Oral candidiasis is a common disease in cancer patients subject to chemotherapy. The aim of this study was to evaluate the risk factors of rising oral candidiasis incidence and to identify the Candida species isolated from oral lesions of cancer patients and their antifungal sensitivity.
A total of 645 patients with cancer were examined. Several species were isolated from specimens and identified by morphological and molecular methods. The susceptibility of isolates to amphotericin B, fluconazole, and nystatin was also investigated.
A total of 74 isolates of were recovered from oral cavity of 61 cancer patients with oral candidiasis. The isolates included ( = 56; 75.5%), ( = 4; 5.4%), ( = 5; 7%), ( = 7; 9.4%), and ( = 2; 2.7%). A total ( = 72; 98.65%) of isolates were susceptible to nystatin, ( = 58; 78.4%) of them were susceptible to fluconazole, and ( = 8; 10.8%) of susceptible dose-dependent isolates were specified, ( = 46; 62.16%) of isolates were susceptible to amphotericin B.
Finally, in addition to emphasis on topical nystatin application in the first stage of oral candidiasis in these patients, using alternative systemic drugs such as fluconazole and amphotericin B can be considered for the resistant candida isolates to nystatin.
口腔念珠菌病是癌症化疗患者的常见疾病。本研究旨在评估口腔念珠菌病发病率上升的危险因素,并鉴定从癌症患者口腔病变中分离出的念珠菌种类及其抗真菌敏感性。
共检查了645例癌症患者。从标本中分离出几种菌种,并通过形态学和分子方法进行鉴定。还研究了分离株对两性霉素B、氟康唑和制霉菌素的敏感性。
从61例患有口腔念珠菌病的癌症患者口腔中总共分离出74株念珠菌。分离株包括白色念珠菌(n = 56;75.5%)、热带念珠菌(n = 4;5.4%)、近平滑念珠菌(n = 5;7%)、光滑念珠菌(n = 7;9.4%)和季也蒙念珠菌(n = 2;2.7%)。总共72株(98.65%)分离株对制霉菌素敏感,其中58株(78.4%)对氟康唑敏感,8株(10.8%)敏感剂量依赖性分离株被明确,46株(62.16%)分离株对两性霉素B敏感。
最后,除了在这些患者口腔念珠菌病的第一阶段强调局部应用制霉菌素外,对于对制霉菌素耐药的念珠菌分离株,可以考虑使用氟康唑和两性霉素B等替代全身药物。
