Relationship between serum MBL,HRG,IL-23/IL-17 inflammatory axis and cerebral vasospasm and prognosis in patients with aneurysmal subarachnoid hemorrhage after interventional embolization / 国际检验医学杂志

Objective To investigate the relationship between serum mannan binding lectin(MBL),histi-dine rich glycoprotein(HRG),interleukin(IL)-23/IL-17 inflammatory axis and cerebral vasospasm(CVS)and prognosis in patients with aneurysmal subarachnoid hemorrhage(aSAH)after interventional emboliza-tion.Methods A total of 195 patients with aSAH who underwent interventional embolization treatment in the hospital from March 2019 to February 2022 were selected and were divided into no CVS group(126 cases),mild CVS group(18 cases),moderate CVS group(39 cases),and severe CVS group(12 cases)according to the occurrence and severity of CVS detected by digital subtraction angiography at the 4th postoperative day.The levels of serum MBL,HRG,IL-23 and IL-17 among the four groups before and 3 d after surgery were compared.The patients were followed up for 6 months and divided into good prognosis group(137 cases)and poor prognosis group(58 cases)according to their prognosis.Factors influencing poor prognosis in aSAH pa-tients were analyzed by multivariate Logistic regression model.The predictive value of serum MBL,HRG,IL-23,IL-17 levels and their combined application models for poor prognosis in patients with aSAH was analyzed by receiver operating characteristic(ROC)curve.Results The incidence rate of CVS after interventional em-bolization was 35.38%in 195 patients with aSAH.3 d after surgery,the serum levels of MBL,IL-23 and IL-17 in the mild,moderate,and severe CVS groups were higher than those in the no CVS group,those in the severe CVS group were higher than those in the moderate CVS group,those in the moderate CVS group were higher than those in the mild CVS group(P<0.05).The serum HRG levels in the mild,moderate,and severe CVS groups were lower than those in the non CVS group,those in the severe CVS group were lower than those in the moderate CVS group,those in the moderate CVS group were lower than those in the mild CVS group(P<0.05).3 d after surgery,the levels of serum MBL,IL-23 and IL-17 in the four groups were higher than that before surgery,while the levels of serum HRG were lower than that before surgery(P<0.05).The pro-portions of patients with aneurysm diameter≥6 mm,number of aneurysms>1,surgery time>24 h,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,and serum levels of MBL,IL-23,and IL-17 on the 3rd day after sur-gery in the good prognosis group were lower than those in the poor prognosis group,and serum HRG levels at 3 d after surgery in the good prognosis group were higher than that in the poor prognosis group(P<0.05).Multivariate Logistic regression analysis showed that aneurysm diameter≥6 mm,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,elevated serum levels of MBL,IL-23,and IL-17 and decreased HRG level at 3 d after sur-gery were independent risk factors for poor prognosis in aSAH patients(P<0.05).ROC results showed that serum levels of MBL,HRG,IL-23,and IL-17 at 3 d after surgery had certain predictive power for poor progno-sis in patients with aSAH.The predictive model with the combined application of four indicators had relatively high efficiency(the area under the curve was 0.853).Conclusion Elevated levels of MBL,IL-23,IL-17,and decreased HRG levels in aSAH patients after interventional embolization could increase the risk of CVS and are associated with poor prognosis in aSAH patients after interventional embolization.The above indicators have a certain predictive power for poor prognosis in aSAH patients.

Correlation between tomographic scales and vasospasm and delayed cerebral ischemia in aneurysmal subarachnoid hemorrhage / Correlación entre escalas tomográficas y vasoespasmo e isquemia cerebral diferida en la hemorragia subaracnoidea aneurismática

ABSTRACT Objective: To determine the prevalence of sonographic vasospasm and delayed ischemic deficit in patients with aneurysmal subarachnoid hemorrhage, to evaluate the correlation between different tomographic scales and these complications, and to study prognostic factors in this group of patients. Methods: This was a prospective study of patients admitted to the intensive care unit with a diagnosis of aneurysmal subarachnoid hemorrhage. The prevalence of sonographic vasospasm and radiological delayed cerebral ischemia was analyzed, as was the correlation between different tomographic scales and these complications. Results: A total of 57 patients were studied. Sixty percent of the patients developed sonographic vasospasm, which was significantly associated with delayed cerebral ischemia and mortality. The Claassen and Hijdra scales were better correlated with the development of cerebral vasospasm (areas under the curve of 0.78 and 0.68) than was Fisher's scale (0.62). Thirty-two patients (56.1%) developed cerebral infarction on CT; the significantly associated factors were poor clinical grade at admission (p = 0.04), sonographic vasospasm (p = 0.008) and severity of vasospasm (p = 0.015). Only the semiquantitative Hijdra scale was significantly correlated with the development of radiological delayed cerebral ischemia (p = 0.009). The patients who presented cerebral infarction had worse neurological evolution and higher mortality. Conclusion: This is the first study in our environment on the subject. The Claassen and Hijdra tomographic scales showed better prognostic performance than the Fisher scale for the development of cerebral vasospasm. The finding of sonographic vasospasm could be a noninvasive criterion for the early detection of delayed cerebral ischemia and neurological deterioration in patients with aneurysmal subarachnoid hemorrhage.

RESUMO Objetivo: Determinar la prevalencia de vasoespasmo sonográfico y déficit isquémico diferido en pacientes con hemorragia subaracnoidea aneurismática, evaluar la correlación entre las diferentes escalas tomográficas con dichas complicaciones, así como estudiar los factores pronósticos en este grupo de pacientes. Métodos: Estudio prospectivo de pacientes ingresados a la unidad de cuidados intensivos con diagnóstico de hemorragia subaracnoidea aneurismática. Se analizó la prevalencia de vasoespasmo sonográfico e isquemia cerebral diferida radiológica, así como la correlación entre diferentes escalas tomográficas con dichas complicaciones. Resultados: Se estudiaron 57 pacientes. El 60% de los pacientes desarrollaron vasoespasmo sonográfico, el cual se asoció significativamente con isquemia cerebral diferida y mortalidad. Las escalas de Claassen y de Hijdra tuvieron una mejor correlación con el desarrollo de vasoespasmo cerebral (área bajo la curva de 0,78 y 0,68) que la de Fisher (0,62). Treinta y dos pacientes (56,1%) desarrollaron infarto cerebral en la TC, siendo los factores que se asociaron en forma estadísticamente significativa al mismo: pobre grado clínico al ingreso (p = 0,04), vasoespasmo sonográfico (p = 0,008) y severidad del vasoespasmo (p = 0,015). Solamente la escala semicuantitativa de Hijdra se correlacionó significativamente con el desarrollo de isquemia cerebral diferida radiológica (p = 0,009). Los pacientes que presentaron infarto cerebral tuvieron peor evolución neurológica y mayor mortalidad. Conclusion: Se presenta el primer estudio en nuestro medio sobre el tema. Las escalas tomográficas de Claassen y Hijdra presentaron un mejor rendimiento pronóstico que la de Fisher para desarrollo de vasoespasmo cerebral. El hallazgo de vasoespasmo sonográfico podría ser un criterio no invasivo de detección temprana de isquemia cerebral diferida y peoría neurológica en los pacientes con hemorragia subaracnoidea aneurismática.

Slow-flow phenomenon after drug-coated balloon angioplasty for lower-extremity arteries is associated with lack of prescribing of calcium channel blockers

This study aimed to investigate the relationship between prescription drugs and the slow-flow phenomenon after drug-coated balloon angioplasty. Of 30 patients, five (17%) presented with the slow-flow phenomenon. Patients with the slow-flow phenomenon were significantly less commonly prescribed calcium channel blockers than those without the slow-flow phenomenon (P ¼ 0.03). There was no intergroup difference in the prescription of angiotensin II receptor blockers and b-blockers. The clinical outcomes, including restenosis, thrombosis, target lesion revascularization, and death, did not differ between groups during the 10-month observation period.

Objective The combined detection of serum angiopoietin-like protein 8(ANGPTL8)and Vascular cell adhesion molecule-1(VCAM-1)levels was analyzed for the predictive value of cerebral vasospasm(CVS)after intracranial aneurysm embolization.Methods A total of 196 patients who underwent intracranial aneurysm embolization in our hospital from March 2019-March 2022 were selected as the study subjects,99 patients with CVS were in the CVS group,and 97 patients without CVS were in the non CVS group.Serum ANGPTL8 and VCAM-1 levels were detected by ELISA;the correlation between serum ANGPTL8 and VCAM-1 levels was analyzed by Pearson method,Logistic regression was used to analyze the influencing factors of CVS in patients undergoing intracranial aneurysm embolization;ROC curve was used to analyze the serum levels of ANGPTL8 and VCAM-1 to predict the cutoff value of CVS in patients undergoing intracranial aneurysm embolization;four grid table method was used to analyze the predictive value of ANGPTL8,VCAM-1 and their combination on the occurrence of CVS in patients undergoing intracranial aneurysm embolization.Results The differences between CVS and non-CVS groups were statistically significant in hypertension,Hunt-Hess grade,and Glasgow coma(GCS)scores(P＜0.05).The serum ANGPTL8 and VCAM-1 levels in the CVS group were significantly higher than those in the non-CVS group(P＜0.05).There was a positive correlation between serum ANGPTL8 and VCAM-1(r=0.468,P＜0.05).Multivariate analysis showed that high level of ANGPTL8(OR=3.652,95％CI:1.434-9.302),high level of VCAM-1(OR=2.619,95％CI:1.212-5.658),Hunt Hess grade Ⅲ-Ⅳ(OR=1.927,95％CI:1.104-3.362),GCS score of 3-8(OR=2.813,95％CI:1.257-6.295)were independent risk factors for CVS in patients undergoing intracranial aneurysm embolization.The AUC of serum ANGPTL8 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.844,and the cut-off value was 189.233 U/L;the AUC of serum VCAM-1 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.795,and the cutoff value was 17.984 mg/L.The accuracy,sensitivity and specificity of the combined prediction for CVS were 89.81％,93.94％and 85.57％,respectively,which were obviously higher than those of the single prediction.Conclusion The serum levels of ANGPTL8 and VCAM-1 in CVS group are obviously higher than those in non CVS group.The combination of the two has a high predictive value for CVS after intracranial aneurysm embolization.

Protective effects of histone deacetylase 6 specific inhibitor tubastatin A on subarachnoid hemorrhage in rats and the underlying mechanisms / 中南大学学报(医学版)

OBJECTIVES@#Subarachnoid hemorrhage (SAH) is a serious cerebrovascular disease. Early brain injury (EBI) and cerebral vasospasm are the main reasons for poor prognosis of SAH patients. The specific inhibitor of histone deacetylase 6 (HDAC6), tubastatin A (TubA), has been proved to have a definite neuroprotective effect on a variety of animal models of acute and chronic central nervous system diseases. However, the neuroprotective effect of TubA on SAH remains unclear. This study aims to investigate the expression and localization of HDAC6 in the early stage of SAH, and to evaluate the protective effects of TubA on EBI and cerebral vasospasm after SAH and the underlying mechanisms.@*METHODS@#Adult male SD rats were treated with modified internal carotid artery puncture to establish SAH model. In the first part of the experiment, rats were randomly divided into 6 groups: a sham group, a SAH-3 h group, a SAH-6 h group, a SAH-12 h group, a SAH-24 h group, and a SAH-48 h group. At 3, 6, 12, and 24 h after SAH modeling, the injured cerebral cortex of rats in each group was taken for Western blotting to detect the expression of HDAC6. In addition, the distribution of HDAC6 in the cerebral cortex of the injured side was measured by immunofluorescence double staining in SAH-24 h group rats. In the second part, rats were randomly divided into 4 groups: a sham group, a SAH group, a SAH+TubAL group (giving 25 mg/kg TubA), and a SAH+TubAH group (giving 40 mg/kg TubA). At 24 h after modeling, the injured cerebral cortex tissue was taken for Western blotting to detect the expression levels of HDAC6, endothelial nitric oxide synthase (eNOS), and inducible nitric oxide synthase (iNOS), terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling (TUNEL) staining to detect apoptosis, and hematoxylin and eosin (HE) staining to detect the diameter of middle cerebral artery.@*RESULTS@#The protein expression of HDAC6 began to increase at 6 h after SAH (P<0.05), peaked at 24 h (P<0.001), and decreased at 48 h, but there was still a difference compared with the sham group (P<0.05). HDAC6 is mainly expressed in the cytoplasm of the neurons. Compared with the sham group, the neurological score was decreased significantly and brain water content was increased significantly in the SAH group (both P<0.01). Compared with the SAH group, the neurological score was increased significantly and brain water content was decreased significantly in the SAH+TubAH group (both P<0.05), while the improvement of the above indexes was not significant in the SAH+TubAL group (both P>0.05). Compared with the sham group, the expression of eNOS was significantly decreased (P<0.01) and the expressions of iNOS and HDAC6 were significantly increased (P<0.05 and P<0.01, respectively) in the SAH group. Compared with the SAH group, the expression of eNOS was significantly increased, and iNOS and HDAC6 were significantly decreased in the SAH+TubA group (all P<0.05). Compared with the SAH group, the number of TUNEL positive cells was significantly decreased and the diameter of middle cerebral artery was significantly increased in the SAH+TubA group (both P<0.05) .@*CONCLUSIONS@#HDAC6 is mainly expressed in neurons and is up-regulated in the cerebral cortex at the early stage of SAH. TubA has protective effects on EBI and cerebral vasospasm in SAH rats by reducing brain edema and cell apoptosis in the early stage of SAH. In addition, its effect of reducing cerebral vasospasm may be related to regulating the expression of eNOS and iNOS.

The predominant neurological complication was vasospasm, isolated or associated with other complications such as hydrocephalus or rebleeding. Mortality was 54.29%.

Ventricular tachycardia and acute myocardial infarction induced by coronary artery spasm in patient without coronary artery disease

Coronary artery spasm, marked by coronary vasoconstriction, is one of the etiologies of myocardial ischemia, often presenting as vasospastic angina. Vasospastic angina is diagnosed when angina which predominantly occurs at rest, is accompanied by ST-segment changes in ECG, or in the setting of borderline ECG changes, a positive provocation test through coronary angiography is required. Although coronary artery spasms could manifest in wide clinical settings, the occurrence of ventricular arrhythmias and acute myocardial infarction solely caused by spasms without evidence of prior coronary artery disease is rare. This case report is about a 46-year-old man who presented with ventricular tachycardia and acute myocardial infarction that later was found to be secondary to coronary vasospasm observed directly through coronary angiography. We aim to emphasize the importance of coronary artery spasms as the etiology of malignant ventricular arrhythmias and acute myocardial infarction manifestation. Optimization in treatment and prevention shall reduce future life-threatening complications of coronary artery spasms.

Updates on aneurysmal subarachnoid hemorrhage: is there anything really new? / Atualizações em hemorragia subaracnóidea aneurismática: há algo realmente novo?

Abstract Background: Aneurysmal subarachnoid hemorrhage (aSAH) is a severe disease, with systemic involvement and complex diagnosis and treatment. Since the current guidelines were published by the AHA/ASA, Neurocritical Care Society and the European Stroke Organization in 2012-2013,there has been an evolution in the comprehension of SAH-associated brain injury and its multiple underlying mechanisms. As a result, several clinical and translational trials were developed or are underway. Objective: The aim of this article is to review some updates in the diagnosis and treatment of neurological complications of SAH. Methods: A review of PubMed (May, 2010 to February, 2022) was performed. Data was summarized. Results: Content of five meta-analyses, nine review articles and 23 new clinical trials, including pilots, were summarized. Conclusions:Advances in the comprehension of pathophysiology and improvements in critical care have been reflected in the reduction of mortality in SAH. However, despite the number of publications, the only treatments shown to be effective in adequate, well-controlled clinical trials are nimodipine and repair of the ruptured aneurysm. Thus, doubts about the optimal management of SAH still persist.

Resumo Antecedentes: Hemorragia subaracnóide aneurismática (HSAa) é uma doença grave, com envolvimento sistêmico, complexo diagnóstico e tratamento. Desde a publicação dos atuaisprotocolos de conduta pela AHA/ASA, NeurocriticalCare Society e EuropeanStrokeOrganization de 2012-2013, houve evolução na compreensão da lesão cerebral associada à HSA e seus múltiplos mecanismos subjacentes. Como resultado, muitos trabalhos clínicos e translacionais foram desenvolvidos ou estão em andamento. Objetivos: O objetivo deste artigo é revisar algumas das atualizações no diagnóstico e tratamento de complicações neurológicas de HSA. Métodos: Revisão de Pubmed (Maio de 201o a Fevereiro de 2022) foi realizada. Dados foram sintetizados. Resultados: O conteúdo de 5 metanálises, 9 artigos de revisão e 23 novos estudos clínicos, incluindo pilotos, foram sumarizados. Conclusões: Avanços na compreensão da fisiopatologia e melhorias no cuidado crítico têm se refletido na redução da mortalidade em HSA. Entretanto, apesar do volume de publicações, os únicos tratamentos que se mostraram efetivos com testes clínicos bem controlados são o uso de nimodipino e o tratamento dos aneurisma rotos. Assim, dúvidas acerca do manejo ideal em HSA ainda persistem.

Clinical value of hematoma volume estimated by 3D-Slicer in predicting symptomatic cerebral vasospasm after aneurysmal subarachnoid hemorrhage / 中华神经医学杂志

Objective:To investigate the clinical value of hematoma volume estimated by 3D-Slicer in predicting symptomatic cerebral vasospasm (sCVS) after aneurysmal subarachnoid hemorrhage (aSAH).Methods:CT images on admission of 84 aSAH patients, admitted to our hospital from January 2018 to June 2021, were collected. The hematoma volume of these patients was measured by 3D-Slicer (3D-Slicer hematoma volume). Patients were divided into sCVS group and non-sCVS group according to the occurrence of postoperative sCVS. The differences of 3D-Slicer hematoma volume, Fisher grading scale and modified Fisher grading scale between the two groups were compared by statistical methods, and the independent risk factors for sCVS after aSAH were screened. The differences of 3D-Slicer hematoma volume among patients with different Fisher grading scale or modified Fisher grading scale were compared.Results:There was no significant difference in Fisher grading scale and modified Fisher grading scale between sCVS group and non-SCVS group ( P>0.05), but the 3D-Slicer hematoma volume in sCVS group was significantly larger than that in non-SCVS group ( P<0.05). 3D-Slicer hematoma volume ( OR=1.061, 95%CI: 1.004-1.120, P=0.034) was independent risk factors for sCVS after aSAH. The comparison of 3D-Slicer hematoma volume among patients with different Fisher grading scale or modified Fisher grading scale showed statistical difference ( P<0.05). Conclusion:As compared with Fisher grading scale and modified Fisher grading scale, the hematoma volume measured by 3D-Slicer has more advantage in predicting sCVS after aSAH.

Reversible cerebral vasoconstriction syndrome characterized by postpartum headache: a case report / 中华围产医学杂志

We report the diagnosis and treatment of a case of reversible cerebral vasoconstriction syndrome characterized by postpartum thunderclap headache. The patient experienced a thunderclap headache on the second day after delivery, which gradually worsened. On postpartum day 4, she presented with sudden convulsion and hypertension on admission on May 19, 2020, and was initially diagnosed with postpartum eclampsia. We confirmed the diagnosis of reversible cerebral vasoconstriction syndrome based on the results of cranial magnetic resonance angiography (MRA) and other examinations and the consultation with neurologists. After antihypertensive and spasmolytic treatment, the patient's blood pressure returned to normal, and she was discharged on postpartum day 8. Reexamination with cranial MRA at 50 + days after delivery indicated that the cerebral vasospasm was relieved. No severe headaches or convulsions were observed during follow-up till June 2021.

Effect of ultra-early postoperative rehabilitation on hospital stay, complications and cerebral vasospasm in patients with aneurysmal subarachnoid hemorrhage: a meta-analysis / 国际脑血管病杂志

Objective:To conduct a meta-analysis for the effects of ultra-early postoperative rehabilitation on hospital stay, complications and vasospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH).Methods:PubMed, Embase, Cochrane Library, WOS, CNKI, CBM and Wanfang databases were searched by computers to collect control studies on ultra-early rehabilitation of aSAH. The retrieval time limit was from the establishment of the databases to August 2021. The methodological quality of the included literature was evaluated according to Cochrane Handbook Systematic Reviews Interventions, and the Revman 5.2 software was used for meta-analysis.Results:A total of 5 articles were obtained, with a total of 413 patients. The methodological quality of the 5 studies was lower (grade C). The results of the meta-analysis showed that the average length of stay in the intervention group (mean difference –4.14, 95% confidence interval [ CI] –10.69-2.42; P=0.22] and the incidence of complications (odds ratio 0.86, 95% CI 0.40-1.83; P=0.70) were lower than those in the control group, but there was no significant difference. The incidence of cerebral vasospasm in the intervention group was lower than that in the control group, and there was significant difference (odds ratio 0.31, 95% CI 0.18-0.53; P<0.001). Conclusions:Postoperative ultra-early rehabilitation in patients with aSAH can reduce the incidence of cerebral vasospasm without increasing the incidence of complications. Therefore, the ultra-early rehabilitation can be considered. The methodological quality of the literature included in this study is lower, and high-quality randomized controlled trials are needed to further verify the effects of ultra-early rehabilitation on hospital stay, complications, and cerebral vasospasm.

Salvinorin A alleviating cerebral vasospasm after subarachnoid hemorrhage through phosphatidylinositol 3-kinase/protein kinase B/endothelial nitric oxide synthase pathway / 解剖学报

Objective To investigate the effect of salvinorin A (SA) on alleviating cerebral vasospasm (CVS) after subarachnoid hemorrhage (SAH). Methods The SAH models were established by endovascular perforation method. Adult male SD rats (n = 91) were randomly divided into the sham group (sham), SAH model group (SAH), control group (SAH+DMSO) and drug administration group (SAH + SA). SA and DMSO were diluted with saline, and injected intraperitoneally at hour 24, hour 48 and hour 72 after SAH. At hour 72 after SAH, the neurological score was evaluated. The diameter and wall thickness of the internal carotid artery were observed through HE staining. Endothelin 1 (ET-1) ELISA kit and nitric oxide (NO) kit were used to observe the ET-1 concentration and NO content on the blood vessels of Willis circle. The expression of phosphorglated PI3K (p-PI3K), PI3K, phosphorylated Akt (p-Akt), Akt and endothelial nitric oxide synthase (eNOS) proteins were detected by Western blotting and the location of eNOS protein was observed by immunofluorescent staining. Results At hour 72 after SAH, SA could increase the neurological score, increase the vessel diameter and reduce the wall thickness of internal carotid artery. SA could reduce the ET-1 concentration and increase NO content in the blood vessels of Willis circle at hour 72 after SAH. SA could increase the ratio of p-PI3K/PI3K, p-Akt/Akt and the expression of eNOS proteins, which could be inhibited by PI3K inhibitor wortmannin and eNOS inhibitor L-NAME. eNOS expressed in vascular endothelial cells was detected by the immunofluorescence staining. Conclusion SA can alleviate CVS after SAH through PI3K/Akt/eNOS pathway.

@#Spontaneous subarachnoid haemorrhage (SAH) is a significant cause of stroke and may lead to severe neurological deficit or death. It is also associated with high morbidity and mortality for patients despite optimal medical and surgical treatment. Based on the World Health Organization the annual incidence of spontaneous SAH varies in different regions of the world between 2.0-22.5 per 100,000 populations with Finland and Japan having the highest incidence and South and Central America with lowest incidence.1

Relations of expressions of serum hypoxia inducible factor 2α and miR-21 with cerebral vasospasm in patients with aneurysmal subarachnoid hemorrhage after interventional embolization / 中华神经医学杂志

Objective:To investigate the relations of serum hypoxia inducible factor 2α (HIF-2α) and miR-21 expressions with cerebral vasospasm in patients with aneurysmal subarachnoid hemorrhage (aSAH) after interventional embolization.Methods:One hundred and seventy-four patients with aSAH underwent interventional embolization in our hospital from October 2017 to June 2019 were prospectively selected. DSA examination was performed 4 d after surgery, and severity of cerebral vasospasm was evaluated. Enzyme-linked immunosorbent assay was used to detect the level of serum HIF-2α and reverse transcription-PCR was employed to detect the serum miR-21 expression before and 3 and 7 d after interventional embolization. The clinical data and changes of serum HIF-2α and miR-21 expressions in patients with different degrees of cerebral vasospasm were compared. Correlation analysis was performed to analyze the relation of HIF-2α expression with miR-21 expression 3 and 7 d after interventional embolization. Receiver operating characteristics curve was used to analyze the diagnostic values of serum HIF-2α and miR-21 levels in cerebral vasospasm 3 d after interventional embolization.Results:There were 100 patients without vasospasm, and 20, 38 and 16 patients with mild, moderate and severe cerebral vasospasm, respectively. The serum levels of HIF-2α and miR-21 in patients with mild, moderate and severe cerebral vasospasm increased successively 3 and 7 d after interventional embolization, with significant differences ( P<0.05). Positive correlation was noted between expressions of HIF-2α and miR-21 in serum 3 and 7 d after interventional embolization ( P<0.05). Area under the curve (AUC) of HIF-2α in diagnosis of cerebral vasospasm was 0.748 ( 95%CI: 0.615-0.883, P=0.000) 3 d after interventional embolization. AUC of serum miR-21 level in diagnosis of cerebral vasospasm was 0.715 ( 95%CI: 0.590-0.842, P=0.000). AUC of serum HIF-2α combined with miR-21 in diagnosis of cerebral vasospasm was 0.893 ( 95%CI: 0.792-0.985, P=0.000). When diagnostic critical points of HIF-2α and miR-21 were 82.75 pg/mL and 1.15, the sensitivity, accuracy and negative predictive value of HIF-2α combined with miR-21 in the diagnosis of cerebral vasospasm were higher than those of HIF-2α or miR-21 alone. Conclusion:The expressions of serum HIF-2α and miR-21 in patients with aSAH after interventional embolization can effectively predict the occurrence of cerebral vasospasm, and may be involved in the occurrence and development of cerebral vasospasm.

Efficacy and safety of Fasudil on vasospasm caused by subarachnoid hemorrhage in elderly patients / 中华老年医学杂志

Objective:To evaluate the efficacy and safety of fasudil on vasospasm caused by subarachnoid hemorrhage in elderly patients.Methods:A total of 100 elderly patients with subarachnoid hemorrhage admitted to our hospital from January 2015 to May 2018 were enrolled as research objects.They were randomly divided into the Fasudil group(n=50, receiving the Rho kinase inhibitor Fasudil therapy)and the Nimodipine group(n=50, receiving Nimodipine therapy). The cerebral vasospasm and cerebral infarction lesions, the ability of daily life, clinical prognostic score, the incidence of symptomatic cerebral vasospasm and adverse reactions during treatment were evaluated and compared between the two groups.Results:After treatment, the incidences of cerebral vasospasm and cerebral infarction in Fasudil group were 2.04%(1/49)and 6.12%(3/49), respectively, which were lower than those in the Nimodipine group[12.50%(6/48)and 20.83%(10/48), respectively]( χ2=6.134 and 6.794, P=0.047 and 0.033). The scores of daily living ability was better in the Fasudil group than in the Nimodipine group(16.09±1.06 vs.22.91±1.66, t=7.721, P=0.026). The incidence of adverse reactions was lower in the Fasudil group than in the Nimodipine group(4.08% or 2/49 vs.16.7% or 8/48, χ2=6.362, P=0.040). There was no statistically significant difference in the proportion of patients with good prognosis between Fasudil group and Nimodipine group. Conclusions:Rho kinase inhibitor Fasudil can effectively prevent and improve cerebral vasospasm caused by subarachnoid hemorrhage, which is beneficial for improving the clinical prognosis and quality of life of the elderly patients with subarachnoid hemorrhage.

Delayed sudden blindness from unilateral ophthalmic artery vasospasm following endoscopic sinus surgery?

@#Endoscopic sinus surgery (ESS) is a generally benign, minimally invasive procedure used for management of paranasal sinus diseases, although complications may occur due to proximity of vital structures such as the brain, orbit and great vessels.1 The overall ESS major complication rate is 0.5-1%, of which orbital injury accounts for 0.09% due to direct trauma.2 We report a case of unilateral delayed sudden visual loss without orbital trauma observed intraoperatively or on post[1]operative imaging studies, following a seemingly routine endoscopic sinus surgery for chronic rhinosinusitis.

Eficácia e segurança da milrinona no tratamento do vasoespasmo cerebral após hemorragia subaracnóidea: uma revisão sistemática / Efficacy and safety of milrinone in the treatment of cerebral vasospasm after subarachnoid hemorrhage: a systematic review

RESUMO Objetivo: Revisar sistematicamente a evidência atual da eficácia de milrinona no tratamento do vasoespasmo cerebral após hemorragia subaracnóidea. Métodos: Triaram-se as bases de dados Pubmed®, Cochrane e Embase quanto a artigos publicados entre abril de 2001 e fevereiro de 2019. Dois revisores independentes realizaram uma triagem metodológica da qualidade e a extração dos dados dos estudos. Resultados: Encontraram-se 22 estudos considerados relevantes, sendo que apenas um deles era um ensaio randomizado controlado. Os estudos demonstraram acentuada heterogeneidade e debilidade de seus critérios metodológicos. A maioria dos pacientes apresentava vasoespasmo moderado a grave. O principal método para diagnóstico do vasoespasmo foi a angiografia. Em três estudos, realizou-se administração de milrinona por via intra-arterial; em nove estudos, a administração foi endovenosa, e, em seis estudos, utilizaram-se ambas as vias de administração. A via intratecal foi utilizada em dois estudos, em um estudo, a administração foi realizada via cisterna e, em um estudo, a via de administração foi a endovascular. Os efeitos colaterais de milrinona foram descritos em seis estudos. Vinte e um estudos indicaram a resolução do vasoespasmo. Conclusão: A evidência atual indica que o uso de milrinona teve um papel no tratamento do vasoespasmo após hemorragia subaracnóidea aneurismática. Contudo, só foi realizado um ensaio randomizado controlado, com baixo nível de qualidade. Nossos achados indicam a necessidade de futuros estudos randomizados controlados com desfechos centrados no paciente, com o fim de proporcionar recomendações definitivas.

ABSTRACT Objective: To systematically review the current evidence on the efficacy of milrinone in the treatment of cerebral vasospasm after subarachnoid hemorrhage. Methods: The Pubmed®, Cochrane and Embase databases were screened for articles published from April 2001 to February 2019. Two independent reviewers performed the methodological quality screening and data extraction of the studies. Results: Twenty-two studies were found to be relevant, and only one of these was a randomized control trial. Studies showed marked heterogeneity and weaknesses in key methodological criteria. Most patients presented with moderate to severe vasospasm. Angiography was the main method of diagnosing vasospasm. Intra-arterial administration of milrinone was performed in three studies, intravenous administration was performed in nine studies, and both routes of administration in six studies; the intrathecal route was used in two studies, the cisternal route in one study and endovascular administration in one study. The side effects of milrinone were described in six studies. Twenty-one studies indicated resolution of vasospasm. Conclusion: The current evidence indicates that milrinone may have a role in treatment of vasospasm after aneurysmal subarachnoid hemorrhage. However, only one randomized control trial was performed, with a low quality level. Our findings indicate the need for future randomized control trials with patient-centered outcomes to provide definitive recommendations.

Ergotism, a relatively unknown mimic of vasculitis: A case report and review of literature / Ergotismo: un imitador poco conocido de vasculitis. Reporte de caso y revisión de la literatura

ABSTRACT Introduction: Ergotism is a vasospasm that affects visceral and peripheral muscle arteries. Classically, symmetrical involvement of lower limb arteries is described, and is often associated with a history of chronic consumption of ergotamine derived medications (Cafergot). Case report: A 22 year-old healthy man with infectious mononucleosis syndrome, who presented with a sudden onset of paraesthesias in the lower limbs, as well as livedo reticularis. The initial diagnosis was a medium-sized vessel vasculitis (polyarteritis nodosa). The symptoms were preceded by the administration of Cafergot for headache treatment, and resolved spontaneously. The magnetic resonance angiography (MRA) of the lower limbs showed occlusion of peroneal arteries, with filiform distal flow. Other infectious, autoimmune and cardiovascular origins were ruled out. Discussion: Ergotism is an important differential diagnosis in the study of the patient with vasculitis, especially in acute onset presentations. Its treatment is the suspension of the causal drug, with vasodilator and surgical vascular procedures, if necessary. Conclusions: Ergotism is an imitator of vasculitis, especially in young patients with a history of difficult to control migraine. The concomitant administration of CYP3A4 inhibitors (mainly, protease inhibitors and macrolides) enhances the toxic effects of ergot.

RESUMEN Introducción: El ergotismo es un vasoespasmo que afecta las arterias musculares periféricas y viscerales. Clásicamente se describe la afectación simétrica de las arterias de las extremidades inferiores, a menudo asociada con el consumo crónico de medicamentos derivados de ergotamina (Cafergot®). Caso clínico: Varón sano de 22 anos con síndrome de mononucleosis, presentó parestesias en las extremidades inferiores y livedo reticularis de forma súbita, el diagnóstico inicial fue una vasculitis de mediano vaso (poliarteritis nodosa). Los síntomas fueron precedidos por la administración de Cafergot® para el tratamiento de cefalea, y se resolvieron espontáneamente. La angiografía por resonancia magnética (ARM) de las extremidades inferiores mostró oclusión de las arterias peroneas, con flujo distal filiforme. Se descartaron otras etiologías infecciosas, autoinmunes y cardiovasculares. Discusión: Los ergotismos son un diagnóstico diferencial importante en el estudio del paciente con vasculitis, especialmente en presentaciones de inicio agudo. Su tratamiento es la suspensión del fármaco causal, vasodilatadores y procedimientos vasculares quirúrgicos, si es necesario. Conclusiones: El ergotismo es un imitador de vasculitis, especialmente en pacientes jóvenes con antecedentes de migrana de difícil control. La administración concomitante de inhibidores del CYP3A4 (principalmente, inhibidores de proteasa y macrólidos) potencia los efectos tóxicos del ergot.
