Active clinical trials for "Infections"

There has been considerable debate over the last 30 years about the interaction between asthma and parasitic infection. It has been suggested that at least part of the reason for the increasing prevalence of asthma in the developed world is a decrease in parasite infections resulting from improved living conditions with economic development. Our previous studies in Ethiopia suggest that hookworm infection may be particularly important in this process. To establish definitively whether parasites can protect against allergic disease, and specifically asthma, ultimately requires a randomised clinical trial of parasite infection in patients with asthma. We, the researchers at the University of Nottingham, have completed a study in normal volunteers to establish the dose of hookworms necessary to generate infection at the level shown to be protective in population surveys, and shown that infection is well tolerated. In addition, we have recently completed a randomized placebo-controlled clinical trial of hookworm infection in allergic patients with rhinitis which showed that there was no negative effect on bronchial responsiveness during the phase in the lifecycle where the hookworm larvae migrate through the lungs. Consequently, are now proceeding with the definitive randomized placebo-controlled trial of hookworm infection in people with asthma. This study will also provide us with the opportunity to investigate the cellular mechanisms of the effect of hookworm infection on the immune system.

Studies for GSK580416 have been completed in rats and dogs. The main toxic effects seen in animals affected the digestive system and blood cells. Study OPS106400 will be the first administration of GSK580416 in humans. Parts A and B of this study will examine the safety, tolerability, and pharmacokinetics of increasing single doses of GSK580416 with reference to placebo. Part C of the study will assess the effect of food on the safety, tolerability, and pharmacokinetics of a single dose of GSK580416 in healthy subjects.

multicenter, randomized (1:1), semi-single blind study comparing the safety and efficacy of HDSD daptomycin (10 mg/kg q24h for 4 days) with that of comparator (vancomycin +/- SSP for 7-14 days) in patients with cSSSI due to Gram-positive bacteria. Patients will be randomized on a 1:1 basis to receive either daptomycin 10 mg/kg i.v. q24h for 4 days or vancomycin 1 g. q12h for up to 14 days.

At the end of 2004 there were more than 40 million people infected Worldwide with HIV, with an estimated 16,000 new infections every day (UNAIDS, 2004). The HIV epidemic threatens whole societies particularly in Africa and Asia and rates of infections in the Western Countries have also increased over the last few years. However, despite more than 15 years of research, an effective vaccine against HIV and acquired immunodeficiency syndrome (AIDS) has still not been developed. There is considerable evidence that cellular immune responses can effectively control HIV-1 replication during acute and chronic infections thereby possibly protecting individuals from infection and preventing the spread of HIV. To be truly effective in the general population, a vaccine must induce responses specific to immunologically conserved regions. The epitope-based vaccine MVA-mBN32 represent a very logical approach to this problem because its potential to elicit a polyfunctional immune response and to focus these responses to conserved epitopes. In this study the safety, tolerability and immunogenicity of a recombinant MVA-BN® expressing CTL and HTL epitopes of HIV-1 (MVA-mBN32) vs. the vector control MVA-BN® in 30 HIV-infected subjects will be examined. This will include a full analysis of CD4+ T helper cells and CD8+ CTL responses to these epitopes, to establish the potential of such a homologous prime-boost vaccine approach to induce a broad cell-mediated response to different HIV antigens.

This study will evaluate the acceptability and safety of famciclovir in infants with herpes simplex infection

This study will determine whether pioglitazone (Actos, a drug approved to treat diabetes, can benefit HIV-infected people with fatty liver. Fatty changes of the liver (also known as steatosis) have been linked to diabetes and long-term liver damage in some patients. Pioglitazone has been shown to improve fatty liver in people without HIV; this study will see if it is beneficial for people with HIV as well. HIV-infected patients 18 years of age and older with increased fat in the liver may be eligible for this study. Screening includes a CT scan and liver biopsy (withdrawal of a small sample of liver tissue through a needle). Participants are randomly assigned to take either 45 mg of pioglitazone or placebo (sugar pill) by mouth once a day for 48 weeks. At the end of 48 weeks, all participants stop taking their medication and are followed for an additional 48 weeks to see what, if any benefits, of pioglitazone persist after treatment is stopped. In addition to taking the study medication, participants undergo the following procedures: Visits to the NIH Clinical Center over a period of approximately 2 years at day 0 and weeks 2, 8, 16, 24, 32, 40, 48, 52, 72, and 96. Most visits take about 1 hour and include blood drawing for various laboratory tests. Insulin clamp test at day 0 and weeks 24 and 48 to see how the body processes glucose. This test takes 4 to 6 hours and may include an overnight stay at the Clinical Center. A catheter (plastic tube) is placed in a vein in the arm to infuse insulin and another is placed in a vein on the back of the hand to draw blood samples. Blood sugar is checked frequently and glucose is given to keep blood sugar at normal values. Nutrition evaluations at day 0 and weeks 24 and 48. Subjects write down all the food they eat and drink for 4 days before the visit. They meet with a nutritionist to review the food record and to complete simple measurements of body fat and shape. CT scan of liver and abdomen at weeks 24, 48, 72 and 96. Liver biopsy at week 48.

After spinal cord injury, patients have frequent urinary tract infections (UVI). Vitamin C is usually prescribed to prevent such infection, but the efficacy of the treatment is poorly documented. In the study, patients will be randomised either to receive vitamin C daily, or not, for one year, and clinical episodes of UVI will be registered. The null hypothesis is that vitamin C will not reduce the number of UVI episodes by 30%.

Objectives: To find out if the chance of developing a serious illness or of getting AIDS is less if patients start taking HIV medicines at a time when their cluster-of-differentiation-4 (CD4)+ cell count is still fairly high, instead of waiting until the CD4+ count is at the level where there is good evidence for starting medicines. To learn more about how a strategy of starting HIV medicines early might affect other aspects of care, such as the chances of developing other illnesses or resistance to HIV medicines, the frequency of doctor visits, the cost of medical care, and general health and satisfaction.

This study aimed to compare the efficacy of pin-tract infection prevention between silversulfadiazine and dry dressing. Methods: 30 patients with an open tibial fracture admitted to Songklanagarind hospital from September 2007 to June 2008 and treated by emergency debridement and external fixation were randomized into two groups, one treated with silversulfadiazine for infection prophylaxis (15) and a control group treated with dry dressing only (15). All patients were followed until the external fixator was removed. Pin-site infections were assessed and graded at each follow-up visit by an orthopaedist blinded to the mode of treatment. A culture from the pin site was done if an infection occurred.

This is a multi-center, open-label, non-randomized proof-of-concept trial. Two cooperating HIV-specialized centres represented by Dr. med. Hans Jaeger and Prof. Dr. Johannes Bogner are planning to perform an IIT (investigator initiated trial) with the goal to eradicate HIV in N=40 HIV-infected patients with either primary infection or chronic infection and successful HAART (Highly Active Antiretroviral Treatment) of several years. All patients will be started on a multi-drug HAART including two Nucleoside-Reverse-Transcriptase-Inhibitors (NRTI´s), one Protease-Inhibitor (PI), a CCR5-inhibitor and an Integrase-Inhibitor (INI). Decay of viral reservoirs like latently HIV-infected CD4+ T-cells will be monitored over time.
