Introduction Microhemorrhages (MH) are lesions detected on radiological studies resulting from an underlying small-vessel angiopathy. We assesed the hypothesis that the presence of MH increases the risk of hematoma growth (HG) in patients with acute Intracerebral Hemorrhage (ICH). Methods We evaluated a series of patients in a prospective and multicentre study. We included patients with a spontaneous supratentorial ICH within the first 6 hours after symptom onset, that also had a follow-up CT 24-72 hours later and a MRI performed after a variable time after ICH. HG was defined as an increase >33% in the volume of hematoma on the follow-up CT, in comparison with the admission CT. The volume was calculated using the formula AxBxC/2. On MR scans we assessed the presence, number and distribution of MH. After differential diagnosis with other radiological lesions, MH were evaluated on echo-gradient sequences and defined as hypointense rounded lesions with a diameter <10mm. Statistical analysis: Bivariate tests with the whole sample and with the subgroup of patients with less than 3 hours from symptom onset. Results We studied 46 patients, whose mean age was 68.8±11.2 y and 68% were men. Mean baseline volume was 19.1±27.3 cc. We detected MH in 7/15 patients with HG and in 18/31 patients without HG (46.7% vs 58.1%, p=0.53). In the subgroup of patients with 10 MH, the risk of HG was higher than in patients with 0-10 MH (75% vs 28.6%, p=0.067), and this difference was significant when considering only patients with a <3 hours evolution (100% vs 31%, p=0.044). We did not observe any association between risk of HG and distribution of MH. Age and time to CT were equivalent in the two groups (with and without HG), either in the <6 or <3 hours subgroups. Conclusions In conclusion, in patients with hyperacute ICH, the presence of more than 10 MH increases the risk of HG. This is probably an indirect marker of a more severe underlying angiopathy.

Background: Hematoma expansion (HE) is common and associated with poor outcome in intracerebral hemorrhage (ICH) with unclear symptom onset (USO). Aims: We tested the association between non-contrast computed tomography (NCCT) markers and HE in this population. Methods: Retrospective analysis of patients with primary spontaneous ICH admitted at five centers in the United States and Italy. Baseline NCCT was analyzed for presence of the following markers: intrahematoma hypodensities, heterogeneous density, blend sign, and irregular shape. Variables associated with HE (hematoma growth > 6 mL and/or > 33% from baseline to follow-up imaging) were explored with multivariable logistic regression. Results: Of 2074 patients screened, we included 646 subjects (median age = 75, 53.9% males), of whom 178 (27.6%) had HE. Hypodensities (odds ratio (OR) = 2.67, 95% confidence interval (CI) = 1.79–3.98), heterogeneous density (OR = 2.16, 95% CI = 1.46–3.21), blend sign (OR = 2.28, 95% CI = 1.38–3.75) and irregular shape (OR = 1.82, 95% CI = 1.21–2.75) were independently associated with a higher risk of HE, after adjustment for confounders (ICH volume, anticoagulation, and time from last seen well (LSW) to NCCT). Hypodensities had the highest sensitivity for HE (0.69), whereas blend sign was the most specific marker (0.90). All NCCT markers were more frequent in early presenters (time from LSW to NCCT ⩽ 6 h, n = 189, 29.3%), and more sensitive in this population as well (hypodensities had 0.77 sensitivity). Conclusion: NCCT markers are associated with HE in ICH with USO. These findings require prospective replication and suggest that NCCT features may help the stratification of HE in future studies on USO patients.

Background and Purpose Early hematoma expansion (EHE) has been described in the first 48 hours. SHRINC is a phase 2 prospective safety trial whose primary objective is to assess the safety of pioglitazone (PIO) when administered to patients with spontaneous intracerebral hemorrhage (SICH) compared to standard care. A secondary objective is to characterize the changes in hematoma resolution and expansion over time. This prospective study addresses the natural history, clinical impact, and associated risk factors of late hematoma expansion (LEX) by serial magnetic resonance imaging (MRI) after SICH. Methods SHRINC aims to enroll 78 subjects between the ages of 18-80 with a SICH of ≥ 5 ml. This analysis includes the first 42 patients enrolled. Four subjects were excluded because they did not have an MRI after day 2. A baseline CTH was performed followed by an MRI within 24 hours of symptom onset. Hematoma volume (Hv) was measured on FLAIR sequences using a previously published semi-automated range of interest method. LEX was defined as an increase in Hv > 0.5 ml after the 48 hour MRI. Factors associated with LEX were evaluated with logistic regression. Longitudinal analyses were used for measurements taken over the follow up period. Results: Ten (26.3%) of 38 subjects displayed LEX. Eight subjects had LEX between day 2 to 14, and 4 between days 14 to 28. The median initial Hv was 16.1cc in LEX patients and 24.1cc in those without expansion (NEX) (p=0.23). Lower platelet counts (p=0.04) and BUN levels (p=0.03) were associated with LEX in univariate analysis. Multivariate analysis suggested that those with higher BUN levels were less likely to have LEX (OR=0.81; 95%CI 0.65-0.99). Blood pressure and EHE (13.2%) were not associated with LEX. There was no difference in neurological worsening (NIHSS increase ≥ 4), 6 month mRS or death between LEX and NEX. Conclusion: This is the first prospective study to address LEX with serial MRIs. LEX occurs between day 2 to 14 and day 14 to 28. Elevated BUN levels may decrease the likelihood of LEX. A limitation of our study is that the effect of PIO on LEX could not be evaluated because SHRINC is a blinded trial. Further studies will assess the pathophysiology of LEX and its potential implications in clinical trials evaluating hematoma growth and resolution.

Background and Purpose: The computed tomography angiography or contrast-enhanced computed tomography based spot sign has been proposed as a biomarker for identifying on-going hematoma expansion in patients with acute intracerebral hemorrhage. We investigated, if spot-sign positive participants benefit more from tranexamic acid versus placebo as compared to spot-sign negative participants. Methods: TICH-2 trial (Tranexamic Acid for Hyperacute Primary Intracerebral Haemorrhage) was a randomized, placebo-controlled clinical trial recruiting acutely hospitalized participants with intracerebral hemorrhage within 8 hours after symptom onset. Local investigators randomized participants to 2 grams of intravenous tranexamic acid or matching placebo (1:1). All participants underwent computed tomography scan on admission and on day 2 (24±12 hours) after randomization. In this sub group analysis, we included all participants from the main trial population with imaging allowing adjudication of spot sign status. Results: Of the 2325 TICH-2 participants, 254 (10.9%) had imaging allowing for spot-sign adjudication. Of these participants, 64 (25.2%) were spot-sign positive. Median (interquartile range) time from symptom onset to administration of the intervention was 225.0 (169.0 to 310.0) minutes. The adjusted percent difference in absolute day-2 hematoma volume between participants allocated to tranexamic versus placebo was 3.7% (95% CI, −12.8% to 23.4%) for spot-sign positive and 1.7% (95% CI, −8.4% to 12.8%) for spot-sign negative participants ( P heterogenity =0.85). No difference was observed in significant hematoma progression (dichotomous composite outcome) between participants allocated to tranexamic versus placebo among spot-sign positive (odds ratio, 0.85 [95% CI, 0.29 to 2.46]) and negative (odds ratio, 0.77 [95% CI, 0.41 to 1.45]) participants ( P heterogenity =0.88). Conclusions: Data from the TICH-2 trial do not support that admission spot sign status modifies the treatment effect of tranexamic acid versus placebo in patients with acute intracerebral hemorrhage. The results might have been affected by low statistical power as well as treatment delay. REGISTRATION: URL: http://www.controlled-trials.com ; Unique identifier: ISRCTN93732214.

Background: Alcohol overuse (AO) is considered a cause of spontaneous intracerebral hemorrhage (ICH), but the clinical and outcome characteristics of these patients (AO+ICH) are not well known. Methods: All patients with ICH admitted from January 2005 to June 2015 to a single university tertiary stroke center were prospectively studied and followed up during 5 years. Demographic features, radiological characteristics, and clinical outcome of patients with acute ICH and previous heavy alcohol intake (>40 gr/day or >300 gr/week) were analyzed. Results: During the study period, 609 patients with ICH were admitted. Nineteen patients were excluded because data on alcohol intake was not available. At admission, 83 patients (13.6%) were identified with AO (22.7% of men vs 2.9% of women; p< 0.0001) and was more frequent in younger patients (mean age, 63.11 years, compared to 72.7 years overall; p< 0.0001). Smoking was associated with AO (63,9% vs 13,8% non-AO; p< 0.0001) but not significant differences were found according with cardiovascular risk factors (dyslipidemia, diabetes and hypertension). ICH score was lower in the AO group (1.3 vs 1.8, p= 0.009) and deep ICH were more frequent (p= 0.036), compared to non-AO. Adjusted by sex, age, and high blood pressure, a trend in favor of increased deep ICH in AO patients remained (HR: 1.68 [95% CI: 0.92-3.05], p= 0.086). Adjusted mortality at 3-month, 12-month, and 5-year follow-up was similar in both groups. Conclusions: AO was present in 13.6% of ICH patients. These patients were an average of 11.5 years younger, predominantly men, and smokers, compared to the non-AO group. Adjusted short-term and long-term mortality was similar in AO and non-AO groups.

Background: Although the current AHA guidelines recommend maintaining systolic blood pressure (SBP) below 180 mmHg in acute intracerebral hemorrhage (ICH), little is known about the relationships between different therapeutic target thresholds and hematoma growth (HG). Therefore, we aimed to investigate the impact of potential SBP treatment thresholds on HG in patients with acute ICH. Methods: This study was a secondary analysis of data prospectively collected during a previously reported study of the impact of blood pressure (BP) on HG in 106 patients with acute (<6 hours) supratentorial ICH. Patients underwent baseline and 24-hour computed tomography scans, and noninvasive BP monitoring at 15 minutes interval over first 24 hours. SBP loads were defined as the percentage of 24-hour SBP monitoring values exceeding 140, 150, 160, 170, 180, 190, and 200 mmHg. HG was defined as a relative enlargement greater than 33% or an absolute expansion more than 6 mL at 24 hours. Results: Patients who experienced HG (34%) presented higher SBP loads in all thresholds, reaching statistical significance in 170, 180, and 190 thresholds, but not in the others (Figure). Whilst SBP load thresholds were correlated neither with baseline nor 24-hour ICH volumes, highest (170 to 200) but not lowest (140 to 160) SBP load thresholds were significantly correlated with the amount of both relative and absolute hematoma enlargement at 24 hours (p<0.05). In multivariate analyses, both SBP 170-load (OR 1.034, 95% CI 1.001-1.070, p=0.048) and 180-load (OR 1.052, 95% CI 1.010-1.097, p=0.016) were independently related to HG. Conclusions: In patients with acute supratentorial ICH, those who experience HG present higher SBP load from 140 to 200 mmHg thresholds. More intensive SBP-lowering treatment than guidelines recommendations is needed, at least below 170 mmHg, in order to minimize the deleterious effect of higher SBP on HG.

Background: Data on cognitive impairment after acute intracerebral hemorrhage (ICH) are limited. This study is aimed at determining the frequency and predictors of cognitive impairment among participants of the pilot phase, Intensive Blood Pressure (BP) Reduction in Acute Cerebral Hemorrhage Trial (INTERACT1). Methods: INTERACT1 was an open randomized trial of early intensive (target systolic BP <140 mm Hg) compared with contemporaneous guideline-recommended BP lowering in 404 patients with elevated systolic BP (150–220 mm Hg) within 6 h of ICH onset. Cognitive impairment was defined by scores ≤24 on the Mini-Mental State Examination (MMSE) assessed by interview on follow-up at 90 days. Results: A total of 231 (64.5%) of 358 90-day survivors had MMSE scores for analyses, and 75 (32.5%) had cognitive impairment. In multivariable analysis, older age (OR 2.48, 95% CI 1.73–3.56 per 10-year increase; p < 0.001), female sex (OR 2.06, 95% CI 1.00–4.23; p = 0.049), prior ICH (OR 2.87, 95% CI 1.08–7.65; p = 0.035), high baseline National Institute of Health Stroke Scale score (OR 1.06, 95% CI 1.00–1.13; p = 0.044), and high mean systolic BP over the first 24 h post-randomization (OR 1.34, 95% CI 1.07–1.68/10 mm Hg increase; p = 0.011) were independently associated with cognitive impairment. Conclusions: One third of patients have significant cognitive impairment early after ICH, which is more frequent in the elderly, females, those with prior ICH, and more severe initial neurological deficit and with persistently high early systolic BP.
