title: Effect of hyperthyroidism and propylthiouracil treatment on liver biochemical tests.
abstract: Liver biochemical test (LBT) changes can be commonly observed in hyperthyroid patients. Those kinds of changes could also be observed because of propylthiouracil (PTU) therapy. We prospectively evaluated LBT changes because of PTU use for 1 year in patients who had been diagnosed with hyperthyroidism first. We studied 64 patients who had been diagnosed with hyperthyroidism. These patients took at least 1-year PTU treatment. We analysed LBT at diagnosis and after 2 and 12 months of treatment with PTU. Prior to PTU treatment, 30 (46.8%) of the 64 patients had at least one LBT abnormality. We observed at least one LBT abnormality in 11 (32%) patients after 2 months and nine (26%) patients after 12 months of treatment with PTU in 34 patients whose CBT were normal before treatment. We did not observe any deterioration in clinical picture and bilirubin levels. Elevated serum LBT during the pretreatment and PTU treatment period is common and usually transient and asymptomatic. PTU could be used for long times by lowering the dose and close follow-up in patients who have elevated LBT during the pretreatment and after PTU treatment period.
