Background “Quantile-dependent expressivity” occurs when the effect size of a genetic variant depends upon whether the phenotype (e.g., C-reactive protein, CRP) is high or low relative to its distribution. We have previously shown that the heritabilities (h2) of coffee and alcohol consumption, postprandial lipemia, lipoproteins, leptin, adiponectin, adiposity, and pulmonary function are quantile-specific. Whether CRP heritability is quantile-specific is currently unknown. Methods Serum CRP concentrations from 2,036 sibships and 6,144 offspring-parent pairs were analyzed from the Framingham Heart Study. Quantile-specific heritability from full-sib (βFS, h2 ={(1 + 8rspouseβFS)0.5 − 1}/(2rspouse)) and offspring-parent regression slopes (βOP, h2 = 2βOP/(1 + rspouse)) were estimated robustly by quantile regression with nonparametric significance determined from 1,000 bootstrap samples. Results Quantile-specific h2 (±SE) increased with increasing percentiles of the offspring’s age- and sex-adjusted CRP distribution when estimated from βOP (Ptrend = 0.0004): 0.02 ± 0.01 at the 10th, 0.04 ± 0.01 at the 25th, 0.10 ± 0.02 at the 50th, 0.20 ± 0.05 at the 75th, and 0.33 ± 0.10 at the 90th percentile, and when estimated from βFS (Ptrend = 0.0008): 0.03±0.01 at the 10th, 0.06 ± 0.02 at the 25th, 0.14 ± 0.03 at the 50th, 0.24 ± 0.05 at the 75th, and 0.53 ± 0.21 at the 90th percentile. Conclusion Heritability of serum CRP concentration is quantile-specific, which may explain or contribute to the inflated CRP differences between CRP (rs1130864, rs1205, rs1800947, rs2794521, rs3091244), FGB (rs1800787), IL-6 (rs1800795, rs1800796), IL6R (rs8192284), TNF-α (rs1800629) and APOE genotypes following CABG surgery, stroke, TIA, curative esophagectomy, intensive periodontal therapy, or acute exercise; during acute coronary syndrome or Staphylococcus aureus bacteremia; or in patients with chronic rheumatoid arthritis, diabetes, peripheral arterial disease, ankylosing spondylitis, obesity or inflammatory bowel disease or who smoke.

Objectives Indoxyl sulfate, known for its cardiovascular toxicity, is associated with vascular and coronary artery diseases and increased mortality. Peripheral arterial disease, defined by low ankle–brachial index, is associated with increased mortality in patients on hemodialysis. The present study aimed to determine the relationship between the serum indoxyl sulfate level and peripheral arterial disease in patients on maintenance hemodialysis. Methods The present cross-sectional, single-center study included 75 patients on maintenance hemodialysis. Serum indoxyl sulfate levels were determined by high-performance liquid chromatography–mass spectrometry. Ankle–brachial index values were measured using an automated oscillometric device. Patients with ankle–brachial indexes of < 0.9 were categorized into the low ankle–brachial index group. Results In the study cohort, 12 of the 75 patients (16.0%) had low ankle–brachial indexes. The rates of diabetes mellitus ( p = 0.010) as well as the serum levels of C-reactive protein ( p < 0.001) and indoxyl sulfate ( p < 0.001) were higher in the low ankle–brachial index group than the normal ankle–brachial index group. The multivariable logistic regression analysis revealed that serum levels of indoxyl sulfate (odds ratio = 1.123, 95% confidence interval 1.011–1.249, p = 0.031) and C-reactive protein (each 0.1 mg/dL increase, odds ratio = 1.169, 95% confidence interval 1.018–1.343, p = 0.027) were independently associated with peripheral arterial disease in patients on maintenance hemodialysis. Conclusions Serum indoxyl sulfate levels were associated with peripheral arterial disease in patients on maintenance hemodialysis.

Objectives. We sought to assess the comparative value of inflammatory markers on the occurrence of left ventricular systolic dysfunction (LVSD) after an acute coronary syndrome (ACS).Methods. During 2006–2008, 760 patients with an ACS were enrolled. C-reactive protein (CRP) and white blood cell (WBC) count were measured during the first 12 hours of hospital admission.Results. CRP levels and WBC count were significantly higher in those who developed LVSD compared to those who did not. The analysis revealed that a 10 mg/dL increase of CRP levels and a 1000/L increase in WBC are associated with a 6% and a 7% increase in the likelihood of developing LVSD, respectively. Furthermore, WBC count at entry and CRP have almost the same predictive value for development of LVSD after an ACS ( versus ).Conclusions. Serum CRP levels and WBC count at entry are almost equally powerful independent predictors of LVSD, after an ACS.

Postprandial Triacylglycerol

The current study investigated the acute effects of accumulating short bouts of running on circulating concentrations of postprandial triacylglycerol (TAG) and C-reactive protein (CRP). Ten men, age 21–32 yr, completed two 1-d trials. On 1 occasion participants ran at 70% of maximum oxygen uptake in six 5-min bouts (i.e., 8:30, 10, and 11:30 a.m. and 1, 2:30, and 4 p.m.) with 85 min rest between runs. On another occasion participants rested throughout the day. In both trials, participants consumed test meals at 9 a.m. and 12 p.m. In each trial, venous blood samples were collected at 8:30, 10, and 11:30 a.m. and 1, 2:30, 4, and 5:30 p.m. for plasma TAG measurement and at 8:30 a.m. and 5:30 p.m. for serum CRP measurement. Total area under the curve for plasma TAG concentration versus time was 10% lower on the exercise trial than the control trial (M ± SEM: 13.5 ± 1.8 vs. 15.0 ± 1.9 mmol · 9 hr−1 · L−1; p = .004). Serum CRP concentrations did not differ between trials or over time. This study demonstrates that accumulating short bouts of running reduces postprandial plasma TAG concentrations (a marker for cardiovascular disease risk) but does not alter serum CRP concentrations.

Summary Background: Previous studies have indicated that high sensitivity C-reactive protein (hs-CRP) is a risk factor for the peripheral arterial disease (PAD) in diabetes. This study aimed to evaluate the possible predictive significance of hs-CRP for the development and progression of PAD in patients with type 2 diabetes (T2D). Methods: The study included 80 patients previously diagnosed with T2D, aged 45–70 years, divided into group A (T2D patients with PAD; n=38) and group B (T2D patients without PAD; n=42). After five years, all the patients were re-examined and divided into subgroups depending on de novo development of PAD or progression of previously diagnosed PAD. Ankle-Brachial Index (ABI) measurement was used for PAD diagnosis and hs-CRP was determined by nephelometry. Results: We found significantly higher hs-CRP levels in group A compared to group B, but only at baseline. Among the patients in group A, those with later progression of PAD (subgroup A1) had the highest levels of hs-CRP at baseline, although not significantly different from those in subgroup A2 (non-progressors). In contrast, hs-CRP level was significantly higher in subgroup B1 (progressors) in comparison to subgroup B2 (non-progressors) at both the first and second exam. Of all the investigated metabolic parameters, hs-CRP was the only independent predictor of PAD progression (OR=0.456, 95% CI=0.267–0.7815, p=0.004). The cut-off point for hs-CRP was 2.5 mg/L (specificity 75% and sensitivity 73.3%) with the relative risk for PAD of 2.93 (95% CI=1.351–6.3629). Conclusions: Our study implies that hs-CRP can be used as a reliable predictor for the progression of PAD in patients with T2D.

Background Peripheral arterial disease is associated with increased cardiovascular mortality and morbidity. C-reactive protein and albumin are biomarkers of inflammation and malnutrition that play key roles in the pathophysiological pathways involved in the progression of atherosclerosis and peripheral arterial disease. In this study, we aimed to assess the relationship between C-reactive protein to albumin ratio and the suprapopliteal peripheral arterial disease severity and complexity as assessed by TransAtlantic Inter-Society Consensus-II (TASC-II) classification. Method Our study enrolled 224 consecutive patients referred for peripheral angiography with the clinical features of possible peripheral arterial disease at a tertiary care center between January 2016 and September 2019. Level of disease and lesion characteristics were defined with reference to angiographic findings according to the TASC-II classification. Results C-reactive protein/albumin ratio levels were significantly higher in TASC-II class C and D than in TASC-II class B patients with a median level of 1.8 to 2.1 vs 1.4, respectively ( p = 0.018). In multivariate regression analysis, C-reactive protein to albumin ratio remained an independent predictor of severe peripheral arterial disease. The predictive performance of C-reactive protein to albumin ratio, C-reactive protein, and albumin were compared by Receiver Operating Characteristic curve analysis. C-reactive protein to albumin ratio surpassed C-reactive protein and albumin in predicting peripheral arterial disease severity and complexity. A level of C-reactive protein to albumin ratio  > 0.14 predicted a higher grade of suprapopliteal TASC-II class with sensitivity and specificity of 68.2% and 56.0%, respectively. Conclusion C-reactive protein to albumin ratio was strongly associated with peripheral arterial disease severity and complexity, as assessed by TASC-II classification. Also, C-reactive protein to albumin ratio was found to be a more accurate marker than C-reactive protein and albumin alone in predicting more severe and complex lesions in patients with peripheral arterial disease.

Objective: To review the role of elevated C - reactive protein (CRP) as a marker for predicting the development of Peripheral Arterial Disease (PAD). Methods: An online search was conducted using the most trusted medical data base PubMed and the articles published in peer-reviewed journals within the last 5 years (from the year 2005 to date) to collect evidence about the association of C-reactive protein with Peripheral Arterial Disease, using keywords like C-reactive protein, hs-C-reactive protein, inflammation, atherogenesis, peripheral arterial disease and their combinations. Out of 240 articles shown during online search on PubMed, only 17 articles related to the role of CRP and High sensitivity CRP (hs-CRP) as a marker in PAD. Results: 17 articles based on the role of CRP and High sensitivity CRP (hs-CRP) as a marker in PAD were studied and evaluated thoroughly working on their study design and outcomes. Almost all the 17 studies showed strong association hs-CRP with PAD. The results are described in the form of a table. Conclusion: CRP seems to be a marker of severity of PAD and it may serve as a strong prognostic indicator.
