Visceral adiposity in patients with psoriatic arthritis and psoriasis alone and its relationship with metabolic and cardiovascular risk
2020
Abstract Background Fat mass distribution, especially in the abdominal visceral region, has been rarely evaluated in patients with PsA or psoriasis (PsO). Methods Patients with PsA and patients with PsO alone were evaluated and compared with control subjects (1:1 ratio in each patient group) matched for age, sex and BMI category. Body composition and fat distribution (android and visceral fat) were evaluated by DXA. Anthropometric measurements, disease activity and the systematic coronary risk evaluation (SCORE) cardiovascular risk were assessed. Metabolic parameters (insulin, homeostasis model assessment for insulin resistance), serum adipokines [total and high-molecular-weight adiponectin…
Circulating levels of 3-hydroxymyristate, a direct quantification of endotoxaemia in noninfected cirrhotic patients
2019
IF 4.5; International audience; Background & AimsThe quantification of lipopolysaccharide (LPS) in biological fluids is challenging. We aimed to measure plasma LPS concentration using a new method of direct quantification of 3‐hydroxymyristate (3‐HM), a lipid component of LPS, and to evaluate correlations between 3‐HM and markers of liver function, endothelial activation, portal hypertension and enterocyte damage.MethodsPlasma from 90 noninfected cirrhotic patients (30 Child‐Pugh [CP]‐A, 30 CP‐B, 30 CP‐C) was prospectively collected. The concentration of 3‐HM was determined by high‐performance liquid chromatography coupled with mass spectrometry.Results3‐HM levels were higher in CP‐C patien…
Metronomic cyclophosphamide induces regulatory T cells depletion and PSA‐specific T cells reactivation in patients with biochemical recurrent prostat…
2019
Biochemical recurrence (BCR) occurs in up to 40% of prostate cancer patients after prostatectomy. In our study, we performed an immune monitoring study in 20 prostate cancer patients with BCR previously treated with metronomic cyclophosphamide (mCTX). We observed a decrease of regulatory T cells (Tregs) from 2 months and this was more pronounced after 6 months of mCTX treatment. This drop of Tregs was associated with increased level of activated HLADR+ CD45R0+ T cells in peripheral blood. Furthermore, a reactivation of Th1 polarized anti-PSA T-cell response was detected in BCR patients treated with mCTX. However, dendritic cell subsets counts and activation were not influenced by the treatm…
Naturally Occurring Telomerase-Specific CD4 T-Cell Immunity in Melanoma.
2020
CD4 T cells play a key role in anticancer immunity. In this study, we investigate the clinical relevance of circulating CD4 T helper type 1 (Th1) response against telomerase (anti-TERT Th1 response) in patients with melanoma. The spontaneous anti-TERT Th1 response was detected in 54.5% (85/156) of patients with melanoma before treatment. The prevalence of this systemic response was inversely related to Breslow thickness >1 mm and American Joint Committee on Cancer stage ≥II (P = 0.001 and 0.032, respectively). In contrast to patients treated with targeted therapies, the anti-TERT Th1 immunity was associated with an objective response after immune checkpoint inhibitors treatment. Hence, 86% …
Immunité spécifique anti-télomérase dans le mélanome
2020
La reponse immunitaire lymphocytaire T CD4 Th1 joue un role important dans l’immunite anti tumorale et a ete etudiee dans de nombreux cancers. Nous avons evalue la reponse immunitaire T CD4 Th1 grâce a la reponse T CD4 Th1 anti-telomerase (anti-TERT) chez des patients atteints de melanome de tous stades AJCC. La reponse anti-TERT des lymphocytes de patients atteints de melanome etait evaluee par ELISpot IFN-γ et comparee aux donnees clinico-biologiques des patients. Au total, 171 patients atteints de melanome etaient inclus et 156 d’entre eux avaient une evaluation de la reponse anti-TERT disponible. Une reponse anti-TERT etait retrouvee chez 55 % des patients. La reponse anti-TERT etait mo…
Inflammatory and immunological profile in COPD secondary to organic dust exposure.
2021
Inflammatory response in patients with COPD secondary to organic dust exposure (OD-COPD) is poorly understood. We therefore aimed to characterize inflammatory and immune profile from peripheral blood mononuclear cells (PBMC) in a group of patients with mild-to-moderate COPD secondary to organic dust exposure (OD-COPD), tobacco smoking (T-COPD), or both. We compared T, B and NK cells distribution and inflammatory (TNF-α, Il-1β, IL-6), type 1 (IFN-γ), type 2 (IL-4, IL-13) and type 3 (IL-17) immunity related cytokines at baseline, and after stimulation with LPS, flagellin and CD3/CD28 beads in all COPD groups. OD-COPD displayed significantly lower NK cells and CD8+ T cells compared with contro…
