概括
维生素D缺乏在囊性纤维化中很常见. 高效调节剂疗法 (HEMT) 似乎没有纠正囊性纤维化 (CF) 患者的维生素D水平,这表明需要进一步研究.
科学领域:
- 生物化学 生物化学
- 医学研究 医学研究
- 肺部病理学 肺部病理学
背景情况:
- 维生素D缺乏症在患有囊性纤维化 (PwCF) 的人群中普遍存在,原因是吸收不良.
- 在PwCF中,维生素D对于骨健康和肺免疫是至关重要的.
- 高效调节器疗法 (HEMT) 增强了囊性纤维化转膜导电性调节器 (CFTR) 蛋白功能,改善了肺功能和脂肪吸收.
研究的目的:
- 研究高效调节剂疗法 (HEMT) 对囊性纤维化 (PwCF) 患者的维生素D状态的影响.
- 为了确定使用HEMT是否会影响PwCF的血清25-基维生素D (25(OH) D) 水平随着时间的推移.
主要方法:
- 在十年内对89名患有囊性纤维化 (CF) 的年轻成年人血清25-基维生素D (25(OH) D水平进行了回顾性分析.
- 患者根据当前高效调制剂疗法 (HEMT) 的使用 (是或不是) 进行了分类.
- 采用双向ANOVA,评估两组之间维生素D水平的趋势.
主要成果:
- 无论是HEMT使用者 (n=68) 还是非使用者 (n=21),在十年内,血清25(OH) D水平均显著下降 (平均下降分别为-14.2 ng/mL和-14 ng/mL).
- 在HEMT使用者和非使用者之间,维生素D水平的变化没有统计学上显著的差异 (p=0.44).
结论:
- 高效调节剂疗法 (HEMT) 可能无法解决囊性纤维化 (PwCF) 患者的维生素D缺乏症.
- 需要进一步进行大规模的前性研究,以充分理解CF中维生素D和HEMT之间的关系.
- 在PwCF中维持足够的维生素D水平可能需要持续监测和干预,独立于HEMT的使用.

Cystic Fibrosis: Management
146
Cystic fibrosis (CF) is an autosomal recessive disorder that predominantly affects individuals of Northern European descent, occurring at a rate of 1 in 3500. It is caused by a genetic mutation in a gene on chromosome 7, most commonly the ΔF508 mutation, that codes for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. This results in thicker mucus secretions and obstruction pathologies in multiple organs, including the lungs and sinuses.

Cystic Fibrosis: Pathogenesis
196
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

Role of Skin in Vitamin D Synthesis
5.1K
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin...

Role of Vitamins in Maintaining Bone Health
3.2K
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
328
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
