Active clinical trials for "Communicable Diseases"

Serological surveys measuring anti-severe acute respiratory syndrome coronavirus 2 (anti-SARS-CoV-2) antibodies in the population to assess the extent of the infection and the COVID-19 immunity of the population in French Guiana.

People living with HIV (PLHIV) who require admission to hospital in WHO Africa region have poor outcomes. TB is very common in this group, but can be difficult to diagnose. The CASTLE trial aims to determine whether systematic screening for tuberculosis using digital chest X-ray with computer-aided diagnosis (DCXR-CAD) plus urine lipoarabinomannan testing with Fujifilm SILVAMP TB LAM (FujiLAM) plus usual care can improve admission outcomes for hospitalised PLHIV, compared to usual care alone. Our study is a single centre, unblinded, cluster-randomised (by day of admission) trial of DCXR-CAD plus FujiLAM plus usual care vs. usual care alone for screening for TB in unselected adult PLHIV admitted to a district general hospital in Malawi. The primary outcome is the proportion of people starting TB treatment by the time of death or hospital discharge. The secondary outcomes are all-cause mortality at 56 days from enrolment, proportion of people starting TB treatment within 24 hours from enrolment, and proportion of people with undiagnosed TB. In the CASTLE study we collect a single sputum sample for M. tb culture from participants and undiagnosed TB specifically refers to a person who did not start TB treatment by the time of death or discharge from hospital and has a M. tb cultured from their sputum sample. Alongside the two trial arms, a third smaller diagnostic cohort arm (1 in 9 of admission days / trial clusters) will explore the range of underlying infectious pathology. The diagnostic cohort does not contribute to trial outcomes.

This observational study evaluates whether lung sound analysis with LungPass device can be used to differentiate upper and lower respiratory tract infections (URTI and LRTI)

This study aims to use a clinically validated metagenomic next-generation sequencing (mNGS) assay to provide a demonstration of precision medicine for diagnosis of acute infectious disease in hospitalized patients. From June 2016 to June 2017, 200 patients will be enrolled from multiple hospitals in California and outside of California. Patients will be evaluated to determine the impact on the mNGS assay on diagnostic yield, hospital costs and clinical outcomes.

The purpose of this study is to determine if oral vancomycin used as primary Clostridium difficile prophylaxis can reduce the incidence of this infection in high-risk patients.

Alcohol is used to disinfect the skin prior to injections in order to prevent infections caused by bacteria on the skin being injected within tissue. At present, however, clinical trials do not demonstrate a clinical impact of using or not using alcohol swabs on infections and infection symptoms calling into question the practice of using it prior to all injections. These studies are methodologically flawed, and do not specifically examine vaccine injections. The present study is being undertaken to provide some preliminary data for the risk of infection and infection symptoms when alcohol swabs are not used to perform vaccine injections.

Catheter related infection is a frequent and life threatening event in ICU. A chlorhexidine impregnated sponge has been proven to reduce the rate of major catheter related infections in ICU patients (HR=0.39, p=0.03) (Timsit Jama 2009). However, dressings are detached in 40% of cases before planned changes and the rate of unplanned dressing is significantly associated with the major catheter related infections. Primary objective: To demonstrate that Tegaderm CHG, a new CHG impregnated dressing decrease the rate of major catheter related infection as compared to non impregnated dressings and to demonstrate that highly adhesive dressing decrease the rate of detached dressings. Secondary objectives: To demonstrate that the use of high performance dressing decrease the rate of unstuck dressing and the rate of catheter infections. To evaluate the tolerance of CHG impregnated gel dressings (Tegaderm CHG). To calculate the cost saving of each dressings

This is a comparison, at this VA Hospital, of standard operating room management in colorectal surgery to a more rigid management using an additional five previously tested treatments to determine if this changes the rate of post operative wound infections.

Background: Vitamin D has been shown to be an important immune system regulator. Vitamin D insufficiency during the winter may cause increased susceptibility to infections, particularly viral upper respiratory tract infections (URIs). Objective: To determine whether vitamin D supplementation during the winter season prevents or decreases URI symptoms in adults. Methods: A randomized, double-blind, placebo-controlled trial was conducted in 162 adults. Participants were randomized to receive vitamin D3 50 mcg (2000 IU) daily or matching placebo for 12 weeks from December 2006 to March 2007. A biweekly questionnaire was used to record the incidence and severity of URI symptoms

The purpose of this study is to evaluate whether isoniazid can safely (and further) reduce the risk of tuberculosis in HIV infected people receiving HAART.
