Pyroglutamic acidosis (PGA) is an underrecognized entity characterised by raised anion gap metabolic acidosis (RAGMA) and urinary hyper-excretion of pyroglutamic acid. It is frequently associated with chronic acetaminophen (APAP) ingestion. We report the case of a 73-year-old man with invasive pulmonary aspergillosis treated with voriconazole and APAP for analgesia with a cumulative dose of 160 g over 40 days. PGA was suspected as he developed severe RAGMA and common causes were excluded. Diagnosis was confirmed via urinary organic acid analysis which showed significant hyper-excretion of pyroglutamic acid. APAP was discontinued, and N-acetylcysteine (NAC) was administered. His RAGMA rapidly resolved following treatment.
焦谷氨酸酸中毒(PGA)是一种未被充分认识的病症,其特征为阴离子间隙代谢性酸中毒(RAGMA)升高和尿中焦谷氨酸排泄过多。它常与长期服用对乙酰氨基酚(APAP)有关。我们报告一例73岁男性侵袭性肺曲霉病患者,接受伏立康唑和APAP镇痛治疗,40天内累积剂量达160克。由于患者出现严重的RAGMA且排除了常见病因,故怀疑为PGA。通过尿有机酸分析确诊,结果显示焦谷氨酸排泄显著过多。停用APAP,并给予N-乙酰半胱氨酸(NAC)治疗。治疗后其RAGMA迅速缓解。
