Although analysis of registry data is useful, the effectiveness of interventions to reduce risk cannot be predicted with confidence from such analyses, and will require prospective intervention studies. See also article by Schold et al in this issue on page 550. [source]

Baseline Donor-Specific Antibody Levels and Outcomes in Positive Crossmatch Kidney Transplantation

AMERICAN JOURNAL OF TRANSPLANTATION, Issue 3 2010
J. M. Gloor
Renal transplant candidates with donor-specific alloantibody (DSA) have increased risk of antibody-mediated allograft injury. The goal of this study was to correlate the risk of antibody-mediated rejection (AMR), transplant glomerulopathy (TG) and graft survival with the baseline DSA level (prior to initiation of pretransplant conditioning). These analyses include 119 positive crossmatch (+XM) compared to 70 negative crossmatch (,XM) transplants performed between April 2000 and July 2007. Using a combination of cell-based crossmatch tests, DSA level was stratified into very high +XM, high +XM, low +XM and ,XM groups. In +XM transplants, increasing DSA level was associated with increased risk for AMR (HR = 1.76 [1.51, 2.07], p = 0.0001) but not TG (p = 0.18). We found an increased risk for both early and late allograft loss associated with very high DSA (HR = 7.71 [2.95, 20.1], p = 0.0001). Although lower DSA recipients commonly developed AMR and TG, allograft survival was similar to that of ,XM patients (p = 0.31). We conclude that the baseline DSA level correlates with risk of early and late alloantibody-mediated allograft injury. With current protocols, very high baseline DSA patients have high rates of AMR and poor long-term allograft survival highlighting the need for improved therapy for these candidates. [source]


Perceived barriers to adherence among adolescent renal transplant candidates

PEDIATRIC TRANSPLANTATION, Issue 3 2008
Nataliya Zelikovsky
Abstract:, Non-adherence to medical regimens is a ubiquitous hindrance to quality health care among adolescent transplant recipients. Identification of potentially modifiable barriers to adherence when patients are listed for organ transplant would help with early intervention efforts to prepare adolescents for the stringent medication regimen post-transplant. Fifty-six adolescents listed for a kidney transplant, mean age 14.27 (s.d. = 2.2; range 11,18 yr), 73.2% male, 62.5% Caucasian participated in a semi-structured interview, the Medical Adherence Measure, to assesses the patient's knowledge of the prescribed regimen, reported adherence (missed and late doses), the system used to organized medications, and who holds the primary responsibility over medication management. Better knowledge of the medication regimen was associated with fewer missed doses (r = ,0.48, p < 0.001). Patients who perceived more barriers had more missed (r = 0.38, p = 0.004) and late (r = 0.47, p < 0.001) doses. Patients who endorsed "just forget," the most common barrier (56.4%), reported significantly more missed (z = ,4.25, p < 0.001) and late (z = ,2.2, p = 0.02) doses. Only one-third of the transplant candidates used a pillbox to organize medications but these patients had significantly better adherence, z = ,2.2, p = 0.03. With regard to responsibility over managing the regimens, adolescents missed fewer doses when their parents were in charge than when they were solely responsible, z = ,2.1, p = 0.04. Interventions developed to prepare transplant candidates for a stringent post-transplant regimen need to focus on ensuring accurate knowledge of as simple a regimen as possible. Use of an organized system such as a pillbox to establish a routine and facilitate tracking of medications is recommended with integration of reminders that may be appealing for this age group. Although individuation is developmentally normative at this age, parent involvement seems critical until the adolescent is able to manage the responsibility more independently. [source]

Assessment of cardiovascular risk in waiting-listed renal transplant patients: a single center experience in 558 cases

CLINICAL TRANSPLANTATION, Issue 5 2009
G. Leonardi
Abstract:, Cardiac screening is recommended to prevent cardiovascular death after renal transplantation. This retrospective observational study illustrates the results of application of a cardiac assessment algorithm in a series of 558 renal transplant candidates at a single center in Turin, Italy. A dipyridamole-stress sestamibi myocardial scintiscan (DMS) performed in 302/558 (54.1%) cases was positive in 52 (17.2%), negative in 200 (66.2%), borderline in 16 (5.3%), and with signs of previous necrosis in 34 (11.4%). Coronary lesions detected by angiography in 48.1% of the 52 positives were treated medically (13.5%) or by percutaneous/surgical procedure (34.6%). Coronary lesions were detected in 14.1% of asymptomatic population subgroup. The minor and major cardiovascular event rates and the cardiovascular death rate were 1.9%, 0%, and 0%, respectively, in positive DMS group (high-cardiological risk) vs. 10%, 4.5%, and 3.5% in the negatives (p > 0.5; n.s.). It is suggested that not increased cardiovascular event or deaths rates in the high-risk group reflect early coronary lesion detection and correction. Since 55.9% of cardiovascular events or deaths occurred in the negative group more than 24 months after the DMS, its mandatory repetition every two yr after a negative finding is recommended.

Kidney graft survival in patients with hepatitis C: a single center experience

CLINICAL TRANSPLANTATION, Issue 1 2008
J Arango
Abstract:, Hepatitis C virus (HCV) infection is highly prevalent in renal transplant candidates; however, its effect on the transplant outcome is still controversial. The aim of the present study was to determine the effect of HCV infection in the outcome of kidney transplantation in a single transplant center. The study population 144 HCV, randomized selected patients and 64 HCV+ patients transplanted from 1973 to 2000, followed for up to 60 months post-transplantation. This retrospective study included the following variables: type of dialysis, time on renal replacement therapy, number of transfusions before and after transplantation, number of transplants, type of donor, immunosuppression, and rejection episodes. The Kaplan,Meier method was used to estimate graft and patient survival. Log-rank test was used to assess the difference in survival between HCV+ and HCV,. A multivariate Cox proportional hazards model was used to analyze the relation between graft and patient survival. HCV+ and HCV, patients had similar demographic and clinical characteristics; however, a higher number of HCV+ patients received blood transfusions after transplantation. Patient survival was not significantly different in 39 HCV+ and 96 HCV, patients transplanted with living-related donors (71% and 77% at five yr, respectively). Similarly, there was not significant difference in 25 HCV+ and 48 HCV, patients transplanted with kidneys from deceased donors, although there was a tendency to better outcome in HCV, patients (55% and 72% at five yr respectively). Regarding graft survival, there was also no differences in HCV+ and HCV, recipients of living-related grafts (61% and 66% at five yr post-transplant, respectively) and recipients of kidneys from deceases donors (44% and 41%, respectively). The results show that HCV+ patients can be transplanted with the same success than HCV, patients. [source]
