What this trial studies

This study aims to assess the prevalence of bronchiectasis in adults with primary humoral immunodeficiency, including common variable immunodeficiency and other related conditions. It involves conducting blood tests and chest CT scans to identify the presence of bronchiectasis, which can often be asymptomatic but significantly impacts morbidity and mortality. The study seeks to establish a better understanding of the relationship between immunodeficiency and bronchiectasis, as well as to identify potential predictive factors for its development. By improving diagnosis and management, the study hopes to enhance patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include adult patients diagnosed with primary humoral immunodeficiency, such as common variable immunodeficiency or IgG subclass deficiency.

Not a fit: Patients under 18 years of age or those with conditions that prevent CT scans, such as claustrophobia or obesity, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnosis and management of bronchiectasis in patients with primary immunodeficiency, potentially reducing morbidity and mortality.

How similar studies have performed: While the prevalence of bronchiectasis in primary immunodeficiency has been noted in various studies, this specific investigation into its prevalence and predictive factors is novel.
