The most frequently hypothesized cause of unexplained recurrent pregnancy loss (RPL) refers to a defective maternal haemostatic response leading to uteroplacental thrombosis. Approximately 20% women suffering from pregnancy loss (PL) are associated with autoimmune disorders and more than 50% remain idiopathic after common traditional investigations. The present study aims to investigate the prevalence of different genetic and acquired thrombophilia markers in a large series of Indian women with RPL. Such studies will help analyze the markers which pose maximum risk and help in the appropriate treatment in subsequent pregnancies. The study comprised of 587 women with no apparent etiological causes of RPL and 115 healthy women controls. p values were calculated with two tailed Fisher's exact test; statistical significance was assumed at p<0. 05, 95% confidence interval. Relative risks were also calculated. Among genetic thrombophilia, the risk of PL was highest with protein S deficiency (16%, p=0. 006) followed by plasminogen activator inhibitor-1 4G/4G (23%, p=0. 007) polymorphism. Among acquired markers, the risk of PL was the highest in women with anti-cardiolipin antibodies (24%, p=0. 0001), followed by anti-annexin V antibodies (23%, p=0. 0009) and lupus anticoagulants (8%, p=0. 02). Thrombophilia, inherited and acquired, is an important contributing factor in unexplained RPL and should be screened in the order of its prevalence.
