Aim:
The infections caused by Candida species are important causes of mortality in
intensive care unit (ICU) patients. In this study, we aimed to determine the
distributions of Candida species and the susceptibilities of these organisms to
amphotericin B, flucanazole, flucytosine, and varicozanole retrospectively,
which were isolated from various clinical samples of ICU patients at Etlik
Education and Research Hospital.
Materials
and methods: In this study, a total of 51 Candida
species were included that were isolated from urine (n=46, 90%), blood (n=2,
4%), bronchoalveolar lavage fluid (n=2, 4%) and wound cultures (n=1, 2%) of ICU
patients between January 2011 and January 2012. Candida species were identified
by germ tube test and VITEK 2 Compact System (BioMerieux, France) automatized
identification system and their antifungal susceptibilities were determined.
Results: Of these 51 Candida species; 26 (51%) were C. albicans, 7 (14%) were C. tropicalis,
5 (10%) were C. parapsilosis, 4 (8%) were C. glabrata, 3 (6%) were C.
lusitaniae, 3 (6%) were C. Krusei, 2 (4%) were C. famata and 1 (2%) was C.
kefyr. Forty-nine (98%) Candida species
were investigated for antifungal susceptibility. For flucytosine, 47 (95.9%)
species were sensitive whereas 2
C. krusei species were moderately sensitive. For
fluconazole, 42 species (85.7%) were sensitive, 6 species (3 C. krusei, 3 C. glabrata) were resistant, and 1
species (C. galibrata) was moderately
sensitive. For voricanazole, 48 species (98%) were sensitive, and 1 C. glabrata species was resistant. For
amphotericin B, 45 species (91.8%) were sensitive and 4 species (2 C. krusei, 2 C. glabrata) were moderately sensitive.
Conclusion:
In intensive care unit patients, identification of Candida species and
determination of antifungal susceptibilities is necessary for planning both
empirical and agent specific antifungal therapy.
Amaç: Candida türlerine bağlı infeksiyonlar yoğun bakım
ünitelerinde yatan hastalarda mortalitenin önemli bir nedenidir. Bu çalışmada,
Etlik İhtisas Eğitim ve Araştırma Hastanesi Yoğun Bakım Ünitesinde yatan
hastaların çeşitli klinik örneklerinden izole edilen Candida türlerinin
dağılımının ve amfoterisin B, flukonazol, flusitozin ve vorikonazol
duyarlılıklarının retrospektif olarak belirlenmesi amaçlandı.
Gereç-Yöntem: Çalışmada Ocak 2011- Ocak 2012 tarihleri
arasında Etlik İhtisas Eğitim ve Araştırma Hastanesi Yoğun Bakım Ünitesinde
yatan hastaların 46 idrar (90.2), 2 kan (%4 ), 2 (%4)bronkoalveoler lavaj
sıvısı ve 1 (%2) yara kültüründen izole edilen toplam 51 Candida suşu çalışmaya
alındı. Candida suşları germ tüp testi ve VITEK 2 Compact System
(BioMerieux,Fransa) otomatize identifikasyon sistemi ile tanımlandı ve
antifungal duyarlılıkları belirlendi.
Bulgular: Toplam 51 Candida suşunun
26 (%51)’sı C.albicans, 7 (%14)’si C. tropicalis, 5 (%10 )’i C. parapsilosis, 4 (%8)’ü C.glabrata, 3 (%6)’ü C. lusitaniae, 3 (%6)’ü C. krusei, 2(%4)’si C. famata ve 1 (%2)’i C.kefyr
olarak belirlendi. Kırkdokuz (%96) Candida suşunda antifungal duyarlılık
araştırıldı. Flusitozin 47 suşta (%95.9) duyarlı iken, 2 tane C.krusei suşunda orta duyarlı idi.
Flukonazol 42 suşta (%85.7) duyarlı iken, 6 suşta dirençli (3’ü C. krusei, 3’ü C.glabrata ), 1 C.glabrata suşunda ise orta duyarlı idi.
Vorikonazol 48 suşta (%98) duyarlı iken, 1 C. glabrata suşunda dirençli idi.
Amfoterisin B 44 suşta (%90) duyarlı iken, 4 suşun (2’si C. krusei, 2’si C. glabrata)
orta duyarlı olduğu tespit edildi.
Sonuç: Yoğun bakım ünitesinde yatan
hastalarda Candida türlerinin sıklığının ve antifungal duyarlılıklarının
saptanması hem ampirik antifungal tedavinin planlanması hem de etkene spesifik
antifungal tedavinin belirlenmesi açısından gereklidir.
