Ataxia telangiectasia is a multi-system disorder characterized by progressive cerebellar ataxia, malignancies, chronic pulmonary disease and immunodeficiency. The aim of our study was to determine the immune competence and prevalence of respiratory infections and/or chronic cough in classical A-T patients compared to age-matched healthy controls.
We recruited 20 classical A-T not treated by immunoglobulins and 21 healthy age-matched control patients. The caregivers were advised to keep a daily diary with the following items (daytime and nighttime cough, runny nose, fever), number of cold episodes, number of antibiotic treatments.
Patients with A-T showed significant differences compared to healthy controls in symptom score, daytime and nighttime cough, days with symptoms and missed days in kindergarten/school. Severe infections with hospitalization occurred rarely. Respiratory symptoms did not correlate with immunoglobulin levels in A-T patients.
Mild symptoms like chronic cough were present in A-T patients, possibly indicating ongoing silent crippling disease.
