Background: Pneumothorax is a not uncommon complication of advanced Hr
infection, and may prove difficult to manage in view of its recalcitr
ant and recurrent nature. In this group where immunosuppression and re
duced life expectancy are a feature, standard protocols are often aban
doned in favour of a more conservative approach. This is often unsucce
ssful. Methods: Patients attending the Department of Genitourinary Med
icine, Chelsea and Westminster Hospital who sustained pneumothorax bet
ween 1988 and 1992 were identified retrospectively and their notes rev
iewed. Results: Fifteen patients were identified of whom three had pos
t-procedural pneumothoraces. In the remaining 12 patients, 10 had prev
iously had Pneumocystic carinii pneumonia (PCP), whilst all 12 had som
e evidence to suggest current PCP (seven proven, five presumptive). In
those six patients with a single, unilateral pneumothorax, four were
managed successfully with intercostal drainage alone (one patient died
early, one required pleurectomy). In those with recurrent pneumothora
ces or pneumothoraces that did not respond to prolonged intercostal dr
ainage, failure of medical treatment was judged to have occurred and s
urgery was performed. Overall, conservative management failed in 7/11
patients. Conversely surgery resulted in resolution in 7/7 with recurr
ence seen in one individual. Median survival was similar in the two gr
oups. Conclusions: Pneumothorax in patients with AIDS is associated wi
th a high rate of intercurrent PCP; a low threshold for treating this
infection presumptively is indicated. Intercostal drainage was success
ful in patients with a single, unilateral pneumothorax. However, in pa
tients with recurrent or bilateral pneumothorax extended periods on in
tercostal drainage were uniformly unsuccessful. Early surgical referra
l should be considered in this group.
