Abstract
Aim:
To determine the frequency of sinopulmonary infections, detect changes in the respiratory system, and measure functional capacity of the lungs in our patients with humoral immunodeficiency.
Material and Methods:
Fifty-six patients with humoral immunodeficiency were enrolled in this study. The clinical, laboratory, and radiologic data, and pulmonary function tests of the subjects were evaluated from their file records, retrospectively.
Results:
The distribution of our patients was as follows: 25 patients had common variable immune deficiency, three patients had X-linked agammaglobulinemia, five patients had hyper immunoglobulin M syndrome, 19 patients had deficiency of immunoglobulin G subset, and four patients had selective immunoglobulin A deficiency. The most common symptom of the patients was chronic cough (n=47, 83.9%). The most common pathologies on high-resolution computed tomography of the chest were atelectasis and bronchiectasis (27.7%). The most common pathology in pulmonary function tests was the presence of moderate obstructive patterns along with restrictive patterns (n=6,12.5%). The FEV 1, FVC, and FEF 25–75 values were significantly lower in patients with common variable immunodeficiency compared with the patients who had IgG subset deficiencies (p=0.001, p=0.01, p=0.01). Among the patients who were treated with intravenous immunoglobulin, the age at the diagnosis of immunodeficiency was higher in patients with bronchiectasis (14.2±8.4 years) compared with those without bronchiectasis (10.1±11.4 years) (p=0.04).
Conclusion:
Clinical findings are not sufficient to monitor the structural and functional changes in the respiratory system, and patients should be evaluated using high-resolution computed tomography of the chest and pulmonary function tests.
