背景:
- アトピー性皮膚炎 (AD) は,子供と成人の両方に影響する慢性炎症性皮膚疾患です.
- ビタミンDのような潜在的治療薬の調査はADの重症性を管理する上で極めて重要です.
研究 の 目的:
- アトピー性皮膚炎の管理におけるビタミンDの臨床的意義と治療効果を批判的に評価する.
- 様々な研究デザインから,ADにおけるビタミンDの役割に関する現在の証拠を合成する.
主な方法:
- 観察研究,動物研究,ランダム化制御試験 (RCT) の包括的な文献レビュー.
- 2019年以降に出版された研究については,英語の全文原稿を用いて,PubMedデータベースで検索を行った.
主要な成果:
- 観察研究では,潜在的治療効果と,ADに対するビタミンDの有意な影響の両方を示した結果が出ました.
- ビタミンD受容体 (VDR) の多形化はADの発生と重症度と相関することがあります.
- RCTと動物実験では,マウスでの症状の緩和が動物モデルで示され,不確実または限られた証拠が得られました.
結論:
- アトピー性皮膚炎におけるビタミンDの有効性に関する現在の研究は,矛盾する結果と方法論的な限界のために不確実です.

01:23Role of Skin in Vitamin D Synthesis
5.6K
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...

Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

2.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

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...
