Abstract: PURPOSE: ) who underwent a surveillance and preemptive therapy protocol, compared to nonmismatch patients. METHODS: A review of patient records from January 2010 to December 2020 with follow-up to October 2023 was done. The protocol consisted weekly surveillance with CMV PCR starting 4 weeks after transplant continuing up until the patient seroconverts or up to 3 months posttransplant if the patient does not seroconvert. Valganciclovir was given for 2 weeks to those who seroconverted. RESULTS: Two hundred and twenty-one patients were included, and 23% were mismatched patients. Overall survival was not different between CMV groups (p = NS). Causes of death and morbidities were also not significantly different (p = NS). Sixty-six percent of mismatch patients seroconverted, and there was also a significantly older donor age in the seroconverted patients compared to nonseroconverted patients (41 ± 11 vs. 29 ± 12 years, p < 0.005), indicating a higher risk donor profile. A multivariate Cox regression including donor age showed that there was no increase in mortality in the seroconverted mismatches compared to nonmismatch patients (p = NS). CONCLUSIONS: There is no significant increased mortality or morbidity using a CMV surveillance and preemptive therapy protocol. The effect of donor age on seroconversion of mismatches requires further validation.
