Serum C-reactive protein value on day 14 as a possible prognostic factor of aneurysmal subarachnoid hemorrhage

Le résumé fourni par la source

OBJECTIVE: Serum C-reactive protein (CRP), as a reflection of early brain injury at onset, is a prognostic factor in aneurysmal subarachnoid hemorrhage (aSAH). However, in some severe cases, patients exhibit a good prognosis despite their elevated serum CRP level. Therefore, we examined the relationship between serum CRP transitions in the acute phase of aSAH and the prognosis. METHODS: We recruited 63 patients with aSAH and retrospectively analyzed the relationships between the serum CRP transitions during the acute phase and the prognosis, patient background, and clinical course. RESULTS: Serum CRP values on days 1, 3, and 14 were significantly lower in the good prognosis group than those in the poor prognosis group. Moreover, serum CRP values on days 1 and 14 significantly affected the prognosis in the multiple regression analysis. CONCLUSIONS: A low serum CRP value on day 14, in addition to that on day 1 as reported previously, is associated with a good prognosis of aSAH. Furthermore, a good prognosis of aSAH is determined not only by absence of early brain injury at onset but also by appropriate management to obtain a low serum CRP value on day 14.
