IL-33 and Soluble ST2 Are Associated With Recurrent Spontaneous Abortion in Early Pregnancy

Normal pregnancy is related to the successful transition from type 1 cellular immunity to type 2 cellular immunity. Therefore, this study aimed to investigate whether there is abnormal expression of cytokines in the process of inducing Recurrent spontaneous abortion (RSA). Interleukin (IL)-33 is a new member of the IL-1 family, and ST2, as IL-33’s receptor, induced the production of type 2 cytokines. In this study, blood samples were collected from 19 non-pregnant women of normal childbearing age, 28 normal pregnant women, and 33 women with RSA. The serum concentrations of IL-33 and ST2 were detected by flow cytometry. Our results showed that the serum concentrations of IL-33 and ST2 in the RSA group were significantly higher than those in the healthy control group (IL-33: P < 0.05; ST2: P < 0.0001), and IL-33 and ST2 had a higher level in the process of RSA predictive value. In addition, this study initially found that the serum concentrations of IL-33 and ST2 were not significantly correlated with the number of weeks of pregnancy, and there was a lower correlation between IL-33 and ST2 during RSA. This result may be related to the small number of cases. This study is the first time to correlate the changes in serum concentrations of IL-33 and ST2 with RSA, which may be a novel biomarker for the prediction and treatment of RSA.

Immunological Rejection

Disorder of maternal immune responses during pregnancy triggers immunological rejection of fetus antigens by maternal immune components, contribute to spontaneous abortion or miscarriage. The study was designed to concentrated on immunoglobulins (IgM, IgG and IgA) and complement elements (C3 and C4) serum levels changes in normal pregnant and abortion women. Study groups were classified into normal pregnant women (20), spontaneous abortion (30) and non-pregnant women (16) as a control group, attending to Shahid Dr. Khalid Hospital/Department of Gynecology and Obstetrics/Koya city. Serum levels of immunoglobulins (IgG, IgM, and IgA), complement proteins (C3 and C4) were determined and analyzed for normal pregnant, abortion and control groups by using Single Radial Immunodiffusion (SRID) technique. The results demonstrated that concentration of IgG levels in abortion differed significantly in compare to normal pregnancy (p ≤0.05), while there were no significant differences in IgM and IgA serum levels among groups (p >0.05). Also, statistical analysis revealed that serum levels of C3 and C4 significantly decreased in abortion group compared to normal pregnant and non-pregnant groups (p ≤0.05). Concluded that complement proteins (C3 andC4) are a good defense line during normal pregnancy, sometime activation (hyper-consuming) of complement elements may provoke spontaneous abortion, while immunoglobulins are a little role in inducing of miscarriage in pregnant women.

Recurrent miscarriage, defined as loss of two or more consecutive pregnancies, occurs in 1–2% of couples attempting to bear children. The major causes of recurrent pregnancy loss (RPL) based on the literature include parental structural chromosome rearrangement, immunologic factors (i.e. antiphospholipid syndrome), thrombophilic factors (both inherited and acquired), anatomic factors of uterine anomalies, and endocrinologic disorders. Luteal phase defect, polycystic ovarian syndrome (PCOS), diabetes mellitus, thyroid disease and hyperprolactinemia are among the endocrinologic disorders implicated in approximately 17% to 20% of RPL. The prevalence of hypothyroidism in the general population of reproductive age is about 2-3%. The aim of this study is to observe the benefit of screening for hypothyroidism amongst women with recurrent spontaneous abortion early in the first trimester. The study included one hundred and sixty (160) women, in the reproductive age of life, where there ages ranged from 20 – 33 years, and divided into two groups. Study group which included eighty (80), non pregnant women with a history of two or more consecutive spontaneous abortions early in the first trimester, with no living children and control group which included eighty (80), non pregnant women having one or more living children without any history of abortion. Hypothyroidism was noted in ten (10) cases (12.5%) in the study group and noted in two (2) cases (2.5%) in the control group with a statistically significant difference (P < 0.01). The mean levels of TSH in the study group was 22.71  13.13 Iu/ml. Conclusion: Screening for hypothyroidism has clinical significance and would help to reduce miscarriage rate in women with recurrent spontaneous abortion.

Pregnant women with intrauterine growth restriction (IUGR) have an increased risk of adverse perinatal and long-term complications compared with the birth of children with normal body weight. Thus, IUGR is one of the main challenges for the global health system, especially in poor and developing countries. Morpho-functional studies of the placentas help in determining the causes of IUGR, and therefore, timely prevent complications in pregnant women with IUGR. The objective: The purpose of this study is to investigate various morphometric and pathomorphological changes in the placenta, including inflammatory, in cases of IUGR, and to establish a correlation of these results with the etiology and complications for the fetus. Materials and methods. In the current study, 54 placentas of the fetuses with IUGR (the main group) were compared with 50 placentas of the fetuses with normal development (control group). The criteria for the inclusion of IUGR were gestational age more than 30 weeks and all fetuses with a weight less than 10th percentile for this period of pregnancy. The placenta material was studied pathomorphologically with laboratory screening for infection and inflammation. Similarly, the results were determined for placentas of the fetuses with normal development compared to placentas with IUGR. Results. The placenta study showed the presence of calcification in the case of IUGR, as well as in the case of prolonged pregnancy. However, calcification of the placenta in the case of IUGR was more progressive compared with placenta in the normal pregnancy. In addition, the presence of intrauterine infection and inflammation was observed, which could also lead to an adverse outcome for the further progression of pregnancy with IUGR. Conclusion. A comparative macro- and microscopic pathomorphological study of the placentas in the two groups has shown a significant increase in the pathological changes in all the anatomical structures of the fetuses with IUGR. Key words: Intrauterine growth restriction (IUGR), fetal weight, pathomorphological changes of the placenta.

Abstract Background To investigate the correlation between the thickness of epicardial adipose tissue (EAT), C-reactive protein (CRP), interleukin (IL) -6, visfatin, juxtaposed with another zinc finger protein 1 (JAZF1) and type 2 diabetic mellitus (T2DM) macroangiopathy. Methods The study enrolled 82 patients with T2DM with macroangiopathy (the Complication Group), and 85 patients with T2DM (the Diabetes Group) who were admitted to Shandong Provincial Third Hospital from February 2018 to February 2020. In addition, 90 healthy people who underwent physical examination at the same hospital during the same period were enrolled (the Healthy Control Group). Age, gender, height, weight, waist circumference (WC), hip circumference (HC), diabetic course and therapeutic drugs, waist hip ratio (WHR), and body mass index (BMI) were recorded and calculated. Results The baseline characteristics of the three groups were comparable, and the diabetic course of the Complication Group and the Diabetes Group was not significantly different (P > 0.05). The WHR of the Complication Group was higher than that of the Diabetes Group and the Healthy Control Group, with statistical significance (P < 0.05). The FPG, 2hPG, HbA1C, CRP, IL-6, Visfatin, JAZF1, HOMA-IR, EAT thickness, and baPWV of the Complication Group were all higher than those of the Diabetes Group and the Healthy Control Group (P < 0.05, respectively). The JAZF1 and FIns of the Complication Group and Diabetes Group were lower than those of the Healthy Control Group, and JAZF1 of the Complication Group was lower than the Diabetes Group with statistical significance (P<0.05, respectively). Pearson correlation analysis showed that the EAT thickness was positively correlated with CRP, IL-6, visfatin, and JAZF1 (r = 0.387, 0.451, 0.283, 0.301, respectively, all P<0.001). Pearson correlation analysis showed that baPWV was positively correlated with EAT thickness, CRP, IL-6, visfatin, and JAZF1 (r = 0.293, 0.382, 0.473, 0.286, respectively, all P < 0.001). Multivariate stepwise regression analysis showed that FPG, 2hPG, HbA1C, CRP, IL-6, visfatin, JAZF1, and EAT thickness were independent risk factors that affected T2DM macroangiopathy. Conclusions Clinical monitoring and treatment of T2DM macroangiopathy can use CRP, IL-6, Visfatin, JAZF1, and EAT thickness as new targets to delay the progression of the disease. Further research on the relationship between the above factors and the pathogenesis of T2DM macroangiopathy may be helpful provide new treatment strategies.

Roberts J. Jenkins C, Wilson R, Pearson C, Franklin IA, MacLean MA, McKillop JH, Walker JJ. Recurrent miscarriage is associated with increased numbers of CD5/20 positive lymphocytes and an increased incidence of thyroid antibodies. Eur J Endocrinol 1996;134:84–6. ISSN 0804–4643 The aim of this study was to determine whether recurrent miscarriage (three or more miscarriages, no live children) was associated with an increased incidence of autoantibodies. Five groups were enrolled into the study; healthy non-pregnant women, healthy first-trimester pregnant women, women suffering spontaneous abortion, those undergoing termination of pregnancy and those with a previous history of miscarriage. The number of total B cells and the numbers of the antibody producing B cell subset CD5+/CD20+ were determined for each group. Samples were tested for anticardiolipin antibodies, antinuclear antibodies and thyroid microsomal and thyroglobulin antibodies. The results showed that compared to normal pregnancy or spontaneous abortion, recurrent miscarriage was associated with a significant increase in the number of CD5+/20+ positive cells (0.8 ± 0.3 vs 0.5 ± 0.1 vs 1.1 ± 0.3 × 108/l: p < 0.001). These women were also found to have a higher incidence of thyroid antibodies, with four out of the 11 patients being positive for thyroid microsomal antibodies. These results suggest that there may be an association between autoimmunity and recurrent miscarriage.

Transcriptional Gene Regulation

MicroRNAs (miRNAs) are non-coding RNA molecules of about 22 nucleotides that involved in post-transcriptional gene regulation. Evidence indicates that miRNAs play essential roles in endometriosis, pre-eclampsia, infertility and other reproductive system diseases. However, whether miRNAs are involved in recurrent spontaneous abortion (RSA) is unclear. In this work, we analysed the miRNA expression profiles in six pairs of villus or decidua from RSA patients and normal pregnancy (NP) women using a human miRNA microarray. Some of the chip results were confirmed by RT-qPCR. In the villi of RSA patients, expression of hsa-miR-184, hsa-miR-187 and hsa-miR-125b-2 was significantly higher, while expression of hsa-miR-520f, hsa-miR-3175 and hsa-miR-4672 was significantly lower, comparing with those of NP control. As well, a total of five miRNAs (hsa-miR-517c, hsa-miR-519a-1, hsa-miR-522, hsa-miR-520h and hsa-miR-184) were upregulated in the decidua of RSA patients. The target genes of these differentially expressed miRNAs were predicted by miRWalk, and we speculate a network of miRNA regulating RSA by target genes function on adhesion, apoptosis and angiogenesis. Our study may help clarify the molecular mechanisms which are involved in the progression of RSA, and provide a reference for future research.

Backround: Elabela (ELA) is a hormone that is secreted at high levels in the kidneys of a healthy adult. This study aims to investigate whether serum ELA levels of patients with Type 2 Diabetes vary with the severity of renal damage. Methods: Our study included 50 healthy control subjects and 100 diabetic patients, who were categorized into groups based on urine albumin/creatinine ratios (ACR). Patients included in the study were assigned to four groups: Group 1 (healthy control), Group 2 (ACR<29mg/g), Group 3 (ACR=30-299 mg/g), and Group 4 (ACR>300 mg/g normal or high serum creatinine). Physical examination findings, demographic characteristics of the study group were recorded, and serum ELA levels and other laboratory parameters were assessed using appropriate methods. Results: The results of the study indicated that ELA levels determined in healthy individuals gradually decreased through stages of normal albuminuria, microalbuminuria, and macroalbuminuria. Moreover, ELA had a significant negative corre- lation with LDL-C (r=-0.201, p=0.014), glucose (r=-0.437, P<0.001), retinopathy (r=-0.222, P=0.006), serum BUN (r=- 0.161, P=0.049), and a positive correlation with eGFR (r=0.250, P=0.002). Conclusions: The fact that ELA levels are higher in healthy individuals compared to diabetic patients without microalbu- minuria, and higher in diabetic patients without microalbuminuria compared to patients with advanced albuminuria and kidney damage, suggests that the ELA level can be an important clinical prognostic variable and even a promising agent for the treatment of diabetic nephropathy patients.

Objective: Spontaneous abortion is the most common complication of early pregnancy, affecting up to 20% of recognized pregnancies. Kisspeptin is predominantly released by placental syncytiotrophoblasts, and regulates their placental invasion into the uterine matrices. We aimed to establish an association of serum kisspeptin levels with pregnancy outcomes during the early gestational stage of the first trimester. Method: In this prospective study, 90 pregnant women in their 7 to 8 6/7 gestational weeks were classified into three groups: (i) The control group, consisting of healthy pregnant women (n=30), (ii) the threatened abortion group (n=30), and (iii) the spontaneous abortion group (n=30). The maternal serum samples were analyzed for complete blood count parameters and kisspeptin levels. Results: There was no statistical difference regarding body mass index (BMI) and gestational age (p=0.370). Regarding detailed obstetric notations, including gravida, parity, abortion, and living children, socioeconomic levels, and employment rates, all study groups were comparable (p>0.05, for all). No significant association was found regarding the biochemical parameters of complete blood count, including neutrophil, lymphocyte, and platelet concentrations, as well as neutrophil-to-lymphocyte ratios (NLR) and platelet-to-lymphocyte ratios (PLR) (p>0.05, for all). The median serum kisspeptin levels of the study groups did not differ between the groups (p=0.153). Correlation analysis revealed no significant relationship between serum kisspeptin levels and other study parameters in any study groups (p>0.05, for all) Conclusions: We found no statistically significant relationship between serum kisspeptin concentrations and pregnancy outcomes in the early gestational stage of the first trimester, and serum kisspeptin concentrations did not seem to be a reliable marker to distinguish abortion status from viable pregnancy

Hematological Changes

Background: Various hematological and immunological changes can occur in pregnancy which could be beneficial for the growth of the fetus and the maintenance of the pregnancy although some of these changes could be hazardous to the fetus and can cause complications during pregnancy. Thus, this study was conducted to investigate the hematological and immunological changes in normal pregnancy and preeclampsia (PE). Materials and Methods: To this end, hematological and immunological changes were evaluated in 62 normal pregnant women and 56 pregnant women with PE. Moreover, 58 healthy non-pregnant women were studied as the control group. The study was done between December 1, 2018 to May 1, 2019 in Chwarbakh Private Clinic and Shorsh Teaching Hospital. The venous peripheral blood from the antecubital vein was used in this study. Results: The results revealed a significant increase in the number of granulocytes, monocytes, and mean platelet (PLT) volume in both normal pregnant women and PE patients in comparison to normal (non-pregnant) controls (P<0.01). In addition, there was a significant correlation between a reduction in their hematocrit (HCT), PLT, and lymphocytes (P<0.01). With regard to immunological changes, a significant increase was also observed in the serum interleukin-4 (IL-4) levels in both normal pregnancy and preeclamptic patients when compared to non-pregnant controls (P<0.01), but gamma interferon was not significantly different. Conversely, there were no significant associations between the serum level of antiphospholipid antibodies and anticardiolipin antibodies in the study groups except for antiphospholipid antibodies which were significantly lower in the third trimester of pregnancy in the preeclamptic patients (P<0.05). Conclusion: In general, significant changes in hematological and immunological parameters were observed in both normal pregnant and PE patients although further studies are required to include more immunological parameters.
