Antifungal Susceptibility and Risk Factors in Patients with Candidemia.
OBJECTIVE
This study aimed to investigate the antifungal susceptibility, typology, and risk factors of candidemia among adult and pediatric inpatients at a university hospital.


METHODS
A case-control study was designed, and data collected between December 2013 and December 2014 were retrospectively evaluated. The case group consisted of patients with candidemia. The control group was selected from the inpatients that did not develop candidemia but were admitted in the same clinic and during the same period as the candidemia group. The diagnosis of candidemia was based on a compatible clinical picture and positive blood culture of Candida spp. The demographic characteristics, sequential organ failure assessment (SOFA) scores, comorbidities, use of invasive devices, antibiotics administered, and duration of antibiotic uses were compared between both the groups.


RESULTS
Out of the 84 patients, 42 (50%) were included in the case group, and the remaining 42 (50%) were included in the control group. Out of all the patients, 31 (36.9%) were female, and 53 (63.1%) were male. When the clinical findings of the case and control groups were compared, the prevalence of nosocomial infections, sepsis, candiduria, and fever was statistically significantly higher in the case group. Among the isolated group in the study, 22 (52.4%) were identified as C. albicans, while the others were non-albicans Candida strains. The C. albicans strain (4.5%) was resistant to fluconazole, while 7 among the non-albicans Candida strains (35%) were resistant to fluconazole. In the case group, abdominal surgery, CVP catheter presence, TPN, endotracheal intubation, frequency of blood transfusion, and SOFA scores were significantly higher than the control groups. The logistic regression test demonstrated that TPN and blood transfusion are the most important risk factors for candidemia (OR=8.14 and OR=5.96, respectively).


CONCLUSIONS
The invasive Candida infections continue to be a major health problem in Turkey and in our hospital. Particularly, it was observed that it is important to perform invasive procedures, antibiotic administration and parenteral nutrition carefully in patients hospitalized in the ICU.
