Active clinical trials for "Infections"

GSK1265744 (744) is an integrase strand transfer inhibitor (INSTI) currently in development for both the treatment and prevention of human immunodeficiency virus (HIV) infection. Renal elimination of unchanged 744 is extremely low, with no parent 744 detected in the urine after a single 30 mg radiolabeled dose. Despite the minimal contribution of renal clearance on overall 744 elimination, renal impairment may potentially inhibit some pathways of hepatic and gut drug metabolism and transport, and as a result may impact 744 pharmacokinetics. The current Food and Drug Administration (FDA) draft guidance for renal impairment studies suggests that a pharmacokinetic (PK) study in patients with renal impairment be conducted even for those drugs primarily metabolized or secreted in bile. The study will be comprised of two cohorts (severe renal impairment and normal renal function) of 8 subjects each. Upon enrolment, each subject will be admitted to the study center and undergo serial PK sampling following a single dose of oral 744 30 milligrams (mg). Subjects will return to the clinic for follow-up evaluations 10-14 days after the 744 30 mg dose.

Healthcare-associated infections (HAI) are a significant public health burden. Even with existence of recommendations on technical strategies to prevent these infections, there is a need for strategies to increase staff engagement within the local organizational and cultural context. Positive deviance is one such approach that engages people in improvement efforts. Positive Deviance is based on the observation that in every community there are certain individuals or groups whose uncommon behaviors and strategies enable them to find better solutions to problems than their peers, while having access to the same resources and facing similar or worse challenges. In the proposed study, the investigators plan to test the effectiveness of using positive deviance based horizontal infection prevention approach to achieve overall reduction of HAIs among hospital inpatients. The investigators hypothesized that a broad and horizontal approach to reduce opportunities for acquisition of nosocomial pathogens using PD will lead to greater reduction of HAI among hospital inpatients compared to standard-of-care infection control approach. The investigators objective was to test the investigators hypothesis and evaluate whether there is greater decline in rate of HAI in the experimental group of wards compared to the control group of wards.

Acinetobacter species have emerged as agents of serious nosocomial infections in critically ill patients. Only a few effective antibiotics are currently available for the treatment of this pathogen and, therefore, sulbactam is being considered as an alternative treatment option. The aims of this study were to i) reveal the population pharmacokinetics and ii) assess the probability of target attainment (PTA) of sulbactam in septic critically ill patients caused by Acinetobacter spp. infections. The study was conducted in septic critically ill patients caused by Acinetobacter spp. Each patient received 2 g every 12 h of sulbactam for 10 days, after which PK studies were carried out on day 4 of sulbactam therapy and a Monte Carlo simulation was performed to determine the probability of attaining a specific pharmacodynamic target.

In patients with asthma, reactions to allergens in the environment (such as mold, pollen, weed, domestic pets, and dust allergens) play an important role in causing asthma symptoms. However, upper respiratory tract infections, typically those caused by the common cold virus, rhinovirus, can also cause asthma to get worse. In previous studies at the University of Virginia, it was found that mild asthmatics, who had high levels of the allergy antibody (called IgE) in their blood, developed more persistent cold and chest symptoms when they were given an infection with rhinovirus (the most frequent cause of the common cold). The cold symptoms produced by rhinovirus tend to peak during the first 4 -7 days of the cold. These symptoms, including nasal congestion, are similar to what you have experienced with previous colds. This study is being done to learn how a common cold caused by a viral infection affects people with asthma. The goal is to learn how to improve the care of asthma symptoms caused by the common cold virus (called rhinovirus). Most adults experience one or two colds caused by rhinovirus every year. In addition, 75-80% of asthma exacerbations caused by viral infections are caused by this virus, primarily in children. Adults are less likely to experience significant changes in their asthma symptoms when they get colds, because they have developed protective immune responses from previous colds which help diminish symptoms.

This research project will study whether the drug telmisartan administered in conjunction with antiretroviral therapy (ART) will help reduce nervous system infection with HIV. The investigators are studying the effect of this treatment in people who have contracted HIV infection within the past three weeks, and thus have a form of HIV called acute HIV infection. The investigators will measure biological markers of immune activation in the blood and cerebrospinal fluid to see if telmisartan may reduce the spread of HIV reservoirs in affected patients.

The objective of the study is to determine Bactiguard coated BIP Endotracheal tube´s tolerability, safety and performance and compare it to a standard un-coated Endotracheal tube.

This randomized phase III trial studies how well caspofungin acetate works compared to fluconazole or voriconazole in preventing fungal infections in patients following donor stem cell transplant. Caspofungin acetate, fluconazole, and voriconazole may be effective in preventing fungal infections in patients following donor stem cell transplant. It is not yet known whether caspofungin acetate is more effective than fluconazole or voriconazole in preventing fungal infections in patients following donor stem cell transplant.

This study will explore the possible effect of a tailored educational intervention towards general practitioners, in order to improve antibiotic prescriptions for respiratory infections.

This study will examine the phototoxicity, a reaction to light that is like exaggerated sunburn, which occurs in people who take medications such as voriconazole, a medication used to fight fungus. Sunscreens might protect the skin from the reaction. Although phototoxicity from voriconazole is not completely understood, it may be related to how that medication is metabolized in the liver by enzymes called cytochrome P450 enzymes-and mainly by one known as 2C19. A way to evaluate phototoxicity is through microarrays, which measure how much each gene is expressed in cells from tissues such as skin. Patients ages 8 and older who are scheduled to begin taking or who currently take voriconazole may be eligible for this study. Also, patients ages 18 to 45 in good health who have skin tone known as Type 2, which usually burns and tans only slightly following sun exposure, may be eligible. All patients will visit the Dermatology Clinic. They will complete two questionnaires, on medical history and medications, as well as the skin response to sunlight, and donate about 3 teaspoons of blood. Patients who are scheduled to take voriconazole will visit the clinic four times, that is, two visits 2 consecutive days before beginning the medication and two visits on 2 consecutive days after taking it for at least 7 days. Each visit will take 1 to 2 hours. Patients about to take voriconazole will have a blood test and undergo a physical exam of the skin test site, on the buttocks. Researchers will take photographs of the specific site and do tests to measure skin reaction to ultraviolet (UV) light. UV light will be shined on 15 small areas of the skin, each 1 x 1 centimeters. After 24 hours, any redness that occurs on the skin will be checked. Afterward, patients will begin taking voriconazole according to directions by the researchers. At 10 or more days later, patients will visit the clinic. Sunscreen will be applied and 1 hour later after administration of voriconazole, a blood sample will be drawn to check the level of medication. Then UV light will be shined on 23 areas of skin 1 x 1 centimeters. More photographs will be taken of test sites to record changes in skin redness. On the next day, the skin response will be evaluated. Participants in the control group will be asked to avoid UV radiation by wearing hats and clothing, and using sunscreen. They will be given the doxycycline, an antibiotic, and undergo procedures with UV light shined on small areas of the skin, on the buttocks. Control participants will have 7 study days, with visits lasting from 1 to 3 hours and probably not exceeding 8 hours. They will have two shave biopsies on Study Day 2 and on Study Day 7 to determine how the skin has responded to UV light exposures. ...

The purpose of this study is to evaluate the pharmacokinetics of a single dose of daptomycin in patients aged 2-17 years old who have a suspected or proven gram-positive infection for which they are receiving standard antibiotic therapy. The tolerability of a single dose of daptomycin in these patients will also be assessed.
