The Impact

Background: Knowledge about the impact of allogeneic hematopoietic stem cell transplantation (alloHSCT) on renal function in children is still limited. Objectives: The aim of the study was to evaluate kidney function in children undergoing alloHSCT, with special focus on differences between patients transplanted due to oncological and non-oncological indications. Materials and Methods: The data of 135 children undergoing alloHSCT were analyzed retrospectively. The serum creatinine and estimated glomerular filtration rate (eGFR) values were estimated before transplantation at 24 h; 1, 2, 3, 4 and 8 weeks; and 3 and 6 months after alloHSCT. Then, acute kidney injury (AKI) incidence was assessed. Results: Oncological children presented with higher eGFR values and more frequent hyperfiltration rates than non-oncological children before alloHSCT and until the 4th week after transplantation. The eGFR levels rose significantly after alloHSCT, returned to pre-transplant records after 2–3 weeks, and decreased gradually until the 6th month. AKI incidence was comparable in oncological and non-oncological patients. Conclusions: Children undergoing alloHSCT due to oncological and non-oncological reasons demonstrate the same risk of AKI, but oncological patients may be more prone to sustained renal injury. Serum creatinine and eGFR seem to be insufficient tools to assess kidney function in the early post-alloHSCT period, when hyperfiltration prevails, yet they reveal significant differences in long-term observation.

The Impact

AbstractIn the current era of effective prophylactic and preemptive therapy, cytomegalovirus (CMV) is now a rare cause of early mortality after hematopoietic stem cell transplantation (HSCT). However, the ultimate goal of completely eliminating the impact of CMV on survival remains elusive. Although the direct effects of CMV (ie, CMV pneumonia) have been largely eliminated, several recent cohort studies show that CMV-seropositive transplant recipients and seronegative recipients of a positive graft appear to have a persistent mortality disadvantage when compared with seronegative recipients with a seronegative donor. Recipients of T-cell–depleted allografts and/or transplants from unrelated or HLA-mismatched donors seem to be predominantly affected. Reasons likely include both incomplete prevention of direct and indirect or immunomodulatory effects of CMV as well as consequences of drug toxicities. The effect of donor CMV serostatus on outcome remains controversial. Large multicenter cohort studies are needed to better define the subgroups of seropositive patients that may benefit from intensified prevention strategies and to define the impact of CMV donor serostatus in the era of high-resolution HLA matching. Prevention strategies may require targeting both the direct and indirect effects of CMV infection by immunologic or antiviral drug strategies.

Abstract Abstract 3517 Allogeneic hematopoietic stem cell transplantation with reduced intensity conditioning (RIC-HSCT) is increasingly applied for the treatment of patients with acute myeloid leukemia. However, the procedure is heterogeneous with no standards based on randomized trials being elaborated so far. Hence, particular therapeutic decisions are in major part based on individual experience. The goal of this study was to evaluate the impact of center experience on outcome of RIC-HSCT. Based on the registry of ALWP of the EBMT, we analyzed results of 1413 HLA-matched related (n=1058) or unrelated (n=355) transplantations performed in 203 European centers between 2001 and 2007. Only patients with AML in first complete remission were included. Median recipient age was 55 years (range, 18–77 y.). Centers were categorized by quintiles according to the number of RIC-HSCT procedures in a study period. The 2 years probability of leukemia-free survival (LFS) after RIC-HSCT performed in centers with the lowest activity (1st quintile, ≤ 15 procedures/7 years) equaled 43% compared to 55% in the remaining ones (p<0.001). The incidence of non-relapse mortality (NRM) was 24% and 15%, respectively (p=0.004). In a multivariate model adjusted for other potential prognostic factors low RIC-HSCT activity was associated with decreased chance of LFS (HR=0.69, p<0.001) as well as increased risk of NRM (HR=1.69, p=0.001) and relapse (HR=1.37, p=0.01). No significant differences were found between centers belonging to the 2nd -5th quintile. We conclude that center experience is a strong predictor of outcome and should be considered for future analyses evaluating results of RIC-HSCT.
