朱砂莲中毒致急性肾功能衰竭二例

Ciliatenerve Knotweed Root-induced Acute Renal Failure:A Report of Two Case

目的分析朱砂莲中毒导致急性肾功能衰竭临床表现、肾脏病理学及相关文献复习。方法 2007年3月-9月收治朱砂莲中毒急性肾功能衰竭2例,分析临床表现及肾脏病理损害。结果朱砂莲急性中毒易致急性肾功能衰竭,危及生命;其主要损害肾小管间质,表现为急性肾小管重度损伤,无炎性细胞浸润,而肾小球几乎无病变。结论朱砂莲为我国常使用中药,主要成分为马兜铃酸,易致马兜铃酸肾病,须提高对该病认识,规范使用中草药,避免药物性所致肾损害。

Objective To analyze the clinical and pathological manifestations of kidney in patients with ciliatenerve knotweed root-induced acute renal failure.Methods Two patients who were admitted into our hospital for acute renal failure caused by over-dose ciliatenerve knotweed root from March to September in 2007 were included in this study.We analyzed the clinical and pathological manifestations of their kidneys.Results Over-dose ciliatenerve knotweed root could induce acute renal failure,even threaten life.The pathology of kidney is characterized by severe tubular injury, rather than glomerulus damage,without cell infiltration.Conclusions Ciliatenerve knotweed root is one of the frequently-used traditional Chinese medicines in our country,which can easily result in aristolochinc acid nephropathy.We should recognize the importance of this disease and avoid using nephrotoxic drugs.
