Filter by: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.
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 will determine the amount of liver scarring (fibrosis) or liver damage in people infected with 1) hepatitis B virus (HBV, a virus that can infect the liver); 2) HIV (the virus that causes AIDS); 3) both HBV and HIV; and 4) neither HBV nor HIV. Liver fibrosis and liver damage can have many causes, including alcohol, certain medicines, exposure to some contaminated foods and infections with viruses that affect the liver (such as HBV). About 25 million people in sub-Saharan Africa are infected with HIV and about 50 million with chronic HBV, yet very little information is available on how many people are infected with both viruses and the medical implications of co-infection. Participants in Uganda s Rakai Health Sciences Program (RHSP) or Infectious Diseases Institute (IDI) clinic who are 18 years of age or older may be eligible for this study. People enrolled in the study come to the clinic for at least one visit and may be asked to return yearly. During the visit, participants undergo the following procedures: - Questionnaire and a short interview about their health and quality of life. - Physical examination and blood draw. The blood is tested for HBV and other factors that may suggest liver disease. Blood drawn at previous clinic visits or from other studies may also be tested. - Liver evaluation using a FibroScan, a medical device that uses elastic waves to measure liver stiffness in a process similar to ultrasound scanning. For this test, the subjects lies flat on the back with the arm extended out. The tip of the machine s probe is covered with gel and placed on the skin between the ribs at the level of the right lobe of the liver. The machine produces a little tap on the skin that sends a wave out and checks how fast the wave moves. The speed of the wave indicates the amount of scarring in the liver.
This pilot study in our medical intensive care unit will evaluate the clinical and cost-effectiveness of an active surveillance program for methicillin-resistant Staphylococcus aureus (MRSA), compared to routine daily bathing with chlorhexidine gluconate (CHG)-impregnated cloths. Outcomes include rate of MRSA acquisition, and of other hospital-acquired infections (e.g., catheter-associated bloodstream infections).
To further characterize the immune responses induced after an influenza vaccination performed either via the ID or the IM routes in two clearly distinct populations. Objectives: - To describe the immune response per age group and vaccine group after vaccination. - To describe the safety of the vaccines per age group and per vaccine group after vaccination.
This is a multi-center study designed to evaluate the safety and immunogenicity of a Fluzone revaccination in elderly adults aged ≥ 65 years. Primary Objective: To describe the safety profile for all subjects. Secondary Objective: To describe immunogenicity 28 days following revaccination with one of three Fluzone formulations.
A phase Ib partially blinded pilot study to evaluate the safety and immunological effects of PENNVAX-B with or without co-administration of constructs containing DNA encoding for the expression of either IL-12 or IL-15. Primary objectives 1. To determine the safety of HIV-1 DNA constructs (PENNVAX-B). 2. To determine the safety and optimal doses of the IL-12 and the IL-15 adjuvant constructs when given with PENNVAX-B. Secondary objectives 1. To compare the various vaccine groups for their immunological responses to several HIV-1 antigens, utilizing the ELISPOT assay. 2. To analyze antibody responses to the vaccine antigens over time. 3. To measure CD8 cell proliferative responses to vaccine antigens over time.
