Arterial hypertension (AH) is a heterogenic and multisystem disease. It has been suggested that oxidative stress (OS) and systemic non-specific inflammation may be involved in pathogenesis of cardiovascular pathology including AH. The aim of our study was to characterize the plasma C-reactive protein (CRP) level as a marker of systemic inflammation in relation to OS development (on the base of 8-isoprostane level assessment), depending on duration and degree of AH. We examined 117 persons, of which 102 patients from 30 to 65 years old (average age – 54.7 years) who had previously not been receiving regular antihypertensive therapy had I–III degrees of essential hypertension and 15 healthy persons (average age – 48.7 years). In 34 patients from this group the degree of OS activity was determined by 8-isoprostane level as the main marker of OS. The control group consisted of 10 healthy persons, by age and gender comparable with the study group. Determination of plasmatic CRP levels and the level of 8-isoprostane in the serum was performed by ELISA. The study established an increase of the plasmatic CRP levels in patients with hypertension, and a statistically significant increase of serum 8-isoprostane content in hypertensive patients compared to the control group. When assessing the relationship of 8-isoprostane and CRP content in patients with different degrees of hypertension we found that the strongest positive relationship between their levels was observed in the case of I degree hypertension. This may indicate the role of oxidative stress in the pathogenesis of hypertension as a damaging mechanism which contributes to the activation of immune mechanisms and further progression of the disease. Increased CRP and 8-isoprostane levels confirm the involvement of autoimmune mechanisms and oxidative stress in the pathogenesis of hypertension. The level of C-reactive protein is dependent on the duration of hypertension, while the 8-isoprostane levels – only on degree of hypertension. A raised level of C-reactive protein can be used as an independent marker of systemic inflammation in patients with arterial hypertension.

Abstract Objectives A tension headache is the most common type of headache, and its causes are multifactorial. A relationship has been shown between migraine headaches and neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and C-reactive protein (CRP). In this study, we investigated the NLR, PLR, and serum CRP levels in frequent episodic tension-type headache (FETTH) and chronic tension-type headache (CTTH) patients. Materials and Methods This retrospective study included 64 patients with FETTH, 80 patients with CTTH, and 60 healthy controls who were followed up in the neurology clinic. Hematological parameters were compared between the patient and control groups. Results In CTTH patients, platelets, NLR, PLR, and CRP values were statistically higher than in FETTH patients and patients in the control group. In FETTH patients, the PLR value was higher than in patients in the control group, but there was no statistically significant difference in NLR and CRP values between FETTH patients and patients in the control group. Also, there was no correlation between these values and age and gender. Conclusion Increase platelet count might have an effect on tension-type headache pathophysiology. Systemic inflammation parameters were shown to be significantly higher in CTTH patients. More comprehensive studies are needed to evaluate the effect of systemic inflammation on the chronicity of tension headaches.

Arterial hypertension is an independent predictor of acute myocardial infarction. Nowadays, plasma level of high-sensitive C-reactive protein is a marker of cardiovascular risk. The objective of the research was to evaluate plasma level of high-sensitive C-reactive protein in patients with acute myocardial infarction and arterial hypertension depending on myocardial remodeling type. Materials and methods. 130 patients with myocardial infarction (63 individuals with concomitant arterial hypertension and 67 individuals without it) were observed. Transthoracic echocardiogram was used. To evaluate plasma level of high-sensitive C-reactive protein the ELISA method was applied. Results. Plasma level of high-sensitive C-reactive protein in patients with acute myocardial infarction increased by 5.11 times compared to the control group: (10.67 [5.43; 12.89]) mg/l and (2.09 [1.40; 4.60]) mg/l, respectively (p<0.001). In myocardial infarction and arterial hypertension, this parameter increased by 6.57 times (to (13.73 [7.05; 15.17]) mg/l) (p<0.001), and by 1.27 times (p<0.05) as compared to patients without arterial hypertension. No differences in plasma level of high-sensitive C-reactive protein were detected in patients with different types of left ventricular remodeling.Conclusions. Acute myocardial infarction caused by high plasma level of high-sensitive C-reactive protein is severer in co-existent arterial hypertension. There are no differences in blood levels of high-sensitive C-reactive protein depending on the type of left ventricular remodeling.

Background: Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and oral lichen planus (OLP) is considered a premalignant disease. Objectives: This study aims at comparing the salivary levels of lactate dehydrogenase (LDH), C-reactive protein (CRP), and cancer antigen 125 (CA125) among cases with OSCC, OLP, and healthy persons. Methods: In this case-control study, salivary markers were evaluated in 55 cases (15 patients with OSCC, 20 patients with OLP, and 20 healthy persons); non-stimulated saliva samples were collected from the patients and saliva markers were measured by the enzyme-linked immunosorbent assay (ELISA) method. The data were analyzed, using SPSS 21 software and ANOVA test and P < 0.05 was regarded as significant. Results: Salivary LDH and CA125 levels were significantly higher in OSCC and OLP patients compared to the control group (P < 0.05). Salivary CRP levels were significantly higher in OSCC patients compared to OLP patients (P < 0.05). Besides, salivary CRP levels were higher in OLP subjects than in the control group, but the difference was not significant (P = 0.56). Conclusions: The identification of the salivary LDH, CA125, and CRP may provide a suitable non-invasive predictive tool for malignant changes. However, its use in clinical practice needs further research.

SummaryBackground:The objective here is to examine the role of overall oxidative stress in the etiopathogenesis of gluten-sensitive enteropathy disease and its relationship with gluten free diet and autoantibodies.Methods:Eighty gluten-sensitive enteropathy patients and 80 control group participants were included in the study. As oxidative stress parameters, we researched total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), paraoxonase-1 and arylesterase parameters in the serum samples of gluten-sensitive enteropathy patients.Results:In comparison to the control group, gluten-sensitive enteropathy patients had lower TAS, paraoxonase-1 and arylesterase levels and gluten-sensitive enteropathy patients had considerable TOS and OSI levels. In contrast, patients who agreed to the gluten free eating routine had a higher OSI proportion and patients who did not conform to the gluten free eating regimen had a lower paraoxonase-1 level. An affirming reciprocation was de tected amidst TOS and OSI proportion and gluten-sensitive enteropathy autoantibodies and C-reactive protein levels and a negative correlation was found between arylesterase level and gluten-sensitive enteropathy autoantibodies.Conclusions:We observed oxidative stress levels to be higher in gluten-sensitive enteropathy patients contrasted with the control group. Oxidative stress level showed differences in gluten-sensitive enteropathy patients depending on gluten diet content and autoantibody positivity. In point of fact, C-reactive protein and gluten-sensitive enteropathy autoantibodies are identified with oxidative anxiety parameters resulting in the possibility that oxidative stress might be successful in the gluten-sensitive enteropathy pathogenesis.

Objectives. There are limited clinical data revealing the relationship between mitral annular calcification (MAC) and systemic inflammation. The goal of the present study was to compare high-sensitivity C-reactive protein (hs-CRP) levels in patients with and without MAC and investigate the relationship between MAC and hs-CRP.Methods. One hundred patients with MAC who underwent transthoracic echocardiography (TTE) and 100 age-matched controls without MAC who underwent TTE were included in our study. Hs-CRP levels were compared between groups.Results. Prevalence of female gender, hypertension, and coronary artery disease were significantly higher in the MAC group than in the control group (64% versus 45%,P=0.007, 42% versus 28%,P=0.03and 37% versus 18%,P=0.003, resp.). On multivariate analysis, age, gender, and coronary artery disease were the only independent predictors of MAC. The levels of hs-CRP were higher in the MAC group than in the control group (2.02±0.35versus1.43±0.47 mg/dl,P<0.001). This increase in hs-CRP levels in the MAC group persisted in patients without hypertension, coronary artery disease, and in male patients when compared to the control group.Conclusions. Our study demonstrated that hs-CRP, which is a sensitive marker of systemic inflammation, increased in patients with MAC.

Актуальность. Поскольку роль эндотоксина в индукции бронхообструктивного синдрома сегодня уже не вызывает сомнений, представляется целесообразным и определение роли антиэндотоксинового иммунитета (АЭИ) в формировании различных биофенотипов хронического воспаления, которые лежат в основе особенностей течения бронхиальной астмы (БА). Цель настоящего исследования - определение роли гуморального и мукозального звеньев АЭИ и системного воспаления при различных биофенотипах воспаления у больных БА, которые могли бы быть полезны для разработки персонифицированной терапии. Материалы и методы. В исследование включены 109 больных с верифицированным диагнозом среднетяжёлой и тяжёлой бронхиальной астмы. Пациенты были разделены на 3 группы в зависимости от типа воспаления в дыхательных путях: 1-я группа - эозинофильный, 2-я группа - нейтрофильный, 3-я группа - смешанный гранулоцитарный. Гуморальное и мукозальное звенья эндотоксин-связывающих систем оценивали по уровням специфических эндотоксин-связывающих антител классов M, A, G (анти-ЭТ IgM, анти-ЭТ IgA, анти-ЭТ IgG) в периферической крови, и уровню секреторного антиэндотоксинового иммуноглобулина класса A в индуцированной мокроте. Системное воспаление оценивали по концентрации С-реактивного белка (СРБ). Результаты. При нейтрофильном и смешанном биофенотипах воспаления зарегистрированы повышенные уровни анти-ЭТ IgM и анти-ЭТ IgА в периферической крови. В то время как при эозинофильном биофенотипе воспаления не выявлено существенных различий данных показателей от контрольной группы. Концентрация анти-ЭТ IgG во всех группах больных бронхиальной астмы не отличалась от диапазона нормы. При всех биофенотипах воспаления выявлено повышение концентраций секреторного анти-ЭТ IgА и СРБ в рамках низкоинтенсивного воспаления. Наибольший уровень анти-ЭТ IgА и СРБ зарегистрирован при нейтрофильном и смешанном биофенотипах воспаления. Выявлены умеренные прямые корреляционные связи: между уровнем секреторного анти-ЭТ IgA и относительным количеством нейтрофилов в индуцированной мокроте (r = 0,469, р < 0,05); между уровнем СРБ и уровнем секреторного анти-ЭТ IgA (r = 0,427, р < 0,05). Выводы. Наиболее выраженный гуморальный и мукозальный ответ на эндотоксин и интенсивность системного воспаления при нейтрофильном и смешанном биофенотипах воспаления свидетельствуют о значительной роли ингаляционного эндотоксина в формировании тяжёлой астмы. Выявленный дисбаланс гуморального и мукозального звеньев АЭИ систем дополняет современные представления патогенеза бронхиальной астмы с различными биофенотипами воспаления, предоставляет перспективу возможности персонификации лечения и достижения контроля заболевания. Background. Since the role of endotoxin in induction of broncho-obstructive syndrome is above any doubt today, we focused on the role of anti-endotoxin immunity (AEI) in the formation of different phenotypes of chronic inflammation, which underlie characteristics of the course of asthma. The aim of this study was to determine the role of humoral and mucosal components of AEI and systemic inflammation in different inflammatory phenotypes in patients with asthma, which could be useful in developing personalized therapy. Materials and methods. The study included 109 patients with a verified diagnosis of moderate to severe asthma. All patients were divided into 3 groups depending on the type of inflammation in the respiratory tract: Group 1, eosinophilic; Group 2, neutrophilic; and Group 3, mixed granulocytic inflammation. The humoral and mucosal components of endotoxin binding systems were evaluated by levels of specific endotoxin-binding class M, A, and G antibodies (anti-ET IgM, anti-ET IgA, and anti-ET IgG) in peripheral blood and the level of secretory anti-endotoxin IgA in induced sputum. Systemic inflammation was assessed by concentration of C-reactive protein (CRP). Results. Peripheral blood concentrations of anti-ET IgM and anti-ET IgA were elevated in neutrophilic and mixed inflammatory phenotypes. At the same time, in the eosinophilic inflammatory phenotype, these indexes were not significantly different from the control group. In all groups of patients with asthma, concentrations of anti-ET IgG were similar and remained within the normal range. In all inflammatory phenotypes, concentrations of secretory anti-ET IgA and C-reactive protein were increased within the range of low-intensity inflammation. The highest levels of anti-ET IgA and CRP were found in neutrophilic and mixed inflammatory phenotypes. Levels of secretory anti-ET IgA moderately directly correlated with the relative number of neutrophilic leukocytes in induced sputum (r = 0.469, р < 0.05) and levels of CRP moderately directly correlated with levels of secretory anti-ET IgA (r = 0.427, р < 0.05). Conclusions. The most pronounced humoral and mucosal response to endotoxin and the intensity of systemic inflammation in neutrophilic and mixed inflammatory phenotypes evidenced a significant role of inhaled endotoxin in the formation of severe asthma. The observed imbalance of humoral and mucosal components in AEI systems supports modern ideas of the pathogenesis of asthma with different inflammatory phenotypes and provides a promising possibility of individualized treatment and control of the disease.

Background and Purpose: The measurement of markers of inflammation or thrombosis has been proposed as a method to improve the prediction of risk in patients with vascular disease. The role of C-reactive protein (CRP) as a novel plasma marker of atherothrombotic disease is currently under investigation. We related age and gender predilection of plasma CRP levels to first ever ischemic stroke and its role on mortality. Methods: Sixty patients with either hypertension or diabetes or both or none without thrombolysis with first ever acute ischemic stroke patients were examined. CT scan of brain was done after 24 hours of onset of symptoms to confirm the diagnosis. Plasma CRP level was determined after 12 - 72 hours range after the onset of symptoms in all CT confirmed ischemic stroke patients. This clinical study was done during June 2018 to January 2020. CRP was randomly measured in 60 age and sex matched individuals admitted in other wards of the hospital matched in all possible criteria expect the disease under study as a control group. Results: The CRP concentration in ischemic strokes is independent of infarction site, the value was more between 51-70 years of age group and almost equal in both gender. 54 of the 60 ischemic strokes studied had CRP value >6 mg/l and only 6 patients had <6 mg/l (p<0.001), chi square test value is ²=73.65 which is statistically significant. Only 7 of the 60 control group had CRP >6 mg/l. Conclusion: In this study mean C-Reactive protein levels were significantly higher in patients with ischemic stroke when compared to controls. C-reactive protein level increases as age advances. C-reactive protein is a better prognostic marker with no gender predilection and not a mortality predictor.

As a marker of systemic inflammation, raised (C-reactive protein (CRP)) concentrations which are still within the normal range have been associated with an increased inflammation of chronic renal diseases (CRD). The current study aimed to establish potential determinats of raised CRP concentrations in patients who treated in Heamodialysis room,then study the relationship between CRP& some biochemical parameters related CRD We used a CRP latex reagents Kit which is based on an immunological reaction between CRP antisera bounded to the biologically inert latex particles or with CRP in the test specimens of 19 patients with (CRD) mean age 48 years ,range = 30?65 & in 21 healthy subjects as control group their age range = 30 ?45 years. The results are classified according to visible agglutination to: 1-A positive result / is indicated by the obvious agglutination pattern of the latex, in a clear solution. 2-A negative result / is indicated by no change in the latex suspension on the test slide. Then, we correlated the results of the precipitin test with the quantitative data on C-reactive protein. This study has found that: CRP concentrations in patients with CRD were increased very clearly than normal subjects , and established that CRP concentration in male was more than in female for patients specimens. Biochemical studies have shown raising (CRP) concentration is a marker of systemic inflammation. The relation between CRP & S.creatinine ,hemoglobine ,blood sugar is negative ,while positive with blood urea . Other biochemical parameter related to CRD'' blood urea, blood creatinine & hemoglobine and blood sugar'' were assayed for both subjects in order to asses the disease by compared the results.

Abstract Background: Asthma is a chronic inflammatory lung disease and oxidative stress is an important component in airway inflammation. This study aims to investigate dynamic thiol/disulfide homeostasis in patients with asthma. Methods: A total of 103 subjects, including 56 patients with asthma and 47 healthy controls, of similar age and gender were included in the study. The native thiol, total thiol and disulfide levels and the disulfide-native thiol, disulfide-total thiol and native thiol-total thiol ratios were analyzed and compared between the asthma and control groups using a novel automatized spectrophotometric assay. Results: The levels of native thiol (p<0.001), total thiol (p<0.001) and disulfide (p<0.001) were significantly lower and the C-reactive protein (CRP) levels (p<0.001) were significantly higher in patients with asthma when compared with those in the control group. A negative correlation was detected between CRP levels and native thiol, total thiol and disulfide levels (p<0.05). A significant positive correlation was detected between forced expiratory volume in 1 s (FEV1) and forced vital capacity (FVC) levels and native thiol and total thiol levels (p<0.01). Conclusions: The thiol/disulfide homeostasis parameters may be used as novel oxidative stress markers in asthma but further studies are needed to investigate the role of thiol/disulfide homeostasis in asthma.

Objective: to evaluate the severity of immuno-inflammatory responses under stable stenocardia in patients with ischemic heart disease (IHD). Patients and intervention: the study included 83 patients suffering from IHD. Among them 30 cases were diagnosed as functional class (FC)-II stenocardia, 27 cases as FC-III stenocardia and 26 cases as FC-IV stenocardia. The control group included 25 healthy persons. For characterizing the immuno-inflammatory responses we examined the level of C-reactive protein (CRP), pro-inflammatory (IL-1b, IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines by the immunoenzymic procedure. Results: FC-II stenocardia showed normal levels of CRP and pro-inflammatory cytokines. FC-III stenocardia was associated with a moderate increase in markers of an inflammation. FC-IV stenocardia was characterized by maximum levels of CRP and pro-inflammatory cytokines. Conclusion. The intensity of immuno-inflammatory responses depends on more or less serious course of stenocardia in patients with IHD.
