Cardiac output (CO) monitoring is a valuable tool for the diagnosis and management of critically ill patients. In critical care setting, few studies have evaluated level agreement between CO estimated by transthoracic echocardiography (CO-TTE) that measured reference method, pulmonary artery catheter (CO-PAC). The objective present study was to evaluate precision accuracy CO-TTE relative CO-PAC ability track variations in CO, mechanically ventilated Thirty-eight patients fitted with PAC were...
Immunoreceptors can transduce either inhibitory or activatory signals depending on ligand avidity and phosphorylation status, which is modulated by the protein kinases Lyn Fyn. Here we show that Fyn control immune receptor signaling status. SHP-1 tyrosine 536 activates phosphatase promoting through immunoreceptor. By contrast, Fyn-dependent of serine 591 inactivates phosphatase, enabling immunoreceptor signaling. These signatures are relevant in vivo, as deficiency exacerbates nephritis...
Although kidney transplantation carries a survival benefit compared with dialysis, mortality, especially the first year after transplantation, is high in recipients older than 70. The aim of this study was to evaluate early death and graft failure, determine risk factors associated these events specific population.
Data from the PEXIVAS trial challenged role of plasma exchange (PLEX) in ANCA-associated vasculitides (AAV). We aimed to describe kidney biopsy patients with AAV treated PLEX, evaluate whether histopathologic findings could predict function, and identify which would most benefit PLEX.We performed a multicenter, retrospective study on 188 AKI PLEX 237 not PLEX. The primary outcome was mortality or KRT at 12 months (M12).No significant for found. To benefitting we developed model predicting...
<h3>Importance</h3> Older patients are underrepresented in studies of rituximab for the treatment antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis. Little is known about outcomes and adverse events associated with use therapy among 75 years older ANCA-associated <h3>Objective</h3> To examine vasculitis, specifically granulomatosis polyangiitis (GPA) or microscopic (MPA). <h3>Design, Setting, Participants</h3> This multicenter cohort study involved 93 vasculitis from 36...
Eosinophilic granulomatosis with polyangiitis (EGPA) is a systemic small-vessel vasculitis characterized by asthma, hypereosinophilia and ANCA positivity in 40% of patients. Renal involvement rare poorly described, leading to this renal biopsy-proven based study large EGPA cohort.We conducted retrospective multicentre including patients fulfilling the 1990 ACR criteria and/or 2012 revised Chapel Hill Consensus Conference for modified MIRRA trial, nephropathy.Sixty-three [27 women, median age...
Abstract Objectives Urticarial vasculitis (UV) is characterized by atypical urticarial lesions and leukocytoclastic vasculitis, sometimes with extracutaneous manifestations. First-line treatment based on colchicine, hydroxychloroquine, dapsone or low-dose glucocorticoids. In refractory forms, the use of biologics has been anecdotally described as potentially effective. We aimed to describe efficacy safety in patients UV. Methods conducted a retrospective European multicentre study including...
The risk of early death is particularly high in patients over the age 65 presenting with antineutrophil cytoplasmic antibody (ANCA)-associated renal vasculitis. We hypothesized that by combining disease severity markers, a comorbidity index and serious adverse event reports, we would be able to identify predictors one-year mortality this population.We performed multicentre, retrospective study nephrology internal medicine departments six tertiary hospitals northern France. A total 149...
Background IgG4-related kidney disease is a major manifestation of disease, systemic fibroinflammatory disorder. However, the clinical and prognostic kidney-related factors in patients with are insufficiently defined. Methods We conducted an observational cohort study using data from 35 sites two European countries. Clinical, biologic, imaging, histopathologic data; treatment modalities; outcomes were collected medical records. Logistic regression was performed to identify possible related...
Data for ANCA-associated vasculitis (AAV) patients requiring intensive care are scarce. We included 97 consecutive with acute AAV manifestations (new onset or relapsing disease), admitted to 18 units (ICUs) over a 10-year period (2002–2012). A group of 95 new disease, two nephrology departments manifestations, constituted the control group. In ICU group, predominantly showed granulomatosis polyangiitis and proteinase-3 ANCAs. Compared non-ICU comparable Birmingham activity score higher...
To examine whether the new urinary biomarkers TIMP2 and IGFBP7 can predict progression within 24 hours 72 from mild moderate (KDIGO 1 or 2) to severe 3) AKI in patients with septic shock. A prospective, multicenter observational study performed three French ICUs. The TIMP2∗IGFBP7 were analyzed at early phase (<6 hours) of admitted for shock AKI. Among 112 included, 45 (40%) progressed KDIGO 3 level after inclusion H24) 47 (42%) H72). median (baseline) higher group than KDIGO<3 H24 H72. All...
Background:Indoxyl sulfate (IS) is a protein-bound uremic toxin that known to be associated with the risk of cardiovascular (CV) disease and death in both predialysis dialysis patients. Data on levels toxins kidney transplant patients are scarce. The study's objective was evaluate IS relationship hard outcomes.Methods Results:In 311 patients, were measured immediately before transplantation (T0), 1 month (M1) 12 months (M12) afterwards. Over mean±standard deviation follow-up period 113±29...
High serum levels of gut-derived uremic toxins, especially p-cresyl sulfate (pCS), indoxyl (IS) and indole acetic acid (IAA), have been linked to adverse outcomes in patients with chronic kidney disease (CKD). Sevelamer carbonate could represent an interesting option limit the elevation toxins. The aim present study was evaluate adsorptive effect sevelamer on different protein-bound toxins or their precursors vitro, its impact pCS, IS IAA CKD stage 3b/4. For vitro experiments, IAA, p-cresol...
Background: Uremic toxins have emerged as potential mediators of morbidity and mortality in patients with chronic kidney disease (CKD). Indole-3-acetic acid (IAA, a tryptophan-derived uremic toxin) might be useful biomarker CKD. The objectives the present study were to (i) describe IAA concentrations cohort non-transplanted CKD transplanted CKD, (ii) investigate possible relationship between levels adverse outcomes two cohorts. Methods: Levels free total assayed prospective cohorts (140 311...
Activation of the complement system is involved in pathogenesis anti-glomerular basement membrane (anti-GBM) disease. Glomerular deposits 3 (C3) are often detected on kidney biopsies. The primary objective this study was to analyze prognostic value serum C3 level and presence glomerular patients with anti-GBM disease.We conducted a retrospective cohort 150 single-positive disease diagnosed between 1997 2017. Patients were categorized according (forming low (C3<1.23 g/L) high (C3≥1.23 groups)...
Background The severity and course of sepsis-associated acute kidney injury (SA-AKI) are correlated with the mortality rate. Early detection SA-AKI subphenotypes might facilitate rapid provision individualized care.
<h3>Background</h3> The PEXIVAS (Plasma exchange and glucocorticoids in severe antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis) trial showed that a reduced-dose glucocorticoid regimen (redGC) was non-inferior to standard-dose (standGC) with respect death or end-stage kidney disease (ESKD) patients ANCA-associated vasculitis (AAV). However, the primary endpoint did not include progression relapse, cyclophosphamide main induction therapy rituximab (RTX)-treated tended have...
