Abstract:
Diarrhoea that occurs during or after recent travel is predominantly infectious in nature; however, in atypical or prolonged cases a broader range of aetiologies for diarrhoea must be considered, and a careful history and examination may reveal clues to more sinister causes of diarrhoea. We report two cases in which a recent travel history and a positive stool culture or polymerase chain reaction testing for bacterial pathogens delayed the diagnosis of ulcerative colitis. As a result of severe inflammatory bowel disease, colectomy was the final result in both cases. Early consideration of causes other than infection for traveller's diarrhoea may prevent unnecessary morbidity in young patients.
Insights
Travel-related diarrhea can mask serious conditions like ulcerative colitis. Promptly considering non-infectious causes beyond bacterial pathogens is crucial for early diagnosis and preventing severe outcomes in young travelers.
Area of Science:
- Gastroenterology
- Infectious Diseases
- Internal Medicine
Background:
- Diarrhea after travel is often infectious.
- Atypical or prolonged cases require broader etiological consideration.
- Travel history is key in diagnosing diarrhea.
Observation:
- Two cases presented with travel-related diarrhea.
- Diagnosis of ulcerative colitis was delayed by positive bacterial stool tests.
- Severe inflammatory bowel disease necessitated colectomy in both patients.
Findings:
- Bacterial pathogen identification in stool can mislead diagnosis.
- Focusing solely on infection can delay recognition of non-infectious causes.
- Ulcerative colitis can mimic infectious traveler's diarrhea.
Implications:
- Early consideration of non-infectious causes is vital for traveler's diarrhea.
- Prompt diagnosis can prevent severe morbidity and unnecessary colectomy.
- Integrated diagnostic approaches are needed for complex travel-related gastrointestinal issues.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
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...
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
