Pon1 Polymorphisms

Abstract Objective The aim of the present study was to examine the relation between the PON1 polymorphisms and recurrent pregnancy loss (RPL). Methods In a cross-sectional study, blood samples were collected from 100 females. DNA was extracted and PON1 genotypes were determined by polymerase chain reaction (PCR) amplification. Results Regarding PON1 L55M, the mutated allele (M) frequency was found in 70.5% in RPL and in 53.5% in controls; the M allele was significantly associated with an increased risk of RPL (adjusted odds ratio [ORadj] = 2.07; 95% confidence interval [CI]; p < 0.001). However, regarding PON1 Q192R, the R mutated allele frequency was found in 28.5% in RPL and in 33% in controls. The R allele did not show any risk for RPL (ORadj 0.81; 95%CI; p = 0.329). Conclusion The present study suggests that there is an effect of genetic polymorphism on RPL and provides additional evidence that combines with the growing information about the ways in which certain PON1 genotypes can affect the development of the fetus in the uterus.

Background and objectives: Thyroid autoimmunity (TAI) has been associated with a significantly increased risk of miscarriage in women with recurrent pregnancy loss (RPL). The aim of this study was to determine the prevalence of TAI in women with RPL and compare the clinical characteristics of positive and negative TAI women. Materials and Methods: This is a retrospective cross-sectional study; 203 women with RPL were included. Thyroid profile, anti-thyroid peroxidase (TPO-Ab), and anti-thyroglobulin (TG-Ab) antibodies were measured in all participants. Clinical characteristics and causes of RPL were compared between positive and negative TAI. Results: Prevalence of TAI was 14.8%; prevalence of positive TPO-Ab and TG-Ab was 12.3% and 4.9%, respectively. Women with TAI had significantly higher concentrations of thyrotropin (TSH) compared to women without TAI (4.8 ± 3.8 versus 3.1 ± 1.1, p = 0.001). There was no significant difference in age, the number of gestations, miscarriages, state of antiphospholipid antibodies (aPL), or causes of RPL between women that were TAI-positive versus TAI-negative. Prevalence of positive TAI by cause of RPL was: endocrine 7/25 (28%), genetic 1/5 (20%), autoimmune 1/5 (20%), anatomic 8/55 (14.5%), and unexplained cause 13/112 (11.6%). Conclusions: The prevalence of TAI in women with RPL is 14.8%. Women with an endocrine cause have the highest prevalence of TAI.

Abstract Background Promoter region SNPs in TNF-α have been studied in association with Recurrent Pregnancy Loss (RPL) occurrence in various populations. Among them, −238G > A, −308G > A and − 376G > A have been frequently investigated for their potential role in recurrent abortions. The aim of the present study is to evaluate the correlation among TNF-α 238, TNF-α 308 and TNF-α 376 polymorphisms and recurrent pregnancy loss risk in Greek women. Methods This study included 94 Caucasian women with at least two miscarriages of unexplained aetiology, before the 20th week of gestation. The control group consisted of 89 Caucasian women of proven fertility, with no history of pregnancy loss. DNA samples were subjected to PCR amplification using specific primers. Sanger sequencing was applied to investigate the presence of TNF-α 238, TNF-α 308, TNF-α 376 polymorphisms in all samples. Results The TNF-α 238 and TNF-α 308 variants were both detected in RPL and control groups (7.45% vs 4.49 and 45.16% vs 36.73%, respectively), but with no statistically significant association (p-value 0.396 and 0.374, respectively). The TNF-α 376 variant was not detected at all in both control and RPL groups. When TNF-α 238 and TNF-α 308 genotypes were combined no association with RPL was detected (p-value = 0.694). In subgroup analysis by parity, RPL patients carrying the A allele reported less previous births. Conclusions This is the first study demonstrating TNF-α 238 and TNF-α 308 gene expression and the absence of TNF-α 376 variant in Greek women with RPL. However, no association emerged between each polymorphism studied and the occurrence of recurrent pregnancy loss. Accordingly, TNF-α -308G > A, −238G > A and -376G > A variants are not considered genetic markers for identifying women at increased risk of recurrent pregnancy loss in the Greek population.

Thrombophilia gene variants have been shown to be associated with higher risk of recurrent pregnancy loss (RPL). Due to the role of human platelets antigen 1 (HPA-1) and fibrinogen β chain (FGB) as critical players in the coagulation process, their most important variants including rs5918 T > C and rs1800790 G > A were selected to be studied in women affected by RPL. Three milliliters of peripheral blood were drawn from 110 women with history of at least two consecutive spontaneous abortion and 110 healthy women controls. rs5918 T > C and rs1800790 G > A of HPA-1 and FGB genes, respectively, were selected to be analyzed through polymerase chain reaction-restriction fragment length polymorphism (PCR_RFLP) following DNA isolation using QIAamp DNA Blood Mini Kit. Heterozygote genotype (TC) of HPA-1 gene rs5918 polymorphism was significantly associated with risk of RPL (p-value = 0.02). Although, rs1800790 G > A of FGB gene was not associated with RPL, its combination with rs5918 polymorphism was associated with increased risk of RPL. Owing to the critical roles of FGB and HPA-1 genes in coagulation, and thrombosis and several confinements on the meaningful association between the combination of those polymorphism with risk of RPL, including them in the thrombophilia panel may increase detection rate of hereditary thrombophilia patients. However, further studies with larger sample sizes are required to shed light on the exact role of the studied gene polymorphism, especially rs1800790 G > A of FGB gene variant in pathogenesis of RPL.

Background: When clinical pregnancy is established, the risk of spontaneous pregnancy loss is ~12-14%, and therefore the incidence of Recurrent Pregnancy Loss (RPL) by chance alone would be in the order of 0.35%. It occurs in 0.5-3% of women. The objective of this study was to evaluate the obstetric outcome in pregnancies with history of one or more abortions.Methods: It is a retrospective cross-sectional study done at Obstetrics and Gynecology Department, Dr. B. R. Ambedkar Medical College and Hospital, Bangalore. Record review of cases was done from January 2005 to December 2009. Inclusion criteria were pregnancies with history of previous abortions.Results: There were 400 cases with previous history of abortions. There were 266 (66.4%) booked cases while 134 (33.5%) were unbooked cases. 272 (68.0%) patients crossed viable period of pregnancy (more than 28 weeks). Around 56 (14.0%) cases had repeat abortions, 276 (69.0%) cases underwent vaginal delivery and 124 (31.0%) underwent cesarean section. Almost 91 (22.8%) of Babies were low birth weight while others were above 2.5 kg. There were 52 (13.0%) preterm babies and 28 (7.0%) Intrauterine demise of fetuses.Conclusions: Patients with previous history of abortions are at increased risk of adverse maternal and perinatal outcome.

Introduction: Mid trimester of pregnancy is relatively a safe time of pregnancy with minimal and no complications. Mid trimester pregnancy loss constitutes 1 to 5 % of total miscarriages. The purpose of this study is to evaluate the causes of second trimester miscarriages so as to improve the outcome in future pregnancies. Materials & Methods: This was a prospective cross-sectional study. Demographic features, relevant information and risk factors were recorded in a predesigned proforma. Detailed history was followed by thorough clinical examination and appropriate investigations were advised. Results: Total number of miscarriages admitted in the unit over the period of two years were 336 and among them 30 patients presented with second trimester miscarriages (8.9%). The mean age of the patients was 31.4 years. In 19 patients (63.4%) there were identifiable causes for the miscarriage. 7 patients (23.33%) had fibroids in the uterus, 5 patients (16.67%) had bacterial vaginosis, 4 patients (13.33%) had cervical incompetence and in 3 patients (10%) there were congenital abnormalities in the uterus. Conclusion: Patients with second trimester pregnancy loss are at significantly increased risk (10 times more likely) for recurrent second trimester loss. In 50 to 70% of patients no cause can be identified. After single loss there is 80% chance of successful pregnancy outcome in future. Even after two and three mid trimester losses still there is 60% chance of alive pregnancy next time, so thorough evaluation and management plan is needed to prevent this mishap in future pregnancies.

Aim. Celiac disease (CD) is a multifactorial pathology with high genetic predisposition, and is associated with reproductive health disorders in women. The purpose of the study was to investigate the presence of HLA-DQ2.5 (HLA-DQA1 * 05:01 HLA-DQB1 * 02) and HLA-DQ8 (HLA-DQB1 *03:02) genotypes of predisposition to CD in women with recurrent pregnancy loss. Methods. PCR-SSP (polymerase chain reaction with sequence-specific primers). Results. The increased risk of recurrent pregnancy loss in women is associated with DQ2.5 - the pre-disposition genotype for CD (c2=4.35, P<0,05). Calculation of odds ratio (OR) showed more than 4-fold increase in recurrent pregnancy loss risk in women with HLA-DQ2.5 genotype. Conclusions. The study of HLA markers of celiac disease in women with reproductive loss is important for the purpose of preconceptional prevention of recurrent pregnancy loss. Keywords: celiac disease, recurrent pregnancy loss, HLA markers.

Background: The aim of the present study is to determine role of hysteroscopy in women presented with primary or secondary infertility and in women presented with recurrent pregnancy loss.Methods: This cross-sectional study was conducted at Obstetrics and Genecology Department, Women Health Hospital Assiut University, Egypt from October 2016 to February 2018. Reproductive aged women who are suspected as having intrauterine pathology, such as submucosal myoma, endometrial polyps or other endometrial pathological findings based on the transvaginal ultrasound were enrolled. All patients were scheduled for office hysteroscopy as an outpatient. An informed consent was obtained prior to participation in the study.Results: Hysteroscopy was performed in 139 infertile women and 41 cases of repeated pregnancy loss. With regard to infertile patients; 67.6% of the patients had normal findings, 10.1% of the patients had intrauterine adhesion, 8.6% of the patients had intrauterine polyp. 5.8% of the patients had septate uterus and 3.6% of the patients had depressed fundus. With regard to patients with recurrent pregnancy loss; 51.2% of the patients had normal findings, 21.9% of the patients had partial septum, 9.8% of patients had intrauterine adhesions, 7.3% of patients had intrauterine polyp and 4.9% of the patients had submucous myoma.Conclusions: It was concluded that hysteroscopy should be considered as routine investigation in evaluation of women with primary and secondary infertility.

SummaryThe presence of lupus anticoagulant (LA) predisposes to fetal loss and to venous and arterial thrombosis; however, a subgroup of women is unaffected by pregnancy loss. Currently, no predictive markers are available for the identification of women positive for LA at increased risk for pregnancy loss. It was the aim of our study to investigate whether increased anti-β2-GPI-antibodies predict pregnancy loss in women positive for LA. We performed a cross-sectional study in a cohort of 39 women with persistent LA, who had in total 111 pregnancies. Fifteen women had exclusively normal pregnancies (30 pregnancies) and 24 women had pregnancy losses (81 pregnancies). Anti-β2-GPI-antibodies were determined using a semiquantitative enzyme linked immunoassay (QUANTA Lite™ β2 GPI IgG and IgM; Inova Diagnostics). Increased levels of anti-β2-GPI antibodies were significantly associated with pregnancy loss [odds ratio (OR) 9.6, 95% confidence interval (CI) 1.6 – 56.4].This risk was even higher in the subgroup of women (n=16) with more than two miscarriages or fetal loss after the first trimester [OR 13.1, 95% CI 1.4 – 126.3]. There was no significant association between anticardiolipin antibodies and pregnancy loss [OR 3.5, 95% CI 0.7 – 17.6].The coexistence of anti-β2-GPI and anticardiolipin antibodies was also predictive for pregnancy loss [OR 6.1, 95%CI 1.3 – 29.7]. Interestingly, the prevalence of thrombosis was similar between women with normal pregnancy (87%) and those with pregnancy loss (75%). We conclude that increased levels of anti-β2-GPI antibodies are predictive for pregnancy loss among women positive for LA, and that prophylactic treatment should be considered in these women even without a history of previous pregnancy loss.
