Propionic acidemia (PA) is a rare, multi-systemic inborn error of metabolism. PA results from an impaired activity of the mitochondrial enzyme, propionyl-CoA carboxylase (PCC). PCC holds an essential role in the catabolic pathways for odd-chain fatty acids, cholesterol side-chains and branched-chain amino acids. Errors in these pathways result in the accumulation of toxic metabolites that may advance into end-organ damage and dysfunction. Clinical manifestations of PA include relapsing courses of severe metabolic acidosis, concurrent viral or bacterial infection, episodic vomiting, gastroesophageal reflux disease (GERD), seizures, developmental delay, hypotonia, hyperammonemia, osteopenia, pancreatitis and cardiomyopathy. This case describes a 3-year-old boy with PA who presented with an acute metabolic crisis, precipitated by () bacteremia and severe acute respiratory syndrome due to coronavirus 2 (SARS-CoV-2) co-infection. He required anesthetic management for surgical removal of an infected central venous port. Anesthetic care for this patient presented the unique challenges of metabolic decompensation amidst infection with SARS-CoV-2. Options for anesthetic care for patients with PA have been elucidated in the literature. However, to our knowledge, this is the first case to describe anesthetic management in a PA patient with SARS-CoV-2.
丙酸血症(PA)是一种罕见的、多系统的先天性代谢紊乱疾病。PA是由线粒体酶丙酰辅酶A羧化酶(PCC)活性受损所致。PCC在奇数链脂肪酸、胆固醇侧链和支链氨基酸的分解代谢途径中起重要作用。这些途径中的错误会导致有毒代谢产物的积累,进而可能发展为终末器官损伤和功能障碍。PA的临床表现包括严重代谢性酸中毒的复发过程、并发病毒或细菌感染、发作性呕吐、胃食管反流病(GERD)、癫痫发作、发育迟缓、肌张力减退、高氨血症、骨质减少、胰腺炎和心肌病。本病例描述了一名3岁PA男孩,因()菌血症和新型冠状病毒2(SARS-CoV-2)共同感染导致的严重急性呼吸综合征而引发急性代谢危机。他需要进行麻醉管理以手术取出感染的中心静脉导管。该患者的麻醉护理面临着SARS-CoV-2感染期间代谢失代偿的独特挑战。文献中已阐明了PA患者的麻醉护理选择。然而,据我们所知,这是第一例描述SARS-CoV-2感染的PA患者麻醉管理的病例。
