[Bronchiectasis severity in adult patients with common variable immunodeficiency]

Area of Science:

• Immunology
• Pulmonology
• Clinical Medicine

Background:

• Common variable immunodeficiency (CVID) is a primary humoral immunodeficiency common in adults.
• Antibody deficiency in CVID increases susceptibility to sinopulmonary infections and bronchiectasis, a condition linked to higher mortality.
• Established scales help assess bronchiectasis severity to predict outcomes like mortality and exacerbations.

Purpose of the Study:

• To evaluate bronchiectasis severity in adult CVID patients using the Brief Symptom Inventory (BSI) scale.

Main Methods:

• A cross-sectional study was conducted.
• Adult patients diagnosed with CVID and attending the Mexican Institute of Social Security National Medical Center Siglo XXI Specialty Hospital were included.

Main Results:

• Bronchiectasis severity was mild in 60% and moderate in 40% of CVID patients, as assessed by the BSI.
• Significant differences were observed in body mass index, number of affected lobes, and bronchiectasis type (p < 0.001).

Conclusions:

• Bronchiectasis severity scales are crucial for clinical and therapeutic decisions in CVID management.
• Further research is needed to identify the most appropriate instrument for assessing bronchiectasis severity in this specific patient population.
