A patient with recurrent infections and diarrhea presented with symptoms mimicking Crohn's disease. A nitroblue tetrazolium (NBT) test suggested Chronic Granulomatous Disease (CGD), complicating treatment due to sepsis risk with immunosuppressants.
Area of Science:
- Immunology
- Gastroenterology
- Genetics
Background:
- Recurrent infections and chronic diarrhea can indicate underlying immune deficiencies.
- Distinguishing inflammatory bowel disease from other granulomatous conditions is crucial for appropriate management.
Observation:
- A young female patient experienced recurrent infections and profuse diarrhea.
- Previous nitroblue tetrazolium (NBT) testing revealed absent dye reduction.
- Clinical, biochemical, radiological, and endoscopic evaluations suggested Crohn's disease.
Findings:
- The NBT test results were highly indicative of Chronic Granulomatous Disease (CGD).
- CGD can present with granulomatous colitis, mimicking Crohn's disease.
- Immunosuppressive therapy for the presumed condition led to recurrent sepsis.
Implications:
- This case highlights the importance of considering CGD in patients with granulomatous colitis and recurrent infections.
- Diagnostic challenges arise when symptoms overlap between immune deficiencies and inflammatory bowel disease.
- Careful management is required to balance immunosuppression and infection risk in CGD patients presenting with gastrointestinal symptoms.

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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
