Active clinical trials for "Infections"

This is a prospective specimen collection study targeting patients presenting with Influenza Like Illness (ILI) and/or Acute Respiratory Infection (ARI) in an out-patient setting. A non-invasive, user friendly sampling technique, using midturbinate flocked swabs will be used. These nasal swabs will be collected in different volumes of viral transport media (0.5mL and 3.0mL), for different dilution range of the viruses present in the collected biological specimen. The collection of nasal swabs samples will support the optimization of point of care detection methods for respiratory viruses responsible for ILI and/or ARI.

This study is to investigate clinical utility of beta2 microglobulin as an early marker for renal dysfunction caused by Tenofovir in Vietnamese HIV-infected patients.

The purpose of this study is to study the prevalence of EBV, HCMV, HHV-6 in saliva and on the toothbrush patient with periodontitis.

We aim to study if pathological NETs formation could be the underlying pathology among patients with recurrent infections and a normal screening of the immune system.

Current standard of practice in study institution dictates day of surgery urinary catheter removal in general thoracic surgery patients receiving thoracic epidural analgesia. The investigators hypothesize that this practice results in low recatheterization rates secondary to urinary retention and low urinary tract infection rates.

The immune response to Helicobacter pylori (Hp) importantly determines the pathogenesis of infection as well as the success of antibiotic eradication of the bacteria. The investigators want to demonstrate the importance of cathepsin X (CTSX), a cysteine protease, for the Hp eradication success. The diversity of the innate immune response to H. pylori antigens leading to either successful eradication of the infection or maintenance of chronic inflammation is connected to CTSX. The aim of this study is to determine whether H. pylori suppresses the CTSX expression and cytokine secretion in macrophage cell line THP-1 in the individuals that are not capable of eradicating the infection, opposite to H pylori in patients with successful H pylori eradication . The investigators also investigate the possibility whether strain-dependent differences in H. pylori lipopolysaccharide (LPS) influence the CTSX expression and cytokine secretion.

To determine if daily bathing with chlorhexidine impregnated washcloths will reduce the incidence of MRSA and VRE within an Intensive Care Unit (ICU) or ward setting.

The objectives of the study were: To study risk factors for colonization and infection with antibiotic resistant bacteria among patients with severe IAI before and after antibiotic treatment and surgical intervention. To study species changes in the rectal flora among patients with severe IAI before and after antibiotic treatment and surgical intervention. To review guidelines for antibiotic use in participating units. To evaluate surgical antibiotic prophylaxis and treatment in relation to risk for colonization and infection with antibiotic resistant bacteria among patients with severe IAI To use the results from the study in the process of a more appropriate use of antibiotics in participating units and care of patients with severe IAI. To study the dynamics of extended-spectrum beta-lactamase producing and wild-type Enterobacteriaceae in patients with suspected severe intra abdominal infections before, during and after antibiotic treatment.

Infections are common causes of morbidity and mortality in pediatric cancer patients. Today, there are limited data on the incidence, distribution of specific infections, causative agents and risk factors for severe infections in this population. Moreover, little data exist on the epidemiology of infections among pediatric patients with solid tumors. The objectives of the present study are to define the incidence, categories of infections by organ systems, etiologic agents and risk factors for infections in different pediatric malignancies. The results of this study will help the investigators to better understand the epidemiology of infections in the different types of pediatric malignancies, enable the investigators to identify high risk patients, and design a better approach to empiric treatment of these patients. A prospective, multi-center study, conducted in 5 pediatric hematology-oncology units across Israel (Rambam Medical Center, Haemek Medical Center, Schneider Children's Medical Center, Hadassah Medical Center, Soroka Medical Center). All children aged 0-18 years of age, newly diagnosed with cancer and admitted to day care or inpatient departments with fever of >38.0 C will be included in the study. Demographic, clinical and microbiological figures will be collected in each center by a research assistant supervised by the infectious disease specialist. Data will be collected according to a pre-defined Patient Data Form and entered into an electronic data base that will be analyzed accordingly. In each event of febrile episode during chemotherapy, the following data will be collected by a research assistant using a patient data form and computerized software: Demographic data: age, gender, ethnicity. Clinical data: Underlying disease, immunizations, prophylactic antibiotics, presence of central venous catheter, intensity of chemotherapy, duration of fever, duration and severity of neutropenia, diagnosis of present event. Imaging data Microbiological data Outcome The statistical analysis will be performed by an epidemiologist and statistician using the SPSS 12.0 software.

Corneal diseases are a major cause of blindness worldwide, and corneal infections are a substantial cause of blindness in Asia. The aim of the Asia Cornea Society Infectious Keratitis Study (ACSIKS) is to study infectious keratitis (corneal infections) in Asian countries, so as to improve strategies for prevention and treatment, and to reduce the burden of blindness in Asia. The first phase of ACSIKS is an 18-month observational study involving 11 eye hospitals in 8 Asian countries; these hospitals manage more than 6700 cases of corneal infections every year. From the first quarter of 2012, all patients with a corneal infection will be recruited and a standard ACSIKS protocol will be applied; this protocol includes the use of a common set of study forms and a suggested panel of microbiological examinations. However, each centre will be continue to treat their patients with the anti-infective therapy standard for their centre. Data will be recorded for each patient for a period of six months, including their medical and surgical management, the final clinical outcome and vision. Bacterial and fungal growths from patients will also be stored for further research during a second phase of ACSIKS. These studies will focus on evaluating the resistance of the most common bacterial infections to the current available antibiotics, performing DNA testing to compare our strains with bacterial infections in the West, and to developing new diagnostic tests and anti-infective therapies tailored to corneal infections in Asia.
