Abstract

Abstract:

C1q nephropathy is a glomerular disorder with prominent mesangial proliferation. It is characterized by mesangial dense deposits under electron microscopy and C1q deposits under immunofluorescence microscopy. The histologic pattern of C1q nephropathy can be divided into three kinds: minimal change disease (MCD), focal segmental glomerulosclerosis (FSGS), and immune-mediated proliferative glomerulonephritis. Its clinical presentation is heterogenous, ranging from nephritic to nephrotic proteinuria, with or without hematuria and renal insufficiency. Glucocorticoids remain the mainstay of treatment. Most studies indicated poor response of C1q nephropathy to glucocorticoids. The treatment of integrated Chinese and western medicine for C1q nephropathy is promising.
