Abstract: Background: Cytomegalovirus (CMV) presents a serious threat to CMV‐seronegative recipients (R−), who have received an organ from a seropositive donor (D+).Objectives: We compared the effectiveness of three different prophylactic protocols in CMV D+/R− patients and reviewed data on patients who received no prophylaxis.Patients and methods: We reviewed 1137 kidney transplantations from 1995 to 2004. Of these, 147 recipients were CMV negative (D+/R−); 125 patients received CMV prophylaxis. Group I received CMV hyperimmune gammaglobulin only, group II received CMV hyperimmune gammaglobulin plus oral ganciclovir, and group III received prophylaxis with oral ganciclovir only.Results: In group I, CMV infection was observed in 31 of 53 patients (59%), and CMV disease was diagnosed in 9 (17%) during the prophylaxis. In the first year post transplant, a total of 41 of 53 patients (77.5%) had primary CMV infection. In group II, CMV infection occurred in 7 of 30 patients (23%), and CMV disease was diagnosed in only 2 (7%) during prophylaxis. In the first year post transplant, a total of 9 of 30 patients (30%) had primary CMV infection. In group III, 9 of 42 patients (21%) developed CMV infection during prophylaxis, and CMV disease was not observed. In the first year post transplant, a total of 13 of 42 patients (30%) had primary CMV infection. In contrast, all 22 CMV D+/R− patients without prophylaxis developed CMV infection (100%); CMV disease was diagnosed in 10 (45%), and 1 patient died.Conclusions: Prophylaxis with hyperimmune gammaglobulin and/or oral ganciclovir significantly reduces CMV infection and disease. Prophylaxis with ganciclovir was significantly more effective than hyperimmune gammaglobulin monoprophylaxis, and more cost effective than combined prophylaxis.
