This case highlights Crohn's disease presenting unusually as protein-losing enteropathy, causing edema and hypoalbuminemia. Early diagnosis is crucial for managing this rare inflammatory bowel disease complication.
Area of Science:
- Gastroenterology
- Internal Medicine
- Clinical Case Study
Background:
- Inflammatory bowel disease (IBD) can manifest with diverse extraintestinal and gastrointestinal symptoms.
- Protein-losing enteropathy (PLE) is an uncommon complication of IBD, characterized by excessive protein loss through the gastrointestinal tract.
- Serum hypoalbuminemia and edema are key clinical indicators of significant protein loss.
Observation:
- A 37-year-old woman presented with lethargy, breathlessness, and peripheral edema, initially attributed to iron deficiency anemia and hypoalbuminemia.
- Extensive investigations excluded renal, cardiac, and hepatic causes for her persistent hypoalbuminemia and edema over two years.
- Capsule endoscopy revealed small bowel ulceration, and subsequent analysis showed elevated fecal alpha-1 antitrypsin, indicating protein loss.
Findings:
- Histological diagnosis post-small bowel resection confirmed Crohn's disease as the underlying cause of the patient's symptoms.
- The clinical presentation was predominantly that of protein-losing enteropathy, a rare manifestation of Crohn's disease.
- This case underscores the importance of considering gastrointestinal causes for unexplained hypoalbuminemia and edema.
Implications:
- This case emphasizes the need to recognize protein-losing enteropathy as a potential, albeit uncommon, presentation of Crohn's disease.
- Early identification and management of PLE in Crohn's disease can prevent severe complications and improve patient outcomes.
- Further research into the pathophysiology and diagnostic challenges of PLE in IBD is warranted.

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...
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...

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...
