CDI is a major cause of morbidity and mortality in older adults, particularly over 65 years. Recurrent CDI leads to higher mortality and prolonged, debilitating illness. Case Presentations: This article presents two patients, aged over 80 years old, who developed recurrent CDI causing complicated and prolonged treatment courses. Patient 1 required an extended course of antibiotics for treatment of discitis and a congruent psoas abscess. Patient 2 developed CDI after multiple short courses of antibiotics for urinary tract infections (UTIs) in the context of multiple comorbidities. Both patients experienced three distinct episodes of CDI and were treated in collaboration with microbiology specialists. Following the third episode, both were successfully treated with oral capsule faecal microbiome transplants (FMTs). Their cases highlight the challenge of balancing systemic antibiotic use against CDI risk. Discussions: These cases underscore known risk factors for recurrent CDI, including advanced age and prolonged antibiotic exposure. Recurrence rates in patients over 65 can reach 58%. The British Society of Gastroenterology and Healthcare Infection Society support the use of FMTs in recurrent cases. Environmental decontamination, including terminal cleaning with sporicidal agents, is critical in reducing reinfection in hospital settings. Conclusions: Recurrent CDI in elderly patients reflects a complex interplay between infection control and managing comorbidities. New guidelines suggest that FMTs can significantly reduce morbidity and mortality. These cases emphasise the need for individualised, multidisciplinary care, adherence to guidelines, and further research to improve safe, effective CDI management in older adults.<\/jats:p>","DOI":"10.3390\/geriatrics10060158","type":"journal-article","created":{"date-parts":[[2025,12,2]],"date-time":"2025-12-02T12:39:43Z","timestamp":1764679183000},"page":"158","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Challenges and Strategies in Managing Recurrent Clostridioides difficile Infection in Older Adults"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-5965-8808","authenticated-orcid":false,"given":"Imaan","family":"Hirji","sequence":"first","affiliation":[{"name":"Royal Surrey NHS Foundation Trust, Guildford GU2 7XX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Divya","family":"John","sequence":"additional","affiliation":[{"name":"Royal Surrey NHS Foundation Trust, Guildford GU2 7XX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeena","family":"Jith","sequence":"additional","affiliation":[{"name":"Royal Surrey NHS Foundation Trust, Guildford GU2 7XX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiro","family":"Khoshnaw","sequence":"additional","affiliation":[{"name":"Royal Surrey NHS Foundation Trust, Guildford GU2 7XX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Myooran","family":"Ganeshananthan","sequence":"additional","affiliation":[{"name":"Royal Surrey NHS Foundation Trust, Guildford GU2 7XX, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,2]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Clostridium, Clostridioides, and Other Clostridia","volume":"12","author":"Kuijper","year":"2023","journal-title":"ClinMicroNow"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"273","DOI":"10.1007\/s40121-024-00919-0","article-title":"A Systematic Literature Review on Risk Factors for and Timing of Clostridioides Difficile Infection in the United States","volume":"13","author":"Eeuwijk","year":"2024","journal-title":"Infect.
