To study the association between early fetal loss and the presence of the PLA2 polymorphism of the ITGB3 gene we conducted a case-control study on 98 cases (i.e., women in fertile age, who experienced at least one episode of early fetal loss) and 38 healthy controls. PLA2 polymorphism was present in 44.2% of cases and 18.4% of controls, and cases with one (n = 24) event had an odds ratio (OR) = 2.7 (95% confidence interval [CI] 0.7-10.0), with two events (n = 52) an OR = 3.8 (95% CI 1.3-11.5), and with three (n = 16) or four abortions (n = 6) had a combined OR = 4.4 (95% CI 1.2-17.0), compared to controls, indicating that PLA2 polymorphism may be implicated in an inherited form of thrombophilia, and to early fetal loss.
