Abstract
OBJECTIVES:Methotrexate (MTX)-induced hepatotoxicity is a significant clinical problem that may affect overall prognosis and disease outcome. Oxidative stress is a key player in its pathogenesis. The aim of this study was to investigate the role of ω-3 fatty acids as an adjuvant therapy in children and adolescents with acute lymphoblastic leukemia (ALL) during the maintenance phase of chemotherapy and the effect of ω-3 on MTX-induced hepatotoxicity. METHODS: This randomized, double-blind, placebo-controlled trial included 70 patients with ALL who were in the maintenance phase. The participants were divided into two groups: group A received oral MTX and ω-3 fatty acids (1000 mg/d) and group B (received MTX and placebo). Both groups were followed-up for 6 mo with assessment of liver enzymes, total antioxidant capacity (TAC), uric acid, malondialdhyde, superoxide dismutase (SOD), and glutathione peroxidase. The trial was registered at ClinicalTrials.gov (NCT02373579). RESULTS: Baseline clinical and laboratory parameters were consistent between the two groups (P > 0.05). After 6 mo, liver enzymes and malondialdhyde increased, whereas TAC, uric acid, SOD, and glutathione peroxidase decreased in group B (MTX and placebo) compared with baseline levels or with group A ALL patients receiving ω-3 fatty acids (P < 0.001). The addition of ω-3 to MTX maintained normal liver function and oxidant-antioxidant levels among group A patients at the end of treatment compared with pretherapy levels (P > 0.05). No adverse reactions due to ω-3 supplementation were reported. ALT was inversely correlated to TAC and SOD in the MTX group. CONCLUSIONS: The study determined that ω-3 fatty acids ameliorated MTX-induced hepatotoxicity and could be safely used during the maintenance phase of ALL.
