949 IDENTIFICATION OF TWO CLINICALLY DISTINCT SUBTYPES IN AUTOIMMUNE HEPATITIS BY COMPARATIVE FUNCTIONAL GENOMICS

2013

Conclusion: Incidence of autoimmune hepatitis is increasing, as other autoimmune diseases in developed countries. The main recognised hypothesis is the ‘hygienist theory’ (improvement of hygien leading to a decrease in infections) with few putative non exclusive mechanisms involving antigenic competition, extension of immune regulation induced by exogenous bacterial antigen or Toll Like Receptors.
