Filter by:This study will further evaluate the ACAM-CDIFF™ vaccine in a population of middle-aged to elderly individuals at risk of exposure to Clostridium difficile because of impending hospitalization or residence in a care facility. Primary Objectives: - To describe the safety profile of subjects in each of the study groups. - To describe the immune responses elicited by toxoid A and toxoid B of subjects in each of the study groups. Observational Objective: - To describe the occurrence of first-time Clostridium difficile infection (CDI) episodes.
The PIVOT trial aims to determine whether a strategy of switching to PI monotherapy is non-inferior to continuing triple-therapy, in terms of the proportion of patients who maintain all the drug treatment options that were available to them at baseline after at least 3 years of follow-up, and to compare clinical events, safety, toxicity and health economic parameters between the two strategies.
In recent years, several new methods for treatment of catheter-related bloodstream infections (CRBSI) such as antibiotic or antiseptic lock-therapy have been developed with variable success [1-10]. Long-term tunnelled central venous catheters provide a reliable access for administration of chemotherapy, parenteral nutrition or haemodialysis. However, they are not free of complications such as bacteremia. The need to preserve these intra-vascular devices as long as is possible in patients in whom conventional treatment was failed makes emerge antibiotic lock-technique. Ethanol lock-therapy was demonstrate her utility in this cases. But no study has yet been published using the ethanol lock-therapy as a prophylactic therapy in catheter related infections, neither her application in short-term CVCs. Objectives: To investigate the value of a ethanol-lock solution in the prophylaxis of non-tunnelled short-term CVC related infections in a heart post-surgical intensive care unit (HPSICU). Methods: An academic, prospective, randomized and controlled clinical trial is proposed. Patients at HPSICU who have a CVC more than 48 h will be randomized in two arms (ethanol-lock or control group with conventional measurements such as anticoagulants). In the follow-up period, we will register all necessary data to evaluate the end-points of study (CBRSI rate, catheter colonization rate, hospital stay, antimicrobial consume and adverse events due to ethanol).
Infections pose a serious threat to cancer patients in chemotherapy. Prompt diagnosis and treatment is of paramount importance as infections may be life-threatening in immune-compromised individuals. Traditionally, the C-reactive protein (CRP) has been used as a marker of infection. However, the CRP is also often elevated in cancer patients and as a marker CRP may be unreliable in cancer patients. Other markers for infection includes procalcitonin which has been showed to be of some value for the diagnose of bacterial infections. This study examines procalcitonin as a potential marker of bacterial infection in cancer patients.
Recurrent CDI is a growing problem with few treatment options that provide lasting effect. Fecal transplantation has been shown in several case series to be successful in controlling recurrent CDI. The current study is a non-blinded, randomized controlled trial comparing fecal transplantation with a 6 week taper of oral vancomycin for the treatment of refractory CDI. Approximately 146 patients will be enrolled over one year. Participants in the study will be followed for 120 days, and will be given the opportunity to cross over to the alternative intervention arm if a relapse in symptoms occurs. The primary outcome measure will be recurrence of toxin-confirmed CDI within 120 days of starting the intervention. Secondary outcomes include: early recurrence of symptoms within 14 days, relapse within 120 days (same strain of C. difficile), attributable mortality, hospitalization and serious adverse events.
Cervical cancer is a public health problem. In term of frequency and mortality, it represents in Martinique the third localization the most frequently diagnosed and the fifth cause of death by cancer. Cervical cancer is recognized as viro-inducted. Human papillomavirus (HPV) is the etiologic agent, as a necessary but not sufficient cause, in the cancer genesis. It is estimated than about 70 to 80% of women have been or will be infected with an HPV in their genital life, the risks factors being those of the others sexually transmitted diseases (STD). Most of HPV infection are transient, by spontaneous clearance in a few months of the virus under episomal form. Carcinogen risk is related to viral persistency which inducts the condition of cellular transformation. Infection persistency and subsequent carcinogen risk depend of the genotype concerned and of the host immunitary response. HIV infection is known to be associated with an higher prevalency of one or several infection with HPV-HR. However, no data about HIV/HPV coinfection prevalency are available nowadays in French overseas department of South America whereas they are the most affected by HIV.
The aim of the interventional study is to compare the different treatment modalities in reducing erythema size and rate of resolving phlebitis.
Experimental and clinical studies in adults have reported that green tea catechins prevent influenza infection. In this clinical randomized study, the investigators aimed to determine the effects of gargling with green tea on the prophylaxis of influenza infection among high school teenagers.
Bacterial infections are a common complication in patients suffering from burns. These infections can cause significant morbidity and often mortality. Antimicrobial resistance coupled with the prevalence of burn-related infections warrants the identification of alternative substances in the treatment of burn-related infections. The cranberry has been examined as a potential agent in the prevention of other types of infections and it appears to have anti-adherence effects on bacteria. In addition, the cranberry has demonstrated general inhibitory effects against some types of bacteria suggesting that it may be a useful agent in the prevention of bacterial infections in burn patients. The purpose of the present study is to investigate the effect of cranberry extract on the incidence of infections in burn patients.
Hypothesis: a combined strategy of tuberculin skin test (TST) followed by QuantiFERON-TB Gold In-Tube (QFT-IT) to confirm positivity (tuberculosis infection,in contact-tracing study will allow avoiding unnecessary preventive treatment without increasing rates of tuberculosis cases among contacts screened. Aim of the study: to compare a combined strategy of the TST and the QFT-IT with TST alone for the diagnosis of tuberculosis infection and for therapeutic decision in contact tracing study. Design and setting: Prospective, multicentre, comparative study in 12 hospitals in Spain. Study population: 870 subjects, household contacts of patients with culture positive pulmonary and/or laryngeal tuberculosis will be randomized to one of two strategies: Arm A (standard practice), in which treatment decisions will be based on the TST result, and Arm B (experimental), in which treatment decisions will be based on the QFT result. Interventions: participants in arm A will undergo TST; participants in arm B will undergo TST, and, in case of a positive result, QFT-IT as well. Participants with positive TST (arm A) and positive QFT-IT (arm B) will be diagnosed with tuberculosis infection and will be treated with isoniazid for 6 months. All participants will be followed for two years. End-points of evaluation: development of tuberculosis and proportion of subjects for whom treatment is prescribed in each arm.
