The objectives of the study were to examine the clinical significance
of cytomegalovirus (CMV) culture results and drug susceptibilities in
CMV isolates from patients with AIDS-related CMV retinitis, Blood and
urine for CMV culture were obtained from 207 patients with newly diagn
osed CMV retinitis who were enrolled in a randomized trial comparing f
oscarnet and ganciclovir. Culture-positive rates at baseline were 45%
and 71% for blood and urine, respectively. Rates decreased 3- to 10-fo
ld after initiation of either treatment. Mortality was related to both
positive baseline blood and urine cultures; adjusted relative risks w
ere 1.97 and 2.03, respectively, Positive blood cultures at baseline w
ere associated with more rapid retinitis progression. Drug-resistant C
MV was found, over comparable follow-up periods on assigned treatment,
in 4 of 8 ganciclovir-assigned patients with persistent viremia and 0
of 5 foscarnet-assigned patients with persistent viremia, Results of
virologic assays of blood appear to be associated with clinical outcom
e of CMV retinitis.
