title: [Biomarkers for chronic inflammatory diseases].
abstract: Inflammatory disorders of childhood, such as juvenile idiopathic arthritis (JIA) and inflammatory bowel disease (IBD) are a challenge for laboratory diagnostics. Firstly, the classical inflammatory markers, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) often inadequately reflect disease activity but on the other hand there are few specific biomarkers that can be helpful in managing these diseases. Acute phase proteins reflect the systemic inflammatory response insufficiently as their increase is only the indirect result of local inflammatory processes. Modern inflammation diagnostics aim to reflect these local processes and to allow precise monitoring of disease activity. Experimental biomarkers, such as S100 proteins can detect subclinical inflammatory activity. In addition, established laboratory parameters exist for JIA [antinuclear antibodies (ANA), rheumatoid factor (RF), antibodies against cyclic citrullinated peptide (anti-CCP)] and for chronic IBD (fecal calprotectin) that are useful in the treatment of these diseases.
