Is there an effect of thyroid autoimmunity on the outcomes of assisted reproduction?

We aimed to evaluate the role of thyroid autoantibodies (TAA) on the outcomes of intracytoplasmic sperm injection-embryo transfer (ICSI-ET). A prospective case-control study was conducted in the in vitro fertilisation (IVF) centre of Suleymaniye Maternity Training and Research Hospital, Istanbul, Turkey between July 2013 and March 2014. A total of 49 (19.52%) TAA-positive and 202 TAA-negative patients were enrolled. Demographic characteristics and laboratory parameters were recorded. All patients underwent ICSI-ET. Thirty-one TAA-positive patients (32 cycles) and 121 TAA-negative patients (126 cycles) completed the study. Mean female age, body mass index (BMI), type of infertility, duration of infertility, antral follicle count (AFC), anti-Müllerian hormone (AMH), basal follicle stimulating hormone (bFSH), luteinising hormone (bLH), and oestradiol (bE2), prolactin and thyroid hormone profiles, male age and aetiology of infertility of both groups were similar (p > 0.05). There was no significant difference between groups in terms of duration and dose of gonadotropin (Gn) therapy, day of human chorionic Gn (hCG) administration, serum E2 and progesterone levels, number of collected oocytes, ratio of fertilisation, number of available embryos, positive pregnancy test, biochemical pregnancy, clinical pregnancy, ratio of miscarriage and ongoing pregnancy (p > 0.05). In conclusion, we failed to demonstrate a significant role of TAA on the outcomes of ICSI-ET in euthyroid patients. Further studies with larger numbers of participants are required to clarify these data.

The effect of Ramadan fasting and maternal hypoalbuminaemia on neonatal anthropometric parameters and placental weight.

In Islamic religion, daytime fasting during the month called Ramadan is an annual practice. In this study, we aimed to investigate the effect of Ramadan fasting and maternal hypoalbuminaemia on neonatal growth parameters. A prospective case-control study was conducted in Diyarbakir and Istanbul, Turkey. The sample size of fasting group was 168 and that of non-fasting group was 170. Demographic characteristics, obstetrics ultrasonographic findings and laboratory parameters of the participants were recorded. Neonatal anthropometric parameters and placental weight were noted. The mean placental weight was significantly higher in the fasting group (p = 0.037). Also, in the fasting group, pregnant women with hypoalbuminaemia had significantly higher placental weight (p = 0.009). In conclusion, the mean placental weight in the fasting group was significantly higher. Also a significant correlation between placental weight and maternal serum albumin level was observed in the fasting group.

Noninvasive assessment of subclinical atherosclerosis in normotensive gravidae with gestational diabetes.

AIM: Carotid artery intima-media thickness (CIMT), hyperhomocysteinemia, microalbuminuria, and nitric oxide reflect subclinical atherosclerosis and predict the risk of future cardiovascular events. We aimed to evaluate the presence of subclinical atherosclerosis and endothelial dysfunction in normotensive patients with gestational diabetes mellitus (GDM) noninvasively. PATIENTS AND METHODS: We enrolled 41 normotensive patients with GDM and 44 healthy gravidae in the study. Serum homocysteine and nitric oxide levels, urinary albumin excretion (microalbuminuria), and CIMT were evaluated along with lipid parameters and anthropometric measurements. RESULTS: Patients with GDM had significantly higher levels of serum homocysteine, urinary albumin excretion, and increased CIMT (p < 0.001, p=0.005, and p < 0.001, respectively). Nitric oxide levels were significantly reduced in the patient group (p < 0.001). There was a significant difference between groups in terms of low-density lipoprotein (LDL) but not of high-density lipoprotein (HDL) and triglyceride levels. A significant correlation was observed between CIMT and serum LDL, HDL, homocysteine, nitric oxide levels, and urinary albumin excretion. Microalbuminuria was significantly correlated with serum homocysteine levels (p=0.03) but not with nitric oxide. CONCLUSION: Independent of elevated blood pressure, subclinical atherosclerosis and endothelial dysfunction exist in normotensive patients with GDM. Further studies with a large number of participants are required to clarify these data.

Chromosome heteromorphisms are more frequent in couples with recurrent abortions.

Chromosomal heteromorphism is considered a variant of a normal karyotype, but it is more frequent in couples with repeated miscarriages. We investigated chromosomal heteromorphism in couples with repeated miscarriages in comparison with a control group. A total of 455 couples who applied to our genetic diagnosis laboratory in Diyarbakir, Turkey, were evaluated for chromosome heteromorphisms; 221 of these couples (the study group) had recurrent abortions and 234 of them (the control group) had no history of abortions and had at least one living child. The patient group of couples with recurrent abortions were found to have a significantly higher rate of chromosome heteromorphism (8.4%) in comparison with the control group (4.9%). When the patients were evaluated according to gender, males had a significantly higher rate of chromosome heteromorphism (11.3%) than females (5.4%). We conclude that since couples with recurrent abortion and males have higher rate of chromosome heteromorphism, cases of heteromorphism should not be disregarded in the etiological investigation of recurrent abortions. Further research should be done to investigate the phenotypic effects of chromosome heteromorphism.

Tubo-ovarian abscess presenting as an ovarian tumor in a virginal adolescent: a case report.

Tubo-ovarian abscess (TOA), a serious complication of pelvic inflammatory disease, unites the fallopian tube and ovary and, is rarely observed in sexually inactive adolescent girls. A pelvic mass, supposedly originating from the ovary, was detected in a 13-year-old sexually inactive girl suffering from abdominal pain and menstrual disorder. Pelvic ultrasonography pointed out a semisolid, hyperechogenic mass of 57x73 mm in the left adnexal area. Laparotomy revealed an unilateral TOA adhering to the bowel and omentum. Abscess drainage and adhesiolysis were performed and postoperative antibiotherapy was administered. TOA should be considered in the differential diagnosis of females with abdominal pain and adnexal mass whether sexual activity is present or not.

Evaluation of clinical and cytogenetic findings on 1,068 second-trimester amniocenteses in Southeast Turkey.

OBJECTIVE: To investigate the indications of amniocentesis for the detection of chromosomal abnormalities among a sample of patients in Southeast Turkey. MATERIAL AND METHODS: Between 2004 and 2007, 1,068 second-trimester amniocentesis tests were performed in the Medical Biology and Genetics Department Laboratory at Dicle University. Amniotic fluids were cultured by using long-term tissue culture for prenatal diagnosis with cytogenetic analysis. The clinical and cytogenetic findings on 1,068 second-trimester amniocenteses were analyzed. The indications, the proportions of karyotypes according to indications and complications were summarized. RESULTS: Among the 1,068 amniocentesis cases, the maternal age between 35 and 39 years was the most common age group (34.5%). Of the clinical indications abnormal maternal serum screening results were the most common indication for amniocentesis (37.6%). Of 52 cases (4.9%) with detected chromosomal aberrations, 39 were numeric (27 trisomies, 10 sex chromosome aberrations and two triploidies) and 13 were structural (2 reciprocal translocations, 2 Robertsonian translocations and 6 inversions). The highest detection rate of chromosome aberrations was in cases undergoing amniocentesis for abnormal maternal serum screening combined with abnormal ultrasound (US) findings (8.0%). CONCLUSION: This study suggests that complementary measures, such as routine antenatal US and maternal serum screening, should be added to increase the efficiency of genetic amniocentesis. Therefore, the study could be used for the establishment of a database for genetic counseling.
