Development of a core outcome set for hypertensive intracerebral hemorrhage in clinical trials of traditional Chinese medicine: a study protocol.

BACKGROUND: Intracerebral hemorrhage (ICH) is a devastating disease, its mortality and disability rate are high. In China, hypertensive intracerebral hemorrhage (HICH) is responsible for 75% of all the cases of primary ICH. A lot of randomized controlled trials (RCTs) of traditional Chinese medicine (TCM) for treating HICH have been carried out. However, these RCTs have a lot of problems, such as heterogeneous outcomes, non-uniform point of measurement. These lead to systematic review/meta-analysis only can include a small number of studies. And outcome measures did not take the wishes of patients and other stakeholders into account. The aim of this study is to establish the core outcome set (COS) for future TCM clinical trials of HICH. METHODS AND ANALYSIS: First, we will develop a long list of general outcomes by making systematic literature review and semi-structured interviews. Then healthcare professionals and patients with HICH will be invited to participate in two rounds of the Delphi survey to determine the importance of the outcome. Finally, a face-to-face consensus meeting will be conducted to determine the final COS of HICH, including what outcomes should be measured and when and how to measure the outcomes. RESULTS: We aim to develop a COS that includes TCM core syndrome for HICH to determine what outcomes should be reported and when and how to measure them. CONCLUSION: By doing this, we can increase the reporting consistency and reduce the reporting bias in the outcome, which leads to the reuse of research data in meta-analysis and the making of informed healthcare decisions. ETHICS AND DISSEMINATION: The entire project has received approval from the Ethics Committee of Xiyuan Hospital, China Academy of Chinese Medical Sciences. The final COS will be published and reported at the national and international conferences. TRIAL REGISTRATION: This study is registered with the Core Outcome Measures in Effectiveness Trials database as study 1475 . Registered on December 2019.

Effect of BMI on Central Arterial Reflected Wave Augmentation Index, Toe-Brachial Index, Brachial-Ankle Pulse Wave Velocity and Ankle-Brachial Index in Chinese Elderly Hypertensive Patients with Hemorrhagic Stroke.

BACKGROUND: Hypertensive cerebral hemorrhage seriously endangers the health of the elderly. However, the relationship between obesity and arterial elasticity in hypertensive cerebral hemorrhage remains to be clarified. The purpose of our study is to explore the associations between body mass index (BMI) and central arterial reflected wave augmentation index (cAIx), toe-brachial index (TBI), brachial-ankle pulse wave velocity (baPWV), and ankle-brachial index (ABI) in the elderly hypertensive patients with hemorrhagic stroke. MATERIALS AND METHODS: A total of 502 elderly hypertensive patients with hemorrhagic stroke and 100 healthy controls were collected. According to the BMI, patients were divided into normal BMI, overweight, obesity, and obese groups. The multivariate logistic regression model was used to establish a risk model for elderly hypertensive hemorrhagic stroke. RESULTS: Compared with the normal BMI group, systolic blood pressure (SBP), diastolic blood pressure (DBP), cAIx, and baPWV in the abnormal BMI group were significantly increased (P < 0.05), while TBI and ABI were significantly decreased (P < 0.05). Logistic regression showed that BMI (OR = 1.031, 95%CI: 1.009-1.262), cAIx (OR = 1.214, 95%CI: 1.105-1.964), TBI (OR = 0.913, 95%CI: 0.885-0.967), baPWV (OR = 1.344, 95%CI: 1.142-2.147), and ABI (OR = 0.896, 95%CI: 0.811-0.989) are important factors for the occurrence of hemorrhagic stroke in the elderly hypertensive patients. ROC curve analysis showed that the AUC of cAIx, TBI, baPWV, ABI, and BMI were 0.914, 0.797, 0.934, 0.833, and 0.608, respectively. The final prediction model of hemorrhagic stroke elderly hypertensive patients was Y(P)= 65.424 + 0.307(cAIx) - 13.831(TBI) + 0.012(baPWV) - 0.110(ABI) + 0.339(BMI). CONCLUSIONS: Obesity is associated with decreased arterial elasticity. Therefore, reasonable weight management of the elderly may be of great significance for reducing the risk of hemorrhagic stroke in patients with hypertension.

Arrival blood pressure in hypertensive and non-hypertensive spontaneous intracerebral hemorrhage.

BACKGROUND AND PURPOSE: Hypertension is a known risk factor for intracerebral hemorrhage (ICH), but it is unclear whether blood pressure (BP) at hospital arrival can be used to distinguish hypertensive ICH from non-hypertensive etiologies. PATIENTS AND METHODS: We performed a single-center cohort study using data from consecutive ICH patients over 12 months. ICH characteristics including etiology were prospectively adjudicated by two attending neurologists. Using adjusted linear regression models, we compared first recorded systolic BPs (SBP) and mean arterial pressures (MAP) in patients with hypertensive vs. other ICH etiologies. We then used area under the ROC curve (AUC) analysis to determine the accuracy of admission BP in differentiating between hypertensive and non-hypertensive ICH. RESULTS: Of 311 patients in our cohort (mean age 70.6 ± 15.6, 50% male, 83% white), the most frequent ICH etiologies were hypertension (50%) and cerebral amyloid angiopathy (CAA; 22%). Mean SBP and MAP for patients with hypertensive ICH was 175.1 ± 32.9 mmHg and 120.4 ± 22.9 mmHg, respectively, compared to 156.4 ± 28.0 mmHg and 109.6 ± 20.3 mmHg in non-hypertensive ICH (p < .001). Adjusted models showed that hypertensive ICH patients had higher BPs than those with CAA (mean SBP difference 10.7 mmHg [95% CI 0.8-20.5]; mean MAP difference 8.1 mmHg [1.1-15.0]) and especially patients with other non-CAA causes (mean SBP difference 23.9 mmHg [15.3-32.4]; mean MAP difference 14.5 mmHg [8.5-20.6]). However, on a patient-level, arrival BP did not reliably discriminate between hypertensive and non-hypertensive etiologies (AUC 0.660 [0.599-0.720]). CONCLUSIONS: Arrival BP differs between hypertensive and non-hypertensive ICH but should not be used as a primary determinant of etiology, as hypertension may be implicated in various subtypes of ICH.

Hypertension is a Leading Cause of Nontraumatic Intracerebral Hemorrhage in Young Adults.

OBJECTIVE: To evaluate the etiology and discharge outcome of nontraumatic intracerebral hemorrhage (ICH) in young adults admitted to a comprehensive stroke center. METHODS: A retrospective chart review was performed on patients with a discharge diagnosis of nontraumatic ICH admitted from 7/1/2011 to 6/30/2016. Data was collected on demographics, clinical history, ICH score, hemorrhage location, do-not-resuscitate (DNR) orders, likely etiology, and discharge disposition. Categorical data was reported as percentage. Chi-squared test was performed to evaluate association of location of ICH, etiology of ICH, and ICH score with the discharge outcome. RESULTS: Sixty-three patients met the study criteria, with mean age 35.4 ± 6.4 years including 26 (41%) women and 40 (64%) whites. Headache (65%) and change in mental status (48%) were the most common presenting symptoms. Hemorrhage was most commonly seen in the deep structures in 29 (46%) patients followed by lobar ICH in 14 (22%) patients. The most common etiology of ICH was hypertension in 23 (37%) patients, followed by vascular abnormalities in 18 (29%) patients. Forty-two (67%) had good outcome defined as discharge to home (n = 25) or acute inpatient rehabilitation (n = 17). Twenty-one (33%) patients had bad outcome with discharge to skilled nursing facility (n = 6), hospice (n = 1) or died in the hospital (n = 14). Hospital DNR orders were noted in 11 (18%) patients. Higher ICH score (P < .0001) and use of DNR orders (P < .0001) were associated with bad outcome. All 11 patients with DNR orders died in the hospital. Location or etiology of hemorrhage were not associated with discharge outcome. CONCLUSIONS: Hypertension, a modifiable risk factor, is a major cause of nontraumatic ICH in young adults. Aggressive management of hypertension is essential to halt the recent increased trends of ICH due to hypertension. Early DNR orders may need to be cautiously used in the hospital.

Clinical Research of Early Hyperbaric Oxygen Therapy on Patients with Hypertensive Cerebral Hemorrhage After Craniotomy.

AIM: To observe the effect of early hyperbaric oxygen (HBO) therapy on the improvement of consciousness and prognosis of patients with severe brain damages after craniocerebral craniotomy. MATERIAL AND METHODS: Eighty-one patients who had cerebral hemorrhage and underwent clearance of hematoma and decompressive craniectomy from August 2013 to August 2016 were retrospectively analyzed. The patients were divided into HBO and non-HBO therapy groups. The treatment effects were scored and subjected to corresponding statistical analysis. RESULTS: There were significant differences in the Glasgow coma scale (GCS) scores at 3 and 5 weeks (t=2.293 and t=3.014, respectively, p < 0.05), and in Glasgow outcome scale (GOS) scores at 5 weeks and 3 months between the two groups (p < 0.05). CONCLUSION: Early HBO therapy could improve the consciousness and prognosis of patients with cerebral hemorrhage after craniotomy.

Intensive blood pressure control reduces the risk of progressive hemorrhage in patients with acute hypertensive intracerebral hemorrhage: A retrospective observational study.

OBJECTIVE: To investigate the impact of intensive blood pressure control on progressive intracerebral hemorrhage and outcome in patients with high blood pressure and intracerebral hemorrhage. PATIENTS AND METHODS: A retrospective study was conducted recruiting 659 patients with acute hemorrhagic stroke between Jan. 2012 and May 2018. Patients recruited before May 2015 were treated with a target systolic level of <180 mm Hg, while those recruited after May 2015 received intensive blood pressure control treatment with a target systolic level of <140 mm Hg within 1 h. Uni- and multi-variate analysis were conducted to illustrate the association between intensive blood pressure control and progressive intracerebral hemorrhage. Mortality, rates of operation, length of ICU stay, modified Rankin scores at 90 days, and the rate of serious adverse events were also compared between the two groups. RESULTS: A total of 351 and 308 patients with acute hypertensive intracerebral hemorrhage were recruited before and after May 2015, respectively. Progressive intracerebral hemorrhage was identified among 111 out of 659 patients. Patients who received intensive blood pressure control showed a statistically lower rate of hematoma enlarging (43 of 308, 13.9% vs. 74 of 351, 21.1%, p = 0.018). The rates of operation and modified Rankin scores at 90 days were statistically lower with intensive blood control, while the mortality, length of ICU stay and rate of serious adverse events were similar between the two groups. Intensive BP control is an independent factor in predicting hematoma growing, with a more favorable discrimination (AUC = 0.889; 95%CI, 0.859-0.917) than other two models (AUC = 0.821; 95%CI, 0.791-0.852; and AUC = 0.635; 95%CI, 0.588-0.682). CONCLUSION: Intensive blood pressure control reduce the risk of progressive intracerebral hemorrhage and improved functional outcomes in patients with acute hemorrhagic stroke.

Therapeutic Approach to Hypertensive Emergencies: Hemorrhagic Stroke.

Arterial hypertension represents the most important risk factor for ischemic and haemorrhagic stroke, and an acute hypertensive response is often observed in patients with intracranial haemorrhage (ICH). Available data indicate that the vast majority (> 70%) of patient with acute ICH have a systolic BP above 140 mmHg at the time of presentation in the ED; about 20% have SBP values above 180 mmHg. Severe BP elevation in the presence of ICH represents a hypertensive emergency, and worsening of clinical conditions is not infrequent in the first hours after admission; an aggressive early management is therefore required for these patients. Despite this, appropriate management of BP in acute ICH is still controversial, due to the complex issues involved, and the heterogeneous results obtained in clinical trials. This article will review the available evidence supporting acute BP reduction in acute ICH.

Suspected brain metastasis from lung cancer mimicking intracerebral hemorrhage: A case report.

RATIONALE: Hemorrhage rarely occurs in a solitary brain metastasis from lung carcinoma. PATIENT CONCERNS: We report on a 54-year-old man who presented with a severe headache for 4 days. DIAGNOSES: Based on computed tomography and magnetic resonance imaging enhancement, the patient was diagnosed with a suspected hemorrhagic brain metastasis from lung carcinoma. INTERVENTIONS: The patient's family rejected a pathological examination. OUTCOMES: The patient's family requested discharge after diagnosis. LESSONS: The present case emphasizes the need to consider hemorrhagic metastasis as a differential diagnosis in patients presenting with solitary intracerebral hemorrhage whose location is uncommon, especially when the poor general state of the patient cannot be attributed to hypertensive intracerebral hemorrhage.

Decompressive craniectomy for intracerebral haematoma: the influence of additional haematoma evacuation.

Intracerebral haemorrhage (ICH) may lead to intractable elevation of intracranial pressure (ICP), which may lead to decompressive craniectomy (DC). In this setting, surgical evacuation of ICH is controversially discussed. We therefore analysed radiological and clinical parameters to investigate the influence of additional haematoma evacuation to DC in patients with ICH. Forty-four patients suffering from spontaneous, hypertensive ICH between August 2007 and February 2016 underwent DC with and without ICH evacuation at the author's institution. Patients were stratified into two groups (DC without ICH evacuation versus DC with ICH evacuation). Patient characteristics, clinical and radiological findings were assessed and retrospectively analysed. Fifteen (34%) patients underwent DC with additional ICH evacuation and 29 (66%) underwent DC without ICH evacuation. Mean ICH volume was 60 ± 38 ml with no significant difference between both groups (p = 0.8). Midline shift (MLS) reduction after DC did not significantly differ between both groups (p = 0.4). Overall, 13 patients (30%) achieved a favourable outcome. DC can be performed in cases of spontaneous supratentorial ICH and pathological elevated ICP despite best medical treatment. However, additional ICH evacuation does not seem to be beneficial according to the present study and may therefore be omitted.

Cortical blindness as a rare presentation of hemorrhagic cerebral hyperperfusion syndrome following vertebral angioplasty.

Cerebral hyperperfusion syndrome (CHS) is a well-documented complication after carotid endarterectomy or stenting. In contrast, CHS following vertebral revascularization is extremely rare. Here we present a case of a 77-year-old man with high-grade vertebral stenosis who subsequently underwent balloon angioplasty, complicated by hemorrhagic CHS manifesting as cortical blindness, although strict postoperative blood pressure control was administered. To our knowledge, cortical blindness as a presentation of hemorrhagic CHS has not previously been reported. This study highlights the fact that identifying high-risk patients, as well as making an individual therapeutic plan, is important prior to revascularization. Further studies are needed to elucidate the exact mechanism of this condition and thereby prevent it.

Comparison of endoscopic evacuation, stereotactic aspiration and craniotomy for the treatment of supratentorial hypertensive intracerebral haemorrhage: study protocol for a randomised controlled trial.

BACKGROUND: Hypertensive intracerebral haemorrhage (HICH) is the most common form of haemorrhagic stroke with the highest morbidity and mortality of all stroke types. The choice of surgical or conservative treatment for patients with HICH remains controversial. In recent years, minimally invasive surgeries, such as endoscopic evacuation and stereotactic aspiration, have been attempted for haematoma removal and offer promise. However, research evidence on the benefits of endoscopic evacuation or stereotactic aspiration is still insufficient. METHODS/DESIGN: A multicentre, randomised controlled trial will be conducted to compare the efficacy of endoscopic evacuation, stereotactic aspiration and craniotomy in the treatment of supratentorial HICH. About 1350 eligible patients from 10 neurosurgical centres will be randomly assigned to an endoscopic group, a stereotactic group and a craniotomy group at a 1:1:1 ratio. Randomisation is undertaken using a 24-h randomisation service accessed by telephone or the Internet. All patients will receive the corresponding surgery based on their grouping. They will be followed-up at 1, 3 and 6 months after surgery. The primary outcome is the modified Rankin Scale at 6-month follow-up. Secondary outcomes include: haematoma clearance rate; Glasgow Coma Scale 7 days after surgery; rebleeding rate; intracranial infection rate; hospitalisation time; mortality at 1 month and 3 months after surgery; the Barthel Index and the WHO quality of life at 3 months and 6 months after surgery. DISCUSSION: The trial aims to investigate whether endoscopic evacuation and stereotactic aspiration could improve the outcome of supratentorial HICH compared with craniotomy. The trial will help to determine the best surgical method for the treatment of supratentorial HICH. TRIAL REGISTRATION: ClinicalTrials.gov, ID: NCT02811614 . Registered on 20 June 2016.

Efficacy of lumbar cistern drainage combined with intrathecal antibiotherapy for the treatment of ventriculo-subarachnoid infections following surgery for hypertensive intracerebral hemorrhage.

OBJECTIVE: The aim of this study was to investigate the efficacy of lumbar cistern drainage combined with intrathecal injection of antibiotics (LCD-ITI) in treating postoperative intracranial infections of hypertensive intracerebral hemorrhage (pHIH-ICI). METHODS: Sixty pHIH-ICI patients were randomly divided into the control group and the treatment group, with 30 patients in each group. Conventional treatment was performed in the control group, while LCD-ITI was performed in the treatment group. The clinical outcomes, Glasgow Outcome Score (GOS), activities of daily living (ADL) scores, incidence rates of hydrocephalus and other indicators were compared. RESULTS: The improvement time of clinical symptoms, infection control time and hydrocephalus incidence of the treatment group were significantly lower than the control group (P<0.05). Also the infection control rate, GOS score and ADL score of the treatment group were significantly higher or better than the control group (P<0.05). CONCLUSION: LCD-ITI could improve clinical treatment and prognosis of pHIH-ICI patients.

The tomography usefulness in the precision diagnostic and the follow-up of the cases were evidenced(EU)

Assessment of Risk of Aneurysmal Rupture in Patients with Normotensives, Controlled Hypertension, and Uncontrolled Hypertension.

BACKGROUND: The prevalence of hypertension in patients with intracranial aneurysms has been an increased concern, but it is not well understood if uncontrolled hypertension has impact on aneurysmal rupture. The aim of this study was to determine whether the risk of aneurysmal rupture is higher in uncontrolled hypertensive cohorts than in controlled hypertensive cohorts and normotensive cohorts. METHODS: We retrospectively analyzed the records and angiographies of 456 patients with aneurysms who were treated at our center between June 2013 and June 2014. Three groups of patients were included in the study following the ESH-ESC (European Society of Hypertension-European Society of Cardiology) 2013 guidelines: normotensive group (n = 229), controlled hypertension group (n = 127), and uncontrolled hypertension group (n = 100). Paired comparisons of these 3 groups were analyzed with the Nemenyi test. Multivariate logistic regression analysis was used to exclude the impact of possible confounding factors. RESULTS: The results of the univariate analysis showed that hypertension, smoking, and size of the aneurysms were significantly associated with intracranial aneurysmal rupture (P < .05). The multivariate logistic regression analysis containing clinical and aneurysmal characteristics showed that uncontrolled hypertension, smoking, and aneurysm size were statistically significant predictors of intracranial aneurysmal rupture (P < .05). The paired comparisons of 3 groups showed that the risk of rupture of intracranial aneurysms in the uncontrolled hypertension group was significantly greater than that in the normotensive group (P < .05) and in the controlled hypertension group (P < .05). CONCLUSIONS: Uncontrolled hypertension is associated with increased risk of rupture of intracranial aneurysms. Given that aneurysmal rupture is a potentially fatal-but preventable-complication, these findings are of clinical relevance.

Continuing versus Stopping Prestroke Antihypertensive Therapy in Acute Intracerebral Hemorrhage: A Subgroup Analysis of the Efficacy of Nitric Oxide in Stroke Trial.

BACKGROUND AND PURPOSE: More than 50% of patients with acute intracerebral hemorrhage (ICH) are taking antihypertensive drugs before ictus. Although antihypertensive therapy should be given long term for secondary prevention, whether to continue or stop such treatment during the acute phase of ICH remains unclear, a question that was addressed in the Efficacy of Nitric Oxide in Stroke (ENOS) trial. METHODS: ENOS was an international multicenter, prospective, randomized, blinded endpoint trial. Among 629 patients with ICH and systolic blood pressure between 140 and 220 mmHg, 246 patients who were taking antihypertensive drugs were assigned to continue (n = 119) or to stop (n = 127) taking drugs temporarily for 7 days. The primary outcome was the modified Rankin Score at 90 days. Secondary outcomes included death, length of stay in hospital, discharge destination, activities of daily living, mood, cognition, and quality of life. RESULTS: Blood pressure level (baseline 171/92 mmHg) fell in both groups but was significantly lower at 7 days in those patients assigned to continue antihypertensive drugs (difference 9.4/3.5 mmHg, P < .01). At 90 days, the primary outcome did not differ between the groups; the adjusted common odds ratio (OR) for worse outcome with continue versus stop drugs was .92 (95% confidence interval, .45-1.89; P = .83). There was no difference between the treatment groups for any secondary outcome measure, or rates of death or serious adverse events. CONCLUSIONS: Among patients with acute ICH, immediate continuation of antihypertensive drugs during the first week did not reduce death or major disability in comparison to stopping treatment temporarily.

[Blood pressure treatment in the acute stage of stroke]. / Blutdruckbehandlung im Akutstadium des Schlaganfalls.

The results of previous studies on blood pressure in acute stroke therapy allow a few generally valid therapeutic recommendations. Efforts should be made to achieve a constant blood pressure level without major fluctuations. An antihypertensive therapy in the acute stage of stroke should be initiated only at highly elevated values. High blood pressure levels can be tolerated in patients with ischemic stroke unless thrombolytic comes into consideration. Should this be desired, the blood pressure must be quickly lowered to a target range of at least < 180 mmHg. In the case of intracerebral hemorrhage a blood pressure reduction appears to be beneficial. The ESO recommends a reduction to < 140 mmHg systolic within one hour, according to recommendations of the ESH and the EUSI but not more than 20 %.

Differences Between Vascular Structural Abnormality and Hypertensive Intracerebral Hemorrhage.

BACKGROUND: How the clinical characteristics and prognosis of various types of vascular structural abnormality-related intracerebral hemorrhage (ICH) differ from those of hypertensive ICH is poorly understood. This lack of understanding poses a problem for differential diagnosis and prognosis. METHODS: Patients diagnosed with ICH between January 2012 and February 2014 at 50 tertiary and secondary hospitals in China were enrolled into this prospective cohort study. Patients were classified as having vascular structural abnormality-related ICH or hypertensive ICH, and data on the demographics and clinical characteristics of each group were compared. Multivariate logistic regression was used to explore associations while controlling for other risk factors for good outcome and mortality. RESULTS: Data for 281 patients showed that vascular structural abnormality-related ICH usually occurred in lobar areas and affected patients who were younger and had higher Glasgow Coma Scale (GCS) scores than those with hypertensive ICH. Mortality and good outcome at 3 months after ICH were significantly better among patients with vascular structural abnormality-related ICH (3.4% and 77.2%) than among patients with hypertensive ICH (15.2% and 49.9%, both P < .001). Multivariate logistic regression identified the following independent predictors of mortality: lower GCS score, old age, presence of intraventricular hemorrhage, larger hematoma volume, and surgery treatment. The regression also identified several independent predictors of good outcome at 3 months: ICH etiology due to vascular structural abnormality, higher GCS score, younger age, and smaller hematoma volume. CONCLUSIONS: Patients with vascular structural abnormality-related ICH are more likely to experience better clinical outcomes than those with hypertensive ICH. GCS score, age, hematoma volume, and ICH etiology are independent predictors of ICH outcome.

Performance characteristics of methods for quantifying spontaneous intracerebral haemorrhage: data from the Efficacy of Nitric Oxide in Stroke (ENOS) trial.

BACKGROUND: Poor prognosis after intracerebral haemorrhage (ICH) is related to haemorrhage characteristics. Along with developing therapeutic interventions, we sought to understand the performance of haemorrhage descriptors in large clinical trials. METHODS: Clinical and neuroimaging data were obtained for 548 participants with ICH from the Efficacy of Nitric Oxide in Stroke (ENOS) trial. Independent observers performed visual categorisation of the largest diameter, measured volume using ABC/2, modified ABC/2, semiautomated segmentation (SAS), fully automatic measurement methods; shape, density and intraventricular haemorrhage were also assessed. Intraobserver and interobserver reliability were determined for these measures. RESULTS: ICH volume was significantly different among standard ABC/2, modified ABC/2 and SAS: (mean) 12.8 (SD 16.3), 8.9 (9.2), 12.8 (13.1) cm(3), respectively (p<0.0001). There was excellent agreement for haemorrhage volume (n=193): ABC/2 intraobserver intraclass correlation coefficient (ICC) 0.96-0.97, interobserver ICC 0.88; modified ABC/2 intraobserver ICC 0.95-0.97, interobserver ICC 0.91; SAS intraobserver ICC 0.95-0.99, interobserver ICC 0.93; largest diameter: (visual) interadjudicator ICC 0.82, (visual vs measured) adjudicator vs observer ICC 0.71; shape intraobserver ICC 0.88 interobserver ICC 0.75; density intraobserver ICC 0.86, interobserver ICC 0.73. Graeb score (mean 3.53) and modified Graeb (5.22) scores were highly correlated. Using modified ABC/2, ICH volume was underestimated in regular (by 2.2-2.5 cm(3), p<0.0001) and irregular-shaped haemorrhages (by 4.8-4.9 cm(3), p<0.0001). Fully automated measurement of haemorrhage volume was possible in only 5% of cases. CONCLUSIONS: Formal measurement of haemorrhage characteristics and visual estimates are reproducible. The standard ABC/2 method is superior to the modified ABC/2 method for quantifying ICH volume. CLINICAL TRIAL REGISTRATION: ISRCTN9941422.

Associations between biomarkers of renal function with cerebral microbleeds in hypertensive patients.

BACKGROUND: Cerebral microbleeds (CMBs) have been observed in the elderly and have been regarded as a manifestation of small vessel disease (SVD). Cerebral and glomerular SVD may have a common source of pathogenesis because these organs are closely connected through anatomic and hemodynamic similarities. The purpose of this study was to clarify the associations between kidney biomarker levels and CMBs in hypertensive patients. METHODS: The presence and number of CMBs were assessed on susceptibility-weighted imaging. We calculated the urinary albumin/creatinine ratio (UACR) from morning spot urine and the estimated glomerular filtration rate (eGFR) in serum samples. Serum cystatin C (CysC) was measured with an automated particle-enhanced turbidimetric immunoassay. RESULTS: UACR and CysC levels were higher in the patients with CMBs than those without, and the eGFR was lower in the patients with CMBs than those without. A logistic regression analysis indicates that eGFR and UACR were independently associated with the prevalence of deep or infratentorial CMBs. The odds ratio (OR) (95% confidence interval (CI)) of eGFR and UACR was 1.95 (1.37-3.27) and 2.25 (1.66-4.46), respectively. CysC was independently associated with CMBs in both deep or infratentorial and lobar locations. The ORs (95% CI) were 2.59 (1.57-6.22) and 1.57 (1.15-4.85), respectively. Furthermore, CysC exhibited fair diagnostic value for CMBs, with an area under the curve of 0.80. CONCLUSIONS: Kidney biomarker levels are associated with the presence of CMB in hypertensive patients without a history of transient ischemic attack (TIA) or stroke, independent of conventional risk factors, and CysC was a better marker for CMBs than eGFR and UACR.
