Abstract
Alopecia areata (AA) is second most common disease leading to non scarring alopecia . It occurs in many patterns and can occur on any hair bearing site of the body. Many factors like family history, autoimmune conditions and environment play a major role in its etio-pathogenesis. Histopathology shows bulbar lymphocytes surrounding either terminal hair or vellus hair resembling "swarm of bees" appearance depending on chronicity of alopecia areata. Alopecia areata in children is frequently seen. Pediatric AA has been associated with atopy, thyroid abnormalities and a positive family history. We have done a study to find out if there is any association between alopecia areata and other auto immune diseases in children. This study is an observational study conducted in 100 children with AA to determine any associated autoimmune conditions in them. SALT score helps to assess severity of alopecia areata. Severity of alopecia areata was assessed by SALT score-1. S1- less than 25% of hairloss, 2. S2- 25-45% of hairloss, 3. 3.S3- 50-74% of hairloss.
