Immunosuppressant drugs and quality-of-life outcomes in kidney transplant recipients: An international cohort study (EU-TRAIN).

Front Pharmacol

April 2023

Paris Translational Research Center for Organ Transplantation, Institut National de la Santé et de la Recherche Médicale UMR-S970, Université de Paris, Paris, France.

Patient-Reported Outcomes (PRO) integrate a wide range of holistic dimensions that arenot captured within clinical outcomes. Particularly, from induction treatment to maintenance therapy, patient quality-of-life (QoL) of kidney transplant recipients have been sparsely investigated in international settings. In a prospective, multi-centric cohort study, including nine transplant centers in four countries, we explored the QoL during the year following transplantation using validated elicitation instruments (EQ-5D-3L index with VAS) in a population of kidney transplant patients receiving immunosuppressive therapies.

BACKGROUND In kidney transplantation, the association of cold ischemia time (CIT), anastomosis time (AT), and delayed graft function (DGF) is particularly detrimental in grafts from marginal donors; however, actual cut-off criteria are still debated. MATERIAL AND METHODS Data from patients >65 years (n=193) and patients <65 years (n=1054) transplanted between 2000 and 2010 were retrospectively analyzed regarding the age-dependent impact of ischemia times and DGF. RESULTS Overall death censored graft survival was inferior for ECD/DCD organs.

Optimizing clinical utilization and allocation of older kidneys.

Curr Opin Organ Transplant

August 2015

Department of General, Visceral and Transplantation Surgery, Charite Virchow Clinic, Berlin, Germany.

Purpose Of Review: With a persisting organ shortage and constant high discard rates, there is an urgent need to optimize the outcome and allocation of marginal grafts.

Recent Findings: The Eurotransplant Senior Program was established as an 'old-for-old' allocation system emphasizing on the importance of keeping ischemic times short when utilizing marginal grafts. In addition to refined allocation systems, brief cold ischemic times, novel preservation techniques, a careful assessment of organ quality the utilization of dual kidney transplantation and donation after cardiac death kidneys from elderly donors may all help to increase the supply for renal transplantation.

Feasibility of hepatic radiofrequency ablation in patients with bilioenteric anastomoses.

Hepatogastroenterology

April 2011

Dept. General, Visceral & Transplantation Surgery, Charité Virchow-Clinic, Berlin, Germany.

Background/aims: Radiofrequency ablation (RFA) in the liver is contraindicated in the presence of bilioenteric anastomoses, because it predisposes to occasionally devastating infectious complications. The purpose of this single-center experience is to demonstrate the technical feasibility of such procedures.

Methodology: Patients with bilioenteric anastomoses were offered ultrasound-guided RFA, if an interdisciplinary tumor board endorsed this decision, or an intraoperative opportunity to achieve a tumor-free situation emerged.

Intrapartum translabial ultrasound (ITU): sonographic landmarks and correlation with successful vacuum extraction.

Ultrasound Obstet Gynecol

November 2006

Department of Obstetrics, Charité Virchow Clinic, Berlin, and Heinrich-Heine-University, Düsseldorf, Germany.

Objective: Having studied intrapartum translabial ultrasound (ITU) to define easily obtainable sonographic criteria during maternal pushing, we used it dynamically immediately before vacuum extraction to determine its use in predicting successful operative vaginal delivery.

Methods: In a pilot study, maternal and fetal landmarks were determined sonographically during maternal pushing from a mid-sagittal translabial insonation using a curved array transducer in women delivering singleton fetuses in cephalic presentation spontaneously. With this transducer placed infrapubically ('infrapubic plane'), easily obtainable landmarks and signs were: (i) the 'infrapubic line', perpendicular to the long axis of the pubic joint and extending dorsally from its inferior margin in a mid-sagittal plane, (ii) the widest fetal head diameter and its movement with regard to the infrapubic line during pushing, and (iii) the 'head direction' with respect to the long axis of the symphysis.
