Utility of the plasma level of suPAR in monitoring risk of mortality during TB treatment.
<h4>Objective</h4>To investigate whether changes in the plasma level of soluble urokinase plasminogen activator receptor (suPAR) can be used to monitor tuberculosis (TB) treatment efficacy.<h4>Design</h4>This prospective cohort study included 278 patients diagnosed with activ...

| Sumario: | <h4>Objective</h4>To investigate whether changes in the plasma level of soluble urokinase plasminogen activator receptor (suPAR) can be used to monitor tuberculosis (TB) treatment efficacy.<h4>Design</h4>This prospective cohort study included 278 patients diagnosed with active pulmonary TB and followed throughout the 8-month treatment period.<h4>Results</h4>Mortality during treatment was higher in the highest inclusion quartile of suPAR (23%) compared to the lowest three quartiles (7%), the risk ratio being 3.1 (95% CI 1.65-6.07). No association between early smear conversion and subsequent mortality or inclusion suPAR was observed. After 1 and 2 months of treatment, an increase in suPAR compared to at diagnosis was associated with a Mortality Rate Ratio (MRR) of 4.5 (95%CI: 1.45-14.1) and 2.1 (95%CI 0.62-6.82), respectively, for the remaining treatment period.<h4>Conclusions</h4>The present study confirmed that elevated suPAR level at time of initiation of TB treatment is associated with increased risk of mortality. Furthermore, increased suPAR levels after one month of treatment was associated with increased risk of mortality during the remaining 7-month treatment period. |
