[Influence of exogenous and endogenous factors on the course of psoriasis]

Abstract

Psoriasis is a chronic, inflammatory disease, which symptoms appear mainly within the skin. Genetic and environmental factors are known to play a key role in etiopathogenesis of psoriasis. Therapy directed against psoriasis includes the topical and the systemic treatment. The immunotherapy (biologicals) is known to be relatively less harmful, due to action strictly against proinflammatory molecules, responsible in part for the progression of psoriasis. Because of substantial role of environmental factors in the etiopathogenesis of psoriasis, it is possible to get a clinical improvement of psoriatic lesions by modification of patients dietary habits and their lifestyle. Reduction of the calorific value of meals, the bodyweight reduction, the diet rich in unsaturated fats and antioxidants, likewise, abstinence and the reduction of stress level in everyday life, are known to have a positive effect on the course of psoriasis. It is stated that psoriatic patients are suffering from many other diseases e.g. cardiovascular, respiratory and hormonal diseases, whose treatment might exacerbate psoriasis. Thus, patients with psoriasis following the appropriate recommendations can greatly reduce disease progression.
