The objective of this study was to characterize the epidemiology of candidemia in cancer patients in the city of Rio de Janeiro, Brazil. An 18-month survey of fungemia in patients with cancer was undertaken in three Hospitals in Rio de Janeiro. Forty-three episodes of candidemia were identified in 43 patients, 43 of which were episodes of candidemia; in ten case the strains were not available for further identification of species and were excluded from this analysis. The overall distribution of fungi causing fungemia was: Candida albicans (5), Candida tropicalis (16), Candida parapsilosis (6), Candida guilliermondii (4), Candida lusitaniae (1) and Candida stellatoidea (1). Antifungal prophylaxis had been administered before the episode of fungemia in only six patients (18.2%): oral itraconazole in three patients and oral nistatin, low dose intravenous amphotericin B and oral fluconazole in one patient each. There was no difference in the presence of risk factors, clinical characteristics or in the outcome between albicans and non-albicans species, nor between Candida tropicalis and other non-albicans species. There was a clear predominance of non-albicans species, regardless of the underlying disease, antifungal prophylaxis or the presence of neutropenia.
本研究的目的是描述巴西里约热内卢市癌症患者念珠菌血症的流行病学特征。在里约热内卢的三家医院对癌症患者进行了为期18个月的真菌血症调查。在43例患者中确定了43例念珠菌血症发作,其中43例为念珠菌血症发作;10例菌株无法进一步鉴定菌种,因此排除在本分析之外。引起真菌血症的真菌总体分布情况为:白色念珠菌(5例)、热带念珠菌(16例)、近平滑念珠菌(6例)、季也蒙念珠菌(4例)、葡萄牙念珠菌(1例)和星状念珠菌(1例)。仅6例患者(18.2%)在真菌血症发作前接受了抗真菌预防治疗:3例患者口服伊曲康唑,1例患者分别口服制霉菌素、低剂量静脉注射两性霉素B和口服氟康唑。白色念珠菌和非白色念珠菌菌种之间,以及热带念珠菌和其他非白色念珠菌菌种之间,在危险因素、临床特征或结局方面均无差异。无论潜在疾病、抗真菌预防治疗或中性粒细胞减少症的存在情况如何,非白色念珠菌菌种均明显占优势。
