Filter by:Nosocomial bloodstream infections are important causes of morbidity and mortality caused by AmpC beta-lactamase-producing Enterobacteriaceae. The information collected will optimize the management of patients with nosocomial bloodstream infections.
The impact of continuous veno-venous haemofiltration (CVVH) on sepsis-induced multiple organ failure severity is controversial. We thus sought to assess the effect of early application of haemofiltration on the degree of organ dysfunction and plasma cytokine levels in patients with severe sepsis or septic shock.
This study investigates whether the prophylactic use of moxifloxacin during high-dose chemotherapy followed by autologous stem cell transplantation reduces the incidence of clinically significant bacteremia. Further investigations include time to occurrence of fever, duration of fever, overall survival and antibiotic sensitivity of blood isolates.
The purpose of this study is to investigate why some people develop life-threatening infections caused by the bacteria Staphylococcus aureus, while other people do not. It is possible that the infectious ability of the bacteria can determine whether an infection develops and its severity. The investigators will look at old blood and nasal specimens collected from 1000 adults who had S. aureus infections and who were hospitalized at Duke University Medical Center. Previously collected health information regarding these patients and the specific bacterial traits in the samples will be studied. Eventually this information may be used to help treat and prevent S. aureus infection.
The purpose of this study is to review medical records at MEDVAMC in order to relate the outcome of bacteremic MRSA infection to the antibiotics selected for treatment.
More than 80 patients at the University of Pittsburgh Medical Center have been infected with Pseudomonas aeruginosa, lacking susceptibility to all commercially available antibiotics except "colistin". This antibiotic was developed in the 1960s and preliminary pharmacokinetic studies were performed at that time. Dosing recommendations, on the basis of these pharmacokinetic studies, are listed in the drug's product information. However, there are no dosing recommendations for patients requiring renal replacement therapy (either intermittent hemodialysis or continuous venovenous hemofiltration). Furthermore, the science of antibiotic dosing ("pharmacodynamics") has changed significantly since the 1960s and it is quite possible that the dosing recommendations listed in the product information are not optimal. Furthermore, even though physicians refer to "colistin" administration, the only intravenous form of the drug is colistin methanesulfonate (CMS). CMS is converted in the body to colistin. Both CMS and colistin have different pharmacokinetic and antimicrobial activities. For this reason, we, the investigators at the University of Pittsburgh, are performing a pilot study of the pharmacokinetics of intravenous CMS/colistin in patients requiring this antibiotic for clinical purposes. Plasma concentrations will be determined around a CMS/colistin dose once the drug has reached steady state. Concentrations in pulmonary epithelial lining fluid will also be determined in patients with pneumonia. Microbiologic and clinical endpoints will be determined and will be correlated with these concentrations. The measurement of CMS and colistin levels will be determined by a laboratory in Australia which developed these assays. A submission is being made to the National Institutes of Health (NIH) for funding of a multicenter study which will address this research question with a greater sample size. The study proposed here is a pilot study in order to prove the feasibility of the research approach and to provide preliminary data for the NIH proposal.
Hospitalized patients at least 18 years of age, with Staphylococcus aureus bacteremia (SAB) will be enrolled into the study and receive one dose of Aurexis® intravenously on Study Day 1, and will be followed until Study Day 57. Aurexis is a humanized monoclonal antibody that is designed to combat Staphylococcus aureus. The purpose of this study is to assess the safety and pharmacokinetics of standard antibiotic therapy, plus Aurexis or Placebo for treatment of (SAB). Additionally, certain tests and measurements will be conducted to preliminarily determine if Aurexis demonstrates any benefit to these patients.
The aims of this study are to: - Determine the risk factors for multidrug resistance in bloodstream isolates of Gram negative bacilli - Determine the mechanisms of multidrug resistance in bloodstream isolates of Gram negative bacilli - Determine the risk factors for failure of prompt clearance of the blood of Gram negative bacteria - Determine the survival of patients with Gram negative bacteremia - Determine if failure of prompt clearance of the blood of Gram negative bacteria is a predictor of mortality following this infection
Pharmacokinetics is the study of the disposition of drugs in the body, while pharmacodynamics considers the interaction of the drug at the site of infection over time. Mathematical models of antibiotic pharmacodynamics are sometimes used to predict if antibiotic doses are sufficient to treat infection with organisms of different minimal inhibitory concentrations of the antibiotic. Based on these models, there has been speculation that the antibiotic cefepime dosed at one gram every 12 hours, is insufficient to kill all organisms within the "susceptible" range. This study of patients treated with cefepime will involve the collection of blood to determine cefepime concentrations, and determine if those concentrations are effective in killing the bacteria at the site of infection.
This is a randomized 2-arm study to compare two different times of giving the drug vancomycin. Half of the patients will begin vancomycin two days before a bone marrow transplant. The other half will get it as soon as they have the first fever. Streptococci are bacteria that live in one's mouth and gut. These bacteria can escape into the blood when the lining of the mouth and gut weakens from cancer therapy. This can make the person who is undergoing a bone marrow transplant very sick. All patients who get this infection are treated with antibiotics. Vancomycin is one drug that is used to treat this bloodstream infection once it is diagnosed. Studies have shown that giving vancomycin before a bone marrow transplant seems to prevent this infection. However, giving vancomycin too soon may increase the chance that the kidneys will be irritated. It may also increase the chance that other bacteria will become resistant to this drug. We, the investigators at Memorial Sloan-Kettering Cancer Center, do not know if waiting to start vancomycin until the patient has a first fever can also prevent this infection.
