Ceftriaxone as Home IV for Staph Infections
Staphylococcal InfectionsOsteomyelitis6 morePatients who are admitted to hospital with serious infections, such as those in bone, joints or spine, require a long course of intravenous (IV) antibiotics. After an initial treatment course in hospital or through a dedicated outpatient antibiotic program many patients can complete their treatment course at home. Such infections are often caused by bacteria called Staphylococci, and currently there are three antibiotic options used routinely. A fourth antibiotic, ceftriaxone, is a promising alternative; it is also effective against Staphylococci, and is more convenient, less costly and easier to give at home, however, it has not been studied thoroughly in a prospective manner. This study will compare ceftriaxone to routinely used antibiotics (cloxacillin, cefazolin or daptomycin) to see if ceftriaxone is equally as safe and efficacious in curing deep-seated Staphylococcal infections in patients receiving home IV antibiotics. Patients with deep-seated infections caused by methicillin-susceptible Staphylococcus aureus (MSSA) or coagulase-negative Staphylococcal species will be randomly assigned home IV treatment with ceftriaxone OR one of the three other antibiotics before leaving the hospital. Patients will then receive usual care from an Infectious Disease physician and Home IV team. The study team will assess whether cure has been achieved by the end of the IV treatment, follow-up at 6 months to see if patients remain infection-free, and record any side-effects of treatment. The overall goal is to determine whether ceftriaxone can be considered non-inferior to usual antibiotic treatment in treating Staphylococcal infections in a home IV setting.
Central Nervous System Infections in Denmark
Central Nervous System InfectionsBacterial Meningitis10 moreThe Danish Study Group of Infections of the Brain is a collaboration between all departments of infectious diseases in Denmark. The investigators aim to monitor epidemiological trends in central nervous system (CNS) infections by a prospective registration of clinical characteristics and outcome of all adult (>17 years of age) patients with community-acquired CNS infections diagnosed and/or treated at departments of infectious diseases in Denmark since 1st of January 2015.
Economic Impact of mNGS on Diagnosis of Post-neurosurgical Central Nervous System Infection
Central Nervous System InfectionsThe aim of the current study was to assess the economic impact of using metagenomic next-generation sequencing (mNGS) versus traditional bacterial culture directed CNSIs diagnosis and therapy in post-neurosurgical patients from Beijing Tiantan Hospital. mNGS is a relatively expensive test item, and whether it has the corresponding health economic significance in the clinical application of diagnosing intracranial infection has not been studied clearly. Therefore, the investigators hope to explore the clinical application value of mNGS detection in central nervous system infection after neurosurgery.
Determination of COVID-19 Related Virus in Central Nervous System
COVID-19 TestingCNS Disease1 moreCoronavirus disease 2019 (COVID-19) is a highly infectious pandemic disease caused by SARS-CoV-2 virus. Central Nervous System (CNS) complications associated with COVID-19 might be secondary sequelae due to exuberant systemic innate-mediated hyper-inflammation, which may impair neurovascular endothelial function, disrupt blood brain barrier (BBB), activates CNS innate immune signaling pathways, and induces parainfectious autoimmunity, potentially contributing to the CNS manifestations. Although the predominant clinical manifestation of SARS-CoV-2 is characterized by dyspnea, unremitting fever and hypoxemic respiratory failure, neurologic manifestations do occur in most hospitalized SARS-CoV-2 patients and include non-specific encephalopathy, psychosis, meningitis/encephalitis, myelitis, cerebrovascular events, Guillain-Barre' syndrome, and cranial or peripheral neuropathies, such as anosmia and ageusia. To date, data about primary CNS involvement due to neurotropism and direct neuroinvasion are still lacking.
National Study on Listeriosis and Listeria
ListeriosisPregnancy Complications4 moreListeriosis is a foodborne infection responsible for severe disease. Three main forms are described: septicaemia, central nervous system infections and maternal-fetal infections. Available data on the disease, are mostly retrospective and do not provide an accurate picture of the clinical / biological / genetic risk factors for the disease, nor identify any element to determine which patients are at higher risk of death, severe neurological impairment or fetal loss. The primary purpose of the study is to identify clinical, biological and genetic risk factors for systemic listeriosis and the determinants of listeriosis-associated mortality in the setting of a large prospective nation-wide study.
Central Nervous System Disorders Following Hematopoietic Stem Cell Transplantation
Central Nervous System InfectionsCentral Nervous System Complication4 moreAll patients undergoing allogeneic or autologous HSCT at the participating centres will be observed. Once a diagnosis of CNS disorder is made, additional data will be reported for these patients. We will identify clinical and diagnostic characteristics such as cerebrospinal fluid (CSF) and neuroimaging patterns, risk factors, response to treatment (including novel antifungal agents such as isavuconazole) and outcome. In addition, risk factors for CNS disorders after allogeneic and autologous HSCT will be analyzed using a prospectively assessed matched control group. In the future, this study might be the basis for an interventional trial (e.g. using a prophylactic approach).
Establishment of Prevention and Control System of Central Nervous System Infection
Central Nervous System (CNS) InfectionEncephalitis1 moreCentral nervous system (CNS) infection is a common nervous system acute and severe disease, mainly manifested as encephalitis, meningitis and meningoencephalitis, but also manifested as brain abscess and brain granuloma et al. The basis for the diagnosis of CNS infection lies in the detection of pathogens from brain parenchyma or cerebellar spinal fluid (CSF). However, CSF is relatively difficult to obtain and the sample size is small, which limits the rapid and definite diagnosis of CNS infection pathogens. In addition, CNS infection usually has non-specific clinical manifestations, so it is difficult to identify the pathogen for about half of CNS infection. Metagenomic next generation sequencing (mNGS) and biochip technology provide new means to identify the pathogens of CNS infection. This study analyzes the incidence and epidemic characteristics of CNS infection in China, to standardize the CSF sample processing process, shorten the detection time, increase the sensitivity and specificity of pathogen detection, reduce the detection cost, identify the common pathogens of CNS infection, and establish a standardized rapid diagnosis system, effective prevention and control system.
Protecting Brains and Saving Futures - the PBSF Protocol
Brain InjuriesCongenital Heart Disease15 moreBackground: Multiple neonatal disorders are associated with risks of neurological injury. Thus, management of these infants should involve a coordinated approach to permit early diagnosis with improved clinical care. Such initiative involves the use of standardized protocols, continuous and specialized brain monitoring with electroencephalography (EEG), amplitude integrated EEG (aEEG) and Near Infrared Spectroscopy (NIRS), neuroimaging and training. Brazil is a very large country with disparities in health care assessment; some neonatal intensive care units (NICUs) are not well structured and trained to provide adequate neurocritical care. However, the development and implementation of these neurocritical care units requires high expertise and significant investment of time, manpower and equipment. In order to reduce the existing gap, a unique advanced telemedicine model of neurocritical care called Protecting Brains and Saving Futures (PBSF) protocol was developed and implemented in some Brazilian NICUs. Methods: A prospective observational cohort study will be conducted in 20 Brazilian NICUs that have adopted the PBSF protocol. All infants receiving the protocol during January 2021 to December 2023 will be eligible. Ethical approval will be obtained from the participating institutions. The primary objective is to describe the use of the PBSF protocol and clinical outcomes, by center and over a 3 years period. The use of the PBSF protocol will be measured by quantification of neuromonitoring, neuroimaging exams and sub-specialties consultation. Clinical outcomes of interest after the protocol implementation are length of hospital stay, detection of EEG seizures during hospitalization, use of anticonvulsants, inotropes, and fluid resuscitation, death before hospital discharge, and referral of patients to high-risk infant follow-up. These data will be also compared between infants with primarily neurologic and primarily clinical diagnosis. Discussion: The implementation of the PBSF protocol may provide adequate remote neurocritical care in high-risk infants with optimization of clinical management and improved outcomes. Data from this large, prospective, multicenter study are essential to determine whether neonatal neurocritical units can improve outcomes. Finally, it may offer the necessary framework for larger scale implementation and help in the development of studies of remote neuromonitoring.
