Özet
This study aimed to retrospectively evaluate the baseline and follow-up viral loads and viral clearance times in cases followed for asymptomatic and symptomatic congenital cytomegalovirus (cCMV) infection between August 2010 and August 2022. Among 93 cases, they had asymptomatic (n: 55) and symptomatic (n: 38). The median baseline blood viral load detected in the symptomatic cCMV (ScCMV) infection (13 054 IU/mL) was significantly higher than that of asymptomatic cCMV (AcCMV) infection (4636 IU/mL) (p < 0.013). There was no difference in median viral clearance times (75 and 90 days, respectively) in baseline viremic cases in the ScCMV and AcCMV infection groups. There were no differences in median baseline blood viral load (6930 IU/mL and 14 268 IU/mL, respectively) and median viral clearance times (75 and 85 days, respectively) between the 6-week and 6-month antiviral treatment group. No correlation was found between baseline blood viral load, clinical severity, and the number of systems involved. However, in initial viremic cases, the viral load threshold for a symptomatic case was 8856 IU/mL, with 85.7% sensitivity and 54.5% specificity.
