Abstract:
Objective To analyze the clinical characteristics,prognosis and the risk factors in 48 children with lupus nephritis combined with renal insufficiency.Methods The clinical data from 48 pediatric lupus nephritis with renal insufficiency from January 2000 to January 2013 were retrospectively analyzed.Results Forty-eight cases showed renal insufficiency among 168 children with lupus nephritis,and the incidence rate was 28.6％.The age ranged from 5.8 to 16.2 years.The male to female ratio was 1.0 ∶ 2.2.Among 48 children,43 cases had hematuria,41 cases had heavy proteinuria,25 cases had anaemia and 23 cases had persistent hypertension.Totally 20 cases underwent renal biopsy,and among them,15 cases(75.0％) were diagnosed as diffuse proliferative lupus nephritis(class Ⅳ).The histological activity index was ≥7 in 13 cases and the histological chronicity index was ≥4 in 3 cases.Corticosteroid and/or cytotoxic drugs were used in all of 48 cases.Thirty-five cases had normal urine and renal function,5 cases had stable renal function with persistent proteinuria,4 cases developed into chronic renal failure and 4 cases died.Persistent hypertension (x2 =4.274,P =0.039),the time of starting therapy (x2 =28.830,P =0.000),and histologic chronicity index(P =0.008 8 by Fisher's exact probability test)were the prognostic factors.Conclusions Among pediatric lupus nephritis with renal insufficiency,class Ⅳ (diffuse proliferative lupus nephritis) is the most frequent finding.Persistent hypertension,the time of starting therapy,and histologic chronicity index are the prognostic factors.The outcomes of lupus nephritis with insufficiency can be improved by adequate and appropriate treatment.
