title: HLA-B18 antigens and protection from pulmonary fibrosis in asbestos workers.
abstract: HLA antigens were identified in 64 patients with radiographic asbestosis and 37 matched controls with equivalent asbestos exposure but no radiographic pulmonary fibrosis. A high prevalence of HLA-B18, B27 and Cw2 was found in the controls. This result might indicate that the possessors of these HLA antigens are thus protected from the development of diffuse pulmonary fibrosis from asbestos exposure. Signs of susceptibility were not demonstrated. The radiographic severity and progression of asbestosis were not associated with any of the HLA antigens tested.
