Mortality and causes of death in different celiac disease phenotypes during long-term follow-up.

Background: Celiac disease has been associated with increased mortality, but data on long-term mortality are scarce.
Aims: To determine long-term mortality in celiac disease.
Methods: The study cohort consisted of all celiac disease patients (n=1,392) diagnosed in Tampere University Hospital catchment area 1960 - 2000. Patients were categorized into subgroups based on demographic (age, gender, decade of diagnosis) and celiac disease characteristics (e.g., phenotype, severity of villous atrophy) collected from medical records. Overall and cause-specific mortality was compared to those of age-, sex-, and place of residence matched reference individuals (n=4,177) over time.
Results: During the 41 years of follow-up (median 26.5 years), 376 celiac disease patients and 1,155 reference individuals died. All-cause mortality was not increased (hazard ratio (HR) 0.96, 95% confidence intervals (CI) 0.85-1.08). Mortality from lymphoproliferative diseases and diseases of the central nervous system was increased (HR 2.42, 95% CI 1.38-4.24 and HR 2.14, 95% CI 1.05-4.36 respectively) while the risk from alcohol related diseases was decreased (HR 0.31, 95% CI 0.09-1.00). Examination of various celiac disease phenotypes revealed no significant differences in mortality CONCLUSIONS: Overall mortality was not increased in any celiac disease phenotype during a very long-term follow-up.
