Preconceptional Counseling in Women with Hyperthyroidism.

Preconception evaluation of couples wishing to conceive is an important step toward a healthy pregnancy and it is especially important in people with a chronic condition or at genetic risk. The most common endocrine disorders in women at reproductive age are those involving the thyroid gland and it is well recognized that hyperthyroidism (HT), over-function of the thyroid gland, is associated with risks of maternal, fetal, and neonatal complications. The aim of this paper is to review the latest evidence regarding the components of preconception counseling in women with HT that contemplate a pregnancy. We also want to raise awareness among healthcare professionals about the importance of periconceptional counseling in improving pregnancy outcomes and avoid maternal and fetal complications related to thyroid dysfunction. In women with Graves' disease seeking pregnancy, it is essential to discuss all the treatment options along with the associated risks and benefits. Extensive prospective studies are still needed to understand the implications of current recommended strategies for the management of HT in preconception and during pregnancy.

Uric Acid in Primary Hyperparathyroidism: Assessment of Surgical versus Conservative Approach.

Introduction: Although suggested in early papers, the association between primary hyperparathyroidism (PHPT) and hyperuricemia is still debated, as is the potential benefit of parathyroidectomy compared to conservative treatment in serum uric acid (SUA) metabolism. Material and Methods: Our retrospective study of 125 Caucasian PHPT patients with surgical criteria evaluated between 2017 and 2021 at Elias Emergency and University Hospital, Bucharest, Romania aims to describe the characteristics of hyperuricemia in PHPT patients and to assess the differences in SUA levels between 38 surgically cured and 41 conservatively managed patients. Results: Our hyperuricemic PHPT patients (N=34) had significantly higher levels of calcium (11.55[11.05;12.42] vs. 11.2[10.8;11.96], p=.039) than the normouricemic subjects (N=91). At baseline, SUA correlated with age, serum total calcium (p=.004, r=.328), creatinine, triglycerides, and magnesium levels. A linear regression model identified calcium as a covariate with unique contribution for SUA variability. After successful parathyroidectomy, the 38 cured patients showed significantly lower serum calcium (9.3[8.7;9.75] vs. 11.55[11;12.12], p .001) and SUA (4.95[3.52;6.3] vs. 5.65[4.49;7.45], p=.011) levels compared to baseline. Conclusions: Hyperuricemic PHPT patients have significantly higher levels of serum calcium, which is also an independent determinant of SUA variability. Patients who undergo successful parathyroidectomies show a significant decrease in SUA during 1 year of follow-up.

Degraded Bone Microarchitecture in Women with PHPT-Significant Predictor of Fracture Probability.

Introduction: Patients with primary hyperparathyroidism (PHPT) experience bone mineral density (BMD) loss and trabecular bone score (TBS) alteration, which current guidelines recommend assessing. Considering TBS alongside BMD for a 10-year fracture risk assessment (FRAX) may improve PHPT management. Design: Retrospective, cross-sectional study composed of 49 Caucasian females (62 ± 10.6 years, 27.7 ± 0.87 kg/m2) with PHPT and 132 matched control subjects (61.3 ± 10.5 years, 27.5 ± 0.49 kg/m2) evaluated in 3 years. We assessed lumbar spine (LS) and femoral neck (FN) BMD, T and Z scores (GE Healthcare Lunar Osteodensitometer) and TBS (iNsight 1.8), major osteoporotic fracture (MOF), and hip FRAX. Results: Patients with PHPT had statistically lower mean values for lumbar spine bone mineral density (LS BMD) (0.95 ± 0.25 vs 1.01 ± 0.14 g/cm2, P = .01), LS T-scores (-2 ± 0.2 vs -1.4 ± 0.1 SD, P = .009), LS Z scores (-0.9 ± 0.19 vs -0.1 ± 0.11 SD, P = .009), femoral neck bone mineral density (FN BMD) (0.79 ± 0.02 vs 0.83 ± 0.01 g/cm2, P = .02), FN T-scores (-1.8 ± 0.13 vs -1.5 ± 0.07 SD, P = .017), FN Z scores (-0.51 ± 0.87 vs -0.1 ± 0.82 SD, P = .006), and TBS (0.95 ± 0.25 vs 1.01 ± 0.14 g/cm2, P = .01) compared with control subjects. 22.4% of patients with PHPT had degraded microarchitecture (TBS < 1.2) vs. 7.6% in control group (χ2 = 0.008). PHPT proved to be a covariate with unique contribution (P = .031) alongside LS BMD (P = .040) in a linear regression model [R 2 = 0.532, F(4,16) = 4.543] for TBS < 1.2. TBS adjustment elevated MOF FRAX both for PHPT (4.35 ± 0.6% vs 5.25% ± 0.73%, P < .001) and control groups (4.5 ± 0.24% vs 4.7% ± 0.26%, P < .001) compared with BMD-bases FRAX, but also increased differently between the 2 study groups (1.1-folds for PHPT patients and 1.04 for control subjects, P = .034). Conclusion: Compared with control, TBS-adjusted FRAX provides significantly higher MOF risk than BMD-based FRAX in PHPT women.

Preconception Counseling in Patients with Hypothyroidism and/or Thyroid Autoimmunity.

Preconception counseling is an essential tool for preventing adverse pregnancy outcomes associated with thyroid dysfunction. The high prevalence of thyroid disease among women of reproductive age, and the increased risk of adverse pregnancy outcomes associated with thyroid dysfunction, emphasize the necessity for well-established screening and treatment criteria in the preconception period. We therefore conducted a literature review for relevant information on the screening, diagnosis and treatment of subclinical and overt hypothyroidism in women seeking pregnancy. While screening for thyroid disease is recommended only in the presence of risk factors, iodine supplementation should be recommended in most regions, with higher doses in areas with severe deficiency. Known hypothyroid women should be counseled about increasing their levothyroxine dose by 20-30% in the case of suspected or confirmed pregnancy (missed menstrual cycle or positive pregnancy test). Treating subclinical hypothyroidism appears to be beneficial, especially in the presence of autoimmunity or in patients undergoing artificial reproductive techniques. Regarding the management of TPOAb negative SCH women or euthyroid women with positive TPOAb, further research is necessary in order to make evidence-based recommendations.

Body Composition as a Modulator of Bone Health Changes in Patients with Inflammatory Bowel Disease.

BACKGROUND: Bone impairment of multifactorial etiology is a common feature in inflammatory bowel disease (IBD). Body composition parameters, which might be selectively modified in these patients, are important determinants of bone strength. Our aim was to investigate the relationship between components of body composition and bone parameters in IBD patients. METHODS: This is a cross-sectional, retrospective study including 80 IBD patients (43 women, 37 men). Lumbar spine (LS), femoral neck (FN) and whole body DXA scans were performed to analyze regional bone mineral density (BMD), as well as body composition, including appendicular skeletal muscle mass index (ASMI), total and visceral fat mass (VAT). Trabecular bone score (TBS) was assessed using iNsight Software. RESULTS: Twenty (25%) IBD patients had inadequate LS-BMD z scores (<=-2DS). Lean mass (LM) was a significant determinant of LS-BMD, after adjusting for age, gender, BMI and fat mass (p < 0.01), while fat mass% remained associated with FN-BMD (p < 0.01). TBS correlated positively with BMI (r = 0.24, p < 0.05), LS-BMD (r = 0.56, p < 0.001), ASMI (r = 0.34, p < 0.001) and negatively with VAT/total fat% (r = -0.27, p < 0.05). Multivariate analysis showed that ASMI, LS-BMD (positively) and VAT/total fat% (negatively) were independently associated with TBS. CONCLUSIONS: In IBD patients, skeletal muscle mass and fat percentage and distribution are important factors associated with bone health.

Platelet Activation and Inflammation in Patients with Papillary Thyroid Cancer.

BACKGROUND: The primary endpoint was to analyze the preoperatory inflammatory markers and platelet indices in papillary thyroid cancer (PTC) patients compared with patients with benign thyroid pathology. The secondary endpoints were to analyze the relationship between these markers and the pathological features of PTC and to compare their pre- and postoperative levels in PTC patients. METHODS: In this retrospective case-control study, we analyzed the files of 1183 patients submitted to thyroidectomy between January 2012 and December 2018. A total of 234 patients with PTC (mean age 51.54 ± 13.10 years, 84.6% females) were compared with an age-, gender- and BMI-matched control group of 108 patients with histologic benign thyroid disorders. RESULTS: PTC patients had higher platelet count (PLT) (p = 0.011), plateletcrit (PCT) (p = 0.006), neutrophil (p = 0.022) and fibrinogen (p = 0.005) levels. Subgroup analysis showed that PTC females had higher PLT (p = 0.006), PCT (p < 0.001) and erythrocyte sedimentation rate (ESR) (p = 0.005), while males had higher neutrophil (p = 0.040) levels. Papillary thyroid cancer patients under 55 years had higher PLT (p < 0.001) and PCT (p = 0.010), while patients over 55 years had higher mean platelet volume (p = 0.032), neutrophil-to-lymphocyte ratio (p = 0.013), ESR (p = 0.005) and fibrinogen (p = 0.019) levels. Preoperative values for platelet indices and inflammatory markers were similar to the postoperative determinations in PTC patients. Fibrinogen (AUROC = 0.602, p = 0.02; cut-off = 327.5 mg/dL, Se = 53.8%, Sp = 62.9%) and PLT (AUROC = 0.584, p = 0.012; cut-off = 223.5 × 103/mm3, Se = 73.1%, Sp = 42.6%) were independent predictors of the presence of PTC. CONCLUSIONS: Our data show that fibrinogen and platelet count could be promising, inexpensive, independent predictors for the presence of PTC when compared with benign thyroid disorders.

Lean mass, magnesium, faecal calprotectin and glucocorticoid exposure as risk factors for low bone mineral density in inflammatory bowel disease patients.

BACKGROUND AND AIM: Low bone mineral density (BMD) is a common complication in patients with inflammatory bowel disease (IBD). However, debates are ongoing with regard to the other involved factors, especially in younger patients. This study aimed to evaluate the parameters that contribute to decreased BMD, focusing on premenopausal women and men aged <50 years. METHODS: This study included 81 patients with IBD and 81 age-, sex- and BMI-matched controls. Blood tests were conducted on IBD patients, and a dual-energy X-ray absorptiometry (DXA) scan was performed on both groups. RESULTS: Low BMD and fragility fracture were found to be more prevalent in IBD patients than in healthy subjects (49.3% vs 23.4%, P = 0.001 and 9.8% vs 1.2%, P = 0.01, respectively). Patients with low BMD were older, with a longer disease duration, higher faecal calprotectin (FC) levels and lower magnesium and lean mass (appreciated as appendicular skeletal muscle index (ASMI)). Multiple regression analysis revealed that ASMI, age and use of glucocorticoids were the independent parameters for decreased BMD. Although 91.3% of the patients had a 25-hydroxy vitamin D level of <30 ng/mL, it was not a statistically significant factor for decreased BMD. CONCLUSION: In our study, the levels of vitamin D did not seem to have an important impact on BMD. Conversely, FC, magnesium and lean mass are important factors, suggesting that good control of disease, adequate magnesium intake and increased lean mass can have a good impact on bone metabolism in patients with IBD.

Postoperative Hypoparathyroidism in Patients After Total Thyroidectomy - Experience of a Tertiary Center in Romania.

Background: Post-surgical hypoparathyroidism (PoSH) is a common long-term complication after thyroid surgery. The reported median (range) incidence rates of temporary and permanent PoSH was 27% (19 - 38%) and 1% (0 - 3%) respectively. Material and Methods: We retrospectively analyzed the files of 552 patients who underwent thyroidectomy in our surgery department between 2015- 2017 with the aim to assess the prevalence of PoSH and to identify patient and disease related factors associated with postoperative hypocalcemia. Results: 171 (30.97%) patients developed PoSH, 88.37% transient, 11.63% permanent. The median (IQR) duration of postoperative hypocalcemia was 60 (67.5) days. Preoperative biological parameters were similar in PoSH and the control group, except median (IQR) serum magnesium level that was significantly higher in PoSH group [2.04 (0.17) vs. 1.89 (0.28) mg/dl, p=0.005]. In the subgroup of patients with thyroid carcinoma the surgery duration was longer in PoSH patients compared to the control group [135 (60) vs. 110 (43) minutes, p=0.020]. In patients with PoSH, median post-operative serum calcium was significantly higher in patients with reported difficult surgery [8.2 (0.2) vs. 7.9 (0.6) mg/dl, p=0.043] and the mean serum calcium decrease was higher in patients with cervical neck dissection and lymphadenectomy (1.94 +-0.59 vs. 1.68 +-0.56 mg/dl, p=0.033). Conclusions: Our data show a high prevalence of PoSH that is likely to increase given the rising number of thyroid surgeries being performed. Further research is needed in order to better define this condition, to establish appropriate treatment and preventive measures.

Adiponectin expression in visceral adiposity is an important determinant of insulin resistance in morbid obesity.

INTRODUCTION: Visceral adiposity is associated with decreased serum adiponectin levels, peripheral resistance to insulin and an increased risk of cardio-metabolic complications. However, the link between adiponectin expression in visceral adipose tissue (VAT), its serum levels and metabolic protection is controversial. The aim of this study was to investigate the relationship between the adiponectin gene expression in VAT and clinical and metabolic parameters in patients with severe obesity. MATERIAL AND METHODS: This is a cross-sectional study that included 51 severely obese patients (age 43.24±11.29 years, BMI 45.13±8.67 kg/m2), extensively evaluated clinically and biologically (metabolic tests, serum adiponectin measurements, HOMA-IR) before bariatric surgery. Omental adipose tissue was sampled during the intervention and the relative quantification of adiponectin gene expression was performed by real-time PCR, using beta-actin as reference gene. RESULTS: Adiponectin mRNA in VAT was significantly higher in obese insulin-sensitive patients than in the rest of obese patients (p < 0.05) and negatively correlated with HOMA-IR (r =-0.354, p=0.016) and uric acid (r =-0.304, p=0.045). After adjustment for gender, TG/HDL ratio and uric acid, adiponectin expresion (ß= -0.439, p=0.001), waist circumference (ß=0.467, p=0.001) and serum adiponectin (ß =-0.339, p=0.011) remained significantly associated with HOMA-IR, together explaining more than 50% of its variation. CONCLUSIONS: In severely obese patients, adiponectin gene expression in VAT is negatively correlated with serum levels of uric acid and is an independent determinant, together with anthropometric parameters of visceral obesity and serum adiponectin levels, of insulin resistance.

Cardiovascular risk assessment in osteoporotic patients using osteoprotegerin as a reliable predictive biochemical marker.

Osteoprotegerin (OPG), a member of the tumour necrosis factor receptor (TNFR) superfamily of proteins known to be involved in a large number of biological systems, plays a pivotal role in bone remodelling. In addition to the roles of OPG in bone metabolism, it has been reported to be associated with a high cardiovascular risk in patients with metabolic syndrome. In most cases, the exact functions of OPG remain to be established; however, the widespread expression of OPG suggests that this molecule may have multiple biological activities, mainly in the cardiometabolic environment. The aim of this study was to evaluate the value of OPG as a predictive marker for cardiovascular and metabolic risk in osteoporotic patients. The study group comprised patients with osteoporosis, in order to evaluate the association between OPG serum levels and cardiovascular pathology. Our results revealed significant correlations between classical biochemical bone and metabolic parameters, such as osteocalcin and parathyroid hormone with lipid and glucose biomarkers, sustaining the crosstalk between calcium and bone parameters and cardiovascular risk. The OPG serum level proved to have a significant and independent predictive value for metabolic syndrome (MetS) as a cardiovascular risk standard in osteoporotic patients. The OPG serum levels were increased in patients with MetS as a protective response against the atherosclerotic lesions. The serum levels of 25­hydroxy vitamin D had significant and independent predictive value for cardiovascular and metabolic risk in our subjects, sustaining the active role of vitamin D beyond the area of bone metabolism.

Serum immunoglobulin G4 levels and Graves' disease phenotype.

PURPOSE: We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. METHODS: This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. RESULTS: In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p < 0.001), had higher antithyroid peroxidase antibody (p = 0.01), and anti-thyroglobulin antibody levels (p = 0.006) and required shorter duration of the first methimazole treatment cycle (p = 0.041) than patients with immunoglobulin G4 below the 75th percentile. At diagnosis, patients with immunoglobulin G4 levels above the 90th percentile (>286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. CONCLUSIONS: Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

Cerebral arteriopathy with subcortical infarcts and leukoencephalopathy in acromegalic patient with severe headache.

A 68-year-old female patient was admitted in our clinic with severe frontal bilateral headache, dizziness, depression and cognitive decline in the context of a previously diagnosed acromegaly. She also had high blood pressure, dyslipidemia, secondary diabetes mellitus. Acromegaly was caused by a growth hormone (GH) secreting-pituitary macroadenoma, so a transsphenoidal surgery was performed. The postoperative magnetic resonance imaging (MRI) scan revealed a 20÷22÷25 mm pituitary mass remnant and medical therapy with somatostatin analogues (SSAs) was started. After nine months of treatment with SSAs, she continued having severe headache, the blood pressure was well controlled, but GH secretion was only partially controlled with insulin-like growth factor-1 (IGF-1) level still above the normal value. The MRI scan showed the same pituitary tumor remnant with supra- and parasellar right extension and also multiple fronto-temporo-parietal subcortical lesions that could suggest in the clinical context cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). According to a pregenetic screening tool, the Pescini Scale, the patient had a 19 points score, which is highly suggestive for CADASIL, an inherited cerebrovascular disease due to mutations of the Notch3 gene at the chromosome locus 19p13. In the absence of genetic testing, an alternate way to prove small vessels disease, the skin biopsy, was performed. Electron microscopy showed granular osmiophilic material (GOM) surrounding the vascular smooth muscle cells on that are pathognomonic for the disease. Our report underscores the importance of repeated investigations even in patients with apparently obvious explanations of their condition since they may have multiple diseases with the same presenting clinical signs.

Stunted Growth. Proceedings of the 23rd Aschauer Soiree, Held at Aschauhof, Germany, November 7th 2015.

Twenty-four scientists met at Aschauhof, Altenhof, Germany, to discuss the associations between child growth and development, and nutrition, health, environment and psychology. Meta-analyses of body height, height variability and household inequality, in historic and modern growth studies published since 1794, highlighting the enormously flexible patterns of child and adolescent height and weight increments throughout history which do not only depend on genetics, prenatal development, nutrition, health, and economic circumstances, but reflect social interactions. A Quality of Life in Short Stature Youth Questionnaire was presented to cross-culturally assess health-related quality of life in children. Changes of child body proportions in recent history, the relation between height and longevity in historic Dutch samples and also measures of body height in skeletal remains belonged to the topics of this meeting. Bayesian approaches and Monte Carlo simulations offer new statistical tools for the study of human growth.

Overweight and Underweight Prevalence Trends in Children from Romania - Pooled Analysis of Cross-Sectional Studies between 2006 and 2015.

AIM: High-quality national representative data on obesity in Romanian children are needed to shape public health policies. To provide a unified data landscape on national prevalence, trends and other factors associated with underweight, overweight, and obesity in Romanian children aged 6-19 years, across the last decade (2006-2015). METHODS: Using a common protocol, we selected published and unpublished studies that measured Romanian children in schools between 2006 and 2015. Children's BMI was classified using the current WHO, IOTF, and CDC references. RESULTS: 25,060 children from 8 Romanian counties were included in the analysis. The prevalence of underweight children was 5%/4.5%/8.5% (WHO/IOTF/CDC), while the prevalence of overweight (including obese) children was 28.3%/23%/23.2% (WHO/IOTF/CDC). The prevalence of overweight children did not change significantly over the last decade (chi-square test p = 0.6). Male gender (odds ratio (OR) 1.37; 95% CI 1.29-1.45, compared to female); prepubertal age (OR = 3.86; 95% CI 3.41-4.36,compared to postpubertal age), and urban environment (OR 1.12; 95% CI 1.01-1.26, compared to rural environment) had higher risk for overweight. CONCLUSION: While the prevalence of underweight children was low, almost one in four children in Romania was overweight or obese (according to WHO criteria) between 2006 and 2015. This prevalence remained relatively stable over the last decade. Male gender, prepubertal age, and urban environment, were the most relevant risk factors associated with overweight status in Romanian children.

IGF-1 and Insulin Resistance Are Major Determinants of Common Carotid Artery Thickness in Morbidly Obese Young Patients.

We assessed the relationship between insulin resistance, serum insulin-like growth factor 1 (IGF-1) levels, and common carotid intima-media thickness (CC-IMT) in morbidly obese young patients. A total of 249 patients (aged 37.9 ± 9.8 years, body mass index [BMI] 45.6 ± 8.3 kg/m(2)) were evaluated (metabolic tests, serum IGF-1 measurements, homeostasis model assessment-insulin resistance [HOMA-IR], and ultrasonographically assessed CC-IMT) in a research program for bariatric surgery candidates. After adjusting for age, gender, BMI, systolic blood pressure, uric acid, antihypertensive and lipid-lowering treatment, metabolic syndrome, and metabolic class, both HOMA-IR and IGF-1 z-score were significantly associated with CC-IMT. These results were confirmed in logistic regression analysis, in which age (ß = 1.11, P = .001), gender (ß = 3.19, P = .001), HOMA-IR (ß = 1.221, P = .005), and IGF-1 z-score (ß = 1.734, P = .009) were the only independent determinants of abnormal CC-IMT, presumably modulating the effect of the other risk factors included in the regression. Area under the receiver-operating characteristic curve for the model was 0.841 (confidence interval: 0.776-0.907; P < .001). In conclusion, in morbidly obese young adults, insulin resistance and IGF-1 z-score are significantly associated with CC-IMT, independent of other major cardiovascular risk factors.

Papillary thyroid carcinoma with anaplastic dedifferentiation in the lymph node metastasis - a rare form of presentation even for a tall cell variant.

Papillary thyroid carcinoma (PTC) is well known as a differentiated thyroid carcinoma with an established treatment protocol and high survival rates. Nevertheless, its tall cell variant (TCV) is more frequent diagnosed with larger tumor size, advanced age and metastasis comparing to other PTC cases, resembling an increased level of aggressiveness attributable to the histological subtype according to recent studies. We present the case of a 60-year-old woman who came for a recently increase of the thyroid and a left laterocervical mass associated with pain and alteration of general status. Thyroidectomy revealed a TCV of PTC with infiltration of the extrathyroid tissue. The laterocervical mass posed difficulties to surgical excision but in a second attempt proved to be an undifferentiated carcinoma. The findings were associated to a rapid deterioration of the patient's general condition finalized with death within less than three months from the initial presentation.

IGF1 deficiency in newly diagnosed Graves' disease patients.

OBJECTIVE: Thyroid hormones influence the GH/IGF1 axis, but previous studies have reported discrepant results regarding serum IGF1 levels in hyperthyroidism. We have therefore investigated, at diagnosis, the relationship between serum IGF1 levels and the main characteristics of Graves' disease (GD): severity of hyperthyroidism, goiter size, presence of active Graves' ophthalmopathy (GO), antythyroid antibodies status and titer. DESIGN AND METHODS: This cross-sectional study included 98 newly diagnosed hyperthyroid patients with GD who presented consecutively at our clinic. The main measured parameters were: TSH, FT4, FT3, TT3, thyroglobulin,anti-thyroid peroxidase antibodies (TPOAb), anti-thyroglobulin antibodies (ATA), thyrotropin receptor antibodies (TRAb), IGF1. Patients were considered IGF deficient if IGF1 z score was ≤-2SD from mean for age. RESULTS: In GD patients, men had higher IGF1 levels (p=0.023) and IGF1 z scores (p=0.013) than women. 18.4% of GD patients were, at diagnosis, IGF1 deficient. Compared to patients without IGF1 deficiency, these patients presented higher thyroglobulin (median=72.55, IQR=116.02 vs median=11.40, IQR=80.74 ng/ml, p=0.002) and FT3 (median=11.30, IQR=7.64 vs median=7.33, IQR=5.72 pg/ml, p=0.027), and lower ATA (median=20, IQR=0 vs median=34.05, IQR=161 iu/ml, p<0.001) levels. Thyroglobulin was independently associated with IGF1 deficiency (AUROC=0.732, 95% CI: 0.620-0.844, p=0.002; cut-off for thyroglobulin=50.40 ng/ml, Se=77.8%, Sp=70%). IGF1 status was not influenced by gender (p=0.084), current smoking (p=0.558), goiter size (p=0.533), active ophthalmopathy (p=0.334), TRAb (p=0.239) or TPOAb status (p=0.367). CONCLUSIONS: Nearly one fifth of newly diagnosed GD patients had IGF1 deficiency. IGF1 deficiency was associated with lower ATA titers, higher thyroglobulin levels and more severe FT3 hyperthyroidism at diagnosis.

Obesity and eating behaviors in school children and adolescents -data from a cross sectional study from Bucharest, Romania.

BACKGROUND: Epidemiological data on obesity prevalence are scarce in Romanian population. Consequently, the aim of our study was to evaluate the prevalence of obesity and unhealthy behaviors among school children and adolescents from Bucharest, Romania. METHODS: Cross-sectional study, 866 participants (53.2% girls, 46.8% boys, age range 6-18 years), selected by systematic sampling with probability-proportionate-to-size from all Bucharest's schools. MEASUREMENTS: height, weight and a questionnaire to collect information about life style and eating behavior. Nutritional status was established based on World Health Organization recommendations (WHO), International Obesity Task Force (IOTF), Center for Diseases Control (USA-CDC) cut off values and local standards, respective. RESULTS: The prevalence of overweight (including obese) and obesity alone based on different standards, was 31.6% and 11.4% (WHO), 24.6% and 6.2% respectively (IOTF), 25.2% and 10% (USA-CDC), 22.3% and 12.5% (local standards). When using local standards (weight only based), the obese subjects proportion among overweight children raised questions regarding the appropriateness of these standards. Overweight (including obese) prevalence was significantly higher among the boys versus girls: 36.2% vs. 27.6%, ( OR 1.5; 95% CI 1.12-2.03; p value = 0.006) and among the 6-10.9 years vs. 11-17.9 age group, (40.7% vs 26.6%). Almost all the participants (95%) reported at list one unhealthy eating behavior but no significant relationship was found with overweight or obesity only. CONCLUSIONS: This first epidemiological study of obesity prevalence in school children and adolescents showed that 11.4% of Bucharest's children and adolescents were obese by WHO classification, 6.1% by IOTF cut off values and 10% by CDC classification. Younger children and the boys were more affected no matter which standard we used. In spite of unsignificant relationship to the adiposity status, our data showed a high prevalence of unhealthy eating behaviors reported by the participants. Particular aspects of the overweight versus obesity prevalence, after applying local standards, suggests that international recognized algorithms should be used for constant epidemiological evaluation instead of establishing local criteria.

Biochemical hyperandrogenism is associated with metabolic syndrome independently of adiposity and insulin resistance in Romanian polycystic ovary syndrome patients.

The aim of the study was to determine whether Romanian polycystic ovary syndrome (PCOS) patients have an increased prevalence of metabolic syndrome (MetS) and to study the involvement of adiposity, insulin resistance and hyperandrogenism in the pathogenesis of MetS in PCOS. A total of 398 PCOS patients and 126 controls were evaluated between January 2006 and December 2012. MetS was defined by National Cholesterol Education Program, Adult Treatment Panel III criteria. Principal component analysis (PCA) was used to analyze the correlations among variables of interest by grouping them in few components, and principal component (PCs) scores were saved and used as independent variables in logistic regression. The prevalence of MetS was higher among patients with PCOS (20.4 %) than in controls (11.1 %, p < 0.05). In PCOS patients, PCA extracted three PCs from the analyzed variables. First PC aggregated variables related to adiposity and insulin resistance, with factor loadings showing strong relationship between these parameters. The second PC included markers of hyperandrogenemia and was best represented by free androgen index (FAI) which correlated strongly and exclusively with this PC. The third component was best represented by hirsutism. Logistic regression analysis revealed that in PCOS patients, the first and the second PCs were independently associated with MetS, whereas the third component was not. Romanian PCOS patients have an increased risk for MetS; adiposity, insulin resistance and hyperandrogenemia, but not hirsutism, are independent predictors of MetS presence. Our data also suggest that insulin resistance is only secondary to increased adiposity and FAI is a good marker of biochemical hyperandrogenism with little influences from the metabolic component.

Risk factors associated with hypogonadism in ß-thalassemia major patients: predictors for a frequent complication of a rare disease.

BACKGROUND: ß-Thalassemia major (BTM) is a rare disease that challenges clinicians because of the high prevalence of complications despite progress in the development of new therapeutic methods. The aim of this study was to identify clinical and hematological parameters associated with hypogonadism, the most frequent iron overload-related complication found in Romanian patients. METHODS: Patients with BTM were evaluated in the Endocrinology Department of Elias Hospital between February 2004 and December 2013. Only patients who provided written informed consent were included in the study. A complete physical and hormonal evaluation was performed on all patients, and data regarding treatment of the hematological disease were collected. RESULTS: Of the evaluable patients, 85 were included in the study (median age, 21[10] years; range, 13-36 years). We found that 30.6% of the study participants (26 of 85) had normal gonadal status, 54.1% (46 of 85) had early forms of hypogonadism (delayed or arrested puberty), and 15.3% (n = 13) developed hypogonadism after complete sexual maturation. Patients with any form of hypogonadism were older (median age 22 vs 16.5 years, P = 0.047), had significantly lower average hemoglobin levels (P = 0.003), and had higher levels of serum ferritin (P = 0.006) versus patients without hypogonadism. Patients with delayed puberty were associated with increased average serum ferritin levels (P = 0.007), decreased hemoglobin levels (P = 0.001), and increased age at initiation of iron chelation therapy (P < 0.01). We found no significant differences between patients with early forms of hypogonadism and those with hypogonadism after complete sexual maturation, with respect to the analyzed parameters. Patients with adult hypogonadism were significantly older (median age 26 vs 16.5 years, P = 0.007) and tended to have higher serum ferritin levels (P = 0.056) compared with patients without hypogonadism. CONCLUSION: Our data show that hypogonadism is highly prevalent among Romanian patients with BTM, its presence being associated with higher iron overload and lower hemoglobin values. The late start of iron chelation therapy was particularly associated with pubertal abnormalities.
