Abstract

The prevalence of fungemia due to non-albicans Candida species is increasing currently. However, there is no reported case of fungemia due to Candida famata in a burn unit. This retrospective study was aimed to evaluate the clinical and laboratory characteristics and outcomes of seven burn patients with fungemia due to C. famata. The study included a total of 410 burn patients followed-up during January 2003-January 2006. Six of the patients (85.7%) were males and one was female (14.3%), with a mean age of 22.2 years. Mean total body surface area of the burns was 39.2% (24%-64%), flame being the most frequent cause of the burns (n= 4), followed by hot water (n= 2) and electroshock (n= 1). Six of the cases had central venous catheter and in 5 of these catheter-associated bacteremia had developed before the establishment of candidemia. Pseudomonas aeruginosa (n= 5) was the most frequent cause of bacteremia; Escherichia coil being isolated from a patient with urinary tract infection and methicillin-resistant Staphylococcus aureus from a patient with wound infection. All patients had received treatment with systemic antibiotics prior to the development of the C. famata episode. C. famata was detected from the blood cultures of the patients, however, the wound swabs were negative in terms of C. famata growth. The isolates were defined according to their negative germ tube test and their carbohydrate assimilation profile in API 20 C AUX (BioMerieux, France). Since the environmental cultures yielded negative results for C. famata, the infections were thought to be derived from cross contamination. Once a positive blood culture for C. famata was obtained, the catheter was removed, and treatment with liposomal amphotericin-B was implemented. Presence of a central venous catheter and prior antibiotic therapy seem to be the predisposing factors in the development of fungemia due to C. famata. Thus, when fungemia due to C. famata is established, central venous catheter should be removed and amphotericin-B therapy should be implemented promptly.

Özet

Günümüzde albikans dışı kandidalar ile gelişen fungemiler giderek artmaktadır. Buna karşın ulaşılabildiği kadarıyla, yanık ünitesinde Candida famata'ya bağlı fungemi olgusu literatürde bildirilmemiştir. Çalışmamızda Ocak 2003-0cak 2006 tarihleri arasında hastanemizin yanık ünitesinde izlenen 410 hastadan C.famata'ya bağlı fungemi gelişen 7 olgunun (6 erkek, 1 kadın; yaş ortalaması 22.2 yıl) retrospektif olarak değerlendirilmesi amaçlanmıştır. Ortalama yanık yüzey alanı %39.2 (%24-64) olan olgularda yanık nedenleri; alev yanığı (n= 4), sıcak su (n= 2) ve elektrik çarpması (n= 1) olarak izlenmiştir. Olguların 6'sında santral venöz kateter uygulaması mevcut olup, bunların da 5'inde kandidemi öncesi kateterle ilişkili bakteremi gelişmiştir. Kateterle ilişkili bakteremi etkeninin Pseudomonas aeruginosa (n= 5) olduğu saptanmış; ayrıca, üriner sistem enfeksiyonu olan bir hastadan Escherichia coli, yanık yarası enfeksiyonu olan bir hastadan da metisiline dirençli Staphylococcus aureus izole edilmiştir. Tüm olguların kandidemi epizodundan önce geniş spektrumlu antibiyotik tedavisi aldığı belirlenmiştir. C.famata, olguların kan kültürlerinden izole edilmiş, yanık yüzey sürüntü kültürlerinde saptanmamıştır, izolatların tanımlanması, negatif germ tüp testi ile birlikte API 20 C AUX (BioMerieux, France) sistemindeki karbonhidrat asimilasyon profiline göre yapılmıştır. Alınan çevre kültürlerinde C.famata tespit edilememiş, enfeksiyonların çapraz kontaminasyon sonucu ortaya çıktığı düşünülmüştür. Santral venöz kateteri bulunan olgularda kateter çekilerek tüm hastalara lipozomal amfoterisin B tedavisi başlanmıştır. Bir olgu kandidemi nedeni ile kaybedilirken diğer 6 olgu tedavi ile iyileşmiştir. Olgularımızda C.famata'ya bağlı fungemi gelişiminde, kateter varlığı ile birlikte geniş spektrumlu antibiyotik kullanımının önemli faktörler olduğu kanısına varılmıştır. Sonuçlarımıza göre, C.famata'ya bağlı fungemi gelişen olgularda, varsa santral venöz kateterin çıkarılmasının ve amfoterisin B tedavisi uygulamasının hastaların prognozu açısından faydalı olacağı düşünülmüştür.
