Acute hyperglycemia is associated with intraventricular extension among patients with spontaneous intracerebral hemorrhage

Abstract

Objective

Acute hyperglycemia following intracerebral hemorrhage (ICH) is associated with poor functional outcomes and may result from a neuroendocrine stress response. Given the proximity of neuroendocrine structures to the cerebral ventricles, we tested the hypothesis that intraventricular hemorrhage (IVH) is associated with hyperglycemia.

Materials and methods

A post-hoc analysis of the ICH Deferoxamine (i-DEF) trial was conducted to determine predictors of IVH. Variables with significant differences (p < 0.1) in univariable tests between patients with and without IVH were entered into a logistic regression model along with age, sex, diabetes, hyperglycemia (admission glucose ≥140 mg/dL), and baseline intraparenchymal hemorrhage (IPH) volume. This model was then applied to an independent cohort of consecutive non-traumatic ICH patients admitted to a single referral center (2007 to 2018).

Results

Among 294 patients in the i-DEF cohort with mean age 60 ± 12 years (IVH in 41 %), hyperglycemia (aOR 1.90, 95 % CI [1.06–3.38]), smoking history (aOR 1.90, 95 % CI [1.11–3.27]), and non-lobar ICH location (aOR 3.38, 95 % CI [1.49–7.69]) were independently associated with IVH. In the independent cohort consisting of 856 patients with mean age 71 ± 12 years (IVH in 37 %), hyperglycemia (aOR 2.23, 95 % CI [1.55–3.20]), non-lobar ICH location (aOR 2.50, 95 % CI [1.75–3.59]), and IPH volume (aOR 1.02, 95 % CI [1.01–1.02]) were associated with IVH.

Conclusions

Hyperglycemia is associated with IVH and may be a peripheral marker for the inflammatory response to hemorrhage within the ventricles. Further translational studies are needed to elucidate the pathophysiological basis for this phenomenon.
