Gastrointestinal Presentations of Common Variable Immunodeficiency: Hiding in Plain Sight

Area of Science:

• Immunology
• Clinical Medicine
• Gastroenterology

Background:

• Primary immunodeficiency disorders (PIDs) typically manifest in childhood with recurrent infections.
• Common variable immunodeficiency (CVID) is the most frequent symptomatic PID, often diagnosed in adulthood.
• Gastrointestinal symptoms are common in CVID, frequently intractable and complicating diagnosis.

Purpose of the Study:

• To highlight the diagnostic challenges of Common Variable Immunodeficiency (CVID) in adults.
• To emphasize the importance of recognizing CVID beyond its typical childhood onset.
• To underscore the role of gastrointestinal manifestations in CVID diagnosis.

Main Methods:

• Review of clinical presentations of Primary Immunodeficiency Disorders.
• Analysis of diagnostic delays in Common Variable Immunodeficiency.
• Correlation of gastrointestinal symptoms with PID diagnosis.

Main Results:

• CVID diagnosis is often delayed due to its diverse clinical manifestations.
• Recurrent infections, particularly in the respiratory and gastrointestinal tracts, are key indicators.
• Intractable gastrointestinal issues are a significant feature in adult CVID patients.

Conclusions:

• A high index of clinical suspicion is crucial for diagnosing CVID in adults.
• Early recognition and diagnosis of CVID can prevent long-term complications.
• Understanding the varied presentation of CVID, including GI symptoms, is essential for timely intervention.
