ABSTRACT

ABSTRACT Objective The aim of this study was to investigate polycystic ovary syndrome (PCOS) and to explore the relationship between body fat percentage and metabolic markers. Subjects and methods Sedentary women were assigned to PCOS (N = 60) and CONTROL (N = 60) groups. Each group was subdivided into three subgroups according to body fat percentage (22-27%, 27-32% and 32-37%). The protocol consisted of assessments of glucose, insulin, androgens, follicle stimulating hormone (FSH), luteinizing hormone (LH), 17-hydroxyprogesterone (17-OHP), leptin, adiponectin, tumor necrosis factor (TNF-α) and interleukin-6 (IL-6). Results The PCOS subgroups showed higher concentrations of androgens, LH and 17-OHP. Leptin showed direct relationship with increased body fat percentage, whereas adiponectin showed the inverse effect. However, both were unaffected by PCOS. TNF-α and IL-6 were higher in PCOS women and showed a direct relationship with increased body fat percentage. Glucose showed direct relationship with body fat percentage, whereas insulin presented higher values in PCOS women and direct relationship with increased body fat percentage. Conclusions Our findings indicate that PCOS and body fat percentage directly influence concentrations of insulin, TNF-α and IL-6, whereas leptin and adiponectin are influenced only by the increase in body fat percentage in these women.

ABSTRACT

Rheumatoid arthritis (RA) is an autoimmune disease of knee joints involving pain and inflammation. Rhoifolin is a plant flavonoid known to have antioxidant and anti-inflammatory properties. This study was taken to identify the effect of rhoifolin on complete Freund's adjuvant (CFA)-induced arthritis in the rat model. Treatment with rhoifolin (10 and 20 mg/kg) showed a significant improvement in the overall health parameters such as paw edema and weight loss. This improvement in morphological parameters corroborated the findings with gross morphological changes observed in the histopathological analysis. Rhoifolin treatment also caused a significant decrease in oxidative stress, evident from changes in intracellular levels of glutathione, glutathione peroxidase, malondialdehyde, and superoxide dismutase in the articular cartilage tissue. Moreover, proinflammatory cytokines, tumor necrosis factor (TNF)-α, interleukin(IL)-1β, and IL-6 showed a significant downregulation of gene expression and intracellular protein concentration levels. The NF-κB pathway showed a significant attenuation as evident in the significant reduction in the levels of NF-κB p65 and p-IκB-α. These results indicated that rhoifolin can be a natural therapeutic alternative to the extant regimens, which include non-steroidal anti-inflammatory drugs and immunosuppressants. Additionally, the antioxidant and anti-inflammatory action of rhoifolin was probably mediated by the NF-κB pathway. However, the exact target molecules of this pathway need to be determined in further studies.

ABSTRACT

OBJECTIVE@#To study the incidence rate of non-thyroidal illness syndrome (NTIS) in critically ill children with or without sepsis and the association of NTIS with interleukin-6 (IL-6) and interleukin-10 (IL-10).@*METHODS@#A retrospective analysis was performed on the medical data of 97 children with sepsis (sepsis group) and 80 non-sepsis children with bacterial infection (non-sepsis group). The correlations of IL-6 and IL-10 with the thyroid function parameters triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH) were analyzed.@*RESULTS@#There were no significant differences in age and sex between the sepsis and non-sepsis groups (P>0.05). Compared with the non-sepsis group, the sepsis group had a significantly higher Sequential Organ Failure Assessment score, a significantly longer length of hospital stay, and a significantly higher rate of use of ventilator (P0.05), but the pooled analysis of the two groups showed that IL-6 level was negatively correlated with T3 and T4 levels (P<0.001).@*CONCLUSIONS@#Children with sepsis have a higher incidence rate of NTIS than those without sepsis. The high level of IL-6 may be associated with the development of NTIS.

ABSTRACT

OBJECTIVE@#To explore the therapeutic effect and the mechanism of the adjuvant treatment with moxibustion on coronavirus disease 2019 (COVID-19).@*METHODS@#A total of 95 patients with COVID-19 were randomly divided into a moxibustion group (45 cases) and a basic treatment group (50 cases). The routine treatment of western medicine was applied in the patients of both groups. In the moxibustion group, on the base of the treatment of western medicine, moxibustion was applied to Dazhui (GV 14), Feishu (BL 13), Qihai (CV 6) and Zusanli (ST 36), once daily and consecutively for 14 days. At the end of treatment courses, clinical symptom scores for cough, asthmatic breathing, chest oppression and short breath, as well as their remission rates were compared between the two groups before and after treatment. Before and after treatment, the white blood cell (WBC) count, the levels of c-reactive protein (CRP) and interleukin-6 (IL-6) and the absolute number of T lymphocyte subsets, i.e. , and of the peripheral blood were compared in the patients between the two groups. The principal component analysis was adopted to analyze the common data extracted from the above 10 clinical indexes variables and comprehensively evaluate the differences in the therapeutic effect of two regimens.@*RESULTS@#The clinical symptom scores were all decreased after treatment in both of the moxibustion group and the basic treatment group as compared with those before treatment (@*CONCLUSION@#On the base of the routine treatment with western medicine, moxibustion therapy supplemented relieves the clinical symptoms, reduces the levels of inflammatory indexes, i.e. IL-6 and CRP as well as improves the absolute number of peripheral T lymphocyte subsets. The clinical therapeutic effect of such regimen with moxibustion supplemented is significantly better than the simple routine treatment of western medicine.

ABSTRACT

Abstract Background Inflammation is involved in the pathophysiology of depression, and circulating inflammatory cytokines have been associated with depressive symptoms. However, measuring circulating cytokines have inherent methodological limitations. In vitro lipopolysaccharide (LPS)-stimulated intracellular cytokines (ICCs) overcome these limitations. Furthermore, because psychosocial and physiological stressors activate inflammatory responses and LPS-stimulated ICCs reflect the inflammatory responsivity of monocytes to such stressors, ICCs may reflect individual stress responsivity. Methods This cross-sectional study examined whether LPS-stimulated expression of ICCs in peripheral blood mononuclear cells (PBMCs) is a sensitive inflammation measure correlated with depressive symptoms in 180 community-dwelling older adults. We tested correlations of not only intracellular but also circulating inflammatory markers with depressive symptoms assessed using the 10-item Center for Epidemiological Studies Depression Scale (CES-D). Intracellular markers included expression of interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and both in PBMCs. Circulating markers included IL-6, TNF-α, and C-reactive protein (CRP) in plasma. Results None of the correlations were statistically significant. However, in contrast to circulating markers, the correlations of ICCs were consistently in the expected direction, i.e., higher ICC expression correlating with higher depression severity. Discussion Despite the non-significant findings, further research is required for the evaluation of LPS-stimulated ICC expression as biomarkers of depressive symptoms.

ABSTRACT

SUMMARY OBJECTIVE The aim of this study was to determine the potential association of foot pain and plasmatic adipocytes as physiological biomarkers of childhood obesity with the incidence of flatfoot in a cohort of Egyptian school children aged 6 -12 years. METHODS A total of 550 Egyptian schoolchildren (220 boys and 330 girls) aged 6-12 years were randomly invited to participate in this descriptive survey analysis. For all children, we assessed the diagnosis and severity of flatfoot as well as plasma adipocytes, as well as adiponectin, leptin, resistin, IL-6, and TNF-α, using the Dennis method and immunoassay techniques respectively. Foot pain was assessed by using a standard VAS of 100 mm and Faces Pain Scale, respectively. RESULTS Flat foot was predicted in 30.4% of school-age children, most of them showed a higher frequency of overweight (33.3%) and obesity (62.5%). Boys showed higher ranges of flat foot than girls. Foot pain significantly correlated with flat foot and obesity among the studied populations. In overweight-obese children, plasmatic adipocyte variables, as well as adiponectin, leptin, resistin, IL-6, TNF-α.; showed significant correlations with foot stance, especially in boys. Also, the studied adipocyte variables along with BMI, age, gender explained about~65% of the variance of flatfoot with pain among our school-age students. CONCLUSION Foot pain showed an association with flat foot and childhood obesity in 30.4% of school-age students (6-12 years). Foot pain was shown to correlate positively with the incidence of flat foot and changes in adiposity markers, as well as adiponectin, leptin, resistin, Il-6, TNF-α


RESUMO OBJETIVO O objetivo deste estudo foi determinar a potencial associação de dor no pé e adipócitos plasmáticos como biomarcadores fisiológicos da obesidade infantil com incidência de pé plano em uma coorte de escolares egípcios de 6 a 12 anos. MÉTODOS Um total de 550 escolares egípcios (220 meninos e 330 meninas) com idades entre 6 e 12 anos foram convidados aleatoriamente para participar desta análise descritiva. Para todas as crianças, diagnóstico e gravidade do flatfoot, bem como adipócitos plasmáticos; adiponectina, leptina, resistina, IL-6 e TNF-α; foram avaliados pelo método de Dennis e técnicas de imunoensaio, respectivamente. A dor no pé foi avaliada usando uma EVA padrão de 100 mm e a Faces Pain Scale, respectivamente. RESULTADOS O pé plano foi predito em 30,4% das crianças em idade escolar; a maioria apresentou maior frequência de sobrepeso (33,3%) e obesidade (62,5%). Os meninos apresentaram maiores faixas de pé plano do que as meninas. A dor no pé correlacionou-se significativamente com pé plano e obesidade entre as populações estudadas. Em crianças obesas com sobrepeso, variáveis adipocitárias plasmáticas; adiponectina, leptina, resistina, IL-6 e TNF-α; apresentaram correlação significativa com a postura do pé, em meninos e meninas. Além disso, as variáveis estudadas dos adipócitos, juntamente com o IMC, idade e sexo, explicaram cerca de 65% da variância do pé plano com a dor entre os nossos alunos em idade escolar. CONCLUSÃO A dor no pé mostrou associação com pé plano e obesidade infantil em 30,4% dos estudantes em idade escolar (6-12 anos). A dor no pé se correlacionou positivamente com a incidência de pé plano e a mudança nos marcadores de adiposidade; adiponectina, leptina, resistina, IL-6, TNF-α.

ABSTRACT

Abstract Introduction: Burnt sugarcane harvesting requires intense physical exertion in an environment of high temperature and exposure to particulate matter. Objective: To evaluate the effects of burnt sugarcane harvesting on rhinitis symptoms and inflammatory markers in sugarcane workers. Methods: A total of 32 male sugarcane workers were evaluated with questionnaire for rhinitis symptoms, and for inflammatory markers on peripheral blood and nasal lavage, in the non-harvesting, and 3 and 6 months into the sugarcane harvesting period. Weather data and particulate matter fine concentrations were measured in the same day. Results: The particulate matter concentrations in sugarcane harvesting were 27 (23-33 µg/m3), 112 (96-122 µg/m3), and 63 (17-263 µg/m3); 24 h temperatures were 32.6 (25.4-37.4 ºC), 32.3 (26.7-36.7 ºC) and 29.7 (24.1-34.0 ºC) and relative humidities were 45.4 (35.0-59.7%), 47.9 (39.1-63.0%), and 59.9 (34.7-63.2%) in the non-harvesting period, three and 6 months of the harvesting period. The age was 37.4 ± 10.9 years. The prevalence of rhinitis symptoms was significantly higher at 3 months of the harvesting period (53.4%), compared to non-harvesting period (26.7%; p = 0.039) and at 6 months into the harvesting period (20%; p = 0.006). Concentrations of interleukin 6 (IL-6) in nasal lavage increased after 3 months of the harvesting period compared to the non-harvesting period (p = 0.012). The presence of rhinitis symptoms, after 3 months of the harvesting period, was directly associated with blood eosinophils and inversely associated with neutrophils. Conclusions: After 3 months of work in burnt sugarcane harvesting the prevalence of rhinitis symptoms and IL-6 in nasal lavage increased. Furthermore, eosinophil counts were directly associated with the rhinitis symptoms in the period of higher concentration of particulate matter.


Resumo Introdução: A colheita de cana-de-açúcar queimada requer esforço físico intenso em um ambiente com altas temperaturas e exposição a material particulado. Objetivo: Avaliar os efeitos da colheita de cana-de-açúcar queimada nos sintomas de rinite e marcadores inflamatórios de cortadores de cana-de-açúcar. Método: Foram avaliados 32 cortadores de cana-de-açúcar do sexo masculino por meio de um questionário para sintomas de rinite, e marcadores inflamatórios em sangue periférico e lavado nasal, no período de entressafra, e em 3 e 6 meses após o início da colheita da cana-de-açúcar. Os dados climáticos e as concentrações de material particulado fino foram medidos no mesmo dia. Resultados: O material particulado fino na entressafra e em 3 e 6 meses de safra foi 27 (23-33 µg/m3), 112 (96-122 µg/m3) e 63 (17-263 µg/m3), respectivamente; a temperatura de 24 horas foi 32,6 (25,4º-37,4ºC), 32,3 (26,7º-36,7ºC) e 29,7 (24,1º-340ºC) e a umidade relativa do ar foi 45,4 (35,0%-59,7%), 47,9 (39,1%-63,0%), e 59,9 (34,7%-63,2%), na entressafra, 3 e 6 meses após o início da colheita. A idade foi de 37,4 ± 10,9 anos. A prevalência de sintomas de rinite foi significativamente maior em 3 meses da S (53,4%), comparado com a entressafra (26,7%; p = 0,039) e 6 meses da safra (20%; p = 0,006). As concentrações de interleucina 6 (IL-6) no lavado nasal aumentaram após 3 meses do início da colheita comparado com a entressafra (p = 0,012). A presença de sintomas de rinite, após 3 meses do início da colheita, foi diretamente associada com eosinófilos e inversamente associada com neutrófilos. Conclusões: Após 3 meses do início da colheita da cana-de-açúcar queimada, houve aumento na prevalência de sintomas de rinite e IL-6 em LN. Além disso, as contagens de eosinófilos foram diretamente associadas aos sintomas de rinite no período de maior concentração de material particulado.

ABSTRACT

ABSTRACT Fatigue is one of the most frequent and disabling symptoms in multiple sclerosis (MS). Central, psychological, and peripheral factors may contribute to the occurrence of fatigue. Objectives: The current study aimed to evaluate potential fatigue determinants in patients with relapsing-remitting MS with a low functional impairment. Methods: We compared inflammatory markers, respiratory pressures, disability, and quality of life in 39 relapsing-remitting MS patients with and without fatigue. Results: Patients with relapsing-remitting MS with fatigue had higher Expanded Disability Status Scale scores (p = 0.002). We observed a significant association between the results of the Guy Neurological Disability Scale, the Functional Assessment of MS Quality of Life Rating Scale and the presence of fatigue (p < 0.05). Conclusions: The degree of functional impairment is a determinant for the presence of fatigue in MS patients, but respiratory function and inflammatory markers are not.


RESUMO A fadiga é um dos sintomas mais frequentes e incapacitantes na esclerose múltipla (EM). Fatores centrais, psicológicos e periféricos podem contribuir para a ocorrência de fadiga. Objetivos: O presente estudo teve como objetivo avaliar potenciais determinantes de fadiga em pacientes com EM remitente-recorrente (EMRR) com baixo nível de incapacidade funcional. Métodos: Foram comparados marcadores inflamatórios, pressões respiratórias, incapacidade e qualidade de vida em 39 pacientes com EMRR com e sem fadiga. Resultados: Pacientes com EMRR com fadiga apresentaram maior Escala de Incapacidade Funcional Expandida (p = 0,002). Observamos uma associação significativa entre os resultados da Escala de Incapacidade Neurológica de Guy e Escala de Avaliação da Qualidade de Vida Funcional com a presença de fadiga (valores de p < 0,05). Conclusão: O grau de comprometimento funcional, mas não a função respiratória e os marcadores inflamatórios, são determinantes para a presença de fadiga em pacientes com EM.

ABSTRACT

SUMMARY BACKGROUND: There is no strong evidence on the link between inflammatory profile and pattern of drug treatment response in depressive patients that could result in Coronary Artery Disease occurrence. OBJECTIVE: This study aimed to compare the subclinical atherosclerosis markers, inflammatory profile, and BDNF production in Resistant Depression (RD) or Bipolar Affective Disorder (BAD) patients under conventional treatment. METHODS: The population evaluated was comprised of 34 RD, 43 BAD, and 41 controls. Subclinical atherosclerosis markers were evaluated using ultrasonography, tomography, and exercise stress test. Plasma concentrations of TNFα, IL-1β, IL-6, and BDNF were measured using Luminex100™. The usCRP concentration was measured using turbidimetric immunoassay. IL1B, IL6, and TNFA expression were determined using TaqMan®. For the statistical analysis, the significance level was established at p<0.05. RESULTS: Concerning subclinical atherosclerosis markers, only O2 consumption was reduced in the BAD group (p = 0.001). Although no differences were found in gene expression, BDNF and IL-1β plasma concentration was increased in the RD group (p = 0.002 and p = 0.005, respectively) even with an antidepressant treatment, which suggests that these drugs have no effect in IL-1β secretion and that the inflammasome may play a role in therapy response. CONCLUSION: Taken together, both BDNF and IL-1β plasma concentrations could be used to the early identification of RD patients.


RESUMO FUNDAMENTAÇÃO: Não há fortes evidências sobre a associação entre o perfil inflamatório e o padrão de resposta ao tratamento medicamentoso em pacientes depressivos que podem resultar em ocorrência de doença coronariana. OBJETIVO: O objetivo deste estudo foi comparar os marcadores de aterosclerose subclínica, o perfil inflamatório e a produção de BDNF em pacientes com Depressão Resistente (DR) ou Transtorno Afetivo Bipolar (BAD) sob tratamento convencional. MÉTODOS: A população avaliada incluiu 34 RD, 43 BAD e 41 controles. Os marcadores de aterosclerose subclínica foram avaliados por ultrassonografia, tomografia e teste de esforço. As concentrações plasmáticas de TNFα, IL-1β, IL-6 e BDNF foram medidas utilizando Luminex100TM. A concentração de usCRP foi medida por imunoensaio turbidimétrico. A expressão de IL1B, IL6 e TNFA foi determinada usando TaqMan®. Para as análises estatísticas, foi estabelecido o nível de significância de p < 0,05. RESULTADOS: Quanto aos marcadores de aterosclerose subclínica, apenas o consumo de O2 foi reduzido no grupo BAD (p = 0,001). Embora não tenham sido encontradas diferenças na expressão gênica, a concentração plasmática de BDNF e IL-1β foi aumentada no grupo RD (p = 0,002 e p = 0,005, respectivamente) mesmo sob tratamento antidepressivo, o que sugere que esses medicamentos não têm efeito na secreção de IL-1β e que o inflamassomo pode desempenhar um papel na resposta terapêutica. CONCLUSÃO: Juntas, as concentrações BDNF e IL-1β poderiam ser usadas para a identificação precoce de pacientes com DR.

ABSTRACT

Abstract Objective: To disclose the relationships between the anatomic features of cardiac myxomas and plasma interleukin (IL)-6 levels. Methods: Twelve patients undergoing cardiac myxoma resection at The First Hospital of Putian, Teaching Hospital, Fujian Medical University were enrolled into this study. Pre- and postoperative IL-6 levels were determined by an enzyme-linked immunosorbent assay method, and correlations between cardiac myxoma dimension or volume and plasma IL-6 levels were analyzed. C-reactive protein (CRP) levels were also evaluated. Results: IL-6 and CRP levels were significantly decreased one month after cardiac myxoma resection in comparison to preoperative values. IL-6 and CRP levels did not differ between patients with a cardiac myxoma of irregular appearance and those with a myxoma of regular gross appearance, or between patients with a pedicled or a sessile myxoma. Decrement of IL-6 of patients with irregular cardiac myxomas was much higher than that of patients with regular ones, while no intergroup difference was noted in decrement of CRP. A close direct correlation was noted between IL-6 levels and maximal dimension (length) or volume of cardiac myxomas, whereas CRP levels only correlated with maximal dimension of cardiac myxomas. Conclusion: Anatomic features of cardiac myxomas (sessile, irregular appearance, maximal dimension, and volume) could be determinants of the patients' circulating IL-6 levels. IL-6 was likely to be a more sensitive biomarker than CRP in predicting the inflammatory status of patients with cardiac myxoma. Sessile and irregular cardiac myxomas might predict more severe inflammatory conditions for their more abundant endothelial cells and IL-6 overproduction.

ABSTRACT

ABSTRACT Objective: The aim of this study was to evaluate the relationship between inflammatory cytokines, placental weight, glycated hemoglobin and adverse perinatal outcomes (APOs) in women with gestational diabetes mellitus (GDM). Subjects and methods: This was a prospective, longitudinal and observational study conducted from April 2004 to November 2005 in Bauru, Brazil. Included patients had singleton pregnancies and performed a 100 g OGTT and had the levels of C-reactive protein (CRP), interleukin (IL)-6, TNF alfa and glycated hemoglobin (HbA1c) determined at 24-28th gestation weeks. Results: A total of 176 patients were included, of whom 78 had the diagnosis of GDM (44.3%). Multivariate analysis demonstrated that HbA1c, age, body mass index (BMI) and previous history of GDM were independent predictors for GDM diagnosis. ROC curve indicated that HbA1C levels ≥ 5.1% at 24-28 weeks gestation were associated with GDM. No difference was found in IL-6, tumor necrosis factor alpha (TNF-alpha) and CRP serum levels in women with and without GDM. Multivariate analysis showed that placental weight was significantly associated with APOs (p < 0.005), with a cut-off value of 610 grams as demonstrated by the ROC curve. Conclusion: Placental weight ≥ 610 grams and HbA1C ≥ 5.1% were found to be associated with APOs and GDM, respectively, and their evaluation should be part of prenatal care routine.

ABSTRACT

Acute coronary syndromes are associated with a high prevalence of complications including heart failure (HF). The aim of this study was to investigate the association of novel biomarkers with the occurrence of post-acute myocardial infarction (AMI) HF. A prospective study was conducted with patients admitted to the emergency department with ST-segment elevation myocardial infarction (STEMI). Blood and urine samples were collected for analysis of traditional and novel biomarkers, including interleukin-6, vascular cell adhesion molecule 1 (VCAM-1), and intercellular adhesion molecule-1 (ICAM-1). We compared the levels of these biomarkers between patients with and without post-STEMI HF. A total of 48 patients were assessed, with a prevalence of males. Fifteen patients (31.2%) had post-STEMI HF. Patients with HF had higher mean values of IL-6, VCAM-1, and ICAM-1 compared to those who did not develop HF (57.06 vs 14.03 pg/mL, P=0.001; 1719.58 vs 1304.34 ng/mL, P=0.001; and 1594.20 vs 1158.74 ng/mL, P<0.001, respectively). The three biomarkers were shown to be good predictors of post-STEMI HF (IL-6: AUC 0.786, P=0.002; VCAM-1: AUC 0.797, P=0.001; and ICAM-1: AUC 0.825, P<0.0001), with the respective cutoff points being calculated based on the best sensitivity and specificity indexes (IL-6: 8.67 pg/mL; VCAM-1: 1501.42 ng/mL; and ICAM-1: 1262.38 ng/mL). Of the three biomarkers, only VCAM-1 and ICAM-1 had a direct linear association between them (r=0.470, P<0.0001). IL-6, VCAM-1, and ICAM-1 were associated with the development of new post-AMI HF symptoms, but only VCAM-1 and ICAM-1 correlated with each other, possibly because they have the same pathophysiological mechanism of action.

ABSTRACT

Abstract Serum hepcidin levels may increase in response to infection and inflammation. The present study investigated the effect of nonsurgical periodontal therapy (NSPT) on levels of serum hepcidin, inflammatory markers, and iron markers. An interventional study was conducted on 67 patients (age 30-65 years) without other diseases, except for chronic periodontitis (CP). Patients were allocated to either CP or control groups. The CP group received supragingival and subgingival scaling and root planing procedures, whereas the control group received supragingival scaling. Probing depth (PD), bleeding on probing, clinical attachment level (CAL), visible plaque index (VPI), serum hepcidin and interleukin-6 (IL-6) levels, high-sensitivity C-reactive protein (hs-CRP), hematological markers, and iron markers were measured at baseline and at 90 days after NSPT. The CP group had statistically significant lower mean values for mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) (p ≤ 0.05). The control group had statistically significant reductions in hemoglobin, hematocrit, MCV, and MCH (p ≤ 0.05). Serum hepcidin, IL-6, and erythrocyte sedimentation rate (ESR) levels were significantly decreased in both groups after NSPT. Periodontal markers were more markedly reduced in the CP group compared with the control group (p ≤ 0.05). These findings suggest that NSPT may reduce the serum levels of IL-6, hepcidin, and periodontal parameters.

ABSTRACT

The term inflammaging is now widely used to designate the inflammatory process of natural aging. During this process, cytokine balance is altered, presumably due to the loss of homeostasis, thus contributing to a greater predisposition to disease and exacerbation of chronic diseases. The aim of the study was to analyze the relationship between pro-inflammatory markers and age in the natural aging process of healthy individuals. One hundred and ten subjects were divided into 5 groups according to age (22 subjects/group). Interleukin-6 (IL-6) and tumor necrosis factor α (TNF-α) were quantified using the ELISA method. High-sensitivity C-reactive protein (hsCRP) was analyzed by turbidimetry according to laboratory procedures. The main findings of this study were: a positive correlation between hsCRP and IL-6 as a function of age (110 subjects); women showed stronger correlations; the 51-60 age group had the highest values for hsCRP and IL-6; women presented higher values for hsCRP in the 51-60 age group and higher values for IL-6 in the 61-70 age group; and men showed higher values in the 51-60 age group for hsCRP and IL-6. In conclusion, the natural aging process increased IL-6 and hsCRP levels, which is consistent with the inflammaging theory; however, women presented stronger correlations compared to men (IL-6 and hsCRP) and the 51-60 age range seems to be a key point for these increases. These findings are important because they indicate that early preventive measures may minimize the increase in these inflammatory markers in natural human aging.

ABSTRACT

The natural flavonoid glycoside baicalin (BA) produces a variety of pharmaceutical effects, particularly for psychiatric/neurological disorders. This study evaluated the behavioral and neuroprotective effects of BA in mice subjected to chronic unpredictable mild stress, a model of depression. BA (25 and 50 mg/kg) significantly increased sucrose consumption and reduced immobility times in the tail suspension and forced swim tests, demonstrating that BA alleviated depression-like behaviors. Moreover, BA reduced the levels of inflammatory cytokines, such as interleukin 1β, interleukin 6, and tumor necrosis factor α, in serum and in the hippocampus. BA also abrogated increases in NMDAR/NR2B and Ca2+/calmodulin-dependent protein kinase II, and the decrease in phosphorylated ERK and reactive oxygen species production in mice subjected to chronic unpredictable mild stress. These findings suggested that the antidepressive effects of BA are due to the regulation of an NMDAR/NR2B-ERK1/2-related pathway and inhibition of inflammatory cytokines and oxidative stress. Thus, BA represents a potential candidate drug for patients suffering from depression.

ABSTRACT

ABSTRACT Objective: To evaluate intervertebral disc levels of inflammatory factor (interleukin 6) and proteinase activity (cathepsin B) in patients with a degenerative disease and serum levels of interleukin 6, serum cathepsin B activity and hyaluronic acid biomarkers. Methods: We conducted immunohistochemistry studies of intervertebral discs to analyze interleukin 6 and cathepsin B levels of patients with degenerative disease and spine fracture (Control Group) and to measure hyaluronic acid, interleukin 6 and cathepsin B activity from sera of intervertebral disc degeneration patients, fracture patients, and healthy individuals. Results: Interleukin 6 and cathepsin B seem to be related with physiopathology of intervertebral disc degeneration, since the levels of both were higher in discs of patients with intervertebral disc degeneration. Interleukin 6 and cathepsin B do not represent good biomarkers of degenerative intervertebral disc disease, since the level of such compounds is increased in the plasma of patients with fractures. Conclusion: Hyaluronic acid can be a biomarker for intervertebral disc degeneration, because hyaluronic acid levels were higher only in sera of patients with intervertebral disc degeneration.


RESUMO Objetivo: Avaliar os níveis de fatores inflamatórios nos discos intervertebrais (interleucina 6) e proteinase (catepsina B) em pacientes com doença degenerativa de disco intervertebral, além de verificar os níveis séricos de interleucina 6, ácido hialurônico e atividade sérica da catepsina B. Métodos: Foi realizado exame imuno-histoquímica dos discos intervertebrais de pacientes com doença degenerativa e fratura da coluna (Grupo Controle) e análise do plasma de pacientes com doença degenerativa de disco intervertebral. Como controle, foram utilizados plasma de pacientes com fraturas, além de indivíduos saudáveis. Resultados: Interleucina 6 e catepsina B sugerem relação com a fisiopatologia da doença degenerativa de disco intervertebral, uma vez que os níveis de ambos foram maiores nos discos de pacientes com doença degenerativa de disco intervertebral. Interleucina 6 e catepsina B não representam bons biomarcadores da doença degenerativa do disco intervertebral, já que também encontram níveis aumentados em plasma de pacientes com fratura. Conclusão: O ácido hialurônico é um possível biomarcador de doença degenerativa de disco intervertebral, porque os níveis de ácido hialurônico foram maiores apenas em plasma de pacientes com doença degenerativa de disco intervertebral.

ABSTRACT

Abstract INTRODUCTION: Immunological control of Mycobacterium tuberculosis infection is dependent on the cellular immune response, mediated predominantly by Th1 type CD4+ T cells. Polarization of the immune response to Th2 can inhibit the host immune protection against pathogens. Patients with tuberculosis coinfected with helminths demonstrate more severe pulmonary symptoms, a deficiency in the immune response against tuberculosis, and an impaired response to anti-tuberculosis therapy. METHODS: We evaluated the cellular immune response and the impact of the presence of Ascaris lumbricoides on the immune and clinical response in pulmonary tuberculosis patients. Ninety-one individuals were included in the study: 38 tuberculosis patients, 11 tuberculosis patients coinfected with Ascaris lumbricoides and other helminths, 10 Ascaris lumbricoides patients, and 34 non-infected control individuals. Clinical evolution of pulmonary tuberculosis was studied on 0, 30, 60, and 90 days post-diagnosis of Mycobacterium tuberculosis and Ascaris lumbricoides. Furthermore, immune cells and plasma cytokine profiles were examined in mono/coinfection by Mycobacterium tuberculosis and Ascaris lumbricoides using flow cytometry. RESULTS: There were no statistical differences in any of the evaluated parameters and the results indicated that Ascaris lumbricoides infection does not lead to significant clinical repercussions in the presentation and evolution of pulmonary tuberculosis. CONCLUSIONS: The association with Ascaris lumbricoides did not influence the Th1, Th2, and Th17 type responses, or the proportions of T lymphocyte subpopulations. However, higher serum levels of IL-6 in tuberculosis patients may explain the pulmonary parenchymal damage.

ABSTRACT

Introduction: Reduction in the expression of inflammatory markers and oxidative stress associated with exercise will protect against cardiovascular complications in Diabetes Mellitus (DM). Aim: The aim of this study was evaluated cardiovascular fitness (VO2 Max), interleukin-6 (IL-6), monocyte chemo-attractant protein 1 (MCP-1) and serum lipid peroxidation (TBARS) in overweight patients with Type-1 diabetes (T1DM) participating in a lifestyle-change program. Results: 20 T1DM overweight patients (43.3 ± 13.8 years), with BMI= 29.6 ± 3.5 kg/m2 , initial HbA1c 7.9 ± 0.91% and treated with multiple insulin injections, were included in this work. The lifestyle-change program consisted of: a) walking 10,000 steps/day, b) sequence of exercises of 24 minutes, 3-5 times/week, c) ¨healthy-plate¨ (and counting carbohydrates, and d) prandial insulin as blood-glucose levels. VO2 max, HbA1c, TBARS, IL6, MCP-1 were determined before starting the lifestyle-change program. Six months of adherence later, participants showed an average number of steps of 8242 ± 1834, a significant increase in VO2 max, (33.4 ±1.3 vs 36.2 ±1.5 ml.Kg-1.min-1 p= 0.008), a significant decrease in serum MCP-1 (314 ±42 vs 235 ±43 MFI p= 0.02), and less TBARS (3.01 ±0.44 vs 2.12 ±0.22 µmol/mL p= 0.015). IL-6 and HbA1c showed no significant decrease. Conclusion: Our results showed that a 6-month systemized and simple exercise plan improves cardiorespiratory fitness (VO2 max), and reduces both circulating oxidative stress and inflammation markers in overweight patients with T1DM.


Introducción: La reducción en la expresión de marcadores inflamatorios y de estrés oxidativo asociado con el ejercicio podría proteger contra las complicaciones cardiovasculares de la diabetes mellitus (DM). Objetivo: El objetivo de este estudio fue evaluar en pacientes con DM tipo1 (DMT1) y sobrepeso, la capacidad cardiorespiratoria (VO2 Max), la expresión sérica de marcadores inflamatorios (IL-6 y MCP-1) y la peroxidación lipídica sérica (TBARS), luego de participar por 6 meses de un programa de cambios de estilo de vida. Resultados: Veinte pacientes adultos (43.3 ± 13.8 años), de ambos sexos, con un Índice de Masa Corporal de 29.6 ± 3.5 kg/m2 , HbA1c inicial de 7,9% ± 0,91, en tratamiento con inyecciones múltiples de insulina participaron del estudio. Se indicó: 1) caminar 10.000 pasos/día, 2) realizar en domicilio una secuencia de ejercicios de 20 minutos, 3-5 veces/semana, 3) plato saludable (consumo de 1 fruta antes de las 3 comidas principales), 4) Insulina prandial según glucemia y conteo de carbohidratos. Se registraron parámetros antropométricos, presión arterial, se determinó VO2 max, y se midieron los niveles séricos de HbA1c, IL6, MCP-1 y TBARs. Luego de seis meses, los participantes alcanzaron un número promedio de pasos de 8242 ± 1834 y mostraron un aumento significativo en VO2 max, (33.4 ±1.3 vs 36.2 ±1.5 ml.Kg-1.min-1 p= 0.008). Además, se encontró una disminución significativa de MCP-1 (314 ±42 vs 235 ±43 MFI p=0.02) y TBARs (3.01 ±0.44 vs 2.12 ±0.22 µmol/mL p= 0.015) en comparación con el día 0. No se observaron modificaciones en los niveles de IL-6 y HbA1c. Conclusión: Nuestros resultados demuestran que el ejercicio, implementado como un plan accesible y acompañado, es adecuado para reducir los riesgos de inflamación y estado pro-oxidativo en pacientes con DM tipo1.

ABSTRACT

SUMMARY OBJECTIVE: We conducted this study to investigate the clinical efficacy of endoscopic retrograde cholangiopancreatography (ERCP) on elder choledocholithiasis and its effects on the levels of TNF-α, IL-1, and IL-6. METHODS: Elder patients with choledocholithiasis were enrolled in this study, and according to the surgical methods, they were divided into the ERCP group and the surgical group. After treatment, we compared the efficacy of these two methods on patients, inflammatory responses indicated by the levels of TNF-α, IL-1, and IL-6, and the complications. RESULTS: No statistical significance was identified in the difference of the success rate in removal between the two groups (98% vs. 94%), but indicators of the ERCP group, including the surgical duration (28.5±12.8) min, remission duration of abdominal pain (1.2±0.2) d, recession time of jaundice (2.0±0.3) d, postoperative bedridden time (1.4±0.2) d, treatment time of the anti-infection (1.5±0.2) d, length of stay in hospital (6.5±0.3) d, levels of TNF-α (2.1±0.2) μg/L, IL-1 (6.3±0.8) μg/L, IL-6 (2.8±0.3) μg/L, and the incidence rate of complications (1.8%), were all significantly lower than those in the surgical group (p<0.05). CONCLUSION: In the treatment of choledocholithiasis, ERCP is excellent in controlling the trauma, accelerating the recovery duration, reducing the occurrence of complications and ameliorating the inflammatory responses. Thus, it is an ideal choice for choledocholithiasis.


RESUMO OBJETIVO: Realizamos este estudo para investigar a eficácia clínica da colangiopancreatografia retrógrada endoscópica (ERCP) na coledocolitíase idosa e seus efeitos nos níveis de TNF-α, IL-1 e IL-6. MÉTODOS: Pacientes idosos com coledocolitíase foram matriculados neste estudo. De acordo com os métodos cirúrgicos, eles foram divididos em grupo ERCP e grupo cirúrgico. Após o tratamento, comparamos a eficácia desses dois métodos em pacientes, respostas inflamatórias indicadas pelos níveis de TNF-α, IL-1 e IL-6 e as complicações. RESULTADOS: Não houve significância estatística na diferença da taxa de sucesso na remoção entre os dois grupos (98% versus 94%), mas indicadores do grupo ERCP, incluindo a duração cirúrgica (28,5 ± 12,8) min, duração da remissão da dor abdominal (1,2 ± 0,2) d, tempo de recessão de icterícia (2,0 ± 0,3) d, tempo pós-operatório (1,4 ± 0,2) d, tempo de tratamento da infecção (1,5 ± 0,2) d, duração da internação (6,5 ± 0,3) d, níveis de TNF-α (2,1 ± 0,2) μg / L, IL-1 (6,3 ± 0,8) μg / L, IL-6 (2,8 ± 0,3) μg / L e a taxa de incidência de complicações (1,8 %) foram todos significativamente inferiores aos do grupo cirúrgico (p<0,05). CONCLUSÃO: No tratamento da coledocolitíase, a ERCP é excelente no controle do trauma, acelerando a duração da recuperação, reduzindo a ocorrência de complicações e melhorando as respostas inflamatórias. Assim, é uma escolha ideal para a coledocolitíase.

ABSTRACT

Abstract Purpose: To evaluate if Moringa oleifera leaf aqueous extract (ME) influences the healing of skin wounds of diabetic rats. Methods: Wistar rats were used (6 rats/group). Group 1 received normal saline (NS) v.o. Group 2 received moringa extract (100mg/kg v.o) for 3 weeks. Groups 3 and 4: Streptozotocin (STZ) induced diabetes. Group 3 received NS; Group 4 received aqueous ME (100mg/kg) v.o.The wounds of groups 1 and 3 rats were topically treated with NS; wounds of groups 2 and 4 treated with 200µL of 10% ME. After anesthesia, all rats had skin square excision wounds 1.5cm2. Wound percent contractions were measured. On 10th day, blood glucose and serum cytokines were measured. Histometry of wounds was studied using ImagePro6.0 software. Results: Glycemia was significantly reduced in ME treated rats. These rats had higher percent contraction of the wounds on 2nd, 5th and 10th days, then controls (p<0.05). Diabetic rats treated with NS had TNF-α, IL-1β and IL-6 expression higher than in rats receiving ME. The histopathological score of ME treated diabetic rats (198±13.7) was significantly higher than treatment with NS (145±10.5). Conclusion: ME extract positively influenced healing of wounds in diabetic rats after systemic and topical treatment.
