Significant Reduction In C-reactive Protein Research Articles

Abstract 4131381: Comparison of Dietary Macronutrient Interventions for Weight and Cardiovascular Risk Factor Reduction: A Systematic Review and Network Meta-analysis of Randomized Controlled Trial

Background: Dietary interventions play a crucial role in weight management and reducing cardiovascular risk factors. Our study aims to compare the effectiveness of four dietary macronutrient interventions on weight loss and cardiovascular (CV) risk factor reduction through a systematic review and network meta-analysis. Methods: We conducted a comprehensive literature search on PubMed, Scopus, Embase, and Cochrane Library up till May 2024 to identify randomized controlled trials (RCTs) comparing four macronutrient dietary interventions including Mediterranean Diet (MD), Keto, Dietary Approaches to Stop Hypertension (DASH), and Intermittent Fasting (IF) with study period ≥ 6 months or 24 weeks. The primary outcomes of interest were weight loss, systolic blood pressure (SBP), Diastolic blood pressure (DBP), Body Mass Index (BMI), High density lipoprotein (HDL), Low density Lipoprotein (LDL), cholesterol levels and C-reactive protein (CRP) levels. Outcomes were reported as standard mean difference (SMD). Results: Our analysis identified 50 studies enrolling 5368 patients (MD=3554; DASH=838; Keto=206; IF=770). Regarding BP outcome, MD and DASH had significant reduction in SBP and DBP respectively (MD [SBP]: -0.76 mmHg vs DASH [DBP]: -1.92 mmHg) respectively. In contrast, IF showed a significant rise in SBP (0.87). MD participants also had significant weight loss (-1.06 kg) and a moderate decrease in BMI (-0.79) when compared with other diets. Furthermore, IF, keto, and MD showed moderate increase in HDL levels (0.61, 0.77 and 0.33) respectively. In contrast, DASH resulted in a moderate decline in HDL levels (-0.92). IF and MD resulted in modest decline in LDL levels (-0.45 and -0.42) respectively. In contrast, Keto demonstrated non-significant rise in LDL (0.35). DASH showed a significant decrease in triglycerides (-3.02). Lastly, MD demonstrated a significant reduction in CRP (-0.89). Conclusions: MD and DASH were superior to other dietary interventions in terms of weight loss and CV risk factors. Further research is required to tailor specific types of dietary interventions and assess their long-term efficacy on weight loss and CV risk reduction.

GLP-1 receptor agonists as promising anti-inflammatory agents in heart failure with preserved ejection fraction.

Heart Failure with Preserved Ejection Fraction (HFpEF) represents a significant challenge in modern cardiovascular medicine, characterized by diastolic dysfunction and a chronic pro-inflammatory milieu. The high prevalence of comorbidities such as diabetes, visceral obesity, and aging, which contribute to systemic inflammation, plays a pivotal role in the pathogenesis and progression of HFpEF. Glucagon-Like Peptide-1 Receptor Agonists (GLP-1 RAs), a class of glucose-lowering drugs, have demonstrated a wide range of pleiotropic effects that extend beyond glycaemic control. These effects include the reduction of inflammation and oxidative stress, vasodilation, decreased arterial stiffness, and a reduction in myocardial fibrosis-key factors in the pathophysiology of HFpEF. Recent evidence from the STEP-HFpEF and STEP-HFpEF-DM trials provides the first robust data supporting the efficacy of GLP-1 RAs, specifically semaglutide, in improving the quality of life in obese patients with HFpEF. These trials also demonstrated a significant reduction in C-Reactive Protein (CRP) levels, reinforcing the hypothesis that suppressing the pro-inflammatory state may yield substantial clinical benefits in this patient population. These findings suggest that GLP-1 RAs could play a crucial role in the management of HFpEF, particularly in patients with obesity, by targeting the underlying inflammatory processes and contributing to better overall cardiovascular outcomes.

Impact of Omega-3 Fatty Acid Supplementation in Parenteral Nutrition on Inflammatory Markers and Clinical Outcomes in Critically Ill COVID-19 Patients: A Randomized Controlled Trial.

The heightened inflammatory response observed in COVID-19 patients suggests that omega-3 fatty acids (O3FA) may confer anti-inflammatory benefits. This randomized, double-blind, single-center clinical trial aimed to evaluate the effect of O3FA supplementation in parenteral nutrition (PN) on inflammatory markers in COVID-19 patients admitted to the intensive care unit (ICU). A total of 69 patients were randomized into three groups: one received standard lipid emulsion, and two received O3FA (Omegaven®) at doses of 0.1 g/kg/day and 0.2 g/kg/day, respectively, in addition to Smoflipid®. The primary outcomes measured were serum levels of C-reactive protein (CRP) and interleukin-6 (IL-6) on days 1, 5, and 10 of PN initiation. Secondary outcomes included additional inflammatory markers (TNF-α, IFN-γ, IL-1Ra, CXCL10), hepatic function, triglyceride levels, and clinical outcomes such as mortality and length of ICU and hospital stay. Results indicated a significant reduction in CRP, IL-6, and CXCL10 levels in the group receiving 0.1 g/kg/day O3FA compared to the control. Additionally, the higher O3FA dose was associated with a shorter ICU and hospital stay. These findings suggest that O3FA supplementation in PN may reduce inflammation and improve clinical outcomes in critically ill COVID-19 patients.

The Impact of Exercise on C-reactive Protein Levels in Hypertensive Patients: A Systematic Review.

Hypertension, defined as persistently elevated blood pressure, is a prevalent chronic condition and a significant global health issue, closely linked to cardiovascular complications, with inflammation being one of the underlying mechanisms. In hypertensive patients, C-reactive protein (CRP), an inflammatory marker, is often elevated and associated with increased cardiovascular risk. Alongside pharmacotherapy, exercise is recommended as a non-pharmacological approach to managing hypertension, with evidence suggesting that exercise can also reduce inflammation. This study examines the impact of exercise on CRP levels in hypertensive patients. Fourteen studies focusing on exercise interventions and physical fitness related to CRP in individuals with high blood pressure were identified through an extensive search of PubMed, PubMed Central, ScienceDirect, Cochrane Library, and Google Scholar. The findings indicated that most studies involving aerobic exercise consistently demonstrated reductions in CRP levels among hypertensive patients, with significant effects observed under supervised conditions, and additional benefits seen when combined with dietary control. Resistance training showed mixed results, with significant reductions in CRP observed primarily in longer-term interventions. Combined exercise training, incorporating both aerobic and resistance elements, effectively reduced CRP levels and improved cardiovascular health markers. Physical fitness assessments, such as a bicycle exercise test to exhaustion, revealed a relationship between physical fitness and decreased CRP levels. Therefore, regular, consistent aerobic and combined training, as well as prolonged resistance exercise, significantly reduce CRP levels in hypertensive patients, highlighting exercise's role as a non-pharmacological strategy for managing hypertension through the reduction of inflammation. Further research is essential to validate these findings and investigate the underlying mechanisms and differential effects of various exercise modalities.

Dapagliflozin, inflammation and left ventricular remodelling in patients with type 2 diabetes and left ventricular hypertrophy

Background and AimsSodium-glucose co-transporter 2 (SGLT2) inhibitors have beneficial effects in heart failure (HF), including reverse remodelling, but the mechanisms by which these benefits are conferred are unclear. Inflammation is implicated in the pathophysiology of heart failure (HF) and there are some pre-clinical data suggesting that SGLT2 inhibitors may reduce inflammation. There is however a lack of clinical data. The aim of our study was to investigate whether improvements in cardiac remodelling caused by dapagliflozin in individuals with type 2 diabetes (T2D) and left ventricular hypertrophy (LVH) were associated with its effects on inflammation.MethodsWe measured C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), interleukin 6 (IL-6), and interleukin 10 (IL-10) and neutrophil-to-lymphocyte ratio (NLR) in plasma samples of 60 patients with T2D and left ventricular hypertrophy (LVH) but without symptomatic HF from the DAPA-LVH trial in which participants were randomised dapagliflozin 10 mg daily or placebo for 12 months and underwent cardiac magnetic resonance imaging (CMR) at baseline and end of treatment. The primary analysis was to investigate the effect of dapagliflozin on inflammation and to assess the relationships between changes in inflammatory markers and LV mass and global longitudinal strain (GLS) and whether the effect of dapagliflozin on LV mass and GLS was modulated by baseline levels of inflammation.ResultsFollowing 12 months of treatment dapagliflozin significantly reduced CRP compared to placebo (mean difference of -1.96; 95% CI -3.68 to -0.24, p = 0.026). There were no significant statistical changes in other inflammatory markers. There were modest correlations between improvements in GLS and reduced inflammation (NLR (r = 0.311), IL-1β (r = 0.246), TNF-α (r = 0.230)) at 12 months.ConclusionsDapagliflozin caused a significant reduction in CRP compared to placebo. There were correlations between reductions in inflammatory markers including IL-1β and improvements in global longitudinal strain (but not reduced LV mass). Reductions in systemic inflammation might play a contributory role in the cardiovascular benefits of dapagliflozin.Trial registrationClinicaltrials.gov NCT02956811 (06/11/2016).

Liraglutide for Lower Limb Perfusion in People With Type 2 Diabetes and Peripheral Artery Disease

Peripheral artery disease (PAD) in diabetes may lead to diabetic foot ulcer and lower-extremities amputation. Glucagon-like peptide 1 receptor agonists have proven cardiovascular benefits in trials of people with type 2 diabetes at high cardiovascular risk. To examine the effect of liraglutide on peripheral perfusion measured as peripheral transcutaneous oxygen pressure (TcPo2) in individuals with type 2 diabetes and PAD. This open-label randomized clinical trial was conducted between February 1, 2021, and June 30, 2022, with a final follow-up on December 30, 2022, at University of Campania "Luigi Vanvitelli," Naples, Italy. Fifty-five individuals with type 2 diabetes, PAD, and TcPo2 between 30 and 49 mm Hg were included. Patients were randomized to receive 1.8 mg of subcutaneous liraglutide or conventional treatment of cardiovascular risk factors (control group) for 6 months. Coprimary outcomes were the change from baseline of peripheral perfusion between groups and the comparison of the proportion of individuals who reached 10% increase of TcPo2 from baseline in each group. Fifty-five participants (mean [SD] age, 67.5 [8.5] years; 43 [78%] male) were randomized (27 to the liraglutide group and 28 to the control group) and analyzed. Participants had a median (IQR) hemoglobin A1c level of 6.9% (6.5%-7.8%) and a mean (SD) TcPo2 of 40.3 (5.7) mm Hg. Transcutaneous Po2 increased over time in both groups, with significant differences favoring the liraglutide group after 6 months (estimated treatment difference, 11.2 mm Hg; 95% CI, 8.0-14.5 mm Hg; P < .001). The 10% increase of TcPo2 occurred in 24 participants (89%) in the liraglutide group and 13 (46%) in the control group (relative risk, 1.91; 95% CI, 1.26-2.90; P < .001). Compared with the control group, individuals in the liraglutide group had a significant reduction of C-reactive protein (-0.4 mg/dL; 95% CI, -0.7 to -0.07 mg/dL; P = .02), urinary albumin to creatinine ratio (-119.4 mg/g; 95% CI, -195.0 to -43.8 mg/g; P = .003), and improvement of 6-minute walking distance (25.1 m; 95% CI, 21.8-28.3 m; P < .001). In this randomized clinical trial of people with type 2 diabetes and PAD, liraglutide increased peripheral perfusion detected by TcPo2 measurement during 6 months of treatment. These results support the use of liraglutide to prevent the clinical progression of PAD in individuals with type 2 diabetes. ClinicalTrials.gov Identifier: NCT04881110.

The effects of L-carnitine supplementation on inflammation, oxidative stress, and clinical outcomes in critically Ill patients with sepsis: a randomized, double-blind, controlled trial

BackgroundSepsis, a life-threatening organ dysfunction caused by a host’s dysregulated response to infection with an inflammatory process, becomes a real challenge for the healthcare systems. L-carnitine (LC) has antioxidant and anti-inflammatory properties as in previous studies. Thus, we aimed to determine the effects of LC on inflammation, oxidative stress, and clinical parameters in critically ill septic patients.MethodsA randomized double-blinded controlled trial was conducted. A total of 60 patients were randomized to receive LC (3 g/day, n = 30) or placebo (n = 30) for 7 days. Inflammatory and oxidative stress parameters (C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), superoxide dismutase (SOD), malondialdehyde (MDA), total antioxidant capacity (TAC), 28-day mortality rate, and some monitoring variables were evaluated.ResultsThere was no statistically significant difference between study arms in baseline characteristics and disease severity scores. CRP (p < 0.001) and ESR (p: 0.004) significantly reduced, and SOD (p < 0.001) and TAC (p < 0.001) significantly improved in the LC group after 7 days. Between-group analysis revealed a significant reduction in CRP (p: 0.001) and serum chloride (p: 0.032), an increase in serum albumin (p: 0.036) and platelet (p: 0.004) significantly, and an increase in SOD marginally (p: 0.073). The 28-day mortality rate was also lower in the LC group compared with placebo (7 persons vs. 15 persons) significantly (odds ratio: 0.233, p: 0.010).ConclusionsL-carnitine ameliorated inflammation, enhanced antioxidant defense, reduced mortality, and improved some clinical outcomes in critically ill patients with sepsis.Trial registrationIRCT20201129049534N1; May 2021.

Effects of carnosine and histidine-containing dipeptides on biomarkers of inflammation and oxidative stress: a systematic review and meta-analysis.

Carnosine and histidine-containing dipeptides (HCDs) are suggested to have anti-inflammatory and antioxidative benefits, but their effects on circulating adipokines and inflammatory and oxidative stress biomarkers remain unclear. The aim of the present systematic review and meta-analysis was to determine the impact of HCD supplementation on inflammatory and oxidative stress biomarkers. A systematic search was performed on Medline via Ovid, Scopus, Embase, ISI Web of Science, and the Cochrane Library databases from inception to 25 January 2023. Using relevant key words, trials investigating the effects of carnosine/HCD supplementation on markers of inflammation and oxidative stress, including C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), adiponectin, malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), total antioxidant capacity (TAC), and catalase (CAT) were identified. Meta-analyses were conducted using random-effects models to calculate the weighted mean differences (WMDs) and 95% confidence intervals (CIs). A total of 9 trials comprising 350 participants were included in the present meta-analysis. Carnosine/HCD supplementation led to a significant reduction in CRP (WMD: -0.97 mg/L; 95% CI: -1.59, -0.36), TNF-α (WMD: -3.60 pg/mL; 95% CI: -7.03, -0.18), and MDA (WMD: -0.34 μmol/L; 95% CI: -0.56, -0.12) and an elevation in CAT (WMD: 4.48 U/mL; 95% CI: 2.43, 6.53) compared with placebo. In contrast, carnosine/HCD supplementation had no effect on IL-6, adiponectin, GSH, SOD, and TAC levels. Carnosine/HCD supplementation may reduce inflammatory and oxidative stress biomarkers, and potentially modulate the cardiometabolic risks associated with chronic low-grade inflammation and lipid peroxidation.

Differential response to interleukin-1 blockade with anakinra on cardiorespiratory fitness in patients with heart failure with preserved ejection fraction stratified according to ejection fraction

Abstract Background Patients with heart failure with preserved ejection fraction (HFpEF) are a heterogeneous clinical population and might respond differently to pharmacologic therapies based on their baseline left ventricular EF (LVEF) (50-59% vs. ≥60%). Interleukin-1 (IL-1) is a key pro-inflammatory cytokine being explored as a therapeutic target in HFpEF for its effects on numerous outcomes including cardiorespiratory fitness (CRF). Purpose Our aim was to examine changes in CRF and C-reactive protein (CRP), a surrogate for IL-1 activity, in patients with HFpEF treated with the IL-1 recombinant human receptor antagonist anakinra, stratified according to resting LVEF. Methods We analyzed data from 32 patients (median age 55 [51-64] years, 24 (75%) female) with HFpEF, defined as a presence of HF symptoms, LVEF≥50%, and evidence of left ventricular diastolic dysfunction or elevated filling pressures. All patients were treated with anakinra 100 mg subcutaneously daily for 12 [2-12] weeks. Patients were stratified into two groups: LVEF 50-59% and LVEF ≥60%. At baseline and during treatment, patients underwent cardiopulmonary exercise testing and venipuncture to measure changes in peak oxygen consumption (peak VO2) and CRP. Categorical and continuous variables are expressed as N (%) and median (interquartile range) and were compared with the chi-square and Mann-Whitney test, respectively. The within-group paired differences were compared using the Wilcoxon signed-rank test. Results The cohort included 15 patients with LVEF 50-59% and 17 with LVEF ≥60%, without significant differences in age and sex between groups. In patients with LVEF 50-59% and ≥60%, baseline peak VO2 was 14.1 [13.1–17.3] and 13.8 [11.8-18.6] mLO2·kg-1·min-1, respectively (p = 0.82), and CRP was 6.2 [3.4-15.9] and 6.1 [3.7-17.6] mg/L, respectively (p = 0.74). A significant increase in peak VO2 (from 13.8 [11.8-18.6] to 15.8 [12.7-19.9] mLO2·kg-1·min-1, p = 0.033) and decrease in CRP (from 6.2 [3.4-15.9] mg/L to 3.4 [1.0-6.7] mg/L, p = 0.003) was seen in patients with LVEF ≥60%; whereas in those with LVEF 50-59% there were no significant changes in peak VO2 (from 14.1 [13.1–17.3] to 14.1 [11.0–17.3] mLO2·kg-1·min-1, p = 0.25) despite a significant reduction in CRP (from 6.1 [3.7-17.6] mg/L to 1.4 [0.8-11.4] mg/L, p = 0.016). We found a difference in the interval changes in peak VO2 (0 [from -1.1 to +0.3] vs +1.7 [from -0.7 to +2.3] mLO2·kg-1·min-1 in patients with LVEF 50-59% and ≥60%, respectively, p = 0.01), without differences in the interval change in CRP levels (–3.5 [from -6 to -2.1] vs –3.0 [from -11.4 to -2.1] mg/L, respectively, p = 0.91). Figure 1. Conclusions Patients with HFpEF demonstrate differential peak VO2 response to anakinra treatment based on resting LVEF, with those with a LVEF ≥60% showing greater improvement in CRF. Further randomized control trials are needed to validate these data and explore the potential underlying mechanisms.

The role of probiotic supplementation in inflammatory biomarkers in adults: an umbrella meta-analysis of randomized controlled trials.

Despite the increasing evidence for probiotics' anti-inflammatory effects, the results of meta-analyses remain inconsistent. The present umbrella meta-analysis aimed to investigate the effects of probiotic supplementation on inflammatory biomarkers. We performed a wide-ranging systematic search in several databases, including PubMed, Web of Science, Scopus, EMBASE, and Google Scholar up to April 2023. The overall effect sizes were calculated using effect size (ES) values and their corresponding confidence intervals (CI). Out of a total of 580 related articles, 39 studies were qualified for inclusion in the analysis. The results of the analysis revealed a significant reduction of C-reactive protein (CRP) (ES = -1.02; 95% CI: -1.23, -0.80, p < 0.001; I2: 94.1%, p < 0.001), TNF-α (ES = -0.35; 95% CI: -0.50, -0.20, p < 0.001; I2: 75.6%, p < 0.001), and interleukin-6 (IL-6) levels (ES = -0.36; 95% CI: -0.59, -0.13, p = 0.002; I2: 85.6%, p < 0.001), following probiotic supplementation. Probiotic supplementation significantly reduced serum concentrations of TNF-a, CRP, and IL-6. Thus, probiotic supplementation can be considered adjuvant therapy to alleviate inflammation in various inflammatory conditions.

Role of Janus Kinase inhibitors in the management of pulmonary involvement due to Long COVID-19 disease: A case control study.

Ongoing symptomatic coronavirus disease 2019 (OSC) is defined as persistent symptoms beyond 4 weeks of acute illness. OSC leads to prolonged hospitalization and oxygen dependence. We aimed to find the outcome of Janus kinase inhibitors (JAKi) as a steroid-sparing agent to treat OSC. In this single-center case-controlled study comparing JAKi and corticosteroids in OSC cases, data of 41 cases out of 86 were included - 21 in the JAKi group and 20 in the corticosteroid group from 4 weeks of acute illness to the next 4 weeks. Clinical parameters and inflammatory markers were recorded. The primary outcome was to compare the proportion of patients who were able to maintain oxygen saturation ≥95% with any oxygen supplementation in the two groups. The baseline clinical and demographic characteristics were similar in the two groups. The age was 53.65 ± 9.8 years and 51.48 ± 14.0 years in the corticosteroid group and JAKi group, respectively. At the baseline, 85% of patients in the corticosteroid group and 85.8% in the JAKi group were on oxygen support. The most common symptom in both groups was breathlessness followed by cough. Twenty percent of patients in the JAKi group received baricitinib and the remaining were given tofacitinib. At the time of follow-up, the majority of cases had a significant reduction in C-reactive protein (CRP) and D-dimer; however, the change in CRP and D-dimer was similar in both groups. The number of patients off oxygen support at 4 weeks was higher in the JAKi group (85% in the corticosteroid group vs. 95.2% in the JAKi group, P = 0.269), and the median time to liberation from oxygen support was significantly lower in JAKi group (19 days in corticosteroid group vs. 9 days in JAKi group, P < 0.001). The frequency of any adverse event was also higher in the corticosteroid group (70% vs. 23.8%, P = 0.003). JAKi can be used as immunomodulatory drugs in hypoxic OSC cases having evidence of ongoing inflammation.

Effects of Exercise on Inflammatory Markers in Individuals with Chronic Kidney Disease: A Systematic Review and Meta-Analysis.

Individuals with chronic kidney disease (CKD) have a systemic inflammatory state. We assessed the effects of exercise on inflammatory markers in individuals with CKD. An electronic search was conducted, including MEDLINE. Experimental clinical trials that investigated the effects of exercise on inflammatory markers in individuals with CKD at all stages were included. Meta-analyses were conducted using the random-effects model and standard mean difference (SMD). Subgroup analyses were performed for resistance, aerobic, and combined exercise interventions. Twenty-nine studies were included in the meta-analyses. Exercise interventions showed significant reductions in C-reactive protein (CRP) (SMD: -0.23; 95% CI: -0.39 to -0.06), interleukin (IL)-6 (SMD: -0.35; 95% CI: -0.57, -0.14), and tumor necrosis factor-alpha (TNF-α) (SMD: -0.63, 95% CI: -1.01, -0.25) when compared with the controls. IL-10 levels significantly increased (SMD: 0.66, 95% CI: 0.09, 1.23) with exercise interventions. Resistance interventions significantly decreased CRP (SMD: -0.39, 95% CI: -0.69, -0.09) and TNF-α (SMD: -0.72, 95% CI: -1.20, -0.23) levels, while increasing IL-10 levels (SMD: 0.57, 95% CI: 0.04, 1.09). Aerobic interventions only significantly reduced IL-6 levels (SMD: -0.26, 95% CI: -0.51, -0.01). No significant changes in any inflammatory markers were observed with combined exercise interventions. Exercise interventions are effective as an anti-inflammatory therapy in individuals with CKD compared to usual care control groups. Resistance interventions seem to promote greater anti-inflammatory effects.

Utility of the Brixia CXR score, C-Reactive Protein and Absolute Neutrophil Count in Predicting the Need for Invasive Mechanical Ventilation, Length of Hospital Stay, and Mortality in Moderate to Severe COVID-19 Patients

Background: The Brixia Chest X-ray (CXR) score, C-reactive protein (CRP), and the absolute neutrophil count (ANC) have been useful to predict outcomes in Coronavirus disease 2019 (COVID-19 patients). We studied the utility of the Brixia CXR score, CRP, and ANC in predicting the outcomes in terms of the need for invasive mechanical ventilation, length of stay, and mortality in moderatesevere COVID-19 patients. Materials and Methods: This was a single-centre, retrospective, study on 122 COVID -19 patients. Brixia CXR score, CRP, and ANC on admission to the hospital and the fifth day of hospital stay were noted along with the need for invasive mechanical ventilation (IMV), prolonged length of stay (LOS) ≥ 14 days, and mortality. Results: 122 patients were included for analysis. The median and interquartile range (IQR) for baseline CRP was 81.50 (39 -151) mg/L and 11.0 (4-30) mg/L (p &lt; 0.001) on the fifth day. The median and IQR for baseline Brixia score was 10.0 (7-13), and on the fifth day was 7 (4-11) (p &lt;0.001). The receiver operating characteristic curve (ROC) showed that the baseline CRP ≥ 52.5mg/L predicted both the need for IMV, with an area under the curve (AUC) of 0.628, and prolonged LOS with an AUC of 0.608. The ROC curve depicted that the baseline ANC &gt;8500/μL predicted IMV requirement with an AUC of 0.657. The fifth day CRP ≥ 32 mg/L, ANC ≥ 11,000/ μL and Brixia CXR score ≥ 7 predicted a higher mortality in hospitalized patients. Conclusion: Baseline CRP (&gt; 52.5mg/L) predicts the need for IMV and a prolonged LOS, but not mortality. Baseline ANC (&gt; 8500/μL) predicted the need for IMV. CRP, Brixia CXR score, and ANC on the fifth day were not useful to predict LOS or mortality, though there was a significant reduction in CRP and Brixia CXR score on the fifth day compared to baseline after treatment. The fifth day CRP ≥ 32 mg/L, ANC ≥ 11,000/ μL and Brixia CXR score ≥ 7 predicted a higher mortality.

An open-label, multicenter, phase 2 study of a food enriched with docosahexaenoic acid in adults with sickle cell disease

Sickle cell disease (SCD) induces red blood cell sickling, which causes debilitating symptoms including vaso-occlusion and inflammation. We investigated a food enriched with omega-3 fatty acids to determine its effect on certain factors: blood cell membrane fatty acid composition (including anti-inflammatory elements—docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA)—and the pro-inflammatory, arachidonic acid (AA)); the inflammation biomarker, C-reactive protein (CRP); and vaso-occlusive crisis (VOC) pain. Ten adults with SCD ingested the food, daily, for 28 days. Evaluated measures included blood cell membrane fatty acid ratios (AA vs omega-3 (DHA+EPA)), CRP (mg/L) levels, and Visual Analogue Scale (VAS) scores (a VOC assessment). The food was well tolerated and led to a statistically significant CRP reduction (39%). However, changes in omega-3 fatty acid ratios and VAS scores were not significant. Overall, while the omega-3-enriched food reduced inflammation, larger, blinded studies are needed to assess its effectiveness on other measures.

The impact of Emblica Officinalis (Amla) on lipid profile, glucose, and C-reactive protein: A systematic review and meta-analysis of randomized controlled trials

Background and aimsEmblica Officinalis (Amla) is a plant often utilized in traditional medicine due to its purported anti-inflammatory, antioxidant, hypoglycemic, and hypolipidemic properties. However, current evidence regarding its potential for preventing and treating metabolic abnormalities associated with chronic diseases remains unclear. MethodsThis systematic review and meta-analysis aimed to examine the effects of Amla supplementation on lipid profile, glucose, and C-reactive protein (CRP) concentrations in adults. We completed a systematic search (current as of December 2022) of all available randomized controlled trials (RCTs) in the database including ISI Web of Science, PubMed, Scopus, and Embase. Any effect's mean difference (MD) was calculated using a random-effects model. Weighted mean difference (WMD) and 95% confidence intervals (CIs) were calculated also calculated using a random-effects model. ResultsFive RTCs were included in the meta-analysis. Following Amla supplementation, pooled results showed a significant reduction in CRP (p = 0.002), fasting blood glucose (FBG) (p < 0.001), low-density lipoprotein cholesterol (LDL-c) (p < 0.001), total cholesterol (TC) (p < 0.001), and serum triglyceride (TG) (p < 0.001) concentrations as well as an increase in high-density lipoprotein cholesterol (HDL-c) (p < 0.001). The baseline concentration of biochemical indicators was used for subgroup analysis. ConclusionAmla supplementation shows promise for improving metabolic parameters in adults. In general, the populations included in the analysis were generally 40–58 years with an average BMI of 25.5 and a length of intervention ranging from 3 to 12 weeks. Thus additional investigations are warranted to confirm and expand the findings presented herein.

The Effect of Dietary Patterns on Inflammatory Biomarkers in Adults with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Some evidence supports the fact that chronic low-grade inflammation contributes to the physiopathology of type 2 diabetes mellitus (T2DM), and circulating markers of inflammation (e.g., C-reactive protein (CRP), pro- and anti-inflammatory biomarkers (e.g., adiponectin), and endothelial function markers could indicate an ongoing pathology. Following certain dietary patterns (DPs) may result in favorable changes in inflammatory biomarkers. The overarching aim of this systematic review and meta-analysis is to explore the inflammatory effect of healthy DPs on inflammatory biomarkers in adults with T2DM. A systematic search of the literature was conducted using the electronic databases MEDLINE, SCOPUS, and Cochrane Central Register of Controlled Trials. A total of 10 randomized controlled clinical trials (RCTs) were analyzed. In our linear meta-analysis, the random-effects model was applied to estimate standardized mean differences (SMD) to associate the effect of the interventions. Dietary Approaches to Stop Hypertension (DASH), Diabetes UK healthy eating, Mediterranean Diet (MD), Diabetes Prevention Program (DPP), and the American Heart Association’s Therapeutic Lifestyle Changes diet were associated with a significant reduction in CRP (SMD: −0.83, 99% CI −1.49, −0.17, p < 0.001; I2 94%), while plasma levels of adiponectin were significantly higher with the intake of MD, DPP, and Diabetes UK healthy eating (SMD: 0.81, 99% CI 0.06,1.56, p < 0.005; I2 96%), both of which indicate less inflammation. Sensitivity analyses were carried out, and potential publication bias was examined. In conclusion, low- moderate-quality evidence from RCTs suggests that, for the DPs evaluated, there are favorable changes in CRP and adiponectin.

Transcutaneous Auricular Vagus Nerve Stimulation Improves Inflammation but Does Not Interfere with Cardiac Modulation and Clinical Symptoms of Individuals with COVID-19: A Randomized Clinical Trial.

Transcranial auricular vagus nerve stimulation (taVNS) has shown effectiveness in reducing inflammation and depression. Thus, this study evaluated its effect on inflammation, cardiac autonomic modulation, and clinical symptoms in individuals affected by COVID-19. Methods: There were 52 randomized participants hospitalized with COVID-19 diagnosis who were to receive active (a-taVNS) or sham taVNS (s-taVNS) for 90 min twice a day for seven consecutive days. Interleukin 6 (IL-6), 10 (IL-10), cortisol, C-reactive protein (CRP), heart rate variability (HRV), and clinical symptoms were assessed before and after seven days of treatment. There were also seven- and fourteen-day follow-ups for clinical symptoms, including anxiety and depression levels, as well as a six-month follow-up for memory and attention levels. Results: There was significant reduction in CRP −23.9%, (95% CI −46.3 to −1.4) and IL-6 −37.7%, (95% CI −57.6 to −17.7) for the a-taVNS group. There were no changes in IL-10, cortisol levels, or in HRV results (p > 0.05) in both groups. There were no changes regarding clinical symptoms, except for a significant decrease in depression level (−2.85, 95% CI −5.44 to −0.27) in the a-taVNS group. Conclusion: taVNS showed effects on CRP, IL-6, and depression levels; however, it did not affect other clinical symptoms.

Probiotic supplementation induces remission and changes in the immunoglobulins and inflammatory response in active ulcerative colitis patients: A pilot, randomized, double-blind, placebo-controlled study.

Clinical studies of using probiotics for managing ulcerative colitis (UC) in Jordan are rare. Therefore, we aimed to evaluate the effect of probiotic supplementation on the clinical disease activity and biochemical parameters in patients with mild-to-moderately active UC. thirty mild-to-moderate ulcerative colitis patients were included and randomly assigned to participate in a double-blinded randomized study to receive the treatment (3×1010 of probiotic capsules [containing nine Lactobacillus and five Bifidobacterium species], or a placebo), and included in the intention-to-treat analysis. Only 24 completed the study and were included in the per-protocol analysis. Both groups were compared in terms of clinical disease activity and biochemical parameters at the beginning and the end of the study. Registered under ClinicalTrials.gov Identifier no. NCT04223479. There was a significant induction of remission in the probiotic group presented by improvement in the partial mayo score (PMS). Probiotic group had significantly lower stool frequency (0.00±0.00 vs. 1.17±1.19), global assessment (0.42±0.51 vs. 1.00±0.74, p=0.035), and total PMS score (1.33±0.49 vs. 3.42±1.78). In terms of mean and percent of change in post-to pre-treatment values, there was a significant reduction in C-reactive protein, and an increase in hemoglobin, hematocrit, and RBC levels in the probiotic group (p<0.05). Additionally, there was a significant reduction in the IgA level and an increase in IL-10 levels among the probiotic group compared to the placebo group (p=0.039). The use of probiotic therapy had significantly induced remission in UC patients, this was evidenced by the improvement in the Partial Mayo score. Furthermore, probiotic therapy had an appropriate effect on changes in hemoglobin, hematocrit, C-reactive protein, IgA, and IL-10 levels. This study was registered at ClinicalTrials.gov with the number NCT04223479.

Changes in circulating sirtuin 1 after bariatric surgery

Background and aimsObesity is associated with chronic inflammation and oxidative stress. Weight loss after bariatric surgery improves the inflammatory state and risk of cardiovascular disease. Improvement in metabolic dysfunction might be associated with changes in the activity of sirtuin 1 (SIRT1) and we aimed to investigate the effect of bariatric surgery on its circulating levels. Methods and resultsThis is a sub-study of a prospective cohort study, including 110 subjects with morbid obesity. The surgical procedure was either laparoscopic Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Blood was sampled at inclusion and six and 12 months after surgery. SIRT1 was measured in EDTA plasma with an enzyme-linked immunosorbent assay. The mean age in the population was 43 years, 80% were women and mean body mass index (BMI) was 38.8 kg/m2. RYGB and SG were performed in 89 and 21 subjects, respectively. SIRT1 concentration was significantly reduced from baseline to six and 12 months after surgery, with mean values (SD) 156.8 (82.6), 119.5 (65.6) and 94.9 (45.6) ng/mL, respectively, (p ≤ 0.002, all), accompanied by significant reductions in C-reactive protein (CRP), BMI and triglycerides from inclusion (p < 0.001, all). Type of surgery did not differently modify SIRT1 levels (p = 0.09). CRP and triglycerides were both positively predictive of SIRT1 levels (p ≤ 0.001, both). ConclusionSIRT1 concentration was significantly lower six and 12 months after bariatric surgery. CRP and triglycerides independently predicted SIRT1 levels, suggesting that reduction in SIRT1 levels might not intrinsically be related to weight reduction, but to improvement in metaflammation.

Aerobic Exercise Associated with Fish Oil Supplementation Decreases C-Reactive Protein and Interleukin-6 in Celiac Disease Patients.

Background Several studies indicate that celiac disease patients present alterations within anthropometric, metabolic, and inflammatory parameters, while physical exercise and fish oil are known to activate modulatory pathways of such parameters. Objective To investigate the effects of a 12-week-long protocol of aerobic exercise and its association with fish oil supplementation in nineteen adult celiac disease patients. Material and Methods. The celiacs were divided into 2 groups: (A) FOS: supplementation (n = 11); and (B) EXE: supplementation and exercise (n = 8). The celiac groups were compared to the adult healthy control group (CTR) (n 12). Aerobic exercises were performed weekly, in three sessions of 60 minutes each, with a maximal heart rate intensity of 60–70%. The participants received 2 g/day of fish oil, a daily intake of 420 mg of eicosapentaenoic acid, and 230 mg of docosahexaenoic acid. The following measurements were taken in four phases: (A) anthropometry: body mass, height, body mass index, waist-to-hip ratio, fat mass, and fat-free mass; (B) metabolic profile: total cholesterol, triglycerides, HDL, and LDL; and (C) inflammatory profile: C-reactive protein and interleukin-6. Results Supplementation associated with aerobic exercise promoted a significant reduction in C-reactive protein (P < 0.01) and increased the proportion of individuals in the undetectable range of interleukin-6. Conclusions The associated interventions showed a corrective and preventive potential in relation to disorders associated with chronic inflammation; however, the experimental design does not allow us to discriminate between the biological effects that are dependent on the association between interventions and those exclusively dependent on aerobic exercise.
