CCM Blood Biomarker Validation Study
Hemorrhagic StrokeIntracerebral1 moreCerebral cavernous malformations (CCMs), one of the most common microvascular malformations in the capillary beds of the brain, are susceptible to hemorrhagic stroke. As an autosomal dominant disorder with incomplete penetrance, the majority of CCM gene mutation carriers are largely asymptomatic but when symptoms occur, the disease has typically reached the stage of focal hemorrhage with irreversible brain damage. Currently, the invasive neurosurgery removal of CCM lesions is the only treatment option, despite the recurrence of the symptoms after surgery. Therefore, there is a grave need for prognostic/monitoring biomarkers as risk predictors for stroke prevention. The objective of the proposal is to develop a set of blood prognostic/monitoring biomarkers as precise risk indicators for stroke prevention. In this project, the plan is to validate the novel serum biomarkers identified in Ccms animal models and human CCMs patients, and utilize these biomarkers with statistical algorithms for risk prediction of hemorrhagic CCMs. This proposal has been formulated based on recent findings of five serum etiological biomarkers associated with disruption of the Blood-Brain Barrier (BBB), the first step for hemorrhagic CCMs in Ccm mice models. This work will lay the groundwork for larger human trials for final validation and revolutionary potential clinical applications.
Oral Propanolol for Surgically Inaccessible Cavernous Malformations
Cavernous Malformations,Cerebral and/or SpinalThe purpose of this study is to evaluate the role of propranolol as an alternative treatment for cavernous malformation in patients that may not be ideal candidates for surgery.
Effect of Oral Propranolol on mRNA Expresssion in Symptomatic Cavernous Malformation
Cerebral Cavernous MalformationsThis is a single center, randomized, trial that will enroll twenty (n=20) patients with a diagnosis of symptomatic cavernous malformations who are planned candidates for surgical resection by one of the investigators, and who meet all of the inclusion and exclusion criteria. Patients will be randomized into two groups: A Treatment group of ten (n=10) patients that will receive oral propranolol at a dose of 60mg per day (one 60mg ER capsule per day) for 7- to 10-days prior to surgery plus their usual medications, and a Control group of 10 (n=10) patients will receive only their routine medications. Currently, the only active treatment alternative for symptomatic cerebral cavernous malformations is surgery. A control group is required to allow for a semi-quantitative comparison with mRNA and miRNA levels in the treatment group.
Treatments and Outcomes of Untreated Cerebral Cavernous Malformations in CHina.
Cerebral Cavernous MalformationsThis nationwide multicenter prospective cohort study will collect the treatment information and outcomes of the patients with previously untreated cavernous malformations (U-CMs) in China (at least 2000 patients from 20 centers). The investigators aim to determine the effect of different treatments on long-term outcomes in patients with untreated cerebral cavernous malformations.
