Glyoxal in hyperglycaemic ischemic stroke - a cohort study.

Background: Hyperglycaemia is frequent in acute ischemic stroke and denotes a bad prognosis, even in the absence of pre-existing diabetes. However, in clinical trials treatment of elevated glucose levels with insulin did not improve stroke outcome, suggesting that collateral effects rather than hyperglycaemia itself aggravate ischemic brain damage. As reactive glucose metabolites, glyoxal and methylglyoxal are candidates for mediating the deleterious effects of hyperglycaemia in acute stroke.

Antibodies against neural antigens in patients with acute stroke: joint results of three independent cohort studies.

Background And Purpose: Ischemic stroke (IS) and hemorrhagic stroke (HemS) typically lead to a breakdown of the blood-brain barrier with neural antigen presentation. This presentation could potentially generate destructive auto-immune responses. Pre-existing antineuronal and antiglial antibodies (AA), predominantly NMDA receptor antibodies, have been reported in patients with stroke.
