High-sensitivity C-reactive Protein Concentrations Research Articles

Pre-pandemic leukocyte count is associated with severity of post-acute sequelae of SARS-CoV-2 infection among older women in the Women's Health Initiative.

Although dysregulated inflammation has been postulated as a biological mechanism associated with post-acute sequelae of severe acute respiratory coronavirus 2 (SARS-CoV-2) infection (PASC) and shown to be a correlate and an outcome of PASC, it is unclear whether inflammatory markers can prospectively predict PASC risk. We examined the association of leukocyte count and high-sensitivity C-reactive protein (hsCRP) concentrations, measured ~25 years prior to the coronavirus disease 2019 (COVID-19) pandemic, with PASC, PASC severity, and PASC-associated cognitive outcomes at follow-up among postmenopausal women. Using biomarker data from blood specimens collected during pre-pandemic enrollment (1993-1998) and data on 1,237 Women's Health Initiative participants who completed a COVID-19 survey between June 2021 and February 2022, we constructed multivariable regression models that controlled for pertinent characteristics. PASC status was defined according to established World Health Organization criteria. Controlling for baseline characteristics, log e -transformed leukocyte count (β = 0.27; 95% confidence interval, 0.07-0.47, P = 0.009) and leukocyte count ≥5.5 × 1,000 cells/µL (β = 0.13; 95% confidence interval, 0.02-0.23; P = 0.02) were positively associated with PASC severity, defined as the sum of PASC symptoms, but not associated with overall PASC occurrence or PASC-related cognitive outcomes. Concentration of hsCRP, available on only ~27% of participants, was not associated with any of the PASC outcomes, controlling for the same covariates. Leukocyte count, a widely available clinical marker of systemic inflammation, is an independent predictor of PASC severity in postmenopausal women. Heightened inflammation preceding SARS-CoV-2 infection may contribute to PASC development. Limited statistical power to assess hsCRP role warrants further study.

Assessment of laboratory indicators of inflammatory, infection and indicators of subclinical atherosclerosis in patients with systemic lupus erythematosus

The aim of the study was to reveal the relationship between the activity of inflammation, the infectious component, platelet function and dyslipidemia, in the development of subclinical atherosclerosis in patients with systemic lupus erythematosus (SLE).Material and methods. Fifty women with SLE at the age of 52.0 [48.0–58.0] years and disease duration – 11.5 [6.0– 22.0] years were examined. The control group consisted of 21 healthy women. The concentration of high-sensitivity C-reactive protein (hsCRP), interleukin 6 (IL-6), IgG antibodies to Chlamydia pneumonia (at IgG CP), the level of Toll-like receptor (TLR2), platelet factor 4 (PF4) and antibodies to oxidized high-density lipoproteins (at oxLDL) were determined by enzyme immunoassay. Platelet aggregation indices, lipid spectrum, intima-media thickness (IMT) of common carotid arteries were investigated.Results. A significant increase in IMT of the common carotid artery (1.00 [0.80–1.10] and 0.80 [0.70–0.90] mm, respectively; p<0.01) and TKIM of the carotid bifurcation (1.10 [1.00–1.20] and 0.80 [0.70–1.10] mm, respectively; p<0.01), increased hsCRP concentration (3.67 [2.17–5.92] and 0.74 [0.30–1.26] mg/L, respectively; p<0.01), IL-6 (1.72 [1.39–2.68] and 0.60 [0.22–0.75] pg/mL, respectively; p<0.01). Significant platelet activation was noted in SLE: significant increase in TF4 concentration (21.5 [19.80–23.28] and 18.30 [13.88–20.46] ng/mL, respectively; p<0.01), marked dyslipidemia, increased concentration of oxLDL (3.16 [1.45–4.60] and 1.39 [1.26–2.04] kp, respectively; p<0.01). At IgG CP concentration and TLR2 values in patients with SLE did not differ from controls.Conclusion. In addition to traditional risk factors for the development of cardiovascular disease, the association between SLE and subclinical atherosclerotic lesions of the vascular wall can be explained by additional risk factors – inflammation and autoimmune processes. The role of the infectious component is for further study.

Impact of PSDS Combined with Ganciclovir on Treatment and Serum C5 with Inflammation and Oxidative Stress in Serum and Tears of Herpes Simplex Keratitis Patients

Background: Herpes simplex virus (HSV) is a well-established cause of eye disease and associated blindness. It is known as herpes simplex keratitis (HSK) when the HSV invades the cornea and causes symptoms such as eye pain and dryness, lacrimation, and impaired vision. Objectives: To investigate the therapeutic effect of potassium sodium dehydroandroandrographolide succinate (PSDS) combined with ganciclovir in patients with HSK. Methods: Herpes simplex keratitis patients (n = 80) were randomized into two groups (control group and ganciclovir + PSDS group). Treatment efficacy was recorded. The changes in serum C5 and concentrations of inflammatory and oxidative stress factors in the serum and tears were compared. The correlations between changes in serum C5 concentration and changes in high-sensitivity C-reactive protein (hs-CRP) and superoxide dismutase (SOD) concentrations in serum and tears were analyzed. Results: The treatment efficacy was better in the ganciclovir + PSDS group. Serum C5 concentration was lower in the ganciclovir + PSDS group after treatment. In addition, the concentrations of hs-CRP and tumor necrosis factor-α (TNF-α) as well as malondialdehyde (MDA) and SOD in the serum and tears were also lower in the ganciclovir + PSDS group. Serum C5 concentration was positively correlated with hs-CRP concentration and negatively associated with SOD concentration. Conclusions: We found improvements in clinical symptoms of patients treated with ganciclovir + PSDS. Our results suggest that the addition of PSDS to ganciclovir treatment will effectively reduce inflammation and oxidative stress and relieve the clinical symptoms of patients with HSK.

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 evaluation of the inflammatory status and systemic antioxidant-oxidant balance of women with breast cancer during adjuvant chemotherapy.

Chemotherapy may cause systemic inflammation. Therefore, reliable markers monitoring inflammation during cancer treatment are intensively investigated. In our study, we analyzed the concentration of high-sensitivity C-reactive protein (hs-CRP) and selected oxidative stress markers, such as malondialdehyde (MDA), glutathione peroxidase activity (GPx), and total antioxidant capacity (TAC), in breast cancer women before and during adjuvant chemotherapy. The study included 90 women with breast cancer stratified according to clinicopathological and anthropometric features. Blood samples were taken before and after two cycles of adjuvant chemotherapy. During adjuvant chemotherapy, a significant increase in hs-CRP concentration was noticed in the entire group of patients with breast cancer. After division into appropriate groups, a twofold increase in hs-CRP concentration was particularly observed in patients not expressing steroid hormone receptors and those without metastases in regional lymph nodes. A significant rise in hs-CRP was observed in patients with smaller tumor sizes (2 cm ≤) and with a lower stage of disease [I-IIA according to the tumor-node-metastasis (TNM) classification]. Adjuvant chemotherapy resulted in a significant decrease in GPx activity, especially in patients diagnosed with larger (> 2 cm) and more advanced tumors (IIB-IIIC according to the TNM classification), without metastasis in regional lymph nodes, and without HER-2 expression. A significant decrease in glutathione peroxidase (GPx) activity during adjuvant chemotherapy was also observed in patients with abnormal body mass index (BMI) and body fat content. TAC and MDA values remained unchanged in the entire group of patients and individual subgroups during adjuvant chemotherapy. Our study showed that adjuvant chemotherapy causes systemic inflammation, manifested by increased hs-CRP and altered markers of oxidative stress in the blood of breast cancer patients. The severity of inflammatory processes during adjuvant chemotherapy may depend on specific characteristics of breast cancer and body composition.

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 different internal fixation devices on intertrochanteric fractures.

To analyze the postoperative recovery effects of different internal fixations on intertrochanteric fractures, so as to select the best fixation method for clinical practice. This is a retrospective analysis. A total of 100 patients with intertrochanteric fractures hospitalized at The Affiliated Tai'an City Central Hospital of Qingdao University from March 2022 to March 2024 were grouped according to the treatment method. 43 patients received intramedullary fixation in an observation group and 57 patients underwent extramedullary fixation in a control group. We collected data including operation time, total length of the surgical incision, hospitalization time, postoperative reexamination rate, occurrence of reduction loss, coxa vara, infection, non-union of fractures, and postoperative imaging of the patients. The total response rate of the observation group was 88.37%, which was statistically higher than that of the control group (85.96%, P < 0.05). The mean Harris hip joint score at six months after intervention was 88.3±5.3 in the observation group, significantly higher than 62.3±4.2 in the control group (P = 0.006). In terms of inflammatory reaction, the observation group showed significantly decreased serum concentrations of high-sensitive C-reactive protein and procalcitonin at one week after surgery compared to the control group (P < 0.001). After intervention, the observation group demonstrated significantly higher balance ability than the control group (P < 0.05). Intramedullary fixation for intertrochanteric fractures can significantly promote the postoperative functional recovery and fracture healing of patients, presenting a better fixation effect.
