Psoriasis is a life-long chronic autoimmune disease characterized by thick scaly skin lesions and often associated with severe arthritis. In psoriasis, lesions skin cells, keratinocytes, grow too quickly, resulting in thick, white, silvery or red patches on skin. Normal skin cells grow gradually and flake off about every four weeks, but psoriasis causes new skin cells to move rapidly to the surface of the skin in days rather than weeks. Psoriasis symptoms often appear on the elbows, scalp, feet, knees, hands, or lower back, or as flaking or patches on the skin. It is most common in adults, but teenagers and children can also suffer from psoriasis.

Psoriasis is not only a skin condition; it is a chronic disease of the immune system. Chronic psoriasis is associated with other health conditions such as psoriatic arthritis, several inflammatory disorders, type 2 diabetes, and cardiovascular disease. This book provides extensive coverage of psoriasis and psoriatic arthritis. It features information on epidemiology and etiology of psoriasis, pathogenesis, genetics of psoriasis, clinical manifestations, and treatment options using cutting-edge drugs including adalimumab and tofacitinib.

Natural phytochemicals and nutraceuticals have demonstrated efficacy in ameliorating psoriasis. The book dedicates comprehensive coverage of nutraceutical therapeutic options including antioxidants, bioactive peptides, carotenoids, alpha lipoic acid, curcumin, and whey protein.
