The aims of the present study were to detect anti\u20103\u2010PHGDH in patients with AIH and other chronic liver diseases and to analyze their clinical relevance.<\/jats:p><jats:p><jats:bold>Methods:\u2002<\/jats:bold> Human 3\u2010PHGDH gene was cloned and expressed in <jats:italic>Escherichia coli<\/jats:italic> and used in enzyme\u2010linked immunosorbent assays and Western blots. Serum from patients with AIH (<jats:italic>n<\/jats:italic>\u2003=\u2003101), primary biliary cirrhosis (PBC, <jats:italic>n<\/jats:italic>\u2003=\u2003122), chronic hepatitis C (CHC, <jats:italic>n<\/jats:italic>\u2003=\u2003117), chronic hepatitis B (CHB, <jats:italic>n<\/jats:italic>\u2003=\u2003112), and from patients with other autoimmune disease (<jats:italic>n<\/jats:italic>\u2003=\u2003125) were investigated.<\/jats:p><jats:p><jats:bold>Results:\u2002<\/jats:bold> The highest incidence and activity of anti\u2010PHGDH was observed in AIH patients. Thirty\u2010two of 40 untreated (80%) and 37 of 61 AIH patients treated with corticosteroid (60.7%) were positive. Antibody titers decreased significantly during corticosteroid treatment. 15.8% of PBC patients, 9.8% of CHB and 12.8% of CHC patients, were anti\u2010PHGDH\u2010positive, with less than 12% of patients positive with other autoimmune diseases via reactions with recombinant 3\u2010PHGDH protein.<\/jats:p><jats:p><jats:bold>Conclusion:\u2002<\/jats:bold> Anti\u2010PHGDH were detected in chronic liver diseases. They occur predominantly in AIH, and corticosteroid treatment seems to decrease antibody titers. Whether the antibodies are primary or secondary phenomena and whether they are related to the etiology or pathogenesis, at least in a subgroup of patients with chronic liver diseases, has still to be evaluated.<\/jats:p>","DOI":"10.1111\/j.1872-034x.2011.00839.x","type":"journal-article","created":{"date-parts":[[2011,6,30]],"date-time":"2011-06-30T13:07:16Z","timestamp":1309439236000},"page":"867-876","source":"Crossref","is-referenced-by-count":4,"title":["Detection
