Abstract
Forty-seven per cent of patients with Crohn's disease showed migration inhibition of their leucocytes in the presence of Kveim antigen. The incidence of positive tests bore no relationship to the severity of the disease or to corticosteroid therapy. Similar tests were consistently negative in twenty-four patients with idiopathic proctocolitis. The significance and diagnostic implications of these findings are discussed.
