Objective: To identify the microorganisms isolated on the pericatheter skin, catheter tip and blood stream of patients on hemodialysis by central venous catheter, to verify the profile of sensitivity of these microorganisms to antimicrobials and to assess the clinical evolution and mortality related to these microorganisms. Methods: A cross sectional study. The strains were isolated from the patients on hemodialysis by central venous catheter that, in a previous study, presented pericatheter skin, catheter tip and blood stream infection and were analyzed for microbiological profile and lethality related. Results: 128 microorganisms were isolated in the bloodstream in the 94 patients studied. There were 35 cases of septicemia and 27 of endocarditis. The mortality in cases of endocarditis due to methicillin-resistant Staphylococcus aureus was 100%. Conclusion: Infection in the bloodstream and endocarditis caused by methicillin-resistant Staphylococcus aureus was predictive of mortality and lethality. ResumoObjetivo: Identificar os microrganismos isolados da pele pericateter, ponta do cateter e corrente sanguínea de pacientes em hemodiálise por cateter venoso central, verificar o perfil de sensibilidade destes microrganismos aos antimicrobianos e avaliar a evolução clínica e a mortalidade relacionada a estes microrganismos. Métodos: Estudo transversal. As cepas isoladas de pacientes em hemodiálise por cateter venoso central que em estudo prévio apresentaram infecção na pele pericateter, ponta do cateter e corrente sanguínea foram analisadas quanto ao perfil microbiológico e letalidade relacionada. Resultados: Foram isolados 128 microrganismos em corrente sanguínea nos 94 pacientes estudados. Ocorreram 35 casos de septicemia e 27 de endocardite. A letalidade nos casos de endocardite por Staphylococcus aureus resistente à meticilina foi 100%. Conclusão: Infecção em corrente sanguínea e endocardite por Staphylococcus aureus resistente à meticilina são preditivas de alta mortalidade e letalidade.
Objectives: to assess the prevalence of colonization and infection by multidrug-resistant bacteria in patients undergoing kidney transplantation and identify the rate of infection, morbidity and mortality and associated risk factors. Methods: a prospective cohort of 200 randomly included kidney transplant recipients. Epidemiological surveillance of the studied microorganisms was carried out in the first 24 hours and 7 days after transplantation. Results: ninety (45%) patients were considered colonized. Female sex, hypertension and diabetes (p<0.005), dialysis time (p<0.004), length of stay after transplantation, delayed renal function, and length of stay were identified as risk factors. The microorganisms were isolated from surgical site, bloodstream and urinary tract infections. Conclusions: colonization by resistant microorganisms in kidney transplant patients was frequent and risk factors associated with infection were identified. The results should guide the care team in order to minimize morbidity and mortality related to infectious causes in this population.
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.
