Introduction: Human Cytomegalovirus (CMV) infection is still a major risk factor for immunocompromised patients, e.g. kidney recipients. Based on the CMV serostatus of donor (D) and recipient (R) several risk groups are defined: low (D-/R-), intermediate (D+/R+ or D-/R+), high risk (D+/R-) patients. In a preliminary study (Schlott et al 2016), cold ischemia time (CIT) was shown to be associated with primary CMV infection in D+R- high risk patients.
Patients: At MHH, from a cohort of 131 kidney recipients, CMV D+/R- (n=21) high risk patients were analyzed for CMV infection/seroconversion, correlated with CIT and immunophenotyping was performed.
Results: CIT differed significantly between 10 living donors (median=145min) and 11 deceased donors (median=565min; p<0.0001). Patients without CMV infection (n=15) had significantly shorter CIT (median=177 min) compared to 6 patients with primary CMV infection and prolonged CIT (median=755min; p=0.001). Furthermore, none of the 10 recipients of living donor kidneys developed CMV infection/seroconversion while 6 of 11 recipients of deceased donor kidneys displayed CMV positivity after at least 6 months post Tx (p= 0.001).
Conclusion: Taken together, with two cohorts of kidney recipients at TUM and MHH, we could confirm that prolonged CIT is associated with an increased risk for primary CMV infection in D+/R- high risk recipients. This observation may have clinical relevance for the antiviral treatment of this high risk group, especially in deceased donor kidney transplantations with naturally prolonged CIT.
