Clinical TrialSequential combined treatment with allopurinol and benznidazole in the chronic phase of Trypanosoma cruzi infection: a pilot study.
Even though the use of combined drugs has been proved to be effective in other chronic infections, assessment of combined treatment of antiparasitic drugs in human Chagas' disease has not been performed. Herein, a pilot study was conducted to evaluate the tolerance and side effects of a sequential combined treatment of two antiparasitic drugs, allopurinol and benznidazole, in the chronic phase of Trypanosoma cruzi infection. ⋯ This pilot study shows that the combination of allopurinol and benznidazole induces significant modifications in T and B cell responses indicative of a reduction in parasite burden, and sustains the feasibility of administration of two antiparasitic drugs in the chronic phase of Chagas' disease.

Conversion of OXA-66 into OXA-82 in clinical Acinetobacter baumannii isolates and association with altered carbapenem susceptibility.
Three clinical Acinetobacter baumannii isolates (A-C) were isolated from three separate patients during an outbreak in a hospital in Krakow, Poland. Isolate A was recovered first and was susceptible to carbapenems, whereas isolates B and C were resistant. The aim of this study was to investigate the differences in carbapenem susceptibility in these outbreak-related isolates. ⋯ Carbapenem resistance in outbreak-related isolates was mediated by conversion of OXA-66 into OXA-82 and its subsequent overexpression. This further highlights the genome plasticity of A. baumannii, leading to carbapenem resistance.

Impact on hospital mortality of catheter removal and adequate antifungal therapy in Candida spp. bloodstream infections.
We set out to identify the prognostic factors in adult patients with Candida spp. bloodstream infection, assessing the impact on in-hospital mortality of catheter removal and adequacy of antifungal therapy. ⋯ Delay in catheter withdrawal and in administration of adequate antifungal therapy was associated with increased mortality in candidaemic patients. Catheter management did not influence the prognosis of secondary non-catheter-related candidaemia.

Risk factors for KPC-producing Klebsiella pneumoniae enteric colonization upon ICU admission.
To identify risk factors for KPC-producing Klebsiella pneumoniae (KPC-Kp) enteric colonization at intensive care unit (ICU) admission. Recently, the emergence and spread of KPC-producing Enterobacteriaceae in healthcare facilities has become an important issue. Understanding the extent of the reservoir in ICUs may be important for targeted intervention. ⋯ The high prevalence of KPC-Kp enteric carriage in ICU patients at admission dictates the importance of implementation of infection control measures and strict antibiotic policies prior to ICU transfer.
