まとめ
プルリゴ・ノドゥラリス (PN) の患者は,狼,シェーグレン症候群,牛皮病などの自己免疫疾患を発症するリスクが高くなります. これはPN患者の早期自己免疫疾患のスクリーニングの必要性を強調しています.
科学分野:
- 皮膚科
- リウマトロジ
- 流行病学
背景:
- プルリゴ・ノドゥーラリス (PN) は慢性炎症性皮膚疾患である.
- 過去の研究では PNと自己免疫疾患との関連が示唆されている.
- PN患者の自己免疫疾患の発症に関する縦断的なデータは限られている.
研究 の 目的:
- Prurigo nodularisの患者で発生した自己免疫疾患の長期的リスクを調査する.
- PN患者の自己免疫疾患の発生率を対照群と比較する.
主な方法:
- トリネットX研究ネットワークのデータベースを使用した遡及コホート研究.
- PN患者と対照群の傾向スコアマッチング (年齢,性別,併発症,人種,社会経済的地位)
- 以前から自己免疫疾患やがんを患っていた患者を除外し,危険比率を用いて自己免疫疾患を評価する.
主要な成果:
- PN患者は,全身性狼症 (SLE) (HR: 2. 16),シーグレンの症候群 (HR: 1. 86),および牛皮病 (HR: 3. 20) のリスクが著しく高かった.
- SLEとSjögren症候群のリスクは女性PN患者でより顕著でした.
- 特に男性では,AS,RA,CD,UCの有意なリスク増加はありません.
結論:
- Prurigo nodularisは,SLE,シェーグレン症候群,および疹を発症するリスクの増加と関連しています.
- PN患者における自己免疫疾患に対する積極的なスクリーニングと管理の重要性を強調しています.
- パーキンソン病と特定の自己免疫疾患を結びつける根本的なメカニズムをさらに研究することができる.

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.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Nephrotic Syndrome II : Assessment and Medical Management
21
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

Changes in Skin Color: Clinical Perspectives
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
Albinism is a genetic disorder that affects (completely or partially) the coloring of skin, hair, and eyes. The defect is primarily...

Nephrotic Syndrome I : Introduction
25
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...
