Of the 136 patients, 102 patients were classified into the glomerular C3low group and 34 patients were classified into the glomerular C3high group. Patients in C3high group had more immune complexes deposition than those in C3lowgroup. In C3highgroup, the degree of renal lesion and interstitial fibrosis were severer compared to C3low group. Renal biopsy in C3high group presented with higher density of interstitial inflammatory cells that in C3low group. The density of glomerular C3 deposition was associated with poor renal survival over a 105-month follow-up.
