[Immunological studies and the problems of the pathogenesis of osteoarticular tuberculosis (tuberculous spondylitis,...

Tests of levels 1-2 were employed to study immune status of 102 patients with tuberculous lesions of the spine and knee joint. Investigations of humoral local response in these patients provided evidence for comparison with systemic response, advanced diagnosis of tuberculous spondylitis and synovitis. It was found that high level of antituberculous antibodies in the synovial fluid is typical for specific allergic synovitis where synovial membrane represents the organ of immunogenesis. The appearance of even minimal number of antituberculous antibodies in the liquor indicates disorder of immune and hematoencephalic barriers of the brain in tuberculous spondylitis complicated with spinal meningitis.
