In an effort to better understand the clinical impact of lymphocyte-depleting induction therapy, the aim of our retrospective association study was to evaluate patient demographics and outcome in light of postoperative lymphocyte depletion and recovery. CMV represents one of the major pathogens associated with patient survival and long-term graft function [26]. Although CMV status and recipient age are established risk factors in solid organ transplantation, we herein provide evidence that both CMV status and age have an impact on lymphocyte count in kidney transplantation. Macedo et al. investigated the long-term effect of alemtuzumab on T-memory and regulatory subsets after KTx. Findings from this trial indicate an association between effector memory T-cell predominance and increased alloimmune response late after lymphodepletion in KTx [27]. Apart from the retrospective nature of our study hampered by all limitations of this type of analysis, in this study, we have Ku 0059436 identified a significant relation between DGF occurrence and lymphocyte counts after administering the anti-CD52-antibody alemtuzumab. This correlation could not be detected in the basiliximab group, and hence this effect seems to be correlated with the type of induction treatment. At this point, it should be emphasized that deviations in the demographics of the two groups may have had an impact on the results and limit the conclusions drawn from this trial. Nevertheless, the induction treatment seems to have a major impact on DGF and CMV. Cytomegalovirus represents one of the most important single pathogens in solid organ transplantation and CMV-related complications in organ and composite tissue transplantation have been well documented. However, CMV has not been analyzed in the context of lymphocyte recovery and the occurrence of DGF after depleting therapy for KTx. Furthermore, our data revealed a relationship between age, female gender, and lymphocyte counts after induction therapy with alemtuzumab. Trzonkowski et al. investigated the homeostatic repopulation by CD28-CD8+ T-cells in alemtuzumab-depleted kidney transplantation recipients. The study demonstrated that CD28-CD8+ T-cells increase in proportion over CD4+ T-cells. This may contribute to a status of compromised immunity, which allows the minimization of maintenance immunosuppressive therapy after alemtuzumab induction [28]. Immunosuppressive protocols with early introduction of an mTor-inhibitor in a calcineurin inhibitor sparing protocol after alemtuzumab induction resulted in an increase in T-reg cells [29]. Hester et al. assessed T-regulatory cells and Th1/Th17 responses in 10 kidney recipients, more than 4 years after alemtuzumab. Their data indicate that a history of rejection and long-term immunosuppressive therapy have an impact on the number of circulating T-regs and Th17 cells [30].
