AB In AIDS patients cytomegalovirus (HCMV) retinitis is one of the most
frequent opportunistic infections. Antiviral therapy aims at preserving
vision as long as possible, but more and more HCMV isolates are proving
to be resistant to ganciclovir (GCV) and foscarnet (PFA) in vitro. We
tested whether desferrioxamine (DFO), an iron chelator with antiherpetic
activity, can inhibit clinical virus isolates and laboratory strains.
Clinical isolates were obtained from urine samples of AIDS patients with
HCMV retinitis. The concentrations of DFO required for 50% and 90%
reduction of the production of HCMV in several HCMV strains ranged from
3.1 to 4.9 microns and from 14.2 to 17.3 microns, respectively,
Inhibitory effects of DFO on HCMV replication were completely prevented
by co-incubation with stoichiometric amounts of FE3+. CASE REPORTS: DFO
was administered by daily dose of 1 g i.v. to a patient with AIDS in
whom HCMV retinitis continued to progress despite combination therapy
with GCV and PFA. The addition of DFO to the combination inhibited
progression of the disease. No relapse of HCMV retinitis was seen with 3
months of DFO therapy. The treatment was free of side effects.
