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: 1я группа ПРС без аллергии и бронхиальной астмы (БА), 2я группа ПРС в сочетании с аллергическим ринитом (АР) и/или аллергической БА (аБА), 3я 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 эозинофильнонейтрофильного 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 эозинофильноклеточной 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 лечебнодиагностический 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 nonallergic 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 eosinophilneutrophil 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 nonallergic 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.

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.

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.

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.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

The neuropsychiatric symptoms of multiple sclerosis (MS), such as anxiety and depression, can result from disease activity itself as well as psychological reaction to an unfavorable diagnosis. Accordingly, the literature reports evidence of increased anxiety-like behavior in experimental autoimmune encephalomyelitis (EAE), an accepted MS model. Due to the recently described critical role of platelets in inflammation and autoimmune disease, we examined the relationship between platelets, inflammation, and anxiety-like behavior in EAE. In the elevated plus maze, EAE-induced C57BL/6J mice showed decreased time spent in the open arms relative to vehicle-only controls, demonstrating an increase in anxiety-like behavior. This effect occurred in the presence of platelet–neuron association, but absence of lymphocytic infiltration, in the hippocampal parenchyma. Platelet depletion at the pre-clinical disease stage, using antibody-mediated lysis prevented the EAE-induced increase in anxiety-like behavior, while no significant difference in distance moved was recorded. Furthermore, platelet depletion was also associated with reduction of the pro-inflammatory environment to control levels in the hippocampus and prevention of EAE disease symptomology. These studies demonstrate the high efficacy of a platelet-targeting approach in preventing anxiety-like symptoms and clinical manifestations of EAE and have implications for the treatment of neuropsychiatric symptoms in MS.

Objective. To determine active TGF-β1 (aTGF-β1) levels in serum, skin, and peripheral blood mononuclear cell (PBMC) culture supernatants and to understand their associations with clinical parameters in systemic sclerosis (SSc) patients.Methods. We evaluated serum samples from 56 SSc patients and 24 healthy controls (HC). In 20 SSc patients, we quantified spontaneous or anti-CD3/CD28 stimulated production of aTGF-β1 by PBMC. The aTGF-β1 levels were measured by ELISA. Skin biopsies were obtained from 13 SSc patients and six HC, and TGFB1 expression was analyzed by RT-PCR.Results. TGF-β1 serum levels were significantly higher in SSc patients than in HC (p< 0.0001). Patients with increased TGF-β1 serum levels were more likely to have diffuse subset (p= 0.02), digital ulcers (p= 0.02), lung fibrosis (p< 0.0001), positive antitopoisomerase I (p= 0.03), and higher modified Rodnan score (p= 0.046). Most of our culture supernatant samples had undetectable levels of TGF-β1. No significant difference in TGFB1 expression was observed in the SSc skin compared with HC skin.Conclusion. Raised active TGF-β1 serum levels and their association with clinical manifestations in scleroderma patients suggest that this cytokine could be a marker of fibrotic and vascular involvement in SSc.

Background:SLE is an autoimmune disease (AID) of unknown origin. Several factors can contribute to immune dysfunction in SLE.Interleukin 9 (IL9) is a newly emerging T cell-derived factor preferentially expressed by CD4+T cells: T helper 9 (Th9)IL9 targets different cell lineages, and can contribute to the development of allergic & AIDsWhether abnormal expression and secretion of IL9 are present in SLE patients (pts) still unidentified. It is also unclear whether IL9 exerts main proinflammatory or anti-inflammatory activities in SLE. T1DM is characterized by inflammation of the pancreatic islets of Langerhans. Insulitis progresses over time and β cells become destroyed then clinical DM is established. T1DM is regarded as a T cell-driven AIDObjectives:Evaluation of the expression of CD4+ IL9+ T cells & the level of IL9 in SLE pts compared to both healthy subjects & pts with another AID: T1DM.Also, to evaluate the correlation of these expressions with clinical features, laboratory parameters and SLE activityMethods:The study included: Group I 25 SLE pts fulfilling SLICC classification criteria divided into 2 subgroups (gps) according to SLE disease activity index (SLEDAI) IA: 20 pts with mild to moderate activity (<12) IB:5 pts with severe activity (>12) recruited from rheumatology clinic or internal medicine ward (Rheumatology unit), Main University Hospital, Alexandria. Group II 15 healthy individuals as a first control gp. Group III 15 pts with T1DM fulfilling the American Diabetes Association criteria as a second control gp. All pts were subjected to history taking, clinical examination,laboratory investigations: CBC,LFT,KFT,ESR,CRP,ANA,Anti-dsDNA,Th9 cell expression detection by flowcytometry and serum IL9 by ELISAResults:There was no statistical difference between all gps as regards age & sex but a significant increased ESR in SLE compared to controls & T1DM p< 0.001 p=0.001Th9 expression was highly increased in SLE pts, range 0.13-4.54% & mean ±SD=1.50 ± 1.47% than both control gps. In healthy controls Th9 ranged between 0.0-1.29% with mean 0.37 ±0.52%, while in T1DM pts ranged between 0.03 to 2.13% with mean of 0.67 ± 0.59%. A high significant difference was found between SLE pts and controls p=0.001, an insignificant rise was seen in SLE pts compared to T1DM pts p=0.157. A high significant increase in Th9 was found in severe SLE: mean of 3.74 ±1.15% than in pts with mild to moderate SLE: mean 0.94±0.88% p=<0.001IL9 level was highly increased in SLE pts: mean of 42.83± 23.98 pg/ml than both control gps. In healthy controls the mean was 8.54±13.27, while in T1DM with mean of 29.17±16.09 pg/ml. A high significant difference was found between SLE pts and normal controls p<0.001 but an insignificant rise with T1DM p=0.294. A high significant increase in IL9 in pts with severe ds compared to mild to moderate pts p<0.001.A significant direct correlation between Th9 & IL9 and SLEDAI/105 A significant direct correlation between damage index and Th9 p=0.040 but not IL9 p=0.053In SLE no significant relation between Th9 or IL9 & clinical manifestations or disease duration. A direct correlations between Th9 & ESR p=0.046 and CRP p=0.025,a significant correlation between IL9 and CRP p=0.033, no correlations between Th9&IL9 level and anti-dsDNA p=0.593& 0.4 Significant direct correlation between Th9 and IL9 in T1DM pts, still no correlation with glycemic profile. IL9 levels were significantly increased in SLE with elevated CRP p=0.033 & the % of Th9 cells were increased with elevated ESR and CRP p=0.025, 0.046Conclusion:In SLE pts; IL9 level and Th9 cells expression were significantly elevated compared to healthy controls. IL9 levels and the percentages of Th9 directly correlated with the SLE disease activity. IL9 levels also were significantly increased in T1DM pts compared to controls,but they were less expressed than in SLE. This suggests an important role of IL9 in the pathogenesis AIDs as SLEReferences:[1]Tahernia L et al. Cytokines in SLE: their role in pathogenesis of disease and possible therapeutic opportunities.
