儿童狼疮性肾炎45例临床、病理及免疫学分析

摘要

目的：探讨儿童狼疮性肾炎（LN）的临床、病理及免疫学特点。方法回顾性分析住院治疗的45例LN患儿的临床和病理资料及免疫学指标。结果45例LN患儿中男6例、女39例，平均发病年龄（10.9±2.8）岁。临床表现为急性肾炎综合征型最常见，占42.2%，肾病综合征占31.1%。42例进行病理分型，其中Ⅱ型8例（17.8%），Ⅲ型2例（4.4%），Ⅳ型22例（48.9%），Ⅴ型1例（2.2%），Ⅴ＋Ⅲ型3例（6.7%），Ⅴ＋Ⅳ型6例（13.3%）。在治疗初期临床缓解率达91.1%，随访24个月15.0%复发。结论 LN患儿的临床表现具有多样性，肾脏病理复杂多变，部分患儿临床表现与肾脏病理表现不一致。%Objective To analyze the clinical and immunological features of 45 pediatric patients with lupus nephritis (LN). Methods Forty-five LN patients were included in this study. Clinical, pathological data and immunological parameters were retrospectively analyzed. Results Forty-five LN patients had 6 males and 39 females, with the mean onset age of (10.9 ± 2.8) years. Acute nephritis was the most common type, accounting for 42.2%. Nephrotic syndrome accounted for 31.1%. Renal biopsy showed class II (17.8%), III (4.4%), IV (48.9%), V (2.2%), V+III (6.7%)and V+IV (13.3%)in 42 cases. The remis-sion rate reached 91.1%in the early therapeutic stage, and 15.0%patients recurred after 24-month follow-up. Conclusions The clinical manifestations of LN children are diverse. The renal pathology is complex. The clinical manifestations in part of the chil-dren are not consistent with renal pathology.
