Abstract

BACKGROUND AND OBJECTIVES:

Acne vulgaris is a distressing skin condition, which can carry with it significant psychological disability. Oxidant/antioxidant imbalance leads to increased production of free radicals, that cause many diseases. Some nutrients, along with systemic oxidative stress, have been implicated in acne vulgaris. The goal of the present study was to assess oxidant and antioxidant status in correlation with the incidence of acne vulgaris in adolescent obese females.

MATERIALS AND METHODS:

A total of 60 adolescent females (age 16-22 years) were divided into four groups (15 each) as follows: The first included obese females with acne; the second included obese females without acne; the third included non obese with acne and the fourth included non obese without acne. Fasting serum Malondialdehyde (MDA), beta-carotene, and Vitamins A, E, and C were measured. In addition, platelet monoamineoxidase (MAO), and erythrocyte catechol-o-methyltransferase (COMT) activities were determined.

RESULTS:

It was found that serum MDA was statistically significantly decreased in obese and non obese subjects with acne, as compared to those without acne (P<0.05, P<0.001) respectively. In contrast, the levels of beta-carotene, vitamins A, E and C and the activity of MAO were significantly decreased in the obese and non obese with acne, as against the obese and non obese without acne.

INTERPRETATION:

In obese subjects, increased fat content facilitates free radical production and lipid peroxidation, as indicated by increased MDA level, which is scavenged by the antioxidant vitamins. The decreased activity of MAO may be inhibited by free radicals and this causes psychological depression in adolescents. However there were non significant changes in the activity of COMT among the studied groups.

CONCLUSION:

The nutritional factors and a weakened antioxidant defense system may interplay, to increase the risk of psychological sequelae in acne vulgaris.
