A COMPREHENSIVE REVIEW ON THE PATHOPHYSIOLOGY, DIAGNOSIS AND TREATMENT OF SARCOIDOSIS

摘要

Sarcoidosis is a rare autoimmune inflammatory disease, which is difficult to diagnose due to a lack of approved clinical tests. It has been observed in each race, and highest among the Scandinavia, African-American but Asians are less vulnerable to it. It affects most prominently adults from the age group of 20 to 60. The main characterized symptom of this disease is non-caseating granulomas, specifically in the lungs and lymph nodes progressing to lungs impairment to pass oxygen, and finally total failure of lungs as well as heart. The main cause of sarcoidosis is immune irregularities in genetically predisposed individuals which manifests antigen(s) like microorganism or their products, due to an ex-aggregated immune response. There is no specific treatment available, although corticosteroids help in disappearing its symptoms. While more than 50 percent of the patients don’t require any treatment and illness goes on its own, only 10% require treatment in which severe symptoms developed and last long. The current review enlightens the pathogenesis of the disease, clinical indications, diagnostic evaluation, and various therapies for the treatment.
