Long-Term Follow-up of a Randomized Controlled Trial Evaluating a Mobile Health Intervention for Self-Management in Lung Transplant Recipients.

Mobile health interventions may help transplant recipients follow their complex medical regimens. Pocket Personal Assistant for Tracking Health (Pocket PATH) is one such intervention tailored for lung transplant recipients. A randomized controlled trial showed Pocket PATH's superiority to usual care for promoting the self-management behaviors of adherence, self-monitoring and communication with clinicians during posttransplant year 1. Its long-term impact was unknown. In this study, we examined associations between Pocket PATH exposure during year 1 and longer term clinical outcomes-mortality and bronchiolitis obliterans syndrome (BOS)-among 182 recipients who survived the original trial. Cox regression assessed whether (a) original group assignment and (b) performance of self-management behaviors during year 1 predicted time to outcomes. Median follow-up was 5.7 years after transplant (range 4.2-7.2 years). Pocket PATH exposure had no direct effect on outcomes (p-values >0.05). Self-monitoring was associated with reduced mortality risk (hazard ratio [HR] 0.45; 95% confidence interval [CI] 0.22-0.91; p = 0.027), and reporting abnormal health indicators to clinicians was associated with reduced risks of mortality (HR 0.15; 95% CI 0.04-0.65; p = 0.011) and BOS (HR 0.27; 95% CI 0.08-0.86; p = 0.026), regardless of intervention group assignment. Although Pocket PATH did not have a direct impact on long-term outcomes, early improvements in self-management facilitated by Pocket PATH may be associated with long-term clinical benefit.

Long-Term Medical and Psychosocial Outcomes in Living Liver Donors.

Due to the enduring organ shortage, living donor liver transplantation has been a valuable treatment strategy for advanced liver disease patients for over 20 years. A variety of reviews have summarized the extensive data now available on medical and psychosocial risks to living donors in the aftermath of donation. However, evidence on donor medical and psychosocial outcomes beyond the first year postdonation has not been synthesized in any previous review. The evidence base on such "long-term" outcomes has been growing in recent years. A review of this evidence would therefore be timely and could serve as an important resource to assist transplant centers in their efforts to fully educate prospective donors and gain informed consent, as well as develop appropriate postdonation clinical care and surveillance plans. We reviewed recent literature on long-term donor outcomes, considering (a) medical outcomes, including mortality risk, rates of complications, abnormalities detected in laboratory testing, and the progress of liver regeneration; and (b) donor-reported psychosocial outcomes reflecting physical, emotional, and interpersonal/socioeconomic well-being, as well as overall health-related quality of life. We summarize limitations and gaps in available evidence, and we provide recommendations for future research and clinical care activities focused on long-term outcomes in liver donors.

Preventive intervention for living donor psychosocial outcomes: feasibility and efficacy in a randomized controlled trial.

There are no evidence-based interventions to prevent adverse psychosocial consequences after living donation. We conducted a single-site randomized controlled trial to examine the postdonation impact of a preventive intervention utilizing motivational interviewing (MI) to target a major risk factor for poor psychosocial outcomes, residual ambivalence (i.e. lingering hesitation and uncertainty) about donating. Of 184 prospective kidney or liver donors, 131 screened positive for ambivalence; 113 were randomized to (a) the MI intervention, (b) an active comparison condition (health education) or (c) standard care only before donation. Ambivalence was reassessed postintervention (before donation). Primary trial outcomes-psychosocial variables in somatic, psychological and family interpersonal relationship domains-were assessed at 6 weeks and 3 months postdonation. MI subjects showed the greatest decline in ambivalence (p = 0.050). On somatic outcomes, by 3 months postdonation MI subjects reported fewer physical symptoms (p = 0.038), lower rates of fatigue (p = 0.021) and pain (p = 0.016), shorter recovery times (p = 0.041) and fewer unexpected medical problems (p = 0.023). Among psychological and interpersonal outcomes, they had a lower rate of anxiety symptoms (p = 0.046) and fewer unexpected family-related problems (p = 0.045). They did not differ on depression, feelings about donation or family relationship quality. The findings suggest that the intervention merits testing in a larger, multisite trial.

Early treatment of depressive symptoms and long-term survival after liver transplantation.

While depression after liver transplantation (LTX) is associated with decreased survival, the effects of treating depression remain unknown. We assessed a previously described, prospective cohort of 167 patients transplanted for alcohol-related liver disease from 1998 to 2003. Depressive symptoms were measured with the Beck Depression Inventory serially throughout the first posttransplant year. Adequacy of antidepressant treatment was measured with the Antidepressant Treatment History Form. Using Cox-proportional Hazards modeling, survival times were assessed for recipients with no depression versus depression with adequate medications versus depression with inadequate medications. Seventy-two recipients had depressive symptoms in the first posttransplant year. Of these, 43% (n=31) received adequate pharmacotherapy and 57% (n=41) received inadequate (n=7) or no pharmacotherapy (n=34). After a median follow-up time of 9.5 years, 32% of the inadequately treated depressed group survived versus 52% of the adequately treated group and 56% of the nondepressed group (p=0.006). Compared to the nondepressed group, those with adequately treated depression had no significant difference in survival. However, recipients with depression and inadequate pharmacotherapy had decreased survival times compared to nondepressed recipients (HR for death=2.44, 95% CI=1.45, 4.11), controlling for other known confounders. The factor most strongly linked to long-term mortality after liver transplantation in this cohort was untreated depression.

Predictors and outcomes of health-related quality of life in caregivers of cardiothoracic transplant recipients.

Cardiothoracic transplant programs generally require that transplant recipients have family caregivers to assist them posttransplant. The burden of caregiving on the family members remains poorly understood. If caregivers' well-being is compromised by caregiving, it may bode poorly for transplant recipients' own health in the long-term posttransplant. We examined caregiver health-related quality of life (HRQOL) during the first year after their family member's transplant, its predictors and its relationship to subsequent patient survival. Adult (aged 18+) caregivers of 242 cardiothoracic transplant recipients (lung = 134; heart = 108) completed assessments of demographics, psychosocial characteristics and caregiver burden at 2 months posttransplant, and HRQOL at 2, 7 and 12 months posttransplant. Recipients' survival time was obtained from medical records. Caregiver HRQOL was generally high across the first-year posttransplant in emotional and social functioning; caregiver physical functioning significantly worsened. There were no differences by type of recipient transplant. Greater caregiver burden predicted poorer caregiver HRQOL in several physical domains at 12 months posttransplant. Transplant recipients whose caregivers had lower perceived general health at 12 months posttransplant showed poorer survival rates during the subsequent 7 years of follow up. Transplant teams should identify those caregivers at risk for poorer general health posttransplant to maximize positive outcomes for the entire family.

Trajectories of change in quality of life in 12-month survivors of lung or heart transplant.

Survival and functional outcomes for lung transplant recipients continue to lag behind those for heart recipients. Whether these poorer physical outcomes translate into poorer quality of life (QOL) for lung recipients relative to heart recipients is unknown. Lung versus heart transplant recipients' perceptions of QOL were longitudinally compared at three time-points across the first year posttransplant. Additionally, potentially important predictors of patient QOL were examined. Adult transplant recipients (N = 199) participated in semi-structured interviews that included measures of QOL, optimism, mastery, social support, religiosity and coping. Temporal patterns of QOL change were compared between lung and heart recipients who survived until 1 year posttransplant using mixed-model, hierarchical analysis of variance (ANOVA). Demographic and psychosocial predictors were examined with multiple regression analysis to identify the unique effects of each variable on QOL 1 year posttransplant. While heart recipients' QOL across several domains was higher shortly after transplant, lung patients' QOL improved and was equivalent to that of heart recipients by 1 year posttransplant. Greater optimism and support from friends predicted better QOL in physical, psychological and social domains. Conversely, avoidant coping strategies predicted poorer physical functioning. Thus, while clinical interventions designed to improve QOL posttransplant should be tailored to transplant recipients' initial psychosocial assets and liabilities, they need not be distinguished by transplant type.

Prevalence and risk of depression and anxiety-related disorders during the first three years after heart transplantation.

Although poor psychological adjustment to organ transplantation appears to be a major contributor to reduced quality of life and increased physical morbidity, the prevalence and risk factors for psychiatric disorder have not been considered beyond the first 12-18 months after transplantation. The authors enrolled a representative sample of 191 heart transplant recipients in a prospective examination of the prevalence, clinical characteristics, and risk factors for DSM-III-R major depressive disorder (MDD), generalized anxiety disorder (GAD), associated adjustment disorders, and posttraumatic stress disorder related to transplant (PTSD-T) during the 3 years postsurgery. Survival analysis indicates that cumulative risks for disorder onset were MDD, 25.5%; adjustment disorders, 20.8% (17.7% with anxious mood); PTSD-T, 17.0%; and any assessed disorder, 38.3%. There was only one case of GAD. PTSD-T onset was limited almost exclusively to the first year posttransplant. Episodes of MDD (but not anxiety disorders) that occurred later posttransplant (8 to 36 months postsurgery) were more likely than early posttransplant episodes to be treated with psychotropic medications. For both MDD and anxiety disorders, later episodes were less likely to be precipitated by transplant-related stressors than other life stressors. Factors increasing cumulative risk for psychiatric disorder posttransplant included pretransplant psychiatric history, female gender, longer hospitalization, more impaired physical functional status, and lower social supports from caregiver and family in the perioperative period. Risk factors' effects were additive; the presence of an increasing number of risk factors bore a dose-response relationship to cumulative risk of disorder.

Psychosocial assessments and outcomes in organ transplantation.

A qualitative review was conducted to define the term psychosocial as applied to transplant patients and to summarize evidence regarding the role and impact of psychosocial assessments and outcomes across the transplant process. English-language case series and empirical studies from January 1970 through April 1990 that were abstracted in Medline and Psychological Abstracts or listed in publications' bibliographies were used as data sources. A qualitative analysis was performed to determine the depth of the case reports and whether the empirical reports obtained statistically reliable, clinically significant findings. The authors conclude that psychosocial assessments differ in content and application to candidate selection depending on the transplant program. Psychosocial status before transplant does not consistently affect medical outcomes after transplant. Psychosocial status generally improves with transplant, although difficulties are prevalent in psychological adjustment and in compliance with medical regimens. Psychiatric history can predict psychological outcomes after transplant but does not consistently predict compliance. Social supports and coping strategies strengthen psychosocial outcomes. Posttransplant psychosocial outcomes may predict physical morbidity and mortality.

Elevated blood ethanol levels caused by 'non-alcoholic' beer.

With the availability of non-alcoholic beer, many patients are substituting non-alcoholic beer for regular beer. Moreover, several clinicians advocate the use of non-alcoholic beer by alcoholics when there is a possibility of relapse. However, patients with alcoholic end-stage liver disease can accumulate substantial circulating ethanol levels even when they consume non-alcoholic beer. We present a case of a patient with end-stage liver disease who achieved a blood alcohol level of 57 mg/dL after drinking non-alcoholic beer.

Neuropsychiatric side effects of FK506 vs. cyclosporine A. First-week postoperative findings.

The authors studied 31 liver transplant patients to compare neuropsychiatric side effects of a newer immunosuppressant, FK506, to cyclosporine A (CYA). Patients were randomly assigned to either FK506 or CYA. At the 1-week postoperative stage, cognitive status was assessed with the Mini-Mental State Exam, Trailmaking Tests (TMT) A and B, Delirium Rating Scale, and a neuropsychiatric symptom checklist. No statistically significant differences were found on any outcome variable between these two drugs, though scores on the TMTs were impaired as compared with published norms. The FK506 patients had moderately impaired TMT scores, whereas the CYA patients had only mild impairment. The patients demonstrate good cognitive recovery at 1 week post-transplantation, with only mild evidence of cognitive impairment.

Prospective study of FK506 side effects: anxiety or akathisia?

FK506 is a macrolide immunosuppressant agent used in solid organ and bone marrow transplantation and for autoimmune disorders. FK506 is reported to have a number of neuropsychiatric side effects, including anxiety and tremor. Because FK506 was implicated in causing akathisia in a case report, we did a prospective, cross-sectional study of 25 renal transplant recipients to determine whether akathisia occurred and/or had a relationship to FK506 plasma levels. The Symptom Checklist-90-R, Hamilton Anxiety (HAM-A), and Akathisia Rating (ARS) scales were administered. Higher FK506 plasma levels correlated with higher HAM-A scores. ARS scores did not correlate with FK506 plasma levels; however, when FK506 plasma levels were divided into "high" (> or = 0.9 ng/mL) and "low" (< 0.9 ng/mL) groups, total ARS and HAM-A scores were significantly higher in the "high" group. We discuss implications of these findings as well as management.
