This overview summarizes recent data on emerging viruses after hematopoietic cell transplantation (HCT), including adenovirus, BK virus, human metapneumovirus (hMPV), and human herpesvirus (HHV) 6. The increased recognition of these infections is due to improved molecular detection methods, increased surveillance and more profound immunosuppression in the host. Adenovirus can cause serious disease especially in T-cell depleted transplant recipients. Adenovirus viremia is an important risk factor for disease in this setting. BK virus has been associated with hemorrhagic cystitis in HCT recipients. BK viremia is significantly associated with hemorrhagic cystitis. hMPV shows a seasonal distribution and can cause fatal pneumonia in HCT recipients. hMPV may be the etiology of some cases previously categorized as idiopathic pneumonia syndrome. HHV-6 commonly leads to viremia in HCT recipients. HHV-6 has been strongly associated with encephalitis and delayed platelet engraftment. Prospective studies are needed to further examine epidemiology, disease associations, and management strategies for these viruses.

Background: The possible additional risk of infection in patients receiving induction with both basiliximab (Ba) and thymoglobulin (Th) is unclear. We assessed the 1-year incidence of infectious complications in 3 groups of kidney transplant recipients according to the type of induction therapy received.Methods: We compared the incidence of infection at 1 year in 3 groups of patients at our institution: fi rst transplant recipients received Ba 20mg at days 0 and 4 (Group Ba); in case of retransplantation or if PRA was >20% patients received Th 1 mg/kg for 3-5 days (Group Th); in case of delayed graft function (DGF), Ba was discontinued and Th was initiated (Group Ba+Th) or prolonged in Group Th. Kaplan-Meier curves were used to calculate the incidence of infection. A Cox analysis was used to identify risk factors for the development of infection.Results: Over 5 years, 170 consecutive kidney transplant recipients were performed:n=113 in Group Ba, n=39 in Group Th and n=18 in Group Ba+Th. As expected, more patients in Group Th received a second transplant (p<0.001). No differences in CMV serostatus were observed between groups (p=0.9). Incidences of CMV infection, CMV disease, BK viremia, BK nephropathy and urinary tract infection (UTI) is shown in Table 1. Table 1 Group Ba (n=113) Group Th (n=38) Group Ba+Th (n=18) CMV infection 31 (27%) 20 (51%) 8 (44%) CMV disease 7 (6%) 4 (10%) 0 BK viremia 11 (8%) 5 (13%) 4 (22%) BK nephropathy 5 (4%) 1 (2%) 2 (11%) UTI 43 (38%) 23 (59%) 6 (33%) Incidences of infection according to type of induction In a multivariate model taking into account CMV serostatus, age, pretransplant dialysis, type of organ transplanted, number of transplants and type of induction, Group Ba carried a lower risk of CMV infection (OR 0.45, p=0.006), and UTI (OR=0.6, p=0.05), but there were no differences in CMV disease (p=0.38). There was a trend towards higher incidence of BK viremia, but not nephropathy in Group Ba+Th (OR 2.2, p=0.23). There were no signifi cant differences in kidney function or graft loss at 1 year between groups.Conclusion: By multivariate analysis, we observed a lower risk of CMV infection andUTI in patients receiving Ba. The group Ba+Th had a similar risk for infection than the group receiving Th alone. Larger studies are needed to clarify whether combining Ba+Th in the setting of DGF may increase the risk of infectious complications, in particular BK infection.

With the advent of more potent immunosuppressive regimens, the incidence of acute rejection following renal transplantation has declined sharply in recent years. In spite of this, long-term graft outcomes remain suboptimal because of relentless attrition by cumulated insults to the allograft. As acute rejection rates have declined, other causes of graft injury and loss have recently emerged. Among these, infectious diseases remain a persistent threat and can be associated with allograft dysfunction. This group includes nephropathy due to polyoma (BK) virus infection, cytomegalovirus disease, and bacterial infection (the latter most commonly arising from the urinary tract). Rarer infectious causes of chronic allograft dysfunction include cryoglobulinemia associated with hepatitis C, Epstein-Barr virus-associated posttransplant lymphoproliferative disease, and direct cytotoxicity from adenoviral infection or parvovirus B19.
