Infertility is one of the most common diseases of the reproductive system, which carries a significant medical and social burden, affecting from 10 to 15% of married couples, and one of the causes of which is polycystic ovarian syndrome (PCOS), associated with menstrual and endocrine disorders. Changes in the concentration of key enzymes of the metabolic pathway of vitamin D in PCOS may affect the regulation of local tissue homeostasis. Mechanisms of inhibition of cell proliferation under the action of vitamin D have not been fully explored. The aim of the study is to investigate the expression of VDR and hormone receptors in the ovaries of women with PCOS. Material and methods. Patients were divided into main (I) and control groups (II), that included women (n=60) aged 18 to 44 years (mean age - 29.1±3.3 years), who at diagnostic laparoscopy due to infertility of unknown cause. Immunohistochemical (IHC) study of ovarian cysts was performed according to a standard protocol using antibodies to VDR, AR, ERß, PR. The expression of VRD, 1α-OH, 24-OH in samples of ovarian cysts was determined by polymerase chain reaction in real time (PCR-RT). Results. The following IHC expression of the studied markers was observed in the samples of the 1st group cysts of women with PCOS: VDR - 67.7±2.1%; AR - 51.7±1.3%; ERß - 23.1±1.2%; PR - 89.3±2.1%. According to PCR-RT data, the relative VDR expression in group I was 4,31±0,18 arb. u., vs 2,17±0,11 arb. u. in the control group. Conclusions. The key role in PCOS pathogenesis is played by complex metabolism disorder of vitamin D and androgen-estrogen balance as well as decrease of ERß and increase of PR expression level.

The proportion of patients with multiple unsuccessful attempts of assisted reproductive technology (ART) is about 30% of all patients treated with the use of ART. Women with history of unsuccessful ART attempts - a special category of patients who require emergency attention and a thorough examination at the stage of preparation for superovulation stimulation,the selection of embryos and endometrium preparation for embryo transfer. The objective: to distinguish high-risk group of unsuccessful attempts based on a detailed analysis of anamnestic and clinical data of infertile women with repeated unsuccessful ART attempts that requires more in-depth study of hormonal features, ovarian reserve and condition of the endometrium. Materials and methods. For better understanding of the problem of repeated unsuccessful ART attempts and сreation of efficient infertility treatment algorithms for these couples we conducted a thorough analysis of anamnestic data of three groups of infertile women (105 patients), which were distributed by age: group I – younger than 35, the II group – from 35 to 40, the III group - over 40 years. These groups of patients were compared with each other and with the control group of healthy women (30 persons). Results. Leading stress factors in the percentage three times prevailed in the group of infertile women and had a direct connection with the fact of procedure «fertilization in vitro» and chronic stressors caused by prolonged infertility. Primary infertility was observed significantly more frequent in patients younger than 35 years (p <0.05), secondary infertility - mostly in the second and third experimental groups (p <0.05). Noteworthy significant percentage of wellknown causes of infertility and idiopathic factor in all groups, and the prevalence of tubal-peritoneal factor in the second and third experimental groups, and endocrine dysfunction in the I experimental group. The most common disorder among this category of woman was polycystic ovary syndrome. Frequency of usual miscarriage among patients of I ana II groups was two times higher than in the third group (p <0.05). Among the experimental groups the leading place belongs urinary tract infection, respiratory tract diseases, pathologies of the cardiovascular system. Data of the stratified analysis show an increase likelihood of repeated unsuccessful ART attempts under the influence of constant chronic stress (odds ratio OR=2.06; 95% CI: 0.95–3.17; p<0.05). Conclusions. Among infertile patients with repeated unsuccessful ART attempts must be separated a high risk group of failures. The identity depends on the duration of infertility, female age and leading combination of factors. Key words: repeated unsuccessful ART attempts, anamnesis, infertility, high risk.

Background: Shear wave electrography (SWE) is a novel non-invasive imaging technique which demonstrate tissue elasticity. Recent research evaluating the elasticity properties of normal and pathological tissues emphasize the diagnostic importance of this technique. Aims: Polycystic ovarian syndrome (PCOS), which is characterized by menstrual irregularity, hyperandrogenism, and polycystic overgrowth, may cause infertility. The aim of this study was to evaluate the elasticity of ovaries in patients with PCOS using SWE. Methods: 66 patients diagnosed with PCOS according to the Rotterdam criteria (PCOS = group I) and 72 patients with non-PCOS (Control = group II), were included in the study. Demographic and clinical characteristics of the participants were recorded. Ovarian elasticity was assessed in all patients with SWE, and speed values were obtained from the ovaries. The elasticity of the ovaries was compared between the two groups. Results: While there were statistically significant differences between the groups in body mass index (BMI), right and left ovarian volumes, luteinizing hormone and testosterone levels (p<0.05), no significant differences were found between groups I and II in the velocity (for the right ovary 3.89±1.81 vs. 2.93±0.72, p=0.301; for the left ovary 2.88±0.65 vs. 2.95±0.80, p=0.577) and elastography (for the right ovary 36.62±17.78 vs. 36.79±14.32, p=0.3952; for the left ovary 36.56±14.15 vs. 36.26±15.10, p=0.903) values, respectively. Conclusion: We could not obtain different velocity and elastography values from the ovaries of the patients with PCOS using SWE. Therefore, further large-scale studies are needed to elucidate this issue.

Abstract Background Autism is a group of neurodevelopmental disabilities with various genetic and environmental risk factors. Vitamin D is an important neurosteroid hormone which can affect brain development and function, but research on its use in treating autism has been limited. Objectives The current study aimed at assessing the level of 25 OH vit D3level in a group of autistic infants and children compared to controls and correlating it with the severity of autistic manifestations and evaluation of the role of therapeutic doses of vitamin D on the severity of autistic manifestations. Methodology Thirty autistic Egyptian children (group I) and 30 clinically healthy age and sex matched controls were enrolled (group II). Therapeutic doses of vitamin D were given for autistic children who showed insufficient levels of 25 OH cholecalceferol for a period of 4-6 weeks followed by maintenance doses for another 6 weeks. Psychometric and laboratory evaluation for this group was done thrice: at the onset of study, at 6 week after enrollment in the study, and at 12 weeks after that enrollment. Results Serum vitamin D level was substantially reduced in patients with ASD in comparison to control group, and on the other hand, 25 (OH) vitamin D level was significantly negatively correlated with ATEC score and Total CARS score. Autistic children who received vitamin D3 treatment had significant improvement of CARS and ATEC scores. Conclusion vitamin D supplementation significantly improved the outcome of enrolled autistic children. It is recommended to follow up our studied sample to check the consolidation of improvement for how long it will be needed.

AbstractThe objective of the study was to measure the levels of 25-hydroxyvitamin D [25(OH)D] and vitamin D binding protein (VDBP) and assess their relationships with cardiovascular risk factors in women with the polycystic ovary syndrome (PCOS). A group of 267 women, aged 20–35 years (24.7 ± 4.9): 167 with PCOS and 100 healthy women were divided according to body mass index. Biochemical and hormonal parameters were measured. Free and bioavailable 25(OH)D were calculated using the mathematical equations. The percentage of body fat and visceral fat deposit were assessed by DXA. In the normal weight control group total, free, bioavailable 25(OH)D (p<0.001 for all) were significantly higher than in its overweight/obese counterpart, while VDBP levels were comparable. In PCOS women total 25(OH)D (p<0.001), and VDBP (p –0.006) were lower in the overweight/obese subgroups than in the normal weight ones. In both groups serum VDBP levels correlated negatively with serum insulin and positively with sex hormone binding globulin. In PCOS group, in contrast to control group, VDPB was negatively correlated with abdominal fat deposit, BMI, fasting glucose and positively with HDL. Despite lower total 25(OH)D in obese PCOS women, all women with PCOS (lean and obese) had comparable free and bioavailable 25(OH)D, which might be a result of concomitantly lowered serum VDBP levels in obese PCOS women. VDBP might play important role in the regulation of availability of active fractions of 25(OH)D in PCOS women. VDBP seems to be associated with cardiovascular risk factors such as BMI, waist circumference, visceral fat, and fasting serum insulin in women with PCOS.

The pleiotropic effects of vitamin D (VD), whose active form is synthesized in the kidneys, play a certain role both in forming and functioning the feto-placental system, including various pregnancy complications. The aim of the study was to evaluate the vitamin D status in pregnant women with placental dysfunction (PD) and chronic inflammatory kidney disease (CIKD). During 24–34 pregnancy weeks, 56 pregnant women with PD were examined (main group ‒ I); 24 patients (42.85 %) had chronic pyelonephritis (group IA). The control group (group II) had 31 conditionally healthy pregnant women. The total VD level in the blood was determined by ELISA; in addition to the general clinical standard examination, the urine also underwent bacteriological examination. The VD mean level in pregnant women with PD and CIKD was significantly lower than that in the control group (31.08 ± 7.2 and 45.42 ± 9.67 ng/ml (p <0.01)). Only 33.33 % of pregnant women in group IA had a VD optimum, as well as 93.55 % (p < 0.01) in the control group and 17.86 % in group I. 8.33 % of pregnant women had a VD deficiency in group IA (RR = 2.09; CI 95 % ‒ 1.8‒2.42). The patients with a VD-deficiency were absent in the control group. 58.33 % of women in group ІА had a suboptimal VD level and 6.45% in the control group (RR = 3.57; CI 95 % ‒ 1.62‒7.88). Bacteriuria was observed in all pregnant women with a VD-deficient or suboptimal level. At the optimum VD level, bacteriuria was diagnosed twice less (χ2 = 66.67; p <0.01). In patients with an inadequate VD level, CIKD was diagnosed 3.8 times more (RR = 3.57; CI 95 % ‒ 1.62‒7.88). 494 Proceedings of the National Academy of Sciences of Belarus. Medical series, 2020, vol. 17, no. 4, pp. 493–499 A significantly calcitriol reduction in pregnant women with placental dysfunction suggests that the deficiency or the suboptimal level of vitamin D and inflammatory kidney diseases may be the interdependent processes that play a decisive role in the formation of placental dysfunction.

There are considerable public concerns about the relationship between mobile phone radiation and human health. The present study assesses the effect of electromagnetic field (EMF) emitted from a mobile phone on the immune system in rats and the possible protective role of vitamin D. Rats were randomly divided into six groups: Group I: control group; Group II: received vitamin D (1000 IU/kg/day) orally; Group III: exposed to EMF 1 h/day; Group IV: exposed to EMF 2 h/day; Group V: exposed to EMF 1 h/day and received vitamin D (1000 IU/kg/day); Group VI: exposed to EMF 2 h/day and received vitamin D (1000 IU/kg/day). After 30 days of exposure time, 1 h/day EMF exposure resulted in significant decrease in immunoglobulin levels (IgA, IgE, IgM, and IgG); total leukocyte, lymphocyte, eosinophil and basophil counts; and a significant increase in neutrophil and monocyte counts. These changes were more increased in the group exposed to 2 h/day EMF. Vitamin D supplementation in EMF-exposed rats reversed these results when compared with EMF-exposed groups. In contrast, 7, 14, and 21 days of EMF exposure produced nonsignificant differences in these parameters among all experimental groups. We concluded that exposure to mobile phone radiation compromises the immune system of rats, and vitamin D appears to have a protective effect.

Objective. To investigate the possible association of calcium and vitamin D deficiency with hypoadiponectinemia in women with PCOS. Subjects and Methods. In this case-control study, 103 PCOS cases and 103 controls included. The concentrations of calcium, 25-OH-vitamin D (25OHD), adiponectin, insulin, glucose, total cholesterol, HDL-cholesterol, triglyceride (TG), and androgens were measured in fasting blood samples. Results. Adiponectin (8.4±2.7 ng/mL versus 13.6±5 ng/mL in control group, P:0.00), calcium (2±0.1 mmol/L versus 2.55±0.17 mmol/L in controls, P:0.00), and 25-OH-Vit D (30±2.99 nmol/L versus 43.7±5.2 nmol/L in control group, P:0.00) levels were decreased in women with PCOS. Subjects with PCOS had higher concentrations of TG (1.4±0.77 mmol/L versus 1.18±0.75 mmol/L in control group, P:  0.019) and dehydroepiandrosterone sulfate (DHEA-S) (10.7±11 mmol/L versus 9.7±10.4, P:0.02 in control group). There were significant correlations between adiponectin concentrations with calcium (r:0.78, P:0.00) and 25OHD levels (r:0.82, P:0.00). The association of hypoadiponectinemia and PCOS was not significant considering 25OHD as a confounding factor. Conclusion. The present findings indicate that the association of hypoadiponectinemia with PCOS is dependent on vitamin D. A possible beneficiary effect of vitamin D on the metabolic parameters in PCOS may be suggested.

Purpose: To determine the levels of Vitamin D in children with myopia and to compare them with age matched controls. Study Design:  Case control study. Place and Duration of Study:  The study was conducted in Naseer Memorial Hospital, Dadhyal Azad Kashmir from March 2016 to March 2017. Material and Methods:  Two hundred patients were selected using convenient sampling technique and were divided two groups (group I Myopic and group II control). Myopia was labeled if after subjective refraction a Spherical Equivalent (SE) of −0.50 diopters (D) or more was found. Vitamin D levels were measured by radioimmunoassay technique with Diasorin SR® kit following the user’s manual. Vitamin D levels less than 20 ng/ml were considered Vitamin D deficient following the standards of American academy of pediatrics. The collected data was entered in the statistical package for social sciences (SPSS) version 21 for analysis. Independent t–test was used to determine the significant difference of means between controls and patients. P-values less than 0.05 were considered significant. Results:  Mean age of controls and myopes were 10.65 ± 3.9 and 10.20 ± 2.5 years respectively. Vitamin D levels in myopic children were found to be 14.95 ± 3.75 ng/ml and there was no significant difference in mean values of Vitamin D levels in myopic and control group. Conclusion:  We found no difference in Vitamin D levels of myopic and non myopic children and concluded that Vitamin D has no role in development or progression of myopia.

Background: We aimed to explore the clinical efficacy of vitamin D combined with metformin and clomiphene in the treatment of patients with polycystic ovary syndrome combined with infertility. Methods: Overall, 396 cases of polycystic ovarian syndrome combined with infertility in Yantai Yuhuangding Hospital, Yantai, China were prospectively analyzed. Among them, 204 cases treated with vitamin D combined with metformin and clomiphene were set as the study group; 192 cases treated with only metformin and clomiphene were set as the control group. The ovarian volume and thickness of uterine wall before and after treatment were recorded. Levels of fasting insulin (FINS), luteinizing hormone (LH), testosterone (T), folliclestimulating hormone (FSH), and estradiol (E2) before and after treatment were recorded. Results: There was no difference in body weight, BMI, ovarian volume, thickness of ovarian wall, FINS, LH, T, FSH and E2 between the study group and the control group; there was no significant difference in FSH, E2 and the thickness of uterine wall between the two groups. After treatment, the BMI, FINS, LH, and T in the study group were significantly lower than those in the control group (P<0.05); the incidence rates of oligomenorrhea, facial acne and hairy symptoms in the study group were significantly lower than those in the control group (P<0.05); after treatment, the ovulation rate and pregnancy rate in 36 cycles in the observation group were significantly higher than those of the control group (P<0.05). Conclusion: Our challenge could significantly improve clinical symptoms and endocrine conditions, and greatly enhance the ovulation rate and pregnancy rate.
