Venezuelan Equine Encephalitis Monovalent Virus-Like Particle Vaccine

EncephalitisEncephalitis18 more

The primary objective of the study is to evaluate the safety and immunogenicity of non-adjuvanted and adjuvanted monovalent VEE VLP Vaccine in healthy adults (ages 18-50 years) when administered via intramuscular (IM) injection at escalating doses of 2 μg, 10 μg, and 20 μg as a 2-dose primary series (Day 0, Day 28) with a Day 140 booster dose. The secondary objective of the study is to evaluate immunogenicity of the vaccine at the aforementioned time points

Brazil ICU Encephalitis Surveillance

EncephalitisCentral Nervous System Infections and Inflammations4 more

Our proposal is to develop a sentinel syndromic surveillance strategy to identify encephalitis cases possibly related to emerging pathogens admitted to ICUs in Brazil. "Sentinel" to allow a diagnostic intensive approach on a smaller number of cases, "syndromic" to guarantee a sensitive criterion to include new or unexpected pathogens, and in ICUs to prioritize potentially severe threats. In a resource-limited setting it won't be possible to monitor and investigate all cases of encephalitis, so a cost-effective algorithm for early identification of the cases that are most likely to be caused by unusual, unexpected or emerging pathogens must be developed. As universal surveillance of encephalitis is not recommended in Brazil, data on incidence, causes and prognosis is not available, leaving a gap in the understanding of the epidemiology of this central nervous system disease in the country. This study will review cases of encephalitis admitted in the last five years to ICUs in a large metropolitan area. Its results will help understand the epidemiology of encephalitis in Brazil and will provide data to build a strategy for early identification of outbreaks and of emerging infectious diseases.

Pharmacokinetics of Understudied Drugs Administered to Children Per Standard of Care

AdenovirusAnesthesia57 more

Understudied drugs will be administered to children per standard of care as prescribed by their treating caregiver and only biological sample collection during the time of drug administration will be involved. A total of approximately 7000 children aged <21 years who are receiving these drugs for standard of care will be enrolled and will be followed for up a maximum of 90 days. The goal of this study is to characterize the pharmacokinetics of understudied drugs for which specific dosing recommendations and safety data are lacking. The prescribing of drugs to children will not be part of this protocol. Taking advantage of procedures done as part of routine medical care (i.e. blood draws) this study will serve as a tool to better understand drug exposure in children receiving these drugs per standard of care. The data collected through this initiative will also provide valuable pharmacokinetic and dosing information of drugs in different pediatric age groups as well as special pediatric populations (i.e. obese).

The Role of Serum Procalcitonin in Diagnosis and Detection of Outcome of Acute Bacterial Meningitis...

CNS Infection in Children

Meningitis is one of the most common central nervous system (CNS) infections encountered in infants and children. The source of infection in meningitis can be bacterial, viral, fungal, or parasitic in origin . Bacterial meningitis is a paediatric emergency with high mortality and morbidity rate. Hence it must be diagnosed and treated promptly. But the similar clinical presentation often makes it difficult to differentiate bacterial and non-bacterial aetiologies in children .

Meningitis Encephalitis: a Metagenomics-Based Etiology & Epidemiology Research

Central Nervous System Infections and Inflammations

Autoimmune encephalitis (AE) is caused by abnormal immune response mediated by autoimmune antibodies of patients, which can be detected by a serial of autoimmune antibodies[4,5,6,7]. At present, the traditional infection diagnosis mainly relies on microbial culture method, which has the characteristics of long cycle, high cost, low detection rate and complex detection process. About 30-60% of encephalitis have unknown etiology[2,3]. On the other hand, the diagnosis and classification of noninfectious encephalitis mainly depend on the detection of autoimmune antibodies, the scope of diagnosis and differential diagnosis is limited, and the relationship between autoimmune encephalitis and infection factors is still unclear. Metagenomics sequencing (mNGS) is a new method that does not rely on microbial culture and can directly detect pathogenic nucleic acids. It has the characteristics of fast, accurate, high throughput, no preference for different pathogen detection, and can detect known and unknown pathogens at the same time. Nowadays, mNGS is widely used in the field of pathogen detection.

Vietnam Cryptococcal Retention in Care Study Version 1.0

MeningitisCryptococcal4 more

It is hypothesized that implementing plasma CrAg screening in clinics providing routine HIV care will enable identification of Vietnamese adult patients with advanced HIV (CD4 ≤100 cells/μL) who have early cryptococcal disease, enable prompt preemptive treatment with high-dose fluconazole, and improve survival.

Development of Risk Score Model and Decision Tree Algorithm for Predicting Infections With CRKp...

Bloodstream InfectionPneumonia6 more

DETERMINE trial is a prospective multicenter multinational cohort study. This study will be carried out to predict the risk of bloodstream infections (BSIs) or other types of invasive infection with carbapenem resistant K.pneumoniae in patients being colonized by CRKp. The results of DETERMINE trial would be quite important to prevent unnecessary coverage of carbapenem resistant Klebsiella pneumoniae in empirical treatment of colonized patients. In this study, both risk score model and decision tree algorithm will be constructed and compared with each other in terms of sensitivity, specificity, positive predictive value and negative predictive value.
