Objective: Aim of this study was to investigate in patients with aneurysmal subarachnoid hemorrhage (SAH) and external ventricular drain (EVD) whether interleukin-6 concentrations in the cerebrospinal fluid (IL-6_CSF) could be useful to early identify patients at risk for cerebral vasospasm (=cVSSAH) or EVD-associated ventriculitis (=VCSAH).

Methods: IL-6_CSF levels were collected daily in 63 consecutive patients with SAH and EVD for 17 consecutive days after SAH. VCSAH was diagnosed 17 times, cVSSAH 27 times and 19 patients had an uneventful course without additional complication after SAH (=SAH-).

Results: Whereas highest IL-6_CSF levels were measured on the 2nd day in uneventful SAH-, cVSSAH and VCSAH were associated with peak values on the 8th day (=d8). Mean IL-6_CSFd8 concentrations were significantly higher in patients with VCSAH (7549 ± SD 4744 pg/ml) than in patients with cVSSAH (2482 ± SD 2395 pg/ml, p= 0.002) or SAH- (853 ± SD 649 pg/ml, p= 0.02). IL-6_CSF had good diagnostic potential on day 8 after SAH for diagnosing VCSAH (AUCd8= 0.852 [95%CI: 0.707; 0.997], threshold= 2900 pg/ml, sensitivity= 92.3%, specificity= 73.7%). Patients undergoing clipping or coiling showed no significant differences in the mean IL-6_CSF concentrations.

Conclusion: Time-dependent reference values of IL-6CSF for diagnosing VCSAH were introduced by this study. IL-6_CSF concentrations above the 90th percentile of aseptic courses (SAH- and cVSSAH) or IL-6_CSF concentrations above 2900 pg/ml after the 8th day are helpful for predicting VCSAH early.
