Background and Purpose: We present a retrospective analysis of patients who underwent minimally invasive endoscopic intracerebral hemorrhage (ICH) evacuation to identify variables that were associated with long-term outcome. Methods: Minimally invasive endoscopic ICH evacuation was performed on patients with supratentorial ICH who fit prespecified clinical inclusion and exclusion criteria. Demographic, clinical, and radiographic factors previously demonstrated to impact functional outcome in ICH were included in a univariate analysis to identify factors associated with favorable outcome (modified Rankin Scale score, 0–3) at 6 months. Factors associated with a favorable outcome in the univariate analysis ( P ≤0.20) were included in a multivariate logistic regression analysis with the same dependent variable. Results: Ninety patients underwent MIS endoscopic ICH evacuation within 72 hours of ictus. In a multivariate analysis, factors associated with good long-term functional outcome included time to evacuation (per hour; OR, 0.95 [95% CI, 0.92–0.98], P =0.004), age (per decade, odds ratio [OR], 0.49 [95% CI, 0.28–0.77], P =0.005), presence of intraventricular hemorrhage (OR, 0.15 [95% CI, 0.04–0.47], P =0.002), and lobar location (OR, 18.5 [95% CI, 4.5–103], P =0.0005). Early evacuation was not associated with an increased risk of rebleeding. Conclusions: Young age, lack of intraventricular hemorrhage, lobar location, and time to evacuation were independently associated with good long-term functional outcome in patients undergoing minimally invasive endoscopic ICH evacuation. The OR for time to evacuation suggests that for each additional hour, there was a 5% reduction in the odds of achieving a favorable outcome.

Introduction: Preclinical data have demonstrated a time-dependent benefit to early intracerebral hemorrhage (ICH) evacuation while clinical data have been less clear. Here we present long term functional outcome after minimally invasive endoscopic intracerebral hemorrhage evacuation with a focus on time to evacuation (TTE). Methods: Minimally invasive endoscopic ICH evacuation was performed on patients with supratentorial ICH who fit prespecified clinical inclusion and exclusion criteria agreed upon by a multidisciplinary group of physicians in the health care system. Retrospective analysis of prospectively collected data was performed on patients who were treated from December 2015 to October 2018. Demographic, clinical, and radiographic factors previously demonstrated to impact functional outcome in ICH were included in a multivariate logistic regression to identify factors predicting favorable outcome (modified Rankin Scale 0-3) at 6 months post-hemorrhage. Results: Ninety patients underwent MIS endoscopic ICH evacuation within 72 hours of ictus. In a multivariate analysis, factors that were identified to predict a positive outcome included age (per decade, OR 0.48, 95% CI 0.28-0.82) presence of intraventricular hemorrhage (OR 0.23, 95% CI 0.07-0.79), cortical location (OR 19.89, 95% CI 3.37-117.39), early evacuation (per hour, OR 0.95, 95% CI 0.92-0.99). Patients who underwent evacuation within 24 hours were 5 times more likely to achieve a favorable outcome (OR 5.29, 95% CI 1.52-18.41). Early evacuation did not correlate with increased risk of rebleeding. Conclusion: Time to evacuation significantly impacts long term outcome in minimally invasive endoscopic ICH evacuation. Every one hour evacuation is delayed results in a 5% reduction in the odds of achieving a favorable long-term outcome.

Abstract INTRODUCTION Preclinical and preliminary clinical data suggests that early minimally invasive intracerebral hemorrhage evacuation may convey a functional outcome benefit. Ongoing clinical trials permit an operative window extending out to 72 h. Here we present long term functional outcome after MIS endoscopic ICH evacuation with a focus on time to evacuation. METHODS Minimally invasive endoscopic ICH evacuation was performed on patients with supratentorial ICH who fit previously published clinical criteria including age = 18, National Institutes of Health Stroke Scale (NIHSS) = 6, hematoma volume = 15, and baseline modified Rankin Score (mRS) = 3 with a CTA negative for vascular malformation. Retrospective review was performed on patients who were treated in a single health system from December 2015 to August 2018. Demographic, clinical and radiographic previously demonstrated to impact ICH outcome were included in a multivariate logistic regression to identify factors predicting poor outcome (modified Rankin scale (mRS) 4-6) at 6 mo. RESULTS A total of 97 patients underwent minimally invasive endoscopic ICH evacuation. In a multivariate analysis, factors that predicted poor outcome included age (OR 1.81 (CI 1.15-3.08) P = .016), deep location (OR 11.1 (2.41-67.8) P = .004), presence of intraventricular hemorrhage (OR 5.81 (1.765-22.39) P = .006) and increased time to evacuation measured in hours (OR 1.048 (CI 1.017-1.084) P = .004). CONCLUSION Time to evacuation significantly impacts long term outcome in minimally invasive endoscopic ICH evacuation. Every minute counts.

Baseline Characteristics

Background and Purpose: Hemispheric location might influence outcome after intracerebral hemorrhage (ICH). INTERACT suggested higher short-term mortality in right hemispheric ICH, yet statistical imbalances were not addressed. This study aimed at determining the differences in long-term functional outcome in patients with right- vs. left-sided ICH with a priori-defined sub-analysis of lobar vs. deep bleedings. Methods: Data from a prospective hospital registry were analyzed including patients with ICH admitted between January 2006 and August 2014. Data were retrieved from institutional databases. Outcome was assessed using the modified Rankin Scale (mRS) score. Outcome measures (long-term mortality and functional outcome at 12 months) were correlated with ICH location and hemisphere, and the imbalances of baseline characteristics were addressed by propensity score matching. Results: A total of 831 patients with supratentorial ICH (429 left and 402 right) were analyzed. Regarding clinical baseline characteristics in the unadjusted overall cohort, there were differences in disfavor of right-sided ICH (antiplatelets: 25.2% in left ICH vs. 34.3% in right ICH; p < 0.01; previous ischemic stroke: 14.7% in left ICH vs. 19.7% in right ICH; p = 0.057; and presence/extent of intraventricular hemorrhage: 45.0% in left ICH vs. 53.0% in right ICH; p = 0.021; Graeb-score: 0 [0-4] in left ICH vs. 1 [0-5] in right ICH; p = 0.017). While there were no differences in mortality and in the proportion of patients with favorable vs. unfavorable outcome (mRS 0-3: 142/375 [37.9%] in left ICH vs. 117/362 [32.3%] in right ICH; p = 0.115), patients with left-sided ICH showed excellent outcome more frequently (mRS 0-1: 64/375 [17.1%] in left ICH vs. 43/362 [11.9%] in right ICH; p = 0.046) in the unadjusted analysis. After adjusting for confounding variables, a well-balanced group of patients (n = 360/hemisphere) was compared showing no differences in long-term functional outcome (mRS 0-3: 36.4% in left ICH vs. 33.9% in right ICH; p = 0.51). Sub-analyses of patients with deep vs. lobar ICH revealed also no differences in outcome measures (mRS 0-3: 53/151 [35.1%] in left deep ICH vs. 53/165 [32.1%] in right deep ICH; p = 0.58). Conclusion: Previously described differences in clinical end points among patients with left- vs. right-hemispheric ICH may be driven by different baseline characteristics rather than by functional deficits emerging from different hemispheric functions affected. After statistical corrections for confounding variables, there was no impact of hemispheric location on functional outcome after ICH.

Background: Data on clinical characteristics and outcome of patients with intracerebral hemorrhage (ICH) and concomitant systemic cancer disease are very limited. Methods: Nine hundred and seventy three consecutive primary ICH patients were analyzed using our prospective institutional registry over a period of 9 years (2006-2014). We compared clinical and radiological parameters as well as outcome - scored using the modified Rankin Scale (mRS) and analyzed in a dichotomized fashion as favorable outcome (mRS = 0-3) and unfavorable outcome (mRS = 4-6) - of ICH patients with and without cancer. Relevant imbalances in baseline clinical and radiological characteristics were adjusted using propensity score (PS) matching. Results: Prevalence of systemic cancer among patients with ICH was 8.5% (83/973). ICH patients with cancer were older (77 [70-82] vs. 72 [63-80] years; p = 0.002), had more often prior renal dysfunction (19/83 [22.9%] vs.107/890 [12.0%]; p = 0.005), and smaller hemorrhage volumes (10.1 [4.8-24.3] vs. 15.3 [5.4-42.9] mL; p = 0.017). After PS-matching there were no significant differences neither in mortality nor in functional outcome both at 3 months (mortality: 33/81 [40.7%] vs. 55/158 [34.8%]; p = 0.368; mRS = 0-3: 28/81 [34.6%] vs. 52/158 [32.9%]; p = 0.797) and 12 months (mortality: 39/78 [50.0%] vs. 70/150 [46.7%]; p = 0.633; mRS = 0-3: 25/78 [32.1%] vs. 53/150 [35.3%]; p = 0.620) among patients with and without concomitant systemic cancer. ICH volume tended to be highest in patients with hematooncologic malignancy and smallest in urothelial cancer. Conclusions: Patients with ICH and concomitant systemic cancer on average are older; however, they show smaller ICH volumes compared to patients without cancer. Yet, mortality and functional outcome is not different in ICH patients with and without cancer. Thus, the clinical history or the de novo diagnosis of concomitant malignancies in ICH patients should not lead to unjustified treatment restrictions.

Introduction: Data from the Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study previously reported racial/ethnic differences in discharge disposition after ICH hospitalization to home-like environments vs. medical facilities. We sought to explore how discharge disposition affects functional outcome for ICH patients with disability at time of hospital discharge. Methods: ERICH is a multi-center, prospective case-control study of ICH among whites, blacks, and Hispanics. Patients included in this analysis had pre-stroke modified Rankin Scale (mRS) < 3, available ICH volume measurements (log transformed), and mRS of 2-5 at discharge. The mRS at 3 months post onset was the primary outcome variable. Logistic regression was used to model the probability of 3-month functional disability (mRS≥3) against discharge disposition, adjusting for ICH score and dementia. Results: Between 08/2010 and 3/2015, 2964 ICH cases were enrolled, of whom 1627 qualified for analysis. Univariate analysis examined demographics, past medical history, social status (education level, marital status, employment), and type of insurance. In multivariate analysis, higher age, lower GCS, higher discharge mRS, non-lobar ICH location, higher ICH volume, presence of IVH, and history of dementia were independently associated with increased risk of mRS≥3 at 3 months. In a multivariate model that controlled for ICH score, patients who were mRS=3 at hospital discharge were more likely to be mRS ≥ 3 at 3 months if discharged to a medical facility rather than to home (p=.0153, OR 2.7, CI 1.2-6.2); additional independent predictors of 3-month mRS≥3 were presence of IVH (p=.002, OR 3.5, CI 1.8-6.6) and dementia (p=.04, OR 3.8, CI 1.1-13.7). However, patients who were mRS=4 at discharge were equally as likely to be mRS≥3 at 3 months, whether discharged home or to a medical facility (p=0.599, OR 0.9, CI 0.5-1.5). Conclusion: ICH patients with moderate disability at hospital discharge were more likely to have a favorable functional outcome at 3 months if discharged to a home environment vs. a medical facility. Future analysis is needed to look at the rate of complications for ICH patients at medical facilities vs. home-like environments that may affect 3-month outcome.

Abstract BACKGROUND: Recent studies have focused on antiplatelet (AP) use in intracerebral hemorrhage (ICH) patients. Several outcome predictors have been debated, but influences on mortality and outcome still remain controversial, especially for different ICH locations. OBJECTIVE: To investigate the characteristics and functional outcome of ICH patients with reported regular AP use according to hemorrhage locations. METHODS: This retrospective analysis included 210 consecutive spontaneous ICH patients. Clinical data including the preadmission status, initial presentation, neuroradiological data, treatment, and outcome were evaluated. Analyses were calculated for AP use vs non-AP use according to hematoma locations, and multivariate models were calculated for hematoma expansion and unfavorable (modified Rankin Scale = 4–6) long-term functional outcome (at 1 year). RESULTS: For all AP users ICH volume was significantly larger, 27.7 mL (interquartile range 7.4-66.1) vs 16.8 mL (interquartile range 4.2-44.7); (P = .032). Analyses showed an increased mortality for AP users at 90 days and 1 year (P = .036; P = .008). Multivariately, for all ICH patients, prior AP use was independently associated with hematoma expansion (odds ratio [OR] 3.61; P = .026) and poorer functional outcome at 1 year (OR 3.82, P = .035). In deep ICH patients, AP use was an independent predictor of an unfavorable functional outcome at 1 year (OR 4.75, P = .048). CONCLUSION: Hematoma expansion and more frequent unfavorable long-term functional outcome were independently associated with prior AP use for all patients, and in deep ICH patients AP use was an independent predictor of an unfavorable long-term functional outcome.

ObjectiveTo investigate whether the systemic inflammatory response syndrome (SIRS) without infection as surrogate of a systemic immune response is associated with poor long-term functional outcome in patients with spontaneous intracerebral hemorrhage (ICH).MethodsWe analyzed consecutive patients with spontaneous ICH from our prospective cohort study (2018–2015). SIRS was defined according to standard criteria: i.e., 2 or more of the following parameters during hospitalization: body temperature <36°C or >38°C, respiratory rate >20 per minute, heart rate >90 per minute, or white blood cell count <4,000/μL or >12,000/μL in the absence of infection. The primary outcome consisted of the modified Rankin Scale (mRS) at 3 and 12 months investigated by adjusted ordinal shift analyses. Bias and confounding were addressed by propensity score matching and multivariable regression models.ResultsOf 780 patients with ICH, 21.8% (n = 170) developed SIRS during hospitalization. Patients with SIRS showed more severe ICH compared with those without; i.e., larger ICH volumes (18.3 cm3, interquartile range [IQR 4.6–47.2 cm3] vs 7.4 cm3, IQR [2.4–18.6 cm3]; p < 0.01), increased intraventricular hemorrhage (57.6%, n = 98/170 vs 24.8%, n = 79/319; p < 0.01), and poorer neurologic admission status (NIH Stroke Scale score 16, IQR [7–30] vs 6, IQR [3–12]; p < 0.01). ICH severity-adjusted analyses revealed an independent association of SIRS with poorer functional outcome after 3 (OR 1.80, 95% CI [1.08–3.00]; p = 0.025) and 12 months (OR 1.76, 95% CI [1.04–2.96]; p = 0.034). Increased ICH volumes on follow-up imaging (OR 1.38, 95% CI [1.01–1.89]; p = 0.05) and previous liver dysfunction (OR 3.01, 95% CI [1.03–10.19]; p = 0.04) were associated with SIRS.ConclusionsIn patients with ICH, we identified SIRS to be predictive of poorer long-term functional outcome over the entire range of mRS estimates. Clinically relevant associations with SIRS were documented for previous liver dysfunction and hematoma enlargement.

The long-term functional outcome of acute basilar artery occlusion (BAO) patients who received modern endovascular therapy (EVT) is unclear. We sought to assess the long-term functional outcome of BAO patients treated with EVT and determine the prognostic factors associated with favorable outcome. We enrolled consecutive BAO patients who received EVT between December 2012 and December 2018 in this observational study. Baseline characteristics and outcomes were presented. Multivariable logistic regression analysis was performed to identify the prognostic factors associated with long-term outcome. Among the 177 BAO patients included in this study, 80 patients (45.2%) obtained favorable outcome and 97 patients (54.8%) had unfavorable outcome at long-term follow-up with a median observation time of 12 months (interquartile range, 3–19). A total of 67 patients (37.9%) died. National Institutes of Health Stroke Scale (NIHSS), posterior circulation Alberta Stroke Program Early Computed Tomography Score (pc-ASPECTS), time from stroke onset to recanalization, and recanalization condition were identified as independent predictors for long-term outcome. Over 40% of BAO patients who were treated with modern EVT achieved favorable outcome at long-term follow-up. NIHSS, pc-ASPECTS, time from stroke onset to recanalization, and recanalization condition were identified as independent prognostic factors of long-term outcome.

Risk Of Retinopathy

Background:Hydroxychloroquine (HCQ) is commonly used for the treatment of various autoimmune diseases. The medication is generally well-tolerated. However, long-term use after 5 years may increase the risk of retinopathy. One study in 2014 has demonstrated the risk can be as high as 7.5%. Optical Coherence Tomography (OCT) has become a major modality in screening retinopathy.Objectives:To evaluate the prevalence of retinal toxicity among patients using hydroxychloroquine and to determine various risk factors associated with hydroxychloroquine-associated retinal toxicity.Methods:We performed a retrospective chart review on a cohort of adult patients with long-term use (≥ 5 years cumulative) of HCQ between January 1st, 2011 to December 31st, 2018 from the Kaiser Permanente San Bernardino County and Riverside medical center areas in Southern California, USA. Patients were excluded if they had previously been diagnosed with retinopathy prior to hydroxychloroquine use, were deceased, or had incomplete OCT exam. Our primary endpoint was the prevalence of patients who developed retinal toxicity detected by OCT, and later confirmed by retinal specialist. Potential risk factors (age, duration of therapy, daily consumption per actual body weight, cumulative dose, confounding diseases and medication) for developing retinopathy were also evaluated. Univariable and multivariable logistic regression analyses were used to determine risk factors associated with retinal toxicity.Results:Among 676 patients exposed to more than 5 years of HCQ, the overall prevalence of retinal toxicity was 6.8%, and ranged from 2.5% to 22.2% depending on the age, weight-based dosing, duration of use and cumulative dose. Duration of therapy for 10 years or more increased risk of retinopathy by approximately 5 to 19 folds. Similarly, weight-based dose of 7 mg/kg/day or greater was assciated with increased risk of retinopathy by approximately 5 times. Patients with cumulative dose of 2000 grams or more had greater than 15 times higher risk of developing retinopathy. Duration of use for10 years or more (odd ratio 4.32, 95% CI 1.99 – 12.49), age (odd ratio 1.04; 95% CI 1.01 - 1.08), cumulative dose of more than 1500 g (odd ratio 7.4; 95% CI 1.40 – 39.04) and atherosclerosis of the aorta (odd ratio 2.59; 95% CI, 1.24 – 5.41) correlated with higher risk of retinal toxicity.Conclusion:The overall prevalence of retinopathy was 6.8%. Regular OCT screening, especially in patients with hydroxychloroquine use for more than 10 years, daily intake > 7 mg/kg, or cumulative dose > 1500 grams is important in detecting hydroxychloroquine-associated retinal toxicityReferences:[1]Hobbs HE.
