- Prophylactic Anti-Virus Therapy, Is It Necessary to Occult Hepatitis B Virus Carriers with HBsAg(-) and HBcAb(+) After Kidney Transplantation?
- BK Virus (BKV) Infection in Renal Transplantation: Excellent Outcomes with a Protocol of Intensive Post-Transplant Screening with Reduction in Immunosuppression & Treatment with Leflunomide and/or Low Dose Cidofovir
Purpose: There is still an ongoing discussion whether a prophylactic or a preemptive therapy against cytomegalovirus (CMV) is superior to reduce the incidence of CMV viremia, acute rejections (AR) or cardiac allograft vasculopathy (CAV) after heart transplantation (HTx). Thus, we evaluated different CMV treatment strategies in this setting.
Methods: HTx patients (n=56) were retrospectively studied from 01/01/2010 to 01/31/2016. Study end points were the CMV-free survival viremia, AR, and CAV. The average follow-up was 4.15 years (355 days up to 7.5 years). Patients were classified into 3 groups according to their received CMV therapy: preemptive therapy (n=19), prophylactic drug monotherapy (either valganciclovir for 3 months or early single dose of 1mg/kg/BW of CMV immunoglobulin, CMVIG, 2 weeks post-HTx, n=18) or prophylactic double drug therapy (valganciclovir for 3 months plus early single dose of CMVIG, n=19). For statistical analysis X2, X2-log-rank and T-Tests were used.
Results: The median patient survival was not significant different among the study groups: preemptive group 2243 days, prophylactic monotherapy 2417 days, and prophylactic double therapy 2410 days, respectively. However, the median CMV-viremia free survival was different among the groups: 1817 days in the prophylactic double group, 1459 days in the prophylactic mono group and 1482 in the preemptive group (p=0.52). A subanalysis of patients with high risk for CMV infection (donor positive and recipient negative CMV status) the CMV-free survival was significantly higher when patients received double prophylaxis therapy compared to the other two groups (p<0.01). Whether the incidence of AR nor of CAV was not significantly influenced by the choice of CMV treatment regimen. The antiviral medication was discontinuated in 10.5% preemptive group, 38.9% prophylactic mono group, and 31.6% prophylactic double group, respectively.
Conclusion: Our study results suggest that early therapy with CMVIG as adjunct to antiviral treatment could prolong CMV-free survival in patients with CMV risk of infection. If a repetitive CMVIG dosing post-HTx will further reduce CMV infection needs to be explored in the future.
