Objectives: The aim of this study was to compare concentrations of soluble intercellular adhesion molecule (ICAM-1) and vascular cell adhesion molecule (VCAM-1) in patients with coronary artery disease and healthy control and to evaluate the usefulness of the inflammatory markers as predictors of adverse prognosis in patients with acute coronary syndromes (ACS).
Design And Methods: ELISA was used to measure sICAM-1 and sVCAM-1 levels in 75 patients with ACS, 36 patients with stable angina pectoris (SAP) and 25 healthy subjects. hsCRP was measured with immunoturbidimetric assay, cardiac troponin T-with electrochemiluminescence immunoassay.
Results: All soluble ICAM-1 and VCAM-1 significantly discriminated between patients with ACS and SAP (p=0.014 and 0.05, respectively) and control subjects (p<0.001 and 0.05). During the 6-month follow-up of the patients with ACS, there were 28 major cardiac events (37.3%). The odds ratio associated with the highest value of sVCAM-1 was 4.62 (95% CI 1.8-11.4, p=0.0009) without adjustment and remained significantly elevated after adjustment for cTnT (RR 3.93, 1.5-10, p=0.04) and hsCRP (RR 2.22, 0.8-5.7, p=0.05). In contrast, an elevated level of sICAM-1 was not associated with future coronary risk after adjustment for cTnT and hsCRP.
Conclusions: In patients with acute coronary syndromes, VCAM-1 serum levels powerfully predict an increased risk for subsequent cardiovascular events and extend the prognostic information gained from traditional biochemical markers.

The aberrant vascular response associated with tendon injury results in circulating immune cell infiltration and a chronic inflammatory feedback loop leading to poor healing outcomes. Studying this dysregulated tendon repair response in human pathophysiology has been historically challenging due to the reliance on animal models. To address this, our group developed the human tendon-on-a-chip (hToC) to model cellular interactions in the injured tendon microenvironment; however, this model lacked the key element of physiological flow in the vascular compartment.

Background And Aims: Endocan has been scarcely explored in COVID-19, especially regarding its modulation by veno-venous extracorporeal membrane oxygenation (VV-ECMO), hypertension or previous renin-angiotensin-aldosterone system (RAAS) inhibitors treatment. We compared endocan and other endotheliitis markers in hospitalized COVID-19 patients and assessed their modulation by VV-ECMO, hypertension and previous RAAS inhibitors treatment.
Material And Methods: Serum endocan, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and E-selectin were measured in "severe" (n = 27), "critically ill" (n = 17) and "critically ill on VV-ECMO" (n = 17) COVID-19 patients at admission, days 3-4, 5-8 and weekly thereafter, and in controls (n = 23) at a single time point.

Upon exposure to inflammatory stimuli including TNF-α, endothelial cells are activated leading to the adhesion of monocytes to their surface. These events are involved in the pathophysiology of atherosclerosis. Since TNF-α activates the NF-κB pathway, which contributes to atherosclerosis, targeting this signaling pathway may help prevent the risk of developing the disease.

The protease, a disintegrin and metalloproteinase with thrombospondin type 1 motif member 13 (ADAMTS13), known to cleave only the von Willebrand factor (VWF), has powerful regulatory effects on microvascular platelet adhesion, thrombosis, inflammation, and endothelial dysfunction. We study the protection against diabetes-induced retinal injury in experimental rats by supplementation with recombinant ADAMTS13. We compare human epiretinal membranes and vitreous samples from nondiabetic subjects and patients with proliferative diabetic retinopathy (PDR) and extend in vitro analyses with the use of various immunodetection and spectrofluorimetric methods on rat retina and human retinal glial and endothelial cell cultures.

The therapeutic effects of probiotics in patients with traumatic brain injury (TBI) remain unclear. This study aimed to investigate the effects of probiotic supplementation on cell adhesion molecules, oxidative stress, and antioxidant parameters in TBI patients. This randomized, double-blind, placebo-controlled trial included 46 TBI patients who were randomly assigned to receive either a probiotic supplement (n = 23) or a placebo (n = 23) for 14 days.
