まとめ
自己免疫性甲状腺機能低下症の人は,重度の歯周病のリスクが高くなります. この研究では,抗甲状腺過酸化酵素 (anti- TPO) 抗体などの甲状腺機能障害マーカーと歯周組織損失の増加との間に有意な関連性が見られた.
科学分野:
- 内分泌学
- 歯周病学
- 免疫学
背景:
- 炎症性サイトカインは,自己免疫性甲状腺機能低下症と歯周病の病原性に関与しています.
- 累積した炎症マーカーは,重大な歯周病の崩壊に寄与する可能性があります.
研究 の 目的:
- 自己免疫性甲状腺機能低下患者の歯周病の流行と重症度を評価する.
- 臨床結合喪失 (CAL) と歯周炎表面積 (PISA) を甲状腺マーカー (抗TPO抗体,T3,T4,TSH) とC反応性タンパク質 (CRP) と関連付ける.
主な方法:
- 治療を受けた65人の自己免疫性甲状腺機能低下患者と,全身的に健康な75人の被験者を比較した横断的な研究.
- 歯周病のパラメータ (BoP,PPD,CAL,OHI-S,PI,PISA) と全身のパラメータ (T3,T4,TSH,TPO抗体,CRP) の評価
- ペアリングされていないtテストとChi-Squareテストを用いたデータ分析.
主要な成果:
- 歯周炎の有意に高い罹患率と重症度は,自己免疫性甲状腺機能低下群 (p < 0. 001) であった.
- CAL,PISA,T3,TSH,および抗TPO抗体のレベルが,自己免疫性甲状腺機能低下患者で上昇した.
- TPO抗体,T3,T4,TSH,CRPとの平均CALとPISAとの間の正の相関関係 平均CALと有意に関連した抗TPO抗体 (β = 0. 001, p = 0. 02).
結論:
- 自己免疫性甲状腺機能低下患者は歯周炎の流行と重症度が増加しています.
- 自身免疫性甲状腺機能低下群では,BoP,PPD,CAL,PISAのレベルが上昇した.
- CAL,PISA,甲状腺関連のマーカー (抗TPO抗体,T3,TSH,CRP) の間に有意な正の相関が認められた.

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...

The Thyroid Gland
4.3K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

Autoimmune Disorders
671
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Functions of Thyroid Hormones
3.2K
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...
