Filter by:Hospital-acquired infections are common and frequently lead to poor outcomes, including death, in affected patients. Two common organisms that cause infections in the hospital are methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus (VRE). One strategy used to prevent these infections is contact isolation of hospitalized patients with MRSA and/or VRE. It is unclear whether contact isolation decreases the rate of infection with MRSA and/or VRE. The CONTACT-PILOT study is designed to test the hypothesis that contact isolation decreases the rate of infection with MRSA and/or VRE in patients in the intensive care unit (ICU). The study will enroll all adults in the Medical ICU and will run between September 2017 and April 2018. During some months, all patients in the Medical ICU patients will be placed in isolation for MRSA or VRE if they have a current infection or colonization with either organism, or a recent history thereof. During other months, patients will only be placed in isolation for MRSA or VRE if they have an active, highly-transmissible infection with either organism, such as a pneumonia or an open, draining wound.
This is a multi-center, randomized phase III study to evaluate the clinical effectiveness of AeroVanc in persistent methicillin-resistant Staphylococcus aureus (MRSA) infection in patients with cystic fibrosis (CF).
Infections due to S. aureus are a major healthcare burden. Currently there is not an effective way to prevent S. aureus infection. Treatment failure can happen in up to 20% of patients with SSTI and mean additional cost per patient can be over $1500. Antibiotics are often prescribed for the treatment of CA-S. aureus SSTI. Current IDSA CA-MRSA guidelines suggest that incision and drainage alone may be adequate for management of uncomplicated CA-S. aureus skin abscesses and there is uncertainty about the need of antibiotics. It is not known whether antibiotics are helpful in decreasing S. aureus colonization rates or preventing future S. aureus infections. Though resolution of acute abscess after drainage may be unchanged by antibiotic administration, the impact of managing S. aureus abscess without antibiotics on ongoing S. aureus colonization and recurrent infection requires further study. This study seeks to examine whether the management of initial S. aureus abscesses with incision and drainage in addition to antibiotic therapy is an effective means of preventing recurrent infection. The prolonged longitudinal follow-up of this study is another unique characteristic that will enable the investigators to capture data about recurrences of infections.
Methicillin-susceptible (MSSA) and Methicillin-resistant (MRSA) Staphylococcus aureus (SA) are two of the most important infectious pathogens in CF, with 69% of CF patients having lung infection with MSSA or MRSA in the last year. Wolter and co-workers recently demonstrated that a specific morphologic subtype of MSSA and MRSA, small-colony variant Staph aureus (SCV-SA), is associated with greater decline in lung function and worse clinical outcomes. SCV-SA is already recognized for its ability to contribute to persistent infection, likely due to SCV-SA's ability for intracellular growth, as well as its increased antibiotic resistance compared to normal-colony SA. To investigate the epidemiology and clinical significance of SCV-SA in CF, and explore the hypothesis that SCV-SA may require unique antibiotic treatment strategies to optimize clinical response, the investigators will perform the following: 1. Characterize the epidemiology of SCV-SA infection in both an adult and pediatric CF population and investigate the clinical significance of SCV-SA infection in CF by comparing clinical characteristics and outcomes of CF patients with SCV-SA compared to those with to normal-colony MSSA/MRSA. 2. Characterize the unique microbiologic characteristics of SCV-SA infection in CF by evaluating antibiotic susceptibility profiles and molecular characteristics of SCV-SA in a two large CF patient populations. 3. Perform a 16-patient pilot study of a novel treatment for SCV-SA infection in CF, utilizing low dose rifampin in combination with standard anti-SA antibiotics. These investigations will delineate the role of SCV-SA as a pathogen in CF and provide guidance to optimize treatment strategies of MSSA/MRSA CF lung infection.
1. Drug resistance of G+ cocci is a severe healthcare problem. According to the Ministry of Health National Antimicrobial Resistant Investigation Net (mohnarin) surveillance report, the isolation rate of MRSA is some 60% in China. MRSA infection has become a serious clinical problem; 2. Vancomycin is a bactericidal glycopeptide antibiotic which inhibits bacterial growth by hindering the synthesis of cell wall in bacteria. It exerts strong antibiotic effect to Gram+ bacteria. It is indicated for serious staphylococcus infections especially MRSA infection and has become the gold standard agent in MRSA treatment; 3. Vancomycin is a time-dependent antibiotic, its clinical and microbiological efficacy is related to area under curve（ AUC）/minimum inhibitory concentration （MIC ）(AUIC). Cmin at steady state is an surrogate parameter of AUIC, which is closely associated to the efficacy; 4. AUIC >400 and Cmin between 15~20 mg/L are recommended for effective vancomycin treatment by Infectious Diseases Society of America （IDSA） although it is still disputable; 5. Due to the absence of PK/PD study on vancomycin in China, administration of vancomycin is performed in reference to the recommendation of IDSA. Its suitability to Chinese patients is still to be clarified; 6. Plasma concentrations of vancomycin vary significantly between population and individuals. Factors such as large-volume fluid infusion, hypoproteinemia and renal clearance, etc. will influence the distribution and excretion of vancomycin, resulting in different plasma concentrations between individuals. Results of PK studies differ greatly between China and abroad. Administration based on the AUIC or Cmin recommended by IDSA would not be suitable to Chinese patients. Given the definite long-term benefit of vancomycin treatment, the AUIC or Cmin suitable to Chinese patients must be identified by clinical study. 7. The PK/PD study on vancomycin in the treatment to MRSA septicemia and endocarditis is of great significance for more reasonable use and improved therapeutic efficacy of MRSA infection.
In this study, the investigators intend to compare therapies (abscess surgery and hygiene education compared to abscess surgery and hygiene education followed by decolonization) for Methicillin-Resistant Staphylococcus Aureus skin and soft tissue infections (MRSA SSTI) to determine which is the more effective treatment. The investigators focus on patient centered outcomes as described by the families of MRSA infected patients. Such outcomes are likely to include quality of life, side effects, and school and work attendance. The hypothesis is that treatment with decolonization will decrease the rate of SSTI recurrence and improve overall patient centered outcomes. The rationale is that negative outcomes such as recurrence may be avoided through the use of readily available prevention strategies, but that it is important to determine how burdensome those prevention strategies are for patients and families.
This research is being done to learn more about an approach to remove Methicillin resistant Staphylococcus aureus (MRSA) in patients who are carriers of the bacteria in outpatient settings and among their household members and sexual partners. MRSA is a type of bacteria or germ that can cause bad infections of the skin that can make people very sick. The bacteria have been seen in a high number of persons in the Baltimore area and in hospitals throughout the country. MRSA can be spread from person to person, particularly in homes and among family members and sexual partners. There are three things the investigators hope to learn from this research study: First, the investigators want to find a way to prevent MRSA infections in outpatient settings. By asking questions, the investigators want to look at the things that may increase the risk of having this type of bacteria in you and your family members. Second, the investigators have soaps and oral rinses (Chlorhexidine) and medications (antibiotics; Mupirocin ointment) that have been shown to be effective at removing MRSA. The investigators want to determine if these antibiotics and soaps are best used for everyone in the household or only the individual with known MRSA. Third, as the investigators, we want to learn more about the bacteria by looking at it on the inside. The investigators will do laboratory tests on samples we collect, to learn how MRSA bacteria grow, reproduce and how it develops to behave differently than other types of MRSA bacteria.
This study will test if doctors, nurses and other people who take care of patients in hospitals wearing gloves and gown for all contact with patients in an intensive care unit (ICU) will: - Decrease the chance of patients getting an infection while in the hospital - Decrease the chance of patients picking up bacteria as a result of being in the hospital - Decrease the time a patient spends in the ICU or in the hospital - Increase the frequency of adverse events The study will also look at whether making doctors, nurses and other people who take care of patients wear gloves and gown for all contact with patients will decrease the amount of time healthcare workers spend with patients. This study will gather information by comparing what happens in ICUs that continue to do what they were doing before the study with what happens in ICUs that require healthcare workers to wear gloves and gown for all contact with patients. This study will provide information that will help to make being in the hospital safer for all patients.
This study will find how weight affects the dosing of a drug called sulfamethoxazole and trimethoprim. Currently, the amount of sulfamethoxazole and trimethoprim a patient receives is the same regardless of the patient's weight. The entire cohort was analyzed for the study outcomes. BMI groups were for recruitment purposes only and were not used for ordinal data analysis. All sulfamethoxazole and trimethoprim (Trade name is Bactrim or Septra) medication that you will receive in this study will be referred to as study medication within this informed consent form. This drug is a combination of two antibiotics, sulfamethoxazole and trimethoprim, which belongs to a class of medication known as "sulfones" and is approved by the US Food and Drug Administration (FDA) for the treatment of a wide variety of bacterial infections such as ear infections, urinary tract infections, bronchitis, traveler's diarrhea, and Pneumocystis carinii pneumonia. Sulfamethoxazole and trimethoprim is given orally.
Staphylococcus aureus (S.aureus) is a bacterium that causes many painful skin and soft tissue conditions, such as scalded-skin syndrome, boils, or impetigo. Serious cases may result in deadly complications but S.aureus can usually be treated successfully with antibiotics. There are, however, certain strains which cannot be treated with standard antibiotics. Methicillin-resistant staphylococcus aureus (MRSA) is one such strain. MRSA is increasingly being seen in both hospital and community settings, making it a serious public health issue. People with Atopic Dermatitis (AD), particularly those with a history of Eczema Herpeticum (EH), may be at greater risk for infection by MRSA. The reason for this higher risk is unknown but may be linked to extended treatment with staphylococcus antibiotics in addition to the absence of certain proteins on their skin, which have immune function. The purpose of this study is to determine the reasons for MRSA infection in AD participants with and without a history of EH.
