概括
患有1型糖尿病 (T1D) 的青少年功能下降,骨多孔性略有增加. 然而,骨微型结构和生物标志物在很大程度上仍然相似,这表明骨在峰值骨质量附近的影响有限.
科学领域:
- 内分泌学 在内分泌学.
- 腎臟病學 (nephrology) 是一種醫學.
- 整形外科 整形外科 整形外科
背景情况:
- 1型糖尿病 (T1D) 与更高的骨折风险有关,特别是在微血管问题上.
- 估计的淋巴细胞过率 (eGFR) 的逐渐下降可能会影响T1D的骨健康.
- 了解EGFR下降对青少年T1D骨的影响对于骨折预防至关重要.
研究的目的:
- 研究eGFR逐渐下降如何影响T1D青少年和年轻成年人的骨生物标志物和微观架构.
- 为了确定T1D年轻人与没有显著的eGFR下降之间的骨健康的潜在差异.
主要方法:
- 在T1D年轻人中,计算了大约7.4年的eGFR斜率.
- 定义的"eGFR下降者"是那些eGFR下降≥3ml/min/1.73m2/year.的人.
- 在年轻成年期使用HRpQCT评估骨微架构和测量骨生物标志物 (骨,P1NP,CTX,骨特异性性酸酶).
- 使用线性回归分析了糖尿病持续时间,HbA1c,BMI,维生素D和骨参数之间的关联.
主要成果:
- 44%的参与者表现出EGFR下降,与非下降者相比,皮质毛孔直径增加了5% (p=0.035).
- 较长的糖尿病持续时间与较差的脊椎骨结构相关 (较高的分离,较低的数量).
- 较高的25-基维生素D水平与更好的脊椎骨结构 (较低的分离) 有关.
- 升高的HbA1c和BMI与较低的骨形成标志物有关.
结论:
- 患有T1D和eGFR衰退的青少年显示皮质多孔度略有增加,但整体骨微型结构和生物标志物与非衰退者相似.
- 骨损伤在T1D年轻人中似乎有限,高峰骨质附近的eGFR轨迹有所变化.
- 最佳的血糖控制,健康的BMI和足够的维生素D状态对于维持T1D骨健康至关重要.

Bone Disorders
3.5K
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...

Diabetes: Symptoms, Diagnosis, and Complications
524
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...

Diabetes Mellitus: Overview and Type I Subtype
2.6K
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...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Osteoclasts in Bone Remodeling
2.9K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Diabetes Mellitus: Type 2 and Gestational
2.3K
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...
