Megjegyzések:Glycoprotein 2[GP2] is a specific target of pancreatic autoantibodies[PAbs] in Crohn's disease(CD) and is involved in gut innate immunity processes. Our aim was to evaluate the prevalence and prognostic potential of PAbs in primary sclerosing cholangitis(PSC). Sixty-five PSC patients were tested for PAbs by indirect immunofluorescence and compared with healthy (n=100) and chronic liver disease controls(CLD, n=488). Additionally, a panel of anti-microbial antibodies and secretory (s)IgA levels were measured, as markers of bacterial translocation and immune dysregulation. PAbs were more frequent in PSC (46.2%) compared to controls(healthy:0% and CLD:4.5%), P<0.001, for each]. Occurrence of anti-GP2 antibody was 30.8% (20/65) and was exclusively of IgA isotype. Anti-GP2 IgA positive patients had higher sIgA levels (P=0.021). With flow-cytometry, 68.4% (13/19) of anti-GP2 IgA antibodies were bound with secretory component, suggesting an active retro-transportation of anti-GP2 from the gut lumen to the mucosa. Presence of anti-GP2 IgA was associated with shorter transplant-free survival [PLogRank<0.01] during the prospective follow-up (median, IQR: 87 [9-99] months) and remained an independent predictor after adjusting for Mayo risk score (HR: 4.69 [1.05-21.04], P=0.043). These results highlight the significance of gut-liver interactions in PSC. Anti-GP2 IgA might be a valuable tool for risk stratification in PSC and considered as a potential therapeutic target.
