まとめ
ビタミンD欠乏症は2型糖尿病患者の甲状腺疾患と関連しています. 甲状腺に問題がある糖尿病患者には,ビタミンDの不足のスクリーニングが推奨されます.
科学分野:
- 内分泌学
- 代謝障害
- 栄養学
背景:
- 2型糖尿病 (T2DM) の成人のビタミンD状態と甲状腺機能の関連性を調べる.
- 2018年から2024年にかけて,第2型糖尿病で治療を受けた1,805人の患者を調査しています.
- 甲状腺機能障害に対するビタミンDの影響を理解するために,人口統計,代謝,甲状腺のパラメータを分析します.
研究 の 目的:
- T2DM患者におけるビタミンD濃度と甲状腺機能の関連性を調べる.
- この集団における 甲状腺機能不全における ビタミンDの役割を調べるため
- 潜在的なスクリーニングガイドラインの証拠を提供するために.
主な方法:
- 血25-ヒドロキシビタミンD,甲状腺ホルモン (FT3,FT4,TSH),および自己抗体 (TPOAb,TGAb,TRAb) の測定は電気化学発光を用いて行われました.
- HPLCによるHbA1cの評価
- ビタミンD状態 (欠乏,不十分,十分) と甲状腺疾患との関係を分析するためにスピアーマン相関とロジスティック回帰を用いた.
主要な成果:
- ビタミンDの不足は男性性,年長,高FT3と関連しているが,逆には高トリグリセリドとHbA1cと関連している.
- 甲状腺機能不全はビタミンDの不足と 年齢の低さに関連しています
- 甲状腺機能低下は老化と高コレステロールに関連しており,ビタミンDと甲状腺の自己免疫性との関連は見つかりませんでした.
結論:
- ビタミンD欠乏症は,T2DM患者における甲状腺機能過剰症とサブクリニック性甲状腺機能過剰症と独立して関連しています.
- 2型糖尿病患者の甲状腺機能不全における ビタミンDの潜在的な役割を示唆している.
- 甲状腺機能障害を呈する糖尿病患者のビタミンD欠乏症のスクリーニングをサポートします.

Synthesis and Regulation of Thyroid Hormones
5.1K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Diabetes Mellitus: Type 2 and Gestational
2.9K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Functions of Thyroid Hormones
3.1K
The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Diabetes Mellitus: Overview and Type I Subtype
3.2K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Role of Skin in Vitamin D Synthesis
5.6K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Connective Tissue Cell Types
3.4K
Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...
