Mortality in Crohn's Disease

P Prior et al. Gastroenterology.


A series of 513 patients with Crohn's disease, who were followed for 1 to more than 35 yr by one unit, experienced a twofold increased risk of dying compared with a matched group drawn from the general population (102 observed; 51.8 expected; p < 0.001). The overall risk was similar for men and women and was greatest in the younger patients within a few years of diagnosis. The relative risk of dying decreased as the age at diagnosis of their Crohn's disease increased and also fell as the period of time from diagnosis increased. There was a small but significant excess of death from tumors of the digestive organs (9 observed; 4 expected; p < 0.05). There was also a significant excess of deaths from suicide in women (3 observed; 0.4 expected; p < 0.01). The major burden of mortality lay in causes directly attributable to Crohn's disease or to associated complications within the digestive system (46 observed; 1.41 expected; p < 0.001).
