Unique Presentation of Common Variable Immunodeficiency: Enteropathy Unaccompanied by Infectious Phenotype

Abstract

Enteropathy is one of the rare manifestations of common variable immunodeficiency (CVID) as a predominant antibody deficiency. Proper diagnosis of this phenotype in CVID cases is difficult and may result in inaccurate assessment or incorrect management. Further, this misdiagnosis is more probable when noninfectious diarrhea is the only manifestation of CVID. We present herein a case with such an abstruse condition who was misdiagnosed as a celiac disease leading to delayed diagnosis of her primary immunodeficiency disease. We also offer a review on enteropathy manifestation in CVID patients.
