Barbarroja K1 Humans K1 Methotrexate K1 Non-alcoholic Fatty Liver Disease K1 Autoimmunity AB Background: Liver alterations, especially nonalcoholic fatty liver disease(NAFLD) are associated with Rheumatoid Arthritis (RA). This abnormalityappears as asymptomatic and can progress to a severe liver damage rapidly.Chronic inflammation, treatment with methotrexate (MTX) or even autoimmunity are factors that might be involved, however the mechanisms related to this comorbidity in RA are not completely stablished yet.Objectives: 1) To evaluate the liver disease risk in RA patients through feasible indexes to be used in the daily clinical practice and its relationship with clinical features of the disease; 2) To analyze the impact of antibodies to citrullinated proteins antigens (ACPAs) on hepatic function; 3) To examine the influence ofMTX treatment on classical parameters and new indexes of hepatic dysfunction in a cross-sectional and longitudinal cohort.
