Manuel de bonnes pratiques professionnelles des centres d’investigation clinique

2012

Resume Les centres d’investigation clinique (CIC) sont des structures de recherche clinique academiques appartenant a un reseau national, coordonne par l’Institut national de la sante et de la recherche medicale (Inserm) et la Direction generale de l’offre de soins (DGOS), comportant des groupes de travail et des reseaux thematiques. Le groupe « Harmonisation des procedures des CIC » (HPCIC) a elabore un manuel de bonnes pratiques professionnelles, presente dans cet article. Le manuel a ete elabore par consensus, relu par les coordonnateurs des CIC, des experts externes, et valide par des representants des deux tutelles Inserm et DGOS. Le manuel de bonnes pratiques professionnelles des CIC …

The future of Extracellular Vesicles as Theranostics – an ISEV meeting report

2020

ABSTRACT The utilization of extracellular vesicles (EVs) in clinical theranostics has rapidly advanced in the past decade. In November 2018, the International Society for Extracellular Vesicles (ISEV) held a workshop on “EVs in Clinical Theranostic”. Here, we report the conclusions of roundtable discussions on the current advancement in the analysis technologies and we provide some guidelines to researchers in the field to consider the use of EVs in clinical application. The main challenges and the requirements for EV separation and characterization strategies, quality control and clinical investigation were discussed to promote the application of EVs in future clinical studies.

Prognostic Factors in APL

2018

The prognosis of acute promyelocytic leukemia (APL) has significantly improved since the introduction of anthracyclines, but especially after the advent of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). The identification of prognostic factors is a key process in clinical investigation, since their recognition allows the stratification of disease risks and promotes refined therapeutic adjustments. In fact, most treatments are now designed following risk-adapted strategies in order to optimize the therapeutic efficacy and minimizing side effects. The efficacy of treatment is one major determinant in prognosis. Therefore, the impact of a number of disease and patient characteristi…

Measurement of Fractional Exhaled Nitric Oxide: Comparison of Three Different Analysers

2019

<b><i>Background:</i></b> Fractional exhaled nitric oxide (FeNO) is a surrogate marker for airway inflammation, supporting the diagnostic pathway and treatment decisions for asthma patients. <b><i>Objectives:</i></b> Aim of this study was to compare the new analyser Vivatmo pro (Bosch, BV) with NIOX VERO (Circassia, CN) and CLD (Ecomedics, EC). <b><i>Methods:</i></b> In 100 asthmatics (median 53 years [range 20–87], 62% female, 86% on inhaled corticosteroids [mean 1,300 μg beclomethasone dipropionate or equivalent], 35% treated with biologics) 2 FeNO measurements per device were performed. Additionally, the success rate…

Overview of ambulatory blood pressure monitoring in childhood and pregnancy.

2001

Despite the fact that the study and applicability of ambulatory blood pressure in children and pregnant women share characteristics which limit the potential development of knowledge for their use, advances produced in the last few years provided the present knowledge regarding the significance and the potential use of ambulatory blood pressure in children and in the pregnant women. In children ambulatory blood pressure monitoring is useful for the diagnosis of mild hypertensives, assessment of refractory hypertension, therapeutic trials with antihypertensive drugs, and clinical investigation when BP is one of the parameters to be taken into account and/or when subtle BP abnormalities are t…

Applying extracellular vesicles based therapeutics in clinical trials - an ISEV position paper.

2015

Extracellular vesicles (EVs), such as exosomes and microvesicles, are released by different cell types and participate in physiological and pathophysiological processes. EVs mediate intercellular communication as cell-derived extracellular signalling organelles that transmit specific information from their cell of origin to their target cells. As a result of these properties, EVs of defined cell types may serve as novel tools for various therapeutic approaches, including (a) anti-tumour therapy, (b) pathogen vaccination, (c) immune-modulatory and regenerative therapies and (d) drug delivery. The translation of EVs into clinical therapies requires the categorization of EV-based therapeutics …

MHCII-independent CD4+ T cells protect injured CNS neurons via IL-4

2015

A body of experimental evidence suggests that T cells mediate neuroprotection following CNS injury; however, the antigen specificity of these T cells and how they mediate neuroprotection are unknown. Here, we have provided evidence that T cell-mediated neuroprotection after CNS injury can occur independently of major histocompatibility class II (MHCII) signaling to T cell receptors (TCRs). Using two murine models of CNS injury, we determined that damage-associated molecular mediators that originate from injured CNS tissue induce a population of neuroprotective, IL-4-producing T cells in an antigen-independent fashion. Compared with wild-type mice, IL-4-deficient animals had decreased functi…

Antigen-Driven T-Cell Selection in Patients with Cervical Cancer as Evidenced by T-Cell Receptor Analysis and Recognition of Autologous Tumor

2002

ABSTRACTWe characterized the T-cell receptor (TCR) repertoire in freshly harvested tumor lesions, in short-term-expanded CD4+tumor infiltrating lymphocytes (TIL) as well as in CD4+and CD8+peripheral blood lymphocytes (PBL) from three patients with cervical cancer. Skewing of the T-cell repertoire as defined by measuring the length of the complementarity-determining region 3 (CDR3) of the TCR VA and VB chains was observed in CD8+PBL, in freshly harvested tumor tissue, as well as in CD4+TIL. Comparative analysis of the TCR repertoire revealed unique monoclonal TCR transcripts within the tumor lesion which were not present in PBL, suggesting selection of TCR clonotypes due to antigenic stimula…
