Pseudomembranous colitis (PMC) is rare in ulcerative colitis (UC) patients. This case highlights PMC development in a UC patient after antibiotic and corticosteroid treatment, emphasizing the need for prompt diagnosis and management.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Colorectal Surgery
Background:
- Ulcerative colitis (UC) is an inflammatory bowel disease.
- Pseudomembranous colitis (PMC) is typically caused by Clostridium difficile toxin (CD toxin).
- PMC is an uncommon complication in UC patients.
Observation:
- A 71-year-old woman with UC developed PMC after lumbar surgery, postoperative infection, and antibiotic treatment.
- Symptoms included diarrhea, bloody stools, and abdominal pain.
- Colonoscopy confirmed PMC in multiple colonic segments, with positive CD toxin stool tests.
Findings:
- The patient was treated with vancomycin (VCM) while continuing levofloxacin hydrate (LVFX) and prednisolone.
- Symptoms improved, and colonoscopy confirmed PMC resolution.
- Suspected causative agents included cefotiam hydrochloride, LVFX, and prednisolone.
Implications:
- PMC should be considered in UC patients experiencing gastrointestinal symptoms, especially those on antibiotics, immunosuppressants, or corticosteroids.
- Prompt investigation using colonoscopy and CD toxin testing is crucial for early diagnosis and treatment.
- This case underscores the importance of vigilance for PMC in immunocompromised or medically treated UC patients.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
