Zhang ZM, Zhang N, Wang XF. Prognostic model on pregnancy outcomes for women with recurrent spontaneous abortions treated with cyclosporin A: A single-institution experience. Clinics (Sao Paulo) 2024; 79:100349. [PMID: 38613917 PMCID: PMC11033085 DOI: 10.1016/j.clinsp.2024.100349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 02/20/2024] [Accepted: 03/12/2024] [Indexed: 04/15/2024] Open
Abstract
BACKGROUND This study aimed to identify prognostic factors for pregnancy outcomes and construct a prognostic model for pregnancy outcomes in women with Recurrent Spontaneous Abortions (RSA) treated with cyclosporin A. METHODS A total of 154 RSA patients treated with cyclosporin A between October 2016 and October 2018 were retrospectively recruited. Multivariate logistic regression was applied to identify the prognostic factors for pregnancy success in RSA women treated with cyclosporin A. The Receiver Operating Characteristic (ROC) curve was applied to construct prognostic value, and the prognostic performance was assessed using area under the ROC. RESULTS After adjusting potential confounding factors, the authors noted increased age (OR = 0.771; 95 % CI 0.693‒0.858; p < 0.001) and positive antinuclear antibodies (OR = 0.204; 95 % CI 0.079‒0.526; p = 0.001) were associated with a reduced incidence of pregnancy success, while positive anti-β2 glycoprotein-I-antibody (OR = 21.941; 95 % CI 1.176‒409.281; p = 0.039) was associated with an increased incidence of pregnancy success after treated with cyclosporin A. The AUC of combining these variables for predicting pregnancy failure was 0.809 (95 % CI 0.735‒0.880). CONCLUSIONS This study systematically identified the prognostic factors for pregnancy success in women treated with cyclosporin A, and the constructed prognostic model based on these factors with relatively higher prognostic value. Further large-scale prospective studies should be performed to validate the prognostic value of the constructed model.

Association between antinuclear antibody positivity and chemical exposure among pregnant Japanese women: A cross-sectional study based on the Japan environment and Children's study. Int J Hyg Environ Health 2023; 248:114094. [PMID: 36610096 DOI: 10.1016/j.ijheh.2022.114094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2022] [Revised: 10/21/2022] [Accepted: 12/01/2022] [Indexed: 01/06/2023]
Abstract
Antinuclear antibodies (ANAs) are detected in healthy individuals, they are more prevalent in women than in men. Pregnant women are immunologically unique, but epidemiological data on ANA positivity in them remain limited. The exposure received from the mother during the fetal period impacts the future health of the fetus and has thus received increased attention in recent years. Thus, we investigated the association between ANA positivity and chemical exposure among pregnant Japanese women, registered in the Japan Environment and Children's Study (JECS). ANA titers were assessed by indirect immunofluorescence with HEp-2 cells at a cutoff dilution of 1:40. Sociodemographic and other data were obtained in the JECS from a self-administered questionnaire. We analyzed 1,235 Japanese women in their first trimester of pregnancy. The ANA prevalence was 17.2%. Among ANA-positive women, a speckled pattern was the most common (95.3%), followed by a homogeneous pattern (72.3%). Exposure to chemicals more than once a week significantly increased the probability of ANA positivity (kerosene, petroleum, benzene, or gasoline: adjusted odds ratio [AOR], 2.11; 95% confidence interval [95% CI], 1.03-4.34; chlorine bleach or germicide: AOR, 1.97; 95% CI, 1.10-3.54; organic solvents: AOR, 5.34; 95% CI, 1.40-20.36; and photocopying machines or laser printers: AOR, 1.73; 95% CI, 1.17-2.54). ANA positivity was associated with exposure to several chemicals in Japanese women. Our exploratory results suggested that ANAs as potential markers of chemical exposure warrant further research.

Abstract
Miscarriage in the first and second trimesters of pregnancy is very common, and coagulopathy can be a contributing factor. Protein C and S deficiency are rare, inherited disorders that can increase the risk of thrombophilia. Women with these deficiencies have a higher risk of developing blood clots in the placenta, which can lead to placental insufficiency and, ultimately, to a miscarriage. We aimed to compare the levels of protein C and protein S in pregnant females with recurrent first and second-trimester pregnancy loss and normal pregnant females. We performed a detailed history, examination, and various lab tests on a cohort of 40 females with a history of recurrent first and second-trimester abortions visiting an outpatient clinic at a multi-specialty hospital in Kashmir, India. All the findings were compared with 40 women with normal pregnancies. 10% of the participants had low protein C and S levels (P=0.277), out of whom 75% (p<0.001) had intrauterine growth retardation (IUGR) on ultrasound with 67% (p<0.001) having reduced doppler flow in the umbilical artery. 0.05% of participants had isolated protein S deficiency with no concomitant IUGR seen. Patients with protein C and S deficiencies were treated with heparin and progesterone and followed up for pregnancy outcomes. Screening for protein C and S deficiency is mandatory in all cases of recurrent pregnancy loss. Treatment with low molecular weight heparin and progesterone should be initiated to ensure good fetal outcomes and prevent post-partum/postoperative catastrophic venous thromboembolism events.

Abstract
OBJECTIVE To explore the risk factors for adverse pregnancy outcomes (APOs) in women with rheumatoid arthritis (RA) and the influence on their offspring health. METHODS Pregnant women with RA (n = 67) who were hospitalized in the Department of Obstetrics, Peking University People's Hospital between January 2007 and September 2021 were included in this study. Participants were evaluated at least once in each trimester and postpartum. Fetal outcomes and RA disease activity were extracted from medical records, and the offspring of enrolled patients were followed up. Associations between RA disease activity, medication use, and pregnancy outcomes were analyzed. RESULTS The incidence of APOs in our cohort was 43.3%. Postpartum hemorrhage (20.9%) was the commonest complication, followed by premature delivery (11.9%). Previous miscarriages [odds ratio (OR): 1.869, 95% confidence interval (CI): 1.053-3.318, P = 0.033] and antinuclear antibody (ANA) positivity (OR:3.168, 95% CI: 1.068-9.768, P = 0.045) were risk factors for APOs. Compared to patients with APOs, the remission rate of disease activity during pregnancy was higher in patients without APOs (P = 0.027). There were no significant differences between patients with and without APOs with respect to daily and cumulative doses of prednisone (P > 0.05). The average age of the offspring was 4.9 years (range 0.3-14 years). Long-term follow-up showed no significant differences in offspring health between the two groups (P > 0.05). CONCLUSION Previous miscarriages and ANA positivity are independent risk factors for APOs in RA patients, while adverse pregnancy outcomes and low-dose prednisone have no effect on offspring health. Key points • Previous miscarriages and ANA positivity are risk factors for APOs in RA patients. • Adverse pregnancy outcomes and low-dose prednisone during pregnancy have no effect on offspring health.

Abstract
ObjectivePatients with antiphospholipid syndrome (APS) have immune cell abnormalities that remain poorly understood. This study compared primary APS (PAPS) and secondary APS (SAPS) patients with healthy controls with respect to peripheral blood lymphocytes, CD4+T cell subsets, and cytokine levels. The correlation between antiphospholipid antibody titres and T helper 17 (Th17) and T regulatory (Treg) cell subsets was also analyzed, together with the correlations between cytokine profiles and the clinical characteristics of APS patients.MethodsThe retrospective study population consisted of 67 APS patients (12 with PAPS, 55 with SAPS) and 40 healthy controls. Absolute numbers of peripheral blood lymphocyte subsets and CD4+ T cell subsets were detected by flow cytometry, and serum cytokine levels by flow cytometry bead array.ResultsPatients with SAPS had lower absolute values of T, B and CD4+T cells than the healthy control group, while only natural killer (NK) cell levels were decreased in patients with PAPS. Absolute numbers of T, B, NK, and CD4+T cells were significantly higher in the PAPS than SAPS group. The trends in CD4+T cell subsets were the same in PAPS and SAPS patients as in healthy controls, with increased Th1, decreased Th2, and decreased Treg levels, and thus an increased Th17/Treg ratio. Th2, Th17, and Treg cell counts were higher in the PAPS than SAPS group. Cytokine analysis showed that only IL-10 levels differed between the two APS groups. However, the levels of all of the studied cytokines were higher in APS patients than healthy controls, and correlated with the clinical characteristics of the patients. In the PAPS group, the titres of two autoantibodies correlated positively with the Th17/Treg ratio and negatively with the levels of D-dimer and Treg subsets.ConclusionsOur study clearly showed that APS patients have immune disturbances, the most prominent of which is an increase in the Th17/Treg ratio, due to a decrease in the number of Treg cells. These abnormalities may be involved in the occurrence and progression of APS. An additional finding was a higher level of peripheral blood lymphocytes in PAPS than SAPS patients, which may be related to the immunosuppressive treatment of SAPS patients.

Abstract
OBJECTIVE To explore the effect of anti-nuclear antibodies (ANAs) on the outcome of in vitro fertilization-embryo transplantation (IVF-ET) and to study the effect of ANAs in follicular fluid (FF) on embryonic development. METHODS The expression of ANAs in FF of patients treated with IVF-ET and healthy group. The patients were divided into ANAs-positive group and ANA-negative group. The age, duration of infertility, body mass index (BMI), basic follicle stimulating hormone (bFSH), anti-Mullerian hormone (AMH), number of retrieved oocytes, portion of metaphase II oocytes (MII), number of embryos in the cleavage stage, bipronuclear (2PN), number of embryos, number of high-quality embryos and the outcome of IVF-ET were compared between the two groups. In vitro, HTR8/SVneo trophoblast cells were cultivated and divided into ANAs-negative group (control group) and ANAs-positive group (ANAs-positive FF was added to cytotrophoblasts). The ANAs titer in the serum and FF of patients who treated with IVF-ET was detected using ELSIA method. CCK-8 assay and flow cytometry (at 24 h and at 48 h) were used to detect the cell proliferation and apoptosis frequency of the two groups, respectively. RESULTS Among those who underwent IVF-ET treatment, the number of retrieved oocytes, the number of fertilization and the portion of MII oocytes in the FF-positive group were significantly lower than those in the FF-negative group. Furthermore, the implantation rate and the clinical pregnancy rate were decreased, and early miscarriage rate was increased in the FF-positive patients than those in the FF-negative patients. In vitro, the cytotrophoblasts proliferation activity in the ANAs group was significantly lower than that in the control group. Moreover, the cytotrophoblasts apoptosis rate in the ANAs group was significantly higher than that in the control group. CONCLUSIONS Our data suggested that ANAs in FF might become an obstacle to embryonic development through promoting trophoblast apoptosis and inhibiting trophoblast proliferation. ANAs in FF might be an unfavorable factor for the outcome of those who undergo IVF-ET treatment.

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.

Relevance of systematic anti-nuclear antibodies testing after obstetrical complications. J Reprod Immunol 2021; 148:103437.

Abstract
Adverses pregnancy outcomes are commonly encountered with autoimmune disease (AID). Although anti-nuclear antibodies (ANA) are often present several years before AID diagnosis, the importance of ANA testing has not been evaluated in this context. The objective of this study was to determine if ANA discovery after obstetrical complications is associated with a diagnosis of AID and improves the prognosis of subsequent pregnancies. All patients presented at the multidisciplinary board meeting (MBM) "Thrombophilia and Pregnancy", whose ANA were discovered after an obstetrical complication, were included in a multicenter descriptive study. All patients were referred to an internal medicine consultation for diagnosis. Data were collected retrospectively by computer chart analysis and updated by phone. A total of 404 patients were included, of which 50 (12.4 %) had a diagnosis of AID related to ANA. Patients with AID had higher ANA levels (p < 0.001), with more frequent specificity (26%, versus 6.7%, p < 0.0001), and more often persistent (84% versus 30.8%, p < 0.0001) compared to patients without AID. Subsequent pregnancy outcomes were not significantly affected by ANA levels and AID diagnoses. Our study shows that the discovery of ANA after obstetrical complications may lead to an early diagnosis of AID. It makes us reconsider the systematic determination of ANA after an obstetrical event because in the case where ANA are found positive, an adapted follow-up would reduce the negative impact of ANA presence on subsequent pregnancies.

Long Noncoding RNA RP11-115N4.1 Promotes Inflammatory Responses by Interacting With HNRNPH3 and Enhancing the Transcription of HSP70 in Unexplained Recurrent Spontaneous Abortion. Front Immunol 2021; 12:717785. [PMID: 34484222 PMCID: PMC8414257 DOI: 10.3389/fimmu.2021.717785] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 07/27/2021] [Indexed: 12/13/2022] Open
Abstract
Background Unexplained recurrent spontaneous abortion (URSA) is a common pregnancy complication and the etiology is unknown. URSA-associated lncRNAs are expected to be potential biomarkers for diagnosis, and might be related to the disease pathogenesis. Objective To investigate differential lncRNAs in peripheral blood of non-pregnant URSA patients and matched healthy control women and to explore the possible mechanism of differential lncRNAs leading to URSA. Methods We profiled lncRNAs expression in peripheral blood from 5 non-pregnant URSA patients and 5 matched healthy control women by lncRNA microarray analysis. Functions of URSA-associated lncRNAs were further investigated in vitro. Results RP11-115N4.1 was identified as the most differentially expressed lncRNA which was highly upregulated in peripheral blood of non-pregnant URSA patients (P = 3.63E-07, Fold change = 2.96), and this dysregulation was further validated in approximately 26.67% additional patients (4/15). RP11-115N4.1 expression was detected in both lymphocytes and monocytes of human peripheral blood, and in vitro overexpression of RP11-115N4.1 decreased cell proliferation in K562 cells significantly. Furthermore, heat-shock HSP70 genes (HSPA1A and HSPA1B) were found to be significantly upregulated upon RP11-115N4.1 overexpression by transcriptome analysis (HSPA1A (P = 4.39E-08, Fold change = 4.17), HSPA1B (P = 2.26E-06, Fold change = 2.99)). RNA pull down and RNA immunoprecipitation assay (RIP) analysis demonstrated that RP11-115N4.1 bound to HNRNPH3 protein directly, which in turn activate heat-shock proteins (HSP70) analyzed by protein-protein interaction and HNRNPH3 knockdown assays. Most importantly, the high expression of HSP70 was also verified in the serum of URSA patients and the supernatant of K562 cells with RP11-115N4.1 activation, and HSP70 in supernatant can exacerbate inflammatory responses in monocytes by inducing IL-6, IL-1β, and TNF-α and inhibit the migration of trophoblast cells, which might associate with URSA. Conclusion Our results demonstrated that the activation of RP11-115N4.1 can significantly increase the protein level of HSP70 via binding to HNRNPH3, which may modulate the immune responses and related to URSA. Moreover, RP11-115N4.1 may be a novel etiological biomarker and a new therapeutic target for URSA.

Abstract
OBJECTIVE To investigate the therapeutic role of prednisone in patients having unexplained recurrent pregnancy loss (URPL) with positivity of antinuclear antibodies (ANA) and the relationship between ANA titers, prednisone, and pregnancy outcomes. METHODS We included 202 women diagnosed as having URPL with positive ANA at titer of 1:80 or more. Among them, 159 patients receiving prednisone plus aspirin were included as group PA and the remaining 43 patients prescribed aspirin only served as group A. Live birth rates were considered as the primary outcome. Incidence rates of pregnancy complications and outcomes of the newborns were also compared. Additionally, the association between live birth and major clinical variables was studied. RESULTS Live birth rates were comparable between the two groups (93.1% versus 83.7%, P = 0.107). No significant differences were observed regarding the incidence rates of adverse pregnancy outcomes, other pregnancy complications and the fetal outcomes. Alteration of ANA titers after pregnancy compared with pre-conception results was the only significant variable associated with live birth. CONCLUSION Prednisone plus aspirin did not show improved therapeutic effects over aspirin alone in URPL patients with positive ANA. Variation of ANA titers was found to be a prognostic indicator of pregnancy outcomes in these patients.

Clinical features associated with pregnancy outcomes in women with positive antiphospholipid antibodies and previous adverse pregnancy outcomes: a real-world prospective study. Clin Rheumatol 2020; 40:193-204. [PMID: 32514680 DOI: 10.1007/s10067-020-05203-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 05/09/2020] [Accepted: 05/25/2020] [Indexed: 12/21/2022]
Abstract
OBJECTIVE This study aims to analyze factors related to pregnancy outcomes in women with positive antiphospholipid antibodies and previous adverse pregnancy outcomes (APOs) prospectively. METHODS Patients' characteristics were described. Factors associated with obstetric complications were analyzed using logistic regression analysis. RESULTS A total of 128 females with 73.4% non-criteria obstetric antiphospholipid syndrome (NC-OAPS) were included. APOs accounted for 38.3%, of which 65.3% were fetal losses. Live birth rates in criteria OAPS and NC-OAPS were similar (76.5% and 74.5%). For the whole patients, antinuclear antibody (ANA) titer ≥ 1:160 (OR 5.064, 95% CI (1.509, 16.995), P = 0.009) was a risk factor for APOs and low molecular weight heparin (LMWH) use (OR 0.149, 95% CI (0.029, 0.775), P = 0.024)) was a protective factor. Age (OR 1.159, 95% CI (1.011, 1.329), P = 0.034) and previous APOs ≥ 3 times (OR 3.772, 95% CI (1.14, 12.435), P = 0.029) were risk factors for fetal loss, and LMWH use (OR 0.068, 95% CI (0.009, 0.486), P = 0.007) was a protective factor. Regular rheumatology visits was a protective factor for APOs and fetal loss (OR 0.085, 95% CI (0.024, 0.306), P < 0.001; OR 0.019, 95% CI (0.004, 0.104), P < 0.001). The proportion of it decreased in APOs and fetal loss groups (53.1% and 28.1%). Glucocorticoid use was a risk factor for APOs in NC-OAPS and higher serum C3 levels in the first gestational trimester was a protective factor for fetal loss (OR 3.703, 95% CI (1.402, 9.777), P = 0.008; OR 0.041, 95% CI (0.002, 0.947), P = 0.046). CONCLUSION Age, APO history, ANA titer, LWMH and glucocorticoid use, serum C3 levels, and regular rheumatology visits were related to obstetric complications. Key Points • This was one of the few prospective studies focused on patients with positive antiphospholipid antibodies and previous adverse pregnancy outcomes. The majority were NC-OAPS patients. • The study first evaluated the impact of rheumatologists' monitoring based on individual disease assessments on pregnancy outcomes. The live birth proportion was similar in patients with criteria OAPS and NC-OAPS when treated. • Age, APO history (≥ 3 times), ANA titer (≥ 1:160), LMWH use, glucocorticoid use, and serum C3 were factors related to obstetric complications.

Abstract
RPL is a very debated condition, in which many issues concerning definition, etiological factors to investigate or therapies to apply are still controversial. ML could help clinicians to reach an objectiveness in RPL classification and access to care. Our aim was to stratify RPL patients in different risk classes by applying an ML algorithm, through a diagnostic work-up to validate it for the appropriate prognosis and potential therapeutic approach. 734 patients were enrolled and divided into 4 risk classes, according to the numbers of miscarriages. ML method, called Support Vector Machine (SVM), was used to analyze data. Using the whole set of 43 features and the set of the most informative 18 features we obtained comparable results: respectively 81.86 ± 0.35% and 81.71 ± 0.37% Unbalanced Accuracy. Applying the same method, introducing the only features recommended by ESHRE, a correct classification was obtained only in 58.52 ± 0.58%. ML approach could provide a Support Decision System tool to stratify RPL patients and address them objectively to the proper clinical management.

Uterine and placental blood flow indexes and antinuclear autoantibodies in unexplained recurrent pregnancy loss: should they be investigated in pregnancy as correlated potential factors? A retrospective study. BMC Pregnancy Childbirth 2020; 20:44. [PMID: 31959152 PMCID: PMC6971936 DOI: 10.1186/s12884-020-2724-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2019] [Accepted: 01/07/2020] [Indexed: 11/20/2022] Open
Abstract
BACKGROUND The potential role of antinuclear antibodies (ANA) in recurrent pregnancy loss (RPL) pathogenesis is still debated, although some evidences suggest that they could affect pregnancy outcome, leading to a higher miscarriage rate in these patients. A hypothesized mechanism is through changes in uterine flow in pre-conceptional stage, by modifying endometrial receptivity in RPL. However, scant data are available, in pregnancy, about their role in RPL placental perfusion, also in relation to its potential treatments, such as low molecular weight heparin (LMWH). The aim of this study is to retrospectively further investigate the correlation between two-dimensional (2D) and three-dimensional (3D) uterine and placental flow indexes and the presence or the absence of ANA in women with unexplained RPL (uRPL), treated or not treated with LMWH. METHODS 2D Doppler measurement of pulsatility index (PI) of the uterine arteries and 3D ultrasonography determination of vascularization index (VI), flow index (FI) and vascularization flow index (VFI) was carried out with the aid of the virtual organ computer-aided analysis (VOCAL) technique in LMWH treated (n 24) and not treated-uRPL patients (n 20) and in the relative control group (n 27), each group divided in ANA+ and ANA- subgroups. Serum assay for the presence of ANA was performed in all women. RESULTS No differences were found in PI, VFI and VI values, by comparing the different groups. A difference in VI values was found for ANA- patients between RPL women not treated with LMWH and the treated ones (p = 0,01), which have lower VI values and similar to controls. By considering only ANA- treated and not treated RPL patients, the ROC curve shows an area of 0,80 and at the VI cut-off of 11,08 a sensitivity of 85% and a specificity of 67%. CONCLUSIONS LMWH could exert a potential beneficial effect in restoring the physiological blood flow supply in terms of VI in uRPL ANA- status, suggesting to include ANA and VI investigations in the RPL diagnostic algorithm in a research context, since further studies are needed to clarify this challenging hypothesis in order to try to ameliorate ANA and abnormal placental vascularization negative influence on RPL pregnancy outcome .

Abstract
In the present manuscript, we review the recent research investigating the pathogenic association between most studied autoantibodies and recurrent pregnancy loss. Pregnancy loss represents a common obstetric complication occurring in about 15%-25% of all clinically recognized pregnancies. The recurrence of pregnancy loss identifies a distinct clinical entity, that is recurrent pregnancy loss (RPL), affecting about 2%-4% of couples. Several factors, including age, chromosomal abnormalities, uterine anomalies, thrombophilic disorders, endocrinopathies, hormonal and metabolic disorders, infections, sperm quality, and lifestyle issues, are involved in RPL. The role of autoantibodies in RPL is only partially determined. In some cases (antiphospholipid antibodies [aPL]), their involvement is well established. In other cases (anti-thyroid autoantibodies, antinuclear, anti-transglutaminase, and anti-endomysial antibodies), it is still debated, despite multiple, although not fully conclusive, evidences strongly suggest a possible involvement in RPL. Further extensive research is needed to definitively confirm or exclude their actual role.

Abstract
BACKGROUND The direct role of antiphospholipid antibodies (aPL) at maternal-fetal interface has not been fully investigated, especially whether they are involved in physiological and pathological implantation conditions, in an antiphospholipid syndrome (APS)-independent manner. In fact, trophoblast cells and placental endothelial cells at the implantation site express potential aPL targeted-phospholipid antigens (PL Ags); thus, the local production and presence of their specific antibodies, not related to APS (characterized by aPL presence in the peripheral blood), could be a potential marker of aberrant invasion, implantation and fetal-maternal immune tolerance processes. METHODS Anti-Beta2glycoprotein I (anti-β2GPI) and anticardiolipin (aCL Ab) antibodies (the most clinically relevant aPL) were detected by immunoenzymatic assay (ELISA), in the amniotic fluid (AF) of 167 women with physiological and complicated common pregnancy conditions, sharing an aberrant implantation process, such as recurrent pregnancy loss (RPL), autoimmune hypothyroidism (ahT) and smoking. All women included in the study were negative to peripheral blood aPL. RESULTS aCL and anti-β2GPI antibodies were detectable in all the AF samples. RPL, ahT and smoking patients had higher level of anti-β2GPI Abs (IgM) compared to women with physiological pregnancies (p < 0.0001). Since IgM cannot cross the placenta, their local production in response to maternal-fetal interface stimuli, could be hypothesized. CONCLUSIONS The presence of aPL in the AF (not related to APS) could reveal a potential clinical significance at maternal-fetal interface in selected pregnancy complications, in which an aberrant implantation process, and in turn an impaired fetal-maternal immune tolerance cross-talk, could occur.

Abstract
PROBLEM Several recent studies have investigated the relationship between antinuclear antibodies (ANAs) and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. This meta-analysis evaluated the effect of ANA on clinical outcome for patients undergoing IVF/ICSI treatment. METHOD OF STUDY A systemic survey of the literature was performed using PubMed, EMBASE and the Cochrane Library databases, through January 2019. Evaluated outcomes included clinical pregnancy rate (CPR), miscarriage rate (MR) and implantation rate (IR). Relative risk ratio (RR) and 95% confidence intervals (95% CI) were used for dichotomous data. Meta-analyses were performed with Review Manager 5.3 software. RESULTS Eleven eligible studies were found. For IVF/ICSI cycles, compared with an ANA(-) group, infertile patients with ANA(+) had significantly reduced incidence of CPR (RR 0.66, 95% CI 0.56-0.79; I2 = 60%) and IR (RR 0.61, 95% CI 0.49-0.76; I2 = 75%), and had a higher MR (RR 1.81, 95% CI 1.40-2.36; I2 = 48%). CONCLUSION This study suggested that ANA might cause poor pregnancy outcomes for infertile women undergoing IVF/ICSI treatment.

Abstract
In vitro fertilization-embryo transfer (IVF-ET) can be used by infertile couples to assist with reproduction; however, failure of the embryo to implant into the endometrial lining results in failure of the IVF treatment. The present study investigated the expression of chemokine receptor 7 (CCR7)(lo) programmed death-1(PD-1)(hi) chemokine receptor type 5 (CXCR5)+ cluster of differentiation 4 (CD4)+ T cells and associated factors in patients with repeated implantation failure (RIF). A total of 30 females with RIF and 30 healthy females were enrolled in the current study. Flow cytometry was used to detect the proportion of CCR7(lo)PD-1(hi) CXCR5+ CD4+ T cells in the peripheral blood. Cytokine bead arrays were performed to detect the levels of interleukin (IL)-6, −4 and −2 in the serum. ELISAs were used to detect the level of IL-21 in the serum. Quantitative real time polymerase chain reaction analysis and immunohistochemistry were used to investigate the expression of B-cell lymphoma 6 (Bcl-6), chemokine receptor type 5 (CXCR5) and IL-21 in the endometrium. The results revealed that the percentage of CCR7(lo)PD-1(hi) CXCR5+ CD4+ T cells was increased in the RIF group compared with the control group during the mid luteal phase. The mRNA and protein levels of Bcl-6, IL-21 and CXCR5 in the endometrium and the concentrations of IL-21 and IL-6 in the serum were significantly increased in the RIF group; however, no significant difference was observed between the two groups in regards to the expression of IL-4 and IL-2. Furthermore, a significant positive correlation was identified between the percentage of CCR7(lo)PD-1(hi) CXCR5+ CD4+ T cells and IL-21 and IL-6 levels. The expression of IL-21 also had a positive correlation with Bcl-6 and CXCR5 expression in the RIF group. These results suggest that increased levels of CCR7(lo)PD-1(hi) CXCR5+ CD4+ T cells and associated factors contribute to RIF and could therefore be a potential therapeutic target.

Abstract
AIMS The aim of this study was to evaluate the expression of OLR1 and its alternative splicing isoform Loxin in unexplained recurrent miscarriage (uRM). METHODS Sixty-three women of reproductive age were recruited and were divided into four groups: 18 pregnant and 23 non-pregnant women with uRM, and 12 pregnant and 10 non-pregnant women with physiological pregnancies. Complementary DNA derived from peripheral blood mononuclear cells (PBMCs) was analyzed by quantitative real-time PCR to evaluate the expression of OLR1 and Loxin. Oxidized low-density lipoproteins (ox-LDLs) were assayed from serum by a commercially available kit. RESULTS Pregnant uRM women presented with a higher, though not significant, OLR1/Loxin ratio and a higher ox-LDLs serum level (p ≤ 0.05) compared with pregnant control women. OLR1 and Loxin levels were significantly decreased in non-pregnant uRM women compared with the control (OLR1: 0.00018 vs. 0.00043, p ≤ 0.005; Loxin: 0.00018 vs. 0.00060, p ≤ 0.005, respectively). Loxin expression decreased by about two-thirds (p ≤ 0.005) in pregnant women compared with non-pregnant control women. A higher expression of OLR1 in pregnant women compared with non-pregnant women with uRM (p ≤ 0.05) was observed, but no variation in Loxin expression was observed. CONCLUSIONS The results of this study show an association of peripheral OLR1 and Loxin expression levels in uRM women, and they suggest the possible existence of an uncontrolled oxidative stress in these women in the first trimester of pregnancy.
