Filter by:Staphylococcus aureus is a bacteria that causes serious, often life threatening infections including pneumonia, wound, and bloodstream infections. Persons with AIDS are at high risk for S. aureus infections. They are also at high risk for nasal carriage of S. aureus. In fact, nasal carriage is a known risk factor for subsequent S. aureus infection. Topical mupirocin, an antibiotic when applied to the anterior nares, is a safe, effective way to eliminate S. aureus colonization. Some studies have shown that mupirocin can also decrease the risk of S. aureus infection, but many of those studies utilized historical controls and none were rigorously tested among AIDS patients over an extended period of time. The main purpose of this randomized, double-blinded, placebo controlled study is to determine if mupirocin can eliminate S. aureus nasal colonization in residents at PSI (inpatient, drug rehabilitation facility for AIDS patients in the Bronx.) PSI residents currently have a high incidence of S. aureus nasal colonization and infection. Nasal cultures followed by twice daily application of mupirocin vs. placebo for five days will be performed on a monthly basis for 8 months. the study will examine whether mupirocin decreases the incidence of S. aureus infections and prevents S. aureus nasal colonization. The study is important because it may show that mupirocin is an effective way to eliminate nasal colonization and prevent S. aureus infections in AIDS patients, among those at highest risk for serious S. aureus infection. Hypothesis: Monthly application of mupirocin will reduce nasal colonization with S.aureus
The purpose of the study is to determine the effect of an investigational oral rinse in reducing uropathogens and treating uncomplicated urinary tract infections.
The primary objective is to study the value of serum procalcitonin as a predictive marker for severe bacterial infection in febrile infants. 2200 febrile infants aged less than 3 months will prospectively be included. All infants will have a measure of Procalcitonin concentrations. Comparison of the mean value of Procalcitonin concentration in infants with and without serious Bacterial infection. Evaluation of the area under the ROC for Procalcitonin concentration.
Infection with human immunodeficiency virus (HIV) causes decline in immunity or the ability to fight infection and progresses to acquired immunodeficiency disease (AIDS). Anti-HIV drug treatment has improved the prognosis of persons with HIV infection, but is expensive and potentially toxic. Low micronutrient levels occur in the blood even in early stages of HIV infection and increase risk of a poorer prognosis, but the role of micronutrient and antioxidant supplements in medical management of HIV/AIDS is not well defined. The proposed clinical trial aims to assess if supplementation of untreated HIV-infected adults with a micronutrient and antioxidant preparation can delay decline in immunity or disease progression or start of anti-HIV drug treatment compared with supplementation with standard multivitamins. If the findings are positive, the study has implications for health and health care savings.
We put forward that probiotics have an effect on infectious episodes evolution in subjects aged 60 years or over. The main objective of this research is to observe the effect of consumption of the probiotic on the average number of days with infectious episodes.
This is a protocol designed to randomize subjects with acute HIV infection to receive standard HAART or mega-HAART for subject who are enrolled in SEARCH 010 study (protocol title: Establish and characterize an acute HIV infection cohort in a Thai high risk population. To describe the impact of standard HAART versus mega-HAART initiated during the acute HIV infection period on immunological and virological outcomes.
Urinary tract infection (UTI) is a common infection in patients in the intensive care unit (ICU) that increases length of stay but not mortality. It is not known whether antibiotic treatment will alter outcomes. Our previous studies have documented wide practice variations exist amongst doctors, including prescribing antibiotics to asymptomatic patients. Therefore, the merits of various ways to manage the infection require further studies to minimize the potential for over-prescribing of antibiotics, a practice that can increase the development of resistant bacteria. The objective of this pilot study is to determine the feasibility of conducting a larger definitive study that will determine the effect of catheter change and/or systemic antibiotics as compared to no interventions on outcomes and resource utilization in ICU patients with UTI. Patients will be randomized to receive no treatment, antibiotics alone, urine catheter change alone, and both catheter change and antibiotics. Their clinical outcomes will be assessed. Results from the pilot trial will provide information about whether it is feasible to conduct the larger definitive trial. Results of the definitive study will provide guidance to clinicians on how to manage a frequent clinical problem and optimize antibiotic usage.
Probiotics are dietary supplements containing potentially beneficial bacterial strains such as Lactobacillus. The safety of oral administration of probiotics has been demonstrated in hundreds of studies using adults over the last 30 years. Very few studies have been conducted with children. UTI in girls occur when virulent bacteria migrate from the rectum and colonize the vagina and peri-urethral mucosa, thus gaining access to the bladder. This study will randomize girls to ARM A (probiotics + placebo) and ARM B (antibiotics + placebo) to determine if UTIs are decreased when the probiotics are given.
The goal of this 3-year project is to control the spread of community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) in the Dallas County Jail. CA-MRSA is a bacterium spreading rapidly through healthy populations and becoming an epidemic in many regions of the U.S. Many people in the community are asymptomatically colonized by MRSA. There have been outbreaks of MRSA infections at prisons and jails. We will study the spread of MRSA in the jail to better understand how the bacteria are transmitted from person to person there and how we can prevent their transmission. All detainees asked to participate must give informed consent to do so; their privacy will be carefully protected. Detainees with a history of allergy to CHG will be excluded. Seventeen objects in the jail will be sampled for contamination with MRSA. Bacteria will be collected from all cultures obtained from patients with bacterial skin infections for 18 months in a part of the jail in order to determine how frequently these infections are caused by MRSA relative to other bacteria. A group of about 1500 adult detainees will be tested for colonization with MRSA in order to determine how commonly detainees carry the bacterium. A cluster-randomized 6-month study will be undertaken among these detainees and those who take their places when they leave the jail to determine if chlorhexidine (CHG)-containing disposable wash cloths for skin cleaning can decrease the prevalence of MRSA skin or nose colonization. Detainees receiving CHG cloths (about 500 detainees) will be compared to detainees receiving water-soaked cloths for skin cleaning (about 500 detainees) or no intervention (about 500 detainees). The primary outcome will be a difference in average colonization prevalence in detention tanks, which are discrete detention units housing detainees, comparing the usual care to the CHG-exposed tanks after 6 months of CHG cloth use. A secondary outcome will be a decrease in skin infections from any cause in the tanks receiving CHG compared with usual care. All of the MRSA isolates and a sample of the S. aureus isolates susceptible to methicillin from specimens colonizing or infecting detainees, as well as those contaminating surfaces and objects in the jail will be tested genetically in order to determine which strains of MRSA are present in the jail. This study may identify ways to stop the spread of MRSA among people in jails and prisons, as well as other places.
This study is designed to demonstrate that women in labor become infected without exhibiting any clinical signs or symptoms of infection.
