RESUMO
Prevalence, risk factors and metabolic complications of overweight/obesity (OW/OB) are not well described in the childhood survivors of acute lymphoblastic leukemia (ALL). Longitudinal changes in body mass index-z score (BMIz) from diagnosis to the last follow-up visit after the end of treatment were evaluated in 73 children at first complete remission. Of them, 40 were tested for adipokine profiles at visit. The mean BMIz increased gradually from diagnosis (0.07 ± 1.68) to the end of dexamethasone containing reinduction therapy (0.70 ± 1.48, P:0.007), followed by a fall at the end of treatment (0.15 ± 1.24) and a rise again at visit (0.40 ± 1.23, P:0.007). OW/OB percentage of 15% at diagnosis, increased to 35% at visit (p < 0.05). Post-treatment OW/OB in survivors was related with being OW/OB at diagnosis (OR 5.4, 95% CI [0.94-31.7]; P = 0.02) and after dexamethasone containing reinduction therapy (OR 5.1, 95% CI [1.1-21.4]; P = 0.05), but not with age at diagnosis, gender, treatment intensity and cranial irradiation. Metabolic syndrome (MetS) was more prevalent in survivors (13%) than in Turkish children (2%). As compared with controls, survivors had higher leptin level (8.1 ± 8.6 vs 3.2 ± 2.2 ng/ml, P = 0.01) and leptin/adiponectin ratio (2.1 ± 3.5 vs 0.6 ± 0.5, P = 0.03). Leptin/adiponectin ratio was correlated with HOMA-IR (r: 0.57, P = 0.001). The prevalence of OW/OB and MetS are elevated in the childhood survivors of ALL. Post-treatment OW/OB in survivors is related with OW/OB at diagnosis and dexamethasone containing therapy. Elevated leptin level and leptin: adiponectin ratio may serve as an early sign of metabolic derangement increasing the risk for early cardiovascular disease.
RESUMO
INTRODUCTION: The optimal dietary strategy to improve the metabolic and reproductive endocrine profile in adolescents with obesity and polycystic ovary syndrome is undefined. This study was conducted to evaluate the efficacy of the MEtabolic Syndrome REduction in NAvarra (RESMENA) diet versus a control diet based on American Heart Association (AHA) recommendations for the treatment of PCOS in adolescents with PCOS. METHODS: A total of 40 adolescents diagnosed with PCOS between the ages of 13-18 years were randomized to either a RESMENA or control diet for 6 months. Dietary status, anthropometry, body composition, biochemical parameters, and reproductive endocrine hormones were compared between the 2 groups before and after the intervention. RESULTS: Both diet groups showed significant decreases in anthropometric parameters whereas the RESMENA diet provided a greater decrease in all these parameters except neck circumference and fat percentage (p<0.05). At the end of the study fasting insulin, ALT, and total cholesterol levels decreased in both control and RESMENA group, HbA1c, HOMA-IR, and hsCRP levels decreased and QUICKI score increased in the RESMENA group (p<0.05). There was no statistical difference in the androgen levels of the control group compared to the baseline. In the RESMENA group, there was a significant decrease in total testosterone, free testosterone, 17-OH progesterone, androstenedione, LH levels and LH/FSH ratio and free androgen index and a significant increase in SHGB levels (p<0.05). CONCLUSIONS: Both dietary patterns resulted in significant improvement in anthropometric measurements and body composition, but the RESMENA diet showed beneficial effects on insulin resistance parameters and androgen levels.
RESUMO
Introduction: The mRNA-based BNT162b2 (Pfizer-BioNTech) vaccine has been shown to elicit robust systemic immune response and confer substantial protection against the severe coronavirus disease (COVID-19), with a favorable safety profile in adolescents. However, no data exist regarding immunogenicity, reactogenicity and clinical outcomes of COVID-19 vaccines in adolescents with type 1 diabetes (T1D). In this prospective observational cohort study, we examined the humoral immune responses and side effects induced by the BNT162b2 vaccine, as well as, the rate and symptomatology of laboratory-confirmed COVID-19 vaccine breakthrough infections after completion of dual-dose BNT162b2 vaccination in adolescents with T1D and compared their data with those of healthy control adolescents. The new data obtained after the vaccination of adolescents with T1D could guide their further COVID-19 vaccination schedule. Methods: A total of 132 adolescents with T1D and 71 controls were enrolled in the study, of whom 81 COVID-19 infection-naive adolescents with T1D (patient group) and 40 COVID-19 infection-naive controls (control group) were eligible for the final analysis. The response of participants to the BNT162b2 vaccine was assessed by measuring their serum IgG antibodies to the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), 4-6 weeks after the receipt of first and second vaccine doses. Data about the adverse events of the vaccine was collected after the receipt of each vaccine dose. The rate of COVID-19 vaccine breakthrough infections was evaluated in the 6-month period following second vaccination. Results: After vaccinations, adolescents with T1D and controls exhibited similar, highly robust increments in anti-SARS-CoV-2 IgG titers. All the participants in the patient and control groups developed anti-SARS-CoV-2 IgG titers over 1,050â AU/ml after the second vaccine dose which is associated with a neutralizing effect. None of the participants experienced severe adverse events. The rate of breakthrough infections in the patient group was similar to that in the control group. Clinical symptomatology was mild in all cases. Conclusion: Our findings suggest that two-dose BNT162b2 vaccine administered to adolescents with T1D elicits robust humoral immune response, with a favorable safety profile and can provide protection against severe SARS-CoV-2 infection similar to that in healthy adolescents.
RESUMO
Purpose: Our study aimed to examine the effects of blue light exposure on prepubertal male rats' puberty and testis tissue. Methods: Eighteen 21-day-old male Sprague Dawley rats were divided into three groups consisting of six rats in each group: Control Group (CG), Blue Light-6 hours (BL-6), and Blue Light-12 hours (BL-12). CG rats were maintained with 12/12-hour light-dark cycles. The rats of BL-6 and BL-12 were exposed to blue light (450-470nm/irradiance level 0.03uW/cm2) for 6 hours and 12 hours, respectively. Rats were exposed to blue light until the first signs of puberty. The ELISA method was used to analyze the serum levels of FSH, LH, testosterone, DHEA-S, leptin, ghrelin, melatonin, glutathione, glutathione peroxidase, and malondialdehyde. Testes were dissected for histomorphological examination. Results: The medians of the pubertal entry days of the CG, BL-6, and BL-12 were 38th, 30th, and 28th days, respectively. (p:0.001) The FSH, LH, and testosterone concentrations of all groups were similar. The FSH concentration increased as the LH concentration increased (r: 0.82 p: 0.001). The serum LH concentration increased as serum testosterone, and DHEAS decreased, respectively (r: -0.561, p: 0.01) (r:-0.55 p:0.01). Testicular lengths and weights of the BL groups were smaller compared to CG (p: 0.03),(p: 0.04). GPx was higher for BL-6 and BL-12 than the CG (p:0.021, p:0.024). Testis tissue was compatible with the pubertal period in all groups. As the blue light exposure time increased, spermatogenesis was suppressed, and capillary dilatation and edema in the testis tissue increased. Conclusion: Our study is the first to show the effects of blue light exposure on male rats' puberty process. And we showed that exposure to blue light and the duration of exposure lead to precocious puberty in male rats. The blue light exposure suppressed spermatogenesis, marked vasodilatation in the interstitial area of the testis, and disrupted the integrity of the basement membrane. These findings intensified with increasing exposure time.

Objective: This study was designed to examine the effect of blue light exposure and exposure time on puberty in an animal model. Methods: Eighteen 21-day-old female Sprague Dawley rats were divided into three equal groups which were: control group (CG); blue light-6 hours (BL-6); and blue light-12 hours (BL-12). CG rats were maintained with 12/12-hour light-dark cycles. The animals in BL-6 and BL-12 were exposed to blue light of wavelength 450-470 nm and intensity of 0.03 uW/cm2 for 6 and 12 hours, respectively. Exposure to blue light continued until the first signs of puberty. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, testosterone, dehydroepiandrosterone sulfate (DHEA-S), leptin and melatonin were measured. Subsequently the ovaries and uterus were examined histomorphologically. Results: The median day of puberty start was 38, 32 and 30 for the CG, BL-6, and BL-12 groups, respectively (p=0.001). FSH, testosterone, DHEA-S, and leptin concentrations of all groups were similar. However, LH and estradiol concentrations in BL-6 were higher compared to CG (p=0.02). There was a negative correlation between blue light exposure, exposure time, and melatonin concentrations (r=-0.537, p=0.048). Ovarian tissue was compatible with puberty in all groups. As blue light exposure time increased, capillary dilatation and edema in the ovarian tissue increased. Prolonged exposure was associated with polycystic ovary-like (PCO) morphological changes and apoptosis in granulosa cells. Conclusion: These results suggest that exposure to blue light and the duration of exposure induced earlier puberty in female rats. As the duration of blue light exposure increased, PCO-like inflammation, and apoptosis were detected in the ovaries.

OBJECTIVES: Alexithymia and low health literacy are the barriers of self-management. This study aims to examine the relationship between alexithymia, health literacy and diet quality in obese adolescents, and their effects on anthropometric and biochemical markers. METHODS: The 20-item Toronto alexithymia scale (TAS-20) was used to determine the alexithymic traits of the adolescents, and "The Newest Vital Sign" (NVS) scales were used to determine their health literacy levels. Diet quality was evaluated with the Healthy Eating Index-2010 (HEI-2010). RESULTS: 39.7% of the obese adolescents were alexithymic, and 69.4% of alexithymics and 35.1% of non-alexithymics had metabolic syndrome. Alexithymic adolescents were lack of adequate health literacy. There were positive correlations between alexithymia scores and insulin, triglyceride, systolic and diastolic blood pressure levels, and all anthropometric values except height (p<0.05). There was a negative correlation between alexithymia scores and health literacy scores (p<0.05). There were negative correlations between health literacy and alexithymia scores, insulin, total cholesterol, triglyceride, ALT, systolic, diastolic blood pressure levels and all anthropometric values except height, and positive correlation was observed between health literacy scores and diet quality (p<0.05). Total HEI score was negatively correlated with waist circumference, neck circumference, body weight, BMI, triglyceride, AST, ALT, systolic and diastolic blood pressure, and positively correlated with health literacy and HDL levels (p<0.05). CONCLUSIONS: As alexithymia severity increased in obese adolescents, the degree of obesity and the incidence of metabolic syndrome increased while the level of health literacy decreased. The increase in health literacy levels, on the other hand, decreased the level of alexithymia and increased the quality of the diet.

Objective: This study was planned to determine the effects of carob use on puberty because of the observation of early puberty or pubertal variants due to the long-term use of carob in our clinic. Methods: Forty-eight Wistar albino rats, on postnatal day 21, were assigned into two groups female (n=24) and male (n=24). Groups were divided into four groups Control, and Carob-150, Carob-300, and Carob-600. Ceratonia siliqua L. extract was given to rats in a 0.5% carboxymethylcellulose (CMC) solution. CMC (0.5%) was given to the control, Ceratonia siliqua L. extract was given 150 mg/kg/day to the Carob-150, 300 mg/kg/day to the Carob-300, 600 mg/kg/day to the Carob-600 by oral gavage. The treatments were performed once daily until the first sign of puberty. Serum follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, total testosterone, leptin, glutathione, glutathione peroxidase (GPx), and malondialdehyde were measured by commercial rat-specific ELISA kits. Testis, uterus and ovarian tissue were examined histologically. Results: The median time of preputial separation in male rats was 38th, 31st, 31st, and 31st days in the Control, Carob-150, Carob-300, and Carob-600 groups, respectively (p=0.004). The median day of vaginal opening day was the 39th, 31st, 34th, and 31st days in the Control, Carob-150, Carob-300, and Carob-600 groups, respectively (p=0.059). FSH, LH, testosterone (male), estradiol (female) and leptin levels of the groups were similar. However, GPx levels were higher in male and female animals given C. siliqua extract compared to the Control (male p=0.001 and female p=0.008). Testicular and ovarian tissues were concordant with the pubertal period in all groups. As the dose of Ceratonia siliqua extract increased, it induced spermatogenesis and spermiogenesis, causing abnormal changes, such as ondulation in the basement membrane, capillary dilatation, and increased congestion in males. In females, edema in the medulla gradually increased with increased dosage, and granulosa cell connections were separated in Carob-300 and Carob-600 groups. Conclusion: This study demonstrated that C. siliqua caused early puberty and increased spermiogenesis and folliculogenesis. Antioxidant mechanisms were impaired with increasing dose, possibly leading to tissue damage at high doses.

It is well-known that in children with type 1 diabetes (T1D), the frequency of Celiac disease (CD) is increased due to mechanisms which are not fully elucidated but include autoimmune injury as well as shared genetic predisposition. Although histopathologic examination is the gold standard for diagnosis, avoiding unnecessary endoscopy is crucial. Therefore, for both clinicians and patients' families, the diagnosis of CD remains challenging. In light of this, a joint working group, the Type 1 Diabetes and Celiac Disease Joint Working Group, was convened, with the aim of reporting institutional data and reviewing current international guidelines, in order to provide a framework for clinicians. Several controversial issues were discussed: For CD screening in children with T1D, regardless of age, it is recommended to measure tissue transglutaminase-immunoglobulin A (tTG-IgA) and/or endomysial-IgA antibody due to their high sensitivity and specificity. However, the decision-making process based on tTG-IgA titer in children with T1D is still debated, since tTG-IgA titers may fluctuate in children with T1D. Moreover, seronegativity may occur spontaneously. The authors' own data showed that most of the cases who have biopsy-proven CD had tTG-IgA levels 7-10 times above the upper limit. The decision for endoscopy based solely on tTG-IgA levels should be avoided, except in cases where tTG-IgA levels are seven times and above the upper limit. A closer collaboration should be built between divisions of pediatric endocrinology and gastroenterology in terms of screening, diagnosis and follow-up of children with T1D and suspicious CD.

BACKGROUND: Fever is one of the leading causes of hospital admissions in children. Although there are many ways to measure body temperature, the optimal method and the anatomic site are still controversial. In this study, we aimed to evaluate the performance of new methods of measuring body temperature and to compare the accuracy, sensitivity and specificity of these methods. METHODS: The body temperatures of the patients who were hospitalized as inpatients or who presented to the emergency room as outpatients between November 2014- March 2015 were measured and recorded. Mercury and digital axillary measurements, tympanic, temporal artery and non-contact skin temperatures were measured. Measurements were compared with each other. RESULTS: According to our results temperature tends to increase over time for up to 8 minutes after placement when using axillary thermometers. Non-contact skin thermometers should be used only for follow-up of patients with fever, because of their low sensitivity and low negative predictivity. At the first examination, tympanic thermometers and axillary thermometers may be preferable for the diagnosis of fever. CONCLUSIONS: According to our results, using non-contact thermometers seems feasible and logical during the follow-up ofpatients with fever, but not in cases whose exact body temperature should be known. For the first examination of the patient to diagnose fever, tympanic thermometers and axillary thermometers may be preferable. Future studies are warranted to expose the optimum way of measuring body temperature in children.

AIMS: This study aimed to investigate whether supplemental soluble fiber, oat ß-glucan, has any effect on glycemic control and variability of adolescents with type 1 diabetes mellitus. METHODS: This study was conducted in 30 adolescents with type 1 diabetes mellitus and it consisted of three phases lasting one week. At Phase I, all subjects followed a standard diet program. For Phase II and Phase III, the subjects continued their standard diet program and added natural oat flakes containing 3â¯g/day and 6â¯g/day ß-glucan, respectively. Glucose levels were monitored by continuous glucose monitoring (CGM). The maximal, minimal, mean and daytime and night blood glucose levels, percentages of glucose values in a target range and below and above a target values were calculated for each of the phases. Premeal, postmeal, peak blood glucose values and peak times of meals were evaluated for each of the phases. Glycemic variability was measured via SD, CV, MAGE, IQR, MODD, LBGI, HBGI, and CONGA parameters. RESULTS: The maximal, mean and daytime and night blood glucose levels were the lowest at Phase III (pâ¯<â¯0.05). Minimal blood glucose levels were the highest at Phase III (pâ¯<â¯0.05). Phase I, II, and III showed similar durations elapsed for Level 2 and Level 1 hypoglycemia, euglycemia, Level 1 and Level 2 hyperglycemia (pâ¯>â¯0.05). Premeal and postmeal blood glucose levels were lowest at Phase III for breakfast, lunch, and overall (pâ¯<â¯0.05). The lowest peak blood glucose levels were detected at Phase III for breakfast, lunch, dinner and overall (pâ¯<â¯0.05). Phase III also showed delayed peaks for all time-points (pâ¯<â¯0.05 for each) compared to other phases. Phase III had significantly lower levels of SD, CV, LBGI, and CONGA levels than those in either Phase I or Phase II (pâ¯<â¯0.05 for each). CONCLUSION: 6â¯g/day oat ß-glucan have favorable outcomes in glycemic control and variability in adolescents with type 1 diabetes mellitus.

Objective To determine whether first-voided urinary LH (FV-ULH) - level measurement can adequately assess pubertal suppression as much as standard tests can. Subjects and methods The study group included patients with central precocious puberty and rapidly progressing early puberty who received up to 3 - 4 doses of GnRHa therapy monthly and did not have adequate hormonal suppression after GnRH stimulation (90-minute LH level > 4 IU/L). Design: All of the participants underwent an LHRH test just after admission to the study. According to the stimulated peak LH levels, the patients were divided into 2 groups and followed until the end of the first year of treatment. The concordance between FV-ULH and stimulated LH levels was assessed. Results The FV-ULH levels in patients with inadequate hormonal suppression were significantly high compared to patients with adequate hormonal suppression. FV-ULH levels were very strongly correlated with stimulated LH levels (r = 0.91). Its correlation with basal LH levels was significant (r = 0.65). However, this positive correlation was modestly weakened after the first year of treatment. The cutoff value for FV-ULH of 1.01 mIU/mL had the highest sensitivity (92.3%) and specificity (100%). Conclusion FV-ULH levels, using more reliable and sensitive assay methods, can be used to monitor the adequacy of GnRHa therapy.

This study evaluated the nutritional status of Syrian refugees in the early adolescent period living in different vulnerable settings. Nutritional assessment of Syrian refugee adolescents is often neglected but essential for a healthy physical, pubertal and mental development. Growth parameters of Syrian refugee adolescents going to a public school in an urban area and in a temporary protection center (TPC) were recorded along with the Turkish adolescents. Stunting percentages were similar between the groups (p = 0.811). While the proportion of children with a BMI over 85th percentile were significantly higher among Syrian adolescents living in TPC, Turkish children have the highest percentage of underweight (p = 0.01). Both food insecurity and unhealthy weight gain continue to be major concerns for refugee adolescents after their resettlement to a host country. The findings suggest that nutritional assessment and intervention at early adolescence is critical for Syrian refugees depending on their living conditions.

Objective: Obesity is a common epidemic issue in all over the world. In order to prevent obesity it is essential to know about obesity and its detrimental consequences. This study aimed to evaluate children's awareness about obesity and to determine the associations between level of awareness, healthy lifestyle, dietary habits and risk factors for metabolic syndrome.Methods: Two hundred and thirty-six overweight children (119 boys and 117 girls) aged 10-14 years were enrolled to the study. Anthropometric and biochemical measurements were taken and metabolic syndrome (MetS) definition were done according to the International Diabetes Federation (IDF) consensus and divided into two groups as MetS (+) and MetS (-). Obesity awareness scale (OBA) and Adapted Healthy Lifestyle-Diet Index for Turkey (HLD-TR) were performed.Results: Among children, the prevalence of having MetS was found as 26.3%. Obesity awareness and HLD-TR index sores were lower in MetS (+) group than MetS (-) group. Metabolic syndrome related biochemical parameters and anthropometric measurements were associated with obesity awareness level of the children. The binary logistic regression model shows that a one-unit increase in the OBA index score increases the odd of not having MetS for 1.12 times after adjustments for age, gender, body mass index, and HLD-TR index score.Conclusions: Increased awareness about obesity among children will help to reduce the risk of metabolic syndrome, type 2 diabetes and atherosclerotic cardiovascular diseases in the future.

Objective: Non syndromic monogenic obesity is a rare cause of early onset severe obesity in the childhood period. This form may not be distinguishable from other forms of severe obesity without genetic analysis, particularly if patients do not exibit any physical abnormalities or developmental delay. The aim of this study was to screen 41 different obesity-related genes in children with non-syndromic early onset severe obesity. Methods: Children with severe (body mass index-standard deviation score >3) and early onset (<7 years) obesity were screened by next-generation sequencing based, targeted DNA custom panel for 41 known-obesity-related genes and the results were confirmed by Sanger technique. Results: Six novel variants were identified in five candidate genes in seven out of 105 children with severe obesity; two in SIM1 (p.W306C and p.Q36X), one in POMC (p.Y160H), one in PCSK1 (p.W130G fs Ter8), two in MC4R (p.D126E) and one in LEPR (p.Q4H). Additionally, two previously known variations in MC4R were identified in four patients (p.R165W in three, and p.V166I in one). Conclusion: We identified six novel and four previously described variants in six obesity-related genes in 11 out of 105 childrens with early onset severe obesity. The prevalence of monogenic obesity was 10.4% in our cohort.

Objective: A close diabetes team-patient relationship is required for establishing satisfactory metabolic control. The purpose of this study was to investigate the effect of a telehealth system on diabetes control. Methods: The study was carried out between June 2015 and January 2016 at the Gazi University Faculty of Medicine, Pediatric Endocrinology Department. The telehealth system was developed by the diabetes team. The demographic characteristics, frequency of use and hemoglobin A1c (HbA1c) changes of type 1 diabetic (T1DM) patients using this communication network were analysed. Results: Eighty two patients [43 (52.4%) females, mean (±standard deviation) age 10.89±4 years] used the telehealth system. Fourteen (17.1%) of the cases were on pump therapy and 59 (72.0%) were counting carbohydrates. The individuals with diabetes or their families preferred WhatsApp communication. Whatsapp provided a means for instant messaging in most instances (57.3%), contact with diabetes education nurse (32.9%) and consultation with the diabetes team about insulin doses and blood glucose regulation (42.7%). HbA1c values after six months were significantly lower in patients/parents calling frequently (p<0.001) compared with HbA1c values recorded at the beginning of the study. Conclusion: Increase in frequency of counselling by the diabetes team led to improved blood glucose control in T1DM patients. A telehealth system is useful for early detection of the need for changes in treatment and for intervention. It also promoted better self care.

Akgül S, Hüsnü S, Derman O, Özmert E, Bideci A, Hasanoglu E. Mental health of Syrian refugee adolescents: how far have we come? Turk J Pediatr 2019; 61: 839-845. Among the consequences of war, its impact on the mental health of children and adolescents is one of the most significant. A previous study from our team evaluated the psychiatric symptoms of Syrian refugee adolescents living in one of Turkey`s Temporary Accommodation Centers (TACs) in 2016. Findings suggested that mental health had been compromised in these teens. Since then many measures have been taken to address this problem. The aim of the current study was to re-assess the mental health status of adolescents living in the same center. A total of 76 adolescents (35 female, 41 male) aged between 12-18 years (14.2 ± 0.83 years) received the Brief Symptom Inventory (BSI) which assessed their anxiety, depression, negative self-concept, somatization and hostility levels in addition to a Global Severity Index (GSI). Results > 1.0 indicated psychopathological symptoms. All BSI sub-scores decreased from 2016 to 2019 showing significant improvement in psychopathological symptoms. The most significant change was in the GSI score which decreased from 2.15 to 0.8. For the 2019 participants a significant correlation was found between years of stay at the camp and the depression subscale. Evaluation to assess gender differences found that adolescent girls reported significantly higher scores than males in anxiety, depression, somatization and the global severity index. This study has shown that interventions designed to tackle post-traumatic stress symptomology may have been effective in improving the mental health status of these teens and can provide a roadmap for tackling existing issues in vulnerable conditions. Additionally, females are under higher risk for psychopathology so gender targeted interventions may specifically be necessary to deal with such issues.

Single nucleotide polymorphisms (SNPs), the most common genetic variations in human genome, can manage the predisposition of certain complex diseases or situations such as obesity. Genetic polymorphisms also play an important role as they can impact a population's susceptibility to being overweight or obese and developing related chronic complications such as hypertension, coronary heart disease, diabetes and cancer. The present study comprised of 193 unrelated healthy volunteers (120 females and 73 males) with Turkish origin. Only female adolescents (n = 110) were divided into 2 categories according to their BMI values as overweight (BMI ≥ 25) and normal (18.5 < BMI < 25) according to WHO classification. Genomic DNA was isolated from venous blood samples and genotyping of DENND1A rs10818854 and CYP19A1 rs2414096 variants was performed on Roche Light Cycler 2.0 Real-Time PCR platform. Serum hormone levels were analyzed by Electrochemiluminescent Immunoassay (ECLIA; Roche diagnostics). The genotype distributions were consistent with the Hardy-Weinberg equilibrium for both SNPs in the studied population (p > 0.05). The genotype distribution of DENND1A rs10818854 was determined for the first time in Turkish population and the variant allele frequency was found as 0.095. According to reduced sex hormone-binding globulin levels and increased free androgen index in the present study, obesity was linked with hyperandrogenism in female subjects. Both polymorphisms were investigated as potential genetic susceptibility markers for obesity and neither DENND1A nor CYP19A1 showed any associations.

BACKGROUND: Vitamin D, an important factor in calcium-phosphate homeostasis, has recently been suggested to play an important role in the pathogenesis of numerous chronic conditions such as hyperandrogenism. The aim of this study was to investigate the relationship between vitamin D status and premature adrenarche (PA). METHODS: A total of 71 girls with PA and 52 healthy girls, as the control group, were recruited. Axillary and/or pubic hair development before the age of 8 years was defined as PA. Bone age and anthropometric measures including height, weight, and body mass index (BMI) were obtained. 25-Hydroxyvitamin D (25(OH)D), fasting plasma glucose and insulin were measured. Vitamin D insufficiency was defined as <20 ng/mL. RESULTS: The PA patients had older bone age, higher BMI standard deviation score, homeostasis model of assessment-insulin resistance (HOMA-IR), and androgen but lower 25(OH)D than the control group. HOMA-IR and dehydroepiandrosterone sulfate were also higher in PA patients with vitamin D insufficiency compared with those with normal vitamin D. There was a negative correlation between 25(OH)D and HOMA-IR. CONCLUSION: Low vitamin D is associated with PA; and insulin resistance may be a factor in this association.
