Hepatitis C virus infection is a major public health problem with an estimated global prevalence of 3% and an estimated 5-20% of infected patients will develop liver cirrhosis .The Prevalence of Hepatitis C infection in end stage renal disease is greater than in the general population especially in those on hemodialysis which reflects nosocomial transmission of the disease in the hemodialysis environment.~Hepatitis C associated glomerulonephritis is an immune complex disease that occurs in 21% of patients who have HCV infection. It most commonly presents as membranoproliferative and mixed cryoglobulinemia It characterized by an indolent course in one third of patients , remission in another third and relapsing course in the remaining patients with potential progression to advanced chronic kidney disease.~mechanism of injury : Chronic Hepatitis C is primarily associated with type II cryoglobulinemia , in which the primary mechanism of injury is vasculitis that occurs via immune complex deposition.~hepatitis C virus related glomerular disease :~Type I membranoproliferative was the most common finding associated with mixed cryoglobulinemia but other forms of glomerulonephritis were associated with Hepatitis c like mesangial glomerulonephritis,focal and segmental glomerulonephritis,minimal change nephropathy,membranous nephropathy , Fibrillary glomerulonephritis,immunotactoid glomerulopathy,IgA nephropathy, vasculitic renal involvement ,poly arteritis nodosa and interstitial nephritis .
