Exploring how the human microbiome can predict outcomes in acute ischemic stroke patients

Dynamic Changes in Human Microbiome Predict the Risk of Adverse Outcomes in Patients With Acute Ischemic Stroke: a Multicenter Prospective Cohort Study

Observational Zhujiang Hospital · NCT06240468

This study is trying to see if the bacteria in our bodies can help predict how well people with acute ischemic stroke will recover and if they might face any emotional or thinking problems afterward.

What this trial studies

This multicenter, prospective cohort study aims to investigate the predictive value of the human microbiome and its metabolites for adverse outcomes in patients with acute ischemic stroke (AIS). A total of 2000 AIS patients will be enrolled, with neurological function scores evaluated during and after hospitalization. Biological samples, including blood, urine, feces, and periodontal swabs, will be collected at multiple time points to analyze changes in the microbiome and their correlation with stroke prognosis. The study also seeks to identify markers related to cognitive and emotional complications following stroke.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-80 who have been diagnosed with acute ischemic stroke or transient ischemic attack within 7 days of onset.

Not a fit: Patients with recurrent strokes within the past year or significant pre-existing health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new predictive tools for assessing the risk of adverse outcomes in stroke patients based on their microbiome.

How similar studies have performed: While the relationship between the microbiome and various health outcomes is being explored, this specific approach in acute ischemic stroke is relatively novel and has not been extensively tested.
