まとめ
小児の自己免疫疾患患者はしばしばビタミンDのレベルが低く,70%以上が不十分または欠乏を示しています. しかし,この研究グループでは,ビタミンD濃度が疾患の活動と相関していなかった.
科学分野:
- 小児関節病学
- 免疫学
- 内分泌学
背景:
- ビタミンDは 免疫系を調節する重要な要素です
- 低ビタミンDレベルは 自身免疫疾患と頻繁に関連しています
- 以前の研究では ビタミンD欠乏症が 狼症,関節リウマチ,甲状腺炎などの疾患に 関連していることが分かりました
研究 の 目的:
- 自身免疫疾患を持つ子供のビタミンD状態を評価する.
- 小児患者のビタミンDレベルと疾患の特徴の間の潜在的な相関を調べる.
主な方法:
- 記述的・横断的な研究デザイン
- 自己免疫疾患と診断された小児患者 (< 18歳) を含む.
- 2016年1月から2020年12月までの3つの専門診療所のデータ収集.
主要な成果:
- 81人の小児患者 (74%が女性,平均年齢9歳) を分析した.
- ジュベニアル・イディオパシー・関節炎は最も一般的な診断 (65. 4%) でした.
- ビタミンD欠乏症 (50. 6%) と欠乏症 (24. 7%) の高い流行が観察され,十分なレベルは23. 5%のみであった.
- ビタミンD濃度と性別,年齢,病気の寛解,ANA値,または季節の間の有意な相関は見つかりませんでした.
結論:
- 自免疫疾患の小児患者は,しばしばビタミンD不足または欠乏症を呈する.
- 現在のビタミンD濃度は,このコホートにおける疾患活動マーカーと統計的に有意な関連性を示さなかった.
- ビタミンDと小児の自己免疫疾患の複雑な相互作用を理解するには,さらなる研究が必要かもしれません.

Autoimmune Disorders
666
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Role 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...

Immunodeficiency Diseases
1.2K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Connective Tissue Cell Types
3.4K
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...

Development of Immunocompetence
444
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
