Sarcoidosis overview on November 13, 2002

This disease is a systemic disorder that can affect any organ in the body, with pulmonary involvement being the most common. After China reported its first case in 1958, numerous reports have since emerged across the country. In 1982, the Chinese Sarcoidosis Treatment Collaboration Group was established; over the subsequent 20 years until 2002, 198 hospitals published 502 articles reporting a total of 5,000 cases. The etiology of this disease remains unclear; some believe it may be associated with tuberculosis or spirochete infections. Affected organs include the lungs, liver, eyes, spleen, skin, and lymph nodes. Nearly 80% of cases initially involve the lungs, with main symptoms including high fever, accelerated erythrocyte sedimentation rate, elevated γ-globulin levels, nodular lesions in the lungs, positive antinuclear antibody tests, though negative results are also possible. Clinical treatment primarily relies on corticosteroids.
