ACTIVATE-2: A Double-Blind Randomized Trial of BCG Vaccination Against COVID-19 in Individuals at Risk.

In a recent study of our group with the acronym ACTIVATE, Bacillus Calmete-Guérin (BCG) vaccination reduced the occurrence of new infections compared to placebo vaccination in the elderly. Most benefit was found for respiratory infections. The ACTIVATE-2 study was launched to assess the efficacy of BCG vaccination against coronavirus disease 2019 (COVID-19).

Heparin Binding Protein for the Early Diagnosis and Prognosis of Sepsis in the Emergency Department: The Prompt Multicenter Study.

Background: The validation of new biomarkers for the diagnosis and risk stratification of patients with sepsis at an early point is essential for successful treatment. Recent publications prompted us to investigate of heparin binding protein (HBP) for the emergency department (ED) admissions.

Materials And Methods: In this multicenter, cross-sectional study, HBP and procalcitonin (PCT) were measured within the first hour upon admission to the ED in plasma samples of 371 patients with signs of infection.

A 29-mRNA host response test from blood accurately distinguishes bacterial and viral infections among emergency department patients.

Background: Whether or not to administer antibiotics is a common and challenging clinical decision in patients with suspected infections presenting to the emergency department (ED). We prospectively validate InSep, a 29-mRNA blood-based host response test for the prediction of bacterial and viral infections.

Methods: The PROMPT trial is a prospective, non-interventional, multi-center clinical study that enrolled 397 adult patients presenting to the ED with signs of acute infection and at least one vital sign change.

The adipokine vaspin is associated with decreased coronary in-stent restenosis in vivo and inhibits migration of human coronary smooth muscle cells in vitro.

Background: Percutaneous coronary intervention represents the most important treatment modality of coronary artery stenosis. In-stent restenosis (ISR) is still a limitation for the long-term outcome despite the introduction of drug eluting stents. It has been shown that adipokines directly influence vessel wall homeostasis by influencing the function of endothelial cells and arterial smooth muscle cells.

Progression into sepsis: an individualized process varying by the interaction of comorbidities with the underlying infection.

Background: Development of sepsis is a process with significant variation among individuals. The precise elements of this variation need to be defined. This study was designed to define the way in which comorbidities contribute to sepsis development.

Ambulatory cardiology network in Greece: Clinical and therapeutic implications in the outpatient setting. The TEVE-SSF study.

Background: Community based registries are particularly valuable tools to Preventive Cardiology as they summarize epidemiological data of ischemic heart disease risk factors, medications and lifestyle characteristics.

Methods: We enrolled 1191 patients, from an outpatient community based cardiology network, dedicated to cover medically, office based professionals. We recorded demographic and lifestyle characteristics, risk factors for ischemic heart disease, all clinical entities diagnosed and therapies which were prescribed for hypertension and lipid disorders specifically.

G-CSF Predicts Cardiovascular Events in Patients with Stable Coronary Artery Disease.

Granulocyte-colony-stimulating-factor (G-CSF) induces mobilization of progenitor cells but may also exert pro-inflammatory and pro-thrombotic effects. Treatment with recombinant G-CSF after acute myocardial infarction is currently under examination and has been associated with in-stent restenosis. However, it is not known whether plasma levels of endogenous G-CSF are also associated with an increased cardiovascular risk.

Monocyte subset distribution in patients with stable atherosclerosis and elevated levels of lipoprotein(a).

Background: Lipoprotein(a) (Lp(a)) is a proatherogenic plasma lipoprotein currently established as an independent risk factor for the development of atherosclerotic disease and as a predictor for acute thrombotic complications. In addition, Lp(a) is the major carrier of proinflammatory oxidized phospholipids (OxPL). Today, atherosclerosis is considered to be an inflammatory disease of the vessel wall in which monocytes and monocyte-derived macrophages are crucially involved.

Association of small dense LDL serum levels and circulating monocyte subsets in stable coronary artery disease.

Objective: Atherosclerosis is considered to be an inflammatory disease in which monocytes and monocyte-derived macrophages play a key role. Circulating monocytes can be divided into three distinct subtypes, namely in classical monocytes (CM; CD14++CD16-), intermediate monocytes (IM; CD14++CD16+) and non-classical monocytes (NCM; CD14+CD16++). Low density lipoprotein particles are heterogeneous in size and density, with small, dense LDL (sdLDL) crucially implicated in atherogenesis.

Small high-density lipoprotein is associated with monocyte subsets in stable coronary artery disease.

Objective: High-density lipoprotein (HDL) particles are heterogeneous in structure and function and the role of HDL subfractions in atherogenesis is not well understood. It has been suggested that small HDL may be dysfunctional in patients with coronary artery disease (CAD). Monocytes are considered to play a key role in atherosclerotic diseases.

Soluble ST2 and interleukin-33 levels in coronary artery disease: relation to disease activity and adverse outcome.

Objectives: ST2 is a receptor for interleukin (IL)-33. We investigated an association of soluble ST2 (sST2) and IL-33 serum levels with different clinical stages of coronary artery disease. We assessed the predictive value of sST2 and IL-33 in patients with stable angina, non-ST elevation myocardial infarction (NSTEMI) and ST elevation myocardial infarction (STEMI).

An increase of interleukin-33 serum levels after coronary stent implantation is associated with coronary in-stent restenosis.

The study aim was to determine the predictive value of interleukin (IL)-33, a recently described member of the IL-1 family of cytokines, for the development of in-stent restenosis (ISR). IL-33 serum levels were measured in 387 consecutive patients undergoing percutaneous coronary intervention (PCI) of whom 193 had stable angina, 93 non-ST elevation myocardial infarction (NSTEMI), and 101 ST-elevation MI (STEMI), respectively. Blood was taken directly before and 24h after stent implantation.

Glycoprotein 130 polymorphism predicts soluble glycoprotein 130 levels.

Objective: Interleukin-6 (IL-6) is a key cytokine in inflammatory diseases. It exerts its biological function via binding to a homodimer of its signal transducer glycoprotein 130 (gp130). Soluble gp130 (sgp130) is the natural inhibitor of IL-6 trans-signalling.

An increase of VEGF plasma levels is associated with restenosis of drug-eluting stents.

Aims: Drug-eluting stents (DES) reduce late lumen loss compared to bare metal stents but were not able to eradicate in-stent restenosis (ISR) fully. Vascular endothelial growth factor (VEGF) may inhibit late lumen loss through accelerated reendothelialisation, but may also promote neointima formation by proinflammatory effects. The aim of this study was to evaluate whether endogenous plasma levels of VEGF are associated with development of ISR after implantation of DES.

Premature myocardial infarction is associated with low serum levels of Wnt-1.

Objective: Besides its effects on glucose and lipid metabolism, the Wnt pathway has been increasingly implicated in the regulation of proliferation, migration and survival of vascular cells. In addition, defective Wnt signaling has been identified in a family with autosomal dominant early coronary artery disease. The aim of this study was to investigate whether premature coronary artery disease is associated with features of decreased Wnt signaling.

High soluble Fas and soluble Fas Ligand serum levels before stent implantation are protective against restenosis.

Percutaneous coronary intervention (PCI) represents the most important treatment of coronary artery stenosis today. But instent restenosis (ISR) is a limitation for the outcome. Fas and Fas Ligand have been implicated in apoptosis and vessel wall inflammation.

Oncostatin M-enhanced vascular endothelial growth factor expression in human vascular smooth muscle cells involves PI3K-, p38 MAPK-, Erk1/2- and STAT1/STAT3-dependent pathways and is attenuated by interferon-γ.

The pleiotropic cytokine oncostatin M (OSM), a member of the glycoprotein (gp)130 ligand family, plays a key role in inflammation and cardiovascular disease. As inflammation precedes and accompanies pathological angiogenesis, we investigated the effect of OSM and other gp130 ligands on vascular endothelial growth factor (VEGF) production in human vascular smooth muscle cells (SMC). Human coronary artery SMC (HCASMC) and human aortic SMC (HASMC) were treated with different gp130 ligands.

Association between smoking and presence of mycoplasma pneumoniae in circulating leukocytes.

Principles: The morbidity and mortality of infectious diseases due to smoking are not widely appreciated by physicians. However, cigarette smoking appears to be a major risk factor for respiratory tract and other systemic infections. Only limited data are available on the association between smoking and Mycoplasma (M) pneumoniae.

The complement component C5a is present in human coronary lesions in vivo and induces the expression of MMP-1 and MMP-9 in human macrophages in vitro.

The complement component C5a is formed during activation of the complement cascade and exerts chemotactic and proinflammatory effects. Macrophages, which are localized in the rupture-prone shoulder regions of coronary plaques, are thought to play a major role in plaque destabilization and rupture through the production of matrix metalloproteinases (MMPs). When human monocyte-derived macrophages were stimulated in vitro with C5a, MMP-1 and MMP-9 mRNA levels were significantly increased.

Heart rate variability in advanced chronic kidney disease with or without diabetes: midterm effects of the initiation of chronic haemodialysis therapy.

Background: Previous studies in different clinical settings have established heart rate variability (HRV) as a significant independent risk factor for higher mortality and cardiac death. The aim of this study was to examine the effect of chronic haemodialysis therapy on time- and frequency-domain parameters of HRV in diabetic and non-diabetic patients with chronic kidney disease (CKD).

Methods: We studied 25 patients with stage 4 CKD and type 2 diabetes mellitus (CKD4+DM), 25 patients with stage 4 CKD without diabetes (CKD4), 25 patients with type 2 diabetes mellitus (DM) and 25 healthy subjects (HS).

Increased restenosis rate after implantation of drug-eluting stents in patients with elevated serum activity of matrix metalloproteinase-2 and -9.

Objectives: Our aim was to test whether serum levels of matrix metalloproteinase (MMP)-2 and -9 are associated with the development of in-stent restenosis (ISR) after implantation of drug-eluting stents (DES).

Background: With the introduction of DES coronary ISR could be reduced dramatically. However, it still plays a significant role, particularly after treatment of multiple, complex lesions.
