ABSTRACT

Objective To explore the relationship between the pathological classification and clinical manifestations of lupus nephritis(LN)in children by renal biopsy and laboratory examination. Methods Renal biopsy and routine laboratory tests were performed in 35 cases of LN . The pathological classification of LN was made according to the criteria of WHO1982. Results Type Ⅳ of LN was most common(37.4%), and type Ⅴ(31.7%) and type Ⅲ(20.0%) were next. Type Ⅳ and type Ⅴ usually appeared as nephritic syndrome, while Type Ⅱ and Ⅲ mainly appeared as nephritis syndrome. The frequency of hypertension and renal dysfuction was the highest in type Ⅳ. Generally the renal interstitial injury of LN was mild, but that of type IV of LN was relatively obvious. There was a positive correlation between serum creatinine level and the degree of renal interstitial injury. Conclusion Lupus nephritis in childhood possessed some features in renal pathological change and clinical manifestations. Renal biopsy was important to diagnosis, treatment and prognosis evaluation of lupus nephritis.
