Filter by:Dapsone is a drug that has been used clinically for several decades due to its anti-infective effect, making it widely available. Its neuroprotective effects have been found through its glutamate receptors antagonistic effect. Their main objective was to study the neuroprotective properties in patients with aneurysmal subarachnoid hemorrhage and high-risk factors for the development of cerebral vasospasm. Both the placebo and the dapsone used in this clinical trial were provided by the institution's neurochemistry laboratory.
Despite the efforts made in its treatment, aneurysmal subarachnoid haemorrhage continues to induce high mortality and morbidity rates. Today there are treatment protocols in all hospitals. The vast majority prefer, whenever possible, the endovascular route, given its lesser aggressiveness and morbidity. Although embolization prevents aneurysm' rebleeding, it does remove the subarachnoid blood clot. Therefore, it does not modify the evolution, incidence and severity of vasospasm. The idea is to carry out a 10-year retrospective study classifying patients into five groups based on the type of treatment received, analyzing the results' differences. The aim is to improve what is done as much as possible and to be able to propose potential areas for improvement. Besides, this study will be the basis of a future prospective study, prepared without the current one's biases and errors.
The investigators propose a technique using cone beam CT perfusion (CBCTP) imaging with an acetazolamide challenge as a potential diagnostic tool to detect a defect in cerebral autoregulation at a time when it has not yet caused clinically apparent signs or symptoms. 30 participants will be enrolled at the University of Wisconsin - Madison and can expect to be on study for about 2 weeks.
Soluble epoxide hydrolase (sEH) is the metabolizing enzyme of epoxyeicosatrienoic acids (EETs), which may play a role in reducing neuroinflammation and regulating cerebral blood flow after subarachnoid hemorrhage (SAH). Hypotheses: Pharmacologic inhibition of the sEH enzyme is safe and will result in increased EETs availability in the blood and cerebrospinal fluid. This study is a double-blind, placebo-controlled, phase 1b randomized trial to evaluate the safety and efficacy of GSK2256294, a novel soluble epoxide hydrolase inhibitor in patients with aneurysmal SAH.
