Abstract

Mixed cryoglobulinemia is often associated with hepatic C virus infection and is less common with hepatitis B virus infection, and it often progresses into lymphoproliferative diseases. Rituximab is known to achieve systemic B-cell depletion and clinical remission of the systemic effects of cryoglobulins in hepatitis C virus-associated cryoglobulinemia. Conversely, there are few reports regarding the use of rituximab in hepatitis B virus-associated cryoglobulinemia. We report here the case of a 65-year-old Japanese female who presented with lymphoproliferative disease-related cryoglobulinemia with hepatitis B virus, including membranoproliferative glomerulonephritis with renal failure. The vasculitis was refractory to conventional and antiviral therapy, but rituximab use led to control the disease. Our case highlights the benefit and efficacy of rituximab in association with antiviral therapy in small vessel vasculitis related to lymphoproliferative disease-related cryoglobulinemia with hepatitis B virus.
