Abstract | PURPOSE: METHODS: ISOCRATE was a single-center randomized controlled trial comparing rewarming at 0.50 °C/h versus 0.25 °C/h in patients coma after shockable OHCA in 2016-2020. The primary outcome was serum IL6 level 24-48 h after reaching 33 °C. Secondary outcomes included the day-90 Cerebral Performance Category ( CPC) and the 48-h serum neurofilament light-chain (NF-L) level. RESULTS: We randomized 50 patients. The median IL6 area-under-the-curve was similar between the two groups (12,389 [7256-37,200] vs. 8859 [6825-18,088] pg/mL h; P = 0.55). No significant difference was noted in proportions of patients with favorable day-90 CPC scores (13/25 patients at 0.25 °C/h (52.0%; 95% CI 31.3-72.2%) and 13/25 patients at 0.50 °C/h (52.0%; 95% CI 31.3-72.2%; P = 0.99)). Median NF-L levels were not significantly different between the 0.25 °C/h and 0.50 °C/h groups (76.0 pg mL, [25.5-3074.0] vs. 192 pg mL, [33.6-4199.0]; P = 0.43; respectively). CONCLUSION: In our RCT, rewarming from 33 °C at 0.25 °C/h, compared to 0.50 °C/h, did not decrease the serum IL6 level after shockable CA. Further RCTs are needed to better define the optimal TTM strategy for patients with CA. Trial registration ClinicalTrials.gov, NCT02555254 . Registered September 14, 2015. TAKE-HOME MESSAGE:
