In children, data from the literature find a higher prevalence of asthma in the population treated for HIV. Bronchial hyperreactivity, indicative of chronic inflammation and bronchial obstruction, is also present.

Screening for early peripheral obstruction could therefore make it possible to initiate appropriate anti-inflammatory treatment, if necessary, and early preventive management.

In adults chronically infected with HIV, there is an increased prevalence impaired respiratory function, with a greater occurrence of COPD than in the uninfected population. In children, data from the literature find a prevalence of greater atopy in the HIV-infected pediatric population. Furthermore, a bronchial hyperreactivity or even peripheral bronchial obstruction, indicative of a local chronic inflammation has been found in young adolescents treated since the birth for HIV infection in utero. Screening for early peripheral obstruction in HIV-infected adolescents could therefore make it possible to initiate, if necessary, a anti-inflammatory treatment, and early management to prevent the occurrence of impaired respiratory function in adulthood For this this single-center prospective study chose to perform respiratory function explorations with forced oscillometry with the Endpoint main factor of the peripheral obstruction the R5HZ parameter expressed in % predicted. Patients from 11 to 25 years to whom it was proposed added to that to answer a questionnaire of respiratory quality of life
