Abstract
Background: There has been intensive research into enhancing the effects of reperfusion therapy to mitigate hemorrhagic transformation (HT) in stroke patients. Using neuroprotective agents alongside intravenous thrombolysis (IVT) appears a promising approach. Cerebrolysin is one of the candidates since it consists of neuropeptides mimicking the action of neurotrophic factors on brain protection and repair. Objectives: We looked at treatment effects of Cerebrolysin as an early add-on to IVT in stroke patients with varying HT risk. Methods: It was post hoc analysis of the CEREHETIS trial (ISRCTN87656744). Patients with middle cerebral artery infarction (n = 238) were selected from the intention-to-treat population. To stratify participants according to their HT risk, the DRAGON, SEDAN and HTI scores were computed for each eligible subject using on-admission data. The study endpoints were any and symptomatic HT, and functional outcome measured with the modified Rankin Scale (mRS) on day 90. Favorable functional outcome (FFO) was defined as an mRS ≤2. The performance of each stratification tool was estimated with regression approaches. Heterogeneous treatment effect analysis was conducted using techniques of meta-analysis and the matching-smoothing method. Results: The HTI score outperformed other tools in terms of HT risk stratification. Heterogeneity of Cerebrolysin treatment effects was moderate (I2, 35.8%-56.7%; H2, 1.56-2.31) and mild (I2, 10.9%; H2, 1.12) for symptomatic and any HT, respectively. A significant positive impact of Cerebrolysin on HT and functional outcome was observed in the moderate (HTI = 1) and high (HTI ≥2) HT risk patients, but it was neutral in those with the low (HTI = 0) risk. In particular, there was a steady decline in the rate of symptomatic (HTI = 0 vs. HTI = 4: by 4.3%, p = 0.077 vs. 21.1%, p < 0.001) and any HT (HTI = 0 vs. HTI = 4: by 1.2%, p = 0.737 vs. 32.7%, p < 0.001). Likewise, an mRS score reduction (HTI = 0 vs. HTI = 4: by 1.8%, p = 0.903 vs. 126%, p < 0.001) with a reciprocal increase of the fraction of FFO patients (HTI = 0 vs. HTI = 4: by 1.2% p = 0.757 vs. 35.5%, p < 0.001) was found. Conclusion: Clinically meaningful heterogeneity of Cerebrolysin treatment effects on HT and functional outcome was established in stroke patients. The beneficial effects were significant in those whose estimated on-admission HT risk was either moderate or high.

Abstract
OBJECTIVE The study goal was the assessment of heterogeneous treatment effects of Cerebrolysin as an early add-on to reperfusion therapy in stroke patients with varying risk of hemorrhagic transformation (HT). MATERIAL AND METHODS It was post hoc analysis of the CEREHETIS trial (ISRCTN87656744). Patients with middle cerebral artery infarction (n=238) were stratified by HT risk with the HTI score. The study outcomes were symptomatic and any HT, and functional outcome measured with the modified Rankin Scale (mRS) on day 90. Favorable outcome was defined as an mRS score of ≤2. Heterogeneous treatment effect analysis was performed using techniques of meta-analysis and the matching-smoothing method. RESULTS Heterogeneity of Cerebrolysin treatment effects was moderate (I2=36.98-69.3%, H2=1.59-3.26) and mild (I2=18.33-32.39%, H2=1.22-1.48) for symptomatic and any HT, respectively. A positive impact of the Cerebrolysin treatment on HT and functional outcome was observed in patients with moderate (HTI=1) and high (HTI≥2) HT risk. However, the effect was neutral in those with low risk (HTI=0). In high HT risk patients, there was a steady decline in the rate of symptomatic (HTI=0 vs. HTI≥2: by 3.8%, p=0.120 vs. 14.3%, p<0.001) and any HT (HTI=0 vs. HTI≥2: by 0.6%, p=0.864 vs. 19.5%, p<0.001). Likewise, Cerebrolysin treatment resulted in an overall decrease in the mRS scores (HTI=0 vs. HTI≥2: by 2.1%, p=0.893 vs. 63%, p<0.001) with a reciprocal increase of the fraction with favorable outcome (HTI=0 vs. HTI≥2: by 2% p=0.634 vs. 19.2%, p<0.001). CONCLUSION Clinically meaningful heterogeneity of Cerebrolysin treatment effects on HT and functional outcome was established in stroke patients. The Cerebrolysin positive impact was significant in those whose estimated on-admission HT risk was either moderate or high.

Abstract
BACKGROUND Cerebrolysin could mitigate reperfusion injury and hemorrhagic transformation (HT) in animal models of acute ischemic stroke. METHODS This was a prospective, randomized, open-label, parallel-group with active control, multicenter pilot study. Cerebrolysin (30 mL/day over 14 days) was administered concurrently with alteplase (0.9 mg/kg) in 126 patients, whereas 215 control patients received alteplase alone. The primary outcomes were the rate of any and symptomatic HT assessed from day 0 to 14. The secondary endpoints were drug safety and functional outcome measured with the National Institutes of Health Stroke Scale (NIHSS) on day 1 and 14, and the modified Rankin scale (mRS) on day 90. Advanced brain imaging analysis was applied on day 1 and 14 as a marker for in vivo pharmacology of Cerebrolysin. RESULTS Cerebrolysin treatment resulted in a substantial decrease of the symptomatic HT rate with an odds ratio (OR) of 0.248 (95% CI: 0.072-0.851; p = 0.019). No serious adverse events attributed to Cerebrolysin occurred. On day 14, the Cerebrolysin arm showed a significant decrease in the NIHSS score (p = 0.045). However, no difference in the mRS score was observed on day 90. A substantial improvement in the advanced brain imaging parameters of the infarcted area was evident in the Cerebrolysin group on day 14. CONCLUSIONS Early add-on of Cerebrolysin to reperfusion therapy was safe and significantly decreased the rate of symptomatic HT as well as early neurological deficit. No effect on day 90 functional outcome was detected. Improvements in the imaging metrics support the neuroprotective and blood-brain barrier stabilizing activity of Cerebrolysin.

Abstract
Despite the significant shift in global attention away from the pandemic, the problem of a new coronavirus infection remains important in the medical community. Almost 3 years after the start of the COVID-19 pandemic the issues of rehabilitation and management of delayed manifestations and sequelae of the disease are especially important. According to numerous available data, the new coronavirus infection is characterized by multiorgan lesions. Respiratory dysfunction, clotting disorders, myocardial dysfunction and various arrhythmias, acute coronary syndrome, acute renal failure, GI disorders, hepatocellular damage, hyperglycemia and ketosis, dermatological complications, ophthalmological symptoms and neurological disorders may be found. Significant prevalence of the latter in the post-coronavirus period necessitated this International Expert Forum to develop unified approaches to the management of patients with neurological complications and sequelae of new coronavirus infection based on practical experience and considering the scientific information available on COVID-19. The expert council developed a resolution formulating the tactics for the management of patients with neurological manifestations of COVID-19.

Abstract
OBJECTIVE The study aimed to assess effects of the simultaneous use of Cerebrolysin and intravenous thrombolysis (Alteplase) on hemorrhagic transformation (HT) and functional outcome as well as to analyze the treatment safety in acute stroke patients. MATERIAL AND METHODS It was a prospective, randomized, open-label, multicenter, parallel-group, active-controlled pilot study (Trial Registration Number: ISRCTN87656744, https://doi.org/10.1186/ISRCTN87656744, Trial registration date: 16/02/2021). The intervention group (n=126) was treated with Cerebrolysin infusion (30 mL) started simultaneously with Alteplase (0.9 mg/kg) via a separate IV line. The Cerebrolysin treatment continued for 14 consecutive days with the baseline therapy along. The control group (n=215) received only Alteplase and the baseline therapy. The primary endpoints were the rate of any and symptomatic hemorrhagic transformation (HT) from admission to day 14. Secondary endpoints were treatment safety and functional outcome measured with the National Institutes of Health stroke scale (NIHSS) in 24 h and on day 14, and with the modified Rankin scale (mRS) on day 90. RESULTS Treatment with Cerebrolysin resulted in a significant reduction of the symptomatic HT rate with an odds ratio of 0.248 (95% CI: 0.072-0.851; p=0.019). No serious adverse events related to Cerebrolysin were observed. On day 14, the intervention group showed a significant reduction in the NIHSS score (p=0.045). However, no difference in the mRS score was observed on day 90, but there was a trend towards its improvement. CONCLUSION The combination of Cerebrolysin and Alteplase was safe and significantly reduced the rate of symptomatic HT and improved early neurological deficit. However, no difference in functional outcome was found on day 90, but there was a trend towards favorable functional outcome.

Unequal Efficacy of Different Infarct Location in Predicting Futile Recanalization of Patients With Acute Ischemic Stroke. Front Neurol 2022; 13:928773. [PMID: 36090854 PMCID: PMC9462394 DOI: 10.3389/fneur.2022.928773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 06/20/2022] [Indexed: 11/13/2022] Open
Abstract
Objectives Endovascular thrombectomy (EVT) is a standard treatment for acute ischemic stroke (AIS) caused by large vessel occlusion, while futile recanalization is the main factor influencing the prognosis. The present study aimed to investigate the efficacy of different infarct sites in predicting futile recanalization of patients with AIS. Methods Data were obtained from two multicenter, prospective, randomized, and controlled trials, which were concurrently conducted in China. Cases achieving a successful recanalization and with complete data of preoperative Alberta Stroke Program Early CT score (ASPECTS) and 90-day follow-up were included. The ASPECTS subregions were used to mark different infarct locations in the two cerebral hemispheres. First, the distribution of each ASPECTS subregion in the left and right hemispheres and the whole brain was analyzed, respectively. Then, the regions associated with futile recanalization were initially assessed by a univariate model. Afterward, a multivariate logistic regression model was used to identify the efficacy of different infarct sites in predicting futile recanalization. Results A total of 336 patients were included in this study with a median age of 65 years (IQR: 51–74), of whom 210 (62.50%) patients were male, and 189 (56.25%) met the definition of futile recanalization. The correlation between each ASPECTS subregion and poor outcome was different when it was restricted to a specific cerebral hemisphere. Moreover, in the left hemisphere, the internal capsule region (OR: 1.42, 95%CI: 1.13–1.95, P = 0.03) and the M3 region (OR: 2.26, 95%CI: 1.36–3.52, P = 0.001), and in the right hemisphere, M6 region (OR: 2.24, 95%CI: 1.32–3.36, P = 0.001) showed significantly higher efficacy in predicting futile recanalization. Conclusion The efficacy of different infarct locations in predicting futile recanalization is different. Different preoperative patterns of the high-efficiency regions in the infarction core or penumbra can guide the thrombectomy decision-making.
