ABSTRACT Patients undergoing in vitro fertilization-embryo transfer have a high prevalence of anticardiolipin antibody (ACA). However, the relationship between ACA and IVF outcome is still controversial. The aim of the present study was to evaluate the potential effect of anticardiolipin antibody on IVF outcome and determine the role of adjuvant treatment in these ACA positive patients. The study included a total of 116 infertile women (116 IVF-ET cycles) positive for ACA, including 56 women pretreated with methylprednisolone plus low-dose aspirin before IVF (treated ACA+ group) and 60 patients without treatment (untreated ACA+ group). In addition, 518 infertile women (518 IVF-ET cycles) negative for ACA were enroled as controls (ACA- group). The results show that ACA+ patients who did not receive any adjuvant treatment showed a significantly lower fertilization rate, less high-quality embryos, as well as a markedly lower pregnancy rate and implantation rate than controls. Moreover, ACA+ patients who received methylprednisolone plus aspirin achieved significantly higher fertilization, pregnancy and implantation rates than untreated ACA+ patients (FR 69.0%, PR 46.4% and IR 25.4% vs. FR 60.0%, PR 33.3% and IR 17.9%, respectively). The overall IVF results in the treated ACA+ group were comparable to patients negative for ACA (PR 53.9% and IR 32.3%). Thus, while the presence of ACA exerts a detrimental effect on IVF outcome, ACA+ patients have a better outcome if given methylprednisolone for immunosuppression and low-dose aspirin as an anti-thrombotic agent.

    ABSTRACT: Pregnancy morbidity is one of the clinical manifestations used for classification criteria of antiphospholipid syndrome (APS). During the 14th International Congress on Antiphospholipid Antibodies (aPL), a Task Force with internationally-known experts was created to carry out a critical appraisal of the literature available regarding the association of aPL with obstetric manifestations present in actual classification criteria (recurrent early miscarriage, fetal death, preeclampsia and placental insufficiency) and the quality of the evidence that treatment(s) provide benefit in terms of avoiding recurrent adverse obstetric outcomes. The association of infertility with aPL and the effectiveness of the treatment of patients with infertility and positive aPL was also investigated. This report presents current knowledge and limitations of published studies regarding pregnancy morbidity, infertility and aPL, identifying areas that need better investigative efforts and proposing how critical flaws could be avoided in future studies, as suggested by participants of the Task Force. Except for fetal death, there are limitations in the quality of the data supporting the association of aPL with obstetric complications included in the current APS classification criteria. Recommended treatments for all pregnancy morbidity associated to APS also lacks well-designed studies to confirm its efficacy. APL does not seem to be associated with infertility and treatment does not improve the outcomes in infertile patients with aPL. In another section of the Task Force, Dr. Jane Salmon reviewed complement-mediated inflammation in reproductive failure in APS, considering new therapeutic targets to Obstetric APS (Ob APS).
