A 54-year-old man with cryoglobulinemia and chronic hepatitis C infection presented with progressive renal insufficiency caused by membranoproliferative glomerulonephritis. Because of a steady decline in renal function, cyclophosphamide therapy was instituted. Within 1 month of starting therapy, his cryoglobulins disappeared, and in 3 months, his creatinine clearance had improved from 56 mL/min to 89 mL/min. At no point in his course was there clinical evidence of liver disease. After 1 year, cyclophosphamide was successfully stopped. Fourteen months later, his creatinine clearance is 105 mL/min. These results suggest that cyclophosphamide may be useful therapy for patients with cryoglobulinemic membranoproliferative glomerulonephritis and hepatitis C virus infection who have progressive renal insufficiency.

UI	MeSH Term	Description	Entries
D007676	Kidney Failure, Chronic	The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D003449	Cryoglobulinemia	A condition characterized by the presence of abnormal quantities of CRYOGLOBULINS in the blood. Upon cold exposure, these abnormal proteins precipitate into the microvasculature leading to restricted blood flow in the exposed areas.	Cryoglobulinemias
D003520	Cyclophosphamide	Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.

D006526	Hepatitis C	INFLAMMATION of the LIVER in humans caused by HEPATITIS C VIRUS, a single-stranded RNA virus. Its incubation period is 30-90 days. Hepatitis C is transmitted primarily by contaminated blood parenterally and is often associated with transfusion and intravenous drug abuse. However, in a significant number of cases, the source of hepatitis C infection is unknown.

D015432	Glomerulonephritis, Membranoproliferative	Chronic glomerulonephritis characterized histologically by proliferation of MESANGIAL CELLS, increase in the MESANGIAL EXTRACELLULAR MATRIX, and a thickening of the glomerular capillary walls. This may appear as a primary disorder or secondary to other diseases including infections and autoimmune disease SYSTEMIC LUPUS ERYTHEMATOSUS. Various subtypes are classified by their abnormal ultrastructures and immune deposits. Hypocomplementemia is a characteristic feature of all types of MPGN.
