This technique enabled us to look at antibodies reacting to \u2018pure\u2019 phospholipid antigens in the absence of protein contamination. Sera from 46 patients with IM, 18 with systemic lupus erythematosus (SLE), 21 with primary anti-phospholipid antibody syndrome (PAPS), 50 with Helicobacter pylori infection and 30 healthy blood donors were tested. This study highlights anti-phospholipid antibodies in patients with IM as specific \u2018pure\u2019 anti-cardiolipin antibodies, while in PAPS and SLE patients anti-phosphatidylserine and anti-phosphatidylethanolamine antibodies were also found. This investigation also shows that the anti-cardiolipin antibodies found in IM can be present with anti-cofactor protein antibodies. The higher prevalence of anti-cofactor antibodies found in IM sera than in Helicobacter pylori sera may be due to the immunostimulatory effect and\/or the polyclonal activation often observed in course of Epstein\u2013Barr virus infection. However, anti-\u03b22-GPI and, to a lesser extent, anti-prothrombin antibodies occur with a significantly lower prevalence in IM than in PAPS patients. This finding suggests that these antibodies should be regarded as the expression of the broad autoimmune syndrome involving the phospholipid-binding plasma proteins.<\/jats:p>","DOI":"10.1046\/j.1365-2249.2000.01206.x","type":"journal-article","created":{"date-parts":[[2003,3,11]],"date-time":"2003-03-11T10:21:27Z","timestamp":1047378087000},"page":"301-306","source":"Crossref","is-referenced-by-count":43,"title":["Specificity
