Background:

Common variable immunodeficiency (CVID) is the most common primary symptomatic humoral immunodeficiency in adults. Antibody deficiency entails higher susceptibility to sinopulmonary infections and bronchiectasis formation, which is related to increased mortality. Scales have been established to assess the degree of severity of bronchiectasis in order to predict outcomes such as mortality, exacerbations and hospitalizations.

Objective:

To determine bronchiectasis severity in adult patients with common variable immunodeficiency using the Brief Symptom Inventory scale.

Method:

Cross-sectional study in adult population diagnosed with common variable immunodeficiency and attended to at the Mexican Institute of Social Security National Medical Center Siglo XXI Specialty Hospital.

Results:

Bronchiectasis severity according to the Brief Symptom Inventory was mild in 60% of patients and moderate in 40%. Statistically significant differences were found for body mass index, number of affected lobes and type of bronchiectasis (p < 0.001).

Conclusions:

Using bronchiectasis severity scales in patients with common variable immunodeficiency is indispensable for clinical and therapeutic decision making; however, determining the most appropriate instrument to assess bronchiectasis severity in this population is necessary.
