OBJECTIVES: Congenital human cytomegalovirus (cCMV) is a leading cause of pediatric hearing loss. Recent literature has suggested that valganciclovir (VGCV) therapy can improve hearing outcomes. The objective of this study was to evaluate the long-term hearing outcomes among symptomatic CMV patients treated with VGCV.
METHODS: A retrospective chart review of symptomatic CMV patients treated with VGCV was completed. The primary endpoint was the change in best ear hearing scores prior to treatment and after follow-up audiograms. A paired-sample t-test was used to evaluate the data.
RESULTS: A total of 16 children were included in the study and participants were followed for an average of 3.2 years. There was a measurable worsening, but not a statistically significant change in the best ear hearing scores, where the mean change was 11.9 dB (p-value = 0.070). However, 14/16 patients (87.5%, p-value<0.001) were found to have clinically significant worsening of hearing. The mean change in hearing scores for the left and right ear was 14.2 dB (p-value = 0.023) and 15.5 dB (p-value = 0.032), respectively. Mean elapsed time for progressive loss was 2.6 ± 0.2 years. When comparing the better or worse ear, there was no pattern for which ear deteriorated earlier or more frequently.
CONCLUSIONS: Our data did show a measurable, but not a statistically significant worsening outcome in best ear hearing. There was a significant change in both left and right ear hearing. Our results suggest that VGCV may provide only a short-term improvement in hearing outcomes; however, these preliminary post-hoc findings suggest the need for a more rigorous evaluation.
