Modulation of the activation of endothelial nitric oxide synthase and nitrosative stress biomarkers by aspirin triggered lipoxins: A possible mechanism of action of aspirin in the antiphospholipid syndrome.

Abstract
PROBLEM Antiphospholipid syndrome (APS) is characterized by the clinical manifestation of vascular thrombosis (VT) or pregnancy morbidity (PM) and antiphospholipid antibodies (aPL) that can modify the nitric oxide production. Low-dose aspirin is used in the prevention and treatment of diverse alterations of pregnancy. One of the mechanisms of action of aspirin is to induce the production of aspirin-triggered-lipoxins (ATL). The aim of this study was to evaluate the modulatory effect of ATL over the activation of endothelial nitric oxide synthase (eNOS) and nitrosative stress biomarkers induced by aPL. METHODS We used polyclonal IgG and sera from women with aPL and PM/VT or VT only, and from women with PM only and positive for non-criteria aPL (SN-OAPS). In these sera, biomarkers of nitrosative stress (nitrites and nitrotyrosine) were measured. The protein expression of nitrotyrosine and the phosphorylation of eNOS (at Ser1177) were estimated in human umbilical vein endothelial cells (HUVECs) stimulated with polyclonal IgG with or without ATL. RESULTS Women with SN-OAPS showed increased circulating levels of nitrites and nitrotyrosine. Likewise, polyclonal IgG from either SN-OAPS or VT patients stimulated nitrotyrosine expression in HUVECs. ATL decreased the nitrotyrosine expression induced by polyclonal IgG from the SN-OAPS group. ATL also recovered the reduced eNOS phosphorylation at Ser1177 in HUVECs stimulated with polyclonal IgG from women with PM/VT or SN-OAPS. CONCLUSIONS Increased nitrosative stress present in serum of women with SN-OAPS is associated with IgG-mediated impaired endothelial NO synthesis in endothelial cells. ATL prevent these cellular changes.

Antinuclear antibodies positivity in women in reproductive age: From infertility to adverse obstetrical outcomes - A meta-analysis. J Reprod Immunol 2023; 155:103794. [PMID: 36621091 DOI: 10.1016/j.jri.2022.103794] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2022] [Revised: 12/13/2022] [Accepted: 12/29/2022] [Indexed: 01/05/2023]
Abstract
This systematic review and meta-analysis were designed to identify possible correlations between isolated serum antinuclear antibody (ANA) and (i) infertility in the context of in-vitro fertilization (IVF), (ii) idiopathic recurrent pregnancy losses (RPL), and (iii) second/ third trimester pregnancy complications. We performed a systematic review and meta-analysis of the literature in PubMed Library database from inception to March 2022 following PRISMA guidelines. Our pooled results showed a lower pregnancy rate among ANA-positive women undergoing IVF/ICSI compared to ANA-negative women undergoing the same procedures (279/908 versus 1136/2347, random effect, odds ratio -OR- 0.50, 95% confidence interval -CI- 0.38-0.67, p 0.00001, I2 = 58%). We also reported a higher miscarriage rate among ANA-positive compared to ANA-negative women (48/223 versus 109/999, random effect, OR: 3.25 95% CI: 1.57-6.76, p = 0.002, I2 = 61%) and a lower implantation rate (320/1489 versus 1437/4205, random effect, OR: 0.51, 95% CI: 0.36-0.72, p = 0.0001, I2 = 78%). Regarding RPL, pooled results demonstrated a higher prevalence of ANA-positivity in RPL women compared to controls (698/2947 versus 240/3145, random effect, OR: 3.22, 95% CI: 2.12-4.88, p 0.00001, I2 77%), either using > 2 or > 3 pregnancy losses threshold for defining RPL. Heterogeneity of reporting outcome did not allow a quantitative analysis and led to no clear demonstration of an effect of serum ANA on the incidence of stillbirth, preeclampsia and hypertensive disorders. In conclusion, the unfavorable effect of serum ANA was observed in women following IVF. Similarly, ANA were associated with the risk of RPL, while data were unconclusive in terms of late pregnancy complications.

Extracellular vesicles released upon stimulation with antiphospholipid antibodies: An actual direct procoagulant mechanism or a new factor in the lupus anticoagulant paradox? J Autoimmun 2022; 133:102905. [PMID: 36115210 DOI: 10.1016/j.jaut.2022.102905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Revised: 08/19/2022] [Accepted: 08/26/2022] [Indexed: 12/13/2022]
Abstract
Antiphospholipid antibodies (aPL) lead to a hypercoagulable state in vivo. Paradoxically, some of these autoantibodies perform as inhibitors of the coagulation cascade in vitro (a phenomenon referred to as "lupus anticoagulant"). The presence of lupus anticoagulant has been related to an increased quantity of plasma extracellular vesicles, which may constitute a direct procoagulant mechanism in antiphospholipid syndrome. This study investigates whether or not endothelial cell-derived extracellular vesicles released upon stimulation with aPL (aPL-EDEVs) are related to a higher direct coagulation activity. Using an in vitro model of endothelium, flow cytometry and a recalcified plasma-based assay, we found that the coagulation activity of aPL-EDEVs is mainly conditioned by the lupus anticoagulant-like activity of autoantibodies. Nevertheless, in the presence of β2 glycoprotein I, a cofactor of aPL during the stimulation of endothelial cells, the coagulation activity of EDEVs is restored in a mitogen-activated protein kinase kinases 1 and 2 (MEK1/2)-dependent manner. This phenomenon was especially evident when using immunoglobulins G from patients with vascular and obstetric primary antiphospholipid syndrome who manifest refractoriness to treatment. Our findings suggest that the role of aPL-EDEVs in the antiphospholipid syndrome-related hypercoagulable state may not rely on their capacity to enhance clotting directly. While β2 glycoprotein I performs as a procoagulant cofactor and restores the coagulation activity of extracellular vesicles via MEK1/2 pathway, proportionally, autoantibodies interact with aPL-EDEVs and exhaust their coagulation properties. Further analysis is required to establish whether lupus anticoagulant-like autoantibodies opsonise extracellular vesicles and whether opsonised vesicles may lead to thrombosis by indirect means.

Abstract
In the past decade, the incidence of recurrent pregnancy loss (RPL) has increased significantly, and immunological disorders have been considered as one of the possible causes contributing to RPL. The presence of antinuclear antibodies (ANAs) is regarded as a typical antibody of autoimmunity. However, the relationship between the presence of ANAs and RPL, the underlying mechanism, and the possible role of immunotherapy is still controversial. The aim of this mini review is to assess the association between ANAs and RPL and the effects of immunotherapy on pregnancy outcomes in women with positive ANAs and a history of RPL from the available data and to provide a relevant reference basis for clinical application in this group of women.

Abstract
Antiphospholipid syndrome (APS) is an autoimmune disease characterized by thrombosis and pregnancy morbidity (PM) obstetric events together with persistent high titers of circulating antiphospholipid antibodies (aPL). Several mechanisms that explain the development of thrombosis and PM in APS include the association of aPL with alterations in the coagulation cascade and inflammatory events. Other mechanisms disturbing cellular homeostases, such as mitochondrial dysfunction, autophagy, and cell proliferation, have been described in other autoimmune diseases. Therefore, the objective of this study was to investigate the impact of aPL from different patient populations on endothelial cell mitochondrial function, activation of the mammalian target of rapamycin (mTOR) and autophagy pathways, and cellular growth. Using an in vitro model, human umbilical vein endothelial cells (HUVECs) were treated with polyclonal immunoglobulin G (IgG) purified from the serum of women with both PM and vascular thrombosis (PM/VT), with VT only (VT), or with PM and non-criteria aPL (seronegative-obstetric APS, SN-OAPS). We included IgG from women with PM without aPL (PM/aPL-) and healthy women with previous uncomplicated pregnancies (normal human serum, NHS) as control groups. Mitochondrial function, mTOR activation, autophagy, and cell proliferation were evaluated by Western blotting, flow cytometry, and functional assays. IgG from women with PM/VT increased HUVEC mitochondrial hyperpolarization and activation of the mTOR and autophagic pathways, while IgG from patients with VT induced endothelial autophagy and cell proliferation in the absence of elevated mTOR activity or mitochondrial dysfunction. IgG from the SN-OAPS patient group had no effect on any of these HUVEC responses. In conclusion, aPL from women with PM and vascular events induce cellular stress evidenced by mitochondrial hyperpolarization and increased activation of the mTOR and autophagic pathways which may play a role in the pathogenesis of obstetric APS.

Abstract
This study investigated if immunomodulatory treatment improves the in-vitro fertilization (IVF) success rates of women with two or more recurrent pregnancy losses (RPL) and repeated implantation failures (RIF) with cellular immune abnormalities and thrombophilia. We performed a retrospective cohort study of 197 RPL patients who received immunomodulatory and anticoagulation treatment undergoing IVF cycles (fresh or frozen embryo transfer). Patients were divided into four groups; Group 1: women with RPL but without RIF, Group 2: women with RPL and RIF (≥3), Group 3: women with RPL after IVF cycles (>2) and without RIF, and Group 4: women with RPL after IVF cycles and RIF. Patients received immunomodulatory treatment with prednisone-only or prednisone and intravenous immunoglobulin G (IVIG) and anticoagulation treatment with low molecular weight heparin and low dose aspirin. IVF success rates of study groups were compared to those of the historical controls. The pregnancy rate of IVF cycles with immunomodulatory treatment was significantly increased in all patients (48.2 % vs. 33.0 %, P < 0.001), Group 1 (54.2 % vs. 30.5 %, P < 0.005) and Group 2 (33.3 % vs. 11.0 %, P < 0.005) as compared to historical controls. The live birth rates per ET cycle were significantly improved for all patients (1.8 % vs. 39.6 %, P < 0.001), and study groups compared to their historical controls (Group 1, 43.1 % vs. 0 %; Group 2, 33.3 % vs. 2.5 %; Group 3, 45.5 % vs. 2.3 %; and Group 4, 16.7 % vs. 1.2 %, P < 0.001, respectively). Immunomodulatory and anticoagulation treatment significantly improved the reproductive outcomes of IVF cycles in women with a history of RPL and/or RIF of immune etiologies.

Abstract
OBJECTIVE Immunologic mechanisms have been proposed as part of the pathogenesis mechanisms involved in recurrent pregnancy loss (RPL). Presence of positive antinuclear antibodies (ANA) is regarded as a typical feature of autoimmunity. Many studies had tried to clarify the association of ANA with RPL, but the conclusions were controversial. The aim of this meta-analysis was to assess whether ANA was positively associated with increased RPL risk. METHODS We searched PubMed and Embase databases for relevant literatures on the association between ANA positivity and RPL. The odds ratios (OR) with 95% confidence intervals (95%CI) were pooled using meta-analysis, and either fixed-effect or random-effect model was used based on heterogeneity across the included studies. RESULTS Twenty-one studies with 5038 participants (including 2683 RPL patients and 2355 controls) met the inclusion criteria were included. The total positive rate of ANA was 22.0% (591/2683) in RPL group, and 8.3% (196/2355) in the control group. RPL patients had a significantly higher ANA positive rate than controls (OR = 2.97, 95%CI 1.91-4.64, P<0.00001; I² = 75%), and a significant association between positive ANA and unexplained RPL was also observed (OR = 3.27, 95%CI 2.01-5.31, P<0.00001; I² = 70%). ANA positivity was also significantly associated with increased risk of RPL in women without defined autoimmune diseases (OR = 2.23, 95%CI 1.40-3.55, P=0.0007). Subgroup analysis demonstrated low titers of ANA (1:40≤ANA≤1: 80) were not associated with RPL (OR = 2.44, 95%CI 0.42-14.06, P=0.32), while higher ANA titer (≥1:160) had a significant association with RPL (OR = 45.89, 95%CI 8.44-249.45, P<0.00001). A higher rate of homogenous pattern in RPL patients was observed (OR = 4.89, 95%CI 2.20-10.87, P<0.001), and no significant difference in speckled pattern or nucleolar pattern was found. CONCLUSIONS This study demonstrated that ANA positivity was positively associated with increased RPL risk. ANA positivity is an important risk factor for RPL which needed to be screened among women with RPL.

Abstract
Studies have investigated the relationship between antinuclear antibodies (ANA) and recurrent miscarriage (RM). The objective of this paper is to evaluate the presence of ANA as a risk factor for spontaneous abortion in patients with RM. By considering the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis, the authors performed systematic review and meta-analysis by searching the databases of PubMed/Medline and SCOPUS. Review Manager, Version 5.3 performed the statistical analysis. Binary variables were analyzed by odds ratio (ORs) and 95% confidence interval (CI). The subgroup analysis compared the effect of different ANA titers. The authors analyzed the ANA patterns of immunofluorescence staining. Seven case-control studies were selected. The frequency of positive ANA was statistically higher in the RM group (20.6%, 288/1400) as compared to the control group (6.7%, 72/1080). The meta-analysis of the positive ANA showed a statistical difference between the two groups (OR 3.30, 95% CI 1.41-7.73; I2 = 87%, P = .006). Studies have revealed different frequencies of ANA patterns of immunofluorescence. This meta-analysis suggested that positive ANA might increase the risk of RM. However, it was not possible to conclude which ANA pattern of immunofluorescence staining is more frequent in the RM group.

Abstract
Introducción. El síndrome antifosfolípido se caracteriza por la presencia persistente de anticuerpos antifosfolípidos y manifestaciones clínicas de trombosis o morbilidad gestacional, las cuales se asocian con estrés oxidativo y disfunción endotelial. Objetivo. Evaluar los marcadores de estrés oxidativo en células endoteliales, inducidos por el suero de mujeres con diferentes manifestaciones clínicas del síndrome antifosfolípido y analizar la capacidad antioxidante de los sueros. Materiales y métodos. Se incluyeron 48 mujeres que fueron clasificadas así: presencia de anticuerpos antifosfolípidos y criterios clínicos de morbilidad gestacional, trombosis vascular o ambas. Como grupos control se incluyeron mujeres negativas para anticuerpos antifosfolípidos. En un modelo in vitro de células endoteliales estimuladas con los sueros de las mujeres del estudio, se determinaron algunos marcadores de estrés oxidativo por citometría de flujo. También, se analizó la capacidad antioxidante de los sueros incluidos. Resultados. Los sueros de los grupos de mujeres con síndrome antifosfolípido que presentaban trombosis, con morbilidad gestacional o sin ella, generaron un incremento significativo (p<0,05 y p<0,001) en los marcadores de estrés oxidativo endotelial, en contraste con el control de suero humano normal. No se observaron diferencias en el efecto de los sueros de los diferentes grupos de estudio sobre la lipoperoxidación endotelial. Tampoco se encontró diferencia en la actividad antioxidante de los sueros. Conclusión. El estrés oxidativo mitocondrial en el endotelio se asocia con la presencia de trombosis. Sin embargo, cuando esta se asocia con morbilidad gestacional, también se genera estrés oxidativo intracelular.

Abstract
PROBLEM Women with antiphospholipid antibodies (aPLs) present a risk of pregnancy morbidity (PM), vascular thrombosis (VT), or both (PM/VT). aPLs affect trophoblast function, and the aim of this study was to determine the modulation of this aPL-induced damage by different drugs. METHOD OF STUDY IgG was obtained from women with PM and PM/VT positive to aPLs. Binding of IgG to trophoblastic cells, proliferation, mitochondrial membrane integrity, and trophoblast invasion were assessed. The effect of enoxaparin, aspirin, and aspirin-triggered lipoxin (ATL) were evaluated as well as signal transducer and activator of transcription 3 (STAT3) phosphorylation. RESULTS IgG from women with aPLs strongly binds to trophoblastic cells. Integrity of mitochondrial membrane was reduced, and proliferation was increased by IgG-PM/VT. Both IgG-PM and IgG-PM/VT decreased trophoblast invasion, which was restored by enoxaparin, aspirin, and ATL. IgG-PM triggered reduction in STAT3 phosphorylation. CONCLUSION Some drugs used to prevent aPL-induced PM modulated the alteration of trophoblast function.

Abstract
The relationship between miscarriage and fertility is complex. While most healthcare settings treat miscarriage as a problem of subfertility in assisted reproduction units, others believe that miscarriage occurs in super-fertile women. Infertile women undergoing assisted reproduction are at a greater risk of having a miscarriage especially at an advanced age compared with women conceiving naturally. Aberrant expression of immunological factors and chromosomal abnormalities underlie both infertility and miscarriage. Common risk factors include increased maternal age, obesity, smoking, alcohol, pre-existing medical conditions and anatomical abnormalities of the reproductive system. Management pathways of both conditions may be similar with pre-implantation genetic testing and assisted reproductive technology used in both conditions. This paper discusses the synergies and differences between the two conditions in terms of their epidemiology, etiopathogenesis, risk factors and management strategies. The two conditions are related as degrees of severity of reproductive failure with common pathways in manifestation and management.

Abstract
Antiphospholipid antibodies (aPls) are generally characterized as heterogeneous and non-specific autoantibodies directed against various phospholipids such as cardiolipin, ph-serine, ph-inositol, ph-acid, ph-glycerol, ph-sphyngomyelin, ph-choline, annexins, and co-factor β2-glycoprotein I. aPls occur not only during autoimmune diseases but also during infectious diseases, essential hypertension, neurological complication, metabolic diseases, some drug abuse, and transplant loss. aPls are very often found in connection with reproductive failure such as repeated pregnancy loss and/or missed abortion, intrauterine fetal death, in preeclampsia, and repeated delivery of hypothrophic fetus. The presence of aPls, thrombosis, and fertility failure create primary or secondary antiphospholipid syndrome. This article explains some aspects and clinical and laboratory significance of the aPls in female infertility.

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 lack 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).

Abstract
Antiphospholipid antibodies (aPL) have been associated with recurrent pregnancy losses (RPL) and other obstetrical complications. The diagnostic criteria for the classical antiphospholipid antibody syndrome (APS) have been utilized for the detection of obstetrical APS in women with RPL. However, laboratory findings and immunopathology of obstetrical APS are significantly different from those of classical APS. In addition, many women with RPL who have positive aPL do not have symptoms consistent with the current APS criteria. The induction of a proinflammatory immune response from trophoblasts and complement activation by aPL rather than thromboembolic changes has been reported as a major immunopathological feature of obstetrical APS. Heparin treatment has been reported to be effective in prevention of early pregnancy loss with APS but not for the late pregnancy loss or complications. The complex effects of heparin may explain the limited efficacy of heparin treatment in RPL. New diagnostic criteria for obstetrical APS are needed urgently, and new therapeutic approaches should be explored further.

Abstract
PROBLEM To investigate the possibility that antinuclear antibodies (ANA) are involved in recurrent pregnancy loss (RPL). METHODS Case-control study carried out on 294 women (194 cases and 100 controls) in two University hospitals. The presence, the serum titers and the indirect immunofluorescence (IIF) patterns of ANA were determined in women with RPL and in control women. RESULTS Antinuclear antibodies at titers ≥ 1:80 were detected in 97 (50%) women with RPL and in 16 (16%) control women. Elevated ANA titers (≥1:180) were detected only in RPL women, whereas all control women had ANA titers no greater than 1:80. No differences could be detected in the IIF patterns between RPL and control women. No differences in ANA positivity could be detected according to the type (primary or secondary) or number (>2 versus ≥3) of losses. CONCLUSIONS ANA could be of some value in identifying women with RPL with potential, although still not fully defined, immune abnormalities.

Abstract
In a prospective comparative study we screened 112 women with a past history either of pre-eclampsia, eclampsia, recurrent abortion, IUGR, IUFD or abruptio placentae, with no apparent aetiology and a demographically matched cohort of 106 women having a past history of uncomplicated pregnancy outcome for the presence of antiphospholipid antibodies (aPL) and their significance. In the former group, the prevalence of aPL ranged from 10-46.87% compared with 8.49% in the later group. In women with the presence of aPL, the incidence of pre-eclampsia, early onset pre-eclampsia and abruptio placentae were 25%, 14.58% and 18.75%, respectively. In the same group, the abortion rate was 25% and live-birth rate was 64.58% with IUFD rate of 10.42%. Fetal morbidity rates were also higher in the mothers with aPL positivity, the incidence of IUGR was 27.08% and oligohydramnios was 33.33% in them. All these complications were statistically significant when compared with those of aPL negative mothers.

Abstract
PROBLEM An immune-based aetiology is one of the several accepted causes for recurrent foetal loss (RFL). However, most of the immunological theories have not fulfilled the criteria for causality. This is a review of the various immunological causes of RFL and the outcome of different treatment protocols. METHOD OF STUDY Both auto- and alloimmune maternal immunological abnormalities have been proposed to account for foetal loss. Among the autoimmune factors, anti-phospholipid antibodies (APAs) have been demonstrated to be the strongest risk factors for foetal loss, the prevalence of which is as high as 40% in women with RFL. Other autoimmune antibodies implicated in RFL are anti-nuclear antibodies (ANAs), anti-thyroid antibodies and anti-endothelial cell antibodies. The alloimmune factors implicated in pregnancy loss of unknown aetiology include abnormal natural killer (NK) cell activity, alteration in T helper 1 (Th1) and T helper 2 (Th2) ratios, presence of alloimmune antibodies like anti-paternal cytotoxic antibodies, anti-idiotypic antibodies, mixed lymphocyte reaction blocking antibodies and abnormal expression of HLA-G molecules. Management of patients with RFL is mainly based on immunomodulatory (prednisolone, intravenous immunoglobulins, plasma exchange, paternal lymphocyte therapy), anti-aggregation (aspirin) or anti-coagulation (unfractionated or low molecular weight heparin) agents. RESULTS Low-molecular-weight heparin with low-dose aspirin has been found to be the most effective treatment for women with APAs and RFL. Differences in dosage, timing of treatment, inclusion criteria, outcome assessment parameters etc. are some of the factors which have resulted in discrepancies in various reports. CONCLUSION Identification of the immunological mechanisms involved in pregnancy loss and the action of different therapeutic reagents is important so that effective therapies can be designed and investigated.

Abstract
PROBLEM To determine the presence or absence of subclinical autoimmunity in Caucasian Argentine healthy women with first trimester recurrent pregnancy loss (RPL), the sera of 118 healthy women with a history of three or more consecutive abortions and 125 fertile control women without abortions and two children were analyzed for the presence of autoantibodies: immunoglobulin (Ig)G and IgM anticardiolipin, antinuclear (ANA), antismooth muscle (ASMA), antimitocondrial (AMA), antiliver-kidney-microsomal fraction (LKM), antigastric parietal cells (GPC), antineutrophil cytoplasmatic (ANCA) and antibodies antigliadin type IgA and IgG and IgA antitransglutaminase related with celiac disease (CD). METHOD OF STUDY ANA, ASMA, AMA, anti-LKM, antibodies to GPC and ANCA were determined by indirect immunofluorescence (IFI) and anticardiolipin, antigliadina and antitransglutaminase antibodies were measured by enzyme-linked immunosorbent assays (ELISA). RESULTS There was no significant difference between controls and patients with ANA, ASMA, AMA, LKM, ANCA and GPC. The prevalence of anticardiolipin antibodies in RPL was significantly higher than controls (P < 0,01) and the prevalence of positive antibodies for antigliadina type IgA and IgG and IgA antitransglutaminase in RPL was significantly higher than controls (P < 0.04). CONCLUSION We show that Caucasian Argentine women with RPL showed significantly higher incidence of anticardiolipin antibodies than normal controls and finally we recommended the screening of IgA and IgG antigliadina and IgA antitransglutaminase antibodies in pregnancy, because of the high prevalence of subclinical CD in RPL and the chance of reversibility through consumption of a gluten free diet.

Abstract
Implantation in humans is a complex, closely regulated, highly selective and relatively poorly understood process. Humans have the highest rate of miscarriage in mammals and various pharmacological manipulations have been used to minimize pregnancy losses in both spontaneous pregnancies and pregnancies resulting from assisted reproduction technology. The widespread application of protocols using numerous drugs in assisted reproduction treatment has led to an increasing number of pregnancies exposed to these drugs. The vast majority of these protocols have been based on data from a few observational and often retrospective clinical studies. This paper reviews the recent literature on drug interventions in early pregnancy after assisted reproduction treatment. It is concluded that there are still numerous issues about the safety of most drugs for both the women and their fetus. In many cases, the benefits are theoretical and the possible long-term side-effects are untested. There is an urgent need for more epidemiological studies and randomized controlled trials to explore the use, efficacy and side-effects of both old and new drugs in early pregnancy after assisted reproduction treatment.

Abstract
Antiphospholipid antibodies (aPL) are immunoglobulins of IgG, IgM and IgA isotypes that target phospholipid (PL) and/or PL-binding plasma proteins. Detection of aPL in the laboratory is done currently by both immunoassays and functional coagulation tests. Convention defines aPL specificity in immunoassays according to the particular PL substrate present, for example aPS represents antiphosphatidylserine antibodies. This may be technically incorrect inasmuch as a particular PL may be responsible for binding and highly concentrating a specific plasma protein, the latter then becomes the target for the aPL. The binding of beta(2)GP-I (apolipoprotein H) to the negatively charged PL, cardiolipin (CL) provides a good example of this circumstance. In contrast, aPL which specifically prolong coagulation times in in vitro are called lupus anticoagulants (LA). The precise PL target(s) of the aPL responsible for LA activities are unknown and often debated. The persistent finding of aPL in patients in association with abnormal blood clotting and a myriad of neurological, obstetrical and rheumatic disorders often compounded by autoimmune diseases has led to an established clinical diagnosis termed antiphospholipid syndrome (APS). The common denominator for these APS patients is the presence of circulating aPL on two or more occasions and the observation of events attributable to abnormal or accelerated blood clotting somewhere in vivo. The purpose of this review is to collect, collate, and consolidate information concerning aPL.

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
Reports of anti-phosphatidylethanolamine antibodies (aPE) with similar or identical pathogenic associations as those described for anticardiolipin (aCL) and anti-phosphatidylserine (aPS) are found in the literature. In some instances, aPE is the sole antiphospholipid antibody (aPL) observed. Lupus anticoagulant antibodies (LA) appear to represent a subset of aPE as hexagonal phase PE can specifically inhibit the LA ability to prolong clotting times. As documented for aPL to the negatively charged phospholipids (PL), plasma proteins have been implicated for a positive aPE signal in the ELISA. Other aPE appear independent of known PE-binding plasma proteins. Among the described PE-binding proteins are high and low molecular weight kininogens (HMWK and LMWK) and the HMWK-binding proteins, factor XI and prekallikrein. Recently prothrombin has been added to this list. The reports of aPE published since 1986 are reviewed and discussed in this presentation.

Abstract
OBJECTIVE The purpose of this study was to investigate the frequency of B-1 cells in the peritoneal cavity and peripheral blood of patients with endometriosis. MATERIALS AND METHODS We examined 31 patients with endometriosis and 14 normal nonpregnant women. Peripheral blood cells and peritoneal exudate cells (PECs) were stained with FITC or PE-labeled anti-CD5/CD19 monoclonal antibodies. Immunofluorescence analysis was performed using a flow cytometer. The significance of differences between the patient and control groups was determined by the non-parametric Mann-Whitney test. RESULTS There was no significant difference in the percentages of B-1 cells in the peripheral blood of women with and without endometriosis (median, 22.7%; range, 4.7-92.3% vs median, 20.05%; range, 11.1-12.6%, respectively). Endometriosis patients with antinuclear antibodies (ANAs) demonstrated significantly elevated B-1 cells compared to both endometriosis patients without ANAs and normal controls (p < 0.005 and p < 0.05, respectively). Endometriosis patients demonstrated significantly higher B-1 cell populations (B-1 cells/total B-cell ratio) in PECs than did non-endometriosis patients (p < 0.05). CONCLUSIONS The peripheral B-1-cell population in patients with endometriosis is related to ANA production. B-1 cells might play important roles in the development of endometriosis through autoantibody production.

Abstract
PROBLEM Several immunological factors have been associated with diagnostic subpopulations of reproductive failure. It is important to determine a trend of immunological abnormalities among these subpopulations. The purpose of this study is to assist in the selection of treatment for patients suspected of having specific diagnoses of reproductive failure. METHOD OF STUDY Blood samples from 591 patients were evaluated for the presence of antiphospholipid (APA), antinuclear (ANA), and antithyroid (ATA) antibodies, as well as for lupus anticoagulant (LA), embryotoxic factors (ETF), and elevated levels of natural killer (NK) (CD56+) cells, and all tests were performed as a panel. The patients were grouped into the following diagnostic categories: recurrent pregnancy loss (n = 302), IVF/ET failure (IVFf, n = 122), unexplained infertility (n = 97), ovarian dysfunction (n = 47), and endometriosis (n = 23). The thresholds for positivity and the prevalence of the tested factors among normal healthy populations have been established by testing 100 or more healthy male and female individuals with each one of the tests used (general population control). All tests as panel were performed on 20 normal fertile female individuals as controls (fertile female controls). RESULTS Of all patients with reproductive failure, 75.6% had at least one abnormal test. The most frequent abnormal result was found to be the elevation of NK (CD56+) cells (37%), followed by ANA (34%), APA (24%), ATA (19%), and ETF (11%). Of the recurrent pregnancy loss patients, 74.2% had at least one positive abnormal result from all of the tests performed: overall, 70% of women with IVF failure had at least one abnormal test; of patients diagnosed with unexplained infertility, approximately 81% had at least one abnormal result; 74.4% of the patients with ovarian dysfunction and 52% of the patients with endometriosis had at least one abnormal result. From normal fertile controls, 10% showed at least one abnormal test result. CONCLUSION APA, ANA, ATA, ETF, and elevated NK (CD56 ) cells are significantly more prevalent among women experiencing reproductive failure than among the control group and normal healthy individuals.

Abstract
BACKGROUND Biopsy specimens of transplanted kidneys that fail to function reveal cellular infiltrates, infarcts, and thrombi. Because antibodies to phospholipids (aPA) and/or phospholipid-binding proteins have been associated with thrombosis, we asked whether aPA are a risk factor for early allograft failure. METHODS Final crossmatch sera from 56 patients with primary nonfunctioning renal allografts were tested for aPA. Serum from the next consecutive patient to undergo transplantation served as transplantation controls. Both groups were compared with aPA values obtained from testing 252 control individuals. The ELISA was designed to detect IgG, IgM, and IgA antibodies to phosphatidylserine, cardiolipin, and phosphatidylethanolamine. RESULTS Patients were evaluated based upon the aPA ELISA findings. aPA were present in 57% of the patients with early nonfunction renal allografts and 35% of the patients with functioning grafts (P=0.0234). aPA in previously hemodialyzed patients did not predict allograft failure or success (P=0.3766). In contrast, all nonhemodialysis patients who had aPA at the time of transplantation experienced early allograft failure (P=0.0022). CONCLUSIONS These data show that aPA are an important risk factor for early renal allograft failure. Furthermore, aPA-positive patients who have no history of hemodialysis are at the greatest risk. Pretransplantation aPA screening of renal transplant candidates forewarns of early graft failure and indicates which patients may benefit from anticoagulant therapy.

Abstract
PROBLEM The aim of this study was to contribute to the study of the pathogenesis and the treatment of recurrent spontaneous abortion (RSA) associated with immune alterations. METHOD OF STUDY This is a prospective clinical trial with 11 patients with RSA associated with allo- and autoimmunity not receiving lymphocyte immunizations but only heparin and aspirin preconceptionally and through pregnancy. A concurrent group of 8 patients receiving a complete therapy (lymphocyte immunizations, heparin, and aspirin) but not receiving heparin and aspirin preconceptionally is also included in this report. RESULTS The rate of pregnancy success in these patients was 90.9% (10/11), and the rate of success of the concurrent group was 75.0% (6/8). CONCLUSIONS The results are in agreement with the working hypothesis regarding the possible final common mechanism in the pathogenesis of abortion associated with allo- and autoimmunity. The "single" therapy with heparin and aspirin was effective, less costly, and logistically simpler to provide than a complete therapy including lymphocyte immunizations.

Abstract
Antiphospholipid antibodies were first linked to pregnancy loss more than 20 years ago, and the condition known as antiphospholipid syndrome is perhaps the most convincing 'immunologic' disturbance other than anti-erythrocyte and anti-platelet alloimmunization disorders. Specific criteria for the antiphospholipid syndrome have been delineated, the anticardiolipin assay has been standardized, and authorities agree on laboratory criteria defining lupus anticoagulant. Nonetheless, considerable confusion exists regarding antiphospholipid syndrome and related reproductive problems. The state of affairs primarily derives from two problems: the first is the premature introduction of non-standardized antiphospholipid assays into clinical use without rigorous standardization and prior to convincing proof of clinical utility. As a result, well-intending, but less well-versed clinicians sometimes make the diagnosis of antiphospholipid syndrome in women who are negative for lupus anticoagulant and anticardiolipin antibodies. This is especially confusing in the face of of growing evidence that the relevant in vivo antiphospholipid antigen is formed by a complex between beta 2-glycoprotein 1 and phospholipids. A second major problem is that of unwarranted discrepancies in the clinical and laboratory features of patients considered to have a diagnosis of antiphospholipid syndrome. This problem is most apparent in the case selection for pregnancy-loss treatment series and trials. Many series have included women with predominantly pre-embryonic and embryonic pregnancy losses, while others included a large majority of patients with one or more second or third trimester pregnancy losses. Some treatment trials purposefully excluded patients with a history of thrombosis or systemic lupus erythematosus, features found in nearly 50% of patients in other series. Though most authorities require the presence of either lupus anticoagulant or medium-to-high titer IgG anticardiolipin antibodies to make a diagnosis of antiphospholipid syndrome, in some series no more than half of the study patients had lupus anticoagulant and as many as 20% had only IgM anticardiolipin antibodies. It is very unlikely that patients with such disparate clinical and laboratory findings have the same autoimmune syndrome, and a stated or implicit diagnosis of antiphospholipid syndrome in such a wide variety of women is scientifically unsound and clinically dangerous. The relationship between antiphospholipid antibodies and poor reproductive outcomes must be approached through rigorous scientific study and appropriate treatments established by well-designed clinical trials.

Abstract
To be sure, antiphospholipid antibody syndrome is a protean disease with many manifestations, some of which are exacerbated during pregnancy, and some of which even lead to its initial diagnosis during pregnancy. Although the best treatment during pregnancy is uncertain at this point, and some of the treatments are even experimental, there does seem to be a benefit in at least identifying and probably treating those with risk factors. If treatment is not instituted with heparin, aspirin, or other medical management, at least monitoring for the known superimposed disease states, such as intrauterine growth retardation, preeclampsia, and fetal loss, should be judicious, with close antenatal surveillance.

Abstract
OBJECTIVE This study was performed to determine whether primary habitual aborters have an autoimmunological tendency and whether immunotherapy with leukocytes induces autoantibodies in their sera. METHODS We measured the levels of antiphospholipid antibodies (APAs) and antinuclear antibodies (ANAs) in the sera of 65 primary habitual aborters. Among them, 8 primary habitual aborters received immunotherapy with their respective husband's leukocytes; these 8 patients were followed up for autoantibodies in their sera before immunotherapy, at the time of pregnancy permission, during the first trimester of pregnancy, at delivery, and postpartum. RESULTS Sixty-nine percent of the 65 primary habitual aborters were positive for IgG or IgM antibodies to at least 1 of 6 phospholipids, and 29% of them were positive for ANAs. Although the pregnancy outcomes of the 8 primary habitual aborters after immunotherapy were good, their APAs and ANAs converted to positive after the immunotherapy. CONCLUSION Immunotherapy with leukocytes should be performed after checking and confirming the absence of autoantibodies in the sera of a habitual aborter.

Abstract
In summary (1) Nonpregnant women with RSAs of unknown etiology have higher levels of CD56+ lymphocytes when compared to normal controls; (2) The levels of CD19+, CD56+, and CD56+/CD16+ PBL of pregnant women with RSA are significantly higher than those of multiparous pregnant normal controls; (3) Women with autoantibodies to phospholipids have significantly higher levels of elevated CD56+ and CD56+/CD16+ lymphocytes when compared to women without antiphospholipid antibodies; (4) Women with autoantibodies to nuclear components demonstrate higher numbers of CD19+/CD5+ cells compared to women without autoantibodies to nuclear components; (5) Idiopathic infertile women with multiple prior IVF failures demonstrate significantly higher levels of CD56+ pBL than normal fertile controls and the conception rate is much higher in those with CD56+ levels less than 12%; (6) Elevations of CD56+ lymphocytes to over 18% during a pregnancy is a good prognostic indicator of impending pregnancy loss. We have not seen a liveborn infant in women with levels of 18% or higher without IVIg therapy; and (7) Infertile and RSA women who fail alloimmune and autoimmune therapy have significant alterations in cellular and humoral immunity involving NK cells and CD19+/CD5+ B cells.

Abstract
PROBLEM We investigated the hypothesis that elevated peripheral blood natural killer cells (NK) are decreased by immunoglobulin G infusion (IVIg) therapy in women with recurrent spontaneous abortions (RSA) and elevated NK cells. METHODS Seventy-three women with RSA and elevated NK cells received IVIg therapy (400 mg/Kg/day for 3 days ever 4 wks) and anticoagulation treatment. Peripheral blood immunophenotype assay by flow cytometry was done prospectively prior to and 7 days after first IVIg therapy, every 2 wks until 20 wks gestation and then monthly. Controls were 95 women with RSA and normal NK cells who received anticoagulation treatment. RESULTS (1) 86.3% of women with elevated NK cells who received the IVIg and anticoagulation therapy had a successful pregnancy outcome; (2) Peripheral blood CD56+ NK cells and CD56+/16+ NK cells were significantly suppressed 7 days post IVIg infusion (P < 0.0005); (3) Pre-IVIg infusion levels of other lymphocyte subsets were not different as compared with those of 7 days post-IVIg therapy; (4) Women who delivered a liveborn infant with IVIg therapy demonstrated downregulation of peripheral blood NK cells (CD56+, CD56+/16+) during early pregnancy when compared to women who miscarried the index pregnancy (P < 0.05); (5) Women with normal NK cells who miscarried while on anticoagulation therapy demonstrated significantly elevated CD56+ NK cells during early pregnancy as compared with that of women who delivered a liveborn infant (P < 0.05); (6) CD19+ B cells were significantly downregulated during pregnancy in women with anticoagulation and IVIg therapy when compared to women with anticoagulation therapy (P < 0.05). CONCLUSION Downregulation of NK cells in women with RSA is associated with a favorable pregnancy outcome. Peripheral blood NK cells (CD56+, CD56+/16+) are effectively suppressed after IVIg therapy. Women with RSA and high NK cells benefit from IVIg therapy and experience suppression of CD56+ and CD56+/16+ NK cells.

Abstract
The objective of this paper is to determine whether age has any impact on conception rate, pregnancy outcome, or autoimmune status in women with recurrent spontaneous abortions (RSA) and infertility of immune etiology. One hundred twenty-four women with 3 or more RSA and 36 women with unexplained infertility were prospectively studied. Maternal antipaternal lymphocyte antibodies and autoantibodies to phospholipids and nuclear antigens were tested. All achieved an adequate alloimmune recognition after lymphocyte immunization and followed for 1 year with optimal preconception autoimmune treatment. Conception rate and pregnancy outcome were prospectively studied. 1) 10.1% of women with RSA and 30.6% of women with infertility failed to achieve a pregnancy after 1 year of trial (P = 0.0084); 2) in women with RSA, the number of previous fetal death after 28 weeks of gestation was significantly higher in women who failed to achieve a pregnancy within 1 year when compared to women who became pregnant (P = 0.0296). Conception rate was not different with advancing age; 3) women with infertility demonstrated significantly higher incidence of anti-phosphatidylethanolamine antibody when compared to women with RSA (P = 0.052); 4) in women with infertility, those who failed to achieve a pregnancy were significantly older (P = 0.0012) and demonstrated a higher incidence of autoantibodies to phosphatidic acid than women with infertility who became pregnant (P = 0.0339); 5) the subsequent spontaneous abortion rate while on optimal immune therapy was the same in the women with RSA (39.3%) and women with infertility (32%). Spontaneous abortion rate of women with RSA or infertility was not different among four age groups; 6) the presence of anticardiolipin antibody (P = 0.0055) and higher gravidity (P = 0.0354) correlated significantly with pregnancy failure in women with a history of infertility. The prevalence of auto-antibodies to phospholipids and nuclear components was not different among four age groups in women with RSA or infertility. Age does not affect pregnancy outcome or conception rate in women with RSA. In women with infertility of immune etiology, conception rate was significantly reduced over age 40 although pregnancy outcome was no different with advanced age.

Abstract
PROBLEM If damage to the trophoblast mediated through autoimmune mechanisms is responsible for recurrent spontaneous abortions (RSA), maternal class II HLA antigens might be expected to be involved. We wanted to evaluate the impact of these antigens on pregnancy outcome in RSA women and their relatives. METHOD HLA-DR and -DQ typing using RFLP and PCR-SSP methods was carried out in 234 Danish women with unexplained RSA and 360 controls. The HLA-DR types were correlated to outcome of the next pregnancy in 94 patients. Sisters, brothers, and wives of brothers of 146 consecutive patients were HLA typed and their pregnancy outcomes were correlated to the HLA-DR types. RESULTS HLA-DR1/Br and -DR3 were each significantly increased in women with at least four previous pregnancy losses (both P-values < 0.05 after correction for multiple comparisons). In the prospective study, 62% of the HLA-DR1/Br and/or -DR3 positive patients miscarried the next pregnancy compared with only 29% of those negative for both allogenotypes (P = 0.025). The family studies indicated that female relatives of RSA patients had a greater risk (odds ratio = 5.0, 95% CI = 2.0-11.0) of pregnancy losses when positive for HLA-DR1/Br and/or -DR3 than those negative for the allogenotypes. CONCLUSIONS Maternal HLA-DR allogenotypes DR1/Br and -DR3 or closely linked genes seem to predispose to pregnancy losses in RSA patients and their first degree relatives.

Abstract
OBJECTIVE To determine the occurrence of antibodies to oxidized low-density lipoprotein (LDL) in women with a history of habitual abortion before and during pregnancy. DESIGN Immunoglobulin G class antibodies to malondialdehyde modified LDL were determined by a solid-phase ELISA in 42 habitual aborters before pregnancy, in 39 patients during pregnancy, and in 23 comparable nonpregnant and 22 pregnant control women without a history of abortion. In addition, we assessed the presence of anticardiolipin antibodies by ELISA in the same sera. SETTING Departments I and II of Obstetrics and Gynecology, University Central Hospital of Helsinki, Helsinki, Finland. RESULTS Early pregnancy was accompanied by a decrease in the median levels of antibodies to oxidized LDL both in habitual aborters and in the control series. Only one patient exhibited a raised level of antibodies to oxidized LDL before pregnancy but, during pregnancy, nine patients (23%) had elevated levels of antibodies to oxidized LDL, similar to women with a favorable outcome of pregnancy (6/27, 22%) and in women whose current pregnancy also ended in abortion (3/12, 25%). Cardiolipin binding antibodies were detected in three habitual aborters before pregnancy (7%) and in nine women during pregnancy (23%), with a tendency to be more frequent in patients with miscarrying pregnancies than in those with continuing pregnancies (4/12, 33% and 5/27, 19%). Antibodies to oxidized LDL and cardiolipin were simultaneously present in three habitual aborters with continuing pregnancies. CONCLUSIONS Increased levels of antibodies to oxidized LDL and cardiolipin may be associated with habitual abortion.

Abstract
PROBLEM To analyze immunophenotypic profiles of peripheral blood and humoral autoimmune responses in women with a history of recurrent spontaneous abortions (RSA). METHOD Peripheral blood lymphocyte subsets by flow cytometry and autoantibodies to phospholipids and nuclear components by ELISA were measured in nonpregnant and pregnant women with RSA of unknown etiology. Thirty-five pregnant and eighty-one nonpregnant women with RSA were studied. Seventeen nonpregnant and twenty-two pregnant normal controls were included. RESULTS Natural killer (NK) cells (CD56+) were significantly elevated in nonpregnant women with RSA as compared with nonpregnant controls. Pregnant women with RSA demonstrated significantly increased NK (CD56+, CD56+/CD16+) and B cells (CD19+) as compared with pregnant controls. Women who miscarried the index pregnancy demonstrated significantly lower CD3+ cells in comparison with normal controls. Women with RSA and antiphospholipid antibodies showed significantly elevated NK cells when compared with women without antiphospholipid antibodies. Women with autoantibodies to nuclear components demonstrated significantly elevated CD19+/CD5+ cells when compared to women without autoantibodies to nuclear components. CONCLUSIONS Women with RSA demonstrate an abnormal cellular immune response by increasing peripheral natural killer cells and B cells as compared with normal controls.

Abstract
The HLA allogenotypes DR1/Br, DR3 and DR10 (entitled risk HLA markers) have been reported as being genetic markers for the predisposition to experience unexplained recurrent fetal losses. The aim of the study was to determine whether the putative risk HLA markers might also be markers for the risk of pregnancy loss in sisters and wives of brothers of women with unexplained recurrent fetal losses. Information concerning pregnancy outcomes among the relatives of 146 consecutive women with unexplained recurrent fetal losses was collected. Ninety-five of the full sisters, 69 of the full brothers and 50 of the wives of the brothers were HLA typed. Sisters who had experienced at least one previous pregnancy loss (affected women) shared more HLA haplotypes with the proband than unaffected sisters, when the proband was positive for the risk markers (P = 0.02). More affected than unaffected sisters and brothers' wives were positive for the risk markers (P < 0.005 and P < 0.03; respectively). The lowest estimate of the odds ratio for experiencing pregnancy loss among sisters and brothers' wives who were positive compared with those negative for the risk markers was 3.5 (95% credible interval = 1.9-5.8). It is concluded that maternal DR1/Br, DR3 and DR10 allogenotypes seem to be genetic markers for the risk of pregnancy loss among relatives of women with unexplained recurrent fetal losses. The pattern of inheritance suggests a polygenic mode of inheritance with alleles linked to the risk HLA markers interacting with non-HLA linked genes expressed on the fetus or the trophoblast.

Abstract
Monkeys with excellent reproductive histories were immunized with the laminin peptides YIGSR, RGD, IKVAV, and YD, a control sequence with no known biological function. Sera from the YIGSR-immunized monkey became toxic, causing neural tube defects in whole rat embryo cultures, and this monkey experienced fetal loss after immunization. Sera from the RGD-immunized monkey also became embryotoxic in culture after immunization, but this monkey appeared to become infertile as she failed to initiate a pregnancy for at least 2 years after immunization. In contrast, embryos cultured on sera from the IKVAV- or YD-immunized monkeys were predominantly normal and both monkeys completed successful pregnancies. Antibody levels to the respective peptides or to laminin were not predictive of embryotoxicity, but antibody binding to homogenized yolk sacs as well as to yolk sacs of cultured embryos was associated with sera embryotoxicity and reproductive outcomes in vivo. These observations suggested that the laminin sequences YIGSR and RGD may play a role in immune-mediated reproductive failure by reacting directly with embryonic tissue and could provide a basis for identifying individuals at risk for both spontaneous abortion and infertility.

Abstract
We have investigated clinical effectiveness of intravenous immunoglobulin G infusion (IVIg) on antiphospholipid antibody titers in five women with evidence of antiphospholipid antibody-associated recurrent spontaneous abortions and one with antinuclear antibody who became refractory to conventional autoimmune treatment during pregnancy and experienced pregnancy complications. Three women developed intrauterine growth retardation and three had complicated twin pregnancies with rising autoantibody titers. Antiphospholipid antibody and antinuclear antibody titers were tested pre and 2 weeks after each IVIg infusion. We report that: (i) IgG antiphospholipid antibody titers were significantly suppressed after each IVIg infusion (P < 0.05); (ii) IgM antiphospholipid antibody titers were also significantly suppressed after each IVIg infusion (P < 0.0001); (iii) decreased titers of autoantibodies paralleled increased levels of maternal IgG which lasted for at least 30 days; the autoantibodies showed a definite rise again prior to the next infusion; (iv) antinuclear antibody titers were effectively suppressed; and (v) rising autoantibody titers combined clinical manifestation of intrauterine growth retardation and women with complicated twin pregnancies. We conclude that IVIg infusion effectively suppresses IgM and IgG autoantibodies to phospholipids and antinuclear antibody in autoimmune women with a history of recurrent spontaneous abortions and refractory to conventional anticoagulation or immunosuppressive treatment.

Abstract
PROBLEM The role of ACA in unexplained RSA is controversial. In the present study, diagnostic and prognostic aspects were investigated. METHOD One hundred five nonpregnant patients with primary, 29 with secondary RSA, and 209 controls were investigated for IgG-ACA. Follow-up studies were done during pregnancy in 76 individuals. IgM-ACA were tested in a subset of patients. RESULTS Elevated ACA levels were significantly more frequent in both patient groups (26 and 24%) than in controls (16%). However, there was no correlation of ACA with various parameters including pregnancy outcome. In ACA-positive patients with successful pregnancy a significant decrease of ACA values during pregnancy was observed, while ACA remained high in aborting patients. IgG- and IgM-ACA correlated well. CONCLUSIONS Although the data from nonpregnant RSA patients does not allow diagnostic or prognostic conclusions to be drawn, sequential testing of ACA-positive individuals provides the possibility to foresee pregnancy outcome.

Abstract
This prospective study is an attempt to address the issues of whether or not antiphospholipid antibodies (aPL) constitute a significant risk factor for pregnancy in individuals with systemic lupus erythematosus (SLE) and whether or not combination therapy of high-dose prednisolone (PSL) and low-dose acetylsalicylic acid (ASA) offers efficient control. Antibodies against six phospholipids were measured in sera of patients with stable SLE who had no severe complications before pregnancy, and were followed up during subsequent pregnancies. Four of 12 patients with SLE demonstrated aPL-positivity. Six of 8 patients without aPL had appropriate-for-date (AFD) live babies, the remaining two suffering intrauterine fetal death (IUFD) in the first trimester, one having a chromosome abnormality. Two aPL-positive patients treated only with 5-15 mg/day PSL during pregnancy ended in IUFD in the second trimester. In contrast, the other two patients treated with high-dose PSL and low-dose ASA each had AFD live babies at 38 weeks gestation. The results suggest that APL is a crucial risk factor in pregnancy with stable SLE. Combination therapy of high-dose PSL and low-dose ASA may enable aPL-positive patients with SLE to have AFD live babies.

Abstract
Autoantibodies to negatively charged phospholipids have been reported to be associated with thrombotic events, thrombocytopenia and adverse pregnancy outcome, such as intrauterine growth retardation and recurrent spontaneous abortions (RSAs). In this study, autoantibodies to 6 phospholipid antigens and antinuclear antibody (ANA) were tested in Colombian women with a history of RSAs. Sixty-eight non-pregnant and 25 pregnant women with a history of RSAs comprised the study group. Twenty-five non-pregnant normal healthy women and thirty-one normal pregnant women served as controls. The non-pregnant women with RSAs showed a higher incidence of autoantibodies to cardiolipin (23% positive) as compared with non-pregnant normal controls (0% positive; P < 0.005). The incidence of autoantibodies to cardiolipin (28%; P < 0.005), phosphatidylethanolamine (16%; P < 0.005), phosphatidylserine (16%; P < 0.05), phosphatidylglycerol (16%; P < 0.05), phosphatidic acid (16%; P < 0.01) and phosphatidylinositol (20%; P < 0.01), in the pregnant women with RSAs was significantly higher than that of normal pregnant controls. There was no difference in the incidence of ANA in either group. In conclusion, women with a history of RSAs have a higher incidence of autoantibodies to phospholipids when compared to pregnant and non-pregnant normal controls. Autoimmune serological work-up is indicated during pregnancy in women with a history of RSAs.
