Alterations of liver function test in patients treated with antipsychotics.
The prevalence of alterations of liver function tests in patients treated with a wide range of antypsychotics is unknown. The aim of this study was to analyze the effects of antipsychotics on liver function tests in a population of schizophrenic outpatients. Concentrations of AST, ALT, GGT, alkaline phosphatase, albumin, and bilirubin were determined in 54 patients fitting DSM-IV criteria of schizophrenia, and the same number of sex- and age-matched healthy subjects. Assessments included the Clinical Global Impression (CGI) and the Positive and Negative Syndrome Scale (PANSS) in addition to treatment related variables. Transaminases concentrations were slightly elevated in study patients compared to healthy controls, but without statistical significance. Alkaline phosphatase showed higher values in schizophrenic patients. Albumin and bilirubin were lower in study patients. Liver function tests abnormalities were found in about 10% of schizophrenic patients treated with antipsychotics. Treatment with depot phenotiazines induces alteration in these tests more frequently than treatment with other antipsychotics. PANSS negative subscale scores directly correlated with alkaline phosphatase and inversely correlated with albumin. A substantial number of patients in treatment with antipsychotic drugs present alterations of liver function tests. Both pharmacological and clinical factors could be related with these alterations.
