Recent studies demonstrated that soluble urokinase plasminogen activator receptor (suPAR) is a valuable marker in the recognition of an inflammatory response. Ongoing inflammation leads to elevated plasma suPAR levels. We aimed to characterize plasma suPAR levels in ankylosing spondylitis (AS) patients compared to healthy individuals in order to reveal if suPAR could be used as a clinical marker of inflammation in AS. We measured plasma suPAR and C-reactive protein (CRP) levels as well as erythrocyte sedimentation rate (ESR) in 33 AS patients at various stages of disease duration and activity and 29 healthy controls. CRP and ESR values were higher in AS patients than in healthy individuals, while suPAR values were comparable (median [interquartile range]: 2.97 [2.57-3.80] ng/mL vs. 2.80 [2.06-3.42] ng/mL, P>0.05). In AS patients, a correlation was detected between BASDAI scores and CRP as well as ESR values but not suPAR levels (P=0.0005, r=0.57 and P=0.01, r=0.43, respectively). Unlike in many other inflammatory conditions, plasma suPAR levels do not reflect inflammation in AS. To assess the inflammatory status in AS, ESR and particularly CRP values are still more appropriate clinical markers. In line with earlier findings, our results indicate that, unlike suPAR, both of these markers are positively correlated with disease activity in AS.

The assessment of the general inflammatory condition of patients with autoimmune connective tissue disorders (ACTD) is a major challenge. The use of traditional inflammatory markers including CRP-levels and erythrocyte sedimentation rate (ESR) is limited by several preanalytical factors and their low specificities. Soluble urokinase plasminogen activator receptor (suPAR) is one of the novel candidate markers that is increasingly used in immune mediated disorders. In our studies we compared suPAR levels of patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and ankylosing spondylitis with those of healthy controls. suPAR provided valuable clinical information on disease activity in RA, SLE and SSc. We identified a subgroup of remitted RA patients, who presented still clinical symptoms of inflammatory activity which correlated to high plasma suPAR (while ESR and CRP were normal). In SLE we established specific suPAR cut-off values that support the discrimination between patients with high and those with moderate SLE activity. In patients with SSc suPAR correlated with objective measures of lung and other complications. In the majority of ACTDs including SLE, SSc or RA, suPAR is seemingly a good biomarker that would provide valuable clinical information. However, before the introduction of this novel parameter in laboratory repertoire important issues should be elucidated. These include the establishment of appropriate and disease specific cutoff values, clarification of interfering preanalytical values and underlying conditions and declaration of age- and gender-specific reference ranges.
