[Serum thyrocalcitonin and parathyroid hormone content in children with diffuse toxic goiter and hypothyroidism]
Insights
Thyrocalcitonin (TCT) levels remain stable in children with thyroid disorders, while parathyroid hormone (PH) decreases in thyrotoxicosis. These hormones do not significantly impact bone or mineral metabolism in pediatric thyroid disease.
Area of Science:
- Pediatric Endocrinology
- Endocrinology
- Clinical Chemistry
Background:
- Thyroid diseases, including diffuse toxic goitre (thyrotoxicosis) and hypothyrosis, are common in children.
- Thyrocalcitonin (TCT) and parathyroid hormone (PH) play crucial roles in calcium and bone metabolism.
- Understanding their role in pediatric thyroid conditions is essential for managing potential complications.
Purpose of the Study:
- To investigate the blood levels of TCT and PH in children diagnosed with diffuse toxic goitre and hypothyrosis.
- To determine the relationship between TCT and PH levels and the pathogenesis of bone injuries and mineral metabolism changes in these pediatric thyroid diseases.
Main Methods:
- Radioimmunoassay (RIA) was employed to quantify blood plasma concentrations of TCT and PH.
- The study included cohorts of children with thyrotoxicosis (n=20 for TCT, n=18 for PH) and hypothyrosis (n=28 for TCT, n=20 for PH).
Main Results:
- Blood plasma TCT concentrations showed no significant alterations in children with either diffuse toxic goitre or hypothyrosis.
- Parathyroid hormone (PH) levels were found to decrease in patients with thyrotoxicosis.
- A wide variability in individual PH values was observed in children with hyperthyroidism.
Conclusions:
- Blood TCT concentration is not a significant factor in the pathogenesis of bone injuries or mineral metabolism changes in pediatric thyroid diseases.
- Decreased PH levels and their wide variability in hyperthyroid children suggest a potential role, though not essential, in disease pathogenesis.
- Neither TCT nor PH appear to have essential significance in the pathogenesis of bone injuries and mineral metabolism changes in children with thyroid diseases.
Abstract:
Radioimmunoassay was used to study the blood thyrocalcitonin (TCT) and parathyroid hormone (PH) content in children with diffuse toxic goitre and hypothyrosis. The blood plasma TCT content was determined in 20 children with thyrotoxicosis and in 28 subjects with hypothyrosis. PH content was examined correspondingly in 18 and 20 patients. It was concluded that the blood TCT concentration is not significantly changed in children suffering from diffuse toxic goitre and hypothyrosis. PH content decreases in patients with thyrotoxicosis. Wide variability of PH individual values is peculiar to hyperthyrosis. TCT and PH have no essential significance in the pathogenesis of bone injuries and mineral metabolism changes in thyroid diseases of children.
