Abstract
OBJECTIVES Thyroid hormones have important roles in normal development and energy regulating mechanisms as well as signaling mechanisms that affect energy consumption through central and peripheral pathways. The aim of this study was to determine the effects of thyroid dysfunction on adropin, asprosin and preptin levels in rat. METHODS The study was performed on the 38 male Wistar-albino rats. Experiment groups were designed as follows. 1-Control, 2-Hypothyroidism; To induce hypothyroidism PTU was applied by intraperitoneal as 10 mg/kg/day for 2 weeks. 3-Hypothyroidism + Thyroxine; Previously animals were made with hypothyroidism by 1 week PTU application and then 1 week l-thyroxine was given by intraperitoneal as 1.5 mg/kg/day. 4-Hyperthyroidism; Rats were made with hyperthyroidism by 3 weeks l-thyroxine (0.3 mg/kg/day). 5-Hyperthyroidism + PTU; Animals were made hyperthyroisim by l-thyroxine as groups 4, then 1 week PTU was applied to treatment of hiperthyrodism. At the end of supplementation animals were sacrificed and blood samples were collected for FT3, FT4, adropin, asprosin, preptin analysis. RESULTS FT3 ve FT4 levels were reduced significantly in hypothyroidism while increased in hyperthyroidism (p<0.001). Hipothyrodism led to reduces adropin, asprosin and preptin levels. And also hyperthyroidism reduced adropin and preptin levels (p<0.001). CONCLUSIONS The results of study show that experimental hypothyroidism and hyperthyroidism lead to significantly change to adropin, asprosin and preptin levels. However, correction of thyroid function caused to normals levels in asprosin and preptin.

Abstract
Introduction The increasing knowledge of adropin, afamin, and neudesin and the regulation of glucose metabolism and insulin resistance allows for the assessment of the differences in their concentrations between the groups with varied duration of diabetes mellitus (DM). Aim of the Study Assessment of serum levels of adropin, afamin, and neudesin in children with type 1 diabetes, with respect to the disease duration. Materials and Methods The study consisted of 138 patients aged 5–18 years (M 40.58%). Children with type 1 diabetes (n = 68) were compared to the control group (n = 70). The diabetic group was divided into 4 subgroups: (I) newly diagnosed patients, after an episode of ketoacidosis (n = 14), (II) duration no longer than 5 years (n = 18), (III) 5 to 10 years (n = 27), and (IV) longer than 10 years (n = 9). Serum concentrations of adropin, afamin, and neudesin were assessed and compared between the groups of patients. The criterion for statistical significance was p < 0.05. Results The concentrations of adropin and afamin across all subgroups were lower than that in the control group, while neudesin levels were higher in diabetic patients compared to the control group. The differences were statistically significant. Conclusions Adropin, afamin, and neudesin may play a major role in the regulation of glucose metabolism and have a significant potential as novel biomarkers to predict future metabolic disorders. However, further multicentre studies on a larger cohort of patients are necessary to specify the role of these substances in the course and treatment of type 1 diabetes.

Abstract
RATIONALE Simpson-Golabi-Behmel syndrome type 1 (SGBS1) is caused by mutations in GPC3 or in both GPC3 and GPC4. Physical manifestations of SGBS1 include fetal overgrowth and macrostomia, macroglossia. Subclinical hypothyroidism has never been reported in SGBS1 cases. PATIENT CONCERNS An 8-days-old boy was referred to our hospital with persistent hypoglycemia and special facies. And the infant showed elevated levels of thyroid-stimulating hormone (TSH). Free T4 and free T3 were normal. DIAGNOSES Definitive diagnosis of SGBS1 depends on clinical features and genetic testing. A nonsense mutation (c.1515C > A, p. Cys505*) was tested by whole-exome sequencing. INTERVENTIONS Normal blood glucose levels were maintained with glucose infusions. Levothyroxine was given to the patient for treating subclinical hypothyroidism. OUTCOMES The parents decided to abandon the treatment of the patient. We learned that the patient died of a lung infection by a telephone follow-up. LESSONS Subclinical hypothyroidism could be added to the known clinical manifestations of SGBS1.

Abstract
Ghrelin is a peptide hormone produced mainly in the gastrointestinal tract known to regulate several physiological functions including gut motility, adipose tissue accumulation and hunger sensation leading to increased bodyweight. Studies have found a correlation between the plasma levels of thyroid hormones and ghrelin, but an effect of ghrelin on the human thyroid has never been investigated even though ghrelin receptors are present in the thyroid. The present study shows a ghrelin-induced decrease in the thyroid-stimulating hormone (TSH)-induced production of thyroglobulin and mRNA expression of thyroperoxidase in a primary culture of human thyroid cells obtained from paranodular tissue. Accordingly, a trend was noted for an inhibition of TSH-stimulated expression of the sodium-iodine symporter and the TSH-receptor. Thus, this study suggests an effect of ghrelin on human thyrocytes and thereby emphasizes the relevance of examining whether ghrelin also influences the metabolic homeostasis through altered thyroid hormone production.

Abstract
Subclinical hypothyroidism is defined as serum levels of TSH above the upper limit of the reference range, in the presence of normal concentrations of total T4 or free T4. This biochemical profile might be an indication of mild hypothyroidism, with a potential increased risk of metabolic abnormalities and cardiovascular disease recorded among adults. Whether subclinical hypothyroidism results in adverse health outcomes among children is a matter of debate and so management of this condition remains challenging. Mild forms of untreated subclinical hypothyroidism do not seem to be associated with impairments in growth, bone health or neurocognitive outcome. However, ongoing scientific investigations have highlighted the presence of subtle proatherogenic abnormalities among children with modest elevations in their TSH levels. Although current findings are insufficient to recommend levothyroxine treatment for all children with mild asymptomatic forms of subclinical hypothyroidism, they highlight the potential need for assessment of cardiovascular risk among children with this condition. Increased understanding of the early metabolic risk factors associated with subclinical hypothyroidism in childhood will help to improve the management of affected individuals.

Abstract
The increasing knowledge on the functions of gastric peptides and adipokines in the body allows the assumption of their major role linking the process of food intake, nutritional status, and body growth, largely through the regulation of glucose metabolism and insulin resistance. The aim of the study was the assessment of serum levels of selected gastric peptides and adipocytokines in children with type 1 diabetes, with respect to the disease duration. The study involved 80 children aged 4-18 years (M/F -37/43). Children with type 1 diabetes (n = 46) were compared to the control group (n = 34). The study group was divided into 4 subgroups: (I) patients with newly diagnosed type 1 diabetes, after an episode of ketoacidosis (n = 10), (II) patients with type 1 diabetes of duration no longer than 5 years (n = 9), (III) patients with 5 to 10 years of DT1 (n = 20), and (IV) patients with type 1 diabetes of duration longer than 10 years (n = 7). The concentrations of gastric peptide and adipocytokines across all subgroups were lower than in the control group. The differences were statistically significant (p < 0.0001), which may be of importance in the development of the disease complications.

Abstract
BACKGROUND A potential role of preproghrelin polymorphisms on autoimmune thyroid diseases (AITDs) has not been established equivocally yet. AIM To estimate the association of two polymorphisms of preproghrelin gene with the predisposition to Graves' disease (GD) and Hashimoto's thyroiditis (HT) in children. METHODS The study was performed in 145 patients with GD, 87 with HT and 161 healthy volunteers. The two single nucleotide polymorphisms (SNPs) rs696217 (C_3151003_20) and rs4684677 (C_25607748_10) in the preproghrelin gene were genotyped by TaqMan SNP genotyping assay using the real-time PCR. RESULTS Rs4684677 T alleles were more frequent in HT patients (99% in women and 100% in men) in comparison to healthy subjects (p = 0.002) with OR = 8.0 and 95% confidence interval for OR: 1.8-206.7. In women group, rs4684677 T alleles were more frequent compared to healthy controls (99%) in HT (p = 0.02) with OR = 6.7 and 95% confidence interval for OR: 1.2-168.37. Frequency of the SNP rs696217 did not differ between the groups. There was a significant relationship between rs696217 polymorphisms and anti-TSHR antibodies level (p = 0.036) in women from GD/HT groups. A significant relationship between rs696217 polymorphisms and anti-TG antibodies level in GD women group (p = 0.038) and between rs696217 polymorphisms and fT4 concentration (p = 0.03) were found. CONCLUSIONS Rs4684677 T/A polymorphisms in preproghrelin gene could contribute to development of AITDs in children and T allele is the main risk factor.

Abstract
Thyroid hormones are crucial hormones that primarily regulate the metabolism of entire body cells. In this study, Sprague-Dawley rats were grouped into sham thyroidectomy (Sham Tx), thyroidectomy (Tx), Tx with thyroxine replacement (Tx + T4), and PTU injection (PTU) groups. Metabolic parameters were measured by means of metabolic cages for 14 days. After 14 days, the rats were sacrificed while the levels of plasma or serum TSH and growth-related molecules, such as active and total ghrelin, GH, and IGF-1, were assayed. The results revealed that hypothyroid rats tended to eat less food and experienced substantial body weight gain, whereas the rats with T4 replacement tended to eat more food while continuing to lose weight. In hypothyroid rats, the growth-related molecules, such as active ghrelin and total ghrelin secretion, were enhanced, and the ghrelin receptors were also up-regulated. However, circulating GH levels were not elevated and IGF-1 secretion was inhibited in hypothyroid rats. In the Tx + T4 group, the changes of active ghrelin, total ghrelin, GHS-R expression, and IGF-1 were reversed, whereas the GH secretion was higher than that of the Sham Tx group and hypothyroid groups. This study resulted in the novel finding that the ghrelin/GHS-R axis and GH/IGF-1 axis are interrupted in hypothyroid rats.

ACTA ACUST UNITED AC 2014; 189:17-21. [PMID: 24508278 DOI: 10.1016/j.regpep.2014.01.001] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2013] [Revised: 01/10/2014] [Accepted: 01/11/2014] [Indexed: 10/25/2022]
Abstract
BACKGROUND Ghrelin and obestatin are important appetite- and energy-regulating peptides, secreted by the stomach. These gut peptides and thyroid hormones are involved in metabolism regulation. Although subclinical thyroidism is common, to date, very few studies have been reported about gut hormones in thyroid dysfunction, and their results are controversial. The purpose of this study was to investigate ghrelin and obestatin in patients with subclinical hypo- and hyperthyroidism. Moreover, is association between thyroid hormones and gut peptides able to suggest new regulatory relation between the HPT axis and gut? MATERIALS AND METHODS The study group included 70 subclinical hypo- and hyperthyroid subjects (in equal groups) and 35 healthy euthyroid controls. Serum values of ghrelin, obestatin, free T3, free T4, thyroid-stimulating hormone and the ratio of ghrelin to obestatin were measured in all participants. RESULTS Ghrelin and obestatin both decreased in subclinical hypothyroid subjects (320±81ng/l and 44.3±11.7ng/l, respectively) compared to the control group (487±110ng/l and 58.5±10.3ng/l, respectively). On the other hand, ghrelin and obestatin both increased in subclinical hyperthyroid subjects (750±289ng/l and 71.1±27.3ng/l, respectively) compared to the control group. In addition, ghrelin and obestatin showed strong correlations with TSH, FT3 and FT4. CONCLUSION This study shows that gut hormones are significantly associated with thyroid hormones. Thus, there may be a cross talk between the HPT axis and gut. We would like to consider new regulatory relation for description of the found data.

Abstract
AIMS Thyroid dysfunction is frequently observed in patients with type 2 diabetes mellitus (T2DM), but the underlying mechanism is still poorly understood. The present study aimed to investigate whether nesfatin-1 played a role in the thyroid dysfunction in patients with T2DM. METHODS 55 euthyroid patients were enrolled in this study including 30 patients with T2DM and 25 patients with impaired glucose regulation (IGR). 30 age-matched healthy people were also included as the control. The plasma levels of nesfatin-1, thyrotropin (TSH), and glycosylated hemoglobin (HbA1c) as well as the body mass index (BMI) were comparatively analyzed among the three groups. RESULTS The nesfatin-1 was significantly lower in patients with T2DM than in patients with IGR and in the control. On the contrary, the TSH level was significantly higher in patients with T2DM than in patients with IGR and in the control. Simple regression analysis showed that the plasma nesfatin-1 was negatively correlated with the TSH and HbA1c levels and positively correlated with the BMI. With multiple stepwise regression analysis, the nesfatin-1 remained to be independently correlated with the TSH, BMI, and HbA1c. CONCLUSIONS The study was suggesting a role of nesfatin-1 in thyroid dysfunction in patients with T2DM.

Abstract
The preproghrelin gene is responsible for generating ghrelin and obestatin, two gastric peptides with opposite effects on food intake. Obestatin suppresses food intake and digestive motility through interaction with GPR39 (GPCR). Ghrelin is supposed to be a link connecting metabolism and energy homeostasis with growth as the result of activation of the growth hormone secretagogue receptor (GHSR).The aim of the current study was to assess the expression of preproghrelin, GPR39 and GHSR in thyroid tissues from patients with Graves' disease (GD; n = 15), non-toxic nodular goiter (NTNG; n = 10) and toxic nodular goiter (TNG; n = 10). GPR39 and GHSR in thyroid tissues were detected by immunohistochemistry and Western blot, revealing higher expression of both proteins in GD patients (+++; ++) in comparison with NTNG (+; +) and TNG (++; +) patients. GPR39 was present in thyroid autoimmune disease, NTNG and TNG at band p51 (kDa). The ghrelin receptor was identified in all study groups at p70. mRNA expression for preproghrelin was found in thyroid tissues from patients with immune and non-immune thyroid diseases. We conclude that the expression of the ghrelin receptor family in thyroid tissues may suggest a role of gastric peptides in thyroid functions. mRNA of preproghrelin expression is a proof of ghrelin gene-derived peptide presence in thyroid tissues.

AIM To investigate the influence of overt hyperthyroidism and euthyroid congenital hypothyroidism on fasting glucagon-like peptide-1 (GLP-1) levels. METHODS A total of 30 untreated overt hyperthyroidism patients, 17 euthyroid congenital hypothyroidism children, and age- and sex-matched controls were enrolled. Levels of GLP-1, insulin, glucose, and homeostasis model assessment (HOMA-IR) were measured and evaluated. RESULTS Fasting GLP-1, blood glucose, insulin, and HOMR-IR levels were higher in patients with overt hyperthyroidism than in controls (p=0.030, p=0.008, p=0.004, p=0.037, respectively). These parameters in euthyroid hypothyroidism were similar to the controls. In euthyroid congenital hypothyroidism and overt hyperthyroidism patients, serum GLP-1 levels were not correlated with thyroid hormone, blood glucose, insulin, and HOMR-IR. CONCLUSIONS Fasting GLP-1 levels in the peripheral circulation were significantly increased in overt hyperthyroidism, however, they were no different in euthyroid congenital hypothyroidism.

Abstract
Ghrelin shows orexigenic effect through its action on the hypothalamic appetite-regulating pathways, while in the periphery ghrelin increases adipose tissue accumulation and has a diabetogenic effect on the liver and pancreas. Adenosine monophosphate-activated protein kinase (AMPK) has been suggested as one of the mediators of ghrelin's effects. Plasma ghrelin levels are dependent on body mass index as well as food intake patterns. Ghrelin levels are in general reduced in obese individuals and in subjects with insulin resistance. In contrast to other forms of obesity, patients with Prader-Willi syndrome (PWS) display high levels of ghrelin, reduced visceral adiposity and relative hypoinsulinemia. Relationships between obesity and common genomic variants of GHRL and GHS-R genes have been studied. Ghrelin may have a role in the weight-reducing effect of bariatric surgery; however, this is a much debated issue. Altered ghrelin levels have also been observed in Cushing's syndrome and thyroid disease probably due to the secondary insulin resistance in these subjects.
