Abstract
Background. The literature and anecdotal evidence associate the resolution of radiographic findings of lymphocytic interstitial pneumonitis (LIP) with a decline in immune and clinical status of human immunodeficiency virus (HIV) infected children. Objective. As our clinical impression was the opposite, we sought to elucidate this contradiction. Materials and methods. Of 52 pediatric patients infected with the HIV currently being followed at our institution, 20 (38.5 %) carried the diagnosis of LIP and 13 (65 %) of these have had complete resolution of radiographic findings of LIP. We retrospectively reviewed the chest radiographs, CD4 counts, and clinical history of these 13 patients. Results. Of the 13 patients who had resolution of radiographic findings, 11 (84.6 %) had no significant change in CD4 count at the time of resolution and remained clinically stable during a mean follow-up period of 32 months. Two patients (15.3 %) developed severe CD4 lymphocytopenia at the time of resolution of LIP, but clinically remained stable. None of these 13 patients had a recurrence of LIP, even with subsequent increases in CD4 count. Conclusion. We suggest that in contradiction to previously published data, resolution of LIP on chest radiographs is not an indicator for poor prognosis for the HIV-infected pediatric patient.
