July 28, 2025 updated by: LI LONGXUAN, Ruijin Hospital

Predictive Role of Early Blood KLK10 and Other Neuroinflammatory Molecules on Clinical Outcomes of Acute Ischemic Stroke

This study aims to investigate the dynamic changes and differential expression characteristics of neuroinflammatory molecules such as kallikrein-related peptidase 10 (KLK10), soluble triggering receptor expressed on myeloid cells 2 (sTREM2), and glial fibrillary acidic protein (GFAP) in the plasma of patients with first-ever anterior circulation acute ischemic stroke (AIS). It will analyze the correlation between these molecules and the severity of neurological deficits, infarct volume, brain edema, hemorrhagic transformation, progressive stroke, and clinical outcomes at three months. The goal is to assess the predictive value of these molecules for AIS prognosis, guiding early treatment and new molecular targets for prevention and treatment.

Detailed Description

  1. Informed Consent and Recruitment: Participants will be recruited based on inclusion and exclusion criteria.
  2. divided two groups: the case group(ischemic stroke group) and the control group(healthy individuals).
  3. First survey(At the time of admission): baseline Assessment- Survey on gender, age, medical history, smoking, drinking habits, and current medication; NIHSS score at admission; measurement of plasma levels of KLK10, sTREM2, and GFAP; a collection of blood glucose, creatinine, high-sensitivity C-reactive protein, blood cell analysis report, and brain MRI or CT imaging reports.
  4. Second survey(24 hours after onset): NIHSS Score and Plasma Levels of KLK10, sTREM2, and GFAP Detection.
  5. Third survey(Within 7 days of onset): Obtain brain CT or MRI reports to extract information on infarct volume, brain edema, and hemorrhagic transformation; perform NIHSS scoring to assess the occurrence of progressive stroke.
  6. Forth survey( 3 months after onset): Final Assessment<if Good Functional Outcome or Mortality>:Record the Modified Rankin Scale (mRS) score at 3 months after stroke.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
the Modified Rankin Scale (mRS) score
Time Frame: Record the Modified Rankin Scale (mRS) score at 3 months after stroke onset
0 No symptoms.1 No significant disability; able to carry out all usual activities, despite some symptoms. 2 Slight disability; able to look after own affairs without assistance, but unable to carry out all previous activities. 3 Moderate disability; requires some help, but able to walk unassisted.4 Moderately severe disability; unable to attend to own bodily needs without assistance, and unable to walk unassisted. 5 Severe disability; requires constant nursing care and attention, bedridden, incontinent. 6 Dead.
Record the Modified Rankin Scale (mRS) score at 3 months after stroke onset

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
the mortality
Time Frame: Record mortality at 3 months after stroke onset
mortality
Record mortality at 3 months after stroke onset
the occurrence of hemorrhagic transformation
Time Frame: Record hemorrhagic transformation within 7 days after stroke onset
based on brain CT scans to evaluate hemorrhagic transformation of cerebral infarction.
