Cystic Fibrosis, Common Variable Immunodeficiency and Aspergers Syndrome: an Immunological and Behavioural Challenge

Introduction: Cystic fibrosis (CF) is of particular importance in Ireland as the Irish population has both the highest incidence (2.98/10,000) and the highest carrier rate (1 in 19) in the world. Primary immunodeficiency has not been previously reported as co-existing with CF.

Case Report: We report a unique case of CF associated with a primary immunodeficiency syndrome--common variable immunodeficiency (CVID).

Discussion: Our patient has CF, CVID and the additional comorbidity of Aspergers syndrome. The challenges inherent in diagnosing and treating such a case are outlined herein and the successful management of this case is evidenced by the well-preserved lung function of our patient.
