title: Resolution of lymphocytic interstitial pneumonia in a human immunodeficiency virus-infected adult following the start of highly active antiretroviral therapy.
abstract: A case of human immunodeficiency virus (HIV)-associated lymphocytic interstitial pneumonia is described, in which improvement occurred soon after starting antiviral therapy. A 20-y-old black female with HIV infection (CD4+ count 228 x 10(6) cells and plasma viral load 379,670 copies/ml) showed radiological signs of reticulonodular infiltrates of the lungs and pulmonary functional tests indicative of a severe restrictive syndrome. Bronchoalveolar and blood cultures yielded no organism and transbronchial biopsy disclosed findings consistent with lymphocytic interstitial pneumonia. After 4 weeks on triple HIV combination therapy, she was well and respiratory tests had normalized. Six months later, a computed tomographic scan of the chest showed only residual alterations. Despite a good sirological response to treatment, no significant immune recovery occurred over a 2 y follow-up.
