The role of lung biopsy in children with perinatally acquired AIDS.

Abstract

There is a need for a rapid and efficacious method of diagnosis of pulmonary infiltrates in perinatal HIV infection. However, controversy still exists about which method--open lung biopsy (OLB) versus bronchoscopic techniques--is the best for this population. We present our results with OLB in 24 children with HIV-related lung disease. Over a 6-year period, 27 OLBs were performed on 24 children with diagnosis of HIV infection. The procedures were performed under general anesthesia using a limited anterolateral thoracotomy. Suspicious areas were removed with the autostapler. The specimens were studied for the presence of non-infectious as well as bacterial, viral, fungal, and mycobacterial diseases. There were no operative deaths related to the procedure. Morbidity was limited to prolonged but self-resolving air leaks in two patients (8.3%). Five hospital deaths occurred between 3 and 12 weeks postoperatively and 11 late deaths between 3 months and 6.5 years. All deaths were related to AIDS. Eight patients (33.3%) are still alive 2 to 8 years postoperatively. A total of 43 pathologies were found in 27 specimens. A positive pathologic finding was obtained in all patients, with two patients having nonspecific minimal changes. This resulted in a change of therapy in all but one case. The technique of OLB in children with AIDS is safe and simple. It should be performed early in the course of the disease and, a careful selection of candidates can minimize the incidence of complications.
