Abstract Background The incidence of cytomegalovirus (CMV) infection in solid organ transplant recipients may be reduced by antiviral prophylaxis, but this strategy may lead to delayed-onset CMV infection. The proinflammatory cytokine interleukin (IL)-18 plays a major role in viral host defense responses. This study examines the impacts of 2 single-nucleotide polymorphisms (SNPs) in the promoter region of the IL-18 gene, -607C/A (rs1946518) and -137G/C (rs187238), on the incidence of delayed-onset CMV infection in patients undergoing kidney transplant. Methods This retrospective study analyzed 2 IL-18 SNPs in consecutive adult kidney transplant recipients using real-time polymerase chain reaction with TaqMan probes. Participants were enrolled over the period 2005–2013 and stratified according to their IL-18 SNP genotype. The concordance index (Harrell’s c-index) was used as a measure of the discriminatory power of the predictive models constructed with bootstrapping to correct for optimistic bias. Results Seven hundred nine patients received transplants in the study period, and 498 met selection criteria. Cytomegalovirus infection and disease incidence were 38% and 7.5%, respectively. In multivariate competing risk regression models, carriers of the -607C/-137G haplotype who received prophylaxis showed a higher incidence of CMV replication after antiviral agent discontinuation (hazard ratio = 2.42 [95% confidence interval, 1.11–5.26]; P = .026), whereas CMV disease was not observed in those given prophylaxis who were noncarriers of this polymorphism (P = .009). Conclusions Our findings suggest that the -607C/-137G IL-18 haplotype is associated with a higher incidence of postprophylaxis CMV replication. The prior identification of this polymorphism could help select alternative measures to prevent delayed-onset CMV infection in these patients.

Background: Moderate-risk for Cytomegalovirus (CMV) infection includes patients with donor positive/recipient positive (D+/R+) or donor negative/ recipient positive antibody status (D-/R+). Guidelines recommend high-dose daily Valganciclovir (VGCV) as prophylaxis, which may be due to the paucity of data on the efficacy of every-other-day VGCV. Methods: Our experience of using every-other-day VGCV as a prophylactic strategy in moderate risk Kidney Transplant Recipients (KTR) has been described. We retrospectively reviewed 86 moderate-risk KTR in our institution between 2018 and 2020. CMV infection at 6 months post-transplant was the primary endpoint. Graft survival, biopsy-proven rejection, opportunistic infections, Haematological adverse events, and mortality were also evaluated. Results: CMV infection occurrence at 6 months was zero in our cohort. Incidence of leukopenia was 13%, BPAR-31%, OI-33%, and mortality being 3.5%. Conclusion: Every-Other-Day VGCV dosing can be an effective alternative in moderate risk KTR for CMV prevention.
