Abstract

Objective: To evaluate the long pentraxin PTX3 in patients with severe leptospirosis and to compare the results with the widely used short pentraxin C-reactive protein and the pro-inflammatory cytokines IL-6 and IL-8. Methods: This observational cohort study was carried out in Semarang, Indonesia, where leptospirosis is endemic and mortality is high. Consecutive patients with severe leptospirosis were sampled on admission and during follow-up. Results: A total number of 52 patients entered the study, the mortality was 27%. Severe leptospirosis patient yielded elevated plasma PTX3 levels. PTX3 correlated with IL-8 and to a lesser extent with CRP and IL-6 levels. High levels of PTX3, IL-6 and IL-8 were associated with mortality (OR 5.6, 95%CI: 1.2-26; OR 3.2, 95%CI: 1.2-8.1; OR 6.5, 95%CI: 1.5-28). Moreover, PTX3 levels were associated with disease severity (OR 9.5; 95%CI: 2.9-45). This association was unique, since none of the other markers showed this relation. C-reactive protein was not able to differentiate the severe from the severest cases. Conclusions: The long pentraxin PTX3 is elevated in patients with severe leptospirosis and is associated with fatal disease and disease severity. PTX3 may be used as a marker to monitor disease severity in severe leptospirosis or predict outcome.
