Delayed Perihematomal Hypoperfusion is associated with Poor Outcome in Intracerebral Hemorrhage

Introduction: Post-stroke cognitive dysfunction (CD) affects at least 1/3 of acute ischemic stroke (AIS) patients when assessed at 3 months. Limited data exists on CD in intracerebral hemorrhage (ICH). The role of early, in-hospital cognitive screening using the brief Montreal Cognitive Assessment (mini MoCA) is being investigated at our center. Hypothesis: We assessed the rates of early CD in ICH and AIS and hypothesized that even minor deficits from these disorders causes significant CD. Methods: 1218 consecutive stroke patients admitted from 2/13 to 12/13 were reviewed; 610, 442 with AIS and 168 with ICH, with admission NIHSS and mini MoCAs were included in the final analyses. CD was defined as mini MoCA <9 (max 12). Poor outcome was defined as discharge mRS 4-6. Stroke severity was stratified by NIHSS score of 0-5, 6-10, 11-15, 16-20, 21-42 as in ECASS-I . Chi-squared tests and univariate logistic regression analyses were performed. Results: Baseline characteristics are shown in table 1. AIS and ICH groups were similar with regard to race, gender and stroke severity. ICH patients were younger, had longer stroke service lengths of stay and poorer outcomes than AIS patients (p=0.03, p<0.001, p<0.001). No difference was seen in rates of CD between AIS and ICH patients (60% vs. 57%, p=0.36, OR 1.2 (CI 0.8-1.7)). CD rates ranged from 36% for NIHSS 0-5 to 96% for 21-42 (figure 1). Older patients were twice as likely to have CD (p<0.001, OR 2.2 (CI 1.6 - 3.0)). Patients with CD had five times the odds of having a poor outcome compared to the cognitively intact (p<0.001, OR 5.2 (CI 3.4-7.7)). In univariate logistic regression analyses, age was a significant predictor of CD in AIS, but not in ICH (p= <0.001, p=0.06). Conclusion: Post-stroke CD is common across all severities and occurs at similar rates in AIS and ICH. More than 1/3 of patients with minor deficits (NIHSS 0-5) had CD in the acute hospital setting. Whether early CD is predictive of long term cognitive outcomes deserves further study.

Background and Purpose: lymphopenia is increasingly recognized as a consequence of acute illness and may predispose to infections. We investigated whether admission lymphopenia (AL) is associated with increased risk of infectious complications and poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). Methods: we analyzed a prospectively collected cohort of ICH patients ascertained between 1994 and 2015. Subjects were included if they had a lymphocyte count obtained within 24 h from onset and AL was defined as lymphocyte count<1000/uL. Infectious complications were assessed through retrospective chart review and the association between AL, infectious complications and mortality was investigated with a multivariable Cox regression and logistic regression respectively. Results: 2014 patients met the inclusion criteria (median age 75, males 54.0%) of whom 548 (27.2%) had AL and 605 (30.0%) experienced an infectious complication. Overall case fatality at 90 days was 36.9%. Patients with AL were more severely affected, as highlighted by larger hematoma volume, higher frequency of intraventricular hemorrhage and lower Glasgow Coma Scale score (all p<0.001). AL was independently associated with increased risk of pneumonia (Hazard Ratio [HR] 1.65, 95% confidence interval [CI] 1.32-2.05, p<0.001) and multiple infections (HR 1.75, 95% CI 1.22-2.51, p=0.002). The association with urinary tract infection, sepsis or other infections was not significant. AL was also an independent predictor of 90-day mortality (odds ratio 1.55, 95% CI 1.18-2.04, p=0.002) after adjusting for confounders. Conclusions: AL is common in ICH and associated with increased risk of infectious complications and poor outcome. Further studies will be needed to determine whether prophylactic antibiotics in ICH patients with AL can improve outcome.
