An interventional study of Hemofiltration and Standard acute ischemic stroke treatment in Acute Ischemic Stroke, sponsored by University Medical Center, Kazakhstan. Completed. Open to participants aged 18 Years to 75 Years. Per ClinicalTrials.gov, last updated 2018-03-06.
Sponsored by University Medical Center, Kazakhstan · Not applicable, Interventional, and Treatment
Ischemic stroke is accompanied by a three to four hundred percent increase in the brain's extracellular fluid (ECF) and cerebrospinal fluid (CSF) concentration of glutamate, which diffuses and damages surrounding neurons. In this study we tested our hypothesis that blood glutamate levels can be reduced by hemofiltration, resulting in increased extracellular clearance of glutamate and attenuated neurodegeneration, and that decreased blood glutamate levels can provide significant neuroprotection against stroke-associated neurodegeneration, dysfunction and death. Our primary outcome of interest was to assess safety of hemofiltration in acute ischemic stroke patients.
Ethical Conduct of the Study
Investigator Responsibilities
The principle investigator was responsible for monitoring and responding to adverse events, ethical participant use, compliance with the protocols and any protocol amendments, decisions to end the study early and compliance with data and sample management protocols. CO-PI was trained in both local and international requirements and standards and assisted and report to the PI on these tasks.
Participant Selection and Enrollment
Eligible participants were identified by medical staff at the ICU or emergency department. Enrollment will be standardized and directed by Co-PI.
Screening for Eligibility
A screening log was completed for all eligible patients. Data including inclusion criteria met, exclusion criteria not met and date consent obtained was collected on this form. It was kept in a locked cabinet at the center.
Informed Consent
The informed consent form was available in both Russian and Kazakh languages and was approved by the Institutional Research Ethics Committee (IREC) before use.
Monitoring for safety (hemofiltration-related adverse events (HRAE). All adverse events which occurred during the course of HF including the serious adverse events (SAE) were documented and analyzed. The attending physicians as well as the chief of neurocritical care unit and the principal investigator were responsible for screening for HRAE. In case if any of HRAE occurred all research team members as well as the chief of ICU and the medical director of the hospital were informed. All HRAEs were analyzed by the research team members and the medical director of the hospital. The patients were screened for the following adverse events: hypotension, hypertension, cardiac dysrhythmia, hypothermia or hyperthermia, disorders of water-electrolyte and acid-base balance, bleeding disorders, hemorrhagic transformation of acute ischemic stroke.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
