Inflammation in Melasma: Study of Its Infiltrate and the Expression of Acute and Chronic Mediators
In Brief
An observational study for Melasma. Completed, enrolled 20 participants across 1 site.
Detailed Summary
Melasma is an acquired hyperpigmentary disorder that commonly affects women from Asia and Latin-America.There is evidence of subclinical inflammation supported by diffuse spectrometry and by prominent inflammatory cells in affected areas; however this infiltrate and its inflammatory mediators remains unexplored. Chronic inflammation induces melanogenesis and angiogenesis; thus, it could be linked to its recurrent nature.Therefore, the aim of this study is to describe the inflammatory cellular infiltrate, and the expression of main inflammatory and angiogenic mediators in this condition, as well as to explore its relationship with severity of disease. Using histological, histochemistry, immunohistochemistry, and quantitative real-time PCR, we evaluated melasma lesions from 20 healthy female patients with malar melasma without specific solar exposure or photoprotection measures within the previous 3 weeks and compared them to non lesional skin.
