[Plasma exchange in polyradiculoneuritis in AIDS]

Plasma exchange was used in three cases of peripheral neuropathy of polyradiculoneuritis type in patients with AIDS. The neurologic lesion in the first case was due to a cytomegalovirus, and plasma exchange appeared to provide additional benefits (to antiviral treatment) during the first attack of polyradiculoneuritis. The peripheral neurologic disorders were probably related to the HIV itself in the other two cases, and plasma exchange was carried out only briefly because of the seriousness of the situation, which was unaffected. Although plasma exchange is possible, if particular technical precautions are taken, in patients with AIDS, the present series is too small for valid scientific evaluation.
