Filter by:Study for performance evaluation of the QIAstat-Dx® Meningitis/Encephalitis Panel in comparison with other chosen comparator methods.
The purpose of this study is to assess the safety, tolerability, and immunogenicity of the combined meningococcal groups A, B, C, W and Y (MenABCWY) vaccine (GSK3536819A) intended to protect against invasive meningococcal disease (IMD) caused by all 5 meningococcal serogroups.
Meningitis is the development of an inflammatory reaction in the meningeal space, most often of infectious origin. Many pathogens can cause meningitis, the severity of which varies greatly. Patients presenting with a febrile meningeal syndrome are most often managed in the emergency room, where the challenge for physicians is to quickly differentiate bacterial and viral meningitis. Viral meningitis is the most common, with enterovirus meningitis having a classically excellent prognosis. Bacterial meningitis is less frequent but more serious.The current public health objective is to save antibiotics. Investigator hypothesizes that the BMS score can be used to exclude bacterial meningitis in the emergency department in an adult European population of patients with suspected bacterial meningitis.
Encephalitis and meningitis are serious central nervous system diseases. There is currently a lack of comprehensive and accurate diagnosis and treatment pathways. Therefore, we conducted this multicenter, prospective, and randomized controlled study. It was designed to evaluate the diagnostic performance and its impact on the outcomes of the patients enrolled. As such, we came to the results of the optimal process of diagnosis and treatment strategy of encephalitis/meningeal syndromes with improved effective treatments.
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 .
Intracranial infection is one of the common clinical complications after neurosurgery, especially after external cerebrospinal fluid drainage. Postoperative intracranial infection has a very high incidence, and its incidence is about 0.34%-3.1%. Once infection occurs, it will directly affect the length of hospitalization, mortality and disability of postoperative patients. The pathogenic bacteria of postoperative intracranial infections include G-bacteria and G+ bacteria, and fungi. Common G+ bacteria are Staphylococcus aureus. Common G-bacteria are Acinetobacter baumannii, Klebsiella pneumoniae, and Pseudomonas aeruginosa Bacteria, Escherichia coli and so on. In recent years, studies have reported that postoperative intracranial infections of G-bacteria are gradually increasing. In the previous study of our research group, it was found that Acinetobacter baumannii and Klebsiella pneumoniae accounted for the top two pathogens of postoperative intracranial infections in ICU. In particular, the proportion of carbapenem-resistant G-bacteria has increased, which brings difficulty and challenge to the treatment and seriously affects the prognosis of patients. Different pathogen infections may lead to different prognosis of patients with intracranial infection after neurosurgery. With different pathogens as the starting point, there are few studies comparing the clinical features, risk factors, and prognosis of intracranial infections after neurosurgery. Therefore, it is great significant to explore and understand different pathogenic bacteria, risk factors, drug resistance, treatment options, and prognosis after neurosurgery.
This study seeks to identify and test host RNA expression profiles as markers for infections in young infants. Preliminary studies have shown high sensitivity and specificity for the discrimination of bacterial from non-bacterial infections in children, but the method has only been investigated in a limited number of young infants. The study aims to include 65 young infants with serious bacterial infections. The samples will be analysed by RNA sequencing. New diagnostic tools may help reduce unnecessary antibiotic treatment, antibiotic resistance, side-effects, hospitalisation and invasive procedures.
Visibly traumatic as well as microtraumatic lumbar punctures (LP) are very common in the neonatal period. The presence of blood makes it difficult to interpret cerebro-spinal fluid (CSF) findings. Clinicians often perform a repeat LP in the hope that some of the red blood cells would have cleared by then, allowing a better interpretation of the CSF findings. There is no published information whether a repeat LP provides any added information to the original traumatic LP, and if so what is the best time to repeat an LP after a traumatic LP. In this randomised controlled trial (RCT), we plan to randomly allocate neonates following a visibly traumatic LP to either undergo a repeat LP at 24 hours or 48 hours later to determine which LP gives more accurate results.
The investigator's purpose is to study the population pharmacokinetics of commonly used antimicrobial agents in children of bacterial meningitis with augmented renal clearance and assess dosage individualization feasibility.
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.
