Filter by:Epstein Barr Virus (EBV) or Cytomegalovirus (CMV) infection results in significant morbidity and mortality in hematopoietic stem cell transplantation (HSCT) patients. HSCT patients often face opportunistic infections due to the immunosuppressive state during transplantation. Antimicrobial drugs are usually used for prophylactic purposes and for treatment after early detectable infections. Unfortunately, some patients develop resistance to such drug treatment. In addition to HSCT patient, immune compromised patient may also be victim to opportunistic infections. Many infections can be effectively managed by functional immune recovery. In this study, the safety and efficacy of microbial-specific cytotoxic T lymphocytes (CTLs) will be investigated.
The purpose of this study is to assess the safety and efficacy of polymyxin B as monotherapy versus a combined polymyxin B-carbapenem therapy against multidrug-resistant (MDR) gram negative infections. The investigators intend to evaluate if this synergistic drug regimen correlates with improved outcomes against gram-negative infections in critically ill patients including: better clinical resolution, reduced length of stay at hospital, reduced length of stay at the intensive care unit, and less recurrence of infection.
Helicobacter pylori is a Gram-negative bacterium with a helical bacillus shape that it's able to penetrate and colonize the stomach mucosal lining by infecting it. The eradication treatment of H. pylori is supported by numerous consensus groups worldwide and it is generally safe and well tolerated. Standard treatment is based on multiple drug regimens. However, its effectiveness has been increasingly compromised due to the emergence of resistant strains, as well as poor adherence to treatment. Therefore, it's proposed a randomized, double-blind, placebo-controlled study whose aims are: 1. Determine whether the combination of two probiotic strains of L reuteri (Gastrus) will improve gastrointestinal symptoms when associated with four-way therapy (of any type). 2. Prove whether supplementation with Gastrus (food supplement) versus Placebo is able to reduce the gastrointestinal adverse effects of quadruple eradication therapy. They will be determined by the GSRS gastrointestinal symptom scale in routine clinical practice.
The purpose of the main study is to describe the incidence of influenza virus and respiratory syncytial virus (RSV) in adults hospitalized with acute respiratory tract infection (ARTI) during the influenza/RSV season, and the purpose of the substudy is to describe the clinical and economic burden in adults hospitalized with confirmed influenza/RSV infection.
Background: Helicobacter pylori infection, which affects over 50% of the global population, is one of the most prevalent infectious diseases in the world. H. pylori infection causes chronic active gastritis and is associated with peptic ulcer, lymphoma of the mucosa-associated lymphoid tissue and gastric cancer. The colonization of H. pylori in the hostile gastric environment is determined by the complex interactions among bacterial, environmental and host factors. Because of the emergence of antibiotic resistance and adverse drug reactions such as diarrhea, the successful rates with standard triple therapy for H. pylori eradication are falling. Vitamin D or its analogues was found to induce autophagy in keratinocytes, macrophages, and various cancer cell types. Our preliminary findings indicated that 1α,25-dihydroxyvitamin D3 could induce cathelicidin expression and autophagy in cultured human gastric epithelial HFE-145 cells and reduced the intracellular survival of H. pylori in a co-culture system. It was also found that cathelicidin alone reduced the survival of drug-resistant strain of H. pylori. 1α,25-dihydroxyvitamin D3 also significantly reduced H. pylori colonization in mice, perhaps through the induction of cathelicidin in the stomach. These findings suggest that vitamin D not only could control H. pylori but also its drug-resistant strains in humans. Emerging evidence suggest that vitamin D might be a cost-effective prophylactic and possibly therapeutic antimicrobial agent for the control and eradication of H. pylori. Since vitamin D acts through mechanisms independent of standard antibiotics, it is expected that vitamin D will be equally efficacious for controlling and eradicating drug-resistant strains of H. pylori. The investigators herein propose that vitamin D in combination of standard antimicrobial therapeutics could improve the eradication rates of drug-resistant H. pylori.
The primary objective of this pilot study is to investigate the safety and tolerability of controlled human urine transfusion in female patients with recurrent UTI's. Seconday and exploratory objectives are to evaluate the diversity of the urine microbiome after urine transfusion, to assess the longevity of changes in the urine microbiome in patients after urine transfusion over a period of 6 months and to assess the frequency of UTI's after the transfusion.
IBIS is a prospective, observational study, which aims to assess the cost of CDI per day, hospitalization and year including description of incremental costs in hospitalized patients, and recurrent episodes, in German hospitals. Exposure to CDI drugs will not be influenced and remains at the discretion of the treating physician. In addition to treatment, Health-related quality of life (HRQL) will be analyzed using standardized questionnaires.
Helicobacter pylori is a bacterium estimated to colonize in the gastrointestinal tract of the half population in the world. Colonization of this bacteria is suspected to be one of the main risk factor for the occurrence of various abnormalities of the upper gastrointestinal tract, such as peptic ulcer and gastrointestinal cancer. The Experts recommend giving triple therapy regimens as first-line eradication therapy for Helicobacter pylori infection. The recommended duration of triple therapy is 10-14 days. However, recent studies suggest triple therapy with longer duration will provide a higher percentage of eradication. This study wanted to show whether 14 days of triple therapy was better than 10 days in Helicobacter pylori eradication.
Alcohol is used to disinfect the skin prior to injections in order to prevent infections caused by bacteria on the skin being injected within tissue. At present, however, clinical trials do not demonstrate a clinical impact of using or not using alcohol swabs on infections and infection symptoms calling into question the practice of using it prior to all injections. These studies are methodologically flawed, and do not specifically examine vaccine injections. The present study is being undertaken to provide some preliminary data for the risk of infection and infection symptoms when alcohol swabs are not used to perform vaccine injections.
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.
