摘　　要：BACKGROUND Cytomegalovirus(CMV)prophylaxis with valganciclovir and ganciclovir is associated with elevated neutropenia and leukopenia risk in kidney transplant recipients,although the impact of these events on healthcare resource utilization(HCRU)and clinical outcomes is unclear.AIM To quantify clinical events and HCRU associated with neutropenia and leukope-nia among adults receiving valganciclovir and/or ganciclovir post-kidney trans-plantation.METHODS Adult kidney transplant recipients receiving valganciclovir and/or ganciclovir prophylaxis were identified in the TriNetX database from 2012 to 2021.Patient characteristics were evaluated in the 1-year period pre-first transplant.HCRU and adjusted event rates per person-year were evaluated in follow-up year 1 and years 2-5 after first kidney transplantation among cohorts with vs without neutropenia and/or leukopenia.RESULTS Of 15398 identified patients,the average age was 52.39 years and 58.70%were male.Patients with neutropenia and/or leukopenia had greater risk of clinical events for CMV-related events,opportunistic infections,use of granulocyte colony stimulating factor,and hospitalizations(relative risk>1 in year 1 and years 2-5).Patients with vs without neutropenia and/or leukopenia had higher HCRU in year 1 and years 2-5 post kidney transplantation,including the mean number of inpatient admissions(year 1:3.47 vs 2.76;years 2-5:2.70 vs 2.29)and outpatient visits(48.97 vs 34.42;31.73 vs 15.59,respectively),as well as the mean number of labs(1654.55 vs 1182.27;622.37 vs 327.89).CONCLUSION Adults receiving valganciclovir and/or ganciclovir prophylaxis post-kidney transplantation had greater risk of neutropenia and/or leukopenia,which were associated with higher clinical event rates and HCRU up to 5 years post-transplantation.These findings suggest the need for alternative prophylaxis options with lower myelosup-pressive effects to improve patient outcomes.
