Abstract
Key summary points: Aim: To investigate the association between Clostridioides difficile recurrence and 6-month mortality in older inpatients and the risk factors for Clostridioides difficile recurrence after hospital discharge.Findings: Clostridioides difficile recurrence is associated with a higher risk of 6-month mortality. Vancomycin treatment during the first infectious episode was associated with lower recurrence rate, as compared to metronidazole.Message: This research showed as that Clostridioides difficile recurrence may itself be a marker of frailty and vulnerability in older people. The use of vancomycin as first-line therapy, compared to metronidazole, may reduce the likelihood of future recurrence, regardless of the disease severity.
Purpose: The prevalence of Clostridioides difficile infection in older and frail population is extremely high and adverse outcomes, including future recurrences and premature mortality, are common. Nonetheless, the clinical risk profile for Clostridioides difficile recurrence in older people is still controversial. We aimed to investigate: 1) the association between Clostridioides difficile recurrence and 6-month mortality; 2) the risk factors for Clostridioides difficile recurrence after hospital discharge.Methods: This is a retrospective study on adults with a first episode of Clostridioides difficile infection admitted to all Internal Medicine and Geriatrics Units of the University Hospital of Ferrara (Italy) between January 2018 and December 2020. For each patient, sociodemographic, clinical and laboratory data were collected through hospital database system. The primary and secondary outcomes were mortality and recurrence within 6 months from the first infectious episode, respectively.Results: The mean age of the 386 enrolled patients was 77.8 years; 61.7% were females. Twelve percent patients had Clostridioides difficile recurrence and 32.1% patients died during the 6-month follow-up. At Cox analysis, after adjustment for the potential confounders, participants with recurrence reported a twofold risk of death compared to those without recurrence (HR, 95% CI 2.45, 1.59–3.78). Compared to patients treated with metronidazole, those treated with vancomycin showed a lower risk of recurrence (log-rank p < 0.001).Conclusion: Clostridioides difficile recurrence is associated with a higher risk of mortality and it may itself be a marker of frailty and vulnerability. Vancomycin treatment during the infectious episode was associated with lower recurrence rate, as compared to metronidazole.
