[Severe acute colitis: two fatal cases in Dakar]
1Hépato-gastro-entérologie, hôpital général de Grand-Yoff, Dakar, Sénégal.
Severe acute colitis (SAC), a life-threatening complication of ulcerative colitis (UC), is rarely reported in sub-Saharan Africa. This report details two fatal SAC cases in Senegalese patients, highlighting diagnostic challenges in endemic infectious colitis regions.
Area of Science:
- Gastroenterology
- Internal Medicine
- Public Health
Background:
- Inflammatory bowel disease (IBD), particularly ulcerative colitis (UC), can lead to severe acute colitis (SAC), a life-threatening condition.
- IBD is historically considered uncommon in sub-Saharan Africa, with limited data on SAC prevalence and management in this region.
Observation:
- Two fatal cases of SAC in Senegalese patients with UC are presented, occurring in Dakar.
- Both patients presented with chronic dysenteric syndrome; initial management with antibiotics for suspected infectious colitis proved ineffective.
- Despite interventions including parenteral corticosteroids, both patients experienced severe complications, including intestinal perforation and toxic megacolon, leading to fatal outcomes.
Findings:
- The cases underscore the potential for SAC in UC patients even in regions where IBD is perceived as rare.
- Delayed or missed diagnosis of SAC, potentially due to the predominance of infectious colitis, contributed to poor outcomes.
- Treatment challenges included the need to differentiate SAC from infectious colitis and the accessibility of advanced care.
Implications:
- Clinicians in subtropical regions should maintain a high index of suspicion for SAC in patients with UC, especially those presenting with dysenteric symptoms.
- Early and appropriate management of SAC is crucial, even amidst diagnostic uncertainty and potential co-existing infections.
- Improved diagnostic capabilities and timely therapeutic interventions are essential for reducing mortality associated with SAC in underserved regions.

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...

Acute Pancreatitis I: Introduction
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:
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...
