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

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.
