まとめ
糖尿病の成人は,骨の健康にさまざまなリスクがあります. 1型糖尿病は骨密度が低いことと関連しており,2型糖尿病は骨密度が高いにもかかわらず骨折のリスクが高く,個別化された骨の評価が必要である.
科学分野:
- 内分泌学と骨代謝について
- 糖尿病研究研究 糖尿病研究
- 骨粗鬆症と脆弱性骨折による骨折
背景:
- 糖尿病 (DM) は,骨の脆さの既知の危険因子です.
- 1型DM (T1DM) は通常,低骨密度 (BMD) と関連しているが,2型DM (T2DM) は,しばしばBMDが高く,骨折のリスクが増加している.
- 異なるタイプの糖尿病における骨の健康に関する大規模な比較研究は限られている.
研究 の 目的:
- T1DMとT2DMの成人の骨の健康を評価するために,骨折症,骨粗鬆症,骨折リスクを含む骨の健康を評価します.
- 糖尿病患者集団における低骨密度の予測要因を特定する.
主な方法:
- トルコの27のセンターで2562人の患者 (224人がT1DM,2338人がT2DM) を対象とした多センター,横断的な研究です.
- 骨のミネラル密度 (BMD) は,二重エネルギーX線吸収計 (DXA) を使用して評価されました.
- 骨折リスクは,40歳以上でトルコに適応したFRAX®アルゴリズムを使用して推定され,マルチノミアルロジスティック回帰により,低BMDの独立した予測要因が特定されました.
主要な成果:
- 骨粗鬆症の罹患率はT1DMでは5.5%,T2DMでは9.6%でした (股関節頸部Tスコア).
- T1DM患者は,T2DM患者と比較して,すべての骨格部位で調整されたBMDが著しく低下しました.
- T2DM患者には,FRAXベースの骨折のリスクが高く,転倒による骨折の発生率が高かった. オステオポロシスの独立予測要因には,高齢,女性,低BMI,低カルシウムレベル,コルチコステロイド使用,アルブミヌーリア,高血圧,SGLT2阻害剤の頻度の低い使用が含まれています. T1DMは骨粗鬆症と関連していたが,骨粗鬆症とは関連していなかった.
結論:
- T1DMとT2DMの間には,骨髄損傷と骨折リスクの明確なパターンが存在します.
- 個別化された骨の健康評価は,日常的な糖尿病のケアにおいて極めて重要です.
- SGLT2阻害剤の使用を含む変更可能な要因は,糖尿病患者の骨粗鬆症のリスクと関連しています.

01:29Bone Disorders
5.6K
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...

01:27Fractures: Bone Repair
5.7K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

01:25Role of Vitamins in Maintaining Bone Health
5.7K
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...

01:31Essential Minerals for Bone Health
6.6K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

01:20Pathophysiology of Diabetes
3.8K
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

01:15Diabetes: Symptoms, Diagnosis, and Complications
2.4K
For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...
