Filter by:This is a Phase 3, multicenter, prospective, randomized, double-blind, double dummy study of CXA-201 Intravenous (IV) infusions (1500mg q8h) and metronidazole (500mg q8h) versus meropenem (1000mg q8h)for the treatment of adults with Complicated Intraabdominal Infections (cIAI).
This study is designed to evaluate the safety, tolerability, and immunogenicity of an investigational pneumococcal vaccine in healthy adult volunteers. Primary Objective: - To evaluate the safety and tolerability of an investigational pneumococcal vaccine. Observational Objective: - To evaluate the immunogenicity of an investigational Pneumococcal vaccine.
This study is designed to evaluate the safety, tolerability, and immunogenicity of two investigational pneumococcal vaccines at three dose levels in healthy adults. Primary Objective: - To evaluate the safety and tolerability of two investigational pneumococcal vaccines. Observational Objective: - To evaluate the immunogenicity of the investigational pneumococcal vaccines.
The investigators intend to investigate whether the rise in childhood obesity is caused by the loss of recurrent and chronic infections in modern, industrialized society, beginning in utero and extending through early childhood. The investigators will also examine whether the antimicrobial triclosan, present in numerous cleaning and hygiene products, decreases the incidence of infection within a household.
The purpose of this study is to learn more about the safety and dosing of rifampin in infants.
Background: - Parainfluenza is a virus that can cause infections in people. Most people infected with this virus have mild symptoms including fever, cough, red eyes, or runny nose (a common cold). Some people, especially those with a weakened immune system, get very sick from this virus. They may have difficulty breathing or develop lung infections. Currently, there are no specific treatments for parainfluenza. However, a drug called DAS181 may make the virus go away faster. Researchers are interested in testing DAS181 to see if it is safe and effective against parainfluenza. Objectives: - To test the safety and effectiveness of DAS181 as a treatment for parainfluenza. Eligibility: - Individuals at least 18 years of age who have the parainfluenza virus and have developed symptoms within the past 10 days. Design: - Participants will be screened with a physical exam, medical history, and questions about symptoms and activity levels. Participants will also have a lung function test and provide blood and nasal fluid samples. - DAS181 is an inhaled medication, and everyone will receive a study medication inhaler. Participants will receive either DAS181 or a placebo through the inhaler. They will take it once every day for 5 days. - Participants will have monitoring visits on days 2, 4, 7, 10, 14, and 28 to provide blood and nasal fluid samples and have a lung function test. - Participants who still have the virus in their system on Day 28 will return to the clinic on Day 42 for more tests. Participants who still have the virus in their system on Day 42 will return to the clinic on Day 56 for more tests. - Participants will have followup visits 6 months and 1 year after the start of the study.
HIV progression is closely associated with chronic immune activation driven by leakage of bacterial products from a damaged gut, the investigators largest immunological organ. Notably, the degree of immune activation has been suggested to be a better predictor of disease progression than plasma viral load, and markers of immune activation and gut damage have been identified as therapeutic targets per se. The major damage by HIV to the immune system is an initial massacre of gut mucosal CD4+ Th17 cells. Interestingly, a normal gut flora has been shown to induce the maturation of Th17 cells in the small intestine mucosa. Preliminary reports have shown that the gut flora is altered in HIV-1 infection compared to controls. In this project, the investigators will characterize microbial composition of gut flora in chronic HIV infection with ultradeep sequencing. Gut flora composition will be related to clinical data as well as quantitative data of circulating microbial products and activation markers. Second, in a randomized clinical trial (RCT) the effect of probiotic lactobacilli on HIV pathogenesis and progression will be tested. This Gram-positive strain is clinically tested and is able to colonize the gut.
The study hypothesis is that F-18-FDG PET/CT and microcalorimetry might have a diagnostic value in the detection of permanent central venous catheters (PCVC) infection when conventional means of PCVC infection detection are non-conclusive.
This study aim to test the hypothesis that human S.suis infections are associated in time and space with outbreaks of Porcine Reproductive and Respiratory Syndrome (PRRS) virus or other diseases in pigs.
The investigators propose to study the impact of nucleic acid amplification testing (NAT) screening for acute Human Immunodeficiency Virus (HIV) and Hepatitis C (HCV) infections and Less-Sensitive Enzyme linked Immunoassay (LS-EIA) or 'detuned' testing Vironostika, Trinity Biotech BED, or Ortho-Clinical Diagnostic Vistros ECi for early HIV infection in conjunction with routine rapid HIV testing at HIV counseling and testing sites and venues in the San Diego county. The overarching goal of this study is to develop and implement a system to identify, notify and engage into care those individuals with recent HIV infection in order to better define the HIV and Hepatitis C Virus (HCV) epidemics in the San Diego county and to evaluate and characterize HIV transmission dynamics within the San Diego population.
