Waitlist and Transplant Outcomes in Organ Donation After Circulatory Death: Trends in the United States.

OBJECTIVES: To summarize waitlist and transplant outcomes in kidney, liver, lung, and heart transplantation using organ donation after circulatory death (DCD). BACKGROUND: DCD has expanded the donor pool for solid organ transplantation, most recently for heart transplantation. METHODS: The United Network for Organ Sharing registry was used to identify adult transplant candidates and recipients in the most recent allocation policy eras for kidney, liver, lung, and heart transplantation. Transplant candidates and recipients were grouped by acceptance criteria for DCD versus brain-dead donors [donation after brain death (DBD)] only and DCD versus DBD transplant, respectively. Propensity matching and competing-risks regression was used to model waitlist outcomes. Survival was modeled using propensity matching and Kaplan-Meier and Cox regression analysis. RESULTS: DCD transplant volumes have increased significantly across all organs. Liver candidates listed for DCD organs were more likely to undergo transplantation compared with propensity-matched candidates listed for DBD only, and heart and liver transplant candidates listed for DCD were less likely to experience death or clinical deterioration requiring waitlist inactivation. Propensity-matched DCD recipients demonstrated an increased mortality risk up to 5 years after liver and kidney transplantation and up to 3 years after lung transplantation compared with DBD. There was no difference in 1-year mortality between DCD and DBD heart transplantation. CONCLUSIONS: DCD continues to expand access to transplantation and improves waitlist outcomes for liver and heart transplant candidates. Despite an increased risk for mortality with DCD kidney, liver, and lung transplantation, survival with DCD transplant remains acceptable.

Apolipoprotein L1 Opinions of African American Living Kidney Donors, Kidney Transplant Patients, and Nonpatients.

INTRODUCTION: The discovery of apolipoprotein L1 (ApoL1) has raised important ethical and clinical questions about genetic testing in the context of living and deceased kidney donation. Largely missing from this discussion are the perspectives of those African Americans (AA) most likely to be impacted by ApoL1 testing. METHODS: We surveyed 331 AA potential and former living kidney donors (LKDs), kidney transplant candidates and recipients, and nonpatients at three United States transplant programs about their ApoL1 testing attitudes. RESULTS: Overall, 72% felt that transplant programs should offer ApoL1 testing to AA potential LKDs. If a potential LKD has the high-risk genotype, 79% felt that the LKD should be allowed to make their own donation decision or participate in shared decision-making with transplant doctors. More than half of the potential LKDs (58%) would undergo ApoL1 testing and 81% of former LKDs would take the test now if offered. Most transplant candidates expressed a low likelihood of accepting a kidney from a LKD (79%) or a deceased donor (67%) with the high-risk genotype. CONCLUSIONS: There is strong support among LKDs and transplant patients for ApoL1 testing when evaluating potential kidney donors of African ancestry. Inclusion of AA stakeholders in developing guidelines and educational programs for ApoL1 testing is critical.

National trends and outcomes of heart-kidney transplantation using hepatitis C positive donors.

BACKGROUND: This study evaluated the outcomes of combined heart-kidney transplantation in the United States using hepatitis C positive (HCV+) donors. METHODS: Adults undergoing combined heart-kidney transplantation from 2015 to 2020 were identified in the United Network for Organ Sharing registry. Patients were stratified by donor HCV status. Kaplan-Meier curves with multivariable Cox regression models were used for risk-adjustment in a propensity-matched cohort. RESULTS: A total of 950 patients underwent heart-kidney transplantation of which 7.8% (n = 75) used HCV+ donors; 68% (n = 51) were viremic and 32% (n = 24) were non-viremic donors. Unadjusted 1-year recipient survival was similar between HCV+ versus HCV- donors (84% vs 88%, respectively; P = .33). Risk-adjusted analysis in the propensity-matched cohort showed HCV+ donor use did not confer increased risk of 1-year mortality (hazard ratio .63, 95% CI .17-2.32; P = .49). Sub-group analysis showed viremic and non-viremic HCV+ donors had similar 1-year survival as well (84% vs 84%; P = .95). CONCLUSIONS: Compared with recipients of HCV- donor dual heart-kidney transplants, recipients of HCV+ organs had comparable 1-year survival and clinical outcomes after combined transplantation. Although future studies should evaluate other outcomes related to HCV+ donor use, this practice appears safe and should be expanded further in the heart-kidney transplant population.

Opinions of African American adults about the use of apolipoprotein L1 (ApoL1) genetic testing in living kidney donation and transplantation.

Apolipoprotein L1 (ApoL1) predictive genetic testing for kidney disease, and its emerging role in transplantation, remains controversial as it may exacerbate underlying disparities among African Americans (AAs) at increased risk. We conducted an online simulation among AAs (N = 585) about interest in ApoL1 testing and its cofactors, under 2 scenarios: as a potential living donor (PLD), and as a patient awaiting transplantation. Most respondents (61%) expressed high interest in genetic testing as a PLD: age ≥35 years (adjusted odds ratio [aOR], 1.75; 95% confidence interval [CI], 1.18, 2.60, P = .01), AA identity (aOR, 1.67; 95% CI, 1.02, 2.72, P = .04), perceived kidney disease risk following donation (aOR, 1.68; 95% CI, 1.03, 2.73, P = .03), interest in genetics (aOR, 2.89; 95% CI, 1.95, 4.29, P = .001), and genetics self-efficacy (aOR, 2.38; 95% CI, 1.54, 3.67, P = .001) were positively associated with ApoL1 test interest. If awaiting transplantation, most (89%) believed that ApoL1 testing should be done on AA deceased donors, and older age (aOR, 1.85; 95% CI, 1.03, 3.32, P = .04) and greater interest in genetics (aOR, 2.61; 95% CI, 1.41, 4.81, P = .002) were associated with interest in testing deceased donors. Findings highlight strong support for ApoL1 testing in AAs and the need to examine such opinions among PLDs and transplant patients to enhance patient education efforts.

A distance-based living donor kidney education program for Black wait-list candidates: A feasibility randomized trial.

Addressing racial disparities in living donor kidney transplants (LDKT) among Black patients warrants innovative programs to improve living donation rates. The Living Organ Video Educated Donors (LOVED) program is a 2-arm, culturally-tailored, distance-based, randomized controlled feasibility trial. The group-based, 8-week program used peer-navigator led video chat sessions and web-app video education for Black kidney waitlisted patients from United States southeastern state. Primary feasibility results for LOVED (n = 24) and usual care (n = 24) arms included LOVED program tolerability (i.e., 95.8% retention), program fidelity (i.e., 78.9% video education adherence and 72.1% video chat adherence). LDKT attitudinal and knowledge results favored the LOVED group where a statistically significant effect was reported over 6-months for willingness to approach strangers (estimate ± SE: -1.0 ± .55, F(1, 45.3) = 7.5, P = .009) and self-efficacy to advocate for a LDKT -.81 ± .31, F(1, 45.9) = 15.2, P < .001. Estimates were improved but not statistically significant for willingness to approach family and friends, LDKT knowledge and concerns for living donors (all P's > .088). Secondary measures at 6 months showed an increase in calls for LOVED compared to usual care (P = .008) though no differences were found for transplant center evaluations or LDKTs. Findings imply that LOVED increased screening calls and attitudes to approach potential donors but feasibility outcomes found program materials require modification to increase adherence.

Impact of a multidisciplinary multimodal opioid minimization initiative in kidney transplant recipients.

Opioid use after kidney transplant has been shown to be a risk factor for chronic opioid use, which leads to an increased risk of mortality. The purpose of this study was to evaluate the early impact of a multimodal pain regimen and education quality improvement program on opioid use after kidney transplant 2 months after implementation. This was a retrospective, single-center analysis of post-operative opioid use, comparing the average daily Morphine milligram equivalents (MME) of the patients who received education on opioids and a multimodal pain regimen (preoperative TAP/QL block, scheduled APAP and gabapentin) compared to a historical control group. Despite having no differences in pre-transplant opioid exposure, daily and overall inpatient opioid utilization was significantly reduced in the multimodal pain protocol cohort (38.6 vs 8.0 MME/day; P < .001); 5% of patients in the multimodal pain protocol cohort were discharged with an opioid prescription, compared to 96% of controls (P < .001). Our early results demonstrate that a multimodal pain protocol can effectively and dramatically reduce short-term opioid utilization in kidney transplant recipients.

Long-standing diabetes mellitus and pancreas transplantation: An avenue to increase utilization of an ideal treatment modality.

BACKGROUND: Diabetes mellitus (DM) is associated with increased post-operative complications in various surgeries. Little data exist regarding the impact of long-standing DM (>25 years) on outcomes in pancreas transplantation (PTX). The objectives of our study were to determine if long-standing pre-transplant DM (>25 years) was associated with inferior outcomes following PTX. METHODS: Using a 13-year (April, 2000-May, 2012) retrospective analysis, we examined demographic and transplant factors, complications, and outcomes in patients without (Group A) and with (Group B) long-standing (>25 years) pre-PTX DM. RESULTS: Mean follow-up was 4.2 years. Of 214 consecutive PTX performed, 137 (105 simultaneous PTX (SPK), 25 PTX after kidney (PAK), 7 PTX alone (PTA)) had pre-PTX duration of DM recorded, including 65 in Group A and 72 in Group B. There were no differences between cohorts with respect to demographics. There were no differences in post-PTX surgical/medical complications. There were no differences in outcomes between cohorts (ie, rejection, graft loss or death). CONCLUSIONS: This large-scale analysis demonstrated that PTX can be performed in patients with long-standing DM with excellent patient and graft outcomes. Long-standing DM did not lead to an increased post-PTX infections or complications. Our study suggests that duration of DM should not impact PTX candidacy.

Cytolytic Induction Therapy Improves Clinical Outcomes in African-American Kidney Transplant Recipients.

OBJECTIVE: Determine the impact of cytolytic versus IL-2 receptor antibody (IL-2RA) induction on acute rejection, graft loss and death in African-American (AA) kidney transplant (KTX) recipients. BACKGROUND: AAs are underrepresented in clinical trials in transplantation; thus, there is controversy regarding the optimal choice of perioperative antibody induction in KTX to improve outcomes. METHODS: National cohort study using US transplant registry data from January 1, 2000 to December 31, 2009 in adult solitary AA KTX recipients, with at least 5 years of follow-up. Multivariable logistic and Cox regression were utilized to assess the outcomes of acute rejection, graft loss, and mortality, with interaction terms to assess effect modification. RESULTS: Twenty-five thousand eighty-four adult AAs receiving solitary KTX were included, 16,927 (67.5%) received cytolytic induction and 8157 (32.5%) received IL-2RA induction. After adjustment for recipient sociodemographics, donor, and transplant characteristics, the use of cytolytic induction therapy reduced the risk of acute rejection by 32% (OR 0.68, 0.62-0.75), graft loss by 9% (HR 0.91, 0.86-0.97), and death by 12% (HR 0.88, 0.83-0.94). There were a number of significant effect modifiers, including public insurance, panel reactive antibody, delayed graft function, and steroid withdrawal; in these groups, cytolytic induction substantially improved clinical outcomes. CONCLUSIONS: These data demonstrate that cytolytic induction therapy, as compared with IL-2RA, reduces the risk of rejection, graft loss, and death in adult AA KTX recipients, particularly in those who are sensitized, receive public insurance, develop delayed graft function, or undergo steroid withdrawal.

The Impact of Health Care Appointment Non-Adherence on Graft Outcomes in Kidney Transplantation.

BACKGROUND: Non-adherence to medication is a well-studied and known cause of late allograft loss, but it is difficult to measure and prospectively monitor. The aim of this study was to assess if appointment non-adherence was correlated with medication non-adherence and a predictor of graft outcomes. METHODS: This was a longitudinal cohort study that used the National United States Renal Data System and veterans affairs health records data with time-to-event analyses conducted to assess the impact on graft and patient survival. RESULTS: The number of transplants that were included in the analysis was 4,646 (3,656 with complete records); 14.6% of patients had an appointment no show rate of ≥12% (non-adherence). Appointment and medication non-adherence were highly correlated and both were significant independent predictors of outcomes. Those with appointment non-adherence had 1.5 times the risk of acute rejection (22.0 vs. 14.7%, p < 0.0001) and a 65% higher risk of graft loss (adjusted hazards ratio (aHR) 1.65, 95% CI 1.38-1.97, p < 0.0001). There was a significant interaction between appointment and medication non-adherence; those with appointment and medication non-adherence were at very high risk of graft loss (aHR 4.18, 95% CI 3.39-5.15, p < 0.0001), compared to those with only appointment non-adherence (aHR 1.39, 95% CI 0.97-2.01, p = 0.0766) or only medication non-adherence (aHR 2.44, 95% CI 2.11-2.81, p < 0.0001). CONCLUSION: These results demonstrate that non-adherence to health care appointments is a significant and independent risk factor for graft loss.

Valganciclovir (VGCV) followed by cytomegalovirus (CMV) hyperimmune globulin compared to VGCV for 200 days in abdominal organ transplant recipients at high risk for CMV infection: A prospective, randomized pilot study.

BACKGROUND: With the advent of effective antivirals against cytomegalovirus (CMV), use of CMV hyperimmune globulin (HIG) has decreased. Although antiviral prophylaxis in patients at high risk for CMV is effective, many patients still have late infection, never developing antibodies sufficient to achieve immunity. Utilizing a combination of antiviral and CMV HIG may allow patients to achieve immunity and decrease late CMV infections. METHODS: This was a prospective randomized, open-label, pilot study comparing valganciclovir (VGCV) prophylaxis for 200 days vs VGCV for 100 days followed by CMV HIG in abdominal transplant recipients at high risk for CMV. The primary outcome was a comparison of late CMV disease. RESULTS: Forty patients were randomized to VGCV for 200 days (n = 20) or VGCV for 100 days followed by 3 doses of monthly CMV HIG (n = 20). Numerically, more overall CMV infections occurred in the CMV HIG group (45 vs 20%, P = .09). No differences in overall CMV infections or late CMV disease were seen between groups (20% vs 15%, P = 1.00 and 0 vs 0, P = 1.00). All CMV disease occurred within 200 days, with 63% occurring while patients were on VGCV. No differences were found in toxicities, graft function, or rejection between groups. Patients with CMV infection at any time had a higher body weight than those who did not have an infection (82 vs 95 kg, P = .049). CONCLUSION: Use of CMV HIG sequentially with prophylaxis may be an effective and affordable prophylactic regimen in abdominal transplant recipients at high risk for CMV, and warrants larger prospective study. Increased monitoring for patients with obesity may be warranted.

Twenty years of evolving trends in racial disparities for adult kidney transplant recipients.

Disparities in outcomes for African American (AA) kidney transplant recipients have persisted for 40 years without a comprehensive analysis of evolving trends in the risks associated with this disparity. Here we analyzed U.S. transplant registry data, which included adult Caucasian or AA solitary kidney recipients undergoing transplantation between 1990 and 2009 comprising 202,085 transplantations. During this 20-year period, the estimated rate of 5-year graft loss decreased from 27.6% to 12.8%. Notable trends in baseline characteristics that significantly differed by race over time included the following: increased prevalence of diabetes from 2001 to 2009 in AAs (5-year slope difference: 3.4%), longer time on the waiting list (76.5 more days per 5 years in AAs), fewer living donors in AAs from 2003 to 2009 (5-year slope difference: -3.36%), more circulatory death donors in AAs from 2000-09 (5-year slope difference: 1.78%), and a slower decline in delayed graft function in AAs (5-year slope difference: 0.85%). The absolute risk difference between AAs and Caucasians for 5-year graft loss significantly declined over time (-0.92% decrease per 5 years), whereas the relative risk difference actually significantly increased (3.4% increase per 5 years). These results provide a mixed picture of both promising and concerning trends in disparities for AA kidney transplant recipients. Thus, although the disparity for graft loss has significantly improved, equity is still far off, and other disparities, including living donation rates and delayed graft function rates, have widened during this time.

A patient navigator and education program for increasing potential living donors: a comparative observational study.

BACKGROUND AND OBJECTIVES: Person-centered clinical environments may promote living donation for patients with end-stage renal disease (ESRD). We implemented an observational study design to explore whether a patient navigator (PN) program with person-centered education in nephrology practice settings could increase potential living donors (PLDs) and, subsequently, increase living transplantation. DESIGN, SETTING, PARTICIPANTS, AND MEASURES: Patients referred to (N = 4621) and/or transplanted at (N = 950) our transplant center during 2007-2012 were eligible for inclusion. Two analytical study populations were derived from propensity score matched patient groups. Outcomes comprised total PLDs per candidate and living vs. deceased transplantation for recipients. RESULTS: Multivariable generalized estimating equations logistic regression showed that PN practice candidates were significantly more likely to have an initial inquiry PLD (odds ratio [OR] = 1.21, 95% confidence interval [CI] = 1.01-1.44) and a preliminary screening PLD (OR = 1.27, 95% CI = 1.05-1.54), while there were no significant differences observed in evaluated PLD (OR = 0.94, 95% CI = 0.61-1.45). CONCLUSIONS: Our results suggest that our person-centered PN program stimulated willingness to seek living transplantation and was associated with a trend toward increased LD.

A randomized, prospective comparison of transition to sirolimus-based CNI-minimization or withdrawal in African American kidney transplant recipients.

BACKGROUND: There is a lack of conclusive evidence to suggest if calcineurin inhibitor (CNI) withdrawal or minimization with sirolimus is the best strategy for African Americans. METHODS: This was a randomized, prospective, open-label, pilot study comparing the two mammalian target of rapamycin (mTOR) transition strategies in adult African Americans between six and 24 wk post-transplant. The primary outcome was a comparison of the eGFR at one yr after conversion. RESULTS: Forty patients were randomized and analyzed in an intent-to-treat fashion. Median day of transition was day 96 (withdrawal) and 68 (minimization). Patients in the CNI-withdrawal group (n = 23) had significantly higher eGFR at one yr compared to the CNI-minimization group (n = 17, 73 vs. 56 mL/min, p = 0.03), as well as a significantly larger increase in eGFR from baseline (12 vs. 5 mL/min, p = 0.03). There were no differences in infections, acute rejection, death, or graft loss. Both regimens were constrained by disproportionately high discontinuation rates despite modest toxicity profiles. CONCLUSION: In spite of considerable withdrawal rate across both study arms, African American kidney transplant recipients who underwent early transition to a sirolimus-based CNI-withdrawal regimen had significantly better graft function at one yr compared to those transitioned to a sirolimus-based CNI-minimization regimen. Clinicaltrials.gov identifier: NCT01005706.

Predicting and preventing readmissions in kidney transplant recipients.

A lack of research exploring post-transplant process optimization to reduce readmissions and increasing readmission rates at our center from 2009 to 2013 led to this study, aimed at assessing the effect of patient and process factors on 30-d readmission rates after kidney transplantation. This was a retrospective case-control study in adult kidney transplant recipients. Univariate and multivariate analyses were utilized to assess patient and process determinants of 30-d readmissions. 384 patients were included; 30-d readmissions were significantly associated with graft loss and death (p = 0.001). Diabetes (p = 0.049), pharmacist identification of poor understanding or adherence, and prolonged time on hemodialysis prior to transplant were associated with an increased risk of 30-d readmissions. After controlling for risk factors, readmission rates were only independently predicted by pharmacist identification of patient lack of understanding or adherence regarding post-transplant medications and dialysis exposure for more than three yr (OR 2.3, 95% CI 1.10-4.71, p = 0.026 and OR 2.1, 95% CI 1.22, 3.70, respectively), both of which were significantly modified by history of diabetes. Thirty-d readmissions are attributable to both patient and process-level factors. These data suggest that a lack of post-transplant medication knowledge in high-risk patients drives early hospital readmission.

Incidence, risk factors, and outcomes of opportunistic infections in pediatric renal transplant recipients.

OIs present significant risks to patients following solid organ transplantation. The purpose of this study was to identify risk factors for the development of OIs after kidney transplantation in pediatric patients and to evaluate the impact of OIs on outcomes in this patient population. A single-center retrospective longitudinal cohort analysis including pediatric patients 21 yr of age or younger transplanted from July 1999 to June 2013 at an academic medical center was conducted. Patients were excluded if they received multi-organ transplant. A total of 175 patients were included in the study. Patients who developed OIs were more likely to be female and younger at the time of transplant. A six-factor risk model for OI development was developed. Death, disease recurrence, and PTLD development were similar between groups but trended toward increased incidence in the OI group. Incidence of rejection was significantly higher in the OI group (p = 0.04). Patients who developed OIs had several important risk factors, including younger age, EBV-negative serostatus, CMV donor (+)/recipient (-), biopsy-proven acute rejection, ANC <1000, MMF dose >500 mg/m(2), and any infection. Incidence of rejection was higher in the OI group, but rate of graft loss was not statistically different.

Concern for Lost Income Following Donation Deters Some Patients From Talking to Potential Living Donors.

CONTEXT: Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. OBJECTIVE: To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. DESIGN, SETTING, AND PATIENTS: Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. RESULTS: One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. CONCLUSION: Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

Cardiovascular risk factors contribute to disparities in graft outcomes in African American renal transplant recipients: a retrospective analysis.

Data examining cardiovascular (CV) risk factors in renal transplant recipients (RTRs) and their contribution to the disparity in graft survival between African American (AA) patients and non-AAs is limited. A single-center, retrospective analysis of 1003 adult RTRs from January 1, 2000 to May 1, 2008 to inspect the impact of race on post-transplant CV events, treatment of CV risk factors and their independent influence on graft outcomes was performed. AAs experienced a higher incidence of late graft loss, with 1- and 5-year graft survival rates of 93% and 76% vs 95% and 84% in the non-AA group, respectively. AA patients had a higher prevalence of hypertension (HTN) and diabetes mellitus (DM) and demonstrated reduced control of DM post-transplant (AA 74% vs non-AA 82%, p = 0.053). Multivariate analysis for graft survival indicated acute rejection, delayed graft function (DGF) and incidence of CV events were significant risk factors for graft failure, while the use of beta-blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARBs) and 3-hydroxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase inhibitors were protective. In conclusion, after controlling for CV risk factors and events, race did not have an independent effect on outcomes, suggesting CV risk factors and events contribute to this disparity. Clinical summary. AAs experienced a higher rate of graft failure and CV events; after adjusting for multiple immunological and CV risk factors, race no longer remained an independent risk factor for post-transplant CV events or graft failure; although disparities in post-transplant outcomes remain, race alone does not account for the disparity; the racial disparity is due to the higher incidence of DGF and acute rejection, as well as traditional CV risk factors, including HTN and DM.

African American kidney transplant patients' perspectives on challenges in the living donation process.

CONTEXT: The increasing shortage of deceased donor kidneys suitable for African Americans highlights the critical need to increase living donations among African Americans. Little research has addressed African American transplant recipients' perspectives on challenges and barriers related to the living donation process. OBJECTIVE: To understand the perspectives of African American recipients of deceased and living donor kidney transplants on challenges, barriers, and educational needs related to pursuing such transplants. PARTICIPANTS AND DESIGN: A mixed-method design involved 27 African American kidney recipients (13 male) in 4 focus groups (2 per recipient type: 16 African American deceased donor and 11 living donor recipients) and questionnaires. Focus group transcripts were evaluated with NVivo 10.0 (QSR, International) by using inductive and deductive qualitative methods along with crystallization to develop themes of underlying barriers to the living donor kidney transplant process and were compared with the questionnaires. RESULTS: Four main themes were identified from groups: concerns, knowledge and learning, expectations of support, and communication. Many concerns for the donor were identified (eg, process too difficult, financial burden, effect on relationships). A general lack of knowledge about the donor process and lack of behavioral skills on how to approach others was noted. The latter was especially evident among deceased donor recipients. Findings from the questionnaires on myths and perceptions supported the lack of knowledge in a variety of domains, including donors' surgical outcomes risks, costs of surgery, and impact on future health. Participants thought that an educational program led by an African American recipient of a living donor kidney transplant, including practice in approaching others, would increase the likelihood of transplant-eligible patients pursuing living donor kidney transplant.

Sustainability of improvements in medication adherence through a mobile health intervention.

Context-Very few patient-centered, theory-guided programs for medication adherence and blood pressure control have been conducted in kidney transplant recipients. Objective-To evaluate preliminary indications of sustainability of improved blood pressure in kidney transplant recipients 12 months after completion of a 3-month randomized controlled trial of a mobile health pilot program to improve blood pressure and medication adherence. Participants and Design-A total of 18 of the 19 trial participants were contacted and all consented to inclusion in the retrospective analysis of their medical records showing their clinic-recorded systolic blood pressures at 3, 6, and 12 months following participation in the 3-month trial of a medical regimen self-management intervention. Results-A significant group difference in systolic blood pressure was observed longitudinally, indicating that the intervention group, as compared with the standard-care group, exhibited lower clinic-measured systolic blood pressures at the 12-month posttrial follow-up visit (P= .01). At 12-month follow-up, success in establishing and sustaining control of systolic blood pressure (<131 mm Hg) was greater in the intervention group (50%) than in the control group (11%). Conclusion-Patients in the intervention group continued to exhibit lower systolic blood pressure than did patients in the control group 12 months after the trial ended, suggesting that the intervention may have a durable impact on blood pressure control that most likely reflects sustained medication adherence. These findings will aid in the development of an adequately powered randomized controlled trial to address the sustainable impact of the intervention program on medication adherence and blood pressure control.

Prospective randomized controlled trial of rabbit antithymocyte globulin compared with IL-2 receptor antagonist induction therapy in kidney transplantation.

OBJECTIVE: The aim of this study was to determine the safety and efficacy of induction with rabbit antithymocyte globulin (RATG) compared with interleukin-2 receptor antagonists in a racially diverse kidney transplant patient population under modern immunosuppression. BACKGROUND: The optimal induction therapy in patients at risk for rejection, particularly black recipients, in the modern era of immunosuppression with flow cytometry-based cross-matching is unclear. METHODS: This was a prospective, risk-stratified, randomized, single-center, open-label study of 200 consecutively enrolled patients in a large academic teaching center. Patients were randomized to receive either daclizumab or basiliximab versus RATG for induction in combination with tacrolimus, mycophenolate mofetil, and corticosteroids. Patients were stratified between groups to ensure equal numbers of black, retransplants, high panel reactive antibodies (PRAs) (>20%), and prolonged cold ischemic times (>24 hours) in each group. Primary outcome measure is treatment efficacy defined as the incidence of biopsy-proven acute rejection and estimated creatinine clearance. Patients were followed up for 12 months. Renal transplant recipients were included if they were adult (≥18 years old) and received an allograft from a deceased, living unrelated, or nonhuman leukocyte antigen identical living-related donor. RESULTS: A total of 200 patients (n = 98 in the interleukin-2 receptor antagonists, and n = 102 in the RATG) were enrolled from February 2009 through July 2011. One-year acute rejection rates were low and similar between groups (10% in the interleukin-2 receptor antagonist group vs 6% in the RATG group; P = 0.30). Creatinine clearance was also similar between groups (interleukin-2 receptor antagonist group 56 ± 20 mL/min per 1.73 m2 vs RATG group 55 ± 22 mL/min per 1.73 m2; P = 0.73). Subanalysis of recipient race revealed that in blacks only RATG was protective against 6- and 12-month acute rejection, without an increased risk of infection. Induction did not affect rejection rates according to recipient calculated PRAs; however, RATG was associated with an increased risk of BK virus in low-PRA patients. CONCLUSIONS AND RELEVANCE: RATG induction provides improved protection against early acute rejection in black renal transplant recipients, whereas sensitized patients do not seem to demonstrate a similar benefit from this therapy. This study is registered at Clinicaltrials.gov (NCT00859131).
