title: HLA-Bw15 and tuberculosis in a North American black population.
abstract: Peripheral blood lymphocytes from 60 black patients with Mycobacterium tuberculosis disease proved by culture and 100 healthy black persons were HLA phenotyped using a standard lymphocytotoxicity test. Statistical analysis of the results showed that only Bw15 antigen had a significantly increased frequency among patients with tuberculosis when they were compared to healthy persons. Furthermore, examination of disease manifestations among patients with tuberculosis demonstrated that patients with Bw15 had significantly more far-advanced pulmonary disease with cavitation than did patients without Bw15. These observations suggest that Bw15 may influence both susceptibility to tuberculosis and the course of the disease.
