摘要: 目的 探讨血浆置换(plasma exchange, PE)联合血液透析(hemodiafiltration, HDF)对儿童狼疮性肾炎(lupus nephritis, LN)的临床疗效。方法 我们搜集了2022年1月1日—2024年8月31日收治在本院风湿免疫科室并做血浆置换的12名LN患儿进行回顾性分析。根据患儿的病情、性别、身高、体重、红细胞压积等指标制定治疗方案。检测患儿PE前后抗核抗体(ANA)、抗dsDNA抗体、血红蛋白(Hb)、白细胞(WBC)、血小板(PLT)、总蛋白(TP)、白蛋白(ALB)、球蛋白(GLB)、白球比(A/G)和凝血功能水平;检测出院时肌酐和尿素氮水平及置换期间肌酐的变化趋势。结果 12名患儿平均血浆置换次数约为3次,平均每次置换液总量约为1 600(1 200~2 200)mL,大约为1.3±0.23倍总血浆容量(total plasma volume, TPV),PE前后Hb、PLT、PT、PTA、INR、ALB、Cr、BUN无统计学差异(P>0.05),ANA和抗dsDNA抗体、WBC、APTT、FIB、TP、GLB、A/G具有统计学意义(P<0.05)。出院时患儿肌酐均降至100 μmol/L左右,尿蛋白阳性强度也显著减弱。结论 PE联合HDF,可有效改善狼疮性肾炎患儿的肾功能水平。

Abstract: Objective To investigate the clinical efficacy of plasma exchange (PE) and hemodialysis (HD) in children with lupus nephritis. Methods We retrospectively analyzed 12 children with lupus nephritis who were admitted to the Department of Rheumatology and Immunology of our hospital for plasmapheresis from January 1, 2022 to August 31, 2024. The treatment is formulated according to the children's condition, gender, height, weight, hematocrit and other indicators. The levels of ANA, Anti-dsDNA antibody, hemoglobin, white blood cells, platelets, total protein, albumin, globulin, white globulin ratio and coagulation function were measured before and after PE. The changes in creatinine and urea nitrogen levels at discharge and during replacement were detected. Results The average number of plasma exchanges in 12 children was about 3, and the average total amount of replacement fluid was about 1 600 (1 200~2 200) mL, which was about 1.3±0.23 total plasma volume (TPV), and there were no statistically significant differences in Hb, PLT, PT, PTA, INR, ALB, Cr, and BUN before and after PE (P>0.05), WBC, APTT, FIB, TP, GLB, A/G ware statistically significant (P<0.05). At discharge, the creatinine of the children decreased to about 100 μmol/L, and the positive intensity of urine protein was also weakened. Conclusion PE combined with HDF can effectively improve renal function in children with lupus nephritis.
