Filter by:The purpose of this study is to determine whether an undirected synovial biopsy technique has the same accuracy in detecting periprosthetic joint infection in the knee as an arthroscopic assisted directed synovial biopsy technique.
Pilot study to evaluate the impact of extremely early ART in the dynamics of viral reservoir, immune activation and inflammation in patients with HIV-1 infection of less than 20 days (Fiebig stages I-II) compared to patients with infection of 20-100 days (Fiebig stages III-V), to induce HIV functional cure.
This is a prospective, randomized study to evaluate the efficacy and safety of switching treatment from Peg-interferon and Ribavirin to direct-acting antiviral agents in Chinese with CHC genotype 1b infection, who are interferon/ribavirin-intolerant.
The H pylori infection remains a public health problem. The eradication rate with the first line triple therapy (PPI-amoxicillin-clarithromycin) is insufficient (estimated at 70%) due to the frequency of resistance to clarithromycin, which reaches 21% in France. Until now,European and French consensus recomended tofavor sequential therapy (5 days PPI-amoxicillin and 5 days PPI-clarithromycin-metronidazole) or quadruple bismuth therapy ( 10 days PPI-tetracyclin,-metronidazole- bismuth). Studies in countries with low prevalence of clarithromycin resistance reported eradication rate of 85% with sequential therapy and reported a low impact of clarithromycin resistance on the effectiveness of this treatment. However, recent studies suggest a greater impact of clarithromycin resistance. Recent meta-analysis shows that empiric sequential therapy is less efficacious than concomitant quadruple therapy. Therefore, recent Maastricht V / Florence meeting October 7-8 2015) recommended to abandon sequential therapy and to favor 14 days concomitant therapy in first line in order to reach an eradication rate >90%. In a multicenter randomized clinical trial (HELICOSTIC 2010-2011 AO ICST 2009), we compared a triple therapy guided by the results of a PCR test that detects resistance to clarithromycin and levofloxacin (HelicoDR ®) to empirical triple therapy (PPI-amoxicillin-clarithromycin). 1384 patients and among them 526 infected patients were enrolled in 10 centers. The results in 415 patients were 73.1% for the empirical treatment versus 85.5% (p <0.001) for the treatment guided by PCR HelicoDR®. This study also demonstrated the limits of the test HelicoDR®: onerous, possibility of contamination, little practical contribution of the determination of resistance to quinolones. Moreover, it has been shown that triple therapy efficiency could be optimized by increasing duration up to 14 days and increasing dose of PPI to 40mg b.d;.and eradications rates > 90% were reported with susceptible to clarithromycin strains. Adverse events are less common with optimized triple therapy than with concomitant quadruple therapy. The main objective is to compare the efficacy of optimized triple therapy guided by the results of a PCR test (eradication rates 90% hypothesized) with quadruple concomitant therapy (eradication rate 90% hypothesized). The secondary objective is to determine side effects of optimized guided triple therapy as well as the quadruple concomitant therapy in France.
The purpose of this clinical trial study is to assess, among young and sexually active women presenting recurrent urinary tract infection (UTIs), efficacy of an optimal dose of cranberry extract quantified and standardized to 37 mg/day of Proanthocyanidins (PACs), compared to a control dose quantified and standardized to 2 mg/day of PACs on mean number of new UTIs during a 6-month follow-up period.
This is a double blind randomized trial in which patients with colorectal cancer undergoing surgery will be selected to receive either a symbiotic formulation or placebo. The researchers will compare incidence of surgical site infection between the study groups.
The primary purpose of this study is to determine if patients randomized to corneal collagen cross-linking plus medical therapy will have a lower prevalence of positive bacterial or fungal cultures immediately after the procedure than patients who received medical therapy alone. The secondary purpose of this study is to determine if patients randomized to corneal collagen cross-linking will have a better visual acuity at 3 and 12 months than patients who receive medical therapy alone.
It is advocated that prolonged infusion of beta-lactamic antibiotics provides better bactericidal effect. The aim of the present study is to randomize patients a to extended cefepime infusion regimen (lasting four hours) or to a usual infusion regimen (not lasting more than thirty minutes) and evaluate the clinical efficacy of this theoretical pharmacokinetic advantage.
The overall goal of the project is to develop and evaluate a home-based intervention to prevent re-infection and transmission of Community-Acquired Methicillin-resistant Staphylococcus aureus (CA-MRSA) in patients presenting to primary care with skin or soft tissue infections (SSTIs). Centers for Disease Control (CDC) CA-MRSA guidelines include incision and drainage, antibiotic sensitivity testing and antibiogram-directed prescribing. Re-infections are common, ranging from 16% to 43%, and present significant challenges to clinicians, patients and their families. Several decolonization and decontamination interventions have been shown to reduce Hospital-Acquired MRSA (HA-MRSA) re-infection and transmission in intensive care units. Few studies examine the feasibility and effectiveness of these infection prevention interventions into primary care settings, and none employ Community Health Workers (CHWs) or "promotoras" to provide home visits for education and interventions about decolonization and decontamination. This comparative effectiveness research/patient centered outcomes research builds upon a highly stakeholder-engaged community-academic research and learning collaborative, including practicing clinicians, patients, clinical and laboratory researchers, and barbers/beauticians. Clinical Directors Network (CDN), an established, NIH-recognized best practice Federally Qualified Health Center (FQHC) Practice-based Research Network (PBRN), and The Rockefeller University propose to address this question through the completion of four aims: (1) To evaluate the comparative effectiveness of a CHW/Promotora-delivered home intervention (Experimental Group) as compared to Usual Care (Control Group) on the primary patient-centered and clinical outcome (SSTI recurrence rates) and secondary patient-centered and clinical outcomes (pain, depression, quality of life, care satisfaction) using a two-arm randomized controlled trial (RCT). (2) To understand the patient-level factors (CA-MRSA infection prevention knowledge, self-efficacy, decision-making autonomy, prevention behaviors/adherence) and environmental-level factors (household surface contamination, household member colonization, transmission to household members) that are associated with differences in SSTI recurrence rates. (3) To understand interactions of the intervention with bacterial genotypic and phenotypic variables on decontamination, decolonization, SSTI recurrence, and household transmission. (4) To explore the evolution of stakeholder engagement and interactions among patients and other community stakeholders with practicing community-based clinicians and academic laboratory and clinical investigators over the duration of the study period.
In this small pilot study, participants (patients and healthy volunteers) will have blood drawn before and after the study intervention (hyperbaric chamber session or normal pressure oxygen breathing. This blood will be analyzed for neutrophil oxidative burst and cytokine analysis.
