High prevalence of migraine and its impact on quality of life requires the development of original agents. In 2020, fremanezumab, a new calcitonin gene-related peptide monoclonal antibody was authorized in Russia. \u0000Objective: to evaluate safety and effectiveness of fremanezumab in patients with high-frequency episodic migraine (HF EM) and chronic migraine (CM). \u0000Materials and methods. We assessed 60 patients at the age of 35.5 8.96 years (85%, females) with HFEM and CM with and without aura who were either receiving preventive treatment or not. Fremanezumab was administered subcutaneously at a single dose of 675 mg. The study participants were followed-up for efficacy in 3 months. The investigators assessed change in the number of days with headache per month as well as headache intensity, its impact on the daily activities, anxiety, and depression. \u0000Results. By the end of month 3 post dosing, the number of days with headache decreased by 50% in 76.7% of participants where 77.8% of individuals suffered from HF EM and 72.7% of individuals had CM while headache intensity decreased in all the patients equally. No response (decrease in the number of days with headache by 30%) was reported in 15% of participants including 14.8% of individuals with HF EM and 15.2% of individuals with CM. By the end of study month 3, 81% of participants demonstrated no anxiety symptoms and 79% of participants showed no depression with significant MIDAS and HIT-6 score decline in both groups. Only 3 (5%) patients noted adverse events (redness, itching at the administration site). \u0000Conclusion. We documented higher fremanezumab safety and effectiveness in patients with EM and CM in real-world practice as compared to fremanezumab safety and efficacy in randomized clinical trials.

Due to the prevalence of dysphagia in patients with Parkinson's disease (PD) and its complications such as aspiration pneumonia, which is the main cause of death in these patients, PD-related disability can be prevented by early diagnosis and treatment of dysphagia. \u0000Objective. The present study was aimed at investigating the frequency of dysphagia in PD patients. \u0000Materials and methods. This cross-sectional study included 150 PD patients visiting a Neurology Clinic. The severity of PD was determined based on the Unified Parkinson Disease Rating Scale (UPDRS) and modified Hoen and Yahr (HYS) Scale. The Munich Dysphagia Test-Parkinson's disease (MDT-PD) questionnaire was used to assess dysphagia. Comparisons were made using generalized Fisher exact, Chi-square, ANOVA, and KruskalWallis tests. Predictive factors were analyzed using logistic regression. Statistical analyses were performed at significance level of 0.05. \u0000Results. Out of all 150 patients referred to the Clinic, the prevalence of dysphagia requiring attention was 25.3% (n = 38). The patients of the three groups according to the MDT-PD (no noticeable dysphagia, noticeable oropharyngeal, and dysphagia with aspiration risk) had a significant difference only in terms of the PD duration (p 0.001). In the predicting of dysphagia, the longer PD duration (p = 0.011) and homemaker occupation (p = 0.033) were protective factors, while female gender was a risk factor (p = 0.011). \u0000Conclusion. The prevalence of dysphagia requiring attention in the studied patients was 25.3%. It decreased with the longer duration of the disease, and its prevalence was lower in homemaker patients, while the odds of dysphagia was 5.8 times higher in women than in men.","PeriodicalId":36946,"journal":{"name":"Annals of Clinical and Experimental Neurology","volume":"61 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87543786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stroke energy induces mechanical injury of tissues to launch secondary damage, i.e. neurotransmission, blood-brain barrier disruption, blood infiltration of brain tissues, cytokine and chemokine overexpression, and other processes. Activated by the injury, microglia plays a special part to initially 'protect' intact tissues from the products of necrosis and apoptosis. After the injury, microglia rapidly differentiates to phenotypes М1 and М2. Pro-inflammatory phenotype М1 produces neuronal cytotoxic cytokines including tumor necrosis factor-, interleukins (IL)-6 and IL-1, and NO that induce apoptosis while phenotype М2 secretes IL-4 and IL-13 that may supposedly reduce inflammation and improve recovery of brain tissues. М2 response lasts much less than М1 response, and increasing pro-inflammatory activation leads to further neuronal death, which affects cognitive and physical status of patients with head injury.

Modern transplantation and biological therapy methods are associated with a wide range of adverse events and complications. Incidence and variety of neurological complications mostly depend on myelo- and immunosuppression severity and duration as well as on donor's and recipient's characteristics. The most frequent complications involving the nervous system include neurotoxic reactions, infections, autoimmune and lymphoproliferative diseases, and dysmetabolic conditions as well as cerebrovascular complications that potentially affect transplantation outcomes. \u0000Objective. To evaluate the impact of post-transplantation cerebrovascular events (CVEs) on transplantation outcomes in patients with hematologic malignancies. \u0000Materials and methods. We analyzed 899 transplantations performed at the Raisa Gorbacheva Memorial Research Institute for Pediatric Oncology, Hematology, and Transplantation, Pavlov First Saint Petersburg State Medical University, from 2016 to 2018. We assessed transplantation parameters and donor's and recipient's characteristics by intergroup comparison, pseudo-randomization (propensity score matching), KaplanMeier survival analysis, and log-rank tests. \u0000Results. Post-transplantatively, CVEs developed in 2.6% (n = 23) of cases: 13 (1.4%) ischemic strokes and 11 (1.2%) hemorrhagic strokes or intracranial hemorrhages were diagnosed. CVEs developed on days 99.5 39.2 post hematopoetic stem cell transplantation (HSCT). There were more patients with non-malignant conditions in the CVE group as compared to the non-CVE group (21.7% vs 7.9%; p = 0.017). Patients with CVE had a significantly lower Karnofsky index (75.6 21.3 vs 85.2 14.9; p = 0.008). Statistically, we also note some non-significant trends: patients with CVE more often underwent allogenic HSCT (82.6% vs 64.0%; p = 0.077) while donors were more often partially (rather than totally) HLA compatible for recipients (39.1% vs 21.1%; p = 0.33). Patients with CVE more often had a history of venous thromboses (13.3% vs 4.2%; p = 0.077). Post-HSCT stroke decreased post-transplantation longevity by approximately 3 times (331.8 81.6 vs 897.9 25.4 post HSCT; p = 0.0001). In the CVE group, survival during first 180 days post HSCT (landmarks post-HSCT Day+60 and Day+180) was significantly lower as compared to that in the CVE-free group. If CVE developed during first 30 days and 100 days post HSCT, vascular catastrophe did not affect post-HSCT survival significantly. \u0000Conclusion. Whereas ischemic stroke is a long-term HSCT complication (beyond D+100 post transplantation), hemorrhagic stroke is a short-term complication (D0D+100 post HSCT). CVEs affect survival in patients with hematologic malignancies, especially those developed between D+60 and D+180 post HSCT. History of venous abnormalities, low Karnofsky index at HSCT initiation, and the type of allogenic HSCT, especially from half-matched donors, can be considered as negative outcome risk factors in post-HSCT CVE.","PeriodicalId":36946,"journal":{"name":"Annals of Clinical and Experimental Neurology","volume":"42 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82067958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
