Active clinical trials for "Infections"

To investigate the role of chronic infection as a risk factor for vascular disease in a study of Native Americans. The primary focus is on the two most common agents Chlamydia pneumoniae and cytomegalovirus with a secondary emphasis on Helicobacter pylori.

This study evaluates patients infected with both HIV and Hepatitis C virus (HCV) who are receiving anti-HIV drugs. The purpose of this study is to learn more about HCV infection in patients whose HIV blood level decreases to less than 500 copies/ml.

Invasive fungal infections have a major impact on the morbidity and mortality of immunocompromised patients, including patients with hematological malignancies, neutropenic patients, human immunodeficiency virus infected patients, diabetics, solid organ transplanted patients and patients admitted in an intensive care unit. The survival of these patients depends on early diagnosis and prompt appropriate antifungal treatment. The early diagnosis of these infections is difficult because of the lack of sensitive test methods, notably blood cultures. For these reasons, the investigators decided to develop a real-time PCR (Polymerase Chain Reaction) assay on blood samples. It should allow rapid response to establish a positive or negative diagnosis of invasive fungal infection, could contribute strongly to the decision of treating using antifungals, and should monitor the effectiveness and the optimization of antifungal prescriptions. The investigators' objectives are: First, to validate an extraction method from blood infected by fungi species. Secondly, the investigators want to develop three real-time PCR: A fungal real-time PCR able to detect most fungal species; a real-time PCR targetting Candida albicans and Aspergillus fumigatus which are two clinically important pathogens. Then blood samples of patients (classified according to EORTC consensus) will be collected during the study in order to evaluate and validate our method on clinical samples. Results will allow the investigators to determine the sensitivity, specificity and reproducibility, negative and predictive values. Overall, the investigators' work aims to evaluate the clinical impact of real-time PCR in the early diagnosis of invasive fungal infections and on the initiation or stopping of antifungal therapy. The economic impact resulting from the use of this method will be evaluated.

The aim of this trial is to evaluate the safety and virological and immunological efficacy of Aptivus in treatment-experienced patients with advanced HIV-1 infection who had developed resistance to more than one protease inhibitor.

The virological efficacy will be no different in children treated with single versus double boosted PI second line ART regimens.

Pneumonia is a frequent complication of acute stroke and is associated with increased mortality and long-term impairment in the affected subjects. In previous studies, a number of clinical (e.g., dysphagia, severe neurological impairment, mechanical ventilation), radiological (e.g., large infarctions in the territory of middle cerebral artery, insular infarction) and biochemical (e.g., increased serum levels of C-reactive protein, decreased levels of CD4+ T-lymphocytes) findings have been reported as risk factors of stroke-related chest infection. The present study (PRECAST) aims to identify a small set out of these previously described risk factors that can predict stroke-related pneumonia with high sensitivity and specificity.

The trial will randomise HIV/HBV co-infected individuals to different HBV-active antiretroviral therapy treatment regimens.

The objectives of the study are to determine the prevalence of respiratory virus infections in COPD patients, during and outside acute exacerbation to explore the impact of these viral infections on the outcome of these patients to explore the association between blood procalcitonin levels and viral infections in this population.

According to the Israeli Ministry of Health requirement, this study was designed to evaluate the efficacy of the UroShield system is patients that require urinary catheterization. This was designed to compare standard treatment (urinary catheter alone) with the UroShield treatment in occurrence of catheter associated Urinary Tract infection, pain, discomfort, Biofilm prevention and trauma.

The association between the levels of d-dimer, fibrinogen and PAI-1 in plasma of elderly patients admitted to internal medicine departments because of infection and the occurrence of cardio- and cerebro-vascular disease after discharge
