Abstract
BACKGROUND Extended-release tacrolimus for prophylaxis of allograft rejection in heart transplant (HT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release (IR-) tacrolimus. We compared long-term efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. METHODS 25 prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 3 years following transplant was compared between groups using non-inferiority analysis. RESULTS LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 16% (90%CI, -37%, -1%, non-inferiority p = 0.002) up to 3 years following heart transplant. Up to 3-years post-transplant, 14 patients remained on once-daily LCPT and 10 patients were switched to IR-tacrolimus due to lack of insurance coverage. There were no significant differences in the rate of chronic kidney disease requiring dialysis, cytomegalovirus requiring treatment, cardiac allograft vasculopathy, and malignancy within 3 years following transplant. CONCLUSION LCPT is non-inferior in efficacy to IR-tacrolimus in heart transplantation with a similar safety profile. Narrowly-constrained FDA labels specific to kidney transplant remain a barrier to consistent access to many immunosuppressant medications for recipients of non-kidney solid organs. We recommend the FDA consider developing facile pathways for expanding the approved label of extended-release tacrolimus formulations to heart transplant recipients.

Abstract
BACKGROUND Medication adherence is essential for long-term success after pediatric organ transplantation. Causes of reduced adherence should be detected early to improve the consequent medication intake. We describe the influence of switching from tacrolimus twice daily (tacrolimus-BID) to tacrolimus once daily (tacrolimus-QD) on medication satisfaction and medication adherence in patients after pediatric heart transplantation. METHODS A retrospective analysis was conducted regarding patient satisfaction and adherence to the immunosuppressant tacrolimus after pediatric heart transplantation, before and after conversion from tacrolimus-BID to tacrolimus-QD, using questionnaires. RESULTS Thirty-eight patients were enrolled (tacrolimus-BID: n = 35, mean age 15.7 ± 5.2 years; tacrolimus-QD: n = 38, mean age 16.2 ± 5.6 years). The amount of unadministered medication in the last 3 months did not differ between the 2 pharmaceutical forms. However, 17% (n = 6) reported unstable tacrolimus trough levels when taking tacrolimus-BID, vs 8% (n = 3) under tacrolimus-QD (P = .453). However, there was no statistically significant difference in the stability of the last 6 trough levels of each patient (P = .074). A total of 57% (n = 20) of patients had subjective side effects before conversion, compared to only 29% (n = 11) after conversion (P = .013). Regarding the intensity of the side effects, 6 patients reported strong/very strong side effects when taking tacrolimus-BID vs 1 patient when taking tacrolimus-QD (P = .250). In addition, the overall satisfaction with the immunosuppressant was higher under tacrolimus-QD (92% vs 83%; P = .508). However, this improvement was statistically not significant and may not be clinically relevant. CONCLUSIONS The amount of forgotten medication was not reduced after conversion from tacrolimus-BID to tacrolimus-QD. However, subjective side effects as well as patient satisfaction improved under tacrolimus-QD.

Abstract
BACKGROUND Nonadherence to immunosuppressives, a risk factor for poor posttransplant outcomes, can be assessed by self-report using the Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS). Available in written and interview versions, and previously validated on content, the BAASIS is widely used in research and clinical practice. The aim of this study was to investigate its psychometric properties. METHODS Using a literature search and our BAASIS database, this meta-analysis identified completed studies in adult transplant recipients whose data were usable to examine the BAASIS' reliability and 3 validity aspects: (1) relationships with other variables (electronic monitoring, other self-report scales, tacrolimus blood-level variability, collateral report, depressive symptoms, psycho-behavioral constructs, and interventions); (2) response processes; and (3) internal structure. Testing used random-effects logistic regressions. RESULTS Our sample included 12 109 graft recipients from 26 studies. Of these 26, a total of 20 provided individual participant data. Evidence of the BAASIS' stability over time supports its reliability. Validity testing of relationships with other variables showed that BAASIS-assessed nonadherence was significantly associated with the selected variables: electronically monitored nonadherence ( P < 0.03), other self- and collaterally-reported nonadherence ( P < 0.001), higher variability in tacrolimus concentrations ( P = 0.02), higher barriers ( P < 0.001), lower self-efficacy ( P < 0.001), lower intention ( P < 0.001), and higher worries ( P = 0.02). Nonadherence also decreased after regimen change interventions ( P = 0.03). Response process evaluation indicated good readability and slightly higher nonadherence with the written version. Structurally, items on taking and timing shared variability. CONCLUSIONS The BAASIS shows good validity and reliability as a self-report instrument to assess medication nonadherence in transplantation.

Abstract
BACKGROUND Successful maintenance of a heart transplant (HTx) graft requires adherence to a triple-drug regimen of immunosuppression. However, achieving adequate adherence can be difficult secondary to complicated dosing regimens, side effects, and mental/emotional barriers. A detailed review of current patterns of adherence to immunosuppression in adult HTx recipients is lacking. OBJECTIVE This systematic review aims to detail the current landscape of adherence to immunosuppression in adult heart transplant patients, including the measurement of adherence, correlates to adherence, health outcomes associated with nonadherence, as well as strategies to improve adherence in HTx patients. METHODS We conducted searches in PubMed MEDLINE, Embase, CENTRAL register of Controlled Trials (Wiley), and Scopus, from inception to March 2020. Studies were eligible if they outlined an aspect of adherence (as noted above in the objective) to immunosuppression in adult HTx patients. The HTx cohort had to contain at least 10 patients and measurement of adherence had to be done with an objective or otherwise validated measure of adherence (e.g. drug levels, automated pill bottles or adherence questionnaires). Two authors independently screened the articles for inclusion, then subsequently reviewed the full texts of the included articles. Data was extracted into standardized forms and bias evaluations were done using the Newcastle-Ottawa or modified Newcastle-Ottawa tools, depending on the study type. The authors followed all guidelines for the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. RESULTS The titles/abstracts of 880 articles were reviewed. Ultimately, 23 articles were included in the final review. The median number of participants was 101, with a range of 19 to 1397. Studies provided information on baseline levels of adherence (17 studies), correlates to adherence (14 studies), health outcomes related to nonadherence (3 studies) and interventions to improve adherence (3 studies). Baseline adherence estimates varied greatly depending on the adherence measure. Multiple significant correlates to nonadherence exist and appear to affect patients with certain sociodemographic backgrounds, those with psychological/psychiatric comorbidities and those with poor support structures. Nonadherence is associated with transplant coronary artery disease and acute late rejection; it may also be associated with long-term mortality. Finally, a simplified dosing regimen with once-a-day tacrolimus as well as use of a mobile phone-based intervention were associated with improved adherence. Bias scores were most deficient due to self-reported outcomes in 18 studies, and lack of controls/adjustments for confounders, in 7 studies. CONCLUSIONS Adherence to immunosuppression in transplant patients varies, but is associated with observable and modifiable factors which are worth addressing. Further high-quality studies regarding strategies to improve adherence are needed in the literature.

Abstract
Extended-release tacrolimus for prophylaxis of allograft rejection in orthotopic heart transplant (OHT) recipients is currently not FDA-approved. One such extended-release formulation of tacrolimus known as LCPT allows once-daily dosing and improves bioavailability compared to immediate-release tacrolimus (IR-tacrolimus). We compared the efficacy and safety of LCPT to IR-tacrolimus applied de novo in adult OHT recipients. Twenty-five prospective recipients on LCPT at our center from 2017 to 2019 were matched 1:2 with historical control recipients treated with IR-tacrolimus based on age, gender, and baseline creatinine. The primary composite outcome of death, acute cellular rejection, and/or new graft dysfunction within 1 year was compared using non-inferiority analysis. LCPT demonstrated non-inferiority to IR-tacrolimus, with a primary outcome risk reduction of 20% (90% CI: -40%, -.5%; non-inferiority P = .001). Tacrolimus trough levels peaked at 2-3 months and were higher in LCPT (median 14.5 vs. 12.7 ng/ml; P = .03) with similar dose levels (LCPT vs. IR-tacrolimus: .08 vs. .09 mg/kg/day; P = .33). Cardiovascular-related readmissions were reduced by 62% (P = .046) in LCPT patients. The complication rate per transplant admission and all-cause readmission rate did not differ significantly. These results suggest that LCPT is non-inferior in efficacy to IR-tacrolimus with a similar safety profile and improved bioavailability in OHT.

Abstract
ER-Tac, taken once per day, is associated with improved adherence. This study examined the potential patient and clinical factors that influence clinicians to convert pediatric patients from immediate-release to ER-Tac. This prospective multi-center observational study followed Canadian pediatric kidney transplant recipients up to 5 years post-transplant. Cox Proportional Hazards Regression was used to examine the influence of factors on conversion to ER-Tac. Sixty-six participants were included in this analysis. For every additional year of age at the time of transplant, the likelihood of conversion was more than doubled (HR 2.54, CI 1.83, 3.54, P < 0.001). The impact of age reduced by three percent for every month after transplant (HR 0.97, CI 0.95, 0.98, P < 0.001). Girls were more likely to be converted than boys (HR 3.78, CI 1.35, 10.6, P 0.01). Adherence measures (MAM-MM and tacrolimus trough variability), individual barriers to adherence, renal function, HLA mismatch, and rejection were not significant predictors of conversion in the final regression model. ER-Tac was preferentially prescribed to older age and female patients. Female sex and adolescence are both associated with worse graft outcomes, but we found no link between individualized markers of adherence/graft risk and conversion. Clinicians appeared to be using demographic features to distinguish patients at perceived higher risk and converted accordingly, without a case-by-case evaluation of who is more susceptible to poor outcomes.

Abstract
Tacrolimus (Tac) is the cornerstone calcineurin inhibitor in transplantation. Extended-release Meltdose formulation (Tac-LCP) offers better bioavailability compared with immediate-release formulation (Tac-IR). We postulated that the less fluctuating pharmacokinetic (PK) profile of Tac-LCP might maintain a sustained inhibition of calcineurin activity (CNA) between dose intervals. Higher concentrations (peak plasma concentration (Cmax )) after Tac-IR may not result in a more potent CNA inhibition due to a capacity-limited effect. This study was aimed at evaluating the pharmacodynamic (PD)/PK profiles of Tac-IR compared with Tac-LCP. An open-label, prospective, nonrandomized, investigator-driven study was conducted. Twenty-five kidney transplant recipients receiving Tac-IR were switched to Tac-LCP. Before and 28 days after conversion, intensive CNA-PD and PK sampling were conducted using ultra-high-performance liquid chromatography-tandem accurate mass spectrometry. PD nonlinear mixed effects model was performed in Phoenix-WinNonlin. Statistically significant higher Cmax (P < 0.001) after Tac-IR did not result in lower CNA as compared with after Tac-LCP (P = 0.860). Tac-LCP showed a statistically more maintained CNA inhibition between dose intervals (area under the effect-time curve from 0 to 24 hours (AUE0-24h )) compared with Tac-IR, in which CNA returned to predose levels after 4 hours of drug intake (373.8 vs. 290.5 pmol RII·h/min·mg prot, Tac-LCP vs. Tac-IR; P = 0.039). No correlation was achieved between any PD and PK parameters in any formulations. Moreover, Tac concentration to elicit a 50% of the maximum response (half-maximal inhibitory concentration) was 9.24 ng/mL. The higher Cmax after Tac-IR does not result in an additional CNA inhibition compared with Tac-LCP attributable to a capacity-limited effect. Tac-LCP may represent an improvement of the PD of Tac due to the more sustained CNA inhibition during dose intervals.

Abstract
BACKGROUND Lung transplantation (LTx) requires a calcineurin inhibitor-based immunosuppressive regimen. A once daily (QD) tacrolimus regimen was developed to increase medication adherence. However, data concerning its safety and efficacy in LTx are lacking. METHODS In this prospective study, stable LTx patients were consecutively converted from twice daily (BID) tacrolimus to QD tacrolimus on a 1 mg:1 mg basis. Trough level (Cmin), renal function, cholesterol, fasting glucose, potassium and lung function were monitored six months before and up to one year after conversion. Adherence and its barriers were assessed by self-reported questionnaires (Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS) and Identification of Medication Adherence Barriers questionnaire (IMAB)) and blood-based assays (mean Cmin and coefficient of variation (CV)). RESULTS We included 372 patients, in whom we observed a decrease in tacrolimus Cmin of 18.5% (p < 0.0001) post-conversion, requiring subsequent daily dose adaptations in both cystic fibrosis (CF) (n = 72) and non-CF patients (n = 300). We observed a small decrease in eGFR one year post-conversion (p = 0.024). No significant changes in blood creatinine, potassium, fasting glucose, cholesterol or rate of lung function decline were observed. In a subgroup of 166 patients, significantly fewer patients missed doses (8.4% vs. 19.3%, p = 0.016) or had irregular intake post-conversion (19.3% vs. 32.5%, p = 0.019). Mean Cmin and CV, as well as the total number of barriers, also decreased significantly post-conversion. CONCLUSIONS In LTx, conversion from BID to QD tacrolimus (1 mg:1 mg) requires close monitoring of tacrolimus Cmin. QD tacrolimus after transplantation is safe with respect to renal function, metabolic parameters and allograft function and improves LTx recipient adherence.

Abstract
BACKGROUND In this study we investigated medication adherence of kidney transplant patients (KTPs) to an immediate-release tacrolimus (IR-T) regimen and, after conversion, to a prolonged-release tacrolimus (PR-T) regimen in routine clinical practice. METHODS This was a noninterventional, observational, multicenter Swedish study. We included adult KTPs with stable graft function, remaining on IR-T or converting from IR-T to PR-T. Data were collected at baseline, and months 3, 6, and 12 postbaseline. The primary endpoint was adherence using the Basel Assessment of Adherence to Immunosuppressive Medication Scale (BAASIS). Secondary assessments included tacrolimus dose and trough levels, clinical laboratory parameters (eg, estimated glomerular filtration rate), and adverse drug reactions (ADRs). RESULTS Overall, 233 KTPs were analyzed (PR-T, n = 175; IR-T, n = 58). Mean change in PR-T dose from baseline (4.8 mg/d) to month 12 was -0.2 mg/d, and for IR-T (4.2 mg/d) was -0.4 mg/d; tacrolimus trough levels remained similar. Overall adherence was similar between baseline and month 12 in both groups (PR-T: 54.4% vs 57.0%, respectively; IR-T: 65.5% vs 69.4%); timing adherence followed a similar pattern. The probability of taking adherence improved between baseline and month 12 (odds ratio, 1.97; P = .0092) in the PR-T group only. Mean BAASIS visual analog scale score at baseline was 94.3 ± 11.1% (PR-T) and 95.3 ± 7.6% (IR-T), and >95% at subsequent visits. Laboratory parameters remained stable. Eight (4.6%) patients receiving PR-T (none receiving IR-T) had ADRs considered probably/possibly treatment-related. CONCLUSION Disparity existed between high, patient-perceived and low, actual adherence. Overall adherence to the immunosuppressive regimen (measured by BAASIS) did not improve significantly over 12 months in stable KTPs converting to PR-T or remaining on IR-T; renal function remained stable.

Abstract
BACKGROUND Lifelong adherence with post-transplant immunosuppression is challenging, with nonadherence associated with greater acute rejection (AR) risk. METHODS This retrospective study evaluated conversion from immediate-release tacrolimus (IRT) to prolonged-release tacrolimus (PRT), between January 2008 and December 2012 in stable adult heart transplant recipients. Cumulative incidence rate (IR) of AR and infection pre- and postconversion, safety, tacrolimus dose and trough levels, concomitant immunosuppression, and PRT discontinuation were analyzed (intention-to-treat population). RESULTS Overall, 467 patients (mean age, 59.3 [SD, 13.3] years) converted to PRT at 5.1 (SD, 4.9) years post transplant and were followed for 3.4 (SD, 1.5) years. During the 6 months post conversion, 5 patients (1.1%; 95% CI, 0.35%-2.48%) had an AR episode and IR was 2.2/100 patient-years (95% CI, 0.91-5.26). Incidence of rejection preconversion varied by time from transplant to conversion. Infection IR was similar post- and preconversion (9.2/100 patient-years [95% CI, 7.4-11.3] vs 10.6/100 patient-years [95% CI, 8.8-12.3], respectively; P = .20). Safety variables remained similar post conversion. The IR of mortality/graft loss was 2.3/100 patient-years (95% CI, 1.7-3.1). CONCLUSIONS Conversion from IRT to PRT in heart transplant recipients in Spain was associated with no new safety concerns and appropriate immunosuppressive effectiveness.

Abstract
OBJECTIVES To estimate the real-world (RW) impact of adherence to once-daily (QD: rivaroxaban and edoxaban) and twice-daily (BID: apixaban and dabigatran) non-vitamin K antagonist (NOACs) on the risk of stroke and major bleeding (MB) among non-valvular atrial fibrillation (NVAF) patients. METHODS First, claims from the Optum Clinformatics Data Mart database (July 2012-December 2016) were analyzed. Adult NVAF patients with ≥2 NOAC dispensings (index date) were included. The relationship between NOAC adherence (proportion of days covered ≥80%) and stroke/MB 1-year post-index was evaluated using adjusted Cox proportional hazards models. Second, the natural logarithm of hazard ratios (HRs) was multiplied to a literature-derived mean adherence difference between QD and BID NOACs yielding stroke and MB rates. Third, these rates were multiplied by 1-year Kaplan-Meier rates of stroke and MB which yielded the number of strokes prevented and MBs caused. Annual cost savings were evaluated using literature-based stroke ($81,414/patient) and MB ($63,905/patient) cost estimates. RESULTS In total, 54,280 patients were included. HRs for adherent vs non-adherent patients were 0.67 (p < .001) for stroke and 1.09 (p = .179) for MB. The claims-derived 1-year Kaplan-Meier rates were 3.0% and 3.4% for strokes and MBs, respectively. For 100,000 AF patients, 64 strokes were prevented (p < .001), and a non-significant number of MBs (n = 15, p < .191) were caused by QD vs BID NOACs annually, which leads to cost savings estimated at $58 million for QD NOACs. CONCLUSION QD NOACs prevented a significant number of strokes and caused no significant increase in MBs compared to BID NOACs, which leads to significant net cost savings for NVAF patients in the US.

Abstract
BACKGROUND This 24-week, multicenter, randomized, exploratory, comparative, open-label, phase-IV study assessed the safety and efficacy of prolonged-release tacrolimus (PR-T) with reduced-dose versus standard-dose corticosteroids in stable kidney transplant recipients in Korea after converting from cyclosporine-based therapy. METHODS At baseline, patients were converted from cyclosporine-based to PR-T-based immunosuppression and randomized (1:1) to receive either corticosteroids maintained at prestudy dose (standard-dose group) or tapered from week 4 to 50% of the prestudy dose by week 12 (reduced-dose group). Patients were seen at baseline and weeks 1, 4, 12, and 24. The primary endpoint was change in estimated glomerular filtration rate (Modification-of-Diet-in-Renal-Disease-4) between baseline and week 24. Secondary endpoints included either acute rejection or patient-reported satisfaction with PR-T. Adverse events (AEs) were recorded. RESULTS Overall, 150 patients were randomized into a reduced-dose group (n = 73) and a standard-dose group (n = 77). At week 24, mean ± standard deviation for corticosteroid dose was 2.5 ± 0.9 mg and 5.0 ± 1.3 mg, respectively. Mean change in estimated glomerular filtration rate from baseline to week 24 was +1.5 ± 9.1 mL/min/1.73 m2 (P = .1567) and +3.4 ± 10.6 mL/min/1.73 m2 (P = .0065), respectively, and not significantly different between groups. There were no acute rejection episodes. Most respondents (>70%) considered PR-T more convenient than cyclosporine. AE incidence was similar between groups. The most common AEs experienced by ≥3% of patients in either treatment group were gastrointestinal events (20.8% and 28.6% of patients receiving reduced- and standard-dose corticosteroids, respectively). Most AEs in both treatment groups were mild or moderate in severity. CONCLUSION Renal function was maintained following conversion from cyclosporine to PR-T, irrespective of corticosteroid regimen; PR-T enables reduced corticosteroid dosage.

Abstract
BACKGROUND Nonadherence (NA) to immunosuppressive (IS) medications after organ transplant is a major risk factor for transplant failure, morbidity, and treatment costs. This study examined the association between feelings of indebtedness and guilt toward the donor, and IS medication adherence among HTx patients. METHODS In this cross-sectional, descriptive, correlational study, a convenience sample of 102 HTx patients, from the outpatient facility of a tertiary medical center in Israel, completed the BAASIS, a validated instrument for assessing adherence, and reported their feelings of indebtedness and guilt toward the donor. RESULTS Missing a dose or skipping two or more doses, taking medication >2 hours before or after the recommended dosing time, altering the prescribed amount, or completely stopping the IS treatment in the last 4 weeks, characterized 64 patients (64%). The highest score received the item "timing nonadherence," characterizing 58 patients (56.9%). Age, waiting time, and time since transplant, guilt feelings, and indebtedness to donor explained 17% (R2 =.17) of the variance in adherence (χ2(5) =13.22, P=.021), with age, time since transplant, and guilt feelings significantly explaining adherence. CONCLUSION Physicians and nurses should inquire about the presence of guilt feelings, as they might be associated with NA to medications after HTx.

Abstract
BACKGROUND Anxiety and depression are common after heart transplantation. This study aimed to pilot test the feasibility of a clinical model of psychological care for heart transplant recipients. The model of care involved nurse-led screening for anxiety and depression followed by referral for a course of telephone-delivered cognitive behaviour therapy as well as co-ordination of communication with on-going specialist and primary care services. METHODS A pilot randomised controlled trial was conducted. Heart transplant recipients who self-reported at least mild anxiety or depressive symptoms were randomised (defined as a score higher than 5 on the Patient Health Questionnaire-9 or the Generalized Anxiety Disorder-7 [GAD-7], or a score higher than 20 on the Kessler Psychological Distress Scale [K10]). The primary outcome was assessment of feasibility of conducting a larger trial, which included identification of recruitment and attrition rates as well as the acceptability of the intervention. Follow-up was conducted at 9 weeks and 6 months. RESULTS One hundred twenty-two of the 126 (97 %) heart transplant recipients assessed on their attendance at the outpatient clinic met the study eligibility criteria. Of these patients, 88 (72 %) agreed to participate. A moderate proportion of participants (n = 20; 23 %) reported at least mild symptoms of anxiety or depression. Five participants were excluded because they were currently receiving psychological counselling, two withdrew before randomisation and the remaining 13 were randomised (seven to intervention and six to usual care). The majority of the randomised participants were male (n = 9; 69 %) and aged over 60 (range 35-73). Median length of time post-transplant was 9.5 years (ranging from 1 to 19 years). On enrolment, 3 randomised participants were taking anti-depressants. One intervention group participant withdrew and a further 3 (50 %) declined the telephone-delivered CBT sessions; all because of restrictions associated with physical illnesses. Attrition was 30 % at the 6 month follow-up time-point. CONCLUSIONS Due to the poor acceptability of telephone-delivered cognitive behavioural therapy observed in our sample, changes to intervention components are indicated and further pilot testing is required.

Abstract
BACKGROUND Calcineurin inhibitors (CNI) have failed to improve long-term outcomes in renal transplantation. Anti-proliferative and anti-angiogenic effects of mammalian target of rapamycin inhibitors (m-TOR) without nephrotoxicity could improve long-term survival in selected transplant recipients. METHODS We examined the evolution of 98 low-immunological risk renal transplant recipients on m-TOR monotherapy: 7 patients had induction without CNI and 91 were switched to m-TOR at 12 (p25-p75: 4-36) months after transplant. RESULTS Median follow-up time was 46 (p25-p75: 28.5-72.0) months. Fifteen recipients dropped out of the study (15.3%): 8 patients (8.2%) had to change their immunosuppressive treatment because of complications and 7 (7.1%) lost their grafts as a result of chronic rejection (4 cases) or death with a functioning graft (3 cases). At the end of follow-up, 83 of 98 (84.6%) recipients remained on monotherapy. The rates of recipient and graft survivals were 100% and 98.8% at 2 years and 96.9% and 93.5% at 4 years; the percentages of patients on monotherapy after 2 and 4 years were 95.2% and 85.2%, respectively. Renal function improved significantly and proteinuria decreased but not significantly. Those patients switched to m-TOR significantly received more erythropoietin, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and hypotensive agents than before starting m-TOR, whereas there were no significant changes related to the use of statins, body weight, or percentage of diabetic patients. No case of non-compliance was reported. CONCLUSIONS This study supports the safety and efficacy of monotherapy with m-TOR in selected renal transplant recipients.

Abstract
Background Tacrolimus is metabolized by cytochrome P450 (CYP) 3A4 and 3A5. We investigated the influence of CYP3A5 polymorphism and concurrent use of azole antifungal agents (AZ) on the pharmacokinetics of a once-daily modified-release tacrolimus formulation (Tac-QD) in patients after hematopoietic stem cell transplantation (HSCT). Design and methods Twenty-four patients receiving allogeneic HSCT were enrolled. Genotyping for CYP3A5*3 was done by a PCR-restriction fragment length polymorphism method. Trough blood concentrations (C0) of tacrolimus were measured by chemiluminescence magnetic microparticle immunoassay. Continuous infusion of tacrolimus was administered from the day before transplantation and was switched to Tac-QD after adequate oral intake. Results Thirteen patients had a CYP3A5*3/*3 genotype, and 11 patients had a CYP3A5*1/*1 or *1/*3 genotype. No significant difference was observed in daily dosages and the C0 of tacrolimus between the two genotype groups without AZ. However, in patients who were co-administered AZ, the C0 values of tacrolimus were higher in patients with the CYP3A5*3/*3 allele than with the CYP3A5*1 allele (P = 0.034), although daily doses of Tac-QD in patients with CYP3A5*3/*3 were significantly lower than those with the CYP3A5*1 allele (P = 0.041). The cumulative incidence of acute kidney injury was higher in patients with the CYP3A5*3/*3 than with the CYP3A5*1 allele when AZ was co-administered. The decrement for daily dosage of Tac-QD was significantly greater in patients expressing the CYP3A5*3/*3 than the CYP3A5*1 allele. Conclusions CYP3A5 genotyping may be useful for safe and effective immunosuppressive therapy with Tac-QD in HSCT patients in whom the use of AZ is anticipated.

Abstract
We describe longitudinal results in a cohort of pediatric liver transplant patients successfully minimized to once daily CNI monotherapy for longer than five yr and assess changes in liver biochemistries and liver histology. A retrospective chart review of all pediatric liver transplant patients at a single center was performed. Biopsies and serum biochemistries (AST, ALT, total bilirubin, direct bilirubin, INR, creatinine) are reported at time points: PM, five-yr, seven-yr, and nine-yr post-minimization. Biopsies were assessed for inflammation and fibrosis using Ishak and Batts grading systems. Successful minimization to daily CNI monotherapy was defined as normal liver enzymes with no episodes of rejection. Thirty-three patients have successfully remained on once daily CNI for >5 yr, and 19/33 of these patients have serial liver biopsies available for review. We report on the clinical and histological findings of these 19 patients. All 19 patients continue to have normal liver biochemistries. On post-minimization biopsies, fibrosis progressed by ≥2 stages in one patient (5.3%) despite normal liver biochemistries. Carefully selected patients can tolerate minimization to once daily CNI monotherapy as few have progression of fibrosis.

Abstract
Patient acceptability of a medicinal product is a key aspect in the development and prescribing of medicines. Children and older adults differ in many aspects from the other age subsets of population and require particular considerations in medication acceptability. This review highlights the similarities and differences in these two age groups in relation to factors affecting acceptability of medicines. New and conventional formulations of medicines are considered regarding their appropriateness for use in children and older people. Aspects of a formulation that impact acceptability in these patient groups are discussed, including, for example, taste/smell/viscosity of a liquid and size/shape of a tablet. A better understanding of the acceptability of existing formulations highlights opportunities for the development of new and more acceptable medicines and facilitates safe and effective prescribing for the young and older populations.

Abstract
Background. Retrospective, observational studies link high phosphate with mortality in dialysis patients. This generates research hypotheses but does not establish “cause-and-effect.” A large randomised controlled trial (RCT) of about 3000 patients randomised 50 : 50 to lower or higher phosphate ranges is required to answer the key question: does reducing phosphate levels improve clinical outcomes? Whether such a trial is technically possible is unknown; therefore, a study is necessary to inform the design and conduct of a future, definitive trial. Methodology. Dual centre prospective parallel group study: 100 dialysis patients randomized to lower (phosphate target 0.8 to 1.4 mmol/L) or higher range group (1.8 to 2.4 mmol/L). Non-calcium-containing phosphate binders and questionnaires will be used to achieve target phosphate. Primary endpoint: percentage successfully titrated to required range and percentage maintained in these groups over the maintenance period. Secondary endpoints: consent rate, drop-out rates, and cardiovascular events. Discussion. This study will inform design of a large definitive trial of the effect of phosphate on mortality and cardiovascular events in dialysis patients. If phosphate lowering improves outcomes, we would be reassured of the validity of this clinical practice. If, on the other hand, there is no improvement, a reassessment of resource allocation to therapies proven to improve outcomes will result. Trial Registration Number. This trial is registered with ISRCTN registration number ISRCTN24741445.

Abstract
The enduring success of lung transplantation is built on the use of immunosuppressive drugs to stop the immune system from rejecting the newly transplanted lung allograft. Most patients receive a triple-drug maintenance immunosuppressive regimen consisting of a calcineurin inhibitor, an antiproliferative and corticosteroids. Induction therapy with either an antilymphocyte monoclonal or an interleukin-2 receptor antagonist are prescribed by many centres aiming to achieve rapid inhibition of recently activated and potentially alloreactive T lymphocytes. Despite this generic approach acute rejection episodes remain common, mandating further fine-tuning and augmentation of the immunosuppressive regimen. While there has been a trend away from cyclosporine and azathioprine towards a preference for tacrolimus and mycophenolate mofetil, this has not translated into significant protection from the development of chronic lung allograft dysfunction, the main barrier to the long-term success of lung transplantation. This article reviews the problem of lung allograft rejection and the evidence for immunosuppressive regimens used both in the short- and long-term in patients undergoing lung transplantation.

Abstract
BACKGROUND Immunosuppressive therapy after orthotopic liver transplantation (OLT) requires a high degree of patient compliance to guarantee safety and avoid side effects. In 2007, prolonged-release tacrolimus was launched in Europe to improve compliance. In this prospective observational crossover single-center trial, we analyzed effects and side effects of prolonged-release tacrolimus in OLT patients. METHODS LT patients at our center were included if they were older than l8 years of age, had had the procedure at least 6 months prior, and were outpatients currently on twice-daily tacrolimus. Patients were observed for 6 months before switching to once-daily tacrolimus. Patient history, clinical examination, and laboratory examinations were recorded on inclusion as well as after 3, 6, 9, 12, and 18 months. RESULTS The rates of rejection, hypertension, hypercholesterolemia, and diabetes mellitus were compared during twice-daily and once-daily tacrolimus. Similarly, laboratory parameters were identical during both periods with the exception of glycated hemoglobin, which was significantly elevated under once-daily tacrolimus (P = .00l). CONCLUSION Converting patients to extended-release tacrolimus with was safe in terms of rejection, hypertension, and hypercholesterolemia as well as renal and liver functions. Further investigations concerning pharmacokinetics and glucose metabolism will be needed to evaluate prolonged-release tacrolimus.

Abstract
PURPOSE The aim of this study was to determine the prevalence of nonadherence in a cohort of renal transplant recipients (RTRs) and to evaluate prospectively whether more intense clinical surveillance and reduced pill number enhanced adherence. PATIENTS AND METHODS The study was carried out in 310 stable RTRs in whom adherence, life satisfaction, and transplant care were evaluated by specific questionnaires (time 0). The patients under tacrolimus (TAC; bis in die [BID]) were then shifted to once-daily TAC (D-TAC) to reduce their pill burden (Shift group) and were followed up for 6 months to reevaluate the same parameters. Patients on cyclosporin or still on BID-TAC constituted a time-control group. RESULTS The prevalence of nonadherence was 23.5% and was associated with previous rejection episodes (P<0.002), and was inversely related to Life Satisfaction Index, anxiety, and low glomerular filtration rate (minimum P<0.03). Nonadherent patients were significantly less satisfied with their medical care and their relationships with the medical staff. A shift from BID-TAC to D-TAC was performed in 121 patients, and the questionnaires were repeated after 3 and 6 months. In the Shift group, a reduction in pill number was observed (P<0.01), associated with improved adherence after 3 and 6 months (+36%, P<0.05 versus basal), with no change in controls. Decreased TAC trough levels after 3 and 6 months (-9%), despite a slight increase in drug dosage (+6.5%), were observed in the Shift group, with no clinical side effects. CONCLUSION The reduced pill burden improves patients' compliance to calcineurin-inhibitors, but major efforts in preventing nonadherence are needed.

Abstract
Background Modified-release tacrolimus (TAC) is a new, once-daily oral formulation of the established immunosuppressive agent TAC. This study evaluated long-term patient adherence, as well as safety and efficacy, in stable patients after heart transplantation (HTx) who switched from a conventional twice daily calcineurin inhibitor-based regimen (TAC or cyclosporine A [CsA]) to a once-daily modified-release TAC regimen. Methods Stable patients were switched from conventional TAC or CsA (twice-daily dosing) to modified-release TAC (once-daily dosing) according to manufacturer’s recommendations using a pre-experimental design. Self-reported adherence was assessed at baseline and 8 months after the switch with the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS). Additionally, routine laboratory values were analyzed 8 months after switch. Results Of 76 patients (58 male, 18 female) initially included, 72 were available for statistical analysis, as modified-release TAC was discontinued due to diarrhea in one patient and gastrointestinal discomfort in three patients. Overall nonadherence at baseline for any of the four BAASIS items was 75.0% versus 40.3% after 8 months (P<0.0001). After 8 months, adherence was improved in 41 patients (56.9%), unchanged in 27 (37.5%), and reduced in four patients (5.6%). The BAASIS visual analog scale score improved significantly from 87.0% ± 13.5% to 97.5% ± 5.7% (P<0.0001). No significant changes were observed for hematological, renal, or liver function parameters after 8 months (all P=not significant). Conclusion To our knowledge, this is the first study in stable patients after HTx to demonstrate a significant improvement in long-term (ie, 8-month) patient adherence after the switch to modified-release TAC. Modified-release TAC was generally well tolerated. Further studies are currently underway to investigate long-term safety after HTx of various calcineurin inhibitors for prevention of rejection and occurrence of side effects.

Abstract
BACKGROUND Adherence to immunosuppressive therapy, which is important to prevent rejection after organ transplantation, is influenced by satisfaction of patients with their medication regimen. OBJECTIVE We investigated the effect of introducing a simplified medication regimen for renal transplant patients on treatment satisfaction, in particular, convenience. METHODS In a prospective cohort study, treatment was switched from tacrolimus twice daily to tacrolimus once daily with a simultaneous change to a once-daily formulation of other drugs when applicable. Treatment satisfaction was measured in 75 participants with the validated Treatment Satisfaction Questionnaire for Medication version II. RESULTS The treatment convenience score increased from a mean (SD) of 66.0 (14.5) to 78.5 (14.5) (P < 0.001). The mean (SD) daily number of medication ingestion time points diminished from 2.4 (0.7) to 1.6 (0.7) (P < 0.001), and the mean (SD) daily number of tablets decreased from 12.4 (3.3) to 9.1 (2.6) (P < 0.001). The self-reported adherence to the medication regimen increased from 79.7% to 94.6% (P < 0.001). CONCLUSIONS The introduction of a simplified medication regimen enabled by the use of a once-daily formulation of tacrolimus increases treatment convenience after renal transplantation. This regimen had a beneficial effect on self-reported adherence.

Abstract
BACKGROUND Compliance with immunosuppressive therapy plays a major role in the long-term success of liver transplantation. Thus, the development of strategies to promote compliance of liver transplant patients and its evaluation over time are of particular interest. OBJECTIVE The main objective of this study was to compare medication compliance rates among liver transplant patients over time after transplantation where switched from a twice- to once-daily tacrolimus-based regimen. METHODS Sixty-five liver transplant patients being administered tacrolimus-based therapy were classified into three subgroups with regard to time posttransplantation. Medication compliance with tacrolimus-based therapy was measured using an electronic medication event monitoring system over a 12-month period: for 6 months tacrolimus was administered twice-daily and for 6 months, once-daily. Dosing, taking, and timing compliance as well as drug holidays were compared intra-individually between twice- and once-daily intake and among the three subgroups. In addition, patient compliance and quality of life were evaluated using questionnaires. RESULTS A per protocol analysis of electronically obtained data showed 63 patients to be eligible. The resulting dosing, taking, and timing compliance rates of the patients were higher during the once-daily dosing period. No significant differences in compliance rates with tacrolimus therapy were observed among three subgroups independent of the dosing regimen. More patients failed the correct timing of the evening compared to the morning dose. Missing doses occurred particularly during weekends. Compliance variables measured by questionnaires (Morisky score, self-report, Medication Experience Scale for Immunosuppressants (MESI) score) and the Hospital Anxiety and Depression Scale score were similar in the two dosing periods. The short-form health survey (SF-36) score was higher with once-daily intake. CONCLUSION The high measured compliance rates did not vary significantly dependent upon the time after transplantation. Nevertheless, compliance rates were greater using once-daily tacrolimus dosing.

Abstract
OBJECTIVES To assess the impact of reduced frequency of oral therapies from multiple-dosing schedules to a once-daily (OD) dosing schedule on adherence, compliance, persistence, and associated economic impact. METHODS A meta-analysis was performed based on relevant articles identified from a comprehensive literature review using MEDLINE® and Embase®. The review included studies assessing adherence with OD, twice-daily (BID), thrice-daily (TID), and four-times daily (QID) dosing schedules and costs associated with optimal/suboptimal adherence among patients with acute and chronic diseases. Effect estimates across studies were pooled and analyzed using the DerSimonian and Laird random-effect model. RESULTS Forty-three studies met inclusion criteria, and meta-analyzable data were available from 13 studies. The overall results indicated that OD schedules were associated with higher adherence rates (odds ratio [OR] 3.07, 95% confidence interval [CI] 1.80-5.23; P < 0.001 for OD versus > OD dosing) and compliance rates (OR 3.50, 95% CI 1.73-7.08; P < 0.001 for OD versus > OD dosing); persistence rates showed the same direction but were not statistically significant (OR 1.43, 95% CI 0.62-3.29; P = 0.405 for OD versus BID dosing). Results for each of the conditions were consistent with those observed overall with respect to showing the benefits of less frequent dosing. From a health economic perspective, higher adherence rates with OD relative to multiple dosing in a number of conditions were consistently associated with corresponding lower costs of health care resources utilization. CONCLUSION Current meta-analyses suggested that across acute and chronic disease states, reducing dosage frequency from multiple dosing to OD dosing may improve adherence to therapies among patients. Improving adherence may result in subsequent decreases in health care costs.

Abstract
BACKGROUND With effective agents available to prevent posttransplantation acute organ rejection, medication adherence becomes a key factor for successful treatment outcomes after renal transplantation. A once-daily, modified-release oral formulation of tacrolimus has been developed to simplify dosing and improve medication adherence. METHODS Adherence Measurement in Stable Renal Transplant Patients Following Conversion From Prograft to Advagraf is a randomized multicenter controlled trial to evaluate adherence between a tacrolimus once-daily regimen and a tacrolimus twice-daily regimen using an electronic monitor to document drug intake. After enrolment, all patients continued the twice-daily regimen for 3 months and then were randomized 2:1 between the two formulations and followed for 6 months. Adherence was decomposed into patients' persistence and implementation of each regimen. RESULTS Two hundred nineteen patients (45% male; 3±2 years after transplantation) were analyzed (145 once daily and 74 twice daily). At 6 months after randomization, 81.5% of the once-daily group and 71.9% of the twice-daily group remained persistent with the treatment (P=0.0824). Among patients who remained engaged with the regimen, 88.2% of the once-daily group and 78.8% of the twice-daily group (P=0.0009) took the prescribed number of daily doses. When the patients took the twice-daily regimen, the average percentage of missed doses was 11.7% in the morning and 14.2% in the evening (P=0.0035). CONCLUSIONS Regimen implementation of tacrolimus once daily is significantly superior to the twice-daily regimen. There was a residual prevalence of suboptimal adherence that will have to be countered by means other than reformulation and regimen simplification. Electronically compiled dosing histories provide detailed data on patient adherence that can be used for efficient medication management.

Abstract
We report on a 25-year-old female heart transplant patient who presented with recurrent episodes of cellular rejection due to decreased adherence to immunosuppressive therapy. She received a heart transplantation in 1994 when she was 10 years old. In order to improve her adherence to immunosuppressive therapy, switching to the once-daily extended-release formulation of tacrolimus was performed in a step-wise fashion. First, the twice-daily formulation of cyclosporin A was replaced with the twice-daily preparation of tacrolimus. When the trough blood levels of tacrolimus reached a plateau in the range of 5.0 ng/mL, it was changed to the once-daily extended-release formulation of tacrolimus after confirming the absence of new rejection episodes. There were no significant changes in renal function before and after the switch. After being discharged from the hospital, the patient made significant advancements in adherence to immunosuppressive therapy. Her subsequent clinical course was uneventful, with no adverse events observed. Most patients who undergo solid organ transplantation must receive lifelong immunosuppressive therapy. This case demonstrates that conversion to the extended-release formulation of tacrolimus from other calcineurin inhibitor preparations is a reasonable choice to consider in the management of compromised immunosuppressive therapy adherence in heart transplant patients during the late posttransplant period.

Abstract
Nonadherence is a critical issue in transplantation. Recently, Astellas designed a once-daily-extended release formulation of tacrolimus (Tac). Despite initial reports showing bioequivalence of Tac once-daily (Advagraf) with the original formulation requiring twice-daily intake (Tac twice-daily, Prograf), several groups have now shown a sustained decrease in Tac exposure upon conversion from Prograf to Advagraf. Here, we discuss the possible reasons for this observation and how it could affect the expected benefits of Advagraf, and we comment on the fact that a similar lack of bioequivalence might prevail with generic immunosuppressive drugs.
