RESUMO

BACKGROUND: Polycystic ovary syndrome is a common multifactorial endocrinopathy disorder affecting 5-15% of reproductive women worldwide. The CYP19 gene encodes key enzyme aromatase involved in androgen-to-estrogen conversion which plays a crucial role in the pathophysiology of the syndrome. Very few studies have been done in the Indian population; hence, we investigated whether CYP19 gene rs2414096 SNP is associated with PCOS and hyperandrogenism susceptibility in Karnataka women. METHODS: Three-hundred subjects including 150 PCOS and 150 age-matched controls were involved in the current case-control study. Sex hormones and biochemical estimation were performed by ELISA. Sanger sequencing and PCR-RFLP were used to genotype the SNP rs2414096. Genotypic-phenotypic association was studied. Statistical analysis was performed. RESULTS: The GG genotype was more common in patients, while the GA genotype was more common in control women. LH/FSH was significantly increased in GG genotype in PCOS when compared with AA and GA genotypes. Variations of CYP19 rs2414096 were not statistically significant with PCOS. CONCLUSION: CYP19 rs2414096 polymorphism was not associated with PCOS; however, the homozygous wild GG genotype may exhibit reduced aromatase activity with subsequent hyperandrogenism implicating endocrine abnormalities.

RESUMO

OBJECTIVE: The study assessed the developmental potential of germinal vesicle (GV) oocytes subjected to in vitro maturation (IVM) after prematuration culture with cilostamide (a phosphodiesterase-3 inhibitor) and the impact of cilostamide exposure on the morphology of meiosis II (MII) oocytes and subsequent embryo quality. METHODS: In total, 994 oocytes were collected from 63 patients. Among 307 GV oocytes, 140 oocytes were selected for the experimental group and 130 oocytes for the control group. The denuded GV-stage oocytes were cultured for 6 hours with cilostamide in the experimental group and without cilostamide in the control group. After 6 hours, the oocytes in the experimental group were washed and transferred to fresh IVM medium. The maturational status of the oocytes in both groups was examined at 26, 36, and 48 hours. Fertilization was assessed at 18 hours post-intracytoplasmic sperm injection. Embryo quality was assessed on days 3 and 5. RESULTS: In total, 92.1% of the oocytes remained in the GV stage, while 6.4% converted to the MI stage (p<0.01) after cilostamide exposure. In both groups, more MII oocytes were observed at 36 hours (25.8% vs. 21.5%) than at 26 hours (10.8% vs. 14.6%) and 48 hours (13% vs. 7.9%) (p>0.05). With the advent of cilostamide, blastocyst quality was better in the experimental group than in the control group (p<0.05). CONCLUSION: Cilostamide effectively blocked nuclear maturation and promoted cytoplasmic growth. Prematuration culture with cilostamide enabled synchronization between cytoplasmic and nuclear maturity, resulting in better blastocyst outcomes.

RESUMO

Many recent studies have evaluated the relation between periodontitis and pregnancy complications. This study aimed to examine the association between preeclampsia and periodontitis in Indian women. A total of 130 pregnant women were enrolled between 26-32 weeks of gestation. Oral health examinations were performed at recruitment and again within 48 hours of delivery to determine the presence and/or progression of periodontitis in all subjects. Pocket depth, clinical attachment loss (CAL), and gingival index were measured in all subjects. There was significant (p < 0.05) difference between the preeclampsia and normotensive groups in the distribution of periodontitis both at recruitment and after delivery. Multiple logistic regression demonstrated that periodontitis both at enrolment (OR = 5.78, 95% CI 2.41-13.89) as well as within 48 hours of delivery (OR = 20.15, 95% CI 4.55-89.29), may be associated with an increased risk of preeclampsia.

RESUMO

Background and Objectives: Preeclampsia is a challenging disease of human pregnancy that affects the mother and her foetus. It is a common obstetric syndrome of undefined aetiology affecting 7-10% of pregnant women. This study aimed to investigate the total antioxidant capacity (TAC), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities, malondialdehyde levels, uric acid, vitamin C, and vitamin E levels in serum and saliva of preeclamptic and normotensive pregnant women with and without periodontitis. Methods: Sixty pregnant women, divided into four groups, preeclamptic women with and without periodontitis, and normotensive pregnant women with and without periodontitis, were recruited between 26 and 36 weeks of gestation from the Outpatient Department of Obstetrics and Gynaecology, KS Hedge Hospital, Mangalore. Pocket depth, clinical attachment loss, and gingival index were measured in all subjects. Saliva and serum levels of TAC, SOD, and GPx activities, malondialdehyde levels, vitamin C, vitamin E, uric acid were determined using spectrophotometer. Results: Comparison of sociodemographic variables among the study groups showed no significant differences. Salivary malondialdehyde levels were highest (p = 0.025), levels of antioxidants vitamin C (p = 0.027) and uric acid (p = 0.013) being significantly lower in preeclamptic women with periodontitis. This group also had significantly lower serum levels of vitamin C (p = 0.041) and SOD (p = 0.004). Conclusions: The results of our study show that periodontal disease may be potential risk factor for severity, progression, and even initiation of preeclampsia because of reduced antioxidant capacity or increased oxidative stress.

RESUMO

BACKGROUND: Pre-eclampsia is one of the major causes of maternal and fetal morbidity and mortality. Though the aetiology is obscure, recent studies indicate that serum levels of calcium and magnesium may have a role in pre-eclampsia. AIM: The aim of this study was to find out the relationship of serum levels of calcium and magnesium in pre-eclamptic pregnancies compared to normal pregnancies in women from southern coastal India. SETTINGS AND DESIGN: This study was done in a medical college hospital in southern coastal India. MATERIALS AND METHODS: The blood samples from 60 pre-eclamptic women and an equal number of controls were analysed for calcium and magnesium levels. Data on Body Mass Index, maternal and gestational ages, serum calcium and magnesium were compared between the two groups. Outcome of pregnancy was analysed in both the groups and compared. STATISTICAL ANALYSIS: Data was expressed as Mean ± Standard Deviation. Data analysis was done by SPSS version 20. Comparison of serum levels of the elements between the two groups was performed by Independent t-test and Chi-square test and P-value of < 0.05 was considered as statistically significant. RESULTS: The serum calcium concentration was significantly lower in the pre-eclamptic group compared to normotensives (7.84 ± 0.87 mg/dl Vs 8.97± 0.69 mg/dl, p<0.001) whereas the levels of serum magnesium showed a marginal difference in both the groups. (1.43± 0.55 mg/dl Vs, 1.57 ± 0.72 mg/dl P 0.257) The study also showed that pre-eclamptic women were older, their BMI was higher and birth weight of babies lower compared to normotensives. CONCLUSION: According to the results of our research, intake of supplements, mainly calcium may help in the reduction of incidence of pre-eclampsia especially in a population of a developing country like ours where the nutrition is poor. Not many studies have been done in developing countries to assess the role of these elements in pre-eclampsia. The actual role of magnesium and calcium supplements needs further investigation.

RESUMO

Gonadoblastoma is a rare gonadal tumour consisting of a mixture of germ cells and sex cord stromal derivatives resembling immature granulosa and Sertoli cells. It usually arises in various types of gonadal dysgenesis containing Y chromosome like pure or mixed gonadal dysgenesis. Occurrence in phenotypically and chromosomally normal women is very rare. We report here a case of gonadoblastoma with dysgerminoma in a 14-years-old girl who presented with a huge tumour, virilisation and normal 46XX karyotype. Association of dysgerminoma is seen in 50% cases of gonadoblastomas. Elevated tumour markers like hCG and alpha Fetoprotein may make the diagnosis challenging.
