Objectives: Valganciclovir 900 mg/day is approved for cytomegalovirus (CMV) prophylaxis, but 450 mg/day is seems also effective. We systematically reviewed the efficacy and safety of low-dose versus high-dose valganciclovir prophylaxis in renal transplantation recipients. Methods: An electronic search was conducted up to November 29, 2016. The primary outcomes were incidences of CMV, CMV disease, mortality and opportunistic infection. The second outcomes were acute rejection, allograft loss, adverse drug reaction (ADR). Results: 7 cohort studies, all with high quality involving (1431 patients) were included. There was no significant difference of the incidence of following CMV disease (1271 patients, odds ratio [OR] 0.74, 95% confidence interval [CI], 0.38-1.43, p=0.36), acute rejection (1343 patients, OR 0.77, 95%CI 0.53-1.14, p=0.19), allograft loss (1271 patients, OR 0.64, 95%CI 0.31-1.35, p=0.24), mortality (1271 patients, OR 0.55, 95%CI 0.20-1.47, p=0.23) and opportunistic infections (OI) (985 patients, OR 0.76, 95%CI 0.52-1.10, p=0.14) between the low-dose and the high-dose valganciclovir  prophylaxis. And no significant difference was observed for premature valganciclovir discontinuation (1010 patients, OR 0.81, 95%CI 0.52-1.25, p=0.33) and the incidence of leukopenia (1082 patients, OR 0.65, 95%CI 0.34-1.22, p=0.18) between the two regimens. Conclusion: 450 mg and 900 mg doses of valganciclovir are equipotent for CMV universal prophylaxis. CMV 450 mg prophylaxis should be used for renal transplant recipients.
