Brief Summary

Death in Ataxia telangiectasia (A-T) is usually due to cancer or chronic lung failure around 20 years of age. Despite low lymphocyte counts (CD3, CD4, CD8 and CD19), IgA and IgG subclass deficiency opportunistic and acute severe respiratory infections are rare. The prevailing wisdom is that an immunoglobulin replacement therapy is not necessary in most of the patients. However no placebo controlled trials have been performed so far. The aim of this trial was to investigate the prevalence of mild and severe respiratory infections and / or chronic cough in classical A-T patients compared to healthy controls.

Study Arms (2)

Ataxia Telangiectasia

ACTIVE COMPARATOR

All A-T patients presented for 3 study visits. In all visits patients had a clinical examination, a blood collection and a lung function measurement. Furthermore symptom diaries were distributed and collected on these visits.

Procedure: Blood collectionProcedure: Lung function measurementBehavioral: Symptom diary

Healthy Control

ACTIVE COMPARATOR

All healthy controls presented for 3 study visits. In all visits patients had a clinical examination and a lung function measurement. Furthermore symptom diaries were distributed and collected on these visits.

Procedure: Lung function measurementBehavioral: Symptom diary

Interventions

In all patients with Ataxia telangiectasia blood was collected at each visit date to determine blood count, lymphocyte subpopulation count and immunoglobulin levels in serum (IgA, IgG, IgM, IgE), as well as alpha feto protein (AFP).

Ataxia Telangiectasia

In all patients - Ataxia telangiectasia and healthy controls - a lung function measurement was done to determine vital capacity (VC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF) and Tiffenau index.

Ataxia TelangiectasiaHealthy Control
Symptom diaryBEHAVIORAL

All patients - Ataxia telangiectasia and healthy controls - were requested to keep a symptom diary for the months September to March of the years 2012/2013 and 2013/2014 to determine days with symptoms as coughing during day and night, cold and fever, as well missing days at kindergarten/school/work, intake of medication (especially antibiotic treatment) and hospitalisations.
