RESUMEN

BACKGROUND: In order to reduce alcohol relapse after liver transplantation (LT), the German national guidelines for waiting-list maintenance and organ allocation demand a minimum 6-month period of alcohol abstinence pre-LT, confirmed by measuring urinary ethyl glucuronide (uEtG). METHODS: Between January 2015 and June 2016, uEtG was measured at least once in 339 cirrhotic patients with an indication for LT at the University Medical Center Mainz. uEtG was measured with an enzyme-linked immunosorbent assay (ELISA) screening test (cutoff value: 500 µg/L). For uEtG values ≥ 500 µg/L, liquid chromatography-mass spectrometry (LC-MS/MS) was performed as a confirmatory assay. Data were collected prospectively in a transplant database. RESULTS: Of the 339 potential liver transplant candidates, uEtG was negative in 86.4 %. Most patients were male (64.3 %), with an average age of 56.42 ±â€Š10.1 years. In the multivariate analysis, mean corpuscular volume (p = 0.001), urinary creatinine (p = 0.001), gamma-glutamyl transferase (p = 0.001), and hemoglobin (p = 0.003) were significantly associated with a positive uEtG test result. The sensitivity of the ELISA screening test was 100 % for uEtG values > 2000 µg/L, as confirmed by LC-MS/MS. CONCLUSION: uEtG is an effective parameter to reveal alcohol consumption by patients on the waiting list for LT. The sensitivity of the ELISA is excellent for uEtG values > 2000 µg/L, for which LC-MS/MS confirmation could be omitted.

RESUMEN

Transplant medicine in Germany is regulated by mandatory guidelines of the German Medical Association, the transplant law passed in 1997 serving as the legal basis. In 2012 a comprehensive modification of the guideline procedure was initiated. Since then, all guidelines are subject to an elaborate revision process. The present contribution initially depicts relevant background information and explains the formal aspects of the guideline procedure. Subsequently, the psychologically/psychosomatically relevant contents of the guidelines for organ transplantation are presented. With regard to this matter, first of all the state of the guidelines prior to the current revisions is described. Afterwards, already adopted revisions as well as published drafts are explicated, followed by the authors' evaluation of the revisions and recommendations for further revisions to be pursued. In addition, recommendations on psychosocial aspects regarding the evaluation and follow-up in living organ donation are presented, which have been submitted in similar form to the German Medical Association for a currently drawn up guideline.

RESUMEN

For the last few years, the German Medical Association's guidelines for transplant medicine have been subject to an extensive revision process. The present contribution presents recommendations regarding the psychosocial evaluation of patients prior to organ transplantation, which were developed by experts from the Psychology/Psychosomatics committee of the German Transplant Society with the aim to incorporate the recommendations into the guidelines. The main objective is to establish a mandatory psychosocial evaluation for all patients prior to their admission to the transplant waiting list. Contents, potential contraindications, and the procedure of the evaluation are described. Furthermore, the qualification deemed necessary for the examiners is addressed in detail. Finally, the future need for action is determined.

RESUMEN

Aim Since there is no consensus about how to perform the predonation psychosocial evaluation of living kidney donor candidates, this is conducted differently in German transplant centers. Thus, the goal of the study was to learn more about how psychosocial evaluations are currently conducted in German transplant centers. Methods The psychosocial evaluators of the 38 transplant centers performing kidney transplantations in 2015 were contacted and asked to participate in an anonymous online survey. Results Psychosocial evaluators from 28 (75%) transplant centers responded. In only 30 (4%) of the evaluations contraindications for donation were reported. In most centers the psychosocial evaluation was performed after the completion of all medical tests. The evaluations were realized after only short waiting periods and were reported to be time-consuming. Financial reimbursement was mainly realized by internal cost allocation. In most centers the evaluators used semi-structured interviews. Still, there was limited consensus about structure and content of the psychosocial evaluation. Conclusion Standardization of the psychosocial evaluation process could be helpful to enable comparisons between transplant centers and to achieve equal opportunities for the potential living kidney donors and recipients.

RESUMEN

BACKGROUND: International data on training, work, and lifestyle of transplant physicians and surgeons are scarce. Such data might help in development of uniform education paths and provide insights for young clinicians interested in this field. This study aimed at the evaluation of these data in all transplant-associated medical disciplines. METHODS: A survey on professional and academic training, workload, and lifestyle was generated. The questionnaire was distributed to all members of the German Transplant Association (DTG), utilizing the tool SurveyMonkey(®) . RESULTS: A total of 127 members of the DTG responded (male/female 66.1%/33.9%, 45.8±10.3 years). The majority had been working in transplant medicine for more than 10 years (61.9%). Fifteen respondents (11.8%) obtained an official European certification (European Union of Medical Specialists). A total of 57 (48.3%) respondents worked full time on research during training. The research focus was clinical for most respondents (n=72, 61.5%). An average working time of 62±1.5 h/wk was reported. Fifty-eight percent of all respondents complained of inadequate remuneration and 50% reported inadequate acknowledgment of their professional performance. CONCLUSION: This is the first study reporting characteristics of training, work, and lifestyle in an interdisciplinary cohort of German transplant physicians and surgeons. Enormous efforts in clinical and research work were reported, associated with high rates of professional and financial dissatisfaction.

RESUMEN

Alcoholic liver cirrhosis (ALC) is a commonly accepted indication for liver transplantation (LT). Any alcohol consumption is considered a contraindication for LT. However, the assessment of abstinence in everyday practice mostly relies on patient self-reporting, which must be considered highly unreliable. After consumption, ethanol is eliminated by alcohol dehydrogenase, with methanol accumulating in the blood. Methanol, which is known to be a sensitive and specific indicator for recent alcohol consumption, has not been used for verifying alcohol consumption in LT assessments yet. Therefore, the purpose of this study was to test the feasibility of using methanol testing to identify recent alcohol consumption in LT candidates during routine and short-notice appointments. We compared methanol and ethanol measurements with self-reported alcohol consumption for 41 patients with ALC during the evaluation process before they were accepted onto the waiting list. In 32 of the 92 blood samples drawn from these 41 patients during the study, a relapse was detected by the methanol test. Both the ethanol test results and the self-reported data were positive in only 3 cases. Thus, the methanol test identified 29 additional cases of alcohol consumption. Furthermore, the methanol test discovered recent alcohol consumption in 5 of 10 transplant patients when both self-reported data and ethanol test results were negative. As a part of blood alcohol analysis, the methanol test is more sensitive than self-reporting and ethanol testing for the detection of recent alcohol consumption. Also, short-notice appointments for blood alcohol analysis reveal more cases of alcohol relapse than routine, long-term appointments. The measurement of methanol as a sensitive screening test for recent alcohol consumption should be implemented both in law and in daily, routine practice.

RESUMEN

We evaluated the safety and efficacy of an escalating dose regimen of pegylated interferon alpha-2a (PEG-IFN(alpha-2a)) and ribavirin in the early phase of recurrent hepatitis C after orthotopic liver transplantation (OLT). In this prospective study, 26 patients transplanted for hepatitis C virus cirrhosis with recurrent hepatitis C were treated 3.4 +/- 3.6 months after OLT and compared with an untreated historical control. PEG-IFN(alpha-2a) was initiated as monotherapy, following stepwise dose escalation up to 180 mug/week and the addition of ribavirin up to 1200 mg/day or maximally tolerated doses for 48 weeks. In the intent-to-treat analysis, 38% showed an early virological response (EVR), 35% an end of treatment response (ETR) and 19% a sustained virological response (SVR). SVR was associated with EVR (P = 0.0001) and cumulative PEG-IFN(alpha-2a) dose (P = 0.04). There was no significant histological improvement compared with untreated patients. There were no treatment-related serious adverse events. Adverse events included leucopenia (77%) and thrombocytopenia (46%). Three patients discontinued therapy due to side effects, fourteen were nonresponders and four relapsers. Treatment with PEG-IFN(alpha-2a) and ribavirin in the acute phase of post-transplant recurrent hepatitis C yielded an EVR of 38% and an SVR of 19%. The combination was safe and well tolerated.
