The aim of this multicenter survey was to assess risk factors and mortality in patients with persistent fungemia (PF). Cases of persistent fungemia, defined as positive blood culture for at least 3 causative days of antifungal therapy were selected. Forty cases of persistent fungemia (lasting more than 3 days) were compared with 270 non-persistent fungemias appearing within the same period, and analyzed by univariate and multivariate analysis for risk factors and outcome. The median number of days of positive culture was 4.4 (3 - 20): 22 episodes were due to Candida albicans, 1 due to non-albicans Candida spp., 6 episodes due to non-Candida spp. Yeasts: 15 were catheter related, 16 patients had yeast-infected surgical wounds, 12 were neutropenic, 4 cases were caused by species resistant in vitro, 2 to amphotericin B (Trichosporon spp.) and 2 to fluconazole (C. laurentii, C. glabrata). Fifteen patients (37.5%) died, 7 of whom due to fungemia. Nineteen cases had one known risk factor (10 had infected wound, 4 infected vascular catheter, 3 were neutropenic and 2 had inappropriate therapy). Fourteen cases had two known risk factors (4 had wound and infected catheter, 4 neutropenia and infected catheter, 2 neutropenia and resistant organism, 4 other combinations. Two cases had 3 known risk factors and one had 4 risk factors for persistent fungemia. Artificial ventilation, C. glabrata etiology, non-Candida spp. yeasts such as Trichosporon spp. and Cryptococcus spp. and prior surgery were significantly associated with persistent fungemia in univariate, whereas only C. glabrata etiology in multivariate analysis. Breakthrough fungemia during empiric therapy with fluconazole was also observed more frequently in patients with persistent fungemia. However, there was no difference in both attributable and overall mortality between both groups.
Key Clinical MessagePlain films aid management and do not delay the emergency treatment of a stable patient with penetrating neck trauma in the resuscitation room and thus should be taken while arranging CT angiography.
This study prospectively investigated all 157 cases of Acinetobacter baumannii bacteremia occurring in major university hospitals or tertiary care institutions in Slovakia during 1999 in order to determine the antimicrobial susceptibility, risk factors and outcome. Resistance to meropenem was 7.4, gentamicin 35.6, amikacin 26.5, cefepime 20.4 and ciprofloxacin 32.7%, but was only 17.3% to cefoperazone/sulbactam or ampicillin/sulbactam. Antimicrobial susceptibility of A. baumanii was lowest among isolates from cancer patients (ceftazidime 58%, piperacillin/tazobactam 52% and azthreonam 48%; p < or = 0.01-0.001). In univariate analysis, several risk factors, such as wound infection (p < or = 0.01) and ventilatory support (p < or = 0.0001), were significantly related to A. baumannii bacteremia in surgical patients. Neutropenia (p < or = 0.0001), antineoplastic chemotherapy (p < or = 0.0001) and prior antibiotic therapy (p < or = 0.0006) were significant risk factors for A. baumannii bacteremia in cancer patients. In addition, ventilatory support and surgery (p < or = 0.0001) and prior antibiotic therapy (p < or = 0.01) were significantly related to A. baumannii bacteremia in children. Colonization at other body sites (p < or = 0.05), diabetes mellitus (p < or = 0.04) and decubital ulcers/burns (p < or = 0.002) as underlying disease were significantly related to death due to A. baumannii bacteremia. In a multiple logistic regression model, decubital ulcers/burns as underlying disease (p < or = 0.0006; relative risk 5.08) and nosocomial pneumonia (p < or = 0.045; relative risk 5.08) were independent predictors of mortality. Mortality was similar between cancer and surgical patients but significantly lower in children vs. adults (p < or = 0.009).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
