The aim of this work was to study the expression of the cytokines IFN-γ, IL-4, IL-17 A, and TGF-β1 in peripheral blood and follicular fluid (FF) of patients positive for antithyroid autoantibodies (ATA+ ) with normal thyroid gland function and the influence of these autoantibodies on in vitro fertilization and embryo transfer (IVF-ET) pregnancy outcomes. Nineteen patients were in the ATA+ group, and 27 patients tested negative for anti-thyroid autoantibody (ATA- ). Blood samples were drawn from the two groups of patients on the oocyte retrieval day and the 5th and 14th days of transplantation; in addition, FF was extracted on the oocyte retrieval day from both groups of patients and tested through enzyme-linked immunosorbent assay (ELISA) for IFN-γ, IL-4, IL-17 A, and TGF-β1...

Herbal supplements are widely used during pregnancy, although there are insufficient data regarding their efficacy and safety. Some of them have been associated with hypertension, including licorice, which induces the so called mineralocorticoid-excess syndrome, a clinical picture resembling to pseudohyperaldosteronism. This action is mediated via inhibition of 11-hydroxysteroid dehydrogenase type 2 (11-HSD2), leading to impaired inactivation of cortisol to cortisone, accumulation of cortisol, and finally to excessive mineralocorticoid activity, especially in the distal and cumulative tubule of kidneys...

The aim of the study was to evaluate whether ovarian reserve depends on chronic kidney disease. Twenty-four patients, 23-45 years with chronic kidney disease (CKD) stages 3-4 were included in the study. All the patients underwent transvaginal ultrasounds to assess antral follicle count (AFC) and ovarian volume. The serum samples were obtained on days 3-5 of the menstrual cycle from all participants for anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH), and estradiol (E2) levels. On the base of the study, it was concluded that the most sensitive parameters of ovarian reserve are AMH and AFC...

Women during perimenopausal period experience a range of symptoms, which interfere with physical, sexual, and social life. About 65-75% of symptoms connected with postmenopausal period are vasomotor symptoms (VMS), such as hot flushes and night sweats. Hot flushes are subjective sensation of heat associated with cutaneous vasodilatation and drop in core temperature. It is suspected that VMS are strongly correlated with pulsatile oversecretion of gonadotropin-releasing hormone (GnRH) and subsequently luteinizing hormone (LH)...

Pheochromocytoma (PH) is a tumor that arises from chromaffin cells of the adrenal medulla. Though being this benign neoplasm very rare in pregnancies, lack of treatment nevertheless causes high mortality rates for both the mother and the fetus. Classic symptoms related to PH are hypertension, abdominal pain, diaphoresis, and headache; but it can be easily misdiagnosed as gestational hypertension or preeclampsia. Its appearance is sporadic, but there are some genetic disorders that favor its onset (e.g. MEN 2A and 2B)...

Circulating estrogens fluctuate during the menstrual cycle but it is not known whether this fluctuation is related to local hormone levels in adipose tissue. We analyzed estrogen concentrations and gene expression of estrogen-regulating enzymes in breast subcutaneous adipose tissue in premenopausal women with (n = 11) and without (n = 17) estrogen receptor-positive breast cancer. Estrone (E1 ) was the predominant estrogen in premenopausal breast adipose tissue, and E1 and mRNA expression of CYP19A1 in adipose tissue correlated positively with BMI...

Obesity in pregnant women has been associated with an increased risk of maternal complications, including gestational diabetes mellitus (GDM), a process that is related to oxidative stress (OS). To evaluate the biomarkers of OS in red blood cells (RBCs), we assigned 80 pregnant women to one of three groups: control (n = 28), overweight (n = 26) and obese (n = 26). Then, we measured in plasma, the levels of glucose, triacylglycerol (TAG), insulin, free fatty acids (FFAs), leptin and cytokines (e...

Tissue-selective estrogen complex (TSEC) is projected as a progestogen-free option for the treatment of estrogen deficiency symptoms in postmenopausal, non-hysterectomized women. TSEC combines the benefits of estrogen with a selective estrogen receptor modulator (SERM), in this case bazedoxifene acetate (BZA), which has an antagonistic effect on the endometrium, thus avoiding the use of progestins. The authorized TSEC combination (conjugated estrogens [CE] 0.45 mg/BZA 20 mg) for the alleviation of vasomotor symptoms has been demonstrated in randomized clinical trials compared with placebo or menopausal hormone therapy (MHT)...

Hypertriglyceridemia is the third most common cause of acute pancreatitis. Among the causes that lead to secondary hypertriglyceridemia, the use of contraceptive agents is the main reason to be assessed in young women. We report a case of a 31-year-old woman who had suffered two acute pancreatitis episodes secondary to hypertriglyceridemia. In the investigation, the previous medical team indicated a genetic screening before ruling out all secondary causes. LPL, apo CII and apo AV genes were negative for mutations...
