The committee will review select conditions related to the immune system and address diagnosis, treatment, and prognosis of those conditions. The select conditions should include but may not be limited to Systemic Lupus Erythematosus, Scleroderma, Polymyositis, Sjogren's syndrome, and Inflammatory Arthritis, but should exclude HIV. The committee will identify aspects of the select conditions such as average age of onset, professionally accepted diagnostic techniques and criteria, methods for differentiating severity, usual course of the disorder, secondary impairment, treatments, treatment settings, likelihood of improvement, and any limitation on the availability of treatment.
