          Abstract

          In recent years, significant advances have been made in understanding the pathogenesis and etiology of membranoproliferative glomerulonephritis (MPGN). A new classification system based on pathological immunofluorescence findings has been proposed to replace the traditional clinical classification system in order to better identify the underlying causes of MPGN and to provide guidance for more individualized treatment. We conducted a retrospective survey of the MPGN patients treated in our hospital from 2000 to 2012 and report here the validation of this new classification system in this cohort. A total of 34 patients were diagnosed with MPGN, including 25 males and 9 females. There were 3 cases of secondary MPGN, including 1 case due to monoclonal gammopathy of undetermined significance (MGUS) and 2 cases related to hepatitis B virus (HBV) infection. Clinical presentations included nephrotic syndrome (76.5%), microscopic hematuria (79.4%), hypocomplementemia (58.8%), renal insufficiency (82.4%), hypertension (100%), and peripheral edema (100%). All patients were treated with prednisone and immunosuppressive agents, mainly cyclophosphamide. During follow-up (median 6 months, range 3-47 months), 4 patients were lost to follow-up and 2 patients progressed to end-stage renal disease. In Western countries the main cause of secondary MPGN was hepatitis C virus or HBV infection, here however we report 2 cases related to HBV infection. MGUS-associated MPGN was less frequent in the Chinese cohort. Future studies should be designed to evaluate the association of the new classification system and clinical outcomes of MPGN.
