Active clinical trials for "Infections"

The purpose of this study is to compare duloxetine with conventional treatment of pain in HIV-1 infected patients.

The purpose of this study is to determine whether TD-1792 is safe and effective when used to treat complicated skin and skin structure infections caused by Gram-positive bacteria.

This is a randomized double-blind three-arm trial to evaluate two dosages of CVT-E002 against placebo in pediatric upper respiratory tract infections (URTI). It is hypothesized that CVT-E002 use at standard doses reduces the duration of URTI in children aged 3-12 years.

Infections are the important cause of high mortality in young infants in developing countries. Zinc is a crucial micronutrient as it influences various immune mechanisms and modulates host resistance to several pathogens. It has shown benefits as an adjunct therapy in infections like diarrhea and pneumonia in older children Given the predisposition of young infants in developing countries to zinc deficiency and infections, addition of zinc to standard treatment of serious bacterial infections may lead to significant improvements in the outcomes. Several hypotheses will be examined in this clinical trial. The primary objective is to measure, in a double blind randomized controlled trial, the efficacy of giving 2 RDA (Required Daily Allowance 10 mg) of zinc orally in addition to routine antibiotics, for treatment of possible serious bacterial infection in infants >= 7 days and up to 4 months of age in reducing the proportion of treatment failures and time to discharge from the hospital. This will evaluate the clinical consequences of the possible immunomodulation by zinc supplementation. This is critical to demonstrate because nearly 80% of infant mortality occurs in first months of life. Young infants with possible serious bacterial infections fulfilling the inclusion criteria will be enrolled in the study and stratified into 4 groups on basis of weight for age 'z' scores < -2 z and >=- 2 z and whether he/she has diarrhea or not. Within each stratum the subjects will be randomized to receive zinc or placebo. Treatment failures will be defined by the need for a change of initial antibiotic therapy. The minimum duration of monitoring will be till clinical recovery (using predetermined criteria). Serum copper, serum ferritin and serum transferrin receptors will be determined at enrollment, 72 hours after enrollment and at discharge from the hospital. Concentrations of CRP and procalcitonin will be measured at baseline, 72 hours after enrolment and at clinical recovery. Documentation of efficacy of addition of zinc to standard therapy may provide a simple and low-cost strategy to improve survival in serious infections in young infants. This is likely to have a significant impact on infant morbidity and mortality. It will be good example of using a simple immunomodulator beneficially in improving child health.

The purpose of this study is to compare the clinical cure rate of ceftobiprole medocaril versus a comparator in the treatment of patients with complicated skin and skin structure 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. We now propose two randomised placebo-controlled double blind clinical trials. The first will test the effectiveness of hookworm infection in reducing symptoms in allergic patients with rhinitis, and will also serve to allow us to check the likely safety of hookworm infection in asthma. Assuming that the results of this study are favourable, we will then carry out a trial of hookworm infection in asthma. We will also take the opportunity during both of these studies to investigate the cellular mechanisms of the effect of hookworm infection on the immune system.

The primary objective is to assess the safety of telithromycin (HMR 3647) (20% fine granules) 1g filling sachet in children with infections (Respiratory tract infections, Dermatological infections, Otorhinolaryngological infections, Dentistry/Oral surgery infections). Secondary objectives are to assess the clinical efficacy, bacteriological efficacy and acceptability of telithromycin (20% fine granules) 1g filling sachet in children with infections.

This will be a randomized, placebo-controlled, double-blind single-center proof of concept study to evaluate the anti-EBV activity of 4 grams of valomaciclovir (2 grams BID) for 21 days in subjects with infectious mononucleosis documented to be caused by primary EBV infection. Otherwise healthy subjects (≥15 years old) referred to us with a clinical diagnosis of primary infectious mononucleosis will be screened and those with laboratory-confirmed primary EBV infection will be enrolled.

The aim of this study is to compare the efficacy and impact on growth of two drug treatments against intestinal worms in schoolchildren from a rural area of Guatemala. According to the World Bank, these intestinal worms are one of the top causes of childhood health problems in many areas of the developing world (The World Bank, 1993). Infected children are more likely to have inadequate nutrition due to the worm infections and are more likely to be shorter in height and weigh less than children who are not infected. After collecting height and weight information, we will split the children into two groups. One group will receive albendazole and the other group will receive combined albendazole/ivermectin. Both groups will be receiving albendazole, the current standard of care treatment. Ivermection is expected to improve efficacy and nutritional benefit as well as add increased scope of treatment for the worm Strongyloides, and ectoparasites such as scabies and head lice. Both treatment regimens and the combination have been used millions of times in the developing world and are safe to use. Co-administration of drugs would be a more efficient use of the opportunity to access schoolchildren and provide deworming treatment.

Helicobacter pylori is recognized as a major gastrointestinal pathogen in developing countries. This microorganism infects up to 60% of children less than five years in those countries and is strongly associated with chronic gastritis and peptic ulcer disease in children and adults. The progression of gastritis to atrophy often leads to decreased gastric acid output, which is a well-known risk factor for anemia. Gastric acid is essential for increasing the bioavailability and absorption of non-heme dietary iron, the most important source of iron in developing countries. Numerous reports suggest that iron malabsorption secondary to low gastric acid output is a problem in developing world countries. It has been further observed that iron deficiency anemia is resistant to iron therapy particularly in these countries. In a recently completed study we observed an association of anaemia with H. pylori infection. We hypothesize that the poor bioavailability of iron in these countries could be related to H. pylori -induced low gastric acid output and we propose to investigate the role of H. pylori infection as a cause of anemia and treatment failure of iron supplementation in Bangladesh. A prospective, randomized, double-blind, placebo-controlled field trial is proposed among four groups ( 65 each) of H. Pylori infected children of 2-5 years of age with iron deficiency anemia. The children will be assigned to one of the four therapies: antibiotics alone (for H. Pylori eradication), antibiotic plus iron therapy, iron therapy alone, or placebo. Hemoglobin concentration, serum ferritin concentration, and transferrin receptor will be measured before and at 1 and 3 month after the intervention. We also propose a complementary study in an additional 20 children with H. Pylori infection and iron deficiency anemia to assess iron absorption with application of double stable isotopes. The change in hematological parameters will also be compared among the groups before and after the therapy. The results of this study are expected to have implications in the prevention and treatment of iron deficiency anemia in developing countries.
