Acute Renal Failure and Nephrotic Syndrome Secondary to Collapsing Glomerulopathy Associated With Hepatitis C.

Collapsing glomerulopathy (CG) is a rare variant of focal segmental glomerulosclerosis (FSGS) that commonly presents as nephrotic syndrome in patients. CG is almost always associated with human immunodeficiency virus (HIV) infection but is rarely from other infectious sources such as parvovirus, Epstein-Barr virus, cytomegalovirus, and SARS-CoV-2. CG has also been reported to be related to other etiologies such as genetic disorders, lupus, malignancy, and post-renal transplant but is exceedingly rare when related to hepatitis C virus (HCV). In this report, we describe the case of a patient presenting with nephrotic syndrome secondary to CG caused by newly diagnosed HCV.
