POS1385 AUTOIMMUNE DISEASES ASSOCIATED WITH CHRONIC LIVER DISEASES

Abstract

Background:Chronic liver diseases whatever their etiologies could be associated with immunological disturbances.Objectives:Our aim was to evaluate the prevalence and the characteristics of autoimmune diseases associated with chronic liver diseases.Methods:We performed a retrospective analysis of data from consecutive patients followed in our department for chronic liver diseases recruited from January 2010 to December 2019. Demographic, clinical, and paraclinical data were collected.Results:A total of 224 patients were included. The mean age was 61.02 ±13.2 years and the sex-ratio was 1.6. The main etiology of chronic liver diseases was viral infection C (32.1%) followed by viral infection B (22.8%) and non-alcoholic steatohepatitis (21.4%). The prevalence of autoimmune chronic liver diseases was 7.58%: autoimmune hepatitis (AIH) in four cases, primary biliary cholangitis (PBC) in huit cases, primary sclerosing cholangitis (PSC) in three cases and overlap syndrome (AIH-PBC) in two cases. Autoimmune diseases were noted in 31 cases (13.9%): autoimmune hemolytic anemia in 15 cases, autoimmune thyroiditis in 12 cases, one case of psoriasis, one case of CREST syndrome, one case of Sjögren’s syndrome and one case of autoimmune thrombocytopenia. Autoimmune pathologies were more associated with autoimmune chronic liver disease than other causes of chronic liver disease (47% vs 11.1%, p <0.001). Autoimmune pathologies were not statistically associated with female gender (p = 0.085) or young age (p = 0.483).Conclusion:In our study, the prevalence of autoimmune diseases during chronic liver diseases was 13.9%. This prevalence was higher in the case of autoimmune chronic liver diseases (47%), which would underline the importance of systematic screening for clinical and biological immune manifestations in those patients.Disclosure of Interests:None declared
