- OBJECTIVE : To investigate how levels of the soluble urokinase plasminogen activator receptor (suPAR) and erythrocyte sedimentation rate (ESR) correlate with disease activity and prognosis in pulmonary tuberculosis (PTB). DESIGN: This was a retrospective analysis of patients with active PTB (n = 500) in Gondar, Ethiopia, for whom the suPAR (n = 301) and ESR (n = 330) were analysed at the start of treatment. Both biomarkers were available for 176 patients. Human immunodeficiency virus (HIV) status, chest X-ray (CXR) findings, classification according to the clinical TBscore and treatment outcome were all recorded. RESULTS : In a multivariable logistic regression analysis adjusted for age, sex and HIV status, surrogate markers of disease activity such as advanced CXR patterns correlated with increased levels of suPAR (adjusted OR [aOR] 8.24, Pamp;lt; 0.001) and of ESR (aOR 1.63, P = 0.030), whereas ESR only correlated significantly with a TBscore amp;gt;6 points. Increased levels of both suPAR and ESR were associated with unsuccessful treatment outcomes (aOR 2.93, P = 0.013; aOR 2.52, P = 0.025). The highest quartile of suPAR (aOR 13.3, P = 0.029) but not ESR levels correlated independently with increased mortality. CONCLUSION: SuPAR and ESR levels correlate with disease activity in PTB; however, the clinical role of these potentially prognostic biomarkers needs to be verified in prospective studies.
