# Recurrent Clostridium difficile Infections in a Patient With Ulcerative Colitis: A Case Report

## TL;DR

An elderly patient with ulcerative colitis experienced multiple Clostridium difficile infections despite antibiotic treatments, highlighting the challenges in managing this condition in high-risk patients.

## Contribution

This case report emphasizes the severity and recurrence of CDI in elderly UC patients and suggests the need for alternative treatments like FMT.

## Key findings

- An elderly UC patient had three CDI episodes during a four-month hospitalization.
- Standard antibiotic treatments failed to prevent CDI recurrence in this patient.
- The case underscores the need for alternative therapies like FMT in managing recurrent CDI.

## Abstract

Clostridium difficile infection (CDI) poses a substantial clinical challenge, especially in patients with inflammatory bowel disease (IBD), particularly ulcerative colitis (UC). Patients with UC are at greater risk of CDI and tend to experience a more severe disease course and higher rates of recurrence than the general population. We report a case of an elderly man in his early 90s with a long-standing history of UC treated with mesalazine, who had a prior hospitalization for hyponatremia and a history of CDI. During his most recent four-month hospitalization, he developed three separate episodes of CDI, confirmed by stool PCR and toxin assays. Despite treatment with vancomycin, metronidazole, and fidaxomicin in succession, he experienced recurrent episodes of CDI that ultimately progressed to septic shock and death. This case highlights the nature of recurrent CDI in this patient population and the complexity and increased morbidity associated with its management in elderly patients with UC. It underscores the importance of careful evaluation of underlying risk factors, judicious antibiotic use, and consideration of alternative treatment modalities, such as faecal microbiota transplantation (FMT), for the prevention of recurrent CDI.
