title: [Antiphospholipid antibodies in systemic lupus erythematosus: study of a caseload of 120 patients].
abstract: In order to evaluate the presence of antiphospholipid antibodies (aPL) in patients with systemic lupus erythematosus (SLE), we measured IgG and IgM anticardiolipin antibodies (aCL) in a group of out- and in-patients of the Rheumatology Division at the Catholic University of Rome. Lupus anticoagulant and VDRL were also measured in 30 patients. One hundred thirteen women and 7 men (mean age 38.5 years, mean disease duration 4.27 years) were studied. The control group consisted of 60 age and sex matched healthy subjects. aCL IgG and IgM were positive in 48 (40%) and 49 (40.8%) patients respectively. aCL IgG correlated positively with the activated partial thromboplastin time. aCL IgM correlated positively with immunoglobulins of the G and M classes and with circulating immune complexes, and negatively with the C4 fraction. aCL antibodies did not correlate with spontaneous abortion or neurologic and psychiatric disturbances, although in women with a history of abortion, aCL IgG concentration was correlated with the number of spontaneous abortions. The presence of aPL does not seem to indicate a subgroup of SLE patients. The occurrence of abortion and/or neurologic and psychiatric disturbances in SLE seems to point to a complex pathogenesis with aPL as one of the causative agents.
