Candida spp. can lead to infections or even fungal sepsis particularly among immunocompromised individuals.
The aim of the present study was to analyze the presence of Candida spp. among patients subjected to orthotopic heart transplantation.
Oral rinses from 50 patients subjected to orthotopic heart transplantation, aged 13 to 70 years, 40 males and 10 females, were examined. Sex-age-oral conditions matched-control included 50 individuals who were not subjected to any kind of transplantation and were not immunocompromised for any other reason. Counts of yeasts were expressed as median values of logarithm of cfu/mL and were statistically compared by Mann-Whitney's test. The heart transplant and control groups were compared for the presence of Candida spp. by chi-square test (p<0.05).
The results showed statistically significant difference (p=0.001) in the prevalence of Candida spp. between the transplantation and control groups. Counts of yeasts (cfu/mL) in the transplanted group were significantly higher than in the control group (p=0.005). Candida albicans was the most prevalent species isolated from both groups.
It was concluded that Candida yeast counts were higher in the heart transplant recipients than in the controls. There was higher variation of Candida species among the heart transplant patients and the most frequently isolated samples were: Candida albicans, Candida glabrata and Candida tropicalis. Isolates of Candida dubliniensis was not found in either of the groups.
念珠菌属可导致感染,甚至真菌性败血症,尤其是在免疫功能低下的人群中。
本研究旨在分析原位心脏移植患者中念珠菌属的存在情况。
对 50 例年龄在 13 至 70 岁、男性 40 例、女性 10 例的原位心脏移植患者的口腔冲洗液进行了检查。选择了 50 名未接受任何移植且无其他原因免疫功能低下的患者作为性别年龄口腔条件匹配的对照组。酵母计数表示为 cfu/mL 的对数中位数,并通过曼-惠特尼检验进行统计学比较。通过卡方检验(p<0.05)比较心脏移植组和对照组中念珠菌属的存在情况。
结果显示,移植组和对照组之间念珠菌属的流行率存在统计学显著差异(p=0.001)。移植组的酵母计数(cfu/mL)明显高于对照组(p=0.005)。两组均分离出白念珠菌,为最常见的分离株。
心脏移植受者的酵母计数高于对照组。心脏移植患者的念珠菌种类变异较大,最常分离到的样本为:白念珠菌、光滑念珠菌和热带念珠菌。两组均未分离到假热带念珠菌。
