An 8-year-old boy with late onset multiple carboxylase deficiency is described. Biotinidase deficiency and holocarboxylase-synthetase deficiency have been excluded. A very slow biochemical response to biotin was found. The decrease in urinary organic acid excretion followed first-order kinetics with a half-life of about 50 days. The initially low carboxylase activities in thrombocytes were increased but not normalized after 3 months of treatment.
本文描述了一名患有迟发性多种羧化酶缺乏症的8岁男孩。已排除生物素酶缺乏症和全羧化酶合成酶缺乏症。发现该男孩对生物素的生化反应非常缓慢。尿有机酸排泄量的减少遵循一级动力学,半衰期约为50天。治疗3个月后,血小板中最初较低的羧化酶活性有所增加,但未恢复正常。
