Filter by:The purpose of this research is to investigate the efficacy of transplanting screened donor fecal material in treating patients with recurrent Clostridium difficile infection. Participants with refractory Clostridium difficile infection will be given healthy donor stool administered by colonoscopy or enema and their response will be evaluated by symptom questionnaire and stool testing for Clostridium difficile at 4 weeks after the treatment.
Circadian rhythms, which play crucial roles in physiology, are emerging as important regulators of specific immune functions. Hospitalization in intensive care unit leads to a deep impairment of circadian rhythm. Infection is a frequent event during ICU hospitalization. The investigators hypothesis is that in trauma patients the lack of circadian rhythm variations is associated with the occurrence of infection. The primary aim of the study is to assess the circadian variations of plasma Bmal1 in the occurrence of healthcare related infection during the 30 days after inclusion. The secondary aims are to assess the plasma expression of circadian genes (Clock, Cry1, Per3, and Rev-erba), the production of cytokines in plasma, and the concentration of cortisol, according to the occurrence of an infection.
Infections represent the first cause of death and of morbidity in people treated for immunologic and inflammatory diseases with corticosteroids, immunosuppressive drugs or biotherapy. Epidemiological, clinical, biological and therapeutic determinants of these infections are poorly understood. There is no recommendation for the prevention and treatment of infections in this particular field. Purpose : Recent therapeutic trials evaluating immunosuppressive and biotherapy (cyclophosphamide, mycophenolate mofetil, rituximab, belimumab) in the field of immunologic and inflammatory diseases have found a risk of severe infection of 7 to 18% during the first year after the beginning of the treatment. Thus, the main objective of the study is to describe the incidence and risk-factors for infections in people treated with such agents for immunologic and inflammatory diseases.
The purpose of this study is to determine whether MRX-I is as safe and effective as Linezolid in the treatment of adult patients with acute bacterial skin and skin structure infections
Genital HPV is the necessary cause for cervical cancer, as well as a major contributing cause of several other cancers and conditions. There are now effective vaccines against the main oncogenic HPV types, HPV16 and 18. Most research and discussion has focused on targeting the vaccine to young women and older adolescents. Based on this, a national free HPV vaccination program for adolescent girls commenced in 2007, in Australia. However, at the time of commencement, there had been no research on the use of this vaccine in immunosuppressed. Therefore, information on the immunogenicity, safety and duration of efficacy of HPV vaccine when administered to immunosuppressed children is needed. This trial looked at a 3 dose schedule of quadrivalent HPV vaccine in a range of immunosuppressed children, with the endpoint being immunogenicity, followed for 5 years for duration of immunity.
With aging of the general population and broadening indications, the number of pacemaker recipients is steadily increasing. The incidence of infections of the implanted material, a dreaded major complication, is also rising. The diagnosis is evident in presence of an abscessed pocket, cutaneous breakthrough of the pulse generator or vegetations attached to the lead. On the other hand, a proportion of patients present with less specific clinical manifestations and a pacemaker recipient may be recurrently hospitalized for an infectious disorder of unknown origin despite detailed investigations. Without proof of lead infection, removal of the system without confirmation of its infection is usually proposed, despite the known morbidity and mortality associated with the extraction procedure (0.5 to 2%). Positive culture of the leads implies that the leads were involved in the infectious process. In recent years, 18FDG-PET-CT scan has made promising contributions in different areas including imaging to detect infection at different organ sites. Absence of hyperfixation of the lead, identified by 18FDG-PET/CT scan may be an accurate sign of absence of pacing system infection. The extraction of intracardiac implanted material, when it is indicated by the current standard strategy, may result in negative bacteriological cultures in 10 to 25% of patients, even when they did not receive antibiotics before extraction. The hypothesis of the study is that a new strategy adding 18FDG-PET-CT to the current strategy may avoid or reduce these false-positives. Therefore it is hypothesized that the sensitivity of 18FDG-PET-CT will be high enough to avoid unnecessary extractions of uninfected leads, resulting in a high negative predictive value of the new diagnostic strategy incorporating 18FDG-PET-CT. The present study aims at providing valid estimates of diagnostic accuracy parameters of 18FDG-PET-CT, especially its sensitivity. For this clinical study, firstly, 18FDG-PET-CT exam will be performed in patients, with suspicion of pacing or defibrillation lead infection, hospitalized in cardiology unit; secondarily, an intervention for the extraction of the intra-cardiac material, under general anesthesia, will be practiced and then a bacteriological culture for extracted material will be required. The end of study visit is complete the last day of material extraction. The follow up will last 2 to 7 days.
Acute lower respiratory tract infections (LRTIs) account for more than 27% of all hospitalizations among US children under five years of age, with recurrent LRTIs in children a recognized risk factor for asthma. Residential biomass combustion leads to elevated indoor levels of fine particulate matter (PM2.5) that often exceed current health-based air quality standards. PM2.5 exposure is associated with many adverse health outcomes, including a greater than three-fold increased risk of LRTIs. To date, exposure reduction strategies in wood stove homes have been either inconsistently effective or include factors that limit widespread dissemination and continued compliance in rural and economically disadvantaged populations. In this project, the investigators propose to test the efficacy of two intervention strategies for reducing indoor wood smoke PM2.5 exposures and children's risk of LRTI in three unique and underserved settings: (1) rural mountain valley communities in western Montana; (2) Navajo Nation communities; and (3) Alaska Native Villages. The investigators will conduct a three-arm randomized placebo-controlled post-only intervention trial in wood stove homes with children less than five years old. Education on best-burn practices and training on the use of simple instruments (i.e., stove thermometers and wood moisture meters) will be introduced as one intervention arm (Tx1). This intervention will be evaluated against an indoor air filtration unit arm (Tx2), as well as a placebo arm (Tx3, sham air filters). The primary outcome will be LRTI incidence among children under five years of age. To allow for detection of exposure and outcome differences within each of the three regions, a sample of 324 homes, or 108 within each study area will be equally assigned to each of the three intervention arms. The overall hypothesis is that a low-cost, educational intervention targeting indoor wood smoke PM2.5 exposures will be sustainable, and can reduce children's risk of LRTI in underserved Native and rural communities.
Background: - WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is a rare disease. It can cause cancers, infections, and warts. Researchers want to see if a drug called plerixafor can treat WHIMS. Objective: - To compare plerixafor versus granulocyte colony stimulating factor (G-CSF) for preventing infections in people with WHIMS. Eligibility: - People ages 10-75 with WHIMS who have a CXCR4 gene mutation. Design: - Participants will be screened with a medical history, physical exam, and blood and urine tests. They may have heart and spleen tests and body scans. They may have samples of skin or warts taken. Researchers may take photographs of warts. - Participants will start twice daily self-injections of G-CSF. Their doctors will decide the dosage. - Initial Period (4-12 weeks) - Participants will: - continue the injections and their usual antibiotics and/or immunoglobulin - have blood drawn - keep a daily health diary - Participants will visit the clinic for 2 days without injections. - Adjustment Period 1 (8 weeks): - Participants will: - continue twice daily injections from home - continue the daily health diary - have blood tests every 2 weeks. - Treatment Year 1: - Participants will - receive either plerixafor or G-CSF injections twice daily - continue the health diary - have blood tests every 2 months - visit the clinic about every 4 months - At the end of year 1, participants will visit the clinic for an evaluation. They will switch to the other study drug. They will have an 8-week adjustment and 1-year treatment period. - At the end of year 2, participants will visit the clinic to complete their injections and go back to their previous G-CSF regimen. Participants will continue their daily health diary and have blood tests for 5-6 months.
Despite the use of a standard preoperative skin disinfectant prior to shoulder surgery propionibacterium acne remains a leading cause of post-operative infections. The purpose of this study is to evaluate effectiveness of topical benzoyl peroxide as an adjuvant to chlorhexidine-impregnated skin preparation in attempting to lower the colonization propionibacterium acne prior to surgery. This study will take cultures from patients who are randomly assigned into groups that receive and do not receive benzoyl peroxide as additional skin prep prior to elective shoulder surgery and compare quantified culture results.
