Abstract
BACKGROUND: Elderly-onset ulcerative colitis (EO-UC) is recognized as a distinct subpopulation of UC. To our knowledge, there have been no nationwide studies of EO-UC populations in the USA. AIMS: We aim to characterize differences in presentation at diagnosis and clinical course between EO-UC and adult-onset UC (AO-UC) patients in a national cohort. METHODS: Complete medical records of patients newly diagnosed with UC from October 2001 to October 2011 in the Veterans Affairs health system were obtained. Patients were followed until colectomy, death, or the end of the observation period on November 2015. EO-UC patients (age of diagnosis ≥65 years) were compared to AO-UC patients (age of diagnosis ≤40 years) with respect to demographic, severity, and therapeutic data. Statistical analysis was performed using JMP statistical software. RESULTS: We identified 836 newly diagnosed UC patients, of which 207 had EO-UC and 102 had AO-UC. The mean age of diagnosis was 72.4 years (EO-UC) and 32.9 years (AO-UC), with a mean 8-year follow-up period. The incidence of pancolitis at the time of diagnosis was similar between both groups (p = 0.67). There was no difference in steroid use (36.7 vs 45.1%, p = 0.1563), thiopurine use (19.3 vs 22.6%, p = 0.5081), and colectomy rates (6.3 vs 5.9%, p = 0.8911) between EO-UC and AO-UC populations. There was lower anti-TNF use in EO-UC patients compared to AO-UC patients (5.8 vs 14.7%, p = 0.0091). CONCLUSION: In this nationwide cohort, we found that the use of steroids, thiopurines, and colectomy was similar in both populations, while anti-TNF use was lower among the elderly.
