Noncompliance in organ transplant recipients: a literature review

Expanding the access to kidney transplantation: Strategies for kidney transplant programs

Kidney transplantation is the most successful kidney replacement therapy available, resulting in improved recipient survival and societal cost savings. Yet, nearly 70 years after the first successful kidney transplant, there are still numerous barriers and untapped opportunities that constrain the access to transplant. The literature describing these barriers is extensive, but the practices and processes to solve them are less clear. Solutions must be multidisciplinary and be the product of strong partnerships among patients, their networks, health care providers, and transplant programs. Transparency in the referral, evaluation, and listing process as well as organ selection are paramount to build such partnerships. Providing early culturally congruent and patient-centered education as well as maximizing the use of local resources to facilitate the transplant work up should be prioritized. Every opportunity to facilitate pre-emptive kidney transplantation and living donation must be taken. Promoting the use of telemedicine and kidney paired donation as standards of care can positively impact the work up completion and maximize the chances of a living donor kidney transplant.

Challenges with non-descriptive compliance labeling of end-stage renal disease patients in accessibility for renal transplantation

Non-descriptive and convenient labels are uninformative and unfairly project blame onto patients. The language clinicians use in the Electronic Medical Record, research, and clinical settings shapes biases and subsequent behaviors of all providers involved in the enterprise of transplantation. Terminology such as noncompliant and nonadherent serve as a reason for waitlist inactivation and limit access to life-saving transplantation. These labels fail to capture all the circumstances surrounding a patient's inability to follow their care regimen, trivialize social determinants of health variables, and bring unsubstantiated subjectivity into decisions regarding organ allocation. Furthermore, insufficient Medicare coverage has forced patients to ration or stop taking medication, leading to allograft failure and their subsequent diagnosis of noncompliant. We argue that perpetuating non-descriptive language adds little substantive information, increases subjectivity to the organ allocation process, and plays a major role in reduced access to transplantation. For patients with existing barriers to care, such as racial/ethnic minorities, these effects may be even more drastic. Transplant committees must ensure thorough documentation to correctly encapsulate the entirety of a patient's position and give voice to an already vulnerable population.

Association of the Stanford Integrated Psychosocial Assessment for Transplant and 1-Year Outcome of Living Kidney Transplantation in Japan

BACKGROUND

Because most kidney transplantations in Japan are performed on the basis of living donors, after-transplant outcomes should achieve optimum results, overcoming participants' possible reduced adherence.

OBJECTIVE

To investigate the association between the Japanese version of the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT-J) and outcomes, 1 year after the patient's living kidney transplant (LKT).

METHODS

The prospective cohort study was undertaken at Tokyo Women's Medical University Hospital from January 2020 to July 2021, with a 1-year follow-up period. The SIPAT-J assesses 18 psychosocial risk factors: (1) Patient's Readiness Level and Illness Management (SIPAT A), (2) Social Support System Level of Readiness (SIPAT B), (3) Psychological Stability and Psychopathology (SIPAT C), and (4) Lifestyle and Effect of Substance Use (SIPAT D). The evaluators, a psychiatrist and 3 clinical psychologists, conducted an independent, blinded application of the SIPAT-J using participants' medical records. The study focused on physical composite outcomes, psychiatric outcomes, and nonadherent behaviors.

RESULTS

The participants were 173 LKT recipients (median age [interquartile range], 51 [38-59]); 67.1% were male and 67.1% were employed. The median (interquartile range) SIPAT scores were SIPAT A [7 (5-9)], SIPAT B [7 (5-9)], SIPAT C [2 (0-4)], SIPAT D [3 (3-4)], and SIPAT total [20 (16-23)]. The physical composite outcome was 25 (14.5%), psychiatric outcome 9 (5.2%), and nonadherent behavior 17 (9.8%). SIPAT C (odds ratio = 1.34, 95% confidence interval = 1.06-1.72, P = 0.02) was significantly associated with the psychiatric outcome. SIPAT B (odds ratio = 1.49, 95% confidence interval = 1.12-1.98, P = 0.01) and SIPAT total (odds ratio = 1.13, 95% confidence interval = 1.03-1.24, P = 0.01) were significantly associated with nonadherent behaviors. There was no significant association between the SIPAT and physical composite outcomes.

CONCLUSION

This study is the first to examine the association between SIPAT and physical and psychiatric outcomes 1 year after LKT, controlling for follow-up periods and factors other than SIPAT. Comprehensive psychosocial assessment before LKT and early identification of factors that may negatively affect transplant success can allow targeted interventions to be implemented and increase the likelihood of favorable recipient outcomes.

Nonadherence to Immunosuppressants Among Transplant Recipients: Emotional Intelligence as a Predictive Factor During COVID-19 Pandemic

Purpose

To evaluate the association between emotional intelligence and fear of COVID-19 on self-reported adherence, based on a cross-sectional design.

Patients and Methods

Transplants recipient of both sexes aged 23-75 years old were evaluated at the Organ Transplant Unit, University Hospital of Catania, Italy. Data were analyzed using frequency, descriptives, Spearman and Pearson correlations, Chi-square goodness of fit test, and linear regression. Self-reported adherence was estimated with the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS). Emotional intelligence and fear of COVID were, respectively, measured with the Emotional Intelligence Scale (EIS) and Multidimensional Assessment of COVID-19 Related Fears Scale (MAC-RF). This was a cross-sectional study of kidney transplant recipients. In reporting this study the authors followed the STROBE guidelines.

Results

A correlation was found between EIS and MAC and between EIS and adherence but there was no correlation between MAC and adherence. A linear regression model was also conducted using a stepwise method, which indicated that EIS was a significant predictor of adherence (p <0.05).

Conclusion

This study was found that EIS is a predictor of adherence to treatment in transplant patients. Fear of COVID, while positively correlated to EIS, is not correlated to the adherence's outcome, possibly due to the proper follow-up performed to the patients. Indeed, according to these results, we suggest to provide good follow-ups with recipients, with interviews also based on self-regulation and awareness.

Efficacy and safety of once-daily prolonged-release tacrolimus versus twice-daily tacrolimus in kidney transplant recipients: A meta-analysis and trial sequential analysis

BACKGROUND

Kidney transplantation is the most important treatment for end-stage renal disease. Immunosuppressive therapies can prevent acute rejection for kidney transplant recipients. Tacrolimus is usually administered to prevent graft rejection after transplantation. Previous studies have indicated that once-daily tacrolimus may improve medication adherence. Therefore, this meta-analysis aimed to compare clinical outcomes between once-daily and twice-daily tacrolimus in de novo renal transplant patients.

METHODS

Eligible studies were identified from the Cochrane Library Database, PubMed, and Embase until July 2022. Those randomized controlled trials (RCTs) evaluating once-daily versus twice-daily tacrolimus formulations in de novo renal transplantation were included. A summary risk ratio (RR) and standardized mean difference (SMD) with the 95% confidence interval (CI) were estimated using a random-effects model.

RESULTS

In total, nine RCTs were included. There were no differences in biopsy-confirmed acute rejection rates between patients with once-daily and those with twice-daily tacrolimus (RR, 0.91; 95% CI, 0.73-1.13) in 12 months. Regarding renal function, there was no significant difference between the once-daily and twice-daily tacrolimus groups (SMD, -0.03; 95% CI, -0.12 to 0.07). In addition, the risk of graft failure, death, and adverse events in the first year was similar for the once-daily and twice-daily tacrolimus groups.

CONCLUSION

Our major findings suggest that de novo renal transplantation recipients receiving once-daily tacrolimus immediately after transplantation have comparable efficacy and safety with those recipients who received twice-daily tacrolimus. Therefore, once-daily tacrolimus medication can be an alternative for de novo renal transplantation recipients.

Characterization of the stanford integrated psychosocial assessment for transplant for heart, liver, and kidney transplant candidates in Japan

BACKGROUND

The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive psychosocial assessment proven useful for predicting the outcomes of organ transplantation that is expected to be useful in Japan. However, the characteristics of organ-specific SIPAT scores for organ transplant recipient candidates in Japan are unclear and, to date, the SIPAT has not been properly utilized in clinical practice. The purpose of this study was to present basic data that can be used to establish the relation between SIPAT scores and post-transplantation psychosocial outcomes as well as organ-specific outcomes.

METHODS

This study included 167 transplant recipient candidates (25 heart, 71 liver, and 71 kidney) who completed a semi-structured interview based on the Japanese version of SIPAT (SIPAT-J) prior to transplantation. The differences between organs in terms of SIPAT scores and differences in SIPAT scores based on demographic data were comparatively analyzed.

RESULTS

The total SIPAT scores were higher for liver recipient candidates than for heart recipient candidates (P = .019). Regarding the subscales, SIPAT B (social support system) scores were higher for liver and kidney recipient candidates than for heart recipient candidates (P = .021), whereas SIPAT C (psychological stability and psychopathology) scores were higher for liver recipient candidates than for kidney recipient candidates (P = .002). Recipient candidates with a history of psychiatric treatment and those who were unemployed had higher SIPAT scores, regardless of the transplant organ, than recipient candidates without a history of psychiatric treatment and those who were employed (P < .001, P = .016, respectively).

CONCLUSIONS

There were notable differences in the total SIPAT-J and subscale scores among the liver, heart, and kidney recipient candidates. Each organ was associated with specific psychosocial issues that should be addressed before transplantation. Interventions such as information provision and patient education based on SIPAT assessment results for each organ may improve recipient post-transplant outcomes.

Prevalence and Patient-Level Correlates of Intentional Non-Adherence to Immunosuppressive Medication After Heart-Transplantation-Findings From the International BRIGHT Study

After heart transplantation (HTx), non-adherence to immunosuppressants (IS) is associated with poor outcomes; however, intentional non-adherence (INA) is poorly understood regarding its international variability in prevalence, contributing factors and impact on outcomes. We investigated (1) the prevalence and international variability of INA, (2) patient-level correlates of INA, and (3) relation of INA with clinical outcomes. Secondary analysis of data from the BRIGHT study-an international multi-center, cross-sectional survey examining multi-level factors of adherence in 1,397 adult HTx recipients. INA during the implementation phase, i.e., drug holiday and dose alteration, was measured using the Basel Assessment of Adherence to Immunosuppressive Medications Scale© (BAASIS©). Descriptive and inferential analysis was performed with data retrieved through patient interview, patient self-report and in clinical records. INA prevalence was 3.3% (n = 46/1,397)-drug holidays: 1.7% (n = 24); dose alteration: 1.4% (n = 20); both: 0.1% (n = 2). University-level education (OR = 2.46, CI = 1.04-5.83), insurance not covering IS costs (OR = 2.21, CI = 1.01-4.87) and barriers (OR = 4.90, CI = 2.73-8.80) were significantly associated with INA; however, clinical outcomes were not. Compared to other single-center studies, this sample's INA prevalence was low. More than accessibility or financial concerns, our analyses identified patient-level barriers as INA drivers. Addressing patients' IS-related barriers, should decrease INA.

Immunosuppressant Adherence Factors Differentiating Compliant and Non-Compliant Kidney Transplant Recipients

The purpose of this study is to find out the psychological factor characteristic of non-adherence patients. The study population comprised kidney transplant recipients aged between 18 and 82 years at least 3 months post-transplant who voluntarily agreed to answer a couple of fully anonymous questionnaires that questions pertaining to basic data, type of immunosuppressive drugs taken, and standardized questionnaires. Participants were recruited using direct routine, free-of-charge visits to specialist doctors in transplant clinics. There was no significant difference in the percentage of men and women in both adherence and non-adherence groups. Non-adherence patients were significantly younger compared to adherence patients. There was also a significant difference in the patient's level of education. Adherence patients were better educated. No significant differences in criteria such as place of residence, having children or a partner, or way of living were observed. However, the emotion scale correlated negatively with the level of life orientation in both groups, but the level of the emotions scale and distractions subscale was negatively correlated with the level of self-esteem only for the adherence group. In future research, it would be worthwhile to focus on lifestyle and health-promoting behaviors in juxtaposition with the propensity for adherence.

Medication Adherence among Allogeneic Haematopoietic Stem Cell Transplant Recipients: A Systematic Review

Recipients of a haematopoietic stem cell transplantation (HSCT) may experience issues in medication adherence (MA) when discharged. The primary aim of this review was to describe the oral MA prevalence and the tools used to evaluate it among these patients; the secondary aims were to summarise factors affecting medication non-adherence (MNA), interventions promoting MA, and outcomes of MNA. A systematic review (PROSPERO no. CRD42022315298) was performed by searching the Cumulative Index of Nursing and Allied Health (CINAHL), Cochrane Library, Excerpta Medica dataBASE (EMBASE), PsycINFO, PubMed and Scopus databases, and grey literature up to May 2022 by including (a) adult recipients of allogeneic HSCT, taking oral medications up to 4 years after HSCT; (b) primary studies published in any year and written in any language; (c) with an experimental, quasi-experimental, observational, correlational, and cross-sectional design; and (d) with a low risk of bias. We provide a qualitative narrative synthesis of the extracted data. We included 14 studies with 1049 patients. The median prevalence of MA was 61.8% and it has not decreased over time (immunosuppressors 61.5% [range 31.3-88.8%] and non-immunosuppressors 65.2% [range 48-100%]). Subjective measures of MA have been used most frequently (78.6%) to date. Factors affecting MNA are younger age, higher psychosocial risk, distress, daily immunosuppressors, decreased concomitant therapies, and experiencing more side effects. Four studies reported findings about interventions, all led by pharmacists, with positive effects on MA. Two studies showed an association between MNA and chronic graft-versus-host disease. The variability in adherence rates suggests that the issues are relevant and should be carefully considered in daily practice. MNA has a multifactorial nature and thus requires multidisciplinary care models.

Utility of patient information leaflet and perceived impact of its use on medication adherence

BACKGROUND

Although patients frequently use patient information leaflets (PILs) to obtain information about medicine, their confidence in using it may be diminished after reading it. This study aimed to assess the public perception of PIL's quality and the perceived impact of its use on medication adherence.

METHODS

A community-based cross-sectional study of 1,138 adult individuals in Saudi Arabia, April-May 2020, was conducted via Survey Monkey using an anonymous validated e-questionnaire. Data were collected on personal characteristics, PIL readership and preferences, perception towards PIL quality and impact of its use on taking medication, and reasons for not reading PIL. In addition, logistic regression analysis was performed to identify the significant predictors of reading PIL. Significance was considered at p < 0.05.

RESULTS

Nearly all participants (91.1%) reported reading PIL. The more read PIL's sections were directions of use (52.7%) and side effects (30.3%). Female gender (OR = 5.64, 95%CI: 3.53,9.02), age over 40 years (OR = 2.80, 95%CI: 1.69,4.64), and secondary education or more (OR = 1.74, 95%CI: 1.06,2.85) were the significant predictors of reading PIL. The majority of PIL readers reported their preference for verbal information (65.8%), hard copy presentation (77%), adding graphics (71.1%), and concise content of PIL (68.8%). In addition, most participants reported PIL always/usually adds to their knowledge of medicines (70.6%) and said that PIL reading positively impacted their medication adherence (64.9%). For only 8.8%, PIL reading negatively impacted their adherence, primarily because of reading information on medicine's side effects and complications (74.4%). More than one-half of participants perceived the PIL quality as good/excellent in terms of; font size (51.3%), language comprehensiveness (64.9%), paper quality (68.0%), and general appearance (64.9%). Getting sufficient information from doctors and pharmacists was the main reason for not reading the PIL (59.2%). Most participants (92.5%) agreed on standardizing how information is displayed in the PIL among all PILs of all companies.

CONCLUSION

PIL is read by nearly all the study sample, especially females, older, and educated subjects. It was perceived as beneficial in upgrading medication adherence. Effective designing of PILs should focus on patients' literacy level and age. Standardization of the PIL structure in all pharmaceutical companies is recommended.

Can pharmacotherapeutic follow-up after allogeneic hematopoietic stem cell transplantation improve medication compliance?

BACKGROUND

Allogeneic Hematopoietic Stem Cell Transplantation (allo-HSCT) is currently one of the most effective therapies in onco-hematology. For the treatment of the disease and prevention of such complications, a complex pharmacotherapeutic regimen is employed. Non-compliance is prevalent among adolescents and young adults with chronic hematological diseases, being reported by up to 50% of the patients.

OBJECTIVE

To evaluate the results of pharmacotherapeutic follow-up on medication compliance and on the knowledge about pharmacotherapy of patients who underwent allo-HSCT.

METHODS

A single-arm, open-label and non-randomized intervention study developed in an allo-HSCT outpatient clinic. The participants attended pharmaceutical consultations and had their knowledge about pharmacotherapy and medication compliance measured by MedTake and Brief Medication Questionnaire (BMQ), respectively.

RESULTS

A total of 27 patients attended pharmaceutical consultations (4.81 consultations/patient; SD = 1.80). There was an improvement in medication compliance and in knowledge between the first and last consultations (p < 0.05). In the final consultation, 70.37% of the patients showed compliance, with a knowledge rate of 98.35% (SD = 3.63). Non-compliant individuals presented a greater tendency to hospital readmissions. There was no relationship between medication compliance and sociodemographic variables, graft-versus-host disease, and knowledge about pharmacotherapy.

CONCLUSIONS

Pharmacotherapeutic follow-up contributed to improving medication compliance. Knowledge about pharmacotherapy alone does not translate into behaviors, which corroborates the complexity of the biopsychosocial factors associated with medication compliance.

The Association between Psychosocial and Age-Related Factors with Adherence to Immunosuppressive Therapies after Renal Transplantation

Renal transplantation (RT) is the optimal renal replacement treatment approach in terms of patient survival and high quality of life. Proper adherence to medication is essential in order to prolong graft life and patient survival. This study aimed to investigate the effects of psychosocial factors and age-related declines on adherence in kidney transplant recipients. Methods: This was a cross-sectional study of kidney transplant recipients, based on regression analysis. Patient adherence was assessed with the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS). Psychosocial and age-related variables were measured with the World Health Organization’s quality of life questionnaire (WHOQoL-BREF), the Mini-Mental State Examination (MMSE), the Hospital Anxiety and Depression Scale (HADS), the Acceptance of Illness Scale (AIS), and the Tilburg Frailty Indicator (TFI). Results: A simple linear regression model indicated that the significant predictors of self-reported adherence (p < 0.05) were age, time since transplant, and anxiety and cognitive functions. For problems with implementing immunosuppressive medication, logistic regression models showed that gender, age, retirement status, hypercholesterolemia, and cognitive impairment were the most significant predictors (p < 0.05). However, after controlling for other predictors in the multiple regression models, anxiety and cognitive ability no longer predicted treatment adherence to immunosuppressive medication. Conclusions: Renal transplantation is the most effective therapy in chronic renal failure patients. Proper adherence to immunosuppressive therapy is critical to prolonging graft and person survival. Our study shows that occupational status more significantly influences adherence to the implementation of treatment in kidney transplant recipients.

Adherence to Immunosuppressive Therapies after Kidney Transplantation from a Biopsychosocial Perspective: A Cross-Sectional Study

Kidney transplantation (KT) is the best method for kidney replacement therapy (KRT) because of patient survival rates and quality of life (QoL). Nowadays, the main cause of graft loss is antibody-mediated rejection. The treatment of humoral injury is difficult with uncertain results and still not firmly established. Therefore, appropriate adherence is crucial to prolong graft and patient survival. This study aims to evaluate the association of transplant patients’ acceptance of illness, symptoms of anxiety and depression, frailty, and QoL with medication adherence in KT recipients. A total of 210 patients after KT completed the surveys. The instruments were distributed during patients’ admission at the clinic by a qualified nurse, who assisted the patients’ in completing the questionnaires. A cross-sectional study of KT recipients 9.45 ± 7.26 years after KT was performed. Patient adherence with medications was assessed using the Adherence to Refills and Medications Scale (ARMS). Explanatory variables were examined with validated instruments, such as the World Health Organization Quality of Life (WHOQoL-BREF) questionnaire, The Mini-Mental State Examination (MMSE), the Acceptance of Illness Scale (AIS), the Hospital Anxiety and Depression Scale (HADS), and the Tilburg Frailty Indicator (TFI) scale, respectively. Simple linear and multiple regression analyses demonstrated the positive correlation between acceptance of illness and adherence to immunosuppressive medications in a patient sample of KT recipients. The other important factor facilitating adherence to medications was linked with physical and environmental dimensions. On the other hand, frail kidney transplant patients were more likely to be non-adherent. In conclusion, identifying contributors to better medication adherence in immunosuppressive therapy is crucial in preventing transplant rejection or graft loss. In the kidney transplant population, the acceptance of illness, selected dimensions of QoL, and demographic variables associated with rural living and vocational education favored adherence behaviors.

Integrated Care of Alcohol-Related Liver Disease

BACKGROUND/AIMS

Alcohol-related liver disease (ALD) is the medical manifestation of alcohol use disorder, a prevalent psychiatric condition. Acute and chronic manifestations of ALD have risen in recent years especially in young people and ALD is now a leading indication of liver transplantation (LT) worldwide. Such alarming trends raise urgent and unanswered questions about how medical and psychiatric care can be sustainably integrated to better manage ALD patients before and after LT.

METHODS

Critical evaluation of the interprofessional implications of broad and multifaceted ALD pathophysiology, general principles of and barriers to interprofessional teamwork and care integration, and measures that clinicians and institutions can implement for improved and integrated ALD care.

RESULTS

The breadth of ALD pathophysiology, and its numerous medical and psychiatric comorbidities, ensures that no single medical or psychiatric discipline is adequately trained and equipped to manage the disease alone.

CONCLUSIONS

Early models of feasible ALD care integration have emerged in recent years but much more work is needed to develop and study them. The future of ALD care is an integrated approach led jointly by interprofessional medical and psychiatric clinicians.

Involvement in Health Behavior After Heart Transplantation: The Role of Personal Resources and Health Status. Single-Center Observational Study

Introduction: Heart transplantation affects all spheres of the patients’ functioning - their physical well-being and coping with everyday situations, as well as their identity and social functioning. Its long-term effects depend on the effective cooperation with the transplant team. Post-transplant patients are expected to be committed to adherence to recommendations. Patients’ subjective characteristics could increase the risk of difficulties during treatment or might have a protective effect. The major aim of the study was to evaluate the level of engagement in health behavior in heart transplant recipients in relation to their personal resources, such as personality traits, and their health status.

Material and Method: The observational ex post facto model was proposed. Participants completed a set of psychological questionnaires. In the study, there were used questionnaires regarding health behavior (HBI), personality traits (NEO-FFI), health locus of control (MHLC), self-efficacy (GSES) and health status (GHQ-28). The group included in the analyses consisted of 107 heart transplant patients. They ranged in age from 19 to 75 years; 10.3% of them were women.

Results: According to norms, 71% patients reported high level of engagement in health behavior. There were significant differences in the level of dietary habits and other types of health behaviors. The best predictors of overall health behavior were conscientiousness (β = 0.20, p < 0.05) and health locus of control (Powerful Others) (β = 0.25, p < 0.05). The prophylaxis behavior was related significantly to the level of conscientiousness (p < 0.05) and health locus of control (Internal and Powerful Others) (p < 0.05; p < 0.01). The level of positive mental attitude was related significantly to agreeableness (p < 0.05), health locus of control (Powerful Others) (p < 0.01), and self-efficacy (p < 0.01). Everyday healthy practices were related significantly to openness to experience (p < 0.01) and health locus of control (all categories: Internal, Powerful Others and Chance) (p < 0.05; p < 0.01; p < 0.05, respectively).

Conclusion: Majority of heart transplant patients is engaged in high level of health behavior. Among the various forms of health-relevant habits, heart transplant patients adhere significantly less frequently to a healthy diet. Among examined resources, the best predictors of caring about health are generalized self-efficacy and age at the time of HTx.

Psychosocial Assessment of Transplant Candidates: Inter-rater Reliability and Concurrent Validity of the Japanese Version of the Stanford Integrated Psychosocial Assessment for Transplantation

BACKGROUND

The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) is a comprehensive instrument developed to provide a standardized, objective, and evidence-based psychosocial evaluation of the main pretransplant psychosocial risk factors that may influence transplant outcomes.

OBJECTIVE

Because established assessment procedures or standardized tools designed to perform pre-solid organ transplant psychosocial evaluation are currently unavailable in Japan, the present study aimed to develop and preliminarily validate the Japanese version of the SIPAT.

METHODS

First, the Japanese version of the SIPAT was developed using standard forward-back-translation procedures. Then, the Japanese versions of the SIPAT and the Japanese version of Psychosocial Assessment of Candidates for Transplant were retrospectively and blindly applied to 107 transplant cases by 4 independent raters.

RESULTS

The interrater reliability of the scores obtained with the Japanese version of the SIPAT was excellent (Pearson's correlation coefficient = 0.86). The concurrent validity of the SIPAT to the Psychosocial Assessment of Candidates for Transplant for each examiner was substantial (Spearman's rank correlation coefficient = -0.66).

CONCLUSION

These findings suggest that the Japanese version of the SIPAT is a promising and reliable instrument. Further research is required to test the predictive validity of the Japanese version of the SIPAT.

Hospice care for end stage liver disease in the United States

INTRODUCTION

Patients with end-stage liver disease (ESLD) have impaired physical, psychological, and social functions, which can diminish patient quality of life, burden family caregivers, and increase health-care utilization. For those with a life expectancy of less than six months, these impairments and their downstream effects can be addressed effectively through high-quality hospice care, delivered by multidisciplinary teams and focused on the physical, emotional, social, and spiritual wellbeing of patients and caregivers, with a goal of improving quality of life.

AREAS COVERED

In this review, we examine the evidence supporting hospice for ESLD, we compare this evidence to that supporting hospice more broadly, and we identify potential criteria that may be useful in determining hospice appropriateness.

EXPERT OPINION

Despite the potential for hospice to improve care for those at the end of life, it is underutilized for patients with ESLD. Increasing the appropriate utilization of hospice for ESLD requires a better understanding of patient eligibility, which can be based on predictors of high short-term mortality and liver transplant ineligibility. Such hospice criteria should be data-driven and should accommodate the uncertainty faced by patients and physicians.

Medical adherence and liver transplantation: a brief review

Liver transplantation remains the only feasible long-term treatment option for patients with end-stage liver disease. Despite significant medical and surgical advances over the decades, liver transplantation remains a complex undertaking with the need for indefinite immunosuppression and avoidance of patient behaviours that may jeopardize the allograft. Adherence (formerly called "compliance") to medical recommendations in terms of anti-rejection medications and-in the case of alcoholic liver disease, abstinence-is considered a key cornerstone to long-term allograft and patient survival. Not surprisingly, a history of habitual non-adherence is considered a contraindication to liver transplantation, especially re-transplantation. It is often assumed that non-adherence policies are "self-evidential" based on "common sense" and "expert opinion." In fact, non-adherence and its negative effects have been well studied in medicine, including in solid organ transplantation. In this review, we present the evidence that non-adherence to medical advice is clearly associated with worse medical outcomes, supporting the concept that efforts to support patient adherence post-transplant need to be optimized at all times.

An E-Learning Program Improves Patients' Knowledge After Lung Transplantation

Background: Adherence to immunosuppressive medicine in lung transplant recipients is associated with improved long-term survival. Patient education and support from health care providers are key components. We investigated e-learning as a tool to improve lung transplant recipients' knowledge of post-transplant care such as hygiene, self-monitoring, travel precautions, vaccinations, and the importance of adherence to medication. Objective: To compare the effect of e-learning and conventional patient education with respect to level of knowledge and drug adherence. A single-center open randomized controlled trial design was used. Methods: Lung transplant recipients were randomized to an e-learning program or standard care. One month before a scheduled follow-up visit, the intervention group received a link by e-mail to a 15-min e-learning program. At the follow-up visit, all lung transplant recipients completed two drug adherence questionnaires (Basel Assessment of Adherence with Immunosuppressive medication Scales [BAASIS] and Transplant Adherence Questionnaire [TAQ]) and a questionnaire testing their knowledge of post-transplant care. Results: Fifty lung transplant recipients were randomized with 24 recipients in each group completing the study. Recipient adherence measured by BAASIS showed a tendency toward improved drug adherence in the intervention group compared with the control group (71% vs. 55%, p = 0.23). TAQ showed no difference between the two groups (p = 1.0). Recipients in the intervention group had a significantly higher number of correct answers to questions about transplant-friendly lifestyle (median 11 vs. 10, p = 0.02). Conclusion: A 15-min e-learning program is a simple and effective tool to improve lung transplant recipients' knowledge of post-transplant care.

Seven Shades of Black Thoughts: COVID-19 and Its Psychological Consequences on Cancer Patients

An outbreak of novel coronavirus disease (COVID-19) that started in China at the end of 2019 has rapidly spread all over the world. COVID-19 is plaguing people not only physically but also psychologically, and cancer patients are particularly exposed to this emotional threat. Herein, we describe the psychological threats posed by COVID-19 to cancer patients. Our analysis is based on the concerns of our patients during our daily clinical interactions in both outpatient and inpatient settings. We have summarized the patients' psychological issues: logistic overload, loneliness, fear, oxymoronic thoughts, helplessness, frustration, and emotional siege. We describe these psychological threats, provide clinical context for them, and offer practical suggestions for managing them, for the benefit of patients, their caregivers, and clinicians. Our hope is that, by sharing our clinical experience, we can help other oncologists increase their awareness of the psychological impact of the pandemic on cancer patients and implement solutions. Managing these challenges now should translate into improved standards of care when this infective storm is over. Paradoxically, COVID-19 could be an opportunity to learn how to better manage cancer care.

A Review of the Prevalence of Illicit Substance Use in Solid-Organ Transplant Candidates and the Effects of Illicit Substance Use on Solid-Organ Transplant Treatment Outcomes

Solid-organ transplantation is one of the significant advances in the medical field that have improved the quality of life and survival rates of numerous patients with end-organ dysfunction. Substance use is a common condition of individuals who are in need of solid-organ transplantation. The implications of substance use on solid-organ transplants are gaining increasing attention over the past decade. The current review seeks to explore the prevalence rate of illicit substance use among those who receive solid-organ transplantation (pre and post-transplant) and whether illicit substance use before solid-organ transplantation affects the outcome of solid-organ transplants. We searched the Medline database for all the articles available in English on the prevalence of substance use in the context of solid-organ transplant and the effect on outcome measures. We found 21 relevant articles. It appears that substance use is fairly common among solid-organ transplant candidates, with cannabis being the most common substance of abuse. A heterogeneous sample precludes the drawing of a clear-cut conclusion. But it appears that substance use may affect various outcomes of solid-organ transplants. The existing literature may not be sufficient to adequately assess the risk but limited evidence indicates that illicit substance use, particularly cannabis use, may not affect the overall survival following a solid-organ transplant.

Adults transplanted as children as retransplant candidates: Analysis of outcomes support optimism in a population mislabeled as high risk

Adult liver transplant programs have heretofore been hesitant to perform liver retransplantation in adult patients who underwent primary liver transplantation as a child (P_A). Areas of concern include: (a) potential disruption in care when transferring from a pediatric to an adult transplant center; (b) generally inferior outcomes of retransplantation; (c) reputation of young adults for non-adherence to post-transplant regimen; and (d) potential higher work effort for equivalent outcomes. To examine these concerns, we reviewed data on all US liver adult retransplants from 10/01/1987 to 9/30/2017. We propensity matched the P_A patients to patients who received both primary and retransplantation as adults (A_A), with ≥550 days between transplants. A mixed Cox proportional hazards model with program size and time period of transplantation as random variables revealed that retransplantation of P_A patients produced no significantly different graft survival or patient survival rates than retransplantation of the matched A_A patients. Therefore, inferior rates of liver retransplantation in these patients and concerns about continuity of care in changing transplant programs are not as believed in the wider liver transplant community. In conclusion, liver transplant centers should be optimistic about retransplanting adults who received their primary transplants as children.

Determinants of Medication Adherence in Liver Transplant Recipients

BACKGROUND

The aim of this study was to study the determinants of nonadherence to immunosuppressant drugs in liver transplant (LT) recipients using personalised interview and questionnaire methods.

METHODS

The study was conducted on adult LT recipients (deceased donor liver transplant [DDLT] and living donor liver transplant [LDLT]) from the Indian subcontinent, at post-LT clinic visit between July and December 2016. Recipient details included baseline demography, comorbidity, psychological status, details of addiction, indication and type of transplant. Details on financial support for transplantation, admissions for rejection, infection and posttransplant complications were obtained from the hospital records. An adherence questionnaire was completed by direct interview and using a questionnaire.

RESULTS

Sixty-seven LT recipients (56 males, median age 48.17 years) constituted the study group. Overall, 11 patients (16.47%) were nonadherent to treatment. LDLT recipients were more adherent than DDLT recipients. Nonadherent recipients were believers in alternative systems of medicine. Medication-related factors such as improper dosing, meagre drug knowledge difficulty in remembering drug dose and timings and economic constraints in continuing medical treatment were statistically significant in nonadherent recipients. Although variation in the tacrolimus levels were significantly more common in the nonadherent group, acute cellular rejection and infection were not statistically different.

CONCLUSIONS

The prevalence of nonadherence was 16.5%. Determinants of nonadherence were DDLT, belief in alternative medications, high regimen complexity, poor knowledge about medications and cost issues with long-term medications.

A Multicenter, Prospective, Observational Study of Conversion from Twice-Daily Immediate-Release to Once-Daily Prolonged-Release Tacrolimus in Liver Transplant Recipients in France: The COBALT Study

Background

In adult liver transplant patients, the use of prolonged-release tacrolimus may have treatment adherence benefits over the immediate-release formulation. The aim of this study was to characterise real-world practice data on conversion of liver transplant recipients from immediate- to prolonged-release tacrolimus in France.

Material/Methods

A prospective, observational study (NCT02143479) was conducted in 18 transplant centers in France between June 2014 and March 2016. Liver transplant recipients (n=398) included patients who changed from immediate-release to prolonged-release tacrolimus within the first three months (early conversion group) (n=205) or between three and 12 months after transplantation (late conversion group) (n=184). Clinical data were collected at an initial baseline outpatient visit and six-month and 12-month follow-up visits. Endpoints included the dose conversion ratio from immediate-release to prolonged-release tacrolimus, number of and reasons for additional visits due to conversion, safety, and tolerability.

Results

Baseline clinical and demographic characteristics were similar between the two cohorts. The mean ±SD ratio of conversion of tacrolimus dose was 1.04±0.28; 1.01±0.28 (early) and 1.08±0.28 (late) (p=0.0247). The mean ±SD time from conversion to the first tacrolimus trough blood concentration was 30.8±42.8 days; 24.8±45.4 days (early) and 37.5±38.7 days (late). Only one patient required an additional visit due to conversion. Reasons for conversion included the physician’s preference (56.3%), center practice (38.6%), and the dosing frequency (36.0%). Conversion was associated with a low rate of graft rejection, and no new safety issues were reported.

Conclusions

Conversion of liver transplant recipients from immediate-release to prolonged-release tacrolimus within three to 12 months of transplantation was easy to manage and associated with favorable clinical outcomes and safety profiles.

Conversion From Immediate-Release Tacrolimus to Prolonged-Release Tacrolimus in Stable Heart Transplant Patients: A Retrospective Study

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.

Gender and age differences of compliance in liver transplant recipients

Introduction: The aim of the paper was to evaluate the compliance in patients who have undergone orthotopic liver transplantation (OLT).

Materials and methods: A voluntary anonymous survey was conducted among liver transplant recipients. The control group included patients with chronic non-infectious diseases requiring persistent treatment. The questionnaire “The level of Compliance” designed by R.V. Kadyrov was used.

Results and discussion: The following compliance levels were identified in liver transplant recipients: the general level – 95.8±9.4; the social level – 30.4±4.2; the emotional level – 33.3±3.7; the behavioral level – 32.0±3.8. The compliance levels of the control group were significantly lower compared to the values of group 1, respectively: the general level – by 9%, the social level – by 5.6%, the emotional level – by 10.3% and the behavioral level – by 11.9%. The general compliance level of the recipients under 50 years old reached 93.5±6.8; the social compliance level – 28.9±3.9; the emotional compliance level – 33.6±2.9 and the behavioral compliance level –31.0±2.2.

Conclusions: Liver transplant patients have higher levels of general, behavioral and emotional compliance compared to patients with chronic diseases. Neither gender nor age differences were identified in any types of compliance.

Pattern and associated factors of adherence to immunosuppressive medications in kidney transplant recipients at a referral center in Iran

Purpose: Ever increasing number of patients who receive kidney transplantation as a therapeutic option, approaches to increase graft survival as well as to identify factors that reduce the treatment outcomes should be taken into account. One of the heightened concerns after transplantation is non-adherence to immunosuppressive medications, which increases the risk of kidney failure or even rejection. The aim of this study was to evaluate factors associated with immunosuppressant medications adherence in kidney transplant recipients. Patients and methods: Data were collected from 100 eligible kidney transplant patients referring to Shiraz Motahhari clinic and a private office of an attending nephrologist during 18 months. Adherence to immunosuppressive medications was assessed by Basel assessment of adherence to immunosuppressive medication scale at 2 time points. Results: According to the findings, 55% of patients did not adhere to their post-transplantation immunosuppressive medications. The rate of adherence to immunosuppressive medications was not either statistically or clinically significant between time points zero and six months. None of the investigated factors including demographic, clinical and social-economical-cultural factors were significantly associated with patients' adherence to immunosuppressive regimen. Furthermore, there was no statistically significant association between immunosuppressive medication adherence and acute kidney rejection. Conclusion: The rate of non-adherence to immunosuppressive medications was high. These data can be exploited by both physicians and policymakers to improve the rate of adherence to immunosuppressive medications amongst kidney transplant recipients.

The Portuguese Version of the Immunosuppressant Therapy Adherence Scale (ITAS) among Liver Transplant Recipient Patients: Translation and Psychometric Properties

INTRODUCTION AND AIM

Transplant recipients are chronically ill patients who rely on medical treatment throughout life to achieve positive results. Despite that, medication nonadherence after liver transplantation is extremely common. The self-report, one of several methods for measuring adherence, is easy to apply and low cost. Thus, this study aims to translate and validate the Immunosuppressant Therapy Adherence Instrument (ITAS) in Brazilian Portuguese for liver transplant recipients.

MATERIAL AND METHODS

A total of 139 liver transplant recipients were selected from a general hospital, who were assessed by using the Portuguese version of ITAS. The scale was translated based on the model proposed by Wild, et al. and its psychometric properties were assessed.

RESULTS

The average Cronbach's α coefficient was 0.830. ITAS and Basel Assessment of Adherence with Immunosuppressive Medications Scale (BAASIS) presented significant correlation, with a Spearman's ρ coefficient = 0.300 (S = 309,580; p < 0.001). The area under the receiver operating characteristics (ROC) curve was 0.638 (95% CI: 0.557 - 0.715). Factor analysis results indicated that the carelessness factor model was the optimal model, and the factor "feeling worse" was the lowest.

CONCLUSION

The Portuguese version of ITAS has adequate psychometric properties to measure adherence to immunosuppressant therapy.

Adherence to and Acceptance of Once-Daily Tacrolimus After Kidney and Liver Transplant: Results From OSIRIS, a French Observational Study

BACKGROUND

Adherence to immunosuppressive treatments is a major concern in transplanted patients.

METHODS

This 6-month French observational, longitudinal, prospective study aimed to assess patient adherence to and acceptance of once-daily tacrolimus (Advagraf) initiation in kidney and liver transplant recipients. Data from 1106 patients initiating once-daily tacrolimus during posttransplant follow-up were analyzed. Adherence and acceptance were assessed using self-administered questionnaires at inclusion and at 3 and 6 months.

RESULTS

Mean age was 52.4 ± 13.2 years, 61.5% were men. For 94.9% of patients, once-daily tacrolimus was prescribed after switching from twice-daily tacrolimus. At inclusion, 20.9% of patients reported good treatment adherence, 72.0% minor nonadherence, and 7.1% were nonadherent. Mean general acceptance score (range, 0-100) was 77.7 (±24.7). At 3 months, adherence was improved in 21.1%, unchanged in 69.2%, and worsened in 9.7% of patients. Mean general acceptance score was 75.4 (±26.5). General acceptance score was improved in 28.0%, unchanged in 39.4%, and worsened in 32.7% of patients. At 6 months, similar changes in adherence and acceptance were observed. Higher general acceptance score at month 3 was significantly associated with better adherence at month 6.

CONCLUSIONS

Conversion to once-daily tacrolimus led to an improved rate of adherence at month 3 in more than 20% of patients and a worsened rate of adherence in less than 10% of patients.

Psychosocial predictors of medication non-adherence in pediatric organ transplantation: A systematic review

Adherence to immunosuppressant medication is critical to health and quality-of-life outcomes for children who have received a solid organ transplant. Research on the psychological and social predictors of medication adherence is essential to the advancement of pretransplant assessments and transplant psychosocial services. Despite the importance of identifying risk factors, the literature remains limited regarding psychosocial predictors of non-adherence. A systematic search was conducted to identify studies of the psychosocial predictors of post-transplant medication non-adherence in pediatric solid organ transplantation. From 1363 studies identified in searches of empirical literature, a final sample consisted of 54 publications representing 49 unique studies. Findings regarding psychosocial predictors were inconsistent with non-adherence associated largely with adolescence, racial/ethnic minority status, and presence of mental health issues. Familial predictors of non-adherence problems included single-parent households, lower socioeconomic status, lower family cohesion, presence of family conflict, and poor family communication. Several studies reported an association between non-adherence and social pressures (eg, peer social interaction, wanting to feel normal) among adolescent transplant recipients. While significant methodological and substantive gaps remain in this body of knowledge, this review synthesizes current evidence for assessment for transplant clinicians and researchers.

A Study on Adherence to Follow-up, Quality of Life, and Associated Factors Among Renal Transplant Recipients in China

BACKGROUND

Adherence to follow-up is vital for the medical surveillance of the postoperative blood concentration, but relatively little research has examined it, and there is less study on relationships between adherence to follow-up and quality of life (QoL). We investigated the status of adherence to follow-up and QoL and associated factors among kidney transplantation recipients in China.

METHODS

A cross-sectional study with the use of a Kidney Transplantation Recipient's Adherence to Follow-Up Questionnaire and a Quality of Life of Kidney Transplantation Recipients Questionnaire was conducted among 250 kidney transplantation recipients in Changsha, China, from January to March in 2015.

RESULTS

The mean score for adherence to follow-up was 54.71 ± 6.46. Time after transplantation was the only factor affecting adherence to follow-up scores (β = -0.210; P < .05). The mean total score for QoL was 140.39 ± 13.56; physical functioning, 23.72 ± 3.33; psychologic functioning, 24.46 ± 4.23; social functioning, 44.43 ± 6.80; treatment, 24.81 ± 2.97; and subjective satisfaction, 21.28 ± 3.15. Multiple linear regression analysis showed that adherence to follow-up, economic level, job status, donor source, and original disease affected with QoL.

CONCLUSIONS

Adherence to follow-up decreases with time after transplantation, and better compliance is associated with better QoL in all areas. Improvements in adherence to follow-up, income and reimbursement, psychologic guidance, and social support may increase QoL of kidney transplantat recipients.

Adherence to Mediterranean and low-fat diets among heart and lung transplant recipients: a randomized feasibility study

BACKGROUND

Heart and lung transplant recipients are at a substantially increased risk of cardiovascular disease (CVD). Since both low-fat and Mediterranean diets can reduce CVD in immunocompetent people at high risk, we assessed adherence among thoracic transplant recipients allocated to one or other of these diets for 12 months.

METHODS

Forty-one transplant recipients (20 heart; 21 lung) randomized to a Mediterranean or a low-fat diet for 12 months received diet-specific education at baseline. Adherence was primarily assessed by questionnaire: 14-point Mediterranean diet (score 0-14) and 9-point low-fat diet (score 0-16) respectively, high scores indicating greater adherence. Median scores at baseline, 6 months, 12 months, and 6-weeks post-intervention were compared by dietary group. We further assessed changes in weight, body mass index (BMI) and serum triglycerides from baseline to 12 months as an additional indicator of adherence.

RESULTS

In those randomized to a Mediterranean diet, median scores increased from 4 (range 1-9) at baseline, to 10 (range 6-14) at 6-months and were maintained at 12 months, and also at 6-weeks post-intervention (median 10, range 6-14). Body weight, BMI and serum triglycerides decreased over the 12-month intervention period (mean weight - 1.8 kg, BMI -0.5 kg/m2, triglycerides - 0.17 mmol/L). In the low-fat diet group, median scores were 11 (range 9-14) at baseline; slightly increased to 12 (range 9-16) at 6 months, and maintained at 12 months and 6 weeks post-intervention (median 12, range 8-15). Mean changes in weight, BMI and triglycerides were - 0.2 kg, 0.0 kg/m2 and - 0.44 mmol/L, respectively.

CONCLUSIONS

Thoracic transplant recipients adhered to Mediterranean and low-fat dietary interventions. The change from baseline eating habits was notable at 6 months; and this change was maintained at 12 months and 6 weeks post-intervention in both Mediterranean diet and low-fat diet groups. Dietary interventions based on comprehensive, well-supported education sessions targeted to both patients and their family members are crucial to success. Such nutritional strategies can help in the management of their substantial CVD risk.

Conversion From Twice-Daily to Once-Daily Tacrolimus in Stable Kidney Graft Recipients

INTRODUCTION

Immunosuppression has a pivotal role in kidney transplantation. The new prolonged-release formulation of tacrolimus was developed to provide a more convenient once-daily dosing to improve patient adherence.

METHODS

We selected 60 stable kidney transplant recipients who underwent tacrolimus conversion in our unit. Conversion was made on a 1 mg:1 mg basis in 66.7% of patients (n = 40) and on a 1 mg:1.1 mg basis in the remaining 33.3% (n = 20). Clinical and analytical data at conversion and postconversion was analyzed retrospectively to evaluate the efficacy and safety of conversion from tacrolimus twice-daily to once-daily formulation.

RESULTS

A significant reduction in tacrolimus blood levels requiring an increase in tacrolimus daily dose was observed postconversion. Postconversion tacrolimus blood level reduction >25% was significantly higher in the conversion group 1 mg:1 mg basis (P = .004). In patients converted 1 mg:1 mg, female sex and higher tacrolimus level at conversion were significant risk factors for a reduction >25% in tacrolimus blood levels after conversion. No significant change was detected between mean glomerular filtration rate at conversion (57 mL/min) and at 3, 6, and 9 months postconversion.

CONCLUSIONS

Once-daily tacrolimus at similar doses to the twice-daily formulation is an efficient and safe treatment option. Conversion made on 1 mg:1.1 mg basis seems advantageous at least in some patients.

A New Quantitative Approach to Assessing Noncompliance With Medical Recommendations in Heart Transplant Recipients

BACKGROUND

Failure of compliance with medical regimen is one of the major risk factors associated with morbidity and mortality in heart transplant (HT) recipients. Nevertheless, to date, there is no specific, gold-standard, comprehensive set of tools for assessing compliance in these patients.

OBJECTIVE

The objective of the present study was to develop a specific instrument for the assessment of noncompliance with medical recommendations in HT recipients.

METHODS

This prospective observational study used a nonprobability sampling method, which was performed from January 2006 to December 2012. All of the patients met clinical criteria for being included on the waiting list for a HT. We designed a scale for measuring the compliance degree at 12 months after heart transplantation. This scale included the most important aspects of the medical regimen, using nine discrete quantitative variables. The total score was described as the patient's Noncompliance Factor (NCF). The results were analysed by mean, ranks, and percentages.

RESULTS

The sample was constituted of 61 participants who underwent surgical HT intervention and completed the 12-month follow-up assessment. The overall incidence of noncompliance was around 30% and only 43.1% of the recipients had an acceptable degree of compliance.

CONCLUSIONS

The overall incidence of noncompliance in HT recipients is high and this can generate worse clinical outcomes. Evaluation by specific screening instruments like the one proposed in the present study can be useful for a systematic detection of this phenomenon.

Preoperative Predictors for Postoperative Problems in Heart Transplantation: Psychiatric and Psychosocial Considerations

The psychiatric and psychosocial evaluation of the heart transplant candidate can identify particular predictors for postoperative problems. These factors, as identified during the comprehensive evaluation phase, provide an assessment of the candidate in context of the proposed transplantation protocol. Previous issues with compliance, substance abuse, and psychosis are clear indictors of postoperative problems. The prolonged waiting list time provides an additional period to evaluate and provide support to patients having a terminal disease who need a heart transplant, and are undergoing prolonged hospitalization. Following transplantation, the patient is faced with additional challenges of a new self-image, multiple concerns, anxiety, and depression. Ultimately, the success of the heart transplantation remains dependent upon the recipient's ability to cope psychologically and comply with the medication regimen. The limited resource of donor hearts and the high emotional and financial cost of heart transplantation lead to an exhaustive effort to select those patients who will benefit from the improved physical health the heart transplant confers.

Nonadherence with Immunosuppressive Drugs: Us Compared with European Kidney Transplant Recipients

Background

System factors increasingly are suggested as important yet understudied correlates of nonadherence.

Objective

To explore the relationship between healthcare system and prevalence of nonadherence with immunosuppressive regimen by studying variation in nonadherence between European and US kidney transplant recipients and as well as nonadherence in European countries.

Methods

We performed a secondary data analysis on data collected in 3 independent cross-sectional studies using comparable methodology including patients from the United States, the Netherlands, Belgium, and Switzerland. Nonadherence was measured using 1 item of the Siegal questionnaire. Patients were categorized as nonadherent if they reported missing a dose of immunosuppression in the last 4 weeks. Analyses were performed by multiple mixed logistic regression, with center as a random effect and clinical and demographical differences between groups as fixed effects.

Results

1563 US and 614 European patients from 3 different countries (Belgium [n=187], the Netherlands [n=85], and Switzerland [n=342]) were included. Prevalence of nonadherence in the United States and Europe was 19.3% and 13.2.%, respectively. This higher nonadherence in US patients was confirmed in a multiple logistic regression analysis (OR=1.78; 95% CI, 1.10–2.89). Nonadherence differed between Belgium (16%) and the Netherlands (14.1%) (OR=0.27; 95% CI, 0.09–0.80) and between Belgium and Switzerland (11.4%; OR=0.17; 95% CI, 0.0–0.42).

Conclusion

This is the first study showing differences in prevalence of nonadherence between European and US patients and among European patients. Further research should aim at unraveling the dynamics explaining these differences.

Conversion of once-daily extended-release tacrolimus is safe in stable liver transplant recipients: A randomized prospective study

Simplifying the therapeutic regimen of liver transplantation (LT) recipients may help prevent acute rejection and graft failure. The present study aimed to evaluate the efficacy and safety of conversion from twice-daily tacrolimus to once-daily extended-release tacrolimus under concurrent mycophenolate mofetil therapy in stable LT recipients. This randomized, prospective, controlled study included 91 patients who underwent LTs with at least 1 year of posttransplant follow-up. Conversion was made on a 1 mg to 1 mg basis. No incidences of biopsy-proven acute rejection, graft failure, or death were reported in either group at 24 weeks. Median serum tacrolimus level of the study group was 20% less than that of the control group at 8 weeks. However, no significant differences regarding biochemical indicators of liver function or serum creatinine levels were observed between the 2 groups. Adverse event (AE) profiles were similar for both groups, with comparable incidences of AEs and serious AEs. No significant differences regarding efficacy or safety were observed between the once-daily tacrolimus and twice-daily tacrolimus groups of stable LT recipients. In conclusion, our study suggests that tacrolimus can be safely converted from a twice-daily regimen to a once-daily regimen in stable LT recipients.

Novel Once-Daily Extended-Release Tacrolimus Versus Twice-Daily Tacrolimus in De Novo Kidney Transplant Recipients: Two-Year Results of Phase 3, Double-Blind, Randomized Trial

BACKGROUND

1-year data from this trial showed the noninferiority of a novel once-daily extended-release tacrolimus (LCPT; Envarsus XR) to immediate-release tacrolimus (IR-Tac) twice daily after kidney transplantation.

STUDY DESIGN

Final 24-month analysis of a 2-armed, parallel-group, randomized, double-blind, double-dummy, multicenter, phase 3 trial.

SETTING & PARTICIPANTS

543 de novo kidney recipients randomly assigned to LCPT (n=268) or IR-Tac (n=275); 507 (93.4%) completed the 24-month study.

INTERVENTION

LCPT tablets once daily at 0.17 mg/kg/d or IR-Tac twice daily at 0.1 mg/kg/d; subsequent doses were adjusted to maintain target trough ranges (first 30 days, 6-11 ng/mL; thereafter, 4-11 ng/mL). The intervention was 24 months; the study was double blinded for the entirety.

OUTCOMES & MEASUREMENTS

Treatment failure (death, transplant failure, biopsy-proven acute rejection, or loss to follow up) within 24 months. Safety end points included adverse events, serious adverse events, new-onset diabetes, kidney function, opportunistic infections, and malignancies. Pharmacokinetic measures included total daily dose (TDD) of study drugs and tacrolimus trough levels.

RESULTS

24-month treatment failure was LCPT, 23.1%; IR-Tac, 27.3% (treatment difference, -4.14% [95% CI, -11.38% to +3.17%], well below the +10% noninferiority criterion defined for the primary 12-month end point). Subgroup analyses showed fewer treatment failures for LCPT versus IR-Tac among black, older, and female recipients. Safety was similar between groups. From month 1, TDD was lower for LCPT; the difference increased over time. At month 24, mean TDD for LCPT was 24% lower than for the IR-Tac group (P<0.001), but troughs were similar (means at 24 months: LCPT, 5.47 ± 0.17 ng/mL; IR-Tac, 5.8 ± 0.30 ng/mL; P=0.4).

LIMITATIONS

Trial participant eligibility criteria may limit the generalizability of results to the global population of de novo kidney transplant recipients.

CONCLUSIONS

Results suggest that once-daily LCPT in de novo kidney transplantation has comparable efficacy and safety profile to that of IR-Tac. Lower TDD reflects LCPT's improved bioavailability and absorption.

The Stanford Integrated Psychosocial Assessment for Transplantation: A Prospective Study of Medical and Psychosocial Outcomes

BACKGROUND

Psychosocial factors may significantly affect post-transplant outcomes. The Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) was developed as an assessment tool to enhance the pre-transplant psychosocial evaluation.

METHODS

We identified heart, lung, liver, or kidney transplant recipients assessed with the SIPAT pre-transplantation and transplanted between June 1, 2008, and July 31, 2011, at our institution. We analyzed prospectively accumulated psychosocial and medical outcomes at 1 year of follow-up.

RESULTS

217 patients were identified and included in the analysis. The primary outcomes of organ failure and mortality occurred in 12 and 21 patients, respectively, and were not significantly associated with the pre-transplant SIPAT scores. On the other hand, SIPAT scores were significantly correlated with the probability of poor medical and psychosocial outcomes (secondary outcomes). In fact, higher SIPAT scores predicted higher rates of rejection episodes (Spearman ρ = 0.15, 95% 95% confidence interval [CI] = 0.02-0.28, p = .023), medical hospitalizations (ρ = 0.29, 95% CI = 0.16-0.41, p < .001), infection rates (p = .020), psychiatric decompensation (p = .005), and support system failure (area under the curve = 0.70, 95% CI = 0.60-0.79, p < .001). The relationship with nonadherence suggested a trend, but no statistical significance was observed (area under the curve = 0.60, 95% CI = 0.50-0.71, p = .058).

CONCLUSIONS

Study outcomes suggest that SIPAT is a promising pre-transplantation assessment tool that helps identify candidate's areas of psychosocial vulnerability and whose scores are associated with both psychosocial and medical outcomes after transplantation.

Novel once-daily extended-release tacrolimus (LCPT) versus twice-daily tacrolimus in de novo kidney transplants: one-year results of Phase III, double-blind, randomized trial

This Phase III randomized trial examined efficacy and safety of a novel once-daily extended-release tacrolimus formulation (LCP-Tacro [LCPT]) versus twice-daily tacrolimus in de novo kidney transplantation. Primary efficacy end point was proportion of patients with treatment failure (death, graft failure, biopsy-proven acute rejection or lost to follow-up) within 12 months. Starting doses were, LCPT: 0.17 mg/kg/day and tacrolimus twice-daily: 0.1 mg/kg/day; 543 patients were randomized, LCPT: n = 268; tacrolimus twice-daily: n = 275. At 12 months treatment failure was LCPT: 18.3% and tacrolimus twice-daily: 19.6%; the upper 95% CI of the treatment difference was +5.27%, below the predefined +10% noninferiority criteria. There were no significant differences in the incidence of individual efficacy events or adverse events. Target tacrolimus trough levels were more rapidly achieved in the LCPT group. Following initial dose, 36.6% of patients in the LCPT group had rapidly attained trough levels within 6-11 ng/mL versus 18.5% of tacrolimus twice-daily patients; majority of tacrolimus twice-daily patients (74.7%) had troughs <6 ng/mL compared with 33.5% in the LCPT group. Overall, cumulative study dose was 14% lower for LCPT. Results suggest that use of once-daily LCPT in de novo kidney transplantation is efficacious and safe. Lower LCPT dose reflects the improved absorption provided by the novel formulation.

Viviendo con trasplante renal, sin protección social en salud: ¿Qué dicen los enfermos sobre las dificultades económicas que enfrentan y sus efectos?

El trasplante es el mejor tratamiento para la insuficiencia renal, de acuerdo con la biomedicina; sin embargo, es una tecnología cara. Este artículo examina las dificultades económicas y sus efectos en personas con trasplante renal, pero sin protección social en salud. Para el estudio se desarrolló una investigación cualitativa en México. Participaron 21 pacientes trasplantados; se aplicaron entrevistas semiestructuradas, y se realizó un análisis de contenido. Los resultados muestran que las personas enfermas enfrentan dificultades económicas, debido a los costes de las terapias renales, particularmente, de las medicinas. Todo ello tiene efectos negativos: las personas con pocos recursos dejan el tratamiento con medicamentos, abandonan el protocolo, no asisten a las consultas médicas y disminuyen los gastos domésticos, incluyendo el de alimentación; además de suponer una merma en los ingresos familiares. En conclusión, el trasplante renal empobrece a las personas enfermas sin protección social en salud; es urgente la implementación de un sistema de protección social para esta población.
