Coeliac disease in the elderly in a tertiary centre.

INTRODUCTION AND AIMS: Coeliac disease (CD) was believed to be a childhood disease while it can affect any age.

AIM: to evaluate the prevalence of CD in elderly population, recording the main clinical features of this group respect to young patients.

METHODS: We retrospectively analysed the prevalence of CD in an elderly population from 1970 to 2015. We divided patients into three age-groups (group A: 18-34 years; group B: 35-64 years; group C: ≥65 years) and compared them regarding baseline anthropometric and serological variables, clinical features at diagnosis, diagnostic mode, associated autoimmune diseases, and CD-related neoplastic complications.

RESULTS: We made 2812 CD diagnoses in adults: 2.5% of them were ≥65 years at diagnosis. When comparing the three groups, we found no differences in sex, haemoglobin, serum iron, albumin, and anti-tissue transglutaminase (anti-tTG) (p = NS) while as expected, we found higher values of cholesterol, glycaemia, and triglycerides in older patients (p < 0.0001). Elderly had a higher risk of being diagnosed with malabsorption symptoms compared to younger patients (OR 2.20, 95%CI 1.3-3.74). No difference in the risk of autoimmune CD-related diseases was seen among groups. Furthermore, we observed 16 neoplastic complications, 13 of them happened in the patients diagnosed with CD aged 35-64 years. The number of CD diagnoses increased over time, particularly in elderly.

CONCLUSION: CD diagnosis in elderly population is quite uncommon although not rare. Elderly CD patients have a higher risk of being diagnosed with malabsorption symptoms than younger patients but without increased risk of autoimmune and neoplastic complications.
