  Introducción. El objetivo del estudio es evaluar el impacto del tratamiento antifúngico en la mortalidad hospitalaria a los 7 y 30 días en pacientes con candidemia en un hospital terciario español.

  Métodos. Se realizó un estudio retrospectivo que incluyó los pacientes adultos no neutropénicos diagnosticados de candidemia en el Hospital Clínico Universitario entre 2007 y 2016.

  Se evaluaron 179 pacientes, se dividieron en grupo de supervivientes (n=92) y no supervivientes (n=87).

  Resultados. La mortalidad a 7 días fue 25,1% (45), a los 30 días 46,9% (84) y la hospitalaria 48,6% (87). El 40,8% no recibieron antifúngico (43,8% de supervivientes y 37,8% de no supervivientes; p=0,15). El 50,3% (90) recibieron tratamiento empírico. De los supervivientes el 19,6% y 47,8% se trataron con equinocandinas y fluconazol, respectivamente. De los no supervivientes el 31% recibió equinocandinas y el 47,1% fluconazol. La supervivencia a los 7 días fue significativamente mayor en los tratados (log-rank = 0.029), no hubo diferencias a los 30 días. Los factores asociados a mortalidad hospitalaria fueron edad (OR: 1.040), shock séptico (OR: 2.694) y ventilación mecánica> 48 h (OR: 2.812).

  Conclusión. Los pacientes tratados con antifúngicos (ya sean equinocandinas o fluconazol) tienen una tasa de mortalidad inferior a los 7 días que los no tratados, sin embargo no hallamos diferencias a los 30 días.

  Introduction. The objective of this study was to evaluate the impact of echinocandins and fluconazole) on mortality 7 and 30 days after candidemia onset and overall in-hospital mortality), in patients with candidemia at a Spanish tertiary hospital.

  Methods. A retrospective study was conducted that enrolled all non-neutropenic adult patients diagnosed with candidemia at Hospital Clínico Universitario de Valladolid between 2007 and 2016. A total of 179 patients were evaluated, they were divided into two sub-groups: surviving patients (n = 92) and non-surviving patients (n = 87).

  Results. The 7-day mortality was 25,1% (45), 30-day mortality was 46,9% (84), and overall in-hospital mortality was 48,6% (87). 40.8% of patients received no antifungal treatment (43.8% of surviving patients and 37.8% of non-surviving patients; p=0.15). A total of 106 (59.2%) patients were treated, of which 90 patients (50.3%) received empiric treatment. 19.6% and 47.8% of surviving patients were treated with echinocandins and fluconazole, respectively. By contrast, of non-surviving patients, 31.0% were treated with echinocandins and 47.1% received fluconazole. Survival for the first 7 days was significantly higher in treated with antifungal agents (log-rank = 0.029), however, there were not significant differences in 30-day survival. Factors linked to a significant increase in overall in-hospital mortality were age (OR 1.040), septic shock (OR 2.694) and need for mechanical ventilation > 48 h (OR 2.812).

  Conclusion. Patients who received antifungal treatment, regardless of whether they received fluconazole or echinocandins, had a significantly lower mortality rate after 7 days than untreated patients, although no significant differences in 30- day mortality were seen.
