Active clinical trials for "Encephalitis"

Background: Most people who get COVID-19 seem to recover with no long-term effects. However, some people who recover from acute COVID-19 infections report lingering symptoms. This is called long COVID. Many people with long COVID report symptoms related to the nervous system; these can include problems with fatigue, speech, and memory. Objective: To test motor memory in people with long COVID, compared to healthy volunteers. Eligibility: People aged 18 to 90 years who are also enrolled in study protocol 000089. Healthy adults are also needed. Design: Participants will be screened by telephone. They will confirm they are able to type without discomfort using their nondominant hand. They will confirm they have access to a computer connected to the internet. All study tasks will be done online. Participants will complete 2 tasks in 2 days. Participants will be sent a link to a website. The website will give them instructions. They will place the fingers of their nondominant hand over 4 numbers on the keyboard and type a sequence (eg, 4-1-3-2-4). They will type this sequence as often as they can in 10 seconds. Then they will rest for 10 seconds before repeating the task. They will repeat this pattern for 15 minutes. After they finish the typing task, participants will take a 10-minute questionnaire. They will answer questions about their experiences with COVID-19 and memory issues; they will say which hand they use for tasks such as brushing their teeth or throwing a ball. Participants will get a notice to repeat the typing task 22 hours after they finish the first one. They should complete the second task within 28 hours....

Oropharynx is the main source of pathogen microorganisms for the ventilator - associated pneumoniae. As known bacteriophages can eliminate different pathogen microorganisms or reduce a degree of a pathogen's colonization. The research team is considering that oropharyngeal decontamination with bacteriophages can prevent the developing of the ventilator - associated pneumoniae. There will be three groups in this investigation: placebo, antiseptic drug (Octenisept) and bacteriophage (Sexthaphag).

This study evaluates the immunogenicity and safety of a purified inactivated JE vaccine compared to a commercialized JE vaccine. In this phase III, randomized, blind trial, infants at 6-23 months of age were randomly assigned to three groups to receive experimental vaccine or control vaccine with two different vaccination schedule respectively.

The Swiss-Ped-IBrainD is a national patient registry that collects information on diagnosis, symptoms, treatment, and follow-up of pediatric patients with an inflammatory brain disease in Switzerland. It was first implemented in 2020 in the pediatric clinic of the university hospital in Bern. Further centers all over Switzerland were opened for recruitment in 2021; Aarau, Basel, Bellinzona, Chur, Geneva, Lausanne, Lucerne, St. Gallen, and Zurich. The center in Winterthur is expected to be open for recruitment by autumn 2021. The registry provides data for national and international monitoring and research. It supports research on inflammatory brain diseases in Switzerland and the exchange of knowledge between clinicians, researchers, and therapists. The registry aims to improve the treatment of children with inflammatory brain diseases and optimizing their health care and quality of life.

Determination of autoantibodies against fragments derived from neurons, glia, and myelin sheath is instrumental in aiding diagnosis, differential diagnosis, as well as determining disease status of neuromyelitis optica spectrum disorders (NMOSD), myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD), autoimmune encephalitis (AE). Cell based assay (CBA) has been frequently recommended to detect autoantibodies of neuroantigens in the aforementioned neurological disorders. However, antibodies with low abundance or low affinity often fall beyond the threshold of CBA and pose significant challenges in practice. To this end, the investigators adopted a tyramide signal amplification (TSA) technology with the basis of CBA to improve sensitivity. The preliminary results suggest that this TSA-CBA platform is superior to conventional CBA in registered signals of the titer autoantibodies. In elevating the sensitivity, TSA-CBA also preserves antigen confirmation. This prospective study is launched to compare the sensitivity, specificity, clinical correlation between CBA and CBA-TSA, in determining autoantibodies against aquaporin 4 (AQP4-IgG), myelin oligodendrocyte glycoprotein (MOG-IgG), N-methyl-D-aspartate receptor (NMDAR-IgG) in a multicenter, double-blind setting.

The number of acute encephalitides diagnosed each year is gradually increasing, reaching approximately 5 to 10/100,000 per year; more than 50% of etiologies currently remain unknown. The majority of them are acute encephalitis of infectious origin, but it is estimated that 20% of encephalitis in northern Europe is related to an autoimmune mechanism with the majority of encephalitis with anti-NMDA Ac discovered recently in 2007. The study of a large American encephalitis cohort showed a death rate of 3% to 7% in cases of autoimmune encephalitis. Furthermore, delay in the initiation of effective treatment (tumor removal or immunotherapy) beyond 4 weeks is associated with a poor prognosis at 1 year. It is therefore necessary to better understand the signs of autoimmune encephalitis in order to recognize the disease quickly and to start a treatment quickly; in order to improve the management and the prognosis of these children.

Carotid artery stenosis is observed in about 3% of ≥ 60 years subjects and accounts for around 10-20% of all ischemic strokes. Beyond the degree of stenosis, plaque composition affects the risk of ischemic stroke. Identification of patients with vulnerable plaques at higher risk of stroke who might benefit from carotid revascularization is crucial. A growing body of evidence suggests that the lectin pathway of the complement system, and especially the ficolin-2, is involved in atherosclerosis. It has been hypothesized that circulating levels of ficolin-2 increase during chronic inflammatory conditions (i.e. growing atherosclerotic plaque) whereas they fall during sub-acute or acute inflammatory conditions (i.e. plaque rupture and acute ischemic stroke) because of consumption (binding to targets). Therefore, ficolin-2 has been proposed as a biomarker informing on the specific state of the plaque. However, in acute ischemic stroke due to carotid stenosis, both plaque rupture and stroke injury contribute to lectin pathway activation, thus affecting circulating levels of ficolin-2. Until now, the relative contribution of plaque and brain inflammation on circulating levels of ficolin-2 has not been documented. In the present study the investigators aim to assess the association between circulating levels of ficolin-2 and carotid and brain inflammation on [18F]DPA-714 positron emission tomography (PET)/MRI in patients with transient ischemic attack or acute ischemic stroke due to carotid stenosis. For that purpose, the investigators intend to include 30 patients with transient ischemic attack or acute ischemic stroke due to ≥ 50%. carotid stenosis. Each patient will have a measure of plasmatic level of ficolin-2 as well a [18F]DPA-714 PET/MRI to quantify the fixation of the radiotracer on carotid and brain.

Since the initial study of cases reported between 2009 and 2015, adalimumab has become in France the immunomodulatory reference treatment used after failure of corticosteroids and immunoglobulins before a possible recourse to the hemispherotomy. This observational study is intended to document the long-term efficacy and safety of Adalimumab therapy in patients with Rasmussen encephalitis.

COLETTE is an interventional study for which blood, cerebrospinal fluid and post-mortem tissues are collected in patients with status epilepticus or epilepsy associated to dysimmune encephalitis as well as in control patients, to better understand the pathophysiology of these severe epileptic disorders.

The purpose of this European, multicentric, prospective, non-interventional study is to document and evaluate the efficacy and safety of the treatment of severely infected patients with intravenously administered fosfomycin, including patients with osteomyelitis, complicated urinary tract infection, nosocomial lower respiratory tract infection, bacterial meningitis/central nervous system infection, bacteraemia/sepsis, skin and soft tissue infection, endocarditis or other infections, each as far as covered by the respective nationally relevant SmPC.
