Abstract: Objective To explore the clinical and pathological features, treatment, and prognosis of capillary proliferative purpura nephritis (DEP-HSPN) in children. Methods The clinical data of 19 children diagnosed with DEP-HSPN were retrospectively analysis. Fifty-five children diagnosed with HSPN by renal biopsy were randomly selected as control group. Results The average age was 10.6±2.6 years old, and the average course of disease were 19.4±7.4 days before renal biopsy in 19 children with DEP-HSPN (14 males and 5 females) who make up 3.92% of anaphylactic purpura nephritis children confirmed by renal biopsy in the same period. In these 19 children, there were 10 cases having nephrotic syndrome and 9 case having hematuria and proteinuria type, all of whom were received immunosuppressive therapy. Finally, 14 cases achieved completely remission and 5 cases had partly remission. All of their classifications of renal pathology were Ⅲb levels, accompanied with 6.38% to 36.36% of crescents. Compared with 55 age and sex matched children with renal pathology classification of Ⅲb, the DEPHSPN children had shorter disease course, higher level of proteinuria, and lower pathological score of chronic renal injury (P all < 0.05). There was similar percentage of crescent between two groups. Conclusions Children with DEP-HSPN usually have rapid onset, severe clinical manifestations, more active lesions and less chronic lesions. There is no evidence that the capillary proliferative lesion is a risk factor in the prognosis of HSPN so far.
