Estudo das dermatoses e sua prevalencia em individuos comprovadamente alcoolistas comparativamente a um grupo de individuos não alcoolistas

Abstract

Background: The direct relationship between alcoholism and dermatoses has been evaluated in recent researches. However, there are few objective surveys that demonstrate and prove a direct relationship between alcohol and a specific dermatosis. Objectives: to verify the prevalence of dermatoses in alcoholics, analize the der-matological changes found in these patients and their evolution during alcoholic abstinence. Also, to compare the results obtained with a non-alcoholic control group and with the data found in medical literature. Methods: the dermatologic conditions of 278 alcoholic patients (250 men, 28 women) were studied over a period of 4 years, and compared to those of a control group of 271 non-alcoholic individuals (249 men, 22 women), members of the Military Police Force. The individuals in both groups were between 20 and 60 years old. Results: Pellagra, num-mular eczema, purpura pigmentosa chronica (also known as pigmented purpuric dermatosis) and psoriasis were more frequent in the group of alcoholics and, apparently, occurred in parallel with alcoholism that seems to play a role in the evolution of these dermatoses. The dermatopathies were more frequent before the age of forty, regardless of factors such as profession, race or gender. Conclusion: the association of dermatoses and alcoholism was extremely significant according to the statistical data. Alcoholism can be considered a risk factor for pellagra, psoriasis, nummular eczema and purpura pigmentosa chronica dermatoses, which can, as well, be considered alcoholism indicators. © 2013 by Anais Brasileiros de Dermatologia.
