Active clinical trials for "Encephalitis"

There are no guidelines or studies evaluating duration of anti-epileptic drugs in central nervous system infections. The duration of anti-epileptic drug is extrapolated from traumatic brain injury in which duration of 1 weeks to 3 months is suggested. So the investigators plan to conduct this study to decide the optimal duration of anti-epileptic drug in acute symptomatic seizure in central nervous system infections

Rasmussen encephalitis (RE) is a rare but severe chronic inflammatory brain disease of unknown origin affecting one brain hemisphere. It is usually accompanied by intractable epilepsy. In addition, it often leads to severe disability due to functional deficits caused by atrophy of one brain hemisphere. Hemispherectomy is an effective means of surgical treatment of the epilepsy. It renders the patient, however, hemiplegic, hemianopic and (if the language dominant hemisphere is affected) aphasic. To slow down or even stop the progressive inflammatory damage to the affected brain hemisphere, immunotherapies may be beneficial. According to a literature survey, tacrolimus (twice daily intake of capsules) and intravenous immunoglobulins (monthly infusions) are the most promising compounds for this. In the investigators' study, these two types of treatment are randomly assigned to patients with disease onset within the last year and not too far advanced disability or hemispheric brain injury. The patients are followed to assess prospectively the functional and brain MRI course of the disease.

Background: Morbid obesity is associated with decreased brain µ-opioid receptor availability, possibly resulting in higher food intake needed to gain pleasure from eating. This decrease seems to normalize already 6 months after bariatric surgery, but the longer-term effects have not been studied. Obesity and insulin resistance result in significantly increased brain insulin-stimulated glucose uptake, whereas in every other tissue glucose uptake is lower. One possible explanation to this could be central inflammation and activation of brain glial cells, which has been shown to occur in animal models of obesity. Obesity has also been shown to associate with increased risk of Alzheimer's disease and cognitive decline in several studies. Aims: The first objective of this study is to both study the effects of bariatric surgery as well as compare the effects of gastric bypass and sleeve gastrectomy on food-associated pleasure, extending the follow-up period to 2 years postoperatively. The second aim is to investigate the effect of morbid obesity and weight loss on brain inflammation and gliosis and its association with increased brain insulin-stimulated glucose uptake. Furthermore, association of obesity, insulin resistance, central inflammation and neurocognitive dysfunction are evaluated.

acute viral encephalitis is used to describe restricted CNS involvement (namely, involvement of the brain, sparing the meninges)

The investigators are suggesting that closed suction systems may reduce the risk of the ventilator - associated pneumoniae (VAP) and the contamination of the closest unanimated surfaces. In 2011 David et al. have shown that closed suction systems might reduce the incidence of the late VAP. Research team is thinking that preventive bundle with closed suction systems can prevent to onset of the VAP. All enrolled patients is randomizing into two groups: control group - conventional suctioning and research group - suctioning with closed suction system.

Japanese encephalitis is the single largest cause of viral encephalitis in the world today. It occurs in yearly post monsoon outbreaks in Uttar Pradesh and other parts of India and south east Asia. There is presently no antiviral drug of proven benefit for this illness and treatment is mostly supportive. The drug Ribavirin is already in the market in use for other indications. It has been found useful in West Nile encephalitis and various hemorrhagic fevers caused by related arboviruses. This is a double blind placebo of Ribavirin in Japanese encephalitis. To the best of our knowledge, this is the first such trial in the world. The study hypothesis is that children treated with ribavirin will be no different from those getting placebo in terms of mortality, length of hospital stay, days to return to consciousness and oral feeds, days to become afebrile and convulsion free and in 3 month sequelae rate.

The purpose of this study is to assess: TBE antibody persistence 2 and 3 years after the third TBE vaccination with FSME-IMMUN 0.5ml by means of ELISA and neutralization test (NT). TBE antibody response to a booster vaccination with FSME-IMMUN 0.5ml, by means of ELISA and NT.

Allergic patients especially those undergoing de-sensitization treatment have an altered immune responsiveness. The investigators aim to find out whether this influences immune responses to primary and booster vaccinations.

The risk for tick borne encephalitis increases in Sweden. Together with an increased awareness of the possibility to acquire protection by vaccination, this has led to an increase in the number of doses of the vaccine distributed in Sweden each year - now being approximately 400.000. The first year, two doses with an interval of 1 month is recommended for the general population, followed by a third dose approximately one year later and an additional booster dose three years after the third. Preliminary results from a previous study showed a higher percentage protected (=titer at least 10) after 3 doses than after 2 doses (Rombo et al. EUDRA CT 2011 001348-31, unpublished information). In the same study, there were no differences between those who were vaccinated 0+7+21 compared to 0+30+90. The investigators were surprised to find marked differences between 2 and 3 doses also in the younger control group. The investigators therefore aim to confirm results in a new study and to add a group with a double dose at day 0 and then a single dose at day 30 and 360

The aim of this study is to investigate the immunogenicity response in adults up to 10 years after one booster dose. Data collected from this study will allow for greater information to prescribers who administer TBE vaccine, so that they can appropriately time the administration of booster vaccinations to individuals who received different vaccination schedules and who live in tick borne encephalitis endemic regions.
