ISRCTN ISRCTN98608690
ClinicalTrials.gov identifier
Public title The effect of paracetamol (acetaminophen) and ibuprofen on body temperature in acute stroke: a phase II double-blind randomised placebo-controlled trial
Scientific title
Acronym PISA
Serial number at source N/A
Study hypothesis To study the effect of high-dose ibuprofen and to confirm the previously observed reducing effect of high-dose paracetamol on body temperature, and to study their safety in normothermic and subfebrile patients with acute ischaemic stroke.
Ethics approval The medical ethics committees of the three hospitals have approved this protocol.
Study design Randomised controlled trial
Countries of recruitment The Netherlands
Disease/condition/study domain Stroke
Participants - inclusion criteria 1. An acute ischaemic anterior circulation stroke
2. A body temperature greater than 36.0°C or less than 39.0°C
3. A CT scan that is compatible with acute ischaemic stroke
4. A focal deficit without rapid improvement
5. A possibility to start treatment within 24 hours after stroke onset
Participants - exclusion criteria 1. Severe aphasia, defined as an aphasia score of 2 or 3 on the National Institutes of Health Stroke Scale (NIHSS)
2. Treatment with an non-Steroidal Anti-Inflammatory Drug (NSAID) deemed necessary

8. Colitis ulcerosa
9. Pregnancy
10. Use of corticosteroids
11. A severe concomitant medical condition that could affect the assessment of the effect of the study medication on temperature
12. Residual neurological impairment resulting from a previous stroke that may hamper the assessment of functional outcome
13. Death appearing imminent
14. No informed consent given
Anticipated start date 01/12/2000
Anticipated end date 31/12/2001
Status of trial Completed
Patient information material
Target number of participants 75
Interventions 1. Paracetamol 6 g daily, for 5 days
2. Ibuprofen 2.4 g daily, for 5 days
3. Placebo for 5 days
Primary outcome measure(s) Body temperature at 24 hours from start of treatment.
Secondary outcome measure(s) 1. Change in baseline temperature at 1 and 5 days from start of treatment
2. Time with elevated body temperature (greater than 37.0°C) (area under the curve) during the first 24 hours and the first five days

Tertiary outcomes:
Functional outcome at one month, as determined by the scores on the modified Rankin Scale (mRS) and Barthel Index (BI).
