まとめ
抗レトロウイルス治療 (ART) を開始したHIV感染者 (PWH) の体重増加は,骨由来ホルモン,特に低炭酸化オステオカルシン (ucOCN) とリポカリン2 (NGAL) の変化に関連しています. この関連性は,使用された特定のART療法によって異なる.

背景:
- 体重増加は,抗レトロウイルス治療 (ART) を開始したHIV感染者 (PWH) の頻繁な副作用です.
- ARTに関連した体重増加の正確な生物学的なメカニズムは,まだ完全に理解されていません.
- 骨由来ホルモンは代謝調節に関与しており,ART誘発の体重変化に潜在的役割を果たしていることを示唆している.
研究 の 目的:
- 特定の骨由来ホルモンと,ARTを開始した治療前のPWHの体重増加との関連を調査する.
- これらの関連が異なる抗レトロウイルス薬 (ARV) クラスに特異的であるかどうかを判断する.
主な方法:
- ATV/r,DRV/r,またはRALでTDF/FTCを開始した治療前のPWHを含むACTG研究A5260sの血サンプルを分析.
- 低炭酸化オステオカルシン (ucOCN),リポカリン- 2 (NGAL),およびスクレロスティンの血値の測定
- 線形回帰モデルを使用して,ホルモン濃度と体重の変化の関係を評価し,共変数で調整した.
主要な成果:
- ucOCNの上昇とNGALの低下は,ARTを受けたPWHの体重変化と有意に関連していました.
- スクレロスティンの濃度は体重変化と有意な関連性を示さなかった.
- ucOCNとNGALと体重変化の関連性は,主にラルテグラビール (RAL) ベースのARTを投与した患者で,プロテアース阻害剤 (ATV/ r,DRV/ r) による治療療法では観察されなかった.

01:17Hormones and Bone Tissue
2.9K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:29Bone Disorders
3.9K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:40Bone Remodeling
38.5K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

01:10Retrovirus Life Cycles
46.7K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

01:16Insulin: Dosing Regimen and Adverse Effects
252
Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

01:25Role of Vitamins in Maintaining Bone Health
3.6K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
