Transient elevation of serum bilirubin (a heme oxygenase-1 metabolite) level in hemorrhagic stroke: bilirubin is a marker of oxidant stress.

Bilirubin (Bil) is the end product of heme catabolism. The production of Bil reflects heme oxygenase-1 expression in response to oxidative stress in various diseases. To assess the role of Bil as a marker of oxidative stress in cases of brain damage, we measured serum Bil concentrations in patients with hemorrhagic stroke. Serum levels of total Bil were measured in 20 subarachnoid hemorrhage patients with symptomatic vasospasms and in 23 patients with intracerebral hemorrhage; concentrations were measured every day for 14 consecutive days. Serum Bil levels were significantly elevated in the early phases in both groups. Moreover, transient elevation was observed on the day prior to the observation of clinical manifestations of symptomatic vasospasm after SAH. Bil, known to be a powerful antioxidant, was induced after hemorrhagic stroke, reflecting the intensity of oxidative stress. Plasma Bil concentrations might serve as a useful marker of oxidative stress in hemorrhagic stroke patients.[1]
