Active clinical trials for "Communicable Diseases"

The purpose of this study is to determine the feasibility of identifying novel etiologic agents associated with SARI in patients who have required intubation and in whom, after analysis, a causative agent was not identified by standard microbiologic (culture) and multiplex real-time Polymerase Chain Reaction (PCR) platforms. Taking into account that isolation of any pathogens is generally time sensitive, the study will evaluate subjects that are culture negative at the time of consent. Not all subjects will actually prove to be culture negative. Additionally, the study will compare etiologic agents identified on broncho-alveolar lavage (BAL) to etiologic agents identified by routine upper airway testing on all subjects with SARI.

This open-label, prospective, multi-center, non-interventional, observational, parallel cohort study intended to provide real life data on the treatment duration, effectiveness and safety of tedizolid and linezolid when treating ABSSSI hospitalized patients in a real practice setting.

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.

This study will be conducted to assess the efficacy of caries excavation using the papain-based chemo-mechanical method (Brix 3000) in comparison to conventional rotary tools in the reduction of the bacterial population in occlusal carious cavities

Infection after total joint arthroplasty can have devastating consequences. Adhesive drapes have been traditionally used at our institution to help reduce the risk of wound contamination and infection by superficial skin flora. Our primary objective is to determine if a cyanoacrylate-based sealant (FloraSeal microbial sealant) is superior to conventional iodine impregnated drapes in prevention of both superficial and deep surgical site infections in total joint arthroplasty (TJA) patients. A prospective, randomized controlled model will be used to answer this question.

New generations of fluoroquinolones, like levofloxacin and moxifloxacin, exhibit a broad-spectrum activity against Gram-positive and Gram-negative bacteria, and have been successfully introduced into the treatment of Helicobacter pylori infection. However, it was suggested that resistance to fluoroquinolones has been increasing in the Korean population and the resistance is most likely mediated through point mutation in gyrA. Gemifloxacin (FACTIVE®) is an enhanced-affinity, broad-spectrum fluoroquinolone suitable for once-daily, oral dosing. In vitro studies have shown that gemifloxacin displays potent activity against Gram-positive organisms, whilst retaining good activity against Gram-negative organisms. Gemifloxacin is the most potent member of the quinolone class against S. pneumoniae with activities 16-64 times greater than those of ciprofloxacin and ofloxacin and 2-8 times greater than those of moxifloxacin. Importantly, gemifloxacin displays potent in vitro activity against strains of S. pneumoniae with known resistance to β-lactams, macrolides and other members of the quinolone class. This potent activity is believed to be due to the enhanced affinity of gemifloxacin for topoisomerase IV, the major fluoroquinolone target in S. pneumoniae. Furthermore, gemifloxacin displays potent activity against H. influenzae and M. catarrhalis and atypical organisms such as L. pneumophila, C. pneumoniae and M. pneumoniae. It has proven particularly effective in respiratory and urinary tract infection.

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.

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: 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). 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 objective of this study is to evaluate the efficacy and safety of accelerated cross-linking (Avedro Inc., Waltham, USA) in the management of microbial keratitis as adjunctive therapy.

The purpose of this study is to assess efficacy of 14-day antimicrobial susceptibility test guided quadruple therapy for the rescue treatment of Helicobacter pylori infection, then comparing it with 14-day personal medication history guided therapy to tell which one has a better performance in both efficacy and safety.
