In this study, we aimed to assess the incidence of CMV DNAemia and its risk factors in Moroccan transplant recipients.Patients and Methods: Sixty kidney recipients with positive cytomegalovirus serostatus, receiving post-transplant prophylaxis were enrolled between 2013 and 2017. In total, 455 plasma samples were collected and tested for CMV DNAemia using PCR-based Abbott RealTime assays.Results: The incidence of CMV infection in seropositive patients was 63%. In patients with quantifiable DNAemia, the duration of CMV infection was significantly shorter than in those with detectable DNAemia (141.5 ± 96.9 vs 294.1 ± 112.6 days, P < 0.001). During prophylactic treatment, 14 of 30 patients (47.0%) experienced active replication with quantifiable DNAemia, whereas none of eight patients with detectable DNAemia did (P = 0.017). Patients with symptomatic DNAemia were significantly younger than those without symptoms (28.8 ± 5.12 vs 38.1 ± 12.34 years, P = 0.007). The peak viral loads were significantly associated with viral disease (odds ratio: 3.39, 95% confidence interval: 1.21– 9.53, P = 0.02). The duration of DNAemia (21.2 vs 13.4 days, P = 0.028) was significantly longer in symptomatic patients. Significantly higher rates of acute rejection were exclusively observed in recipients with disease (4/8, 50% vs 0/22, 0%, P = 0.003).Conclusion: Patients with high-level DNAemia were at an increased risk of progression to disease and acute rejection. Monitoring the viral load during the first year post-transplantation is essential, to support current preventive strategies.Keywords: cytomegalovirus, DNAemia, kidney transplant, disease, acute rejectionRezzouk BBouattar TBelkadi BRazine RBayahia ROuzeddoun NBenamar LRhou HBouihat NIbrahimi ASeffar MKabbaj HDove Medical Pressarticlecytomegalovirusdnaemiakidney transplantdiseaseacute rejection.Medicine (General)R5-920ENTransplant Research and Risk Management, Vol Volume 13, Pp 1-13 (2021) |
