Circulating calprotectin - Promising inflammation biomarker 

Calprotectin (S100A8/A9 or MRP8/14) is a promising biomarker for neutrophil activation and inflammation in multiple infections and non-infections inflammatory conditions. Its fast increase in inflammation enables an early and sensitive detection of inflammation and risk stratification.1 

If you want to learn more about this novel biomarker, please visit Gentian Diagnostic at booth #3503.

Calprotectin (S100A8/A9) in inflammatory rheumatic diseases (IRD)

Early detection of inflammation

Calprotectin, a heterodimer composed of two calcium-binding proteins (S100A8/A9 or MRP8/14), is part of the S100 protein family and is abundantly expressed by white blood cells, particularly neutrophils. Large amounts of stored calprotectin are released from neutrophils during inflammation. This direct and fast upregulation in inflammation makes calprotectin a highly sensitive and early biomarker.

The concentrations of circulating calprotectin correspond to the degree of inflammation. Indications for its use have been reported in both infectious and non-infectious inflammatory conditions.1

A sensitive biomarker for disease activity

Calprotectin is emerging as valuable biomarker in several chronic inflammatory conditions, including rheumatic diseases like Rheumatoid Arthritis, Juvenile Idiopathic Arthritis and Still’s Disease. Locally released calprotectin enters the systemic circulation where it can be measured in serum and plasma, at levels proportional to joint inflammatory activity.2,3

  • Direct marker of inflammatory activity
  • Detect low grade and subclinical inflammation activity
  • Monitoring of treatment and remission
  • Risk marker for disease flares

Recommended in clinical guidelines by ACR and EULAR/PReS

Both the American College of Rheumatology (ACR) and the European Alliance of Associations for Rheumatology (EULAR) in collaboration with the Paediatric Rheumatology European Society (PReS) have highlighted calprotectin as one of the new biomarkers strongly recommended in managing rheumatic diseases.

Namely, calprotectin (S100 protein as inflammatory marker) has been recommended in two first guidelines, regarding the diagnosis of Still’s disease (formerly known as systemic JIA and adult-onset Still’s disease) and the clinical workup up of IL-1 mediated autoinflammatory disease.
