Filter by:Progress in the diagnosis of infectious pathogens depends on the development of effective methods and the discovery of suitable biomarkers. There are several kinds of methods that have been used in diagnosis of various pathogens, such as microscopic examination, culture, serologic diagnosis or molecular approaches, etc. However, these methods have similar limitations, that is, the single detection of reagents. More importantly, physicians seldom consider infections with rare pathogens. Recently developed metagenomic next-generation sequencing (mNGS) has the capability to overcome limitations of traditional diagnostic tests. This new technology could identify all pathogens directly from sample with a single run in a hypothesis-free and culture-independent manner. Studies have shown that mNGS is more sensitive than traditional culture method in clinical conditions such as blood stream, respiratory and general infections. More importantly, due to unbiased sampling, mNGS is theoretically able to identify not only known but also unexpected pathogens or even discovery novel organisms. It should be noted that mNGS also has some limitations such as human genome contamination and possibly environmental microbial contamination. The vast majority of reads in mNGS are derived from human host. This would impede the overall analytical sensitivity of mNGS for pathogen detection. Host depletion methods or targeted sequencing may help to partially mitigate this disadvantage. As mNGS could not, by itself, define whether the detected microbe is the causative pathogen or environmental microorganism, a multidisciplinary discussion by clinicians, microbiologists as well as the lab technicians is required to interpret the result.
The purpose of this study is to survey iron storage levels and their prognostic consequences in the context of acute inflammation. The impact of iron substitution in inflammatory states is controversial. We hypothesize that iron substitution may influence outcome in patients in inflammatory states.
This study will investigate pharmacological interventions between fluconazole and ibuprofen when they are given to premature newborn babys. This in order to find out if the drugs are influencing each other when they are given at the same time. The study is meant to find out if there are reasons to adjust the dose when fluconazole and ibuprofen are given together.
The objective of this study is to conduct a population pharmacokinetic analysis of caspofungin in a population of patients with moderate and severe acute alcoholic hepatitis or liver disease with Child-Pugh score B and C in order to better characterize pharmacokinetic parameters in case of moderate and severe liver dysfunction.
Escalating resistance to antibiotics among disease-causing community bacteria increasingly threatens our ability to treat patients' infections. At the level of the physician-patient encounter, incentives at the patient level often take priority to society; this is often the case with antibiotic prescribing. Each patient level antibiotic treatment decision is based on how we value potential outcomes, including short-term benefits and risks and longer-term risks, including those related to future bacterial resistance to antibiotics. Unfortunately, antibiotics are often prescribed for illnesses unlikely to have a bacterial etiology; even a very small likelihood of benefit seems to outweigh an increased risk of future antibiotic resistance. While short-term effects of antibiotics on colonization with resistant bacteria have been demonstrated, the overall implications of each treatment for future individual, family and societal-level resistance remain difficult to quantify, and are often steeply discounted or ignored during decision-making. Knowledge regarding the longer-term effects of personal and household antibiotic use could better quantify these future resistance-related risks, and help guide antibiotic decision-making for physicians and patients. Infants are born with sterile nasopharyngeal and gastrointestinal tracts and yet, during the 1st year of life, become important reservoirs of resistant organisms; this creates an opportunity to study colonization and resistance starting from a microbiological tabula rasa. In this proposal, we will use an observational cohort to following newborns' antibiotic exposure and longitudinal colonization with specific bacterial pathogens and related antibiotic resistance in the 1st year of life. Our hypothesis is that during the 1st year of life, infants with personal and household antibiotic exposure will have greater colonization with resistan organisms than infants without antibiotic exposure. This project will help us understand the development of bacteria that are resistant to antibiotics within the community, and help to inform judicious decision-making regarding antibiotic prescribing.
The purpose of this study is to investigate the safety and tolerability of AP in sepsis patients with renal failure and to investigate the effect of AP on inflammatory and clinical parameters in sepsis patients with renal failure.
The safety and tolerability of hLF 1-11 has to be established first in HSCT recipients who are at risk of developing, but have not yet developed, infectious complications due to invasive fungal disease. These patients are different from healthy volunteers because they have received myeloablative treatment which not only arrests haematopoiesis resulting in neutropenia but also induces mucosal barrier injury both of which predispose to infections which typically occur during the week after transplant. It is therefore essential to know that hLF 1-11 is when given during neutropenia and mucosal barrier injury before infections ensue
The purpose of this study is to compare the clinical response rate of doripenem versus a comparator in the treatment of hospitalized patients with complicated intra-abdominal infections.
