IgA Vasculitis With Nephritis (Henoch−Schönlein Purpura) in a COVID-19 Patient

In December 2019, a series of pneumonia cases of unknown etiology, which were epidemiologically linked to a seafood market, was reported in Wuhan, Hubei province, China. The disease has rapidly spread around the world, becoming a global pandemic. A coronavirus, which was named 2019 novel coronavirus (2019-nCov), was isolated from respiratory tract samples1 and later identified as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The name of the disease was officially changed to coronavirus disease 2019 (COVID-19). Pulmonary involvement with alveolar damage and acute respiratory failure has been the most remarkable clinical condition of COVID-19 patients. However, there is increasing evidence that this virus also affects other organs, kidney injury being relatively common in this infection and associated with an increased mortality rate.2 In a large prospective cohort of 701 COVID-19 patients in China, 44% had proteinuria and 27% had hematuria on admission. During hospitalization, 5.1% of them developed acute kidney injury.2 We report a patient who developed systemic symptoms and renal involvement after being hospitalized because of a COVID-19 infection. A mesangial proliferation and IgA deposits in the glomeruli were seen on the kidney biopsy specimen.
