概括

结节 (PN) 患者患有各种肝脏疾病的风险明显更高,包括肝硬化和癌症. 基因分析揭示了共同的风险因素,表明皮肤-肝脏轴可能会为新的PN治疗提供信息.

科学领域:

皮肤病学皮肤病学
肝病学肝病学是一种肝病学.
遗传学遗传学是一个

背景情况:

与肝脏功能障碍有关,但肝脏疾病与结节 (PN) 之间的联系还不清楚.
结 (prurigo nodularis) 是一种慢性炎症性皮肤疾病,其特征是严重的.

研究的目的:

为了研究肝病与结节炎之间的关联.
探索这种关联的潜在遗传基础.

主要方法:

使用TriNetX全球健康研究网络对PN患者肝脏并发症的横截面分析.
对PN皮肤病变进行皮肤转录组分析和基因组变异分析 (GSVA).
使用FinnGen队列进行全基因组关联研究 (GWAS).

主要成果:

与对照组相比,PN患者的肝硬化,肝衰竭,慢性肝炎,非酒精性脂肪肝炎,门性高血压,脂肪肝和肝细胞癌的风险显著增加.
在PN患者中,肝病的累积发病率大约是PN患者的三倍.
转录组分析揭示了PN皮肤中与肝病相关的失调基因和激活途径.
在包括AR,EDIL3,MACROD2,PCSK5,RUNX1T1,TENM4和ZEB2在内的基因中,GWAS确定了PN和肝病之间的共享单核酸多态 (SNP).

结论:

在PN患者中存在皮肤-肝脏轴的显著失调.
这一轴可能会导致PN肝病并发症的发病率和严重性增加.
研究结果表明,通过解决皮肤与肝脏的联系,可以为PN提供潜在的治疗点.

Changes in Skin Color: Clinical Perspectives

Changes in Skin Color: Clinical Perspectives

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...

Skin Diseases and Disorders

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...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...
