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...

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...

科学领域:

  • 皮肤病学
  • 免疫学
  • 蛋白质组学

背景情况:

  • 非细分性白风 (NSV) 的治疗具有挑战性,对潜在机制的了解有限.
  • 确定早期治疗反应标记对于优化NSV管理至关重要.

研究的目的:

  • 研究NSV患者的病变与非病变皮肤中的蛋白质差异.
  • 在NSV治疗初期分析皮肤和血液中的细胞和蛋白质标记物的变化.
  • 要将这些变化与临床复颜反应相关联.

主要方法:

  • 对接受局部治疗或NB-UVB光疗的30名NSV患者进行前性探索性研究.
  • 在治疗前3个月和治疗后3个月内从损伤和非损伤皮肤中分析泡液蛋白质.
  • 在皮肤活检和血液中评估细胞群 (T细胞,NK细胞).

主要成果:

  • 在病变和非病变皮肤预处理时,蛋白质有所不同.
  • 治疗导致皮肤中的CD3+,CD8+T细胞和T_RM细胞减少,泡液中的蛋白质发生了47次变化.
  • 皮肤T_RM细胞,血液中的Tr1细胞 (包括IL-10分泌) 和FABP4的减少与临床再染色相关.

结论:

  • 早期治疗引起的特定皮肤和血液标志物的变化,包括T_RM细胞和FABP4,与NSV的临床反应有关.
  • 治疗前的皮肤差异不能预测早期的治疗变化或临床结果.
  • 这些发现为白风治疗反应的免疫生物学提供了洞察力.
