Abstract
Circulating IgG antibodies reactive with smooth muscle antigens have been found in 21% of patients with intrinsic asthma contrasting with an incidence of 2·9% in extrinsic asthma and 3·7% in chronic bronchitis. This antibody is neither organ nor species specific and does not cross-react with cardiac or skeletal muscle.
