Insights

Isolated hyperthyrotropinemia (IH) is more common in obese children. In these children, thyroid-stimulating hormone (TSH) levels positively correlate with BMI-SDS and triglycerides, and negatively with free T4.

Area of Science:

  • Pediatric Endocrinology
  • Metabolic Disorders
  • Thyroid Function

Background:

  • Obesity is a growing global health concern in children.
  • Thyroid dysfunction, including isolated hyperthyrotropinemia (IH), may be associated with obesity.
  • Understanding these associations is crucial for pediatric health management.

Purpose of the Study:

  • To determine the prevalence of IH in obese children.
  • To investigate the relationship between IH and anthropometric/metabolic parameters in obese children.

Main Methods:

  • Retrospective review of hospital records for obese children and matched healthy controls.
  • Analysis of thyroid function tests, including thyroid-stimulating hormone (TSH) and free T4 (fT4).
  • Correlation and regression analyses to assess relationships between TSH, BMI-SDS, and lipid profiles.

Main Results:

  • IH prevalence was significantly higher in obese children (9.2%) compared to controls (3.8%).
  • Obese children showed significant differences in BMI-SDS, TSH, and lipid parameters versus controls.
  • TSH positively correlated with BMI-SDS and triglycerides, and negatively with fT4 in obese subjects.

Conclusions:

  • Obese children exhibit a higher prevalence of isolated hyperthyrotropinemia.
  • TSH levels in obese children are influenced by BMI-SDS, triglyceride levels, and fT4 levels.

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH...

Obesity

The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in...

Hypothyroidism II: Pathophysiology01:23

Hypothyroidism II: Pathophysiology

Hypothyroidism is a disorder characterized by insufficient production of thyroid hormones, which regulate metabolism, energy balance, and multiple organ systems.TypesHypothyroidism is classified based on the level of dysfunction. Primary hypothyroidism results from intrinsic thyroid gland dysfunction, causing reduced hormone production despite normal or increased stimulation. Secondary hypothyroidism arises from inadequate thyroid-stimulating hormone (TSH) secretion by the pituitary. Tertiary...

Type II Diabetes I: Introduction01:26

Type II Diabetes I: Introduction

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterized by insulin resistance, in which target tissues such as the liver, muscle, and adipose tissue respond poorly to insulin. It is also associated with inadequate compensatory insulin secretion, where pancreatic β-cells fail to produce sufficient insulin. Together, these abnormalities lead to persistent hyperglycemia.EtiologyT2DM develops through a complex interaction of genetic predisposition and environmental or...

Graves Disease II: Pathophysiology01:24

Graves Disease II: Pathophysiology

Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor,...
