Thrombotic microangiopathy associated with cryoglobulinemic membranoproliferative glomerulonephritis and hepatitis C

Am J Kidney Dis. 1998 Mar;31(3):521-6. doi: 10.1053/ajkd.1998.v31.pm9506691.

Abstract

Cryoglobulinemic membranoproliferative glomerulonephritis (MPGN) and increased incidence of vascular thromboses are complications of hepatitis C virus (HCV) infection. This report describes the clinical, laboratory, and renal biopsy findings in two HCV-positive patients with cryoglobulinemic MPGN and thrombotic microangiopathy (TMA). Testing for circulating antiphospholipid antibodies, which are detected in a significant proportion of patients with HCV, was negative in the one case in which it was done. This article discusses the possible cause of the TMA in these two cases.
