Interrelationships among quantity of human cytomegalovirus (HCMV) DNA in blood, donor-recipient serostatus, and administration of methylprednisolone as risk factors for HCMV disease following liver transplantation
Abstract
Longitudinal analysis of 162 liver transplant recipients identified 51 patients who were viremic. Virus load was determined in 47 of these patients using quantitative-competitive polymerase chain reaction. Peak virus load was significantly higher in 20 symptomatic patients than 27 asymptomatic patients (P < .0001). Elevated virus load, donor seropositivity, and total methylprednisolone dosage were risk factors for human cytomegalovirus (HCMV) disease (odds ratio [OR], 2.22/0.25 log10 increase in virus load, P = .001; OR, 4.11, P = .05; OR, 1.30/1-g increment in methylprednisolone, P = .01). Methylprednisolone and virus load were independent risk factors in a multivariate analysis (OR, 2.70/1-g increase, P = .003; OR, 1.61/0.25 log10 increase, P = .03, respectively). Virus loads of 10(4.75)-10(5.25) genomes/mL of blood were associated with an increased disease probability; the latter was shifted to lower virus loads with increasing quantities of methylprednisolone. These data illustrate the central role of virus load in HCMV pathogenesis.
