Abstract

Candida species are the most important causes of nosocomial fungal infection. Candida albicans remains the most prevalent yeast isolated from blood cultures; however, an increase in the proportion of candida bloodstream isolates due to non-albicans species has been reported. In this study, the specimens of neutropenic patients with hematologic malignancies were analyzed to evaluate the colonization and infection by Candida species. Forty febrile neutropenic patients hospitalized in the Mersin University Hospital between March 2003 and December 2005 were evaluated. Of these patients 19 were female, 21 were male and the mean age was 53.62 ± 18.42 years. The underlying diseases in all patients were hematological malignancies. All patients were in the high risk group during attacks according to MASCC scoring system. A total of 88 yeast strains were identified in terms of fermentation and assimilation reactions with API 32C and conventional methods: 39 C. albicans (44.3%) and 49 (%55.7) non-albicans species including 17 (19.3%) C. tropicalis, 12 (13.7%) C. parapsilosis, 10 (11.4%) C. glabrata, 6 (6.8%) C. kefyr, and 4 (4.5%) C. krusei. The most frequently isolated species from blood cultures was C. parapsilosis (41.3%). Thirty-two patients had empiric antifungal therapy for an average of 15.92±9.71 days. In conclusion, a high isolation rate of non-albicans Candida species (55.7%) was determined. This will be a guide for the choice of empiric antifungal therapy as well as determining the causes of increasing rate of non-albicans Candida isolation.

Özet

Candida türleri nozokomiyal mantar infeksiyonlarına sık neden olan önemli etkenlerdir. Kan kültürlerinden izole edilen mayaların önemli bir kısmını hala C. albicans oluşturmakla birlikte non-albicans türlerde artış olduğu gözlenmektedir. Bu çalışmada, hematolojik maligniteli nötropenik hastaların çeşitli klinik örneklerinden kolonizasyon ya da infeksiyon etkeni olarak izole edilen Candida türleri değerlendirildi. Mart 2003-Aralık 2005 tarihleri arasında Mersin Üniversitesi Hastanesi'nde yatan kırk nötropenik ateşli olgunun 19'u kadın, 21'i erkekti ve yaş ortalamaları 53.62 ± 18.42 idi. Tüm hastalarda altta yatan hastalık hematolojik malignensiydi. MASCC skorlama sistemine göre tüm hastalar yüksek riskli grupta yer almaktaydı. Toplam 88 maya suşu konvansiyonel ve API 32 C asimilasyon yöntemleriyle tür düzeyinde tanımlandı. Kökenlerin 39'u (%44.3) C. albicans, 49'u (%55.7) non-albicans C. idi (17 C. tropicalis (%19.3), 12 C. parapsilosis (%13.7), 10 C. glabrata (%11.4), altı C. kefyr (%6.8), dört C. krusei (%4.5)). Candida parapsilosis kan kültürlerinden sıklıkla izole edilen türdü (%41.3). Otuz iki hastaya 15.92±9.71 gün süreyle ampirik antifungal tedavi uygulandı. Sonuç olarak, nötropenik ateşli olgularda non-albicans kandida oranının arttığı (%55.7) saptandı. Bu artış ampirik tedavide antifungal seçiminde yol gösterici olmasının yanı sıra, nedenlerinin irdelenmesi gereğini de gündeme getirmiştir.
