mortality risk was strongly associated with the stage of renal impairment and the Kaplan-Meier survival analysis showed a progressive and statistically significant difference (p < 0.0001) in mortality according to the stage of CKD. CONCLUSION: This study further validates the association between CKD stage at admission and mortality in patients hospitalized for COVID-19. The risk stratification based on eGFR allows clinicians to identify the subjects with the highest risk of intra-hospital mortality despite the duration of hospitalization.
ABSTRACT
Hemothorax (HT) and pulmonary hematoma represent rare complications of anticoagulant therapy. We present a rare case of a 53-year-old man with COVID-19 pneumonia who showed, in a follow-up computed tomography (CT) scan 13 days after hospitalization, a left HT and a small hyperdense area in a subpleural location and compatible with a small subpleural hematoma. This patient was being treated with a subcutaneous administration of low-molecular-weight heparin (100UI/kg/BID). No vascular malformations were visualized on the CT pulmonary angiography. Herein, we report the first case of both a spontaneous HT and a lung subpleural hematoma in a COVID-19 patient, probably caused by anticoagulant therapy.
