Objective: A retrospective
investigation was made in a university hospital setting of the distribution of
Candida infections in terms of species, different clinical features of
infections, risk factors for candidemia caused by these fungi and their
antifungal susceptibilities.
Method: This study was
conducted between January 1st 2014 and December 31st 2017.
Patients included in the study were those diagnosed with candida infection as a
result of candida species, isolated from at least one clinical sample of those
taken from hospitalized patients, including blood, urine and other clinical
samples, and who were then administered antifungal therapy. The identification
of candida species was performed using Matrix-Assisted Laser
Desorption/Ionization Time-of-Mass Spectrometry (MALDI-TOF MS).
Results: During the study period, the candida
infection rate was found to be 5.86% in the 2760 episodes of infection and the
incidence of candida infection was found to be 0.35 in 1000 bed days. The most
common infection site for candida was the urinary tract (61.1%), followed by the
blood-stream (31.5%). In 66% of all candida infections, Candida albicans was defined as the causative agent. The distribution
of Candida glabrata, Candida tropicalis, Candida parapsilosis, Candida
lusiteniae, Candida krusei and Candida kefyr were determined as 9.9%,
9.3%, 4.9%, 2.5%, 1.9% and 1.2%, respectively. The sensitivity to fluconazole
and amphotericin B was determined as 97.2% and 99.1% in the C. albicans isolates, respectively. The sensitivity ratios for both
fluconazole and amphotericin B were determined as 78.2% in the non-albicans
strains. Multivariate logistic regression analysis showed that total parenteral nutrition (TPN) [Odds ratio (OR)
3.69, 95% Confidence interval, 1.595-8.570; p=0.002] was an independent risk
factor for candidemia in patients with candida infection.
Conclusions: C. albicans
were the most encountered species in candida infections in our hospital. TPN was determined as an independent risk factor
for the development of candidemia. Determinations of the species distribution
of fungal infections and the antifungal sensitivity are important for the
selection of effective treatment.
