Обоснование, Хронический полипозный риносинусит (ПРС) отличается широкой вариабельностью клинических проявлений. Для практического врача важно прогнозировать развитие заболевания, оценить риск рецидива и подобрать наиболее эффективный способ лечения в каждом конкретном случае. В настоящий момент отсутствуют стандартизированные, валидизированные диагностические биомаркеры, которые можно использовать в качестве предикторов клинического течения ПРС. Цель, Разработать алгоритм диагностики и лечения разных фенотипов ПРС на основе клинических и лабораторных показателей. Материалы и методы, Пациенты с ПРС были разделены на 3 группы: 1-я группа - ПРС без аллергии и бронхиальной астмы (БА), 2-я группа - ПРС в сочетании с аллергическим ринитом (АР) и/или аллергической БА (аБА), 3-я группа - ПРС в сочетании с неаллергической БА (нБА). Всем пациентам проводилась эндоскопия полости носа и взятие биопсии ткани носовых полипов, аллергологическое обследование, гистологическое исследование стромы полипов с определением степени выраженности лейкоцитарной инфильтрации и эозинофильно-нейтрофильного индекса. Результаты, Фенотипы ПРС достоверно различаются между собой по выраженности клинических проявлений риносинусита (р0,005), уровню эозинофилов крови (р0,001) и степени лейкоцитарной инфильтрации стромы полипов (р0,004). При этом при сочетании ПРС с АР, аБА и нБА отмечался более выраженный воспалительный ответ, что подтверждает факт взаимного влияния этих патологических процессов друг на друга. Также установлено, что абсолютное содержание эозинофилов в периферической крови не коррелирует с выраженностью эозинофильно-клеточной инфильтрации стромы носовых полипов, а следовательно, не несет клинически значимой информации об интенсивности локального воспалительного процесса в отличие от доказанной ранее взаимосвязи уровня эозинофилов в крови и в мокроте у больных БА. Заключение, Показана целесообразность фенотипирования ПРС в зависимости от сопутствующей патологии, что является необходимым инструментом при подборе терапии в каждом конкретном случае. Поэтому для улучшения контроля и предупреждения рецидива ПРС предложен лечебно-диагностический алгоритм ведения пациентов в зависимости от фенотипа заболеванияChronic rhinosinusitis with nasal polyps (CRSwNP) may vary in clinical manifestations and can often be associated with a number of comorbid diseases. For a practitioner it is important to forecast the development of the disease, evaluate the risk of relapse and select the most efficient method of treatment in each clinical case. At present, there are no standardized and validated diagnostic biomarkers that could be used as predictors of CRSwNP clinical course. Purpose of the study: to develop diagnostic and treatment algorithm for varies CRSwNP phenotypes based on clinical and laboratory parameters. Materials and methods, CRSwNP patients were split into 3 groups: group 1 - CRSwNP without allergy and asthma group 2 - CRSwNP with allergic rhinitis and/or allergic asthma group 3 - CRSwNP with non-allergic asthma. All patients were subjected to nasal cavity endoscopy and nasal polyps biopsy, allergological examination, histological analysis of polyp stroma to detect the leukocytes infiltration and eosinophil-neutrophil index (ENI). Results, CRSwNP phenotypes show significant difference in clinical manifestations of rhinosinusitis (p0.005), eosinophil blood count (p0.001), and polyps stroma leukocytes infiltration (p0.004). At the same time, the combination of CRSwNP with allergic rhinitis, allergic and non-allergic asthma showed a more pronounced inflammatory response, which once again confirms the fact of the mutual influence of these pathological processes on each other. It was also found that the absolute eosinophil blood in peripheral blood does not correlate with the severity of eosinophilic cell infiltration degree in nasal polyps stroma, and, consequently, does not have correlate clinically relevant information on intensity of the local inflammatory response, contrary to previously proven relation between eosinophil count in blood and sputum in patients with asthma. Conclusion, Our study showed the feasibility of phenotyping CRSwNP depending on the comorbidity, which is a necessary tool in the selection of therapy in each case. Therefore, to improve the control and prevention of relapse of CRSwNP, a diagnostic and treatment algorithm for the management of patients depending on the phenotype of the disease is proposed.

Allergic asthma is an inflammatory disease involving the Th1/Th2 cell imbalance in the peripheral blood. Repeated herbal acupoint sticking (RHAS) has been used for hundreds of years in China to relieve the recurrence of allergic asthma, and it is still practiced today. Thus, we explored the effect on allergic asthma relapse and the underlying immunoregulatory mechanism in this study. Here, we enrolled 50 allergic asthma participants, and 38 of them completed the treatment and follow-up (the allergic asthma group). In addition, 13 healthy participants (the control group) were enrolled. The recurrence number of allergic asthma participants and asthma control test (ACT) were used to evaluate the effect of treatment on relieving allergic asthma recurrence. Flow cytometry was performed to analyze the levels of Th1 and Th2 cells in the peripheral blood. The serum levels of IgE, IFN-γ, and IL-4 were detected by ELISA. (1) In the allergic asthma group, compared to before the first treatment, the recurrence number of allergic asthma participants decreased and the ACT score increased at end of the last treatment, 18 and 30 weeks of the trial (P<0.05). At 18 and 30 weeks of the trial, the recurrence number of allergic asthma participants was less and the ACT score was higher than the ones from the same period last year in the allergic asthma group (P<0.05). Compared to before the first treatment, the percentage of Th1 cell did not change significantly, the percentage of Th2 cell decreased, and the Th1/Th2 cell ratio increased in the allergic asthma group by the end of the last treatment (P<0.05). Meanwhile, the release of IgE and IL-4 reduced (P<0.05), and the release of IFN-γ did not significantly change in the allergic asthma group. (2) Compared with the control group, the serum levels of IgE and IL-4 and the percentage of Th2 cell were higher, and the Th1/Th2 cell ratio was lower in the allergic asthma group (P<0.05). There was no significant difference between Th1 cell and IFN-γ before the first treatment. (3) Compared with the control group, the IgE levels and the percentage of Th2 cell were higher in the allergic asthma group (P<0.01). Simultaneously, there was no significant difference between Th1 cell, the Th1/Th2 cell ratio, and the serum levels of IFN-γ and IL-4 by the end of the last treatment. The data suggested that RHAS reduced the amount of Th2 cell and elevated the Th1/Th2 cell ratio, thereby alleviating the inflammatory responses in the allergic asthma participants.

Biomaterial implants induce a local inflammatory response. A comparison of the inflammatory cell response was made between several biomaterials commonly used as vascular prostheses. Disks of polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE), aluminum, titanium, copper, and stainless steel were surgically placed into the peritoneum of mice. Recruited macrophage and neutrophil populations were measured after recovery from the disk surface and peritoneal lavage. Following peritoneal biomaterial implants, there was no difference in total neutrophil or macrophage recruitment between mice implanted with PET, PTFE, aluminum, or titanium disks. However, there was significant attenuation of total neutrophil and macrophage recruitment to stainless steel compared with the other implants. Similarly, there was no significant difference in the percentage of leukocytes adherent to the PET, aluminum, or titanium disks. Macrophage adherence to the stainless steel disks was attenuated by 19.1%, and the number of neutrophils was attenuated by 69.1% when compared with PET implant mice. Mice implanted with copper disks universally expired. Leukocyte recruitment did not differ between PET, PTFE, aluminum, or titanium disks, suggesting that these materials stimulate similar inflammatory responses. Stainless steel disks recruited both fewer neutrophils and fewer macrophages and support lower adherence of these cells than the other biomaterials. Copper incited an overwhelming and fatal response.

Introduction: The combination of asthma and allergic rhinitis can affect the mutual encumbrance to which other pathogenetic mechanisms join, which worsen the course of both diseases. The aim of work is to analyze the features of the genotype and phenotype in patients with a co-morbidity of asthma and allergic rhinitis. Materials and methods: In order to detect the features of asthma and allergic rhinitis, 115 patients were examined. Patients were divided into two groups: the first included 58 patients with allergic asthma and allergic rhinitis co-morbidity, the second – 57 patients with non-allergic asthma morbidity. Results: For the group of patients with allergic asthma with concomitant allergic rhinitis, the first manifestation of allergy in childhood is characteristic (allergic rhinitis, hay fever, atopic dermatitis). For this group of patients characterized by a heavy family allergic history. Symptoms of allergic rhinitis aggravate the course of asthma. Characteristic correlation of symptoms of allergic rhinitis with distal obstruction and pronounced lability of bronchi. In these patients, the total increase in IgE and blood eosinophilia, in 1,5 times increased blood histamine and the level of exhaled NO2 have been increased. Also, asthma control with concomitant allergic rhinitis was significantly worse than in an isolated asthma group (p <0.05). Conclusion: The obtained data allow to distinguishing the phenotype of patients with asthma and allergic rhinitis co-morbidity.

Endothelial function remains chronically abnormal after vascular injury associated with coronary intervention. The long-term effects of drug-eluting stent (DES) on endothelial function are not known. We evaluated the endothelial-dependent vasomotor function and local release of pentraxin3 (PTX3) as a local inflammatory marker in nonrestenotic coronary arteries more than six months following DES and bare metal stent (BMS) implantation. Fifty-two patients treated six months earlier with a coronary stenting for isolated proximal left anterior descending (LAD) stenosis, with no evidence of restenosis, were studied. Twenty patients had been stented with BMS, and 32 had been with DES. Changes in diameter at distal site of the stented LAD in response to intracoronary acetylcholine (Ach) infusions (1,3,10,30 μg/min) were assessed by quantitative angiography. At the completion of the protocol, a 2mg bolus of isosorbide dinitrate (ISDN) was injected into the LAD. We also measured serum PTX3 levels sampled in coronary sinus (CS) and sinus of Valsalva (V). Results: The two groups had similar risk factors for endothelial dysfunction. The mean percent change in the diameter of the stented LAD by Ach injection was significantly more in the DES group than in the BMS group (−38.9±6.1 vs. −19.2±6.7 %, p<0.01). There was no significant difference in maximal dilation achieved by ISDN infusion between the two groups (34.6±6.6 vs. 31.2±4.6 %, NS). The translesional PTX3 gradient (CS-PTX3 minus V-PTX3) was higher in the DES group than in the BMS group (+0.11±0.05 vs. −0.01±0.05 ng/ml, p<0.01). More severe endothelial dysfunction was observed long term after DES implantation as compared to BMS. These findings were associated with an increased local inflammatory response to DES stenting.

Eosinophils are important to the pathogenesis of allergic asthma, and are increased in bronchoalveolar lavage within four hours after bronchoprovocation of allergic asthmatic patients, and remain significantly increased up to 24 hours later. While the components of human eosinophil granules have been recently isolated and purified, the mechanisms of degranulation have yet to be elucidated.We obtained blood from two volunteers who had a history of allergic rhinitis and asthma and a positive skin test (5x5mm wheal) to Alternaria and Ragweed. Eosinophils were obtained using a modification of the method described by Roberts and Gallin.

Over the past decades, the first breakthrough milestone in the treatment of severe forms of atopic dermatitis (AD) has been targeted therapy aimed at inhibiting IL-4 and IL-13. This was made possible thanks to advances in the understanding of the pathogenesis of AD, the driver of which is the Th2-type immune response, which also underlies such manifestations of atopy as bronchial asthma, allergic rhinitis, and polynosis. In the case of the Th2-type immune response, cytokines IL-4 and IL-13 are secreted, which are the main promoters of the inflammatory response in AD. Inhibition of IL-4 and IL-13 leads to the prevention of inflammation and is an effective approach to therapy. The use of therapy aimed at inhibition of cytokines allows you to effectively cope with the manifestations of severe and moderately severe blood pressure.
