Hepatitis C virus infection is associated with many extrahepatic manifestations such as mixed cryoglobulinemia (MC). Renal manifestation of HCV infection might present as cryo-positive membranoproliferative glomerulonephritis (MPGN). First-line therapy includes antiviral treatment as the underlying infection leads to formation of immune complexes. After introducing direct-acting antiviral agents (DAAs) cure rates of HCV infection increased. Sustained virologic response (SVR) is defined as the absence of HCV RNA in serum by a sensitive test performed 12 or 24 weeks after the end of antiviral treatment. Although HCV RNA is undetectable in the serum, it may be present in hepatocytes and peripheral blood mononuclear cells (occult HCV infection). However, the impact of DAA treatment on occult HCV infection is not clear. We report a case of recurrence of MC with MPGN and development of lymphoproliferative disorder 2 years after achieving SVR.
