Antiphospholipid antibodies and pregnancy outcome of assisted reproductive treatment: A systematic review and meta-analysis. Am J Reprod Immunol 2021; 86:e13470. [PMID: 34018271 DOI: 10.1111/aji.13470] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 05/13/2021] [Accepted: 05/18/2021] [Indexed: 02/05/2023] Open
Abstract
PROBLEM Antiphospholipid antibodies (aPLs) are a group of autoantibodies associated with a variety of pregnancy complications, but the impact of aPL on the outcomes of assisted fertility treatment (ART) is controversial. This systematic review and meta-analysis were designed to explore the association between aPL and ART outcomes and to explore in which stages does aPL play a role. METHOD OF STUDY PubMed and Cochrane database were systematically retrieved, and odds ratios (ORs) or risk ratios (RRs) with 95% confidence intervals (CIs) were calculated in a random-effect model or fixed-effect model according to the heterogenicity assessed by the Cochran Q and I2 statistic test. Of 246 records identified by the search, 10 case-control studies and 13 cohort studies that explored the association between aPL and in vitro fertilization (IVF) and/or intracytoplasmic sperm injection (ICSI) were analyzed. RESULTS The results showed that aPL positive rate was higher in females who failed in IVF/ICSI than those who succeeded in IVF/ICSI (OR: 3.62, 95% CI: 1.95-6.74). This study also indicated that females positive for aPL have a higher miscarriage rate (RR: 1.68, 95% CI: 1.24-2.28) than those negative for aPL, but live birth rate, biochemical pregnancy rate, and clinical pregnancy rate were similar between two groups (RR: 1.01, 95% CI: 0.91-1.12; RR: 1.18, 95% CI: 0.57-2.43 and RR: 0.95, 95% CI: 0.80-1.13). CONCLUSIONS There was higher aPL prevalence in females with adverse IVF/ICSI outcomes. It seems that aPL mainly affects the miscarriage rate, but has little effect on live birth rate, biochemical pregnancy rate, and clinical pregnancy rate. Routine detection of aPL before IVF/ICSI treatment is meaningful.

Abstract
PROBLEM We investigated the beta2-glycoprotein I and anti-annexin V antibodies as anti-phospholipid-cofactor antibodies; and factor V G1691A Leiden, prothrombin G20210A, and methylenetetrahydrofolate reductase (MTHFR) C677T mutations as hereditary thrombophilia in recurrent pregnancy losses (RPL). METHOD OF STUDY Study group consisted of 84 women with recurrent pregnancy loss and control group consisted of 84 women having at least one live birth. RESULTS Methylenetetrahydrofolate reductase C677T homozygous mutation was detected in 28.5% of the study group and in 14.2% of the controls, and the difference was highly significant (P < 0.001). Heterozygous mutation of this gene was found in 64.3% of the study population and in 38.1% of the controls, and difference in heterozygous mutation frequency was also significant (P < 0.001). Both homozygous and heterozygous mutations of PT G20210A and factor V G1691A were not different between the groups. There was no significant difference in anti-annexin V levels and anti-beta2-gp 1 levels of the groups. CONCLUSION We concluded that both homozygous and heterozygous mutations of MTHFR C677T were related with RPL in Caucasian women.

Abstract
Abstract
Thrombophilia has been associated with pregnancy complications and recurrent miscarriage. The aim of this systematic review was to evaluate the controversial association between thrombophilia and failures of assisted reproduction technology (ART). A systematic search of the literature for studies reporting on thrombophilia in women undergoing ART up to April 2011 yielded 33 studies (23 evaluating anti-phospholipid antibodies, 5 inherited thrombophilia, and 5 both) involving 6092 patients. Overall, methodologic quality of the studies was poor. Combined results from case-control studies showed that factor V Leiden was significantly more prevalent among women with ART failure compared with fertile parous women or those achieving pregnancy after ART (odds ratio = 3.08; 95% confidence interval, 1.77-5.36). The prothrombin mutation, methylenetetrahydrofolate reductase mutation, deficiency of protein S, protein C, or anti-thrombin were all not associated with ART failure. Women with ART failure tested more frequently positive for anti-phospholipids antibodies (odds ratio = 3.33; 95% confidence interval, 1.77-6.26) with evidence of high degree of between-study heterogeneity (I2 = 75%; P < .00001). Prospective cohort studies did not show significant associations between thrombophilia and ART outcomes. Although case-control studies suggest that women experiencing ART failures are more frequently positive for factor V Leiden and anti-phospholipid antibodies, the evidence is inconclusive and not supported by cohort studies.

Abstract
Antiphospholipid antibodies, i.e. lupus anticoagulants and anticardiolipin antibodies, are associated with obstetric complications. Fetal death and recurrent spontaneous abortions represent the obstetric criteria of the antiphospholipid syndrome. They occur with similar frequences and have an overall prevalence of 15-20%. Lupus anticoagulants carry a risk 3.0 to 4.8 times, and anticardiolipin antibodies 0.86 to 20 times higher than controls. The mechanism(s) by which antiphospholipid antibodies cause these events still has to be defined: thrombosis in the placental vessels, and impairment of embryonic implantation have been proposed. Unfractionated or low-molecular-weight heparin, alone or in combination with low-dose aspirin, represent the current standard treatment of pregnant antiphospholipid-positive women for preventing recurrent obstetric complications. Upon treatment, the live birth rate increases from 0-40% to 70-80%. However, there is still an excessive frequency of maternal and/or fetal complications, indicating the necessity of a better calibration of the dosage, duration and timing of administration of heparin treatment.

Abstract
PURPOSE OF REVIEW Much attention has been paid to the role of immunology in reproductive success or failure. Every step in the establishment of normal pregnancy has been implicated as a possible site of immune-mediated reproductive failure. The widespread testing of antiphospholipid, antinuclear, antithyroid, and antisperm antibodies, as well as generalized immune testing, have thus been employed to diagnose patients with otherwise unexplained infertility or recurrent pregnancy loss. Controversial data surrounding the widespread and variable use of immune testing in current fertility practice is reviewed to determine which tests are warranted based on sound scientific evidence. Because it is postulated that early miscarriage, when occult, could represent a failure of embryo implantation indistinguishable from unexplained infertility, this analysis of immune testing includes a discussion of patients with recurrent pregnancy loss. RECENT FINDINGS Despite the increased prevalence of abnormal immune testing associated with early reproductive failure, the most rigorous studies have not proven a cause and effect between these phenomena. There is wide variation and inconsistency regarding this association, depending upon which test(s) are employed, the study methodology used, and the patient population under study. The significance of selected immunological test abnormalities associated with early reproductive failure is uncertain. SUMMARY Great variability exists in identifying candidates for immune testing, determining which tests to order, interpreting the test results, and offering immunologic treatments. This review argues that the use of widespread immune testing in clinical practice can not be supported by existing data. The resulting therapies are similarly of unconfirmed benefit and may cause harm.

Abstract
OBJECTIVE To document the clinical association between the history of pregnancy loss in patients with the diagnosis of primary or secondary antiphospholipid syndrome (APS) and the presence of different antiprothrombin antibody subtypes [immunoglobulin G (IgG), IgM and IgA] in a cohort of patients with APS. METHODS Records of 170 female patients with primary APS, or APS secondary to systemic lupus erythematosus (SLE) or secondary to other autoimmune diseases were studied. RESULTS In female APS patients with IgG antiprothrombin antibodies (n = 105) significant associations to pregnancy loss (p < 0.0001), early pregnancy loss (p < 0.0001) and a negative association to thrombocytopenia (p < 0.01) could be identified. In the group of patients with IgG antiprothrombin antibodies and at least one pregnancy (n = 84) a significant association with pregnancy loss (p < 0.005) and especially with early pregnancy loss (p < 0.0001) was demonstrated. No association with other immunoglobulin subtypes of antiprothrombin antibodies could be documented. In the subgroup of patients with primary APS and at least one pregnancy in the history, pregnancy loss (p < 0.005) and early pregnancy loss (p < 0.0001) were found to be highly associated with the presence of IgG antiprothrombin antibodies. IgG antiprothrombin antibodies represent the highest independent risk factor for pregnancy loss with an odds ratio of 4.5. There was no statistically significant association with venous or arterial thrombosis in all IgG antiprothrombin antibody positive patients. CONCLUSION The results of this study document the association of IgG antiprothrombin antibodies with pregnancy loss and in particular early pregnancy loss in a large and well-characterized cohort of patients. We would recommend routine testing for antiprothrombin antibodies in young female patients with APS.

Abstract
True (cofactor-independent) anticardiolipin antibodies (aCL) are thought to lack lupus anticoagulant (LA) activity and pathogenic potential. A serum monoclonal immunoglobulin Mlambda (mIgMlambda) with aCL and LA activities found in a man with a splenicIgMlambda+ B-cell lymphoplasmacytic lymphoma (LPL) without thrombotic events has been characterized. LPL-derived hybridoma clones (designated HY-FRO) producing the serum mIgMlambda were obtained. mIgMlambda secreted by HY-FRO grown in protein-free culture medium, like that purified from serum, (i) showed binding, in a cofactor-free system, to solid-phase CL and phosphatidylserine (PS) and to the membrane of PS-expressing cells (apoptotic cells and activated platelets); (ii) failed to bind neutral phospholipids (PL), beta2Glycoprotein, histone, ssDNA, dsDNA, human IgG and umbilical vein endothelial cells. Absorption with apoptotic cells abolished its binding to anionic plate-bound CL and PS. IgMlambda-FRO used poorly mutated VH and Vlambda region genes, with a pattern that was inconsistent with an antigen-driven selection. Basic amino acids were present in the IgH complementarity determining region 3 (CDR3), which can be important for binding to anionic PL. These findings demonstrate unequivocally that true anti-anionic PL IgM antibodies can exert LA and indicate this anti-PL type does not involve thrombophilia.

Abstract
The present review highlights recent studies that investigated the possible influences of autoimmune factors in reproductive success or failure. These factors include antiphospholipid antibodies, antithyroid antibodies, antinuclear antibodies, antisperm antibodies, and antiovarian antibodies. The majority of recent work has focused on these potential autoimmune factors; however, controversy still exists over indicated testing and treatment options. An association of antiphospholipid antibodies and recurrent pregnancy loss has been established, and treatment with subcutaneous heparin appears most efficacious. Other autoimmune factors are under investigation as markers of in-vitro fertilization failure. Limited data from treatment trials are presented.

Abstract
Sixty percent of recurrent spontaneous abortions are unexplained. Antiphospholipid syndrome is a multisystem disease with the predominant features of venous and arterial thrombosis, recurrent pregnancy loss, foetal death and the presence of antiphospholipid antibodies. Many epidemiological studies focus on antiphospholipid autoantibodies syndrome (APS) as a cause of recurrent spontaneous abortion (RSA). It is found that 7-25% of RSA would have APS as the main risk factor. 'Association not being synonymous with cause', the proportion of abortions due to the APS is difficult to estimate for several reasons: definition of recurrent abortion is variable, the assays for antiphospholipid antibodies are not well standardised, inclusion of patients in the study group according to the antibodies titre is author dependent. Recent studies suggest association of antiphospholipid antibodies syndrome not only with recurrent abortions but also with infertility. New mechanisms are described by which antiphospholipid antibodies could cause placental thrombosis and infarction, acting directly on the surface anticoagulant expressed on trophoblastic cells. Only lupus anticoagulant (LA) and anticardiolipin antibodies (aCL) assays are sufficiently standardised to be usable in routine. Testing for other antiphospholipid antibodies (aPLs) should remain investigational. Several treatments have been proposed: low doses of aspirin, low or immunosuppressive doses of corticosteroids, and preventive or effective dose of heparin, intravenous immunoglobulin.

Abstract
The obstetric management of women with antiphospholipid (aPL) syndrome remains controversial. Despite recent advances, the controversies have been fueled by our limited understanding of the multi-factorial causes of aPL-associated pregnancy loss and the lack of data from randomized studies. We have escaped from the narrow confines of the concept of aPL pregnancy loss being purely thrombotic in aetiology and attention is now focused on the adverse effects of aPL on embryonic implantation and trophoblast invasion. Combined treatment with aspirin and heparin has been demonstrated in two randomized studies to lead to a high live birth rate in aPL pregnancies. However, successful pregnancies are characterized by a high rate of perinatal complications and some women are refractory to this treatment combination. In addition to addressing these issues, multi-centre studies, which should perhaps be internet based, are needed to identify those aPL that are causative of pregnancy complications and those that are not, the role of IVIG and the long-term follow-up of both mothers with aPL and their babies.

Abstract
The diagnosis of antiphospholipid syndrome (APS) requires the presence of both clinical and biological features. Due to the heterogeneity of anti-phospholipid antibodies (aPL) the laboratory approach for their detection includes clotting-based tests for lupus anticoagulant (LA) as well as solid-phase assays for anticardiolipin antibodies (aCL). In addition, as it has been shown that autoimmune aPL recognize epitopes on phospholipid (PL)-binding plasma proteins, assays detecting antibodies to beta 2-glycoprotein I (beta 2-GPI) or prothrombin have been developed. The association between venous or arterial thrombosis and recurrent fetal loss with the presence of conventional aPL (LA and/or aCL) has been confirmed by many studies. The LA and IgG aCL at moderate/high titre seem to exhibit the strongest association with clinical manifestations of the APS. Several reports indicate that LA is less sensitive but more specific than aCL for the APS. Assays against PLs other than CL as well as the use of mixtures of PLs have been proposed to improve the detection of APS-related aPL. Concerning antibodies to PL-binding proteins (detected in the absence of PLs), there is evidence that anti-beta 2-GPI are closely associated with thrombosis and other clinical features of the APS. Moreover, these antibodies may be more specific in the recognition of the APS and in some cases may be present in the absence of aPL detected by standard tests. Many issues are still under debate and are discussed in this review, such as the problems of standardization of anti-beta 2-GPI assays, detection of the IgA isotype of aCL and anti-beta 2-GPI, the coagulation profiles of LA in the recognition of the thrombotic risk and the association of particular markers with subsets of patients with APS.
