Antiphospholipid Antibodies in Iraqi Women with Recurrent Mid-Trimester Abortions

PURPOSE: Antiphospholipid antibodies are often associated with recurrent pregnancy loss, and although many studies have addressed this association in Western countries, such studies are not so frequent from developing countries. The current study aims to determine the frequency of Antiphospholipid antibodies (Anticardiolipin antibodies and Lupus anticoagulant) among Iraqi women with recurrent mid-trimester abortions and to evaluate various tests used for their detection. MATERIALS AND METHODS: Two hundred women with recurrent mid-trimester abortions were randomly enrolled from a main referral center in Baghdad-Iraq. The enrollees had their IgG and IgM anticardiolipin antibodies assayed by ELISA, and Lupus anticoagulant by a combination of the following screening tests : Activated Partial Thromboplastine Time (APTT), and Partial Thromboplastine Time-LA (PTT-LA), Kaolin Clotting Time (KCT) and confirmation was made by Hexagonal phospholipid neutralization test. RESULTS: The women were aged between 19 and 45 years (median 30 years). Fifty three (26.5%) had one or both anticardiolipin antibodies present, while 27 (13.5%) were positive for lupus anticoagulant. The KCT and KCT index appeared to be the most sensitive tests, while the KCT index and APTT were the most specific for Lupus anticoagulant. Patients with antiphospholipid antibodies had higher rates of history of thrombosis, thrombocytopenia and family history of recurrent abortion (P = 0.0009, 0.0056 and 0.0003 respectively). CONCLUSIONS: Antiphospholipid antibodies constitute an important cause of recurrent mid-trimester abortion in Iraqi women, with frequencies intermediate between Western and Indian reports. While thrombocytopenia and thrombosis are well documented associations of antiphospholipid antibodies, the significant association with family history of recurrent fetal loss is intriguing and requires further scrutiny.
