摘要

肝毒性是用6-巯基嘌呤和甲氨蝶呤维持治疗急性淋巴细胞白血病(ALL)的常见并发症。甲基化6-巯基嘌呤代谢产物(MeMP)水平升高与肝毒性有关。然而,并非所有导致all患者肝功能衰竭的机制都是已知的。POLG基因编码线粒体DNA聚合酶γ(POLG1)的催化亚基,其变体与药物诱导的肝毒性有关,例如丙戊酸钠。研究了34例儿童ALL患者在维持治疗期间常见POLG变异与肝毒性的关系。在筛选的POLG变体中,在12名患者中检测到4种不同的变体。一名患者在MeMP水平未升高的情况下出现严重肝毒性,并携带杂合子POLG p.G517V变体,而在其他患者中未发现该变体。

DNA polymerase gamma variants and hepatotoxicity during maintenance therapy of childhood acute lymphoblastic leukemia: is there a causal relationship?
Hepatotoxicity is a frequent complication during maintenance therapy of acute lymphoblastic leukemia (ALL) with 6-mercaptopurine and methotrexate. Elevated levels of methylated 6-mercaptopurine metabolites (MeMP) are associated with hepatotoxicity. However, not all mechanisms are known that lead to liver failure in patients with ALL. Variants in the POLG gene, which encodes the catalytic subunit of mitochondrial DNA polymerase gamma (POLG1), have been related to drug-induced hepatotoxicity, for example, by sodium valproate. The association of common POLG variants with hepatotoxicity during maintenance therapy was studied in 34 patients with childhood ALL. Of the screened POLG variants, four different variants were detected in 12 patients. One patient developed severe hepatotoxicity without elevated MeMP levels and harbored a heterozygous POLG p.G517V variant, which was not found in the other patients.
