Glutaric aciduria type 2 is a rare inborn disease of fatty acid metabolism. The clinical manifestation of this disease is heterogeneous and ranges from severe neonatal forms to mild late-onset forms. We present a case of a previously healthy 22-year-old woman with unexplainable hypoglycemia and encephalopathic hyperammonemia. Acylcarnitine profile and organic acids analysis were compatible with glutaric aciduria type 2. On suspicion of this disease, the patient started supplements with carnitine and riboflavin, along with hemodialysis with a complete recovery. The genetic test confirmed the diagnosis. Glutaric aciduria type 2 has no cure and the metabolic decompensation can be a severe event, but treatable and preventable, if this pathology gets recognized.
戊二酸血症2型是一种罕见的脂肪酸代谢先天性疾病。该疾病的临床表现具有异质性,范围从严重的新生儿型到轻度的晚发型。我们报告一例病例,一名22岁既往健康的女性,出现无法解释的低血糖和脑病性高氨血症。酰基肉碱谱和有机酸分析与戊二酸血症2型相符。怀疑患有该疾病后,患者开始补充肉碱和核黄素,并进行血液透析,最终完全康复。基因检测确诊了该诊断。戊二酸血症2型无法治愈,代谢失代偿可能是严重事件,但如果能识别这种疾病,是可治疗和可预防的。
