Cannabis consumption and non-alcoholic fatty liver disease. A three years longitudinal study in first episode non-affective psychosis patients. Prog Neuropsychopharmacol Biol Psychiatry. 2019 Dec 20;95:109677http://hdl.handle.net/10668/14157Increased incidence of obesity and excess weight lead to an increased incidence of non-alcoholic fatty liver disease (NAFLD). Recent evidence indicates a protective effect of cannabis consumption on weight gain and related metabolic alterations in psychosis patients. Overall, patients are at greater risk of presenting fatty diseases, such as NAFLD, partly due to lipid and glycemic metabolic disturbances. However, there are no previous studies on the likely effect of cannabis on liver steatosis. We aimed to explore if cannabis consumption had an effect on hepatic steatosis, in a sample of first-episode (FEP) non-affective psychosis. A total of 390 patients were evaluated at baseline and after 3 years of initiating the antipsychotic treatment. Anthropometric measurements and liver, lipid, and glycemic parameters were obtained at both time points. All but 6.7% of patients were drug-naïve at entry, and they self-reported their cannabis use at both time points. Liver steatosis and fibrosis were evaluated through validated clinical scores (Fatty Liver Index [FLI], Fibrosis-4 [FIB-4], and NAFLD). At 3-year follow-up, cannabis users presented significantly lower FLI scores than non-users (F = 13.874; p  Cannabis consumption may produce a protective effect against liver steatosis in psychosis, probably through the modulation of antipsychotic-induced weight gain.enAntipsychotic treatmentCannabisFirst-episode psychosisLiver fibrosisLiver steatosisMedication naïveTolerabilityTreatment outcomeAdultAntipsychotic AgentsBody Mass IndexFemaleHumansLongitudinal StudiesMaleMarijuana UseNon-alcoholic Fatty Liver DiseasePsychotic DisordersTriglyceridesWaist Circumferenceresearch article31228640open accessAntipsicóticosCircunferencia de la cinturaEnfermedad del hígado graso no alcohólicoEstudios longitudinalesTrastornos psicóticosTriglicéridosUso de la marihuana10.1016/j.pnpbp.2019.1096771878-4216https://repositorio.unican.es/xmlui/bitstream/10902/16453/3/CannabisConsumption.pdf
