RESUMO

UNLABELLED: Transplant Psychiatrist: "Why is it important to take (routine) medications after transplantation?" Transplant candidate: "To protect the liver." Doctor: "How?" PATIENT: "I don't know." Doctor: "Think about it for a moment." PATIENT: "To prevent rejection and infection." Doctor: "Which one: rejection or infection?" PATIENT: "Both." This article reports significant conceptual limitations in patient medical knowledge. In the course of customary comprehensive psychiatric evaluation, patients with end-stage renal and/or hepatic disease were asked about knowledge of benefits and side effects of required post-transplant medication. Liver transplant candidates were asked about their understanding of primary organ function and instructed in reference to components of Model for End-stage Liver Disease status on the deceased donor transplant list. Candidates for renal transplantation were selectively asked about risks regarding medical dietary compliance, including dangers of hyperkalemia. PATIENTs had less than expected understanding of required immunosuppression. Liver transplant candidates, with infrequent exception, described the organ as a filter. Those with medical compliance problems related to end-stage renal disease had limited understanding of the kidney's role in homeostasis and impact of hyperkalemia on neurologic function. Additional teaching centered on narrative and analogy specific to individual life experience and skills. Historical reference to Sir Peter Medawar's Nobel Prize-winning work on skin allograft failure for treatment of World War II burn victims effectively illustrated the primacy of immunosuppression for successful organ transplantation. PATIENTs were receptive to this teaching approach. Many expressed gratitude for improved understanding. Clinical awareness of patient skills and life experience can enrich understanding of transplantation objectives and importance of medical compliance.

RESUMO

The global demand for human organs has set the stage for an exploding and poorly understood global business in human organs. Whenever there is demand for a product, the opportunity for business arises. The form that a business takes is dependent on a complex network of inputs and outputs, each affecting the others. Historically, the details of any specific market are drastically underestimated. Nowhere is this truer than in the market of human organs. The drivers, which propel the "goods" of human organs, form a flourishing business. Critical analysis is essential to understanding of the supply and demand sides and to determine the role of government in regulating the industry. Governmental groups have dismissed formation of a regulated market for organ sales. The concept is nonetheless a topic of active discussion, motivated by the suffering of patients in need of organs and exploitation of the victims of human trafficking. Ethical principles have been invoked on each side of the ensuing debate. Theory in the absence of sufficient data is shaky ground for enactment of new policy. The Aristotelian concept of "practical wisdom" and the pragmatism of William James illuminate the importance of scientific investigation as guide to policy formation. How will stakeholders benefit or lose? What impact might be anticipated in regard to organized medicine's social contract? What can we learn about cross-cultural differences and their effect on the global landscape?

RESUMO

The authors examined psychiatric disorders among two samples of patients who underwent living-related transplant (LRT) for kidney and liver failure. The postoperative prevalence of psychiatric disorders for adult transplant recipients was highest the first 3 months posttransplant. The incidence of psychiatric disorders in the adult recipients with living-related liver transplant (LRLT) was higher (54%, 22 of 41) than that of adult recipients with living-related kidney transplant (LRKT) (28%, 65 of 234). Twelve (80%) of the 15 adult LRLT recipients with adult child-to-parent donors exhibited paradoxical psychiatric syndrome (PPS). Among the 12 affected recipients, guilt-based psychiatric disorders of various types occurred despite successful operative outcome for both donor and recipient. The higher rate of psychiatric disorders among adult LRLT recipients was associated with the occurrence of PPS among recipients of an adult-child allograft. These results signal a new challenge for consultation psychiatrists working with transplant patients.

RESUMO

The expanding field of bioethics has created a need in psychiatry for rapid access to the complex bioethics literature. This is especially true in consultation-liaison work. An annotated bibliography was created by a task force of the Academy of Psychosomatic Medicine charged with exploring how psychiatrists function on bioethics committees. The bibliography is organized into headings that reflect how bioethical problems came to the attention of psychiatrists. Introductory references allow the reader an overview of the history of bioethics and a selection of useful textbooks. References are provided explaining how ethical principles are used. References are also organized by areas of medical work frequently visited by consultation-liaison psychiatrists.

RESUMO

OBJECTIVE: The aim of this study was to examine the awareness of resting heartbeat in heart transplantation recipients, compare it with that found in other medical populations, and determine whether clinical characteristics are associated with accurate heartbeat awareness. METHODS: Eligible patients underwent a research battery consisting of a heartbeat detection task and self-report questionnaires assessing cardiac symptoms, psychosocial variables, and cognitive function. The accurate awareness of resting heartbeat was determined by presenting the patients with auditory stimuli at each of six different delays following the R wave on the ECG. Patients then selected the tones that they thought coincided with the sensation they had of their heart beating. The patients' physicians rated their cardiac morbidity. The results were contrasted with comparable data obtained in previous work with other ambulatory medical populations. RESULTS: Forty-one consecutive heart transplantation recipients who survived for at least 3 months after surgery were eligible. Thirty-four (82.9%) of them were studied and complete data were obtained on 26 (63.4%). Nine patients (34.6%) were reliably able to detect their resting heartbeat. When compared with the 17 patients who were not accurately aware of their heartbeat, the two groups did not differ significantly in cardiac morbidity, cognitive brain dysfunction, generalized psychiatric distress, depression, somatization, or hypochondriacal attitudes. A significantly higher proportion of heart transplantation recipients were accurately aware of their heartbeat than was found in a sample of general medical outpatients and in asymptomatic, nonpatient volunteers. CONCLUSIONS: One-third of heart transplant recipients are accurately aware of resting heartbeat, despite the absence of cardiac innervation.

RESUMO

Rapid advances of the past 15 years have resolved many of the technical and immunologic limitations to organ transplantation. With the success rates that can now be achieved, there is increased attention to the limited supply of donor organs and to cost considerations, the remaining obstacles to wide application of organ transplantation. Competition for organs and for funding demands greater focus on patient selection and resource allocation. As Charles Taylor, philosopher and political scientist, has written, ethical formulations inevitably conflict when each is taken to its logical end point. In the 1960s, a life boat ethics framework predominated for selection of transplant recipients. The opposing egalitarian framework of recent decades has allowed for enrollment of older transplant recipients and those with histories of substance abuse. In the United States, alcoholic liver disease has been the most common indication for orthotopic liver transplantation since 1987. Among those awaiting transplantation, urgency has been a priority over time waiting. But many potential transplant candidates who are young and who appear relatively stable die while waiting. Despite the shortage of cadaveric organs, physicians and ethicists have for the most part eschewed rewards or reimbursement for living related organ donation. Such conventions are a function of the prevailing zeitgeist and are susceptible to a paradigm shift in parallel with overall changes in societal regulation of medical practice. Theorists and practitioners are immersed in the trends of the day and the approach at each moment seems preferable to that of the moment preceding. From a practical standpoint it may be possible to bridge disparate ethical constructs. For example, in the wait for solid organ transplantation, a bicameral approach could alternatively accommodate time waiting and urgency. Selection of older patients and those with a past substance abuse history could be limited to those with the best prognosis for compliance and posttransplantation quality of life. Living organ donors and families of nonliving donors could receive incentives of a noncoercive nature that would stimulate participation without sacrificing altruism. Creative approaches are needed to improve fairness and efficacy in solid organ transplantation.

RESUMO

Although cytomegalovirus (CMV) is rarely cultured from peripheral-blood leukocytes of immunocompetent patients, it may be cultured from up to 60% of renal transplant recipients, 1 to 4 months after transplantation. During this same period, renal transplant recipients are often referred for psychiatric evaluation. Since CMV may infect the central nervous system, the relationship between isolation of CMV from peripheral-blood leukocytes (viremia) and psychiatric evaluation was investigated in 80 renal allograft recipients at the Massachusetts General Hospital. Five of 16 (31%) patients with viremia and 7 of 64 (11%) patients without viremia required psychiatric consultation (P = 0.04, two-tailed Fisher exact test). CMV viremia may be an important but treatable contributor to psychiatric symptoms in the transplant recipient.

RESUMO

Psychiatry plays an essential role in the selection and preoperative care of liver transplant patients. Unique to liver transplantation are the preponderance of candidates with alcoholic end-stage organ failure and also the reversibility of encephalopathy with postoperative normalization of hepatic function. The expense of liver transplantation necessitates documentation of quality of life among recipients. It can also be postulated that a "ripple effect" does occur, in which favorable operative outcomes provide a meaningful and beneficial effect on social networks of transplant candidates and on society in general.

RESUMO

Psychoactive drugs provide an essential intervention in the care of organ transplant recipients, yet little is known of their effect on immunological function. Human and animal data on immunological effects of neuroleptic (e.g., haloperidol, phenothiazines) and antidepressant agents (e.g., tricyclic antidepressants, fluoxetine) lead to conflicting hypotheses. Lithium carbonate acts through the phosphoinositide system and has a bipolar effect on neuronal activity. Lithium is known to have immune-enhancing properties and is difficult to administer in the peritransplant period but nonetheless deserves study for possible beneficial effects on allograft function.

RESUMO

Organ transplantation in the 1960s proceeded according to a "lifeboat" ethics formula with physicians acting as "gatekeepers." Selection of transplant recipients is now based on medical urgency and waiting time. Some candidates continue to be given low priority by virtue of psychological impairment. The three As--advanced age, acquired immune deficiency syndrome (or positive human immunodeficiency virus status), and alcoholism--also stand out as characteristics that tend to exclude candidates. Cancer is another relative or absolute contraindication to transplantation. This article focuses retrospectively on the psychosocial and medical aspects of the decision to include six patients at Massachusetts General Hospital who were selected for organ transplantation despite their borderline candidacy. The authors introduce four lines of thinking that decision-makers might use to either include or exclude marginal candidates (e.g., the physician's interpretation of what duty requires, the patient's or surrogate's wishes, cost-benefit considerations, or the need for research to improve our scientific understanding of transplantation issues) and discuss an ethical approach that supports each line of thinking. The authors conclude that not all of the ethical approaches lead practitioners and policymakers to the same conclusions regarding the optimum size of or who should be a part of the recipient pool. The future of who receives transplants and why depends at least in part on the underlying ethical considerations that are deemed appropriate as determinants of practice and policy.

RESUMO

Depression has been previously associated with immunologic dysfunction. The lymphocyte subsets of 10 patients with major depression were found to show a mean T4-T8 (helper-suppressor) ratio lower than that of controls, a difference attributable to increased numbers of suppressor cells in the depressed group. One possible cause of increased suppressor cells is prior or current viral infection.

RESUMO

Twenty-one patients with postherpetic neuralgia of two- to 84-months duration participated in a double-blind, placebo-controlled study of oral acyclovir. Pain perception was assessed with the Melzack Pain Questionnaire at baseline and at two-to six-week intervals during the ensuing six months. Clinically significant pain reduction occurred in eight patients: four received acyclovir, and four received a placebo. Several treatment strategies have been advocated for relief of postherpetic neuralgia. Results of the present study demonstrate the need for a double-blind, placebo-controlled paradigm to substantiate the efficacy of new clinical approaches. The same caveat applies to the more common syndromes encountered in psychiatric practice.

RESUMO

Technical advances in surgery and the new antirejection agents cyclosporine and muromonab-CD3 have led to improved outcome for organ transplantation. Allograft rejection and complications of immunosuppressant therapy are often associated with considerable stress, so availability of psychiatric consultation is a necessity. As a transplant team consultant, the psychiatrist treats perioperative anxiety, depression, and organic brain dysfunction and addresses medical and ethical aspects of patient selection. Studies indicate that many patients with psychopathological conditions have good postoperative results and that most living kidney donors participate spontaneously and consider donation a positive experience.
