Active clinical trials for "Infections"

This non-interventional study aims to determine whether there is a correlation between the Fc receptor polymorphism (FcR) and the course of the disease following HIV infection.

The objective of this study is to document the residual burden of acute upper respiratory infections (AURIs), acute lower respiratory infections (ALRIs), otitis media (OMs) and auditory functional and anatomical abnormalities in children under the age of 5 years in Nunavik who will be exposed to PHiD-CV in combination with PCV-7 or PCV-13. The comparison groups will be the cohorts of children who received no PCV vaccine (those born in 1994-1996) and those exposed to PCV-7 exclusively (those born in 2003-2007).

The current protocol desires to implement a large-multicenter observational study of hospital acquired infection in ICU in China. The study will generate data on generate data about the epidemiology current management of nosocomial infection.

Permanently implantable venous ports (Port-A) is very important to patients receiving chemotherapy. It not only provides a reliable route to administrate intravenous drugs, and it also requires minimal care when it is not in use. However, catheter related blood stream infection(CRBSI) is one of the serious complications of Port-A. The diagnosis of CRBSI relies on limited tools, including blood culture or symptoms and signs of active infection. In the stage of CRBSI, Port-A removal is necessary and pose the risk for the patients to re-implant the Port-A. Thus, it is crucial to early detect the infection and give appropriate treatment. Among the pathogens, some pathogens are related to skin contaminants. Before systemic spreading, these pathogens may colonize or cause minor infection subcutaneously. This investigation is to utilize a non-invasive dual spectrum infrared imaging system to evaluate the Port-A wound and to detect the infection. Aim: 1. To build the database of infra-red thermal images of Port-A wound healing. 2. To investigate the thermal images of skin contamination related CRBSI and to compare with the thermal images of the CRBSI of unknown foci

Parts of patients are diagnosed as H. pylori -negative before ER, whereas the specimens become H. pylori-positive after ER, which may have a role in the recurrence of EGC. Our study aims to determine the difference in H. pylori infection rate of EGC patients before and after ER , and discuss the causes leading to the difference, which can provide references for improving the diagnostic accuracy of H. pylori infection and reducing EGC's recurrence rate.

To follow-up the latent tuberculosis infection and evaluate the risk of developing active tuberculosis in patients with severe chronic kidney disease or receiving long-term dialysis

The study is the WP4 of the EU-funded (7th FW) project SATURN (Impact of Specific Antibiotic Therapies on the prevalence of hUman host ResistaNt bacteria). A total of 6 surgical and 6 medical wards will participate in the study. Sites of the study are located in 3 countries (Italy, Serbia, Romania). This WP will compare nosocomial acquisition rates of methicillin-resistant Staphylococcus aureus (MRSA) and extended-spectrum beta-lactamase (ESBL)-producing gram-negative bacteria (E.coli, Klebsiella spp. and Proteus spp.) among different treatment groups and define the temporal relationship between the start of antibiotic therapy, the acquisition of new colonisation in patients previously not colonised, and the development of a bacterial infection caused by the same strain isolated in a screening sample. This goal will be achieved by completing the following primary objectives: To determine the rate of acquisition of target antibiotic-resistant bacteria by 1,000 antibiotic-days according to different classes of antibiotics, duration of therapy and antibiotic combination (monotherapy versus combination therapy); To determine genotypic relation between colonising and infecting strain in the same patient and patients' and hospital staff colonising strains (to be performed in collaboration with WP1 of the SATURN project); To study the virulence and fitness of the isolates (i.e. new colonising strains) causing subsequent nosocomial infections (to be performed in collaboration with WP1 of SATURN project); To predict the risk for nosocomial infections due to target bacteria after a single treatment therapy adjusted by length of hospitalisation and ward colonisation pressure.

The incidence of pin site infection is related to the nursing management of external fixation.

The purpose of this observational, exploratory study in patients undergoing any cardiac valve replacement or repair is to assess the rate of bacterial colonization over native degenerative calcified cardiac valves.

Enterovirus and herpes simplex viruses 1 and 2 are the main causative agents of central nervous system infections. Instead, the role of lymphocytic herpesviruses in the etiology of central nervous system (CNS) infections is not clear, even if there is the positive cerebrospinal fluid (CSF) polymerase chain reaction (PCR)-result for the virus. The aim of this study is to evaluate the presence of DNA from lymphocytic herpesviruses in the CSF obtained from the immunocompetent patients with CSF pleocytosis and from the patients with normal CSF leukocyte count.
