Calprotectin represents an interesting peptide known to be involved in the pathophysiology of various inflammatory processes. Being secreted from activated neutrophils and monocytes under various conditions, it can also be found in the extracellular fluids and serve as a biomarker of ongoing inflammation, which property is currently used in the monitoring of inflammatory bowel diseases. ⋯ We assume that calprotectin may represent a useful marker in predicting the course of atherosclerotic process, coronary artery disease and acute coronary syndromes. Our review is focused on the importance of calprotectin in the diagnosis and prognostic stratification in the field of cardiometabolic risk.

ReviewDominance of the strongest: inflammatory cytokines versus glucocorticoids.
Pro-inflammatory cytokines are involved in the pathogenesis of many inflammatory diseases, and the excessive expression of many of them is normally counteracted by glucocorticoids (GCs), which are steroids that bind to the glucocorticoid receptor (GR). Hence, GCs are potent inhibitors of inflammation, and they are widely used to treat inflammatory diseases, such as asthma, rheumatoid arthritis and inflammatory bowel disease. However, despite the success of GC therapy, many patients show some degree of GC unresponsiveness, called GC resistance (GCR). ⋯ Treatment of inflammatory diseases with GCs is successful when GCs dominate. But when cytokines overrule the anti-inflammatory actions of GCs, patients become GC insensitive. New insights into the molecular mechanisms of GR-mediated actions and GCR are needed for the design of more effective GC-based therapies.
