A CASE OF VERY EARLY ONSET INFLAMMATORY BOWEL DISEASE, CHRONIC LUNG DISEASE, AND RECURRENT INFECTIONS

Very early onset inflammatory bowel disease (VEOIBD) may correlate with multiple immunodeficiencies, including severe combined immunodeficiency (SCID), common variable immunodeficiency (CVID), chronic granulomatous disease (CGD), Wiskott-Aldrich syndrome (WAS), and IL-10 signaling defects. It may be difficult to differentiate between intestinal inflammation and immune dysfunction leading to systemic symptoms and elevated inflammatory markers. This patient, a 5-year-old male with very early onset Crohn's disease, chronic lung disease, 1p36 duplication, failure to thrive, eczema, and systemic infections including Candidemia, Klebsiella bacteremia, histoplasmosis, recurring pneumonia, multiple upper respiratory and sinus infections, and recurring IBD flares, presented due to concern for underlying primary immunodeficiency.
