Seasonal distribution of antiphospholipid antibodies.

چکیده
BACKGROUND AND PURPOSE The purpose of this study was to determine if there was a seasonal variation in antiphospholipid antibody (aPL) titers and whether this variation differed between stroke cases and control subjects. METHODS IgG and IgM anticardiolipin and antiphosphatidyl serine antibody titers were obtained on serum samples from 884 stroke patients and 1024 control subjects over a 7-year period. Temporal distributions by month of blood draw were evaluated. RESULTS Marked seasonal differences in the proportion of positive titers were found for control subjects, but no seasonal variability among patients was noted. In control subjects, positive titers occurred less frequently in the summer months, mirroring the seasonal trends seen in respiratory track infections and rheumatic fever. CONCLUSIONS Our data suggest some aPL antibodies arise from different origins in patients and control subjects. The seasonality observed in the apparently normal population may be related to antibodies of infectious origin and is consistent with the reported lack of association with thrombosis of infection-related antibodies.

Comparison of Antiphospholipid Antibodies between Preeclamptsia and Normal Pregnant Women
Antiphospholipid antibodies (APLA) may be detected in normal pregnancies and also may cause thrombosis, recurrent fetal loss, placental infarction and preeclampsia. In the present study the possible differences in APLA titer between healthy pregnant women and preeclampsia cases without history of thrombosis was examined. The APLA titer in 50 healthy pregnant women with 50 preeclampsia cases wit...
