Mortality of patients with end-stage renal disease tremendously exceeds that of the general population due to excess cardiovascular morbidity. Large middle-sized molecules (LMM) including pro-inflammatory cytokines are major drivers of uremic cardiovascular toxicity and cannot be removed sufficiently by conventional high-flux (HFL) hemodialysis. We tested the ability of plasma from 19 hemodialysis patients participating in a trial comparing HFL with high cut-off (HCO) membranes facilitating removal of LMM to induce calcification in mesenchymal stromal cells (MSC) functioning as vascular progenitors.

Factor H-related protein 1 (FHR-1) is a member of the factor H protein family, which is involved in regulating innate immune complement reactions. Genetic modification of the encoding gene, CFHR1 on human chromosome 1, is involved in diseases such as age-related macular degeneration, C3 glomerulopathy and atypical haemolytic uraemic syndrome, indicating an important role for FHR-1 in human health. Recent research data demonstrate that FHR-1 levels increase in IgA nephropathy and anti-neutrophilic cytoplasmic autoantibodies (ANCA) vasculitis and that FHR-1 induces strong inflammation in monocytes on necrotic-type surfaces, suggesting a complement-independent role.

Myocarditis and inflammatory cardiomyopathy: current evidence and future directions.

Nat Rev Cardiol

March 2021

Berlin Institute of Health Center for Regenerative Therapies (BCRT), Charité - University Medicine Berlin, Campus Virchow Clinic, Berlin, Germany.

Inflammatory cardiomyopathy, characterized by inflammatory cell infiltration into the myocardium and a high risk of deteriorating cardiac function, has a heterogeneous aetiology. Inflammatory cardiomyopathy is predominantly mediated by viral infection, but can also be induced by bacterial, protozoal or fungal infections as well as a wide variety of toxic substances and drugs and systemic immune-mediated diseases. Despite extensive research, inflammatory cardiomyopathy complicated by left ventricular dysfunction, heart failure or arrhythmia is associated with a poor prognosis.

July 2021

Department of Gastroenterology and Hepatology, Faculty of Medicine, and University Hospital Cologne, University of Cologne, Kerpener Str. 62, 50937, Cologne, Germany.

Non-alcoholic fatty liver DISEASE (NAFLD) is the most common chronic liver disease in Western countries and affects approximately 25% of the adult population. Since NAFLD is frequently associated with further metabolic comorbidities such as obesity, type 2 diabetes mellitus, or dyslipidemia, it is generally considered as the hepatic manifestation of the metabolic syndrome. In addition to its potential to cause liver-related morbidity and mortality, NAFLD is also associated with subclinical and clinical cardiovascular disease (CVD).
