Abstract:

Objective To analyze the etiological characteristics and prognostic risk factors of patients with fungal bloodstream infections,and to provide a reference for clinical prognosis assessment. Methods A total of 112 patients with fungal bloodstream infections from Lishui Central Hospital from January 2019 to December 2023 were enrolled. According to the survival status for 28 d after the occurrence of fungal bloodstream infection,they were classified into survival group and death group. The clinical data,types of fungi and results of in vitro drug susceptibility tests were collected. The differences in various indicators between survival group and death group were compared. Multivariate Logistic regression analysis was used to evaluate the risk factors affecting the prognosis of patients with fungal bloodstream infections. Receiver operating characteristic(ROC)curve was used to evaluate the efficacy of each risk factor in predicting patient mortality. Results A total of 182 fungi were isolated. The top 3 fungal species were Candida albicans(82 isolates,45.1%),Candida tropicalis(33 isolates,18.1%)and Candida glabrata(23 isolates,12.6%). Among the 112 patients with fungal bloodstream infections,50 patients died,with a mortality rate of 44.6%. The patients were mainly distributed in the intensive care unit(46 cases,41.1%),hematology department(13 cases,11.6%),oncology department(9 cases,8.0%)and neurosurgery department(8 cases,7.1%). Cardiovascular system diseases,no surgical operation and elevated DD,decreased PLT count were risk factors for death in patients with fungal bloodstream infection [odds ratios (OR) were 3.59,0.11,0.98 and 1.09,95% confidence intervals (CI) were 1.01-12.70,0.02-0.56,0.97-0.99 and 0.99-1.18,respectively,P<0.05]. The areas under curves(AUC)for PLT count and DD in predicting mortality were 0.755 and 0.739,respectively. Conclusions The pathogenic fungi of fungal bloodstream infections in Lishui Central Hospital are mainly Candida albicans. PLT count and DD have predictive value for the prognosis of patients.
