Effect of leaving chronic oral foci untreated on infectious complications during intensive chemotherapy

BACKGROUND: Leukaemic patients receiving intensive chemotherapy and patients undergoing autologous stem-cell transplantation (ASCT) are routinely screened for oral foci of infection to reduce infectious complications that could occur during therapy. In this prospective study we assessed the effect of leaving chronic oral foci of infection untreated on the development of infectious complications in intensively treated haematological patients. METHODS: We included and prospectively evaluated all intensively treated leukaemic patients and patients undergoing ASCT who were referred to our medical centre between September 2012 and May 2014, and who matched the inclusion/exclusion criteria. Acute oral foci of infection were removed before chemotherapy or ASCT, whereas chronic oral foci were left untreated. RESULTS: In total 28 leukaemic and 35 ASCT patients were included. Acute oral foci of infection were found in 2 leukaemic (7%) and 2 ASCT patients (6%), and chronic oral foci of infection in 24 leukaemic (86%) and 22 ASCT patients (63%). Positive blood cultures with microorganisms potentially originating from the oral cavity occurred in 7 patients during treatment, but were uneventful on development of infectious complications. CONCLUSIONS: Our prospective study supports the hypothesis that chronic oral foci of infection can be left untreated as this does not increase infectious complications during intensive chemotherapy.British Journal of Cancer advance online publication, 22 March 2016; doi:10.1038/bjc.2016.60 www.bjcancer.com

Candidemia in non-ICU surgical wards: Comparison with medical wards

Candidemia acquired outside critical care or hematological areas has received much attention in recent years; however, data on candidemia in surgical departments are very scarce. Our objectives were to describe episodes of candidemia diagnosed in surgical wards and to compare them with episodes occurring in medical wards. We performed a post hoc analysis of a prospective, multicenter study implemented in Spain during 2010-2011 (CANDIPOP project). Of the 752 episodes of candidemia, 369 (49.1%) occurred in patients admitted to surgical wards (165, 21.9%) or medical wards (204, 27.2%). Clinical characteristics associated with surgical patients were solid tumor as underlying disease, recent surgery, indwelling CVC, and parenteral nutrition. Candidemia was more commonly related to a CVC in the surgical than in the medical wards. The CVC was removed more frequently and early management was more appropriate within 48 hours of blood sampling in the surgical patients. Overall, 30-day mortality in the surgical departments was significantly lower than in medical wards (37.7% vs. 15.8%, p<0.001). Multivariate analysis revealed admission to a surgical ward and appropriate early management of candidemia as factors independently associated with a better outcome. We found that approximately 50% of episodes of candidemia occurred in non-hematological patients outside the ICU and that clinical outcome was better in patients admitted to surgical wards than in those hospitalized in medical wards. These findings can be explained by the lower severity of underlying disease, prompt administration of antifungal therapy, and central venous catheter removal
