A case of flare syndrome.

The authors describe a case of severe CMV retinitis in a young adult AIDS patient who recovered following first a course of ganciclovir and then HAART. Six months after the initial episode while still under successful HAART, the patient developed an acute episode of retinitis despite a persistent significant improvement in the immunological picture and a very low level of CMV reactivation. The acute episode can be related to an enhanced individual reactivity to minor CMV replication.
