Active clinical trials for "Infections"

RATIONALE: Gathering information about human papilloma virus (HPV) infection in HIV-positive men who have sex with men may help doctors learn more about the disease. PURPOSE: This clinical trial is studying HPV infection in HIV-positive Indian men who have sex with men.

The objective of this study was to obtain data on the safety, tolerability and compliance with Zithromax in children with bacterial infections of the upper and lower respiratory tract.

Background: Fungal infections of the lung (pneumonia) can be caused by molds, such as Aspergillus and Zygomycetes, but these causes are often difficult for a doctor to diagnose. Early and accurate diagnosis of these infections can help doctors to select the correct medicines for proper treatment. A number of methods are used to diagnose fungal pneumonia. Ones that are commonly used in clinical practice include radiographic imaging (chest X-rays and computed tomography (CT) scans), blood tests, and cultures taken from fluid from the lungs (broncho-alveolar lavage (BAL) fluid). Other new methods may improve the diagnosis of fungal pneumonias. These methods include tests that can detect DNA from the fungal germ in blood and BAL fluid of some patients with these infections. Objectives: To help develop better and more accurate methods of diagnosing fungal lung infections. To detect fungal DNA and chemicals in the bloodstream and BAL fluid of immunocompromised patients with pneumonia. Eligibility: - Immunocompromised patients who are currently enrolled in another NIH protocol and who have a CT scan that shows a possible fungal infection of the lung. Design: Researchers will review patients' existing medical records and CT scans, and current pneumonia treatment plans. Patients will provide blood and BAL samples for the duration of their treatment for pneumonia, as required by researchers. Additional CT scans will not be performed, except as part of existing treatment plans.

The purpose of this study was to determine if the use of daily chlorhexidine bathing would decrease the incidence of MRSA and VRE colonization and healthcare associated Bloodstream Infections (BSI) among Intensive Care Unit (ICU) patients.

The purpose of this study is to evaluate the drug concentrations in the conjunctiva and aqueous humor of AzaSite™ compared to Vigamox® in subjects undergoing routine cataract surgery

To assess the efficacy and safety of Tygacil in the usual German hospital setting. The main goals are: to assess the efficacy of Tygacil under usual care conditions (cure rate); to assess the main side effects observed in daily medical practice (Safety of Tygacil); to determine whether patients are optimally dosed with Tygacil (according to the label) and the proportion of patients receiving a monotherapy versus combination therapy; to observe the potential resistance development against Tygacil in Germany; to determine which antibiotic agents are chosen for a combination therapy with Tygacil; to determine to which antibiotic substance non-responders to Tygacil are switched; to assess the duration of the intravenous therapy with Tygacil and to determine whether and which patients receive an oral antibiotic substance after the therapy with Tygacil; to collect information on profile, comorbidities and characteristics of patients treated with Tygacil.

The purpose of this protocol is to provide a mechanism for the ongoing collection of blood and urine samples in newborns that will be used to measure levels of antimicrobial products used in the newborn population where there are limited pharmacokinetic data in either premature or term infants.

This study argues that H.pylori infection, by increasing the production of reactive oxygen species, increases the utilization of dietary antioxidants(Vit E and Vit C) that serve in quenching the free radicals, thus decreasing their serum levels and confounding their protective effect against gastric cancer.

This is a non-comparative, open, multisite prospective estimation study to evaluate the efficacy and safety of caspofungin in the prophylactic treatment of adults who have received an orthotopic liver transplant and are at high risk of developing an invasive fungal infection. It is expected that the proportion of high-risk liver transplant recipients who develop a documented (proven or probable per European Organization for Research and Treatment of Cancer/Mycoses Study Group [EORTC/MSG] modified criteria) invasive fungal infection during the first 100 days after the onset of prophylaxis with caspofungin will be lower than 15%. It is also expected that the incidence of serious drug-related adverse events will be less than 25%.

This study, conducted by NIH and the University of Bamako in Mali, Africa, will study the effect of concurrent infections with malaria and filariasis on patients' immune response. Lymphatic filariasis is caused by infection with very small parasitic worms called Wuchereria bancrofti that are acquired from mosquitoes. The worms may cause no illness in many who are infected, but is some, they can cause swelling of the arms, legs, breast and genitalia, which may progress to permanent swelling referred to as elephantiasis. Malaria is caused by Plasmodium falciparum, another parasite that is spread by mosquitoes. It can cause fevers, headaches, body aches and weakness, and, if untreated, it can cause severe illness and death. The 8-month study will analyze measures of immune function in blood cells from people with or without filarial infections who become infected with malaria. The goal of the studies is to see if having a filarial worm infection affects immunity against malaria. Results of analysis of immune function in persons with malaria but without filaria infections will be compared with those harboring both filaria and malaria infections and also with results from healthy control subjects. Healthy individuals and patients with malaria and filarial infections between 1 and 8 years of age and between 18 to 65 years of age who live in N'Tessoni and healthy individuals living in Bamako, Mali (controls), may be eligible for this study. Participants have blood samples collected as follows during the study: A blood sample will be collected at the beginning of the study. Individuals found to have the filarial worm infection have a second sample drawn at nighttime when the filarial worms are present in the blood. Treatment for filaria infection will be offered to all infected individuals at the end of the study. A second sample will be collected during malaria season. Subjects will be interviewed about their health during the malaria season and re-tested for filarial and malaria infections with a finger-prick test. Those who test positive for malaria will be offered treatment to begin immediately after collection of the donated blood sample.. A third sample will be collected after the end of the malaria season. Subjects will be interviewed again about their health and re-tested for filarial and malaria infections with a finger prick test. Those who have positive results for either infection will be offered treatment after collec...
