AIDS-related airway disease

Area of Science:

• Pulmonology
• Infectious Diseases
• Radiology

Background:

• Airway disease is an underrecognized pulmonary manifestation in human immunodeficiency virus (HIV)-positive patients.
• Lack of familiarity with evolving HIV-related pulmonary disease patterns and limitations of chest radiography contribute to this deficit.
• Accurate diagnosis of airway disease is essential for prompt and effective treatment.

Purpose of the Study:

• To highlight the importance of airway disease in HIV-positive patients.
• To emphasize the diagnostic utility of computed tomography (CT) in identifying and differentiating airway diseases.
• To guide the diagnosis and management of pulmonary abnormalities in HIV-positive individuals.

Main Methods:

• Review of imaging findings related to airway disease in HIV-positive patients.
• Emphasis on the role of CT in detecting small airways disease, infectious bronchitis, and bronchiolitis.
• Discussion of CT's ability to differentiate various infectious and noninfectious pulmonary diseases.

Main Results:

• Chest radiography has limitations in identifying and differentiating airway disease in HIV-positive patients.
• CT is accurate in detecting airway disease, including small airways disease, which may be occult on radiography.
• CT aids in distinguishing infectious conditions (e.g., bronchitis, bronchiolitis) from other pulmonary diseases and guides diagnosis of Kaposi's sarcoma, mycobacterial/fungal infections, and lymphoma.

Conclusions:

• Airway disease is a significant, often overlooked, pulmonary complication in HIV-positive patients.
• CT imaging is invaluable for the accurate diagnosis and differentiation of airway diseases and other pulmonary pathologies in this population.
• Utilizing CT findings can lead to timely and appropriate therapeutic interventions, improving patient outcomes.
