ClinConnect Summary

This study is looking at people who have a condition called immune thrombocytopenia (ITP), which is a disorder where the body’s immune system mistakenly attacks platelets—tiny blood cells that help with clotting. Because of this, people with ITP can have bleeding problems but may also have a higher risk of having a type of stroke called an acute ischemic stroke, which happens when blood flow to the brain is blocked. This research aims to better understand how often these strokes happen in people with ITP, how they are treated, what their health outcomes are, and the related healthcare costs. By collecting detailed information over time, the study hopes to improve care and quality of life for patients with both conditions.

People who might join this study are those who were diagnosed with ITP and later had an acute ischemic stroke, and who have been treated at Peking University People's Hospital since 2005. Participants will provide information through questionnaires, phone or video calls, online platforms, and in-person visits. The researchers will also review medical records to track treatments, other health issues, outcomes, and costs. This study is not yet recruiting, and it includes patients of all ages and genders who can provide follow-up information. Those with severe mental health issues or other reasons that make follow-up difficult may not be eligible. Overall, this study seeks to gather important information that could help doctors better diagnose and treat this challenging combination of conditions.
