Brief Summary
Subarachnoid hemorrhage (SAH) consists of blood extravasation into the space between arachnoid and pia mater. Bleeding is a consequence of cerebral aneurysm rupture in most cases. Despite incidence being only 9 cases out of 1000 people per year, young age and high mortality and morbidity lead to loosing several years of healthy life. Therapy priorities are: preventing rebleeding, with endovascular treatment (when possible) or neurosurgical aneurism clipping; preventing complications associated with blood extravasation into subarachnoid pace, such as acute hydrocephalus treatment (that occurs in 20% of patients), by ventricular external drainage positioning, and delayed cerebral ischemia, mainly due to vasospasm, by endovenous administration of nimodipine; optimal perfusion pressure maintenance. Endogenous osteopontin (OPN) is thought to fulfill a protective activity over ischemic damage both in brain and other organs, including kidney. Besides, recombinant OPN administration markedly decreases ischemic area in a focal cerebral ischemia model, by an antiapoptotic action. Recent in vivo studies on animal models of SAH demonstrated that OPN plays a major role: treatment with OPN seems to prevent vasospasm reducing smooth muscle cells and endothelial cells apoptosis. Microparticles are mediators released by platelets, leucocytes, erythrocyte and endothelial cells. In ischemic stroke endothelial microparticles levels directly relate to clinical severity and ischemic area extension. In typical parenchymal haemorrhage microparticles levels are higher both in blood and in liquor and associated with worse clinical outcome. In SAH increased microparticle levels have been demonstrated, especially in the days of the bleeding, and microparticle levels change based on subtypes. Data disagree about the subtypes involved and their time course. This study aims to evaluate the correlation between OPN and microparticles levels and vasospasm development/ischemic lesion at the CT-scan, and subsequently with medium and long-term patients outcome.

Outcome Measures
Primary Outcomes (1)
Correlation between OPN and microparticle levels and vasospasm development/ischemic lesion at the CT-scan, and subsequently with medium and long-term patients outcome.
The levels of OPN and microparticles will be related to: 1. the presence or absence of vasospasm development 2. the presence or absence of ischemic lesion at the CT-scan 3. 3-6 months outcome evaluated with the GOS-E
Day 7 is the day expected for cerebral vasospasm. Therefore for the correlation between OPN/microparticles and vasospasm/ischemic lesion at CT scan will be evaluated on day 7.
Secondary Outcomes (1)
In vitro stimulation of renal and pulmonary endothelial cells with microparticles
Microparticles isolated from patient blood on the day of the expected maximum release, i.e., day 7 will be incubated in vitro with renal and pulmonary endothelial cells.
Other Outcomes (1)
Levels of OPN in liquor and blood of patients with SAH
Time course of OPN levels measured the day of bleeding and on days 1, 2, 3, 5, 7, 9, 11.
Interventions
Data on the type of patients enrolled have been described already in other sections.
Eligibility Criteria
Patients with subarachnoid haemorrhage admitted to Neurosurgery or ICU of Ospedale Maggiore della Carita will be considered eligible, when meeting including criteria, within 24h from bleeding.
You may qualify if:
- Age between 18 and 80 years
- Subarachnoid haemorrhage from cerebral aneurysm rupture
- Indication to external liquor drainage
You may not qualify if:
- Age less than 18 or more than 80 years
- Bleeding occurred more than 24 hours before admission
- Known coagulopathies or antiplatelet or vitamin K antagonist treatment
