Non-specific gastrointestinal features: Could it be Fabry disease?

Area of Science:

• Gastroenterology
• Rare Diseases
• Genetics

Background:

• Non-specific gastrointestinal symptoms like pain, diarrhea, nausea, and vomiting can be early indicators of Fabry disease.
• The rarity and varied presentation of Fabry disease often lead to diagnostic delays and misdiagnoses, mimicking common conditions like IBS or IBD.
• Recognizing Fabry disease as a differential diagnosis for unexplained GI symptoms is critical for timely intervention.

Purpose of the Study:

• To highlight the importance of considering Fabry disease in patients with non-specific gastrointestinal symptoms.
• To emphasize the diagnostic methods for Fabry disease in affected individuals.
• To underscore the benefits of early, disease-specific treatment for improving clinical outcomes.

Main Methods:

• Clinical evaluation of non-specific gastrointestinal symptoms.
• Diagnostic confirmation through alpha-galactosidase A enzyme levels (men) and genetic mutation analysis (women).
• Review of treatment options including enzyme replacement therapy and chaperone therapy.

Main Results:

• Fabry disease can present with gastrointestinal symptoms mimicking more common disorders.
• Diagnostic delays are frequent due to the disease's complex presentation.
• Early initiation of enzyme replacement therapy or chaperone therapy improves long-term outcomes, including gastrointestinal manifestations.

Conclusions:

• Specialists should consider Fabry disease in the differential diagnosis of unexplained gastrointestinal symptoms.
• Prompt diagnosis via enzyme assays or genetic testing is essential.
• Early and appropriate treatment, such as enzyme replacement therapy, can significantly improve patient prognosis and manage GI symptoms effectively.
