ACTA ENDOCRINOLOGICA (BUC)

Objective. To find out the relationship of thyroid hormone profile of females with outcomes after intra cytoplasmic sperm injection (ICSI). Method. It was a cross sectional study conducted in Islamabad Clinic Serving Infertile Couple from June 2013 till August 2015. T3 (triiodo thyronine), T4 (thyroxine) and TSH (thyroid stimulating hormone) of 168 consented females was estimated after they underwent the first step of treatment protocol (ovarian down regulation) for ICSI. Pregnant group had ß hCG result more than 25 IU/mL while the rest were included in the non-pregnant group. Both groups were compared by using independent sample t-test. Pearson correlation coefficient was used to associate T3 and T4 with other pregnancy variables with their significance. Results. Non pregnant women had significantly higher mean values for T3 and T4 as compared to pregnant women (p <0.05, p<0.01). Difference in mean TSH value between non-pregnant and pregnant women was not significant p=0.08. It was found that T4 gave significant negative association with grading of embryo-I, blastocysts formed, thickness of endometrium and number of gestational sacs. Conclusion. Disturbance in thyroid profile with raised T4 levels leads to alteration in endometrial thickness and quality of embryos required for implantation and hence conception.

Context. Exercise and anabolic steroids are anticipated to promote fat mass reduction and so to decrease the number of comorbidities related to excessive weight. Objective. The aim of this study was to verify the influence of aerobic exercise and the use of steroids on the accumulation of adipose tissue and on the biochemical limitations of Wistar rats nourished by a hypercaloric diet. Methods. Forty, young male Wistar rats were split into four groups: obese control (n=10), obese under treatment (n=10), obese under aerobic exercise (n=10) and obese under aerobic exercise and treatment (n=10). All animals were fed with a hypercaloric diet and animals under treatment received intramuscular testosterone. Body (weight and visceral fat) and blood (lipidogram, glucose, and liver enzymes) parameters were assessed. Results. The group treated with aerobic exercise and testosterone revealed a reduction in body weight and visceral, perirenal, retroperitoneal and epididymal fats, accompanied by the blood levels of glucose, lactate, LDLcholesterol, HDL-cholesterol, and lactate dehydrogenase; following high-intensity physical activity. Conclusion. The results support the theory that the combination of steroids and physical activity reduces the side-effects of androgenic-anabolic hormones and conveys benefits to some constraints

Context. Ghrelin, in both its acylated and desacylated forms, and leptin can modulate fetal energy balance and development. Objective. The aim of our study is to assess desacylated ghrelin (DAG) and leptin values and influence on intrauterine and postnatal growth in infants with intrauterine growth restriction. Design, subjects and methods. We performed a prospective study on 39 infants recruited over five months, 20 appropriate - for - gestational - age (AGA) infants and 19 small-for-gestational-age (SGA) infants, in which we measured DAG and leptin in the umbilical cord blood and we compared their respective values between the two groups, along with auxological parameters at birth and at 10 months of postnatal age. Results. Our results show that both DAG and leptin have lower values in SGA infants and correlate with most of the anthropometrical parameters at birth. Both hormones correlate with weight at 10 months in SGA infants, but this correlation lacks in AGA infants. Whereas DAG in the cord blood can be considered a predictor for weight at 10 months (β=0.207, p=0.001), the same cannot be stated about leptin (β=0.078, p=0.195). Conclusion. DAG and leptin are involved in both intrauterine and postnatal development, but the extent of their role is still to be determined.

Context. The androgen/androgen receptor interaction plays a critical role in the development of the male genital system, and investigations around these receptors can expand our knowledge about mechanisms of some male abnormalities such as hypospadias. Objective. In the present study, the expression of androgen receptor (AR), fibroblast growth factor-10 (FGF10), and fibroblast growth factor receptor-2 (FGFR2) genes were investigated in prepuce tissue of healthy and hypospadic children. Design. It was a case-control study with follow-up about up to eight months after operation. Subjects and Methods. Patients’ tissue samples (n=20) and controls tissue samples (n=20) were collected after surgery and circumcision. After RNA extraction and cDNA synthesis, the Real time PCR was performed to evaluate and compare the levels of gene expressions. Both groups were checked until eight months after surgery. Results. The results showed that FGFR2 gene expression had significantly decreased in prepuce tissue of patients compared with healthy children (p-value <0.05). Patients and healthy children follow up showed that 20% of hypospadic patients who needed reoperation had AR gene upregulation along with FGF10 and FGFR2 downregulation. Conclusions. Taken together, interestingly, FGF10/ FGFR2 signaling has an important role in external genital system development and wound healing process.

Aims: Prolonged exposure to a glucocorticoid excess leads to cognitive impairment in experimental animals as well as humans. The present study tries to identify the cognitive deficits in patients with Cushing’s syndrome and to evaluate the possible residual deficits in patients after treatment. Materials and methods: 19 patients (women) with a history of chronic endogenous hypercortisolemia were investigated for etiology using clinical and biochemical criteria. Cognitive functions were evaluated using a battery of psychometric tests: the Rey Auditory Verbal Learning Test (RAVLT), the BCR2 battery for general intellectual potential and the Prague test, for divided attention and resistance to psychic fatigue. The patients were divided into two groups (before surgical treatment– Cushing and after surgical treatment – postCushing) without differences in age or duration of studies between groups (p = ns). The controls were considered to belong to the general population for which the psychometric tests were standardized. Results: Both groups showed an altered pattern of incremental learning - scores below standard in the last two trials of the RAVLT (one sample t test, one tailed, p<0.05), and the total score (p<0.05 for PostCushing, p=0.07 for Cushing); both had very low total scores in the battery for intellectual potential. The PostCushing scores were significantly better than those of the Cushing group for only one nonverbal test (complex perceptual analysis), p<0.02. There appears to be no significant effect of cortisol exposure on distributive attention; there is however an alteration in the resistance to psychic fatigue. Daily average cortisol exposure was positively correlated with the number of errors in learning for both groups (r=0.65, p=0.058 for Cushing; r=0.85, p<0.005 for PostCushing) Duration of illness was negatively correlated with the total learning score in the PostCushing group (r=-0.68, p<0.05). For the Cushing group there was a strong negative correlation between the duration of illness, general performance (r=-0.81, p<0.05) and verbal scores (r=-0.77, p<0.07).

There are no new national growth references for the Romanian population and the current recommendations for short stature evaluation is the use of the Swiss growth charts developed based on a longitudinal study. The aim of the present paper is to present the new synthetic growth references for Romanian children. Material and methods. We used local Romanian data from 9 studies with information on height and weight obtained between 1999 and 2016. Based on their plausibility and methodology six studies were selected for generating the National Synthetic Growth References for Romanian Children based on the specific methodology described previously. The selected studies included 8407 subjects measured in schools/kindergartens. Age is reported in years covering a range from 3-18 years. Height and weight were measured at a precision of 0.1 cm and 0.1 kg. All children were measured at normal temperature, in light clothes, without footwear. Results. We present the charts and tables with the common centiles for height, weight and body mass index for boys and girls. Conclusion. We suggest synthetic growth references based upon recent growth data from 6 different Romanian regions as new National Growth Charts for Romanian children.

The subCarpathian areas of Arges county are now characterized by a moderate endemia of iodine deficiency disorders (IDD) due to salt iodization. However, we found some cases of endemic cretinism (EC), that is the major expression of anomalies in the physical and intellectual development caused by a severe iodine deficiency. There are presented 5 patients, 4 men and 1 woman, with neurological endemic cretinism (NEC) (n=2) and mixed forms of the disease (n=3), coming from 2 old endemic areas (medium urinary iodine excretion in the studied patients 20.8 g/day), diagnosed and treated in outpatients clinics or in hospitals. Four patients are members of the same family. The age of the patients is between 36 and 84 years old, the average age being 69. The intellectual capacity was assessed by using the Wechsler and Raven tests, the average intelligence quotient (IQ) value was of 20.8 points ? 1.47. The thyroid volumes (TV) were estimated by palpatory method and by ultrasonography and were between 8.7-200 ml. TSH values in studied patients ranged between 3.8-26 IU/ml and free T4 ranged between 0.272-1.22 ng/dl. Aggregation of more cases of endemic cretinism in the same family suggests the occurrence of some genetic factors. In conclusion, the old age (over 70 years old) of 4 cretins shows they are remnants of the old IDD endemia. However, there is also an isolated case of middle age (36 years old) suggesting an inadequate iodine intake, despite a law regarding salt iodization which has been operating since 1962. More attention to the universal salt iodization and to consumption of iodized salt in the rural areas is necessary.

Objectives. The objective of this retrospective study was to evaluate weight gain at 3 months following insulin therapy initiation and to determine if it is due to fat or fat free tissue. Methods. Fifty-eight patients with T2DM and initiation of insulin therapy were evaluated. Body composition was assessed with InBody720 device (Biospace, Korea) before and 3 months after the initiation of insulin therapy. Results. The insulin therapy was initiated with basal insulin in 84.48% of the cases. The initial dose of insulin was 22.76±12.89 units/day and increased at 3 months to 30.81±18.49 units/day (p<0.001). The initial HbA1c was 9.86±2.02% and decreased to 7.58±1.19% (p<0.001). The body weight increased from 87.01±17.37 kg to 88.04±16.64 kg (p=0.026). The fat body mass and the percent of fat decreased with no statistical significance; the intracellular and extracellular body water increased significantly (intracellular: 26.30±5.96 vs. 27.26±6.16; extracellular: 16.61±3.63 vs. 17.03±3.84; p<0.001). Conclusion. During the first 3 months after initiation of insulin therapy a modest weight gain due to increase in the body water after restoration of the metabolic balance was observed.

Context. Polycystic ovary syndrome (PCOS) or disease (PCOD) is one of the most common causes of female infertility. Objective. The objective of this study was to find out the influence of insulin on LH, testosterone and SHBG in diffrent PCOS categories. Experimental design. A total of 800 women who were subjected to infertility treatment at infertility clinics were selected. About 60 healthy females with regular menstrual cycles were considered as control. The data were collected from hospital records using subject’s consent. Results. Relationship of insulin to LH and testosterone was positive and significant (p<0.05) in the entire PCOS group and in five PCOS subcategories with increased LH rise (i.e. 1.3, 2, 3, 4 & 5 times of LH rise in relation to FSH levels in each group respectively). The correlation pattern showed an increasing trend from lower to increased rise of LH compared to FSH. The relationship between insulin and SHBG was negative and significant (p<0.05) in all PCOS subcategories, except for the group having similar LH and FSH levels and also in another group with FSH levels higher than LH levels. A strong positive correlation was established between insulin and SHBG in normal subjects. The percentage of negative correlation was strong in PCOD subcategories with elevated rises of LH. Conclusion. This study established the influence of insulin on other marker hormones (LH, testosterone an SHBG) in various PCOS categories in view of their percentage of relationship.

Context. The detrimental effects of hyperinsulinemia on human ovaries during follicular development process have been shown in various studies, particularly in women with polycystic ovary syndrome. To our knowledge there is no study regarding the effect of insulin resistance (IR) on the intrauterine insemination (IUI) success in women with unexplained infertility (UEI). Objective. To evaluate the effects of IR on the occurrence of pregnancy among infertile women undergoing ovulation induction (OI) with IUI for UEI. Design. Prospective cohort study. Subjects and Methods. 173 patients who met the criteria for UEI and under the age of 35 were included in this study. All women underwent OI with IUI and, subsequently, they were divided into two groups based on the presence of pregnancy. Data reviewed for analysis were demographic, clinical, and laboratory features. Results. There were 37 (21.4%) cycles with pregnancy and 136 (78.6%) cycles without pregnancy. Median infertility duration was significantly lower in the pregnant group when compared with non-pregnants (p=0.018). The mean number of previous cycles per patient was also lower in this group (p=0.028). No significant differences were found between the groups in terms of other variables. Levels of insulin, fasting glucose and HOMA-IR were also similar between the two groups. Conclusions. IR calculated by using HOMA-IR index has no positive or negative effect on the occurrence of pregnancy in women undergoing OI therapy with IUI for UEI.
