Prevalence of Psoriasis and Vitiligo in Assiut Governorate, Egypt
Study Purpose
Psoriasis is a chronic, immune-mediated inflammatory skin disease, which ranges in severity from a few scattered red, scaly plaques to involvement of almost the entire body surface. It may progressively worsen with age, or wax and wane in its severity; the degree of severity depends on inheritance and environmental factors. It is a complex disease, multiple exogenous and endogenous stimuli incite already stimulated innate immune responses in genetically predetermined individuals. The disease process is a result of a network of cell types including T cells, dendritic cells and keratinocytes that, with the production of cytokines, generate a chronic inflammatory state. Vitiligo is a chronic disorder of pigmentation characterized by the development of white macules on the skin due to loss of epidermal melanocytes. Its pathogenesis is still unclear, many mechanisms and theories have been suggested including autoimmunity, auto cytotoxicity, biochemical and neuronal mechanisms.

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
