Severe airflow obstruction in vertically acquired HIV infection.

ABSTRACT

It is becoming increasingly clear that human immunodeficiency virus (HIV) infection, either independently or in concert with opportunistic infections like pulmonary tuberculosis, is a risk factor for the development of chronic airflow limitation. In the majority of patients the etiology of this obstructive ventilatory defect is multifactorial. Post-infectious obliterative bronchiolitis, post-tuberculous lung damage (including bronchiectasis), immune reconstitution and the direct effects of HIV viral infection may all play a role. With increases in life expectancy and decreases in infectious complications in patients taking antiretroviral medications, the importance of HIV-associated chronic lung disease as a cause of pulmonary disability is likely to increase. This is particularly relevant in regions like sub-Saharan Africa, where both HIV infection and tuberculosis are highly prevalent. Here, to illustrate the complexity of this interaction, we present the case of a 15-year-old girl with vertically acquired HIV infection, multiple episodes of pulmonary infection, and severe airflow obstruction.
