Fructose-1,6-bisphosphate reduces the mortality in Candida albicans bloodstream infection and prevents the septic-induced platelet decrease

Due to the fact that an increased number of patients have experienced bloodstream infections caused by Candida species and the high mortality of this infection, there is a need for a strategy to reduce this scenery. One possible strategy is the use of new drugs, such as fructose-1,6-bisphosphate (FBP), which is a high-energy glycolytic metabolite and has shown to have therapeutic effects in several pathological conditions such as ischemia, shock, toxic injuries, and bacterial sepsis. The aim of this manuscript was to determine the role of FBP in experimental Candida albicans bloodstream infection. We used mice that were divided into three experimental groups: sham (not induced), bloodstream infection (induced with intratracheal instillation of C. albicans) and FBP (bloodstream infection plus FBP 500 mg/kg i.p.). Blood was taken for assessment of complete hematological profile and cytokine assay (IL-6 and MCP-1). Results of the study demonstrated that mortality decreased significantly in groups that received FBP. All cytokine and hematological indexes of FBP group were similar to bloodstream infection group with exception of platelets count. FBP significantly prevented the decrease in platelets. Taken together, our results demonstrate that FBP prevented the mortality in C. albicans bloodstream infection.

The use of caspofungin in HIV-infected individuals

Fungal infections are a significant cause of HIV-related morbidity and mortality, particularly in the developing world, but also in countries with access to highly active antiretroviral therapy. New agents are essential to improve present efficacy rates, particularly in cases of drug resistance. Caspofungin is a new antifungal from the echinocandin class and is licensed for the treatment of candidal infections and as a second-line therapy for invasive aspergillosis. In this paper, the pharmacology, interaction and susceptibility data for this agent are reviewed and studies supporting the use of this agent in HIV-infected individuals are examined. Finally, evidence for the use of caspofungin for the treatment of Pneumocystis jiroveci pneumonia, an unlicensed indication, including a case series from our own unit is explored.
