Chronic fibrosing progressing interstitial lung disease: a decision of Multidisciplinary Expert Board

The natural course of some interstitial lung diseases (ILD) is characterized by progressive fibrosing phenotype resembling idiopathic pulmonary fibrosis (IPF). Until recently, the antifibrotic drug nintedanib was approved for treatment of the only fibrosing ILD which was IPF. A new indication for this drug which has been registered in Russian Federation in 2021 includes other fibrosing ILDs with progressive phenotype (PF-ILDs) and ILD associated with systemic scleroderma (SS-ILD). The aim of this publication is to describe general considerations of the decision of Multidisciplinary Expert Board on diagnosis and treatment of PF-ILDs including SS-ILD. Results. According to the extension in nintedanib use mentioned above, the Expert Board created an algorithm for diagnosis and treatment of patients with PF-ILDs and criteria for nuntedanib administration in PF-ILDs. Conclusion. Antifibrotic therapy is needed for patients with PF-ILDs with the failure of the stanrard therapy. In those patients antifibrotic treatment should be initiated as early as possible to better preserve the lung functionПри формировании фибротических изменений в легких многие интерстициальные заболевания легких (ИЗЛ) могут приобретать прогрессирующее течение. По прогнозу выживаемости, риску летальности и обострений такой фенотип ИЗЛ при отсутствии антифибротической терапии очень близок к идиопатическому легочному фиброзу. В 2020 г. в Российской Федерации разрешено использование антифибротического препарата нинтеданиб при фиброзирующих ИЗЛ с прогрессирующим фиброзным фенотипом (ПФФ) и при ИЗЛ, связанных с системной склеродермией. Целью работы Междисциплинарного Совета экспертов явилось ознакомление с основными положениями резолюции Междисциплинарного Совета экспертов о диагностике и лечении ИЗЛ ПФФ. Результаты. В декабре 2020 г. состоялся Междисциплинарный Совет экспертов, по результатам работы которого разработаны алгоритм диагностики и ведения пациентов с ИЗЛ ПФФ и критерии отбора больных для назначения антифибротической терапии. Заключение. Установлено, что в случае когда при стандартной терапии ИЗЛ ПФФ клиническое состояние пациента и легочная функция и / или фибротические изменения в легких по данным компьютерной томографии высокого разрешения не стабилизируются, показана антифибротическая терапия нинтеданибом. Начиная антифибротическую терапию в возможно более ранние сроки заболевания, можно замедлить прогрессирующее снижение легочной функции при более сохранных исходных показателях

Practical recommendations for choosing an immunobiological preparation for the treatment of severe bronchial asthma of T2-endotype

Biological therapy of bronchial asthma (BA) is a modern method of treating severe forms of the disease, that are uncontrolled by traditional pharmacotherapeutic approaches. Currently, 5 monoclonal antibody (AT) preparations are registered in the world for the treatment of severe bronchial asthma (SBA) of the T2 endotype (T2-SBA) – antibodies, binding to immunoglobulin (Ig) E (anti-IgE – omalizumab), interleukin antagonists (IL)-5 (anti-IL-5 – mepolizumab, resizumab) and its receptor (anti-IL-5Rα – benralizumab), as well as antibodies, that selectively bind to the IL-4 and -13 receptor (anti-IL-4 /13Rα – dupilumab). The article presents data on the effectiveness of these drugs in relation to the key characteristics of SBA, formulates clinical and laboratory criteria, the study of which in real practice can potentially predict the likelihood of a clinical response to a particular type of biological therapy. An algorithm is proposed for choosing a targeted therapy strategy for patients with SBA, clinically associated with allergies, for patients with severe non-allergic eosinophilic BA and for patients with eosinophilic BA of a combined phenotype.Биологическая терапия бронхиальной астмы (БА) представляет собой современный метод лечения тяжелых форм заболевания, неконтролируемых при помощи традиционных фармакотерапевтических подходамов. В настоящее время в мире зарегистрированы 5 препаратов моноклональных антител (АТ) для лечения тяжелой бронхиальной астмы (ТБА) Т2-эндотипа (Т2-ТБА) – АТ, связывающие иммуноглобулин (Ig) Е (анти-IgE – омализумаб), антагонисты интерлейкина (IL)-5 (анти-IL-5 – меполизумаб, реслизумаб) и его рецептора (анти-IL-5Rα – бенрализумаб), а также АТ, избирательно связывающиеся с рецептором IL-4 и -13 (анти-IL-4/13Rα – дупилумаб). В статье приведены данные об эффективности указанных препаратов в отношении ключевых характеристик ТБА, сформулированы клинико-лабораторные критерии, при исследовании которых в реальной практике потенциально может быть предсказана вероятность клинического ответа на тот или иной вид биологической терапии. Предложен алгоритм выбора стратегии таргетной терапии для пациентов с ТБА, клинически ассоциированной с аллергией, для больных тяжелой неаллергической эозинофильной БА и для страдающих эозинофильной БА сочетанного фенотип

Diagnostic and treatment options for patients with COPD as part of real clinical practice. Approaches to the treatment of patients with various phenotypes according to GOLD (2019): Materials of the Council of Experts of the Siberian Federal District, Chita and Buryatia, dated 03.15.19

Chronic obstructive pulmonary disease (COPD) is a global problem in modern medicine. In recent years, the medical community's understanding of COPD has changed significantly, which is primarily due to the emergence of a new classification and the identification of various phenotypes of the disease. These changes could not affect the tactics of COPD treatment. The article discusses not only the debatable issues of treating COPD; it provides an overview of changes in international (Global Initiative for Chronic Obstructive Lung Disease, 2018) and national (2019) recommendations, but also the significance and benefits of triple therapy in terms of evidence-based medicine as well as the benefits of extra-fine drugs in the treatment of bronchial obstructive syndrome

Limbic Encephalitis Associated with COVID-19

Limbic encephalitis (LE) is an inflammatory disease of the brain, in which lesion is anatomically limited in structures of the limbic system. In some cases, LE can start with symptoms of limbic dysfunction with further involvement of other regions of the brain. Classic LE syndrome includes such symptoms as the development of personality disorders, depression, sleep disorders, epileptic seizures, hallucinations and cognitive disorders (short-term and long-term memory impairment). The information of clinical examination, electroencephalogram (EEG), magnetic resonance imaging (MRI) and cerebrospinal fluid studies (CSF) suggest the diagnosis of LE in most patients with Coronavirus Disease 2019 (COVID-19)

Proteomics-Based Regression Model for Assessing the Development of Chronic Lymphocytic Leukemia

The clinical course of chronic lymphocytic leukemia (CLL) is very ambiguous, showing either an indolent nature of the disease or having latent dangerous progression, which, if diagnosed, will require an urgent therapy. The prognosis of the course of the disease and the estimation of the time of therapy initiation are crucial for the selection of a successful treatment strategy. A reliable estimating index is needed to assign newly diagnosed CLL patients to the prognostic groups. In this work, we evaluated the comparative expressions of proteins in CLL blood cells using a label-free quantification by mass spectrometry and calculated the integrated proteomic indexes for a group of patients who received therapy after the blood sampling over different periods of time. Using a two-factor linear regression analysis based on these data, we propose a new pipeline for evaluating model development for estimation of the moment of therapy initiation for newly diagnosed CLL patients

DRESS/DIHS-синдром, индуцированный приемом сульфасалазина

Among the manifestations of drug hypersensitivity, DRESS/DIHS syndrome is of particular importance. The clinical manifestations include rash, enlarged lymph nodes, fever, hepatitis, leukocytosis with eosinophilia, as well as the involvement of other organs and systems. The most common causative agents include anticonvulsants, antidepressants, sulfanilamides, non-steroidal anti-inflammatory drugs, and allopurinol, but the list is constantly expanding. The exact pathogenesis of DRESS/DIHS syndrome is currently unclear. Timely diagnosis and adequate therapy can improve prognosis of this disease. In our clinical case, DRESS syndrome developed after the patient was administered sulfasalazine for erosive proctosigmoiditis. In order to ensure adequate prevention, early diagnosis, and proper management of DRESS syndrome, it is necessary to raise awareness of practitioners of different specialties about the possibility of developing this undesirable reaction to pharmacotherapy.Среди проявлений лекарственной гиперчувствительности особое место занимает DRESS/DIHS-синдром — реакция на лекарства с эозинофилией и системными симптомами (drug reaction with eosinophilia and systemic symptoms — DRESS), также называемая синдромом лекарственной гиперчувствительности (drug-induced hypersensitivity syndrome — DIHS), проявляющийся высыпаниями, увеличением лимфатических узлов, лихорадкой, гепатитом, лейкоцитозом с эозинофилией, а также вовлечением других органов и систем. Развитие данного синдрома чаще связано с применением противосудорожных средств, антидепрессантов, сульфаниламидов, нестероидных противовоспалительных препаратов и аллопуринола, однако список причинно-значимых средств постоянно расширяется. Точный патогенез DRESS/DIHS-синдрома в настоящее время неясен, однако при своевременной диагностике и адекватной терапии прогноз может улучшиться. Представлено клиническое наблюдение пациента с DRESS/DIHS-синдромом, который развился после приема сульфасалазина по поводу эрозивного проктосигмоидита. Для обеспечения адекватной профилактики, ранней диагностики и корректной тактики ведения такого заболевания, как DRESS/DIHS-синдром, необходимо повышать информированность практикующих врачей разных специальностей о возможности развития такой нежелательной реакции на фоне фармакотерапии

Untargeted mass spectrometry-based metabolomics approach unveils molecular changes in raw and processed foods and beverages

n our daily lives, we consume foods that have been transported, stored, prepared, cooked, or otherwise processed by ourselves or others. Food storage and preparation have drastic effects on the chemical composition of foods. Untargeted mass spectrometry analysis of food samples has the potential to increase our chemical understanding of these processes by detecting a broad spectrum of chemicals. We performed a time-based analysis of the chemical changes in foods during common preparations, such as fermentation, brewing, and ripening, using untargeted mass spectrometry and molecular networking. The data analysis workflow presented implements an approach to study changes in food chemistry that can reveal global alterations in chemical profiles, identify changes in abundance, as well as identify specific chemicals and their transformation products. The data generated in this study are publicly available, enabling the replication and re-analysis of these data in isolation, and serve as a baseline dataset for future investigations
