Clinical and Microbiological Outcomes of Infections Due to Carbapenem-Resistant Gram-Negative Bacteria...
Drug ResistanceMicrobialCarbapenems are a class of antibiotic agents which kill a broad spectrum of bacteria. Infections due to gram-negative bacteria which have acquired resistance to carbapenems are increasing, especially with Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa . The optimal treatment of such infections is not known. Antibiotics like polymyxin, tigecycline and rifampin are used alone or in combination with other antibiotics. The outcome of using these new and old drugs is not well studied. This observational study aims to study the clinical and microbiological outcomes of these infections and treatment at our institution.

Evaluation of Body-worn Multimodal Hand Hygiene System. Impact on Health-Care Associated Infections...
Nosocomial InfectionEvaluate the efficacy of a multimodal hand hygiene system in the intensive care unit environment and evaluate any impact on health care associated infections.

Cerebrospinal Fluid (CSF) Pharmacokinetics of Antimicrobials in Children
InfectionsThe purpose of this study is to learn more about antimicrobials, especially drug levels in the CSF that would normally be used in young children as part of standard care. These drugs are approved by the Food and Drug Administration (FDA) for treating infections. They are used extensively in children in the United States, but they have not been extensively studied in children or babies. The investigators do not have very much information on how children and babies handle these drugs; that is, how long it takes for the drugs to be removed from the blood circulation and to pass out of the body and how much goes into the central nervous system. The investigators also do not have good information to guide how often the investigators should give the drugs to children and babies to get the maximum effect on infections with the minimum amount of drug. Thus, the investigators will collect more information about how these drugs should be used in children and babies by doing this drug levels research study.

Brain Deficits in HIV/HCV Coinfected People Before and After Anti-HCV Therapy
HIVHepatitis C1 moreThis study will evaluate the impact of standard hepatitis C virus treatment on brain deficits in people who are infected with both HIV and the hepatitis C virus.

Bacterial InfectionsEye InfectionsThe purpose of this study is to evaluate the drug concentrations of AzaSite™ compared to Vigamox at various time points in conjunctiva tissue of healthy volunteers

Influenza in People With Normal and Weakened Immune Systems
Viral InfectionsRespiratory InfectionsThis study will evaluate how the immune system responds to influenza infection and compare how the infection differs in patients with a weakened immune system versus those with a healthy immune system. Patients at the NIH Clinical Center who are older than 2 years of age and who are diagnosed with influenza A or B may be eligible for this study. Patients with healthy immune systems and weakened immune systems are included. Participants answer questions about how they are feeling and have a physical examination to evaluate their symptoms. Blood and nasal fluid are collected on the first day and then every other day for a total of 8 days. Nasal fluid is collected by either inserting a small tube in the nose and washing the nose with salt water and collecting the fluid obtained, or by rubbing the inside of the nose with a swab. Physical examinations are repeated on the days that blood and nasal fluid are collected.

Host Response to Urinary Tract Infection in Women
Urinary Tract InfectionThis study is being done to identify those elements of the immune response that may predispose a woman to recurrent urinary tract infection. We suspect that lesser effectiveness of certain components of the host response will lead to recurrent urinary tract infection. We will also evaluate the role that the bladder reservoir may play in recurrent urinary tract infection.

ACE393-103 Vaccination Challenge Study
Campylobacter InfectionThe purpose of this study is to determine whether ACE393 vaccination can protect against Campylobacteriosis in a challenge model.

Iron Absorption and Utilization in Adolescents Infected With Malaria Parasites, Hookworms or Schistosoma...
MalariaFalciparum2 moreThe aim of this study is to investigate the change in iron metabolism in relation to malaria and helminth infections using a stable isotope technique.

Intervention Study to Improve Antibiotic Prescription in Outpatient Care
Respiratory Tract InfectionsUrinary Tract InfectionsAntimicrobial resistance has become a world-wide problem and antibiotic consumption is a major driving force for the development of resistance. Thus optimization of antibiotic prescription and reduction of unnecessary antimicrobial treatment are essential in the prevention and reduction of antimicrobial resistance rates. The goal of this study is the improvement of antibiotic prescription in outpatient care. The study will take place within a Swiss-wide sentinel surveillance network of physicians. The participating physicians will be randomised in a control and intervention group. The intervention group will receive therapeutic guidelines for the treatment of upper and lower respiratory tract infections and lower urinary tract infection as well as regular feed-backs on the prescription pattern of the sentinel physicians during the past months. Sentinel physicians will collect information about each antibiotic prescription, its indication and characteristics of the patient. Our hypothesis is that the prescription pattern in the intervention group will be optimised and unnecessary antibiotic therapy will be reduced compared to the control group.
