Recurrent pneumococcal pneumonia in an HIV-positive patient with lymphoid interstitial pneumonitis.

Lymphoid interstitial pneumonitis (LIP) is a rare complication of AIDS in adults. Patients with AIDS and LIP are at high risk for bacterial pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, and Staphylococcus aureus. We have described an HIV-positive patient with LIP complicated by recurrent pneumonia due to Streptococcus pneumoniae; recurrence was apparently prevented by maintenance penicillin therapy.
