まとめ
アイソトレチノイン (IOS) によるの治療は,甲状腺機能に影響を及ぼす可能性があります. 研究によると,IOSは甲状腺を刺激するホルモンを増加させ,トリヨドチロニンと甲状腺素のレベルを低下させ,潜在的に甲状腺のサブ臨床的変化を示唆しています.
科学分野:
- 皮膚科と内分泌科
- 薬理学と治療法
背景:
- アクネ・ヴルガリス (AV) は,イソトレチノイン (IOS) で効果的に治療される一般的な皮膚疾患です.
- IOSは全身のレチノイドで,抗炎症およびセボスプレッシブ効果がありますが,甲状腺機能への影響は完全に理解されていません.
- IOSは,ステロイド-甲状腺ホルモンのスーパーファミリーを含む核受容体と相互作用する.
研究 の 目的:
- アクネ・ヴルガリス (AV) の患者における甲状腺ホルモンレベルに対するイソトレチノイン (IOS) 治療の影響を評価する.
主な方法:
- 4ヶ月間,0. 5 - 1 mg/ kg/ dayのIOSで治療された50人のAV患者を対象とした前向きな研究.
- トライオードチロニン (T3),甲状腺刺激ホルモン (TSH),チロキシン (T4) の血清濃度は,IOS治療前と後に測定された.
主要な成果:
- 治療後,TSH濃度の有意な上昇が観察された (P < .000).
- トライヨドチロニン (T3) とチロキシン (T4) の濃度が基値と比較して有意に低下した (P< .000).
結論:
- アイソトレチノイン (IOS) 治療は,甲状腺ホルモンの合成と調節に影響を与え,潜在的に甲状腺機能の変化を引き起こす可能性があります.
- IOS治療中に甲状腺のパラメータをモニタリングすることが推奨されます.
- メカニズムと臨床的影響を明らかにするために,より大きなコホートでのさらなる研究が必要です.

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...

Functions of Thyroid Hormones

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...

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...

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids
201
Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Hyperlipidemia, a medical condition often referred to as high cholesterol, is characterized by abnormally elevated levels of lipids in the bloodstream. When present in excess, these lipids, specifically cholesterol and triglycerides, can lead to serious health complications, often involving cardiovascular diseases. Illnesses like atherosclerosis, heart attacks, and pancreatitis have all been linked to untreated hyperlipidemia. This means controlling and regulating cholesterol and triglyceride...

Drugs for Treatment of Crohn's Disease in IBD Using Immunomodulatory Agents
264
Crohn's disease is an inflammatory bowel disorder marked by chronic inflammation of the GI tract. Various treatment strategies for Crohn's disease are employed, such as immunomodulatory agents, glucocorticoids, and biologics or anti-TNF therapy. Azathioprine (Imuran), a commonly used immunomodulatory drug for Crohn's disease, is converted in the body to mercaptopurine, which inhibits purine biosynthesis and cell proliferation. Both are utilized in severe cases of Inflammatory Bowel...
