Antibiotic-associated colitis can be caused by Klebsiella oxytoca, particularly after clarithromycin use. This case highlights the risk of Klebsiella oxytoca-induced haemorrhagic colitis in patients treated with clarithromycin.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Microbiology
Background:
- Antibiotic-associated colitis is a known complication of certain antibiotics.
- Klebsiella oxytoca has been previously implicated in haemorrhagic colitis, particularly with ampicillin use.
Observation:
- A 67-year-old female with diabetes presented with symptoms of mucobloody diarrhea and abdominal pain.
- Stool cultures confirmed the presence of Klebsiella oxytoca.
- Colonoscopy revealed characteristic findings of haemorrhagic colitis.
Findings:
- The patient had recently completed a course of oral clarithromycin for an upper respiratory tract infection.
- This case demonstrates a link between clarithromycin and Klebsiella oxytoca-induced haemorrhagic colitis.
- The patient recovered with conservative management.
Implications:
- Clinicians should be vigilant for gastrointestinal symptoms in patients prescribed clarithromycin.
- Klebsiella oxytoca should be considered as a potential cause of antibiotic-associated haemorrhagic colitis, even with newer antibiotics like clarithromycin.
- This finding expands the spectrum of antibiotics associated with Klebsiella oxytoca-induced colitis.

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...
