Successful Treatment of COVID-19-Related ImmuneComplex Glomerulonephritis, Case Report

Acute kidney injury (AKI) , proteinuria in the nephrotic or subnephrotic range and hematuria might be seen in patients with coronavirus disease 2019 (COVID-19) infection. In this case study we present a 59 years old manwho was diagnosed with immune-complex glomerulonephritis after development of rapidly progressive kidney failure accompanied by pulmonary hemorrhage, 2 months after COVID-19 infection. The patient was hospitalised with the diagnosis of acute kidney injury and nephrotic syndrome. Hemodialysis was performed due to uremic symptoms. Cyclophosphamide, methylprednisolone and plasmapheresis were started. Pathologic examination of kidney biopsy revealed features compatible with immune complex-related acute glomerulonephritis. Cyclophosphamide and plasmapheresis were discontinued , and treatment with 1 mg/kg/day methylprednisolone was continued. Immune-complex glomerulonephritis can be seen following COVID-19 infection. İt is important to diagnose this disease entity as soon as possible . Steroidtherapy and other supportive modalities might be sufficient in the treatment.
