Objective: The objective of the study was to evaluate the impact of lesions of endodontic origin (LEO) and their treatment on the patients’ serum high-sensitivity C-reactive protein (hs-CRP) levels. Materials and Methods: A total of 20 healthy patients with radiographic evidence of LEO in at least one tooth were recruited for the study, of which 11 were finally evaluated. Before initiating the endodontic treatment, 10 ml of patient’s venous was taken from the antecubital vein to assess the pre-operative serum hs-CRP levels (T0). Canals were prepared with K-files till a suitable size and irrigated with 2.5% sodium hypochlorite. At the subsequent appointment after 1 week, teeth were obturated. The patients were then recalled 30 days after the completion of endodontic therapy. Again blood samples will be taken at time-frame T1 to assess the serum hs- CRP levels. The change in pre- and post-treatment values for T0 and T1 was statistically evaluated to assess the effect of treatment on serum hs-CRP levels. Results: The mean CRP (mg/L) at T0 ± SD (Range) at baseline was 6.18 ± 3.72 (0.96–11.02) and the mean CRP at T1 ± SD (Range) was 3.92 ± 3.59 (1.108–11.04) and mean change in CRP ± SD (Range) after 30 days follow-up was −2.26 ± 3.04 (−8.26–1.16). Significance of change in CRP levels (Paired t-test) was t = 2.458; P = 0.034. Conclusion: The results of the present study indicate that root canal treatment reduced the levels of hs-CRP in the serum of the patients having LEO. Timely diagnosis and treatment of these lesions may have some contribution in reducing systemic inflammatory burden.

Abstract Background Competing risk method has not been used in a large-scale prospective study to investigate whether increased levels of high-sensitivity C-reactive protein (hs-CRP) elevate the risk of primary liver cancer (PLC). Our study aims to prospectively investigate the relationship between hs-CRP and new-onset PLC. Methods and results Ninety-five thousand seven hundred fifty-nine participants without the diagnosis of PLC, and who had their demographic characteristics and biochemical parameters recorded, were analyzed from the Kailuan Cohort study. Cox proportional hazards regression models and competing risk regression models were used to evaluate the hazard ratios (HRs) and 95% confidence intervals (95% CIs) of PLC. During a median follow-up of 11.07 years, 357 incidental PLC cases were identified over a total of 1,035,039 person-years. The multivariable HRs (95%CI) for the association of hs-CRP of 1–3 mg/L group and hs-CRP>3 mg/L with PLC were 1.07(0.82 ~ 1.38), 1.51(1.15 ~ 1.98) in a Cox proportional hazard regression analysis adjusted for other potential confounders. In the cause-specific hazard model, the multivariable HRs (95%CI) for the association of hs-CRP of 1–3 mg/L group and hs-CRP>3 mg/L with PLC were 1.06(0.81 ~ 1.40), 1.50(1.14 ~ 1.99). Similar results were also observed in the sub-distribution hazard function model with corresponding multivariate HRs (95%CI) of 1.05(0.80 ~ 1.40), 1.49(1.13 ~ 1.98) in hs-CRP of 1–3 mg/L group and hs-CRP>3 mg/L group, respectively. Conclusions This prospective study found a significant association of higher levels of hs-CRP with new-onset PLC. The main clinical implications would be an increased awareness of hs-CRP and its correlation to the risk of PLC. This study should be a steppingstone to further research on chronic inflammation and PLC. Trial registration Registration number:ChiCTR–TNRC–11001489.

Abstract Background: Altered high-density lipoprotein cholesterol (HDL-C) composition in patients with chronic kidney disease is common. However, reports on the distribution of HDL-C subclasses in patients undergoing hemodialysis (HD) are limited. Objective: We aimed to compare the two main HDL-C subclasses, HDL-2b and HDL-3, in two cohorts of HD patients and healthy individuals and examine their associations with clinical characteristics. Methods: A total of 164 prevalent HD patients and 71 healthy individuals in one hospital-facilitated outpatient clinic were enrolled from May 2019 to July 2019. The HDL-2b and HDL-3 proportions were measured and statistical analysis was performed. Results: The mean ages of HD patients and healthy individuals were 63 and 49.9 years, respectively. HD patients showed lower HDL-2b and HDL-3 proportions compared with those of healthy individuals (23.6% vs. 31.2%, P < 0.001; 31.7% vs. 33.6%, P = 0.137, respectively). The HDL-2b proportion was significantly higher with a high-sensitivity C-reactive protein (hs-CRP) levels of <3 mg/L compared with hs-CRP ≥3mg/L in the HD cohort (P = 0.005). HDL-3 proportion was lower with a hs-CRP level of <3 mg/L compared with hs-CRP ≥3mg/L in the HD cohort (P = 0.022). Sex and diabetes did not influence the HDL-2b and HDL-3 proportions in the HD cohort.Conclusions: HD patients had lower HDL-2b and HDL-3 proportions than those of healthy individuals. The distribution of the HDL-2b and HDL-3 subclasses in HD patients is influenced by proinflammatory status, not by sex and diabetic status.

Abstract Objective: We performed the cohort study to evaluate the association between BMI, high-sensitivity C-reactive protein (hs-CRP) and the conversion from metabolically healthy to unhealthy phenotype in Chinese adults. Design: Metabolically healthy was defined as participants without history of metabolic diseases and with normal fasting blood glucose level, glycated Hb A1c level, blood pressure, lipid profile, serum uric acid level and liver ultrasonographic findings at baseline. Participants were either classified into normal weight (18·5 ≤ BMI < 24·0 kg/m2) and overweight (BMI ≥ 24·0 kg/m2) based on baseline BMI, or low (<1 mg/l) and high (≥1 mg/l) groups based on baseline hs-CRP. The conversion from metabolically healthy to unhealthy phenotype was deemed if any of the metabolic abnormalities had been confirmed twice or more during 5 years of follow-up. Results: Included were 4855 (1942 men and 2913 women, aged 36·0 ± 8·9 years) metabolically healthy Chinese adults. We identified 1692 participants who converted to metabolically unhealthy phenotype during the follow-up. Compared with their counterparts, the adjusted hazards ratio of the conversion was 1·19 (95 % CI 1·07, 1·33) for participants with overweight, while it was 1·15 (95 % CI 1·03, 1·29) for those with high hs-CRP level (≥1 mg/l). Further adjustment of hs-CRP did not materially change the association between BMI and the conversion. However, the association between hs-CRP and the conversion was not significant after further adjustment of BMI. The sensitivity analysis generated similar results to main analysis. Conclusion: BMI was associated with the risk of the conversion from metabolically healthy to unhealthy status in Chinese adults.

ObjectivesGallstone disease (GSD) can be caused by various health and clinical factors such as obesity, dyslipidaemia and an unhealthy diet, all of which are associated with higher high-sensitivity C reactive protein (hs-CRP) concentrations. Whether hs-CRP represents an independent risk factor for GSD is still unclear. We prospectively investigated hs-CRP in relation to the occurrence of GSD based on the Kailuan study.Study designProspective cohort study.SettingThe Kailuan cohort study was conducted in Tangshan City in northern China.Participants95 319 participants who were free from GSD were recruited in this study. Epidemiological data, anthropometric parameters and biochemical data of participants were collected.Primary and secondary outcome measuresCox proportional hazards regression models were used to evaluate the association between hs-CRP concentrations and the risk of GSD after adjustments for potential confounders.ResultsDuring the mean 7.58 years of follow-up among 95 319 participants, 4205 participants were identified as newly diagnosed with GSD or having undergone cholecystectomy for cholelithiasis. Compared with the hs-CRP<1 mg/L group, elevated hs-CRP concentrations were significantly associated with higher risk of GSD with the corresponding HR of 1.11 (95% CI 1.03 to 1.19), 1.12 (95% CI 1.04 to 1.22) in the 1≤hs-CRP≤3 mg/L and hs-CRP>3 mg/L group, respectively. The multivariate model which included hs-CRP not only had a better line of fitness but also had better predictive values to help identify new cases of GSD during follow-up.ConclusionElevated hs-CRP concentration is an independent risk factor for new-onset GSD among the Chinese population.Trial registration numberChiCTR-TNC-11001489.

Background: Both C-reactive protein (CRP) and arterial stiffness are associated with the development of cardiovascular disease (CVD). This study was performed to investigate whether a combination of these two measurements could improve cardiovascular risk stratification. Methods: A total of 6572 consecutive subjects (mean age, 60.8 ± 11.8 years; female, 44.2%) who underwent both high-sensitivity CRP (hs-CRP) and brachial–ankle pulse wave velocity (baPWV) measurement within 1 week were retrospectively analyzed. Major adverse cardiovascular events (MACE), including cardiovascular death, acute myocardial infarction, coronary revascularization, and stroke were assessed during the clinical follow-up. Results: During a mean follow-up period of 3.75 years (interquartile range, 1.78–5.31 years), there were 182 cases of MACE (2.8%). The elevated baPWV (≥1505 cm/s) (hazard ratio (HR), 4.21; 95% confidence interval (CI), 2.73–6.48; p < 0.001) and hs-CRP (≥3 mg/L) (HR, 1.57; 95% CI, 1.12–2.21; p < 0.001) levels were associated with MACE even after controlling for potential confounders. The combination of baPWV and hs-CRP further stratified the subjects’ risk (subjects with low baPWV and hs-CRP vs. subjects with high baPWV and hs-CRP; HR, 7.08; 95% CI, 3.76−13.30; p < 0.001). Adding baPWV information to clinical factors and hs-CRP had an incremental prognostic value (global Chi-square score, from 126 to 167, p < 0.001). Conclusions: The combination of hs-CRP and baPWV provided a better prediction of future CVD than either one by itself. Taking these two simple measurements simultaneously is clinically useful in cardiovascular risk stratification.

Background: We previously demonstrated that inflammatory biomarkers such as myeloperoxidase (MPO), a member of the heme peroxidase superfamily, and neopterin (produced by activated macrophages after interferon-γ stimulation by T-lymphocytes) are important in the pathogenesis of coronary plaque instability. Additional evidence supports high sensitivity C-reactive protein (hs-CRP) as an independent predictor of increased coronary risk. We assessed the prognostic significance of plasma MPO and neopterin levels, and serum hs-CRP levels in patients with stable angina pectoris (SAP) and unstable angina pectoris (UAP). Methods: Plasma MPO, neopterin, and serum hs-CRP levels were measured in 219 SAP patients and 144 UAP patients at admission. Cardiovascular (CV) events were defined as sudden cardiac death, fatal or non-fatal myocardial infarction and other non-fatal events including unstable angina pectoris or coronary revascularization. Results: Over a mean follow-up of 27±14 months, 56 SAP patients (26%) had CV events. When SAP patients were stratified based on the median neopterin level (15.0 nmol/L), Kaplan-Meier analysis showed that the high-neopterin group (>15.0 nmol/L) had significantly worse outcomes (P=0.015) than the low-neopterin group. Multivariate analysis showed that elevated neopterin was the only independent factor associated with CV events (OR, 2.19; 95% CI, 1.18-4.09; P=0.014). In contrast, over a mean follow-up of 30±24 months, 33 UAP patients (23%) had CV events. When UAP patients were divided based on the median MPO level (16.0 ng/mL), Kaplan-Meier analysis showed that the high-MPO group (>16.0 ng/mL) had significantly worse outcomes (P=0.012) than the low-MPO group. Multivariate analysis showed that elevated MPO was the only independent factor associated with CV events (OR, 2.58; 95% CI, 1.07-6.23; P=0.035). With regard to hs-CRP levels, there were no significant differences in CV events between the two groups according to the median hs-CRP in both SAP and UAP patients. Conclusions: The clinical significance of elevated MPO and neopterin levels as independent predictors of CV events differs depending on the clinical condition of SAP and UAP patients, because of different production mechanisms of these biomarkers.

BackgroundThis study aimed to assess the association of high sensitivity C-reactive protein (hs-CRP) with cardiovascular disease (CVD) in middle-aged Chinese population.MethodsThe baseline was collected 2009–2010, and follow-up was conducted in 2016–2017. Data of hs-CRP were from baseline examination and re-examination in 2016–2017 using transmission turbidimetry with a measurement range of 0–42 000. The primary outcome was CVD including coronary heart disease events and stroke events.ResultsAmong 8688 participants free from CVD (at baseline, mean age, 50.1 years, 3897 were males), there were 189 CVD events, occurred during a median follow-up of 6.34 years (54 685 person-years at risk). From the Kaplan-Meier curve, we found that there was a progressive increase in CVD event rates by hs-CRP tertiles (log-rank test, p<0.001). Baseline hs-CRP was linearly associated with CVD (p for trend=0.015) even after adjusting for known CVD risk factors. Furthermore, the net reclassification improvement when hs-CRP was added to a model based on traditional factors was 7.85% for CVD (p=0.003). In addition, the correlation between change of hs-CRP and CVD was conducted in a subgroup (n=4778). However, we did not find the correlation between hs-CRP change and CVD (correlation coefficient: −0.003, p=0.846).ConclusionsIn the middle-aged Chinese population, hs-CRP was associated with increased risk of developing CVD. Although there was no correlation between hs-CRP change and CVD, the level of hs-CRP was higher at follow-up than baseline even among those with CVD. More attention should be given to those with higher level of hs-CRP for CVD prevention.

Background: Stroke has been found to be the fourth most fatal cause of death around the globe. Decreased activity and physical work are the major causes of increased incidences of stoke worldwide. It has also been studied that elevated levels of high-sensitivity C-reactive protein (hs-CRP) have been related to vascular inflammation whereas CRP is an important biomarker of systemic inflammation. Aim of this study to measure serum high-sensitivity C-reactive protein (hs-CRP) levels in the patients presenting with stroke, and evaluating its correlation as a prognostic marker in stroke patients.Methods: It was an observational prospective hospital-based case study carried out at Teerthanker Mahaveer Medical College and Research Centre, a tertiary care hospital situated in Moradabad, India for 5 months period from 1st November 2018 to 31st March 2019. 100 patients of new-onset stroke were included in the study.Results: According to the Scandinavian score, the majority of the patients who had ischemic stroke depicted a score range from 2-8. On the other hand, the majority the patients with hemorrhagic score had a Scandinavian score >14. The mean hs-CRP, when observed between different ranges of the Scandinavian score, showed that in 2-8 range the mean hs-CRP was 31.49±15.00, the mean hs-CRP for 9-14 range was 7.99±6.32 and the mean hs-CRP for >14 range was 7.10±0.32.Conclusions: It can be identified that levels of hs-CRP can be used as a marker to predict the long term prognosis of patients with stroke. In addition to this, it can also be identified that patients with higher levels of hs-CRP have lower Scandinavian score and the patients with lower hs-CRP levels have a higher Scandinavian score. Also, the results show that patients with ischaemic stroke have higher hs-CRP levels as compared to hemorrhagic stroke.

AbstractBackgroundHigh-sensitivity C-reactive protein (hs-CRP) has been suggested to be involved in the process of cognitive decline. However, the results from previous studies exploring the relationship between hs-CRP concentration and cognitive decline are inconsistent.MethodWe employed data from wave 2 (2004–2005) to wave 7 (2014–2015) of the English Longitudinal Study of Ageing. Cognitive function was assessed at baseline (wave 2) and reassessed biennially at waves 3–7.ResultsA total of 5257 participants (54.9% women, mean age 65.4 ± 9.4 years) with baseline hs-CRP levels ranged from 0.2 to 210.0 mg/L (median: 2.0 mg/L, interquartile range: 0.9–4.1 mg/L) were studied. The mean follow-up duration was 8.1 ± 2.8 years, and the mean number of cognitive assessment was 4.9 ± 1.5. Linear mixed models show that a one-unit increment in natural log-transformed hs-CRP was associated with faster declines in global cognitive scores [−0.048 points/year, 95% confidence interval (CI) −0.072 to −0.023], memory scores (−0.022 points/year, 95% CI −0.031 to −0.013), and executive function scores (−0.025 points/year, 95% CI −0.043 to −0.006), after multivariable adjustment. Compared with the lowest quartile of hs-CRP, the multivariable-adjusted rate of global cognitive decline associated with the second, third, and highest quartile was faster by −0.043 points/year (95% CI −0.116 to 0.029), −0.090 points/year (95% CI −0.166 to −0.015), −0.145 (95% CI −0.221 to −0.069), respectively (pfor trend <0.001). Similarly, memory and executive function also declined faster with increasing quartiles of hs-CRP.ConclusionsA significant association between hs-CRP concentration and long-term cognitive decline was observed in this study. Hs-CRP might serve as a biomarker for cognitive decline.

Abstract. Background: This prospective study was designed to evaluate the effect of inflammatory markers on the presence and progression of subclinical markers of carotid atherosclerosis in a 3.8-year follow-up period in patients with type 2 diabetes mellitus (T2DM). Patients and methods: A total of 595 subjects with T2DM were enrolled. Subclinical markers of carotid atherosclerosis (carotid intima media thickness (CIMT), plaque thickness, and plaques presence) were assessed with ultrasound at the time of recruitment and again after 3.8 years. Subjects with T2DM were divided into 2 groups according to the plasma high sensitive C-reactive protein (hs-CRP) levels (subjects with hs-CRP ≥ 2 mg/L and subjects with hs-CRP below 2 mg/L). Results: Subjects with T2DM and hs-CRP levels ≥ 2 mg/L had higher CIMT in comparison with subjects with T2DM and hs-CRP levels below 2 mg/L, and higher incidence of plaques/unstable plaques in comparison with subjects with T2DM and hs-CRP levels below 2 mg/L. Multivariate logistic regression analysis found the association between the HDL cholesterol level and presence of plaques, whereas the inflammatory marker hs-CRP was not associated with subclinical markers of progression of carotid atherosclerosis. Multiple linear regression analysis found the association between the hs-CRP levels and either CIMT progression rate or a change in the number of sites with plaques in a 3.8-year follow-up. Conclusions: We demonstrated an association between the inflammatory marker hs-CRP and either CIMT or incidence of plaques/unstable plaques at the time of recruitment in Caucasians with T2DM. Moreover, we found the association between hs-CRP levels and either CIMT progression rate or a change in the number of sites with plaques in a 3.8-year follow-up in subjects with T2DM.
