Uitkomstmaten
Primaire uitkomstmaten
Primary outcome is perihematomal oedema on MRI at day 7±1, which will be correlated with perihematomal uptake of 18F-DPA-714 on PET imaging at day 3±1 as a measure of neuroinflammation.
Achtergrond van het onderzoek
Spontaneous intracerebral haemorrhage yearly affects over 6000 patients in the Netherlands. It is the deadliest stroke subtype, with a 30-day case-fatality of 40%. Of patients surviving, only few gain independence. However, effective treatment options are still lacking. This is reflected in het prognosis which has not improved over the last 30 years. Inflammation is known to play a vital role in the development of secondary brain injury related to intracranial haemorrhage. The release of blood products in the brain parenchyma leads to an activation of the immune system. This subsequently leads to destruction of the blood brain barrier and the formation of perihematomal oedema. In vivo studies linking serum inflammatory markers, blood brain barrier disruption and perihematomal oedema with perihematomal inflammation are lacking.
The CHIPS study strives to assess this relation in patients with acute, spontaneous intracerebral haemorrhage through blood sampling and MRI and PET-CT imaging. This will provide essential insights for the development of new treatment procedures to ameliorate secondary brain injury in intracranial haemorrhage.
This study has a prospective, observational cohort study design.
Doel van het onderzoek
We hypothesize that serum inflammatory markers, BBB integrity and PHO are associated with perihematomal inflammation.
Onderzoeksopzet
Patients will undergo blood sample collection at day 0, 1, 3 and 7.
At day 3±1, patients will undergo a 18f-dpa-714 PET-CT scan.
At day 7±1, patients will undergo a (DCE)-MRI-scan
