Abstract Aims Evidence links markers of systemic inflammation and heart failure (HF) with ventricular arrhythmias (VA) and/or death. Biomarker levels, and the risk they indicate, may vary over time. We evaluated the utility of serial laboratory measurements of inflammatory biomarkers and HF, using time-dependent analysis. Methods and results We prospectively enrolled ambulatory patients with left ventricular ejection fraction (LVEF) ≤35% and a primary-prevention implanted cardioverter-defibrillator (ICD). Levels of established inflammatory biomarkers [C-reactive protein, erythrocyte sedimentation rate (ESR), suppression of tumourigenicity 2 (ST2), tumour necrosis factor alpha (TNF-α)] and brain natriuretic peptide (BNP) were assessed at 3-month intervals for 1 year. We assessed relationships between biomarkers modelled as time-dependent variables, VA, and death. Among 196 patients (66±14 years, LVEF 23±8%), 33 experienced VA, and 18 died. Using only baseline values, BNP predicted VA, and both BNP and ST2 predicted death. Using serial measurements at 3-month intervals, time-varying BNP independently predicted VA, and time-varying ST2 independently predicted death. C-statistic analysis revealed no significant benefit to repeated testing compared with baseline-only measurement. C-reactive protein, ESR, and TNF-α, either at baseline or over time, did not predict either endpoint. Conclusion In stable ambulatory patients with systolic cardiomyopathy and an ICD, BNP predicts ventricular tachyarrhythmia, and ST2 predicts death. Repeated laboratory measurements over a year’s time do not improve risk stratification beyond baseline measurement alone.

Introduction: World most prevalence disease, is diabetes mellitus, with countless causes, it on increasing, genetic, lifestyle, infections could all be contributors as causative agents especially type 2 diabetes mellitus, increase inflammatory biomarkers plays extremely critical and vital role in progression of type 2 diabetes mellitus. So this study aimed to assess glycated hemoglobin levels and inflammatory biomarkers among T2DM and find such correlation and compare data with healthy control. Method: Cross-sectional case control study among 100 case group T2DM and 100 healthy subjects as control group, HbA1c and inflammatory biomarkers, C-reactive protein, IL6 and TNF-alpha were measured for study groups. Enzyme linked immunoassay (ELISA) used for measurement of inflammatory biomarkers TNF-α, CRP, IL6 and Cystatin C. while HbA1c assessed by ichroma device. Result:  HbA1c, C-reactive protein, IL6 and TNF-alpha were increased among T2DM patients than healthy subjects, giving increased significant difference for each, as p value <0.05. Pearson’s correlation of HbA1c with each of measured parameters showed that HbA1c has positive correlation with inflammatory biomarkers TNF-α. (R= 0.812** P=0.00), CRP(R= 0.527** P=0.00), IL6, (R= 0.778** P=0.00) and Cystatin C (R= 0.884** P=0.00) respectively. Conclusion: higher levels of inflammatory biomarkers associate with increase with glycated hemoglobin, Improvement of glycemic control reduce risk markers for development of diabetic complications. Key words: HbA1c Levels and inflammatory biomarkers, tumor necrosis factor, interleukin 6.

AbstractBackground and aimsWhiplash Associated Disorders (WAD) are a costly health burden. The condition is characterised by sensory disturbances such as widespread hyperalgesia likely indicative of central hyperexcitability. Recently elevated levels of pro-inflammatory biomarkers have also found in acute and chronic WAD. The aim of this cross-sectional study was to investigate the relationship between inflammatory biomarkers and pain processing in people with persistent whiplash associated disorders (WAD).MethodsTwenty one participants with chronic whiplash (>3 months) were recruited. Venous blood samples were collected and assays performed for C-reactive protein (CRP) and TNF-α. Blood oxygen level-dependent (BOLD) contrast images of the brain were acquired with a Siemens 1.5T MRI scanner during repeated 24 s stimulus blocks of innocuous or painful stimuli (thumbnail pressure and cold stimulation of dorsum of hand) separated by 36 s inter-stimulus intervals. Stimulus intensities used during scanning were at the level of participants’ thresholds for moderate pain. Parameter estimates representing BOLD signal increases during painful events from each participant were tested for associations with inflammatory biomarkers.ResultsClinically relevant levels of CRP and TNF-α were found in 33% and 38% of participants. Levels of CRP showed a positive correlation with levels of cold pain activation in brain regions including the anterior insula, posterior parietal cortex, caudate and thalamus (pcorrected < 0.05). Levels of TNF-α were not related to activation levels during either noxious pressure or cold. Pressure pain activations also did not show a relationship with CRP levels.ConclusionsShared variance between inflammation and increased levels of regional pain-related activation in people with persistent whiplash symptoms is apparent for cold, but not pressure stimuli.ImplicationsThe results highlight cold pain processing as an important aspect of whiplash chronicity, although the implications of this modality-specific effect are not readily apparent.

<b><i>Introduction:</i></b> This study examined the relationship between proliferative diabetic retinopathy (PDR) and serum levels of C-reactive protein, VEGF, TNF-α, and IL-6 inflammatory biomarkers, related to the pathophysiology of diabetic retinopathy. <b><i>Methods:</i></b> This cross-sectional, case control study comprised 240 patients with type 1 diabetes (80 cases with PDR and 160 controls without diabetic retinopathy) who were matched for gender and duration of diabetes. <b><i>Results:</i></b> C-reactive protein was the only inflammatory biomarker that was positively related to PDR (OR 1.96; 95% CI 1.01–3.78, <i>p</i> = 0.0045). We also noted an association between high glycated hemoglobin levels, the use of angiotensin-converting enzyme inhibitor, low glomerular filtration rate, and PDR. <b><i>Conclusion:</i></b> Patients with higher levels of C-reactive protein are more likely to present with PDR. We did not find a link between serum levels of VEGF, TNF-α, or IL-6 and PDR. The function of inflammatory biomarkers in PDR must be addressed in further studies.

Objetivo: Avaliar alterações no perfil de biomarcadores (proteína C reativa, fator de necrose tumoral, interleucina 6 e creatinina) em pacientes com pneumonia, durante o período de internação segundo a sobrevivência ou óbito, relacionando a gravidade do quadro de pneumonia ou indicativo de desenvolvimento de doença renal aguda em pacientes com pneumonia. Método: Foi realizado um estudo prospectivo com 47 pacientes que foram internados com pneumonia, no município de Cajazeiras, PB. Foram realizadas análises laboratoriais para quantificação sérica de creatinina, proteína C reativa, IL-6 e TNF- α. Resultados: Foram analisados segundo o teste de Mann-Whitney e o teste de correlação de Spearman. Foram consideradas diferenças significativas quando p0,05. Observou-se que os níveis de creatinina, proteína C reativa, IL-6 e TNF-α estavam mais elevados no grupo dos pacientes com pneumonia que vieram a óbito.  Os pacientes com pneumonia e doença renal aguda, do grupo que foram a óbito apresentaram maiores níveis de creatinina e IL-6. Para esse o grupo, os níveis de creatinina, TNF-α e IL-6 apresentaram correlação diretamente proporcionais ao escore da escala de CURB-65. Conclusão: Sugere-se que biomarcadores inflamatórios podem ser utilizados no monitoramento de agravo no quadro clínico da doença.Palavras-chave: Creatinina. Fator de Necrose Tumoral Alfa.

A prospective study was carried out with 47 patients who were hospitalized with pneumonia in the city of Cajazeiras, Paraíba. Laboratory analyzes were performed to quantify serum creatinine, C-reactive protein, IL-6 and TNF-α. Results were analyzed using the Mann-Whitney test and the Spearman correlation test. Significant differences were considered when p0.05. It was observed that the levels of creatinine, C-reactive protein, IL-6 and TNF-α were higher in the group of patients with pneumonia who died. Patients with pneumonia and acute kidney disease from the group who died had higher levels of creatinine and IL-6. For this group, creatinine, TNF-α and IL-6 levels correlated directly proportional to the CURB-65 scale score. It is suggested that inflammatory biomarkers can be used to monitor the disease's clinical condition. Keywords: Creatinine. Tumor Necrosis Factor Alpha. Interleukin-6. Pneumonia. C-reactive protein.

AbstractIntroduction:The aim of our study was to investigate the vascular endothelial growth factor levels in joint swelling-positive and joint swelling-negative rheumatoid arthritis patients and to then examine the relationship between conventional parameters such as the erythrocyte sedimentation rate and the levels of C-reactive protein, rheumatoid factor, and anti-cyclic citrullinated protein.Methods:Fifty-nine (52 women and seven men) rheumatoid arthritis patients and 25 (20 women and five men) healthy individuals volunteered for this study. The patient group was divided into two sub-groups based on whether or not they exhibited joint swelling.Results:The levels of vascular endothelial growth factor in the joint swelling-negative group were significantly different from those in the joint swelling-positive group, but they were not different from those in the control group (p=0.001 and p=0.72, respectively). We investigated the correlation between vascular endothelial growth factor and C-reactive protein levels (r=0.37, p=0.001). We also evaluated the diagnostic adequacy of vascular endothelial growth factor and created a ROC curve. The area under the curve was calculated to be 0.767.Conclusion:Vascular endothelial growth factor is an adequate diagnostic biomarker and can successfully be used to predict the occurrence of rheumatoid synovitis based on local inflammation.

Abstract Objectives To investigate the effect of grape juice ingestion in the inflammatory process in overweight and insulin resistance women. Methods An intervention study was conducted, in which, for 4 weeks, the volunteers ingested 500 mL of grape juice daily. Blood samples were collected at baseline and 2 and 4 weeks after the beginning of the grape juice ingestion. The study population consisted of healthy women (n = 20), aged between 18 and 40 years, and body mass index classified as overweight (25–29.9 kg/m²). Lipid profile and plasma glucose, insulin, leptin, adiponectin, inflammatory biomarkers (IL-10, IL-6, TNF-α, C-reactive protein, MCP-1, VCAM-1, and ICAM-1) levels were analyzed. Food consumption was evaluated by the analysis of three 24 hours recalls collected at all times. Results The intake of grape juice promoted a significant increased (P &lt; 0.05) in plasma triacylglycerols levels after 4 weeks of ingestion in comparison to the baseline. The intervention with grape juice significantly reduced plasma sICAM-1 levels after 4 weeks in comparison to the baseline. Conclusions Grape juice reduced a biomarker related to endothelial dysfunction in overweight and insulin resistance women.
