The aim of this study was to prospectively investigate 120 cases of viridans streptococcal bacteraemia (VSB) in 117 patients in major university hospitals in Slovakia in 2000-2002 (3 y) for antibacterial susceptibility, risk factors and outcome. From 127 episodes, 16 (13%) of VSB were caused by PEN-R strains and 13 (10%) by ERY-R strains. 32 cases had cancer as underlying disease (20 haematological), 41 had endocarditis and 35 were elderly (>65 y of age) patients. Concerning mortality, 29 of 127 patients died (24%). There were several risk factors associated with mortality. Solid tumour as underlying disease (p<0.02), stroke (p<0.002), concomitant lung infection (p<0.01), endoscopic procedure (p<0.036), intubation (p<0.0008), ventilatory support (p<0.002), and coma (p<0.009) were associated with more deaths. A comparison of 115 bacteraemias to 13 bacteraemias caused by erythromycin-resistant strains of Streptococcus viridans was performed. There were no significant differences in underlying disease, risk factors and mortality. Erythromycin resistance in bacteraemias caused by S. viridans did not have significant impact on outcome of the patients, nor did it show specific relation to analysed risk factors in our study. 14.5% of VSB were cause by PEN-resistant viridans streptococci. Risk factors for penicillin resistance were ventilatory support (p<0.01), intubation (p<0.001) and resistance to other antibiotics: 8 of 16 (50%) of PEN-R VSB were resistant also to erythromycin or cotrimoxazole or tetracycline compared with 9% of PEN-R VSB (p<0.005). Endoscopic procedures in the upper respiratory system were at risk for development of PEN-R VSB. There was also difference in outcome; 71% vs 22.5% (p<0.0002) of cases infected with PEN-R VSB died compared to PEN-S VSB. PEN-R is therefore clinically significant in VSB.
To assess the antibiotic policies of Central European countries, we performed an overview of antibiotic stewardship, prescription habits and antibiotic prescription regulatory procedures. Since most Central European countries have had centralized health care and drug policies, the situation 10 years after decentralization is surprising. Only 3 of 10 Central European countries have some regulation of prescription of antibiotics, only 4 restrict some antibiotics, only 5 have hospital and only 3 national antibiotic policies. In all but 3 countries physicians can prescribe quinolones and/or 3rd generation oral cephalosporins as first-line antibiotics. Information on local and national antibiotic policies in Central and Eastern European countries is given including prescription guidelines for antibiotic use in community and hospital.
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.
