Clinical and laboratory prognostic factors associated with methanol toxicity outcomes in patients at Tabriz Sina Hospital: A retrospective study.

IntroductionMethanol toxicity is a significant health concern with potentially severe outcomes. This study aimed to investigate the prognostic factors of patients with methanol toxicity referred to Tabriz Sina Hospital.MethodsA descriptive-analytical retrospective study was conducted in methanol toxicity patients admitted in Tabriz Sina Hospital since 2019 to 2021. Demographic characteristics and management methods were extracted from the patients' medical records.ResultsPatients were predominantly male (91.3%) with a median age of 30-40 years. Winter accounted for 48.7% of cases. Coma (OR = 8.0, 95% CI: 3.2-19.9) and arrhythmia (OR = 5.5, 2.0-15.1) at admission, pH <7.1 (OR = 4.2, 2.0-8.9), elevated creatinine (OR = 1.3/mg/dL, 1.1-1.6), opiate co-use (OR = 2.8, 1.2-6.5), and delayed ethanol therapy (>3 h, OR = 2.3, 1.1-4.8) independently increased mortality risk. Bicarbonate, Eprex, and methylprednisolone reduced complications. Time from ingestion to admission (48-72 h) did not affect mortality, but delayed hemodialysis initiation worsened outcomes.ConclusionEarly presentation and providing early therapeutic modalities have a significant impact on the mortality rate and the patients' outcome.
