  • Title: Temperature management in stroke - an unsolved, but important topic.
    Author: Kallmünzer B, Kollmar R.
    Journal: Cerebrovasc Dis; 2011; 31(6):532-43. PubMed ID: 21487217.
    Abstract:
    Clinical data clearly show that elevated body temperature contributes to an unfavorable outcome after ischemic and hemorrhagic stroke. Two promising therapeutic strategies arise from this observation: (1) treatment of fever aiming to sustain normothermia and (2) induced hypothermia, targeting core body temperatures below 36.5°C. A limited number of studies investigated antipyretic strategies after acute stroke and their results were rather disappointing in terms of clinical efficacy. For that reason, it remains unproven, whether sufficient fever treatment improves functional outcome. On the other hand, strong experimental evidence supports neuroprotective effects of induced hypothermia after stroke. Yet, clinical data on this topic remain preliminary and rely on a limited number of patients, mostly enrolled in nonrandomized trials. Therefore, induced hypothermia may be considered safe and feasible after ischemic stroke, but little can be said regarding efficacy. This review summarizes the data, both on fever treatment and induced hypothermia following stroke, starting with a synopsis of the most important experimental investigations, leading to the latest clinical trials. Given the promising data and the lack of successful acute neuroprotective therapies available thus far, suggestions are given for future investigation on both topics.
