Cardiovascular risk assessment beyond Systemic Coronary Risk Estimation: A role for organ damage markers

2012

BACKGROUND: Cardiovascular risk assessment in the clinical practice is mostly based on risk charts, such as Framingham risk score and Systemic Coronary Risk Estimation (SCORE). These enable clinicians to estimate the impact of cardiovascular risk factors and assess individual cardiovascular risk profile. Risk charts, however, do not take into account subclinical organ damage, which exerts independent influence on risk and may amplify the estimated risk profile. Inclusion of organ damage markers in the assessment may thus contribute to improve this process. OBJECTIVE: Our aim was to evaluate the influence of implementation of SCORE charts with widely available indexes of organ damage, with t…

Dynamics of complement activation in aHUS and how to monitor eculizumab therapy.

2014

Atypical hemolytic-uremic syndrome (aHUS) is associated with genetic complement abnormalities/anti–complement factor H antibodies, which paved the way to treatment with eculizumab. We studied 44 aHUS patients and their relatives to (1) test new assays of complement activation, (2) verify whether such abnormality occurs also in unaffected mutation carriers, and (3) search for a tool for eculizumab titration. An abnormal circulating complement profile (low C3, high C5a, or SC5b-9) was found in 47% to 64% of patients, irrespective of disease phase. Acute aHUS serum, but not serum from remission, caused wider C3 and C5b-9 deposits than control serum on unstimulated human microvascular endotheli…

The switch from proteasome to immunoproteasome is increased in circulating cells of patients with fast progressive immunoglobulin A nephropathy and a…

2021

  The proteasome to immunoproteasome (iPS) switch consists of β1, β2 and β5 subunit replacement by low molecular weight protein 2 (LMP2), LMP7 and multicatalytic endopeptidase-like complex-1 (MECL1) subunits, resulting in a more efficient peptide preparation for major histocompatibility complex 1 (MHC-I) presentation. It is activated by toll-like receptor (TLR) agonists and interferons and may also be influenced by genetic variation. In a previous study we found an iPS upregulation in peripheral cells of patients with immunoglobulin A nephropathy (IgAN). We aimed to investigate in 157 IgAN patients enrolled through the multinational Validation Study of the Oxford Classification of IgAN (VAL…

CKD NUTRITION, INFLAMMATION AND OXIDATIVE STRESS

2014

Introduction and Aims: Serum p-cresyl sulfate associates with cardiovascular disease in patients at different stages of chronic kidney disease. p-Cresyl sulfate concentrations are determined by intestinal uptake of p-cresol, human metabolism to p-cresyl sulfate and renal clearance. Whether intestinal uptake of p-cresol itself is associated with cardiovascular disease in patients with renal disease has not been studied to date. Methods: We performed a prospective study in patients with chronic kidney disease stage 1-5 (clinicaltrials.gov NCT00441623). Intestinal uptake of p-cresol, under steady state conditions, was estimated from 24h urinary excretion of p-cresyl sulfate. Primary endpoint w…
