Abstract

BACKGROUND:

In humans, oxidative stress is involved in many diseases such as atherosclerosis, Parkinson's disease, heart failure, myocardial infarction, Alzheimer's disease, Fragile X syndrome and chronic fatigue syndrome. Atopic dermatitis (AD), also known as atopic eczema, is a non-contagious, relapsing inflammatory skin disease which is characterized by eczema and pruritus. The skin reacts abnormally to irritants, food and environmental allergens and it becomes very itchy, which leads to scratching, redness and flaky skin. Very little study has been done to find out the relationship between oxidative stress and Atopic dermatitis.

AIM:

The aim of our work was to evaluate the status of oxidative stress in patients of Atopic dermatitis in comparison with healthy control subjects.

MATERIAL AND METHODS:

Twenty five patients of known Atopic dermatitis and 25 normal healthy controls of same age group were included in the study. Estimations of oxidants like Malondialdehyde (MDA), enzymatic antioxidants like Superoxide dismutase (SOD), Catalase, Glutathione peroxidase (GPX) and non-enzymatic antioxidants like reduced Glutathione (GSH), Vitamin A, Vitamin E and Vitamin C were done to assess the oxidative stress.

RESULTS:

Atopic dermatitis patients were more prone to damage caused by Reactive Oxygen Species (ROS) or Oxidants, than controls, which was evident from an increase of Malondialdehyde and a decrease of enzymatic and non enzymatic Antioxidants.

CONCLUSION:

Antioxidants may possibly be beneficial in the treatment of Atopic dermatitis, which must be substantiated by further studies.
