Alcohol Use in Liver Transplant Recipients With Alcohol-related Liver Disease: A Comparative Assessment of Relapse Prediction Models.

BACKGROUND: The selection of liver transplant (LT) candidates with alcohol-related liver disease (ALD) is influenced by the risk of alcohol relapse (AR), yet the ability to predict AR is limited. We evaluate psychosocial factors associated with post-LT AR and compare the performance of high-risk alcoholism risk (HRAR), sustained alcohol use post-LT (SALT), and the Stanford Integrated Psychosocial Assessment for Transplantation (SIPAT) scores in predicting relapse. METHODS: A retrospective analysis of ALD patients undergoing LT from 2015 to 2021 at a single US transplant center was performed. Risk factors associated with post-LT AR were evaluated and test characteristics of 3 prediction models were compared. RESULTS: Of 219 ALD LT recipients, 23 (11%) had AR during a median study follow-up of 37.5 mo. On multivariate analysis, comorbid psychiatric illness (odds ratio 5.22) and continued alcohol use after advice from a health care provider (odds ratio 3.8) were found to be significantly associated with post-LT AR. On sensitivity analysis, SIPAT of 30 was optimal on discriminating between ALD LT recipients with and without post-LT AR. SIPAT outperformed both the HRAR and SALT scores (c-statistic 0.67 versus 0.59 and 0.62, respectively) in identifying post-LT AR. However, all scores had poor positive predictive value (<25%). CONCLUSIONS: AR after LT is associated with comorbid psychiatric illness and lack of heeding health care provider advice to abstain from alcohol. Although SIPAT outperformed the HRAR and SALT scores in predicting AR, all are poor predictors. The current tools to predict post-LT AR should not be used to exclude LT candidacy.

ACLP Best Practice Guidance: Evaluation and Treatment of Depression in Solid Organ Transplant Recipients.

We present Academy of Consultation Liaison Psychiatry best practice guidance on depression in solid organ transplant (SOT) recipients, which resulted from the collaboration of Academy of Consultation Liaison Psychiatry's transplant psychiatry special interest group and Guidelines and Evidence-Based Medicine Subcommittee. Depression (which in the transplant setting may designate depressive symptoms or depressive disorders) is a frequent problem among SOT recipients. Following a structured literature review and consensus process, the Academy of Consultation Liaison Psychiatry transplant psychiatry special interest group proposes recommendations for practice: all organ transplant recipients should be screened routinely for depression. When applicable, positive screening should prompt communication with the mental health treating provider or a clinical evaluation. If the evaluation leads to a diagnosis of depressive disorder, treatment should be recommended and offered. The recommendation for psychotherapy should consider the physical and cognitive ability of the patient to maximize benefit. The first-line antidepressants of choice are escitalopram, sertraline, and mirtazapine. Treating depressive disorders prior to transplantation is recommended to prevent posttransplant depression. Future research should address the mechanism by which transplant patients develop depressive disorders, the efficacy and feasibility of treatment interventions (both pharmacological and psychotherapeutic, in person and via telemedicine), and the resources available to transplant patients for mental health care.

Cannabinoids and solid organ transplantation: Psychiatric perspectives and recommendations.

Cannabinoid use in patients seeking solid organ transplantation (SOT) is an important and unsettled matter which all transplantation clinicians regularly encounter. It is also a multifaceted, interprofessional issue, difficult for any specialty alone to adequately address in a research article or during clinical care. Such uncertainty lends itself to bias for or against cannabinoid use accompanied by inconsistent policies and procedures. Scientific literature in SOT regarding cannabinoids often narrowly examines the issue and exists mostly in liver and kidney transplantation. Published recommendations from professional societies are mosaics of vagueness and specificity mirroring the ongoing dilemma. The cannabinoid information SOT clinicians need for clinical care may require data and perspectives from diverse medical literature which are rarely synthesized. SOT teams may not be adequately staffed or trained to address various neuropsychiatric cannabinoid effects and risks in patients. In this article, authors from US transplantation centers conduct a systematized review of the few existing studies regarding clinician perceptions, use rates, and clinical impact of cannabinoid use in SOT patients; collate representative professional society guidance on the topic; draw from diverse medical literature bases to detail facets of cannabinoid use in psychiatry and addiction pertinent to all transplantation clinicians; provide basic clinical and policy recommendations; and indicate areas of future study.

Substance use screening in transplant populations: Recommendations from a consensus workgroup.

Transplant patients are frequently treated with substances that have dependence potential and/or they may have a history of substance use disorders. The Psychosocial and Ethics Community of Practice of the American Society of Transplantation formed a Drug Testing Workgroup with participation from members of the Pharmacy Community of Practice and members of the Academy of Consultation-Liaison Psychiatry. The workgroup reviewed the literature regarding the following issues: the role of drug testing in patients with substance use disorders, for patients prescribed controlled substances, legal, ethical and prescription drug monitoring issues, financial and insurance issues, and which patients should be tested. We also reviewed current laboratory testing for substances. Group discussions to develop a consensus occurred, and summaries of each topic were reviewed. The workgroup recommends that transplant patients be informed of drug testing and be screened for substances prior to transplant to ensure optimal care and implement ongoing testing if warranted by clinical history. While use of certain substances may not result in the exclusion for transplantation, an awareness of the patient's practices and possible risk from substances is necessary, allowing transplant teams to screen for substance use disorders and ensure the patient is able to manage and minimize risks post-transplant.

How do you know your consult service is doing a good job? Generating performance measures for C-L service effectiveness.

BACKGROUND: There is no consensus in the literature on measures for evaluating the performance of general hospital Consultation-Liaison psychiatry services. OBJECTIVE: The purpose of this study was to investigate what indicators might be used to this end. METHODS: We surveyed United States Psychosomatic Medicine fellowship directors (n = 53) about the use of performance measures for their psychiatric consultation services. Results of this survey led to the construction of a second survey, which was distributed to the representatives of services calling for psychiatric consultations at our hospital (n = 21); this survey sought to determine the importance of various performance parameters to overall consultee satisfaction. RESULTS: Sixty-three percent of responding psychiatric consult services do not use any of the parameters identified in the literature as performance measures. Consultee satisfaction was endorsed as a valuable performance indicator by 67.7% of them, but no satisfaction rating instrument was identified. The internal survey of consultees identified 11 of 16 candidate parameters as important or very important to consultee satisfaction, of which "consultant understands the core situation and the core question being asked" received the highest rating. CONCLUSIONS: Consultee satisfaction is perceived as a useful global measure of the effectiveness of a psychiatric consult service. We elicited parameters that can be used to create a measurement tool for consultee satisfaction with Consultation-Liaison services. The use of such a tool merits testing in a larger multicenter study.

Human anti-macrophage migration inhibitory factor antibodies inhibit growth of human prostate cancer cells in vitro and in vivo.

Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine, originally discovered for its eponymous effect and now known for pleiotropic biologic properties in immunology and oncology. Circulating MIF levels are elevated in several types of human cancer including prostate cancer. MIF is released presumably by both stromal and tumor cells and enhances malignant growth and metastasis by diverse mechanisms, such as stimulating tumor cell proliferation, suppressing apoptotic death, facilitating invasion of the extracellular matrix, and promoting angiogenesis. Recently described fully human anti-MIF antibodies were tested in vitro and in vivo for their ability to influence growth rate and invasion of the human PC3 prostate cancer cell line. In vitro, the selected candidate antibodies BaxG03, BaxB01, and BaxM159 reduced cell growth and viability by inhibiting MIF-induced phosphorylation of the central kinases p44/42 mitogen-activated protein kinase [extracellular signal-regulated kinase-1 and -2 (ERK1/2)] and protein kinase B (AKT). Incubation of cells in the presence of the antibodies also promoted activation of caspase-3/7. The antibodies furthermore inhibited MIF-promoted invasion and chemotaxis as transmigration through Matrigel along a MIF gradient was impaired. In vivo, pharmacokinetic parameters (half-life, volume of distribution, and bioavailability) of the antibodies were determined and a proof-of-concept was obtained in a PC3-xenograft mouse model. Treatment with human anti-MIF antibodies blunted xenograft tumor growth in a dose-dependent manner. We therefore conclude that the anti-MIF antibodies described neutralize some of the key tumor-promoting activities of MIF and thus limit tumor growth in vivo.
