Resumen

DIAZ, Natalia A.; FARINA, Javier; HERRERA, Jorge  y  EZCURRA, M. Cristina. Candidemia: characteristics in elderly patients. Rev. chil. infectol. [online]. 2020, vol.37, n.3, pp.288-294. ISSN 0716-1018.  http://dx.doi.org/10.4067/s0716-10182020000300288.

Background:

Candidemia is a nosocomial bloodstream infection and an important cause of comorbidity and mortality. Elderly patients present the highest rates of candidemia but data about this population is scarce.

Aims:

To describe characteristics of candidemia in elderly patients, to identify risk factors associated with mortality and to evaluate the usefulness of a predictive score.

Methods:

A retrospective observational study of candidemia in elderly patients from a tertiary care hospital was carried out. We analyzed all Candida bloodstream infections during an eight-year period in patients older than 60 years.

Results:

Fifty-nine episodes were included. Diabetes was the most frequent comorbidity. Most candidemia were catheter related infections (45%). Only 17% of patients had a Candida score > 2.5. Overall mortality at 48 hours was 20%, and at 15 days was 49%. Mortality-related factors were shock, assisted mechanical ventilation, thrombocytopenia, renal failure and leukocytosis (p range < 0.0001-0.006). On multivariate analysis septic shock was independently associated with mortality (HR 4.02 [CI 95% 1.18-13.72] p = 0.026).

Conclusions:

Nearly half of patients with candidemia died during the first fifteen days. Shock, assisted mechanical ventilation, thrombocytopenia, renal failure, and leukocytosis were factors associated with mortality. The predictive score was not useful in this population.
