Two patients are described with chronic hypoglycaemia; the first having glucose-6-phosphatase deficiency (type I glycogen storage disease), and the second fructose 1:6-diphosphatase deficiency. Both cases were associated with a bleeding diathesis, a defect of platelet aggregation, and a deficiency of platelet adenine nucleotides. The effect on the platelet abnormalities of a period of normoglycaemia was studied in both patients. Correction of the platelet abnormalities occurred rapidly after stabilization of the blood glucose within the normal range. Normal function persisted for the duration of the normoglycaemia, facilitating diagnostic liver biopsy and surgical procedures. A biochemical explanation for the nucleotide deficiency is suggested.
本文描述了两名患有慢性低血糖症的患者;第一名患者患有葡萄糖-6-磷酸酶缺乏症(I型糖原贮积病),第二名患者患有1:6-二磷酸果糖酶缺乏症。这两个病例均伴有出血倾向、血小板聚集缺陷和血小板腺嘌呤核苷酸缺乏。对两名患者正常血糖期对血小板异常的影响进行了研究。血糖稳定在正常范围内后,血小板异常迅速得到纠正。在正常血糖期内,正常功能持续存在,有利于进行诊断性肝活检和外科手术。本文还提出了核苷酸缺乏的生化解释。
