The Management of High-Frequency Episodic and Chronic Migraines with Calcitonin Gene-Related Peptide Monoclonal Antibody
Introduction. 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.
Objective: to evaluate safety and effectiveness of fremanezumab in patients with high-frequency episodic migraine (HF EM) and chronic migraine (CM).
Materials 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.
Results. 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).
Conclusion. 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. A single dose of fremanezumab (675 mg) resulted in effective migraine prevention, decline in comorbid anxiety and depression, and improved quality of life during 3-month follow-up
Наследственная прогрессирующая поясно-конечностная мышечная дистрофия 2А типа (кальпаинопатия): клинический случай
Presents clinical case the hereditary progressive muscular dystrophy type 2A (calpainopathy). Shows diagnostic difficulties and feature of presents clinical observations. This case is significance, as in the domestic scientific literature presents few articles on clinical examples of this muscle pathology.Представлен клинический случай наследственной аутосомно-рецессивной прогрессирующей поясно-конечностной мышечной дистрофии типа 2А – кальпаинопатии. Рассмотрены диагностические трудности и особенности представленного клинического наблюдения. С учетом того, что в отечественной научной литературе представлены единичные публикации о клинических примерах данной мышечной патологии, настоящее наблюдение имеет особую значимость
Наследственная прогрессирующая конечностно-поясная мышечная дистрофия 2А типа (кальпаинопатия): обзор литературы
The Russian literature gives inadequate attention to the problem of one of the most common form of autosomal recessive progressive limb-girdle muscular dystrophies type 2A (LGMD2A) (calpainopathy). This paper highlights current views on the physiological role of calpain 3 protein, possible pathogenetic mechanisms for the development of myodystrophy, diagnostic criteria, and therapeutic approaches. Clinical neurologists» awareness of LGMD2A will be able to reduce the time to a correct diagnosis, to take measures to slow down the rate of disease progression, to make medical and genetic counselling, a follow-up, and monitoring, as well as to use measures for the physical and social adaptation of a patient. Key words: progressive limb-girdle muscular dystrophy, calpainopathy, calpain 3, inherited myopathy, creatinine phosphokinase, electromyography, muscle magnetic resonance imaging, genetic analysis, muscle biopsy, differential diagnosis.В отечественной литературе недостаточно внимания уделено проблеме одной из наиболее частой формы аутосомно-рецессивных прогрессирующих конечностно-поясных миодистрофий – кальпаинопатии (КПМД2А). В настоящей статье освещены современ- ные взгляды на физиологическую роль белка кальпаина-3, возможные патогенетические механизмы развития миодистрофии, диагностические критерии и терапевтические подходы. Осведомленность клинических неврологов в отношении КПМД2А позво- лит сократить сроки постановки правильного диагноза, предпринять меры по замедлению темпа прогрессирования заболевания, осуществлять медико-генетическое консультирование, наблюдение и мониторинг, а также своевременно применять меры по физической и социальной адаптации пациента
Safety and efficacy of endovascular patent foramen ovale closure: the first results of a Russian multicenter study
Patent foramen ovale (PFO) is detectable in more than 25% of the adult population and is generally clinically insignificant. However, it can be a cause of paradoxical embolism in some cases. Randomized trials indicate that endovascular PFO closure in patients with a history of cryptogenic stroke is an effective method for the secondary prevention of catastrophic brain damage.Objective: to study the safety and efficiency of endovascular PFO closure in young patients with a history of cryptogenic stroke.Patients and methods. Sixty-two patients, including (22 males and 40 females) women, underwent percutaneous PFO closure in May 2018 to March 2020. The patients' mean age was 37.4±7.6 years. The inclusion criteria were a prior cryptogenic ischemic stroke lasting less than 12 months and PFO with a high risk for paradoxical embolism (PFO concurrent with atrial septal aneurysm or hypermobility; PFO, ≥2 mm size; the presence of the Chiari network and/or the Eustachian valve).Results and discussion. The technical success of the operation was achieved in all cases. In 50 (80.6%) patients, the right chamber of the heart was completely isolated from the left one in the first 3 months. During the first year, the atria were also completely isolated in 10 (16.1%) patients. A left-to-right shunt persisted in 2 (3.2%) patents 12 months later. Two patients were found to have main procedural complications: one had perioperative atrial fibrillation and the other had pseudoaneurysm formation at the puncture site.Conclusion. Endovascular PFO closure is a safe and effective operation for the secondary prevention of recurrent ischemic stroke. In our study, blood shunting through the PFO was stopped in 96.6% of patients at less than 6 months after surgery, which suggests that there is a rapid and effective reduction in the risk of paradoxical embolism
Burden and attitude to resistant and refractory migraine: a survey from the European Headache Federation with the endorsement of the European Migraine & Headache Alliance
Background: New treatments are currently offering new opportunities and challenges in clinical management and research in the migraine field. There is the need of homogenous criteria to identify candidates for treatment escalation as well as of reliable criteria to identify refractoriness to treatment. To overcome those issues, the European Headache Federation (EHF) issued a Consensus document to propose criteria to approach difficult-to-treat migraine patients in a standardized way. The Consensus proposed well-defined criteria for resistant migraine (i.e., patients who do not respond to some treatment but who have residual therapeutic opportunities) and refractory migraine (i.e., patients who still have debilitating migraine despite maximal treatment efforts). The aim of this study was to better understand the perceived impact of resistant and refractory migraine and the attitude of physicians involved in migraine care toward those conditions. Methods: We conducted a web-questionnaire-based cross-sectional international study involving physicians with interest in headache care. Results: There were 277 questionnaires available for analysis. A relevant proportion of participants reported that patients with resistant and refractory migraine were frequently seen in their clinical practice (49.5% for resistant and 28.9% for refractory migraine); percentages were higher when considering only those working in specialized headache centers (75% and 46% respectively). However, many physicians reported low or moderate confidence in managing resistant (8.1% and 43.3%, respectively) and refractory (20.7% and 48.4%, respectively) migraine patients; confidence in treating resistant and refractory migraine patients was different according to the level of care and to the number of patients visited per week. Patients with resistant and refractory migraine were infrequently referred to more specialized centers (12% and 19%, respectively); also in this case, figures were different according to the level of care. Conclusions: This report highlights the clinical relevance of difficult-to-treat migraine and the presence of unmet needs in this field. There is the need of more evidence regarding the management of those patients and clear guidance referring to the organization of care and available opportunities
