AB  - Objective. Increased levels of N-terminal pro-brain natriuretic peptide (NT-proBNP) are associated with cardiovascular morbidity and mortality. Inflammation may also affect levels of NT-proBNP. We investigated the relationship of NT-proBNP with inflammation, disease activity, disease severity, and progression of Takayasu arteritis (TA). Methods. Plasma levels of NT-proBNP were determined in 68 patients with TA and in 90 control subjects. Disease activity and disease severity in patients with TA were defined according to the National Institutes of Health and Ishikawa’s criteria, respectively. Results. NT-proBNP levels were higher in patients with active disease (915.0 ± 328.0 pmol/l) and patients in remission (618.2 ± 243.4 pmol/l) than in controls (427.2 ± 81.4 pmol/l) (p < 0.001). Patients with severe TA showed significantly higher NT-proBNP levels than those with mild-moderate TA (924.0 ± 332.4 pmol/l vs 653.8 ± 269.1 pmol/l; p = 0.001). In patients with longitudinal data, NT-proBNP levels at the active phase were significantly higher than those at the stable phase (944.1 ± 216.7 pmol/l vs 552.1 ± 178.2 pmol/l; p = 0.001). Inflammatory markers, including C-reactive protein, erythrocyte sedimentation rate, and white blood cell count, were independently associated with NT-proBNP levels after adjustment for other confounding factors (R2 adjusted = 0.307, p = 0.001). Conclusion. NT-proBNP levels were significantly increased in patients with active TA exhibiting complications. NT-proBNP levels were independently associated with inflammation. These results indicate that NT-proBNP may be a useful marker to assess the status, severity, and progression of TA.
