Brief Summary: Alopecia areata AA is a type of non-cicatricial alopecia The most common presentation of AA is localized patches of hair loss on the scalp The extensive forms of AA presented as diffuse hair loss of the scalp alopecia totalis and diffuse hair loss through the entire body including the eyelashes and eyebrows alopecia universalis

AA affects approximately 2 of the general population AA occurs at any age The peak of incidence is higher in the second and third decades of life

AA may be associated with several autoimmune diseases including thyroid diseases lupus erythematosus vitiligo psoriasis rheumatoid arthritis and inflammatory bowel disease The frequency of the disease varies between geographically separate populations These diseases associations suggest a relationship between AA and autoimmunity

Human hair has an important cosmetic and communicational role We may find significant psychological distress in persons with partial and complete hair loss AA is associated with psychiatric morbidity especially anxiety and depression

The pathogenesis of AA involves a complex interaction between genetic environmental and immune factors The histopathology of the disease differs according to the stage of the disease In the acute stage of AA there is a dense accumulation of lymphocytes CD4 CD8 around hair bulbs so called swarm of bees In chronic stage the inflammation may or may not resolve but there is increase in number of catagen and or telogen hair and pigmentary incontinence In the recovery stage there is minimal inflammation and increase in anagen hair

T-helper17 cells are unique subset of T-helper cells which produce many interleukins IL eg IL-17A IL-17F IL-21 IL-22 IL-6 and tumor necrosis factor TNF The maturation of Th-17 needs the stimulation of naïve T cells by both TGF and IL-21 IL-21 is a cytokine that is produced mostly by activated CD4 T cells It controls the differentiation and activity of T cells B cells and NK cells IL-21 could be a promising marker in the diagnosis of AA and also can be used as a marker of its activity

IL-15 is a pleotropic cytokine that has multiple effects on different body cell types It affects the function of cells of both innate and adaptive immune system IL-15 is well known to promote lymphocytic development and suggested to play a role in some autoimmune diseases eg multiple sclerosis rheumatoid arthritis ulcerative colitis and celiac disease IL-15 inhibits the well-known self-tolerance that mediated by activation - induced cell death promotes maintenance of CD8 memory T cells with induction of some cytokines which involved in autoimmune process eg TNF- and IL-1B IL-15 is positively correlated with the number and the extent of AA so it could be a possible marker of AA severity
