目的 研究治疗剂量的三氧化二砷(As2O3)对小儿急性早幼粒细胞白血病(APL)肾脏的毒性.方法 对37例小儿APL静脉滴注As2O3患者进行肾脏毒性监测:尿常规、尿微量蛋白[α1-微球蛋白(α1-MG)、微量清蛋白(mAlb)、β2-微球蛋白(β2-MG)、转铁蛋白(TRF)]定量、肾功能等检查.结果 治疗前白细胞尿5例(13.5%),治疗后第1周复查均转为正常;治疗前红细胞尿3例(8.1%);蛋白尿6例(16.2%);酮体(2+~3+)6例(16.2%),考虑与发热、进食少有关,1周后消失;血清尿素氮(BUN)、肌酐(Cr)、尿酸(UA)在诱导缓解期均未见异常性改变;与治疗前相比,尿α1-MG在第2周明显升高;β2-MG在第3周明显升高(P<0.01),但恢复较慢,第5周与α1-MG共同恢复正常.mAlb和TRF在诱导缓解期未见明显改变.结论 常规剂量As2O3治疗小儿APL肾脏毒性较轻,存在一过性肾小管的功能损害,诱导缓解期的第2~5周是重点监测时期.As2O3累积量的变化,对小儿肾脏功能的近期影响不大.尿微量蛋白联合检测比传统的血BUN、Cr更能反应肾小管的损害程度,动态检测其变化可以早期发现砷剂的肾脏损害.
目的 研究治療劑量的三氧化二砷(As2O3)對小兒急性早幼粒細胞白血病(APL)腎髒的毒性.方法 對37例小兒APL靜脈滴註As2O3患者進行腎髒毒性鑑測:尿常規、尿微量蛋白[α1-微毬蛋白(α1-MG)、微量清蛋白(mAlb)、β2-微毬蛋白(β2-MG)、轉鐵蛋白(TRF)]定量、腎功能等檢查.結果 治療前白細胞尿5例(13.5%),治療後第1週複查均轉為正常;治療前紅細胞尿3例(8.1%);蛋白尿6例(16.2%);酮體(2+~3+)6例(16.2%),攷慮與髮熱、進食少有關,1週後消失;血清尿素氮(BUN)、肌酐(Cr)、尿痠(UA)在誘導緩解期均未見異常性改變;與治療前相比,尿α1-MG在第2週明顯升高;β2-MG在第3週明顯升高(P<0.01),但恢複較慢,第5週與α1-MG共同恢複正常.mAlb和TRF在誘導緩解期未見明顯改變.結論 常規劑量As2O3治療小兒APL腎髒毒性較輕,存在一過性腎小管的功能損害,誘導緩解期的第2~5週是重點鑑測時期.As2O3纍積量的變化,對小兒腎髒功能的近期影響不大.尿微量蛋白聯閤檢測比傳統的血BUN、Cr更能反應腎小管的損害程度,動態檢測其變化可以早期髮現砷劑的腎髒損害.

Objective To study the renal toxicity of arsenic trioxide (As2O3) with therapeutic dose in acute promyelocytic leukemia (APL) in childhood. Methods Renal toxicity of 37 APL was monitored. The examinations of urinary routine, urinary microproteins[αt1-microglobulin (α1-MG), microalbumin (mAlb),β2-microglobulin (β2-MG), transferrin(TRF)] and renal function were performed. Results Five cases with leukocyturia, three cases with hematuria, six cases with proteinuria were observed before therapy. Ketonuria occurred in six cases associated with fever and less diet; overall abnormality disappeared in the first week. No significant changes of blood uric nitrigen(BUN), serum creatinine(Cr) and uric acid (UA) were founded in induction remission. Compared with tests before As2O3 infusion, obvious increase of uric α1-MG occurred in second week with arsenic trioxide, obvious increase of uric β2-MG in third week (P <0.01), slow recovery of uric α1-MG and β2-MG in fifth week. No significant changes of uric mAlb and TRF were seen in induction remission. Conclusion The renal toxicity of As2O3 was gentle in general therapeutic dose, renal tubercular damage could be seen. The important monitoring period were the second to fifth week in induction remission.Influence of As2O3 cumulant on renal function was not serious in the near future in childhood. The combined detection of urinary microproteins with dynamic variety could detect early renal damage with As2O3.
