The impact of viral load and time to onset of cytomegalovirus replication on long-term graft survival after kidney transplantation

Original language description

Background: Asymptomatic cytomegalovirus (CMV) infection is associated with graft dysfunction and failure. However, no study assessed CMV viral load in terms of the risk for graft failure. Methods: In prospective cohort of kidney transplant recipients, we assessed the impact of CMV DNAemia on the overall graft survival and the incidence of moderate-to-severe interstitial fibrosis and tubular atrophy (IF/TA) in protocol biopsy at 36 months. CMV DNAemia was stratified by viral load in whole blood. Results: A total of 180 patients transplanted from October 2003 through January 2011 were included and followed for 4 years; 87 (48%) patients received 3-month prophylaxis with valacyclovir and 45 (25%) with valganciclovir; 48 (27%) were managed by preemptive therapy. Within 12 months of transplantation, CMV DNAemia developed in 102 (57%) patients with 36 (20%) having a viral load of GREATER-THAN OR EQUAL TO2000 copies/ml. Multivariate Cox analysis identified CMV DNAemia as an independent risk factor for graft loss (hazard ratio 3.42, P=0.020); however, after stratification by viral load, only CMV DNAemia GREATER-THAN OR EQUAL TO2000 copies/ml (hazard ratio 7.62, P&lt;0.001) remained significant. Both early-onset (&lt;3 months, P=0.048) and late-onset (&gt;3 months, P&lt;0.001) CMV DNAemia GREATER-THAN OR EQUAL TO2000 copies/ml were risk factors for graft loss. The incidence of moderate-to-severe IF/TA was not significantly influenced by CMV DNAemia. Conclusions: Kidney transplant recipients having CMV DNAemia with a higher viral load irrespective of the time to onset are at increased risk for graft loss.
