    ObjectiveThe aim of this study was to compare rates and severity of recurrent acute diverticulitis in patients with and without solid organ transplant.BackgroundImmunocompromised solid organ transplant recipients have been considered higher risk for both recurrence and severity of acute diverticulitis. Current guidelines recommend an individualized approach for colectomy in these patients, but these are based on single-center data.MethodsWe identified patients with acute diverticulitis using the Merative MarketScan commercial claims data from 2014 to 2020. Patients were classified by history of solid organ transplant. The primary outcome was recurrence of acute diverticulitis with an associated antibiotic prescription ≥60 days from the initial episode. Secondary outcomes included hospitalization, colectomy, and ostomy in patients with recurrence. Analyses used inverse probability weighting to adjust for imbalances in covariates.ResultsOf 170,697 patients with evidence of acute diverticulitis, 442 (0.2%) had a history of solid organ transplantation. In the weighted cohort, among people who had not been censored at 1 year (n=515), 112 (22%; 95% CI: 20%-25%) experienced a recurrence within the first year. Solid organ transplantation was not significantly associated with a risk of recurrence (hazard ratio=1.19; 95% CI: 0.94-1.50). There was also no statistically significant difference in the hospitalization rate for recurrent diverticulitis. Restricting the analysis to hospitalized recurrences, there was no statistically significant difference observed in either length of stay or discharge status.ConclusionsIn this national analysis of commercially insured patients with acute diverticulitis we found no statistically significant differences in recurrence between those with and without a history of solid organ transplant. We do not support an aggressive colectomy strategy based on concern for increased recurrence rate and severity in a solid organ transplant population.Copyright © 2023 Wolters Kluwer Health, Inc.
