摘要: 12岁青少年女性,病程6年,肾脏损害表现为慢性肾炎综合征,期间确诊合并型甲基丙二酸血症(MMA),半年前停用药物治疗。本次入院肾穿刺活检提示血栓性微血管病(TMA),基因检测提示MMACHC基因复合杂合突变。补充钴胺素、叶酸、甜菜碱、左卡尼汀及福辛普利治疗,病情好转。MMA合并肾损伤病例少见,旨在提高临床医生对本病的认识。

Abstract: A 12-year-old adolescent female with chronic kidney disease for more than 6 years. During this period, she was diagnosed with methylmalonic acidemia with hyperhomocysteinemia. The patient discontinued drug therapy six months ago.Renal biopsy indicated thrombotic microangiopathy (TMA) and genetic testing revealed compound heterozygous mutations in the MMACHC gene. The patients condition improved after receiving treatment with cobalamin, folic acid, betaine, levocarnitine, and fosinopril. There are few cases of MMA with renal injury. The aim is to expanded clinicians understanding of this disease.

Key words: methylmalonic acidemia, thrombotic microangiopathy, hyperhomocysteinemia, MMACHC gene
