Fungal infections are still a relevant challenge for clinicians involved in the cure of patients with cancer. We retrospectively reviewed charts of hospitalized patients with haematological malignancies (HMs), in which a documented fungaemia was diagnosed between January 2011 and December 2015 at 28 adult and 6 paediatric Italian Hematology Departments.
During the study period, we recorded 215 fungal bloodstream infections (BSI). Microbiological analyses documented that BSI was due to moulds in 17 patients (8%) and yeasts in 198 patients (92%), being Candida spp identified in 174 patients (81%).
Mortality rates were 70% and 39% for mould and yeast infections, respectively. Infection was the main cause of death in 53% of the mould and 18% of the yeast groups. At the multivariate analysis, ECOG ≥ 2 and septic shock were significantly associated with increased mortality, and removal of central venous catheter (CVC) survival was found to be protective. When considering patients with candidemia only, ECOG ≥ 2 and removal of CVC were statistically associated with overall mortality.
Although candidemia represents a group of BSI with a good prognosis, its risk factors largely overlap with those identified for all fungaemias, even though the candidemia-related mortality is lower when compared to other fungal BSI. Management of fungal BSI is still a complex issue, in which both patients and disease characteristics should be focused to address a personalized approach.
真菌感染仍然是参与癌症患者治疗的临床医生面临的一个相关挑战。我们回顾性分析了 2011 年 1 月至 2015 年 12 月 28 家意大利成人和 6 家儿科血液科住院的血液恶性肿瘤(HM)患者的病历,在此期间诊断出有记录的真菌菌血症。
在研究期间,我们记录了 215 例真菌血流感染(BSI)。微生物分析记录表明,BSI 由 17 例患者(8%)的霉菌和 198 例患者(92%)的酵母菌引起,其中 174 例(81%)患者鉴定为念珠菌属。
霉菌和酵母菌感染的死亡率分别为 70%和 39%。感染是霉菌组 53%和酵母菌组 18%患者死亡的主要原因。多变量分析显示,ECOG≥2 和感染性休克与死亡率增加显著相关,而中心静脉导管(CVC)的移除与生存率的提高相关。当仅考虑念珠菌血症患者时,ECOG≥2 和 CVC 的移除与总死亡率有统计学上的关联。
虽然念珠菌血症代表了一组具有良好预后的 BSI,但它的危险因素与所有真菌菌血症的危险因素基本重叠,尽管与其他真菌 BSI 相比,念珠菌血症相关的死亡率较低。真菌 BSI 的管理仍然是一个复杂的问题,需要关注患者和疾病特征,以采取个性化的治疗方法。
