COVID-19-related medical research: a meta-research and critical appraisal

1/12/2021

 
Picture
As with many fields, science has been put to the test by the coronavirus pandemic. An international team of researchers, led by French scientists, has demonstrated novel scientific practices around Covid-19. Under the pressure of the number of cases and the urgent need to understand the virus, many research groups have shared results, sometimes to the expense of high scientific standards.

During the first wave of the Covid-19 epidemic, medical research saw a historic number of studies on the coronavirus published in a short period of time. An international consortium of experts in medical methodology undertook the major challenge of evaluating the Covid-19 research during this first wave.

Assessment of the Utility of Kidney Histology as a Basis for Discarding Organs in the US

12/15/2020

 
Picture
New research indicates that analyses of kidney biopsies from deceased donors don’t provide meaningful information beyond standard assessments of donor and recipient characteristics. In addition, the study revealed that relying on these analyses has prompted the discard of many potentially suitable organs for transplantation in the United States. The findings appear in JASN.

Despite a critical scarcity of organs available for transplantation, thousands of deceased donor kidneys are discarded each year in the United States.

Ce poste de technicien d'étude clinique est à pourvoir au sein de l’unité de recherche INSERM U970 dans l’équipe 11 : Approches multidimensionnelles en transplantation d’organes dirigée par le Pr Alexandre Loupy.
Ce poste s’intègre au sein d’un projet se focalisant sur la transplantation pulmonaire. Actuellement, la prédiction du succès ou de l’échec d’une greffe pulmonaire reste difficile car les mécanismes immunologiques autour d’un greffon sont mal connus.
Notre équipe s’intéresse aux approches personnalisées pour la prédiction de risque post-transplantation (notamment les risques de survenue de rejet) par l’intégration d’informations multidimensionnelles. Cela regroupe des données provenant de la clinique, de l’histologie classique, de la biologie et éventuellement des données provenant de technologies innovantes en immunologie, biologie moléculaire, génétique et biomarqueurs.

Statistical performance of 16 posttransplant risk scores in a contemporary cohort of heart transplant recipients

7/28/2020

 
Accurate risk stratification of early heart transplant failure is required to avoid futile transplants and rationalize donor selection. We aimed to evaluate the statistical performance of existing risk scores on a contemporary cohort of heart transplant recipients.

After an exhaustive search, we identified 16 relevant risk scores. From the UNOS database, we selected all first noncombined adult heart transplants performed between 2014 and 2017 for validation. The primary endpoint was death or retransplant during the first year posttransplant.

​For all scores, we analyzed their association with outcomes, sensitivity, specificity, likelihood ratios, and discrimination (concordance index and overlap of individual scores). The cohort included 9396 patients. All scores were significantly associated with the primary outcome (P < .001 for all scores). Their likelihood ratios, both negative and positive, were poor. The discriminative performance of all scores was limited, with concordance index ranging from 0.544 to 0.646 (median 0.594) and an important overlap of individual scores between patients with or without the primary endpoint. Subgroup analyses revealed important variation in discrimination according to donor age, recipient age, and the type of assist device used at transplant.

Our findings raise concerns about the use of currently available scores in the clinical field.

A considerable decline in the number of organ transplants since the start of the COVID-19 pandemic in France and the US

5/12/2020

 
​​A French-American study conducted by researchers from the Paris Transplant Group (University of Paris, Inserm and AP-HP) just published in The Lancet reveals a more than 90% drop in the number of organ procurement and transplants during the COVID-19 pandemic in France. The trend, which is also continuing across the Atlantic, poses a life-threatening risk to the thousands of people waiting for transplants in France and the United States.

Identification and characterization of trajectories of cardiac allograft vasculopathy after heart transplantation

5/4/2020

 
Picture
Every year, tens of thousands of deaths are due to end-stage heart failure in Europe and in the US combined. Heart transplantation is the ultimate treatment, but its number is dramatically limited due to the shortage of organs in those countries. 
​
​In the same time, the chances of survival beyond one year after transplantation have remained unchanged in recent years, despite significant progress in immunosuppressive therapy and patient care.
One of the most common reasons for long-term graft failure and patient death is an accelerated form of coronary artery disease called cardiac allograft vasculopathy. It is a frequent complication that affects up to half of patients within 10 years following heart transplantation. Yet, until now, little has been known about the different evolutive profiles of cardiac allograft vasculopathy and their risk factors.

Prediction system for risk of allograft loss in patients receiving kidney transplants: international derivation and validation study

3/3/2020

 
Picture
The first universal algorithm for predicting the risk of kidney transplant loss, named iBox, has been developed, validated and just made public by teams from Europe and the US.

​The iBox is designed for clinicians to personalize and improve patient follow-up. The iBox could also accelerate the development of new immunosuppressive treatments by reducing the duration of clinical trials and defining a valid surrogate endpoint.
Chronic kidney disease affects 1 out of 10 people worldwide and is steadily increasing. When it reaches end-stage renal disease and endangers the lives of patients, dialysis or transplantation is required. ​
