Aims: Hypothyroidism is a common side effect of radiotherapy for nasopharyngeal carcinoma. However, the impact of thyroid hormone replacement therapy on patients with radiation-induced subclinical hypothyroidism has not been extensively explored. This study aimed to analyze the efficacy of thyroid hormone replacement therapy in nasopharyngeal carcinoma patients with subclinical hypothyroidism.

Methods: Patients diagnosed with nasopharyngeal carcinoma who developed subclinical hypothyroidism after definitive radiotherapy between September 2019 and December 2020 were selected for inclusion in this study. Prior to thyroid hormone replacement therapy and after maintaining euthyroidism for 6-12 months through thyroid hormone replacement therapy, assessments using the SF36 Brief Health Status Scale and the Hypothyroidism-related Symptom Questionnaire were conducted via trained questionnaires. Lipid profiles were assessed at baseline and after 6-12 months of thyroid hormone replacement therapy. Statistical analyses were performed using matched samples T-test or Mann-Whitney U test.

Results: The median follow-up period was 14.5 months. The median score of hypothyroid symptoms was 5.5 out of 19 points, with the most common symptoms being chills (65.0%), fatigue (50.0%), weight gain (45.0%), and limb numbness (40.0%). Thyroid hormone replacement therapy did not significantly improve the quality of life, hypothyroidism-related symptoms, or blood lipid profile in patients. However, there was an observed downward trend in serum cholesterol levels following treatment (P=0.052).

Conclusion: Thyroid hormone replacement therapy did not have a significant impact on alleviating hypothyroid symptoms, improving quality of life, or enhancing lipid profiles in patients with radiation-induced subclinical hypothyroidism. Nevertheless, a potential decrease in serum cholesterol levels was noted after thyroid hormone replacement therapy.

Objectives: Exocrine pancreatic insufficiency has been demonstrated in type 1 diabetes (T1D); lower concentrations of pancreatic enzymes have been associated with metabolic risk (MR). Influence of puberty and MR factors on serum concentrations of amylase and lipase remain unexplored in Indian youth with T1D. 1) To characterize and predict determinants of serum amylase and lipase concentrations in adolescents/youth with T1D.

Hypothyroidism is known to affect memory consolidation, and our prior research highlighted the potential of chrysin as a therapeutic agent to restore cognitive function. The present study aimed to investigate the action mechanism of chrysin on memory deficits in hypothyroid in C57BL/6 female mice. We assessed cognitive flexibility, declarative, working, and aversive memories while analyzing the BDNF/TrkB/AKT/Creb neuroplasticity signaling pathway and synaptic function in the hippocampus and prefrontal cortex.

Article Synopsis
  • Graves' disease (GD) is an autoimmune disorder where the body's antibodies stimulate the TSH receptor, causing excessive thyroid hormone production.
  • Diagnosis typically involves assessing symptoms and a thyroid panel, with specific tests for TSH Receptor Antibodies (TRAbs) aiding in diagnosis and management strategies.
  • Recent guidelines from experienced endocrinologists emphasize the importance of TRAbs in GD management to improve effectiveness and decision-making for healthcare providers, particularly in South Asia.

Hypothyroidism is the most prevalent thyroid disorder and leads to adverse effects on the human body. Serum thyroid stimulating hormone (TSH) values have been related to polymorphisms in multiple genes that may be involved in the regulation of thyroid function. The single nucleotide polymorphism (SNP) rs2046045 is situated in the intron region of the phosphodiesterase 8B (PDE8B) gene, which encodes a high-affinity cyclic adenosine monophosphate (cAMP)-specific phosphodiesterase widely expressed in thyroid tissue.

Purpose: Iodine nutrition during pregnancy plays an important role in fetal development and maternal outcomes. Iodine deficiency has been proved to be associated with maternal thyroid dysfunction, adverse fetal outcomes and neurodevelopmental disorders in offspring. At present, there are few studies concentrate on the effects of iodine excess during pregnancy on thyroid function, maternal and neonatal outcomes, and the results are still controversial.
