We have shown that benznidazole (BZL), a drug used to treat Chagas disease, markedly reduced the production of pro-inflammatory cytokines and NO-derived metabolites in experimentally –infected rats. Treatment with BZL exerted beneficial effects in a model of inflammation-based pathology like murine experimental endotoxemia. Based on these findings, we wished to ascertain the effect of BZL in a closer situation to sepsis: the cecal ligation and puncture (CLP) model in C57BL/6 mice. We analyzed clinical course, survival, circulating levels of inflammation-related compounds (NO, tumor necrosis factor [TNF]-α), and bacteriemia. Recipients of BZL, 25 mg/kg, had an increased survival rate at 24 hours after CLP, showing a better clinical situation and a significant reduction of TNF-α levels and bacteriemia, with respect to the other groups. BZL failed to inhibit bacterial growth, suggesting that these effects may be partly caused by the immunomodulatory effects of BZL.
