Abstract:

Introduction: Leptin and Ghrelin are hormones that have been discovered in the last decade and were shown to be involved in appetite and metabolism regulation and body weight. Thyroid hormones are also    involved in general metabolism and changes in their circulating levels bring about changes in appetite and body weight. Results of animal and human studies regarding Leptinlevel and its relation to thyroid hormones are opposing each other, and there is no data about Ghrelin level in thyroid malfunction. To determine the relation between thyroid function and circulating levels of Ghrelin and Leptin, we evaluated serum concentration of these hormones in patients with untreated thyroid malfunction. Method: Thirty hyperthyroid and 30 hypothyroid females that were aged between 14-52 years and 30 healthy females with the same age range (control group) were randomly selected. From each participant 5 ml of fasting blood was collected and after processing, serum levels of T4, T3, T3-uptake, TSH, Leptin and Ghrelin were evaluated by radio-immunoassay or enzyme-link immunoassay methods. Results: Evaluated results showed that neither Ghrelin nor Leptin levels show significant change in patients with thyroid malfunction. But there was a positive significant correlation between Leptin level and BMI of all participants (r=0.41, P<0.01). In addition, there were negative significant correlations between Ghrelin and thyroid hormones (r=0.27, P<0.05). Conclusion: The present results show that Leptin variation is due to BMI. Furthermore, negative and weak correlation between thyroid hormones and Ghrelin may indicate that increase in appetite of hyperthyroid patients and its decrease in hypothyroid patients are not due to circulating level of Ghrelin

Evaluation of thyroid gland dysfunction in patients with alopecia areate

Introduction: Alopecia areata is a common clinical problem involving 1% of population. It is associated with many autoimmune disorders. One of the most common associations is autoimmune thyroid disease. So it seems necessary to examine the patients with alopecia areata more exactly. The main purpose of this study was to evaluate thyroid gland dysfunction in patients with alopecia areata. Mate...

Evaluation of thyroid hormones in patients with lead poisoning

Background: Each toxic agent results in unique presentations, depending on what neurophysiological changes occur following exposure. Scientific understanding of lead toxicity in the organ systems and at low levels of exposure continues to evolve. However, effects of lead poisoning on the thyroid gland function are controversial. In this descriptive study, changes in thyroid hormones in patients...

Ghrelin, Resistin and Leptin Levels in Patients with Metabolic Syndrome

Aim: This study was designed to compare the fasting ghrelin, leptin and resistin levels between metabolic syndrome (MS) patients with healthy controls. Method: This trial was performed on 21 patients with MS (7 men; mean age, 44±4 years) and 17 healthy controls (8 men; mean age, 43±3 years). Diagnosis of MS was defined based on National Cholesterol Education Program (NCEP) Adult Treatment Panel...
