Background

The purpose of this study was to establish species distribution of Candida isolates from pediatric patients in Istanbul, Turkey, and to determine risk factors associated with nosocomial Candida infections.

Methods

This study was conducted between June 2013 and June 2014 by participation of 7 medical centers in Istanbul. Candida spp strains isolated from the clinical specimens of pediatric patients were included. Clinical features were recorded on a standardized data collection sheet.

Results

A total of 134 systemic Candida infections were identified in 134 patients. The patients were admitted in pediatric and neonatal intensive care units (41.8% and 9.7%, respectively) and in pediatric wards (48.5%). Candida albicans was the most prevalent species (47%), followed by Candida parapsilosis (13.4%), Candida tropicalis (8.2%), Candida glabrata (4.5%), Candida lusitaniae (3.7%), Candida kefyr (2.2%), Candida guilliermondii (1.5%), Candida dubliniensis (0.7%), and Candida krusei (0.7%). Types of Candida infections were candidemia (50.7%), urinary tract infection (33.6%), surgical site infection (4.5%), central nervous system infection (3.7%), catheter infection (3.7%), and intra-abdominal infection (3.7%). In multivariate analysis, younger age (1-24 months) and detection of non-albicans Candida spp was found to be risk factors associated with candidemia (P = 0.040; odds ratio [OR], 4.1; 95% confidence interval [CI], 1.06-15.86; and P = 0.02; OR, 2.4; 95% CI, 1.10-5.53, respectively).

Conclusions

This study provides an update for the epidemiology of nosocomial Candida infections in Istanbul, which is important for the management of patients and implementation of appropriate infection control measures.

Patients

The study was conducted in 7 pediatric departments of tertiary care teaching hospitals in Istanbul: (1) Istanbul University Istanbul Medical Faculty (93 beds), (2) Sisli Etfal Training and Research Hospital (128 beds), (3) Bezmialem Vakif University (65 beds), (4) Kanuni Sultan Suleyman Education and Research Hospital (96 beds), (5) Marmara University Medical Faculty (100 beds), (6) Istanbul University Cerrahpasa Medical Faculty (102 beds), and (7) Okmeydani Training and Research Hospital (90

Results

In the study period, a total of 134 nosocomial candidiasis episodes were identified in 134 patients. The overall incidence of nosocomial candidiasis for all institutions included in the study was found to be 5.6 per 1,000 admissions and for nosocomial candidemia it was 2.9 per 1,000 admissions. Of the study patients, 56 (41.8%) were women and 78 (58.2%) were men. The age range was ≤1 month to 16.7 years, with a median value of 11 months. Eighteen patients were ≤1 month old (13.4%), 68 patients

Discussion

In this study, we present a comprehensive description of nosocomial Candida infections in Istanbul, Turkey, between June 2013 and June 2014. The rate of Candida infections (5.6 per 1,000 admissions) and the rate of candidemia (2.9 per 1,000 admissions) in our population was comparable with other studies.12, 14, 15 There are also other studies reporting lower incidence rates.16, 17 Comparisons are problematic because nosocomial Candida infection rates may differ between different centers,

Conclusions

This study provides an updated circumstantial data on all systemic candidiasis infections in a heterogeneous pediatric population throughout Istanbul, the biggest city of Turkey. Inclusion of all pediatric ages, all hospital settings, and all systemic candidiasis episodes, instead of only high-risk groups and only episodes of candidemia, gives this study the ability to reflect on the big picture of nosocomial candidiasis. This showed us potential risk of candidiasis in all hospital settings and

      Rarely, C. pelliculosa, C. lusitaniae, C. palmioleophila, C. lipolytica, and C. pulcherrima were also identified in this series. The distribution of these uncommon Candida species in this study is different from the findings of previous studies.19–21 In the global investigation based on the SENTRY Antimicrobial Surveillance Program,21 among a total of 1354 Candida bloodstream infections, 50 (3.7%) were identified as miscellaneous species, including C. dubliniensis (16 isolates), C. guilliermondii (eight isolates), C. kefyr (six isolates), C. famata (three isolates), C. lipolytica (three isolates), C. rugosa (two isolates), C. sake (two isolates), C. pelliculosa (two isolates), and one isolate each of C. lambica, C. utilis, C. haemulonii, C. norvegensis, and C. inconspicua.
