In order to determine the prevalence and clinical significance of beta 2-GPI-dependent anticardiolipin antibodies (beta 2-GPI/aCL) in patients with systemic sclerosis (SSc), serum samples from 80 patients with SSc, 20 patients with systemic lupus erythematosus (SLE), and 120 healthy control subjects were examined by ELISA using purified beta 2-GPI. IgG isotype beta 2-GPI/aCL was present in eight of 80 patients with SSc (10%), and the presence of beta 2-GPI/aCL IgG was significantly correlated with the presence of isolated pulmonary hypertension (PH). Furthermore, levels of beta 2-GPI/aCL IgG were significantly correlated with levels of mean pulmonary arterial pressure. These data suggest that IgG isotype beta 2-GPI/aCL might be a serological indicator of the severity of PH in patients with SSc.

Antiphospholipid Syndrome (APS) was first described by Hughes and sometimes called as Hughes syndrome. Recent studies revealed that the antigen to anticardiolipin antibody (aCL) is not cardiolipin itself but co-factor beta 2-GPI which expresses its epitope when it combines cardiolipin or gets oxidized. Lupus Anticoagulant is now possibly considered as anti-prothrombin antibody. Livedo including Snedden syndrome, pulmonary hypertension and skin ulcer became considered as the part of symptoms of this disease. In ISAPA 1998, it is reported from several laboratories that IgA aCL is also pathogenic to thrombosis as well as IgG aCL. Atherosclerosis is also accelerated by aCL. Catastrophic APS is rare but fatal, reported 3 cases in Japan and 50 cases in the world.
