Abstract
BACKGROUND Vitamin D insufficiency and deficiency can be associated with adverse effects on pregnancy outcomes, which may include recurrent pregnancy loss through the mechanisms that are yet unknown. The aim of this study was to evaluate the effect of 1,25VitD3 on regulatory T cells (Tregs) and T helper17 (Th17) cell populations In vitro in unexplained recurrent pregnancy loss (URPL) patients and healthy women. METHODS Samples from 20 non-pregnant women with a history of URPL were compared to 20 normal non-pregnant women. Peripheral blood mononuclear cells (PBMC) were divided into 3 wells for each subject: in the presence of 1, 25 VitD3 (50 nM, for 16 hours), PHA (positive control) (10μM), and without any treatment (as a baseline or negative control). The percentage of regulatory T cells and Th17 cells was measured by flow cytometry at baseline and then after cell culture experiments. RESULTS Our study indicated that the percentage of Tregs in patients with URPL was significantly lower than the control group (2.42 ± 0.27 vs. 3.41 ± 0.29, P= 0.01). The percentage of Th17 cells was significantly greater in URPL patients compared to the control group (2.91 ± 0.33 vs. 1.18± 0.15, P=0.001). 1, 25VitD3 treatment significantly increased the percentage of Tregs from the baseline in the URPL group compared to that in the control group (1.23 ± 0.03 vs. 1.00 ± 0.03, P= 0.01). CONCLUSION Vitamin D deficiency may be a contributor to recurrent pregnancy loss and suggests supplementation of women with Vit D pre-pregnancy may be protective against URPL.

Abstract
Recurrent pregnancy loss (RPL) commonly refers to three or more miscarriages that occur before 20 weeks of pregnancy. The immunological cause of RPL could be either an auto- or alloimmune-related event or both. Because of the discovery of immunological abnormalities in RPL patients in clinical practice, several immunomodulatory therapies were introduced to maintain the immune balance at the maternal-fetal interface. Intravenous immunoglobulin (IVIg) is one of the immunomodulators. In recent years, several studies have analyzed the therapeutic effect of IVIg on RPL patients with antiphospholipid syndrome (APS) or unexplained RPL. However, their results are controversial. IVIg can be used in RPL patients with APS who have previously failed in other treatments. It is recommended that IVIg infusion could be considered used before conception in RPL patients who have cellular immune abnormalities such as increased natural killer (NK) cell counts, NK cell cytotoxicity, or increased T helper (Th)1/Th2 ratio, depending on the cut-off values of each hospital. The aim of this review was to summarize the mechanisms, efficacy, pharmacokinetics, and side effects associated with passive immunization using IVIg in immunologic RPL, according to the literature published in recent years. We hope that more obstetricians will be able to understand the timing and indication of IVIg properly in immunologic RPL patients and effectively enhance pregnancy outcomes for mothers and neonates.

Abstract
Background: Vitamin D insufficiency and deficiency can be associated with adverse effects on fetus and pregnancy outcomes. This study aimed at evaluating the effect of 1,25VitD3 on specific transcription factor and markers of Tregs and Th17 cells in PBMCs of women with URPL as a case group and PBMCs of healthy women as a control group. Methods: Samples from 20 non-pregnant patients with a history of URPL were compared to 20 normal non-pregnant women. PBMCs were divided into three wells for each subject in the presence of 1,25VitD3 (50 nM, for 16 hours), PHA (10 µM; positive control), and without any treatment (negative control). By Real-time PCR (Taqman assay), specific transcription factors of Tregs and Th17 cells, FOXP3, ROR-γt, GITR, and CTLA-4 mRNA expressions in two groups were measured. Results: FOXP3/ROR-γt mRNA expression in PBMCs decreased significantly in women experiencing URPL compared to the control group (p = 0.0001). Although 1,25VitD3 (50 nM) increased FOXP3 gene expression (p = 0.0001), it did not significantly affect ROR-γt gene expression. Besides, 1,25VitD3 treatment significantly increased FOXP3/ROR-γt mRNA expression from baseline in PBMCs of the fetal loss group compared to that of the control group (p = 0.01). The 1,25VitD3 also increased GITR gene expression (p = 0.017) in PBMCs of URPL women compared to the controls. Conclusion: Vitamin D deficiency may be a contributor to recurrent pregnancy loss and suggests that the supplementation of women with Vitamin D pre-pregnancy may be protective against URPL via affecting Tregs signature genes, FOXP3 and GITR.

Abstract
Objective One of the most important problems in human reproduction is recurrent pregnancy loss (RPL). RPL is defined as three or more consecutive abortions in the first trimester of pregnancy. The association between the polymorphisms in the immunological factors and RPL was investigated. The aim of our study was to determine the association of interleukin receptor antagonist (IL-IRN) and interleukin-1β (IL-1β) polymorphisms with RPL in Iranian Azeri women. Materials and methods The study participants consisted of 100 women with RPL of Iranian Azeri origin. The control group comprised 100 age- and ethnically-matched healthy women of the same reproductive age. Genomic DNA was extracted from the whole blood and genotype determinations were performed using polymerase chain reaction (PCR) amplification followed by restriction fragment length polymorphism (RFLP) analysis. Results Our results showed no significant relationship between IL-1RN polymorphism and RPL. The homozygous state in -857 C/T variant was seen to be higher in RPL patients than in control subjects. Also frequency of wild type genotype was lower in RPL patients than in controls. However, this associations was not significant. Conclusion This study suggested that -511 C/T (rs16944) and -31 C/T (rs1143627) polymorphisms in IL-1β gene may not be involved in RPL in Iranian Azeri women. Also the promoter polymorphism of the IL-1RN gene may not play a role in the susceptibility to RPL.

Abstract
Recurrent pregnancy loss (RPL), which occurs in 0.5%-1% of total pregnancies, is usually defined as three or more consecutive spontaneous abortions before 20 weeks of gestation. Although an immunology-based etiology underlying unexplained RPL has been demonstrated, the exact molecular mechanisms are still poorly understood. Recent studies using transcriptomics and proteomics have implicated several factors. Here, we review the key possible mechanisms, in particular immunological abnormalities and thrombophilic aberration, that might underlie RPL. Taken together, these findings provide insight into the development of effective therapeutics for RPL.

Abstract
Genetic factors may contribute to the development of an aberrant pro-inflammatory immune response during pregnancy, thereby increasing the risk of some pregnancy-related pathologies such as recurrent spontaneous abortion (RSA). Interleukin 1 receptor antagonist is an important anti-inflammatory molecule encoded by the IL1RN gene, in which an intronic polymorphism has been described. Even though the molecular genetic mechanisms are not understood, this non-coding polymorphism, and especially IL1RN*2, has been associated with several chronic inflammatory and autoimmune diseases. IL1RN*2 is also associated with increased activity of IL-1beta, which is an important pro-inflammatory cytokine. We investigated the genetic variants of IL1RN in 37 Finnish women with RSA and 800 randomly selected Finnish blood donors. The women with RSA showed a significantly increased frequency of genotypes bearing the rare allele IL1RN*3 compared to the blood donors (10.8 vs 2.1%, odds ratio 5.6, 95% CI: 1.5-19.0, P=0.006). Our results suggest that IL1RN polymorphisms may predispose to RSA in a small subgroup of patients.
