Background: Most of the hypogammaglobulinemic patients have a clinical history in favor of allergic respiratory disease. Nevertheless, in these patients the importance and prevalence of atopic disorders have not been completely explained.
Objectives: This study was aimed to evaluate atopic manifestations (dermatitis, allergic rhinitis and asthma) and pulmonary function in patients with hypogammaglobulinemia.
Patients and methods: We used the international study of asthma and allergies in childhood (ISAAC) questionnaire in forty-five patients diagnosed with hypogammaglobulinemia and spirometry was done in 41 patients older than 5 years.
Results: Spirometry results were normal in 21 (51%), and showed obstructive in 15 (37%) and restrictive pattern in 5 (12%) of the 41 patients who were evaluated. By the end of the study, asthma was diagnosed in nine (20%) patients and other atopies (rhinitis and dermatitis) identified in 10 (22%), and four (9%), respectively.
Conclusions: Atopic conditions should be investigated in the hypogammaglobulinemic patients and the prevalence in these patients may be higher than in normal population. Also, it is recommended to perform a pulmonary function test as a routine procedure in patients with hypogammaglobulinemia and atopy should be assessed in these patients.
