High-sensitivity C-reactive Protein Concentrations Research Articles

Resistin concentrations in perivascular adipose tissue as a highly sensitive marker of smoking status in patients with advanced coronary artery disease requiring coronary artery bypass grafting.

Smoking is a significant risk factor for numerous diseases, including coronary artery disease (CAD). Chronic inflammation from smoking affects endothelial function and may alter adipokine secretion, particularly resistin, in perivascular adipose tissue (PVAT). This study investigated the association between resistin concentrations in PVAT and smoking status in CAD patients undergoing coronary artery bypass grafting (CABG). The study included 110 patients with advanced CAD scheduled for CABG. Patients were categorized into never-smokers and ever-smokers, with the latter further divided into current and past smokers. Resistin concentrations in PVAT and plasma, along with plasma interleukin-6 (IL-6) and high-sensitivity C-reactive protein (hs-CRP) concentrations, were measured using ELISA. Significant differences in PVAT resistin concentrations were observed between never-smokers and ever-smokers (p < 0.0001), as well as between never-smokers and both current (p < 0.0001) and past smokers (p < 0.0001). PVAT resistin concentrations correlated positively with the number of pack-years (p < 0.0001) and plasma resistin (p < 0.0001) and IL-6 concentrations (p < 0.0001). Plasma resistin, IL-6, and hs-CRP concentrations were higher in ever-smokers compared with never-smokers. Multiple regression analysis indicated that smoking is significantly correlated with higher PVAT resistin concentrations, with increased pack-years (p = 0.0002), higher plasma resistin concentrations (p < 0.0001), and IL-6 concentrations (p < 0.0001), all contributing to elevated PVAT resistin. Smoking status in advanced CAD patients requiring CABG is positively associated with PVAT resistin concentrations, with a clear demonstration of dose-dependency.

The PerioGene North Study Uncovers Serum Proteins Related to Periodontitis

The sequalae of periodontitis include irreversible degradation of tooth-supporting structures and circulatory spread of inflammatory mediators. However, the serum protein profile in periodontitis is not well described, which is partly attributable to the limited number of studies based on large and well-characterized periodontitis cohorts. This study aims to identify novel, circulating inflammation-related proteins associated with periodontitis within the PerioGene North case-control study, which includes 478 cases with severe periodontitis and 509 periodontally healthy controls. The serum concentrations of high-sensitivity C-reactive protein (hs-CRP) and a panel of 45 inflammation-related proteins were analyzed using targeted proteomics. A distinguishable serum protein profile was evident in periodontitis cases. The protein pattern could separate cases from controls with a sensitivity of 0.81 and specificity of 0.81 (area under the curve = 0.87). Adjusted levels for hs-CRP and 24 of the 45 proteins were different between cases and controls. High levels of hs-CRP and matrix metalloproteinase–12, and low levels of epidermal growth factor (EGF) and oxidized low-density lipoprotein receptor 1 (OLR-1) were detected among the cases. Furthermore, the levels of C-C motif chemokine–19, granulocyte colony-stimulating factor–3 (CSF-3), interleukin-7 (IL-7), and hs-CRP were significantly higher in cases with a high degree of gingival inflammation. The levels of CSF-3 and tumor necrosis factor ligand superfamily member–10 TNFSF-10 were higher in cases with many deep periodontal pockets. The PerioGene North study includes detailed clinical periodontal data and uncovers a distinct serum protein profile in periodontitis. The findings of lower EGF and OLR-1 among the cases are highlighted, as this has not been presented before. The role of EGF and OLR-1 in periodontitis pathogenesis and as possible future biomarkers should be further explored.

Differences between non-obese and obese patients with hypertension according to gender

Abstract Introduction In recent years, obesity has escalated markedly, emerging as a one of major worldwide health issue. The frequency of obesity in both adults and children is rising at an alarming rate, leading to severe consequences for public health. The World Health Organization (WHO) reports that as much as 13% of the global population is grappling with obesity. Numerous research studies have established that obesity not only heightens the risk of cardiovascular diseases (CVD) including hypertension, coronary heart disease, and heart failure, but also exacerbates complications in individuals already suffering from these conditions. Purpose The aim of this study was to retrospectively analyze the differences between non-obese and obese patients admitted to the cardiology department due to hypertension according to gender. Methods We performed a retrospective analysis of 486 medical records of patients who had been admitted to the Institute of Heart Diseases of the University Clinical Hospital in Wroclaw (Poland) between January 2017 and June 2021. The study group was divided in two ways. The division of patients was into one of two groups based on the following cut-off BMI values: non-obese (BMI &amp;lt; 30) and obese (BMI ≥ 30). The study was conducted following the principles of the Declaration of Helsinki and approved by the independent Bioethics Committee of Wroclaw Medical University, protocol no. KB-837/2022. The significance level for all statistical tests was set to 0.05. R 4.3.0. was used for computations. Results Women accounted for 53% of the study group and were significantly older than men (64.7±12.8 vs. 60.5±11.8, p=0.466). Women with obesity had significantly higher triglycerides (TG), high-sensitivity C-reactive protein and thyroid-stimulating hormone concentrations and significantly lower high-density lipoprotein (HDL) concentrations than women who were not affected by obesity. Men with obesity had significantly higher TG levels, lower HDL levels, more more frequent to have diabetes (DM) and less frequent stroke in the past compared to men without obesity. (Table 1 and 2) Conclusions This study highlights important differences between patients with hypertension without and with obesity, with notable gender differences. Women with obesity showed differences only in laboratory test results, while men with obesity showed differences in laboratory test results and comorbidities. These findings emphasize the need for gender-specific management strategies and research in hypertension and obesity, underscoring the distinct cardiovascular risks associated with obesity in both genders.

Total Gestational Weight Gain Is Explained by Leptin and Body Fat, Regardless of Pre-Pregnancy Body Mass Index and Other Adipokines, in Mexican Adolescents.

Pre-pregnancy body mass index (pBMI) is a predictor of gestational weight gain (GWG). However, other factors, such as adipokines and inflammation markers, may also be associated with GWG. The aim of the study was to determine the association of leptin, adiponectin, irisin, and C-reactive protein, with GWG in adolescents. A longitudinal study was conducted from 2018 to 2023 in adolescents with a clinically healthy pregnancy. The assessments included sociodemographic and clinical data, pBMI, percent of body fat, serum concentrations of leptin, adiponectin, irisin, and high-sensitivity C-reactive protein (hsCRP), and total GWG adequacy. Cox regression models were performed, the outcome variables were inadequate and excessive GWG. In 198 participants, being overweight/obesity was marginally associated with a protective effect against inadequate GWG (HR = 0.44, 95%CI = 0.18-1.06), regardless of maternal characteristics and adipokines. Leptin (HR = 1.014, 95%CI = 1.008-1.021), and body fat percent (HR = 1.11, 95%CI = 1.05-1.17) were associated with a higher risk of excessive GWG, independent of other maternal variables such as pBMI, while adiponectin was associated with a lower risk. These findings suggest that, in Mexican adolescents, adipose tissue and its adipokines during pregnancy may play a more significant role in the final GWG than body weight.

Biomarker for cardiorenal syndrome risk in patients with liver cirrhosis and type 2 diabetes in Saudi Arabia.

To evaluate the correlation between different attributes, levels of biomarkers, and the probability of developing cardiorenal syndrome (CRS) in patients who have been diagnosed with type 2 diabetes mellitus (T2DM) and liver cirrhosis (LC). The hypothesis suggests that liver illness may be linked to renal impairment, cardiac dysfunction, and the development of cardiorenal syndrome METHODS: The current study retrospectively assessed the medical records of patients who had LC and T2DM diagnoses and were hospitalized at Al Madina Al Munwara hospitals in 2022 and 2023. This research investigated T2DM patients with physician-confirmed to have LC. Poor glycemic control is indicated by high blood glucose and glycated hemoglobin (HbA1c) readings in research participants. High blood pressure, atherogenic plasma indicator (AIP), and obesity plagued most of these individuals. High creatinine, moderate estimated Glomerular Filtration Rate (eGFR) decline, and a modest urinary albumin-to-creatinine (UACR) rise were the most prevalent variables in LC and T2DM patients. Cardiorenal syndrome risk factors, including elevated blood pressure, triglyceride levels, body mass index (BMI), and high-sensitivity C-reactive protein (hs-CRP) concentrations, were identified through logistic regression. It has been demonstrated that the prevalence of these risk factors increases with age; women may be at a greater risk for developing CRS. Specific biomarker evaluations classified 108 (22.6%) LC and T2DM patients at high risk for chronic kidney disease (CKD), 100 (20%) at risk for cardiovascular disease (CVD), and 91 (18.2%) at risk for CRS. The current assessment included 500 patients with T2DM and LC. The risk factors for CRS identified in this study included elevated cholesterol and triglyceride levels, high BMI, and elevated blood pressure, with age being a significant factor, particularly in female patients. Early identification of these characteristics in patients with LC and T2DM could aid in mitigating the progression of chronic illnesses and their associated complications.

A meta-analysis of the association between high-sensitivity c-reactive protein level and glaucoma.

Glaucoma is the second-leading cause of blindness in the US for people over the age of 40; the most common form is primary open-angle glaucoma (POAG). It has been suggested that inflammatory markers have a role in the development and the progression of glaucoma (GL). High-sensitivity C reactive protein (HsCRP) is an inflammatory marker that has been linked to cardiovascular disease and a possible link to GL. Although a number of studies have found a link between CRP and GL; POAG, normal tension glaucoma (NTG), exfoliation glaucoma (XFG), Exfoliation syndrome (XFS), other research has shown the opposite. This systematic review is to determine the association between HsCRP and GL. A literature search was conducted using the MEDLINE database. We identified thirty-six peer-reviewed studies. Five retrospective studies were included and summed up to 164305 study participants, 161759 POAG patients, and 2546 controls. The pooled result of all studies revealed that HsCRP (SMD: 0.44 mg/dl; [95% confidence interval -0.10 to 0.99]; P = 0.11, I2 89%) concentration was not significantly higher in POAG patients compared to the healthy controls. The SMD for NTG, XFG and XFS; 0.64 mg/dl; 0.03 mg/dl, 0.03 mg/dl respectively. The pooled result revealed that HsCRP concentration was not significantly higher in POAG, NTG, XFG, and XFS. No publication bias was found using the funnel plot. The meta-analysis concluded that there is no correlation between the elevated plasma levels of HsCRP and GL. Future studies should be conducted.

Toxicological Effects of Commonly Used Mosquito Coil Smoke on Liver and Lung Function in Rats

The utilization of mosquito coils as a household-level strategy for mosquito control is widely practiced in malaria-endemic regions spanning Africa, Asia, and South America. However, the continuous application of mosquito coils has prompted significant apprehensions concerning environmental and health implications. This research aims to evaluate the potential hepatic and pulmonary toxicities associated with the inhalation of mosquito coil smoke in rat subjects over both sub-chronic and chronic durations. A questionnaire was used to make inquiries regarding the prevalent types and brands of mosquito coils employed, the manner in which they are used, the durations for which they are utilized. A total of twenty-four albino rats were categorized into three distinct groups: the control group and two exposed groups. These groups were subjected to distinct brands of mosquito coil smoke across two distinct exposure regimens – a sub-chronic exposure lasting 4 weeks and a chronic exposure spanning 12 weeks. Following the exposure periods, blood samples were collected for the analysis of serum-based and biochemical markers, including serum aspartate aminotransferase (AST), alanine aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), bilirubin, serum bicarbonate, and Lactate dehydrogenase (LDH), oxygen saturation, C-reactive protein, total protein, and microscopic analysis of lung tissue and liver tissue. The histopathological analysis of lung tissue was appropriately included. However, the analysis of liver tissue was omitted. The results demonstrated a significant elevation in the levels of these biochemical markers among the exposed rats in comparison to the control group. Concurrently, a decrease in blood oxygen saturation was noted in the exposed rats when contrasted with the control group. Conversely, the serum concentrations of high-sensitivity C-reactive protein, total protein, and alanine aminotransferase (ALT) did not exhibit notable differences in relation to the control group. Additionally, microscopic analysis of lung tissue indicated the presence of histopathological lesions in the exposed rats, suggesting a detrimental impact of mosquito coil smoke exposure in a time-dependent progression.

No Effect of High Eating Frequency Compared with Low Eating Frequency on Appetite and Inflammation Biomarkers: Results from a Randomized Crossover Clinical Trial

BackgroundEating frequency (EF) focuses on the total number of eating occasions per day and may influence metabolic health. ObjectivesWe sought to examine the effect of high compared with low EF on appetite regulation and inflammatory biomarkers among healthy adults. MethodsData are from a randomized, crossover trial (the Frequency of Eating and Satiety Hormones study). Participants (n = 50) completed 2 isocaloric 21-d study periods of low EF (3 eating occasions/d) and high EF (6 eating occasions/d) in random order with a 14-d washout period in between. Participants were free-living and consumed their own food, using study-directed, structured meal plans with identical foods and total energy in both study periods. On days 1 and 21 of each EF period, fasting blood was collected during in-person clinic visits to assess plasma concentrations of ghrelin, leptin, adiponectin, and high-sensitivity C-reactive protein (hs-CRP). Linear mixed models with EF, diet sequence, and period as fixed effects and participant as random effect were used to estimate the intervention effect. Interaction effects between EF and body fat percentage were examined. ResultsAmong the 50 participants who completed the trial, 39 (78%) were women, 30 (60%) were Non-Hispanic White, and 40 (80%) had a body mass index of <25 kg/m2, and the mean age was 32.1 y. The differences between high and low EF in fasting ghrelin (geometric mean difference: 17.76 ng/mL; P = 0.60), leptin (geometric mean difference: 2.09 ng/mL; P = 0.14), adiponectin (geometric mean difference: 381.7 ng/mL; P = 0.32), and hs-CRP (geometric mean difference: −0.018 mg/dL; P = 0.08) were not statistically significant. No significant interaction was observed between EF and body fat percentage on appetite regulation and inflammatory biomarkers. ConclusionsNo differences was observed in fasting ghrelin, leptin, adiponectin, and hs-CRP comparing high and low EF. Future studies are needed to understand the physiology of EF and appetite as they relate to metabolic health.This trial was registered at clinicaltrials.gov as NCT02392897.

ASSOCIATION OF SUBCLINICAL INFLAMMATION MARKERS WITH PRIMARY HYPERTENSION IN CHILDREN - A SYSTEMATIC REVIEW WITH META-ANALYSIS

Objective: Primary hypertension (PH) is a growing threat to children's health. The pathogenesis of this phenomenon is not fully known, and subclinical inflammation and activation of the immune system are potential explanations. This systematic review and meta-analysis aimed to systematically determine whether there is an association between low–grade inflammation markers and PH in children. Design and method: The MEDLINE, EMBASE, and Cochrane databases were searched up to March 2023, with no language restrictions, for cohort, cross-sectional, and case-control studies; additional references were obtained from reviewed articles. The included studies needed to investigate an association between any inflammation markers and PH defined by the authors. Participants of the study were children (&lt;18 years old) with PH and healthy controls. The main outcome measured was the concentration of any subclinical inflammation markers in children with PH and in healthy controls. This meta-analysis included 12 studies published between 2005 and 2022, enrolling 1220 patients (689 with PH and 531 healthy controls). The data were analyzed using Review Manager. Pooled mean difference (MD) with 95% confidence interval (95% CI) was used to assess the differences in inflammation markers levels. All analyses were based on the random-effect model. The risk of bias was assessed using the Newcastle-Ottawa Scale. Results: There was a significant difference between hypertensive and control groups in high-sensitivity C-reactive protein (hsRCP) concentration (MD: 0.07 95%CI [0.04,0.09]), intercellular adhesion molecule 1 (ICAM-1) (MD: 85.28 95%CI: [50.57-119.99]), vascular cell adhesion molecule 1 (VCAM-1) (MD: 259.78 95%CI: [22.65-496.91]), neutrophil count (MD: 0.80 95%CI [0.53-1.07]), monocyte count (MD: 0.07 95%CI: [0.02-0.12]), and neutrophil-to-lymphocyte ratio (NLR) (MD: 0.49 95%CI: [0.32-0.65]). There was no difference in terms of interleukin 6 (IL-6), lymphocyte count, platelet count, mean platelet volume (MPV), as well as in platelet-to-lymphocyte (PLR) and monocyte-to-lymphocyte (MLR) ratios. Conclusions: Some easily accessible markers of low-grade inflammation might be used as an additional tool for diagnosis and screening for hypertension in pediatric patients. These promising results should be validated in large and well-conducted studies.

Association of using enteral nutrition containing probiotics and dietary inflammatory index with inflammatory factors serum levels and gastrointestinal complications in infected patients with COVID-19

PurposeThis paper aims to examine the association between the dietary inflammatory index, the consumption of Enteral Nutrition Supplemented with probiotics with certain serum inflammation markers and gastrointestinal complications among individuals diagnosed with COVID-19.Design/methodology/approachThis cross-sectional investigation involved 100 COVID-19 patients who were admitted to intensive care units in hospitals. These patients were administered two different types of Enteral Nutrition, so the dietary inflammatory index (DII), gastrointestinal complications and some serum inflammation markers have been compared between two groups.FindingsThe mean DII scores in all patients were significantly pro-inflammatory (probiotic formula 2.81 ± 0.01 vs usual formula group 2.93 ± 0.14 p = 0.19). The probiotic formula consumption had an inverse association with High-sensitivity C-reactive Protein concentration (coef = −3.19, 95% CI −1.25, −5.14 p = 0.001) and lead to a reduction of 2.14 mm/h in the serum level of Erythrocyte sedimentation rate compared to normal formula. The incidence of diarrhea, abdominal pain and vomiting in probiotic formula patients was respectively 94%, 14% and 86% less than in usual formula patients (p = 0.05).Originality/valueIn this cross-sectional study for the first time, the authors found that probiotic formula consumption was inversely associated with serum inflammation markers and gastrointestinal complications incidence. The high DII leads to more gastrointestinal complications incidence and inflammation markers. More studies are needed to prove this relationship.

Blood Profiles of Community-Dwelling People with Sarcopenia: Analysis Based on the China Health and Retirement Longitudinal Study

Introduction: Routine blood factors can be economical and easily accessible candidates for sarcopenia screening and monitoring. The associations between sarcopenia and routine blood factors remain unclear. This study aimed to examine sarcopenia and blood factor associations based on a nation-wide cohort in China. Methods: A total of 1,307 participants and 17 routine blood indices were selected from two waves (year 2011 and year 2015) of the China Health and Retirement Longitudinal Study (CHARLS). The diagnosis of sarcopenia was based on the criteria proposed by the Asian Working Group for Sarcopenia (AWGS 2019). Generalized mixed-effects models were performed for association analyses. A logistic regression (LR) model was conducted to examine the predictive power of identifying significant blood factors for sarcopenia. Results: A higher sarcopenia risk was cross-sectionally associated with elevated blood concentrations of high-sensitivity C-reactive protein (hsCRP) (OR = 1.030, 95% CI [1.007, 1.053]), glycated hemoglobin (HbA1c) (OR = 1.407, 95% CI [1.126, 1.758]) and blood urea nitrogen (BUN) (OR = 1.044, 95% CI [1.002, 1.089]), and a decreased level of glucose (OR = 0.988, 95% CI [0.979, 0.997]). A higher baseline hsCRP value (OR = 1.034, 95% CI [1.029, 1.039]) and a greater over time change in hsCRP within 4 years (OR = 1.034, 95% CI [1.029, 1.039]) were associated with a higher sarcopenia risk. A higher BUN baseline value was related to a decreased sarcopenia risk over time (OR = 0.981, 95% CI [0.976, 0.986]), while a greater over time changes in BUN (OR = 1.034, 95% CI [1.029, 1.040]) and a smaller over time change in glucose (OR = 0.992, 95% CI [0.984, 0.999]) within 4 years were also related to a higher sarcopenia risk. LR based on significant blood factors (i.e., hsCRP, HbA1c, BUN, and glucose), and sarcopenia status in year 2015 yielded an area under the curve of 0.859 (95% CI: 0.836–0.882). Conclusion: Routine blood factors involved in inflammation, protein metabolism, and glucose metabolism are significantly associated with sarcopenia. In clinical practice, plasma hsCRP, BUN, blood sugar levels, sex, age, marital status, height, and weight might be helpful for sarcopenia evaluation and monitoring.

High hsCRP concentration is associated with acute pancreatitis in multifactorial chylomicronemia syndrome.

Multifactorial chylomicronemia syndrome (MCS) is a severe form of hypertriglyceridemia (hyperTG) associated with an increased risk of acute pancreatitis (AP). However, the risk of AP is very heterogenous in MCS. Previous studies suggested that inflammation might promote disease progression in hyperTG-induced AP. To determine if low-grade inflammation is associated with AP in MCS. This study included 102 subjects with MCS for which high-sensitivity C-reactive protein (hsCRP) concentration was measured at their first visit at the Montreal Clinical Research Institute. MCS subjects with a previous history of AP had a significant higher hsCRP concentration (4.62 mg/L vs. 2.61 mg/L; p=0.003) and high hsCRP concentration (≥3mg/L) was independently associated with AP prevalence (p<0.05). Up to 64% of the variability in AP prevalence was explained by the maximal TG concentration, hsCRP concentration, the presence of rare variants in TG-related genes, and fructose intake based on a stepwise multivariate regression model (p<0.0001). This retrospective study showed for the first time that hsCRP concentration is strongly associated with AP prevalence in MCS. It also suggests that low-grade inflammation may be a driver of AP in severe hypertriglyceridemia. Prospective studies could help determine the causality of this association and assess whether medication known to reduce low-grade inflammation could help prevent AP in individuals with severe hypertriglyceridemia.

Vitamin D Status and Reference Intervals Measured by Liquid Chromatography-Tandem Mass Spectrometry for the Early Adulthood to Geriatric Ages in a South Korean Population during 2017-2022.

This study aimed to describe the latest 25-hydroxyvitamin D (25(OH)D) status of the South Korean population aged ≥ 20 years using 25(OH)D concentrations measured by liquid chromatography-tandem mass spectrometry and to determine the factors associated with total 25(OH)D concentrations. This cross-sectional, retrospective study consecutively selected 119,335 subjects with a median age of 57 (20-101) years who underwent health checkups among 13 Korean cities during 2017-2022. The total 25(OH)D concentration was 54.5 ± 24.0 nmol/L (mean ± SD). The 7.6%, 47.5%, and 82.9% of participants had 25(OH)D less than 25, 50, and 75 nmol/L, respectively. The prevalence of 25(OH)D deficiency (<25 nmol/L) was higher in females than in males (8.9% vs. 6.1%) and varied between age groups, decreasing in older subjects. Those aged 20-29 years had the highest prevalence of 25(OH)D deficiency (23.0% in females and 20.1% in males), which also varied between cities. In the adjusted model, female sex, older age, summer and autumn seasons, lower body mass index (<25 kg/m2), and lower high-sensitivity C-reactive protein concentration (<1 mg/L) were associated with higher total 25(OH)D concentrations. This study could provide an exact understanding of the status of vitamin D and help devise strategies to prevent vitamin D deficiency among the Korean population.

Changes in fibrin clot properties in patients after Roux-en-Y gastric bypass surgery

BackgroundObesity is a complex condition associated with prothrombotic fibrin networks that are resistant to fibrinolysis. Altered fibrin clot properties enhance cardiovascular risk and associate with a poorer prognosis following acute ischemic events. Bariatric surgery is commonly employed to improve cardiometabolic outcomes in individuals with obesity. However, the effects of this surgical intervention on fibrin clot properties have not been comprehensively studied. ObjectivesTo examine fibrin clot and lysis parameters in Roux-en-Y gastric bypass (RYGB) patients before and after surgery. MethodsThe fibrin clot properties of 32 individuals living with obesity before and 9 months after RYGB surgery were determined using turbidimetric analysis. Correlation and regression analyses were used to identify relationships between clot properties and anthropomorphic and clinical measures. ResultsRYGB surgery resulted in a significant reduction in adiposity-associated anthropometric measures as well as improvements in glycemia and lipid profile. Clot maximum absorbance was reduced from 0.43 ± 0.11 at baseline to 0.29 ± 0.10 at 9 months postsurgery (P < .0001), while fibrin clot lysis time failed to show a difference. The change in maximum absorbance was not caused by alterations in fibrinogen levels, while plasminogen activator inhibitor-1 concentration was significantly increased after surgery from 10,560 ± 6681 pg/mL to 15,290 ± 6559 pg/mL (P = .009). Correlation and regression analyses indicated that maximum absorbance was influenced by markers of adiposity as well as glycated hemoglobin and high-sensitivity C-reactive protein concentrations. ConclusionRYGB surgery led to a decrease in the maximum absorbance of the fibrin clot. Values of maximum absorbance were associated with measures of glycemic control and inflammation. In contrast to previous reports, fibrin clot lysis time was not affected after surgery.

Haplotype of the Lipoprotein(a) Gene Variants rs10455872 and rs3798220 Is Associated with Parameters of Coagulation, Fibrinolysis, and Inflammation in Patients after Myocardial Infarction and Highly Elevated Lipoprotein(a) Values.

Lipoprotein(a) (Lp(a)) is an independent risk factor for future coronary events. Variants rs10455872 and rs3798220 in the gene encoding Lp(a) are associated with an increased Lp(a) concentration and risk of coronary artery disease. We aimed to determine whether in high-risk coronary artery disease patients these two genetic variants and the kringle IV type 2 (KIV-2) repeats are associated with impairment of inflammatory and hemostatic parameters. Patients after myocardial infarction with elevated Lp(a) levels were included. Blood samples underwent biochemical and genetic analyses. In carriers of the AC haplotype, the concentrations of tumor necrosis factor (TNF)-α (4.46 vs. 3.91 ng/L, p = 0.046) and plasminogen activator inhibitor-1 (PAI-1) (p = 0.026) were significantly higher compared to non-carriers. The number of KIV-2 repeats was significantly associated with the concentration of high-sensitivity C-reactive protein (ρ = 0.251, p = 0.038) and overall fibrinolytic potential (r = -0.253, p = 0.038). In our patients, a direct association between the AC haplotype and both TNF-α and PAI-1 levels was observed. Our study shows that the number of KIV-2 repeats not only affects proatherosclerotic and proinflammatory effects of Lp(a) but is also associated with its antifibrinolytic properties.

Effect of preoperative intensive statin on the efficacy and inflammatory response of acute ST-segment elevation myocardial infarction after emergency percutaneous coronary intervention.

It was to explore the application value of individualized nursing oriented by solution-focused nursing mode in postoperative nursing of patients with pelvic fractures. 90 patients with ST-segment elevation myocardial infarction (STEMI) undergoing emergency percutaneous coronary intervention (PCI) were enrolled. They were randomly grouped into a control group and an experimental group, with 45 cases in each group. Patients in the general group were treated with conventional treatment, and patients in the enhancement group were treated with high-dose rosuvastatin based on conventional treatment. The experimental group was compared for indicators such as serum inflammatory factors, cardiac function, overall efficacy, and follow-up prognosis before and after the operation. After treatment, the total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in the enhancement group were better as against the control group (P<0.05). Through treatment, the concentration of high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in the enhancement group was lower compared to the general group. The total effective rate of the enhancement group (95.56%) was higher relative to the general group (86.67%) (P<0.05). In patients with STEMI, preoperative intensive statin therapy can improve the efficacy of PCI, and reduce the inflammatory response and the incidence of cardiovascular events.

The Relationship of Inflammatory Chemokine, CXCL12, with NT-proBNP: A Marker of Congestive Heart Failure in Rheumatoid Arthritis Patients

Background: Cardiovascular disease (CVD) is the most considerable long-term outcome of rheumatoid arthritis (RA) and the leading cause of premature death in RA patients. The pathogenesis of CVD in RA is largely determined by persistent systemic inflammation and its underlying factors, including chemokines. In this regard, C-X-C motif chemokine ligand 12 (CXCL12) has a crucial role in the CVD and RA pathogenesis. For the first time, plasma CXCL12 was related to conventional CV risk and well-established cardiac biomarkers in RA patients. Methods: This study was conducted on 30 RA patients who have been newly diagnosed, 30 under-treatment RA patients, and 30 healthy subjects. The plasma levels of CXCL12 and N-terminal pro-B-type natriuretic peptide (NT-ProBNP) were measured using the enzyme-linked immunosorbent assay (ELISA) technique. The high sensitivity C-reactive protein (HS-CRP) concentration was evaluated in plasma samples using the ADVIA 1800 Clinical Chemistry System based on the latex-enhanced immunoturbidimetric assay. The CVD risk was measured by calculating the Framingham risk score (FRS) and systematic coronary risk evaluation (SCORE). Results: The mean FRS and plasma concentration of high-density lipid (HDL), NT-proBNP, and HS-CRP were significantly different between the three groups (P = 0.029, P &lt; 0.001, P = 0.016, P &lt; 0.001, respectively). A significant positive correlation was found between CXCL12 with disease activity score-28 (DAS-28) (P = 0.024, r = 0.293) and NT-proBNP (P &lt; 0.0001, r = 0.570) in the patients’ group. Conclusions: Based on the results, there was a significant relationship between the inflammatory mediator CXCL12 and a well-known cardiac biomarker, NT-proBNP.

Elevated high sensitive C-reactive protein in fibromyalgia

IntroductionFibromyalgia syndrome (FMS) is a complex chronic pain condition characterized by widespread pain and tenderness, fatigue, and sleep disturbances. Currently, factors contributing to FMS are considered to be multifactorial, and the involvement of inflammatory processes is a question of debate.ObjectiveThe aims of this study were (1) to assess whether serum concentrations of high-sensitivity C-reactive protein (hsCRP) differ between individuals diagnosed with FMS and pain-free controls, (2) to determine whether these differences are associated with clinical symptoms, and (3) to explore whether the observed differences can be explained by specific covariates such as age, weight, and smoking status.MethodsAn ANOVA was applied to identify differences of hsCRP levels between FMS and pain-free controls and an analysis of covariance (ANCOVA) was performed to investigate the dependencies of hsCRP with respect to covariates. To assess the reliability of our findings, we also utilized a Bayesian robust estimation model to determine the level of confidence associated with our results.ResultsThe results showed that individuals with FMS had higher hsCRP levels compared to healthy controls [F(1,106) = 8.802, p &amp;lt; 0.001] and that higher hsCRP levels were significant correlated with a higher symptom burden (r = 0. 287, p = 0.008) and more tender points (r = 0.307, p = 0.005). Further, hsCRP levels were significantly associated with weight (η2 = 0.154, p &amp;lt; 0.001), but independent of age (η2 = 0.005, p = 0.42), smoking status (η2 = 0.002, p = 0.623), or gender (η2 = 0.0045, p = 0.437), which resulted in an insignificant group effect between FMS and controls (η2 = 0.029, p = 0.052), even after controlling for covariates.ConclusionIn conclusion, this study provides evidence that sub-inflammatory processes correlate with clinical symptoms, which can be partly attributed to differences in weight, but cannot be fully explained by them. Further research is needed to elucidate the mechanisms underlying the association between hsCRP and FMS and to explore the potential therapeutic implications of targeting hsCRP in the management of FMS.

Platelet-to-lymphocyte ratio and serum hsCRP levels in third trimester and adverse pregnancy outcomes in women with gestational diabetes mellitus

Gestational diabetes mellitus (GDM) is a major complication of pregnancy. GDM is associated with a higher risk of adverse pregnancy outcomes (APO). The purpose of this study was to assess the association between third-trimester platelet to lymphocyte ratio (PLR) and high-sensitivity C-reactive protein (hsCRP) concentration and the risk of APO in GDM pregnant women. This study selected 406 non-elderly gestational diabetes patients diagnosed in the Renmin Hospital of Wuhan University from May 2021 to February 2023 as the research objects. According to the presence or absence of APO, they were divided into an APO group (n = 171) and a non-APO group (n = 235). Logistic regression model to evaluate the correlation between PLR and hsCRP and APO in women with GDM; Restricted cubic spline analyses was used to explore nonlinear correlations between PLR or hsCRP and the risk of APO; ROC curve analysis of the diagnostic performance of PLR and hsCRP for APO in women with GDM. APO occurred in 171 of the 406 included participants. Compared with the non-APO group, patients in the APO group had higher PLR and hsCRP levels. The incidence of APO was positively associated with PLR and the hsCRP level in each logistic regression model (P < 0.05). After adjusting for all the risk factors included in this study, restricted cubic spline analyses found that the PLR and the hsCRP level were positively associated with the risk of APO. The levels of PLR and hsCRP in the third trimester are related to the occurrence of APO in women with GDM, and high levels of PLR and hsCRP may indicate the occurrence of APO.

Postprandial Triglyceride-Rich Lipoproteins-Induced Lysosomal Dysfunction and Impaired Autophagic Flux Contribute to Inflammation in White Adipocytes

BackgroundObesity and postprandial hypertriglyceridemia, characterized by an increase in triglyceride-rich lipoproteins (TRLs), cause chronic low-grade inflammation. It is unclear how postprandial TRLs affect inflammation in white adipocytes. ObjectivesThe objectives of the study were to explore the inflammatory response of postprandial TRLs in white adipocytes and investigate the possible mechanism. MethodsWe measured postprandial triglyceride (TG) and high-sensitivity C-reactive protein (hsCRP) concentrations in 204 recruited subjects and treated white adipocytes from mice with postprandial TRLs from above patients with hypertriglyceridemia. ResultsSerum hsCRP concentrations and BMI were positively related to TG concentrations in the postprandial state. Postprandial TRLs increased mRNA and protein expression of inflammatory factors, including interleukin-1β, via the NOD-like receptor protein 3 (NLRP3)/Caspase-1 pathway, and impaired autophagy flux in white adipocytes of mice. TRLs also induced lysosomal damage as evidenced by the reduced protein expression of lysosome-associated membrane proteins-1 and Cathepsin L. Inhibition of Cathepsin B, NLRP3, and mTOR signaling improved autophagy/lysosome dysfunction and inhibited the activation of the NLRP3/Caspase-1 pathway and inflammatory factors induced by TRLs in white adipocytes. ConclusionsOur results suggest that postprandial hypertriglyceridemia causes chronic inflammation in adipocytes through TRL-induced lysosomal dysfunction and impaired autophagic flux in an mTOR-dependent manner.
