ABSTRACT: Objective
To compare rates of intracerebral hemorrhage (ICH) in HIV-infected and uninfected individuals in a large clinical care cohort and to assess risk factors associated with ICH.Methods
We identified incident ICH in HIV-infected and uninfected control cohorts from the Partners Health Care system using ICD-9-CM codes. We constructed Cox proportional hazards models to estimate adjusted hazard ratios for HIV infection and other predictors of ICH.Results
The incidence rate of ICH was 2.29 per 1,000 person-years in HIV-infected individuals compared with 1.23 per 1,000 person-years in uninfected individuals, with an unadjusted incidence rate ratio of 1.85 (95% confidence interval 1.37-2.47, p < 0.001). In a multivariable model, HIV infection was independently associated with a higher hazard of ICH, although its effect diminished with increasing age. Female sex was associated with a lower hazard of ICH in the uninfected cohort but not in the HIV cohort. CD4 count <200 × 10(6) cells/L and anticoagulant use were predictive of ICH.Conclusions
HIV infection conferred an increased adjusted hazard of ICH, which was more pronounced in young patients and in women.

Project description:Intracerebral hemorrhage remains a challenging worldwide clinical problem with no proven treatments. In the acute phase of the illness, there has been some controversy regarding the appropriate management of elevated blood pressure. Recently published and ongoing clinical trials are beginning to shed some light on appropriate blood pressure management in acute intracerebral hemorrhage. This brief review focuses on these trials. In the next few years, it is hoped that clinical uncertainty regarding this issue will be obviated after completion of these trials.

Project description:ObjectiveObservational studies point to an inverse correlation between low-density lipoprotein (LDL) cholesterol levels and risk of intracerebral hemorrhage (ICH), but it remains unclear whether this association is causal. We tested the hypothesis that genetically elevated LDL is associated with reduced risk of ICH.MethodsWe constructed one polygenic risk score (PRS) per lipid trait (total cholesterol, LDL, high-density lipoprotein [HDL], and triglycerides) using independent genomewide significant single nucleotide polymorphisms (SNPs) for each trait. We used data from 316,428 individuals enrolled in the UK Biobank to estimate the effect of each PRS on its corresponding trait, and data from 1,286 ICH cases and 1,261 matched controls to estimate the effect of each PRS on ICH risk. We used these estimates to conduct Mendelian Randomization (MR) analyses.ResultsWe identified 410, 339, 393, and 317 lipid-related SNPs for total cholesterol, LDL, HDL, and triglycerides, respectively. All four PRSs were strongly associated with their corresponding trait (all p < 1.00 × 10-100 ). While one SD increase in the PRSs for total cholesterol (odds ratio [OR] = 0.92; 95% confidence interval [CI] = 0.85-0.99; p = 0.03) and LDL cholesterol (OR = 0.88; 95% CI = 0.81-0.95; p = 0.002) were inversely associated with ICH risk, no significant associations were found for HDL and triglycerides (both p > 0.05). MR analyses indicated that 1mmol/L (38.67mg/dL) increase of genetically instrumented total and LDL cholesterol were associated with 23% (OR = 0.77; 95% CI = 0.65-0.98; p = 0.03) and 41% lower risks of ICH (OR = 0.59; 95% CI = 0.42-0.82; p = 0.002), respectively.InterpretationGenetically elevated LDL levels were associated with lower risk of ICH, providing support for a potential causal role of LDL cholesterol in ICH.

Project description:Opinion statementIntracerebral hemorrhage is a medical emergency. It is the most deadly and disabling form of stroke, and no individual therapy has been demonstrated to improve outcome. However, it appears that aggressive medical care in general, and management by neuroscience specialists in particular, offers substantial benefit. Therefore, providing the best supportive care based on currently available evidence may well improve outcomes. Airway management and management of blood pressure aimed at maximizing cerebral perfusion while minimizing ongoing bleeding, as well as rapid reversal of anticoagulation, are likely to be important in the early phase. Additionally, efforts should be undertaken to provide careful glucose management and temperature management and to maximize cerebral perfusion pressure. Selected patients are likely to benefit from external ventricular drainage or even hematoma evacuation. Except in rare circumstances, most patients should be managed in a neuroscience intensive care unit during the acute phase. Some patients appear to have no reasonable likelihood of recovery and can be considered for limitations of care such as Do Not Resuscitate orders or Comfort Measures Only orders. However, it can be difficult to accurately predict long-term outcome in the acute phase; formal prognostic tools should be used to offer information to patients and their families. After the hemorrhage has stabilized, efforts to minimize complications include thromboembolism prophylaxis, physical therapy, and acute rehabilitation.

Project description:Background and purposePatient selection in clinical trials on intracerebral hemorrhage (ICH) affects overall applicability of results. We estimated eligibility for completed, ongoing, and planned clinical trials in an unselected cohort of patients with ICH.MethodsLarge clinical ICH trials were identified using trial registration databases. Each trial's inclusion criteria were applied to a consecutive group of patients with ICH from the prospective hospital-based Lund Stroke Register. Survival status was obtained from the National Census Office and 90-day poor functional outcome (modified Rankin Scale ≥4) from the Swedish Stroke Register or medical files.ResultsAmong 253 patients with ICH, estimated eligibility proportions ranged between 2% and 36% for the 11 identified clinical trials. Patients not eligible for any trial (n=96) had more intraventricular hemorrhage, lower baseline level of consciousness, higher rates of cerebellar ICH, and lower rates of lobar ICH (P≤0.001). Thirty-day case fatality for noneligible patients was 54% versus 18% among patients eligible in ≥1 trial (95% confidence interval, 44%-64% versus 13%-25%; P<0.001). Noneligible ICH patients more frequently had poor functional outcome (75% versus 48%; 95% confidence interval, 65%-83% versus 40%-56%; P<0.001).ConclusionsThere is large variation in proportions of patients with ICH eligible for inclusion in clinical trials and over a third of patients with ICH are not eligible for any trial.

Project description:Intracerebral hemorrhage (ICH) is a life-threatening condition associated with significant morbidity and mortality. Understanding the molecular mechanisms underlying ICH and its severe form is crucial for developing effective therapeutic strategies. This study investigates transcriptomic alterations in rodent models of ICH and severe intracerebral hemorrhage to shed light on the genetic pathways involved in hemorrhagic brain injury. We performed principal component analysis, revealing distinct principal component segments of normal rats compared to intracerebral hemorrhage and severe intracerebral hemorrhage rats. We further employed heatmaps and volcano plots to identify differentially expressed genes and utilized bar plots and KEGG pathway analysis to elucidate the different molecular pathways involved. Using comprehensive RNA sequencing and bioinformatics analyses, we identified a multitude of differentially expressed genes in both the ICH and severe ICH models. Our results revealed 5679 common genes among the normal, intracerebral hemorrhage, and severe intracerebral hemorrhage groups in the upregulated genes group, and 1196 common genes in the downregulated genes. A volcano plot comparing the groups further highlighted common genes, including PDPN, TIMP1, SERPINE1, TUBB6, and CD44. These findings underscore the complex interplay of genes involved in inflammation, oxidative stress, and neuronal damage. Furthermore, pathway enrichment analysis uncovered key signaling pathways, including the TNF signaling pathway, protein processing in the endoplasmic reticulum, MAPK signaling pathway, and Fc gamma R-mediated phagocytosis, implicated in the pathogenesis of ICH.

Project description:BackgroundAlthough cardiac troponin has been well established as diagnostic and prognostic makers for acute coronary heart disease, the prognostic value of elevated cardiac troponin in patients with intracerebral hemorrhage (ICH) was inconsistent and not systematically evaluated.HypothesisWe proposed the hypothesis that the practical utility of cardiac troponin levels for prediction of mortality and poor outcome in ICH patients.MethodsA total of 1004 patients with ICH were retrospectively reviewed and qualified for further analysis from June 2012 to December 2015. The patients were divided into different groups based on measurements of cardiac troponin I (cTnI) at the time of admission and the following day. Multivariate Cox proportional hazards analysis were performed to determine the independent prognostic value of the cTnI for patients in-hospital mortality and poor outcomes, the receiver operator characteristic (ROC) analysis was performed to assess the predictive value of cTnI, ICH score, and combination of them.ResultsSerum cTnI level was an independent predictor in-hospital mortality (positive vs negative, HR (hazard ratios) = 3.44, 95% CI (confidence interval) 1.66-7.13, P <?.001) and poor outcomes in patients with ICH (positive vs negative, HR = 6.69, 95% CI 4.25-10.52, P <?.001). Addition of cTnI to ICH score significantly improved the prognostic discrimination for both in-hospital mortality and poor outcomes.ConclusionSerum cTnI levels may be valuable as predictor for in hospital mortality and poor outcomes and may be useful in the risk stratification of ICH during hospitalization.

Project description:Objective: Early enteral nutrition (EEN) represents the current standard of care for patients treated in general intensive care units (ICU). Specific nutritional recommendations for patients receiving dedicated neurocritical care are not established. This study investigated associations of EEN with clinical outcomes for patients suffering from intracerebral hemorrhage treated at a neurological ICU (NICU). Methods: This retrospective cohort study included patients admitted to the NICU with atraumatic ICH over a 4-year period. Nutritional data, demographic, clinical, radiological, and laboratory characteristics were assessed. EEN was defined as any enteral nutrition within 48 hours after admission. Comparisons were undertaken for patients with EEN vs. those without, further propensity score (PS) matching (caliper 0.2; one: many) was used to account for baseline imbalances. Primary outcome was the modified Rankin Scale (0-3 = favorable, 4-6 = unfavorable) at 12 months, secondary outcomes comprised perihemorrhagic edema (PHE) volume, infectious complications during the hospital stay, and mRS at 3 months, as well as mortality rates at 3 and 12 months. Results: Of 166 ICH-patients treated at the NICU, 51 (30.7%) patients received EEN, and 115 (69.3%) patients received no EEN (nEEN). After propensity score matching, calories delivered from enteral nutrition (EEN 161.4 [106.4-192.3] kcal/day vs. nEEN 0.0 [0.0-0.0], P < 0.001) and the total calories (EEN 190.0 [126.0-357.0] kcal/day vs. nEEN 33.6 [0.0-190.0] kcal/day, P < 0.001) were significantly different during the first 48 h admitted in NICU. Functional outcome at 12 months (mRS 4-6, EEN 33/43 [76.7%] vs. nEEN, 49/64 [76. 6%]; P = 1.00) was similar in the two groups. There were neither differences in mRS at 3 months, nor in mortality rates at 3 and 12 months between the two groups. EEN did not affect incidence of infective complications or gastrointestinal adverse events during the hospital stay; however, EEN was associated with significantly less extent of PHE evolution [maximum absolute PHE (OR 0.822, 95% CI 0.706-0.957, P = 0.012); maximum relative PHE (OR 0.784, 95% CI 0.646-0.952, P = 0.014)]. Conclusion: In our study, EEN was associated with reduced PHE in ICH-patients treated at a NICU. However, this observation did not translate into improved survival or functional outcome at 3 and 12 months.

Project description:Background and purposeVenous thromboembolism (VTE) is a life-threatening complication of stroke. We evaluated nationwide rates and risk factors for hospital readmissions with VTE after an intracerebral hemorrhage (ICH) or acute ischemic stroke (AIS) hospitalization.MethodsUsing the Healthcare Cost and Utilization Project (HCUP) Nationwide Readmission Database, we included patients with a principal discharge diagnosis of ICH or AIS from 2016 to 2019. Patients who had VTE diagnosis or history of VTE during the index admission were excluded. We performed Cox regression models to determine factors associated with VTE readmission, compared rates between AIS and ICH and developed post-stroke VTE risk score. We estimated VTE readmission rates per day over a 90-day time window post-discharge using linear splines.ResultsOf the total 1,459,865 patients with stroke, readmission with VTE as the principal diagnosis within 90 days occurred in 0.26% (3,407/1,330,584) AIS and 0.65% (843/129,281) ICH patients. The rate of VTE readmission decreased within first 4-6 weeks (P<0.001). In AIS, cancer, obesity, higher National Institutes of Health Stroke Scale (NIHSS) score, longer hospital stay, home or rehabilitation disposition, and absence of atrial fibrillation were associated with VTE readmission. In ICH, longer hospital stay and rehabilitation disposition were associated with VTE readmission. The VTE rate was higher in ICH compared to AIS (adjusted hazard ratio 2.86, 95% confidence interval 1.93-4.25, P<0.001).ConclusionsAfter stroke, VTE readmission risk is highest within the first 4-6 weeks and nearly three-fold higher after ICH vs. AIS. VTE risk is linked to decreased mobility and hypercoagulability. Studies are needed to test short-term VTE prophylaxis beyond hospitalization in high-risk patients.

Project description:ObjectiveTo compare comorbidities and use of surgery and palliative care between men and women with intracerebral hemorrhage (ICH).MethodsThe Ethnic/Racial Variations of Intracerebral Hemorrhage (ERICH) study is a prospective, multicenter, case-control study of ICH risk factors and outcomes. We compared comorbidities, treatments, and use of do-not-resuscitate (DNR) orders in men vs women. Multivariate analysis was used to assess the likelihood of ICH surgery and palliative care after adjustment for variables that were p < 0.1 in univariate analyses and backward elimination to retain those that were significant (p < 0.05).ResultsWomen were older on average (65.0 vs 59.9, p < 0.0001), and higher proportions of women had previous stroke (24.1% vs 19.3%, p = 0.002), had dementia (6.1% vs 3.4%, p = 0.0007), lived alone (23.1% vs 18.0%, p = 0.0005), and took anticoagulants (12.8% vs 10.1% p = 0.02), compared with men. Men had higher rates of alcohol and cocaine use. After adjusting for age, hematoma volume, and ICH location, there was no difference in rates of surgical treatment by sex (odds ratio [OR] 0.93 for men vs women, 95% confidence interval [CI] 0.68-1.28, p = 0.67), and there was no difference in DNR/comfort care decisions after adjustment for ICH score, prior stroke, and dementia (OR 0.96, CI 0.77-1.22, p = 0.76).ConclusionsAfter ICH, women do not receive less aggressive care than men after controlling for the substantial comorbidity differences. Future studies on sex bias should include the presence of comorbidities, prestroke disability, and other factors that may influence management.

Project description:ObjectiveWe tested the hypothesis that surveillance neuroimaging and neurologic examinations identified changes requiring emergent surgical interventions in patients with intracerebral hemorrhage (ICH).MethodsPatients with primary ICH were enrolled into a prospective registry between December 2006 and July 2012. Patients were managed in a neuroscience intensive care unit with a protocol that included serial neuroimaging at 6, 24, and 48 hours, and hourly neurologic examinations using the Glasgow Coma Scale and NIH Stroke Scale. We evaluated all cases of craniotomy and ventriculostomy to determine whether the procedure was part of the initial management plan or occurred subsequently. For those that occurred subsequently, we determined whether worsening on neurologic examination or worsened neuroimaging findings initiated the process leading to intervention.ResultsThere were 88 surgical interventions in 84 (35%) of the 239 patients studied, including ventriculostomy in 52 (59%), craniotomy in 21 (24%), and both in 11 (13%). Of the 88 interventions, 24 (27%) occurred subsequently and distinctly from initial management, a median of 15.9 hours (8.9-27.0 hours) after symptom onset. Thirteen (54%) were instigated by findings on neurologic examination and 11 (46%) by neuroimaging. Demographics, severity of hemorrhage, and hemorrhage location were not associated with delayed intervention.ConclusionsMore than 25% of surgical interventions performed after ICH were prompted by delayed imaging or clinical findings. Serial neurologic examinations and neuroimaging are important and effective surveillance techniques for monitoring patients with ICH.
