Associations of plasma high-sensitivity C-reactive protein concentrations with all-cause and cause-specific mortality among middle-aged and elderly individuals. IMMUNITY & AGEING 2019; 16:28. [PMID: 31708993 PMCID: PMC6833146 DOI: 10.1186/s12979-019-0168-5] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 10/16/2019] [Indexed: 01/28/2023]
Abstract
Background The association of high-sensitivity C-reactive protein (hsCRP) with mortality is controversial. We aimed to investigate the associations of hsCRP concentrations with the risks of all-cause and cause-specific mortality and identify potential modifying factors affecting these associations among middle-aged and elderly individuals. Methods This community-based prospective cohort study included 14,220 participants aged 50+ years (mean age: 64.9 years) from the Health and Retirement Study. Cox proportional hazard models were employed to estimate the associations between the hsCRP concentrations and the risk of all-cause and cause-specific mortality with adjustment for sociodemographic and lifestyle factors, self-reported medical history, and other potential confounders. Results In total, 1730 all-cause deaths were recorded, including 725 cardiovascular- and 417 cancer-related deaths, after an 80,572 person-year follow-up (median: 6.4 years; range: 3.6–8.1 years). The comparisons of the groups with the highest (quartile 4) and lowest (quartile 1) hsCRP concentrations revealed that the adjusted hazard ratios and 95% confidence intervals were 1.50 (1.31–1.72) for all-cause mortality, 1.44 (1.13–1.82) for cardiovascular mortality, and 1.67 (1.23–2.26) for cancer mortality. The associations between high hsCRP concentrations and the risks of all-cause, cardiovascular, and cancer mortality were similar in the men and women (P for interaction > 0.05). Conclusions Among middle-aged and older individuals, elevated hsCRP concentration could increase the risk of all-cause, cardiovascular, and cancer mortality in men and women.

[PMID: 31699568 DOI: 10.1016/j.jjcc.2019.09.015] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 09/17/2019] [Accepted: 09/30/2019] [Indexed: 01/12/2023]
Abstract
BACKGROUND The effects of high-sensitivity C-reactive protein (hs-CRP) levels on clinical outcomes in chronic-phase acute coronary syndrome (ACS) patients undergoing aggressive lipid-lowering therapy remain unclear. We examined the effects of hs-CRP levels on the prognosis of ACS patients who underwent aggressive lipid-lowering therapy and determined treatment targets for hs-CRP value. METHODS This post-hoc sub-analysis of a prospective randomized control trial (HIJ-PROPER) included 1734 ACS patients with dyslipidemia, who were divided into hs-CRP quartiles after 3 months of treatment. Primary endpoints were combined all-cause death, non-fatal myocardial infarction, non-fatal stroke, unstable angina, and ischemia-driven coronary revascularization. Secondary endpoint was all-cause death. RESULTS The median follow-up period was 3.7 years. Overall, 1415 patients were evaluated retrospectively. No significant among-group differences were noted in low-density lipoprotein cholesterol (LDL-C) levels over time (p = 0.44). Kaplan-Meier analyses revealed that the incidence of the primary and secondary endpoints was significantly higher in the highest hs-CRP group than in the other groups [hazard ratio (HR) = 1.52, 95% confidence interval (CI) = 1.16-2.00, p < 0.01; HR = 5.30, 95% CI = 2.47-11.32, p < 0.01, respectively]. The cut-off hs-CRP level to predict all-cause death was 0.74 mg/L (receiver operating characteristic curve: sensitivity: 68%, specificity: 62%). Multivariate analyses revealed that hs-CRP ≥0.74 mg/L at 3 months was correlated with an increased risk of all-cause death (adjusted HR = 3.68, 95% CI = 2.22-6.10, p < 0.01). CONCLUSION Elevated hs-CRP levels independently predicted a worse prognosis, regardless of LDL-C levels, suggesting that interventions against elevated inflammatory responses plus intensive lipid-lowering therapy and coronary revascularization are encouraging options for secondary prevention in ACS patients.

Abstract
BACKGROUND To clarify the controversy regarding the relationship between serum high-sensitivity C-reactive protein (hs-CRP) levels and cognitive impairments in first-episode schizophrenic patients and examine whether hs-CRP is a potential objective biological indicator for evaluating cognitive impairment in first-episode schizophrenic patients. METHODS Serum hs-CRP levels were measured in 58 first-episode schizophrenic patients and 31 healthy controls using immunofluorescence. The Brief Psychiatric Rating Scale (BPRS) and the P300 event-related potential were assessed. The relationship between serum hs-CRP levels and both BPRS scores and P300 were analyzed. RESULTS Serum hs-CRP levels and BPRS scores were significantly higher in the study group than in the control group. The incubation period of P3 was longer, and the amplitude of P3 was larger in the study group than in the control group. Correlation analysis showed that in the study group, serum hs-CRP levels were positively correlated with BPRS total scores. Serum hs-CRP levels were also positively correlated with the incubation period of P3 and negatively correlated with P3 amplitudes. CONCLUSIONS Serum hs-CRP levels were positively associated with cognitive impairment in first-episode schizophrenic patients and potentially represent an objective biological indicator for the rapid evaluation of cognitive impairment in first-episode schizophrenic patients.

Abstract
OBJECTIVE To compare the dietary habits of children living in northern villages and in the capital of Greenland, given the reported transition from traditional to westernised diet in adults over recent decades, and to explore the association between consumption of marine mammals and fish (MMF) and the children's metabolic profile and vitamin D status. DESIGN Children answered an FFQ encompassing sixty-four individual food types pooled into six food categories. Their pubertal stage, body fat, fitness level, metabolic profile (non-HDL-cholesterol, glycated Hb, insulin, glucose, high-sensitivity C-reactive protein) as well as serum 25-hydroxyvitamin D (25(OH)D) concentration were evaluated. SETTING Siorapaluk and Qaanaaq (north of Greenland) and Nuuk (west). PARTICIPANTS Children aged 6-18 years (n 177). RESULTS MMF were most frequently eaten by children from Siorapaluk (mean (sd): 73·4 (14·1) times/month), followed by children from Qaanaaq (37·0 (25·0) times/month), and least often eaten by children from Nuuk (23·7 (24·6) times/month; P < 0·001). Children from Qaanaaq consumed 'junk food' more frequently (P < 0·001) and fruits and vegetables less frequently (P < 0·01) than children from Nuuk. MMF consumption was positively associated with serum 25(OH)D concentration (P < 0·05), but the overall prevalence of vitamin D deficiency was high (18 %). No association was found between MMF consumption and metabolic parameters. CONCLUSIONS The dietary transition and influence of western diets have spread to the north of Greenland and only the most remote place consumed a traditional diet highly based on MMF. We found no strong associations of MMF consumption with metabolic health, but a positive association with vitamin D status.

Abstract
BACKGROUND High-sensitivity C-reactive protein (hs-CRP) is a well-recognized biomarker of neurologic complications and clinical outcome of stroke patients. However, whether hs-CRP can predict the occurrence of acute kidney injury (AKI) in aneurysmal subarachnoid hemorrhage (aSAH) patients is still unclear. The objective of this study was to assess the feasibility of using serum hs-CRP level to predict the occurrence of AKI in aSAH patients. METHODS One hundred sixty-four aSAH patients were enrolled into a prospective observational study. AKI was diagnosed using the modified Kidney Disease Improving Global Outcomes (KDIGO) standard. The relationship between serum hs-CRP level at admission and occurrence of AKI was analyzed. RESULTS AKI occurred in 17 patients (10.4%) in this cohort. Patients with AKI had significantly higher hs-CRP levels than those without. The mortality of the AKI group tends to be higher than that of the non-AKI group, but the difference was not statistically significant (4/17 (23.5%) vs. 13/147 (8.8%), P = 0.081). After adjusting for possible confounding factors including World Federation of Neurosurgical Societies grade, diabetes, and serum creatinine, multivariate analysis revealed that serum hs-CRP level and antibiotic therapy were both significant factors independently associated with AKI following aSAH (serum hs-CRP: OR = 1.2, 95% confidence interval (CI) = 1.1-1.3, P = 0.003; antibiotic therapy: OR = 5.8, 95%CI = 1.6-20.7, P = 0.007). Receiver operating characteristic curve analysis showed that hs-CRP had a sensitivity of 76.5% and a specificity of 64.6% for predicting the development of AKI on the basis of the best thresholds. The post hoc log-rank test revealed that patients having serum hs-CRP level > 6.6 mg/L had a significantly higher AKI rate than patients having serum hs-CRP level ≤ 6.6 mg/L (P = 0.001). CONCLUSIONS Serum hs-CRP level might be helpful as a predictor for the development of AKI in aSAH patients. Delayed cerebral ischemia occurrence rate and mortality of patients with AKI tend to be higher than those of patients without in this cohort; however, they were not significantly different.

Abstract
Aims: Small dense low-density lipoprotein cholesterol (sdLDL-C) and remnant-like particle cholesterol (RLP-C) are the novel atherosclerotic risk factors and might be strongly associated with inflammation. The basic evidence supports that sdLDL and RLP have some different mechanisms inducing an inflammatory response. Many studies have focused on the mechanism of inflammation of sdLDL-C or RLP-C per se, with limited data on the association between sdLDL-C and RLP-C in the real-world, population-based setting. Thus, the aim of this study was to investigate the association between sdLDL-C and RLP-C with inflammation. Methods: We examined the baseline cross-sectional data of participants from the Jichi Medical School-II Cohort Study. In total, 5,305 participants (2,439 men and 2,866 women) were included in this study. Results: Of all quartiles of sdLDL-C, the fourth had the highest high-sensitivity C-reactive protein (hs-CRP) level. Once adjusted for age, sex, smoking status, homeostasis model assessment of insulin resistance, antidyslipidemic and antihyperglycemic medication use, and RLP-C, sdLDL-C was significantly and positively associated with hs-CRP (geometric mean, 95% confidence interval (CI), 0.36 mg/L (0.34–0.38 mg/L), 0.37 mg/L (0.35–0.39 mg/L), 0.40 mg/L (0.37–0.42 mg/L) versus 0.44 mg/L (0.42–0.47 mg/L), P < 0.001 for trend). After stratifying the participants into four sdLDL-C×four RLP-C categories, the group in the fourth sdLDL-C quartile and the forth RLP-C quartile had the highest hs-CRP level (geometric mean, 95% CI, 0.52 mg/L, 0.48–0.57 mg/L, interaction P = 0.75). Conclusions: SdLDL-C and RLP-C had different associations with inflammation. Our results support sdLDL-C as the potential novel factor of cardiovascular disease, independently of RLP-C.

Healthy diet reduces markers of cardiac injury and inflammation regardless of macronutrients: Results from the OmniHeart trial. Int J Cardiol 2019; 299:282-288. [PMID: 31447226 DOI: 10.1016/j.ijcard.2019.07.102] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2019] [Revised: 06/11/2019] [Accepted: 07/31/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Despite diet being a first-line strategy for preventing cardiovascular disease, the optimal macronutrient profile remains unclear. We studied the effects of macronutrient profile on subclinical cardiovascular injury and inflammation. METHODS OmniHeart was a randomized 3-period, crossover feeding study in 164 adults with high blood pressure or hypertension (SBP 120-159 or DBP 80-99 mm Hg). Participants were fed each of 3 diets (emphasizing carbohydrate (CARB), protein (PROT), or unsaturated fat (UNSAT)) for 6-weeks, with feeding periods separated by a washout period. Weight was held constant. Fasting serum was collected at baseline while participants ate their own diets and after each feeding period. High-sensitivity cardiac troponin I (hs-cTnI) and high-sensitivity C-reactive protein (hs-CRP) were measured in stored specimens. RESULTS The average age was 53.6 years, 55% were African American, and 45% were women. At baseline, the median (25th-percentile, 75th-percentile) hs-cTnI was 3.3 ng/L (1.9, 5.6) and hs-CRP was 2.2 mg/L (1.1, 5.2). Compared to baseline, all 3 diets reduced hs-cTnI: CARB -8.6% (95%CI: -16.1, -0.4), PROT -10.8% (-18.4, -2.5), and UNSAT -9.4% (-17.4, -0.5). Hs-CRP was similarly changed by -13.9 to -17.0%. Hs-cTnI and hs-CRP reductions were of similar magnitudes as SBP and low-density lipoprotein cholesterol (LDLc) but were not associated with these risk-factor reductions (P-values = 0.09). There were no between-diet differences in hs-cTnI and hs-CRP reductions. CONCLUSIONS Healthy diet, regardless of macronutrient emphasis, directly mitigated subclinical cardiac injury and inflammation in a population at risk for cardiovascular disease. These findings support dietary recommendations emphasizing healthy foods rather than any one macronutrient.

Abstract
BACKGROUND Several studies have indicated that inflammatory markers were associated with the risk of mild cognitive impairment (MCI) in type 2 diabetes (T2D). Serum folate was related to MCI as well as inflammation. However, no studies have investigated the association between inflammatory markers and MCI taking account of serum folate level in T2D patients. This study aimed to conduct a case-control study to evaluate the association between inflammatory markers and MCI taking account of serum folate level in Chinese patients with T2D. METHODS This study consisted of 126 T2D patients (63 cases with MCI and 63 controls without MCI). Clinical parameters, serum folate, high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) were measured. Spearman correlation analysis and logistic regression analysis were used to analyze the association between the inflammatory markers and the risk of MCI in T2D patients. RESULTS There were higher serum hs-CRP, IL-6 and TNF-α in T2D cases with MCI compared with the controls. Serum folate was negatively correlated with hs-CRP, TNF-α, and IL-6 (P < 0.05). In multivariate analysis, there were significant associations between serum IL-6 or hs-CRP and MCI after adjusting for the confounding variables, however, the association between hs-CRP and MCI disappeared after further adjusting for serum folate. Further subgroup analysis revealed that the significant association between hs-CRP and MCI only existed in the low folate subgroup (< 7.0 μg/L; OR = 3.34, 95% CI: 1.05-10.64), not in the high folate subgroup (≥7.0 μg/L; OR = 2.16, 95% CI: 0.68-6.88) after adjusting for the confounding variables. CONCLUSIONS Serum IL-6 and hs-CRP were associated with the risk of MCI in Chinese patients with T2D. Serum folate might modify the association between serum hs-CRP and MCI in T2D patients.

Abstract
Background Contrast-induced nephropathy (CIN) is common after percutaneous coronary intervention (PCI) and always leads to a poor prognosis. Compared with conventional detection methods, either high-sensitivity C-reactive protein (hs-CRP) or procalcitonin have higher sensitivity and specificity for predicting CIN, but their combination has not been explored. This prospective study investigated the value of hs-CRP combined with procalcitonin for predicting CIN after PCI. Methods All patients undergoing PCI admitted to our hospital during the year 2016 were consecutively enrolled (n = 343). The patients received adequate hydration before PCI and 20 mg furosemide after the procedure. CIN was diagnosed by a 25% elevation in serum creatinine or ≥ 44.2 μmol/L (0.5 mg/dL) serum creatinine within 48 to 72 h after intravenous injection of contrast media. Results Patients with high hs-CRP or procalcitonin had higher rates of CIN relative to those patients with low values. For predicting CIN, hs-CRP combined with procalcitonin showed an area under the receiver operating characteristic curve of 0.67, with optimal cut-off value 0.0643610, and the sensitivity and specificity were higher than hs-CRP or procalcitonin alone. The logistic regression analysis showed that high-risk factors of CIN were acute myocardial infarction and highly elevated hsCRP and procalcitonin. Conclusions Prior to PCI, an elevation of the inflammatory biomarkers hsCRP and procalcitonin are a risk factor for postoperative CIN. This study suggests that the combination of hsCRP and procalcitonin is a better predictor of CIN after PCI then either hsCRP or procalcitonin alone. Trial registration number ChiCTR-IOR-14005250.

Abstract
Objective: To investigate the ability of white blood cell (WBC), procalcitonin (PCT) and high-sensitivity C-reactive protein (hs-CRP) in the super-elderly patients with bloodstream infection. Methods: It was a retrospective study. A total of 77 patients (≥85 years) admitted to the ICU of Peking Union Medical College Hospital from June, 2016 to December, 2017 were enrolled. The patients included 67 males and 10 females, with an age of 85-105 years and the average age was (92±5) years. According to the results of blood culture, patients were divided into positive blood culture group (n=50) and negative blood culture group (n=27). The data which obeyed normal distribution were compared with single sample t test between the two groups. Results: There was no significant difference in WBC level between the positive blood culture group and the negative blood culture group[12.4(7.8, 36.6)×10(9)/L vs 10.7(8.5, 18.7)×10(9)/L, U=0.109, P=0.124]. Compared to the positive blood culture group, the PCT level [2.6(0.8, 7.4)μg/L vs 1.5(0.6, 5.3)μg/L, U=3.015, P=0.004] and hs-CRP level [119(62, 220) mg/vs 54 (24, 80) mg/L, U=7.791, P<0.001] were significantly higher in the negative blood culture group. The ROC analysis showed that the area under the curves (AUC) of WBC, PCT and hs-CRP was 0.704(95%CI: 0.586-0.822, P<0.01), 0.896(95%CI: 0.829-0.964, P<0.01) and 0.864(95%CI: 0.778-0.949, P<0.01), respectively. The best cutoff value of PCT for discrimination of positive blood culture was 0.44 μg/L, which resulted in a sensitivity of 70.0% and a specificity of 92.6%. The best cutoff value of hs-CRP was 50.35 mg/L, which resulted in a sensitivity of 62.0% and a specificity of 88.9%. Conclusion: Compared to WBC, both PCT and hs-CRP have a better ability to predict bloodstream infection in the Super-elderly patients.

Abstract
BACKGROUND Assessing high-sensitivity C-reactive protein (hs-CRP) in relation to allergic endpoints can shed light on both the mechanisms of allergic disease development and early non-communicable disease prevention. However, only a few epidemiological studies so far have investigated the relationship in children and adolescents, and the results were mixed. OBJECTIVES We sought to examine the interrelation between hs-CRP levels and allergic outcomes using a larger population size and a longitudinal study design. METHODS Complete data were available on 1,955 participants from the 15-years follow-up of the 2 large population-based German birth cohorts - GINIplus and LISA. Serum hs-CRP concentrations were measured using the immunoturbidimetric high-sensitive assay. Six allergic endpoints were used - doctor-diagnosed asthma, doctor-diagnosed eczema, doctor-diagnosed allergic rhinitis, food sensitization, aeroallergen sensitization, and any sensitization. We used generalized estimation equation models to assess the associations between hs-CRP levels and allergic endpoints. RESULTS Our longitudinal analyses did not detect any significant association between hs-CRP levels and any of the studied allergic outcomes (e.g., asthma, eczema, allergic rhinitis, food sensitization, aeroallergen sensitization, and any sensitization). The results were consistent in a series of sensitivity analyses. CONCLUSIONS Our study suggests that there is no association between hs-CRP levels and any of the allergic endpoints in German adolescents. However, whether allergic diseases are inflammatory conditions and which markers might be most sensitive, remain to be confirmed in future studies.

Abstract
OBJECTIVE To assess the prevalence and determinants of food insecurity among people living with HIV (PLWH) in Pune, India and its association with biomarkers known to confer increased risks of morbidity and mortality in this population. DESIGN Cross-sectional analysis assessing food insecurity using the standardized Household Food Insecurity Access Scale. Participants were dichotomized into two groups: food insecure and food secure. Logistic regression models were used to assess associations between socio-economic, demographic, clinical, biochemical factors and food insecurity. SETTING Antiretroviral therapy (ART) centre of Byramjee Jeejeebhoy Government Medical College and Sassoon General Hospitals (BJGMC-SGH), Pune, a large publicly funded tertiary and teaching hospital in western India.ParticpantsAdult (≥18 years) PLWH attending the ART centre between September 2015 and May 2016 who had received ART for either ≤7d (ART-naïve) or ≥1 year (ART-experienced). RESULTS Food insecurity was reported by 40 % of 483 participants. Independent risk factors (adjusted OR; 95 % CI) included monthly family income <INR 5000 (~70 USD; 13·2; CI 5·4, 32·2) and consuming ≥4 non-vegetarian meals per week (4·7; 1·9, 11·9). High-sensitivity C-reactive protein (hs-CRP) ≥0·33 mg/dl (1·6; 1·04, 2·6) and d-dimer levels 0·19-0·31 µg/ml (1·6; 1·01, 2·6) and ≥0·32 µg/ml (1·9; 1·2, 3·2) were also associated with food insecurity. CONCLUSIONS More than a third of the study participants were food insecure. Furthermore, higher hs-CRP and d-dimer levels were associated with food insecurity. Prospective studies are required to understand the relationship between food insecurity, hs-CRP and d-dimer better.

The association between self-rated health and high-sensitivity C-reactive protein level: a cross-sectional and 5-year longitudinal study. BMC Public Health 2018; 18:1380. [PMID: 30558565 PMCID: PMC6297960 DOI: 10.1186/s12889-018-6251-6] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2018] [Accepted: 11/22/2018] [Indexed: 11/25/2022] Open
Abstract
Background Although self-rated health (SRH) independently predicts mortality, the biological background of this association remains unexplained. This study aimed to examine the association between SRH and serum high-sensitivity C-reactive protein (hsCRP) level. Methods Subjects were 899 participants aged 35–69 years (237 men and 662 women) in the Daiko Study, part of the Japan Multi-Institutional Collaborative Cohort Study. They were enrolled from 2008 to 2010. Of the subjects, 666 participated in a second survey 5 years later. Lifestyle factors and SRH were assessed using a self-administered questionnaire. Serum hsCRP level was measured using a latex-enhanced immunonephelometric assay. The association between SRH and serum hsCRP level was evaluated using a general linear model with covariates. We further longitudinally investigated whether higher serum hsCRP level at baseline predicts poor SRH after 5 years using an unconditional logistic regression model. Results A higher serum hsCRP level was significantly associated with poor SRH at baseline after adjusting for covariates (p for trend = 0.023). The age- and sex-adjusted odds ratio and 95% confidence interval (CI) for poor SRH after 5 years was 1.45 (95% CI: 0.76–2.78) for the highest tertile compared with the lowest tertile of serum hsCRP level at baseline with a significant linear trend (p for trend = 0.033), although the risk increase disappeared after adjustment for other covariates. Conclusions The present study demonstrated that poor SRH is cross-sectionally associated with higher serum hsCRP level. However, the longitudinal data did not support the relationship between serum hsCRP level at baseline and future SRH. Further longitudinal studies that include data on mortality and multiple inflammatory markers are warranted to elucidate the possible role of low-grade inflammation in the association between SRH and mortality risk.

Abstract
BACKGROUND It has been an established fact that diabetes mellitus (DM) is associated with lower levels of cognitive function and may be a risk factor for the development of mild cognitive impairment (MCI) and dementia. Most of these studies involved elderly diabetes patients and aging itself may contribute to cognitive impairment. Since a majority of the individuals with DM are between the ages of 40 and 59 years, it is crucial to determine the factors that contribute to cognitive impairment in these patients. So this study was done to correlate the various physical and metabolic parameters with MCI in young individuals with type 1 DM. MATERIALS AND METHODS In this cross-sectional study, 126 patients with type 1 DM underwent cognitive assessment by the Montreal Cognitive Assessment test and their cognitive levels were correlated with their HbA1c, lipid profile, and high-sensitivity C-reactive protein (hs-CRP). RESULTS The prevalence of MCI was 71.42%. MCI was significantly correlated with HbA1c, serum triglycerides, low-density lipoprotein, very low-density lipoprotein, and hs-CRP levels. The factors that were statistically insignificant were the duration of diabetes, body mass index, and high-density lipoprotein levels. CONCLUSION Cognitive impairment is seen even in type 1 DM patients. It should be considered along with the other complications of DM.

Abstract
Various immunologic and inflammatory factors are contributed to pathogenesis of Parkinson's disease (PD). High mobility group box-1 (HMGB1) is a protein that plays certain roles in inflammation, DNA repair, transcription, somatic recombination, cell differentiation, cell migration, neuronal development, and neurodegeneration. The aim of the present study was to evaluate the serum levels of HMGB1 and high-sensitivity C-reactive protein (hs-CRP) among patients with Parkinson's disease and healthy controls. This study includes 30 patients with PD and 30 healthy controls, matched sex, age, body mass index, and smoking status. HMGB1 and hs-CRP serum levels were compared between the groups. The diagnostic performance of HMGB1 and hs-CRP was evaluated with receiver operating characteristic (ROC) curve analysis. HMGB1 levels were significantly higher in PD patients than in controls. Hs-CRP levels were significantly higher in PD patients than in controls There was a moderate correlation between hs-CRP and HMGB1 levels in the patient group. The cut-off value of HMGB1 level for the prediction of PD was determined as 32.8 ng/mL with 80% sensitivity and 60% specificity (p = 0.006). The cut-off value of hs-CRP level for the prediction of PD was determined as 0.63 mg/L with 66.7% sensitivity and 77.7% specificity (p = 0.007). This study demonstrates for the first time the association between HMGB1, hs-CRP, and PD. We found that HMGB1 and hs-CRP levels to be significantly higher in the PD patients than in the normal controls. As a result of the ROC curve analysis, HMGB1 and hs-CRP levels may be fair markers in the diagnosis of PD.

Abstract
Background Secondhand smoke (SHS) exposure has adverse effects on the cardiovascular system. This study aimed to determine the effects of SHS on the cardiovascular disease biomarkers, namely the metabolic, inflammatory, and oxidative stress markers in healthy adult women. Methods This comparative cross-sectional study was conducted among healthy women. The cases included those women exposed to SHS, and the controls included those women not exposed to SHS. SHS exposure was defined as being exposed to SHS for at least 15 min for 2 days per week. Venous blood was taken to measure the metabolic markers (high molecular weight adiponectin, insulin level, insulin resistance, and nonesterified fatty acids), oxidative stress markers (oxidized low density lipoprotein cholesterol and 8-isoprostane), and inflammatory markers (high-sensitivity C-reactive protein and interleukin-6). A hair nicotine analysis was also performed. An analysis of covariance and a simple linear regression analysis were conducted. Results There were 101 women in the SHS exposure group and 91 women in the non-SHS exposure group. The mean (with standard deviation) of the hair nicotine levels was significantly higher in the SHS exposure group when compared to the non-SHS exposure group [0.22 (0.62) vs. 0.04 (0.11) ng/mg; P = 0.009]. No significant differences were observed in the high molecular weight adiponectin, insulin and insulin resistance, nonesterified fatty acids, 8-isoprostane, oxidized low density lipoprotein cholesterol, interleukin-6, and high-sensitivity C-reactive protein between the two groups. The serum high molecular weight adiponectin was negatively associated with the insulin level and insulin resistance in the women exposed to SHS. However, no significant relationships were seen between the high molecular weight adiponectin and nonesterified fatty acids, 8-isoprostane, oxidized low density lipoprotein cholesterol, high-sensitivity C-reactive protein in the SHS group. Discussion There were no significant differences in the metabolic, oxidative stress, and inflammatory markers between the SHS exposure and non-SHS exposure healthy women. A low serum level of high molecular weight adiponectin was associated with an increased insulin level and resistance in the women exposed to SHS.

Abstract
BACKGROUND AND AIMS Diet comprises factors with anti and pro-inflammatory potential that can contribute to modulate obesity-induced inflammation. We aimed to assess the association between food intake and high-sensitivity C-reactive protein (hsCRP) levels in adolescents. METHODS AND RESULTS A cross-sectional analysis of 991 adolescents aged 13 years old was conducted as part of the EPITeen cohort, Porto, Portugal. Food intake was assessed by a food frequency questionnaire and thirteen food groups were defined. Anthropometric assessment was performed and serum hsCRP was measured in a fasting blood sample. hsCRP concentrations above the 75th percentile were considered high. Logistic regression was fitted to estimate the association between the intake frequency of the food groups and hsCRP, stratified by BMI and adjusted for sex, parental education and total energy intake. Median (25-75th percentiles) hsCRP concentrations increased with increasing values of BMI [normal weight: 0.20 (0.10-0.50); overweight: 0.40 (0.20-0.80); obese: 1.10 (0.40-2.15) mg/l, p < 0.001]. After adjustment for sex, parental education and total energy intake, no statistically significant associations were found amongst normal weight and overweight participants. However, among obese individuals, having as reference the first frequency category (<1 per day), a higher frequency of vegetables/legumes intake showed a decreased odds of high hsCRP levels (OR: 0.10, 95%CI 0.03-0.38, 1-3 per day; and OR: 0.14, 95%CI 0.04-0.52, >3 per day). CONCLUSION Among participants with obesity-induced higher hsCRP levels, a higher frequency of vegetable/legume intake was inversely related to hsCRP.

Abstract
Objective: To investigate the association between high-sensitivity C-reactive protein (hs-CRP) and long-term outcomes in Chinese patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS) after drug-eluting stent (DES) implantation. Methods: A total of 4 815 consecutive NSTE-ACS patients who treated with DESs were included.Patients were divided into three groups: <1.00 mg/L, 1.00 to 2.99 mg/L and ≥3.00 mg/L, based on the level of hs-CRP on admission.Major adverse cardiovascular and cerebrovascular events (MACCE, including all-cause death, myocardial infarction, revascularization, in-stent thrombosis and stroke) were compared among groups during 2-year follow-up. Results: Patients with higher hs-CRP had more risk factors of cardiovascular events such as concomitant morbidities and multi-vessel lesions(68.5% vs 73.6% vs 76.2%, P<0.001). Higher hs-CRP value was associated with increased rates of MACCE (8.8% vs 11.2% vs 12.6%, P=0.003) and revascularization (6.5% vs 8.5% vs 9.8%, P=0.003). However, the rates of all-cause death, myocardial infarction, stroke, and stent thrombosis were comparable among groups(all P>0.05). Ongoing divergences in MACCE and revascularization among three groups were significant on Kaplan-Meier curves (both Log-rank P=0.003). Multivariable Cox regression analysis indicated that compared to hs-CRP<1.00 mg/L group, MACCE in the >3.00 mg/L group was increased by 42% [HR 1.42 (1.13-1.78), P=0.002]. Meanwhile, multivessel leisions, ejection fraction<50%, elevated white blood cell counts were also independent risk factors.CRP≥3.00 mg/L(HR 1.56, 95%CI 1.16-2.08, P=0.003, compared to <1.00 mg/L) and multivessel leisions were independent predictors of revascularization. Conclusions: (1)Patients with higher hs-CRP on admission have more risk factors of cardiovascular events.(2)Higher hs-CRP value is associated with increased rates of MACCE and revascularization.(3)Pre-procedural hs-CRP is an independent predictor of 2-year outcomes for Chinese NSTE-ACS patients treated with DESs.

Abstract
INTRODUCTION C-reactive protein (CRP) is an established marker for vascular inflammation and predictor of adverse cardiovascular events, but the prognostic value of preprocedural CRP in coronary artery disease (CAD) patients who have undergone percutaneous coronary intervention (PCI) remains controversial. Furthermore, the impact of CRP levels during follow-up in CAD patients after PCI on long-term adverse clinical outcomes is uncertain. We evaluated the association between high-sensitivity (hs)-CRP values at follow-up angiography and long-term clinical outcomes in CAD patients after coronary intervention. METHODS We prospectively enrolled 3507 consecutive CAD patients who underwent first PCI between 1997 and 2011 at our institution. We identified 2509 patients (71.5%) who underwent follow-up angiography (6-8 months after PCI). Of those, 1605 patients (45.8%) who had data available for hs-CRP at follow-up angiography were stratified into three groups according to tertiles of hs-CRP level at the time of follow-up angiography. The primary endpoint was composite of all-cause death and non-fatal acute coronary syndrome (ACS). RESULTS Median follow-up was 1716 days. The cumulative incidence of all-cause death and ACS differed significantly among groups (log-rank, p=0.0002). Multivariate Cox regression analysis showed that a higher hs-CRP level at follow-up angiography was associated with a greater risk of all-cause death and ACS [adjusted hazard ratio (HR) for all-cause death and ACS 2.14, 95% confidence interval (CI) 1.43-3.27, p=0.0002. CONCLUSION Elevated hs-CRP levels during follow-up were significantly associated with higher frequencies of adverse long-term clinical outcomes in patients with CAD after PCI.

Abstract
BACKGROUND As body fat composition and metabolism differ between men and women, we evaluated sex-related differences in the association among epicardial adipose tissue (EAT), secretome profile, and myocardial function of subjects with suspected metabolic syndrome. METHODS We evaluated 277 participants (men, n = 140; 56.1 ± 4.7 years) who underwent conventional echocardiography and two-dimensional speckle tracking from the Seoul Metabolic Syndrome cohort. EAT was measured from the right ventricular free wall perpendicular to the aortic annulus at end systole. Global longitudinal strain (GLS) was obtained from 18 apical segments. Apolipoprotein A1, apolipoprotein B, adiponectin, and high-sensitivity C-reactive protein (hs-CRP) levels were measured using immunoturbidimetry assay. RESULTS Mean age, body mass index, and hs-CRP level did not differ by sex. Waist circumference, fasting blood glucose level, and triglyceride/high-density lipoprotein cholesterol ratio were higher, and apolipoprotein AI and adiponectin levels were lower in men. No significant difference in mean EAT thickness was found (7.02 ± 1.81 vs. 7.13 ± 1.70 mm, p = 0.613). Men had a higher left ventricular (LV) mass index and lower GLS. EAT thickness was associated with hs-CRP level in men alone (ß = 0.206, p = 0.015). LV mass index (ß = 2.311, p = 0.037) and function represented by e' (ß = - 0.279, p = 0.001) and GLS (ß = - 0.332, p < 0.001) were independently associated with EAT thickness in men alone. CONCLUSIONS In middle-aged subjects with suspected metabolic syndrome, EAT was associated with inflammation represented by hs-CRP level, LV mass, and subclinical myocardial dysfunction only in men, suggesting that the inflammatory activity of EAT induced myocardial remodeling and dysfunction in middle-aged subjects but was attenuated in women. Trial registration NCT02077530 (date of registration: November 1, 2013).

Abstract
BACKGROUND Depression is a common comorbidity in psoriasis, and both conditions are associated with systemic inflammation. The efficacy of ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin (IL)-17A, was evaluated in patients with moderate-to-severe plaque psoriasis (psoriasis) and depressive symptoms that were at least moderately severe. METHODS Data were integrated from 3 randomized, double-blind, controlled phase 3 trials. At baseline and week 12, depressive symptoms and inflammation were assessed by the 16-item Quick Inventory of Depressive Symptomology - Self-Report (QIDS-SR16) and by a high-sensitivity assay of serum C-reactive protein (hsCRP), respectively. A subgroup of patients with at least moderately severe depressive symptoms at baseline (QIDS-SR16 total score ≥11) was analyzed. Improvement in psoriasis was assessed by the Psoriasis Area and Severity Index (PASI). RESULTS Approximately 10% of the overall psoriasis population had at least moderately severe depressive symptoms at baseline. At week 12, comorbid patients treated with ixekizumab had significantly greater improvements in their QIDS-SR16 total score (ixekizumab 80 mg every 2 weeks [Q2W], -7.1; ixekizumab 80 mg every 4 weeks [Q4W], -6.1) vs. placebo (-3.4) (p < 0.001, both comparisons) and higher rates of remission of depressive symptoms (ixekizumab Q2W, 45.2%; ixekizumab Q4W, 33.6%) vs. placebo (17.8%) (p ≤ 0.01, both comparisons). Patients treated with ixekizumab also had significant reductions in hsCRP and PASI compared to placebo. Etanercept treatment was not associated with significant improvements in depressive symptoms compared to placebo. CONCLUSIONS In this comorbid population, 12 weeks of ixekizumab therapy resulted in remission of depression for approximately 40% of patients and improved systemic inflammation as indicated by hsCRP.

Abstract
BACKGROUND/AIMS The mechanism, by which vitamin D influences inflammatory biomarkers in type 2 diabetes mellitus (T2DM), is not very well known. Thus, a meta-analysis of randomized controlled trials was conducted to assess the effect of vitamin D supplementation on some inflammatory biomarkers in T2DM subjects. METHODS We searched randomized controlled trials from PubMed and the Cochrane Library in October 2017 and conducted a meta-analysis to evaluate the effectiveness of vitamin D supplementation on high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). Either a fixed-effects or a random-effects model was used to calculate pooled effects. RESULTS We identified 13 studies that met our inclusion criteria. The results indicated that the vitamin D supplementation significant decreased the hs-CRP level by 0.45 μg/mL, whereas the vitamin D supplementation did not influence the TNF-α and IL-6. Subgroup analysis showed that vitamin D significantly lowered hs-CRP by 0.34 μg/mL among trials with a daily vitamin D dose ≤4,000 IU and by 0.31 μg/mL among trials with time of vitamin D supplementation > 12 weeks. CONCLUSIONS Vitamin D supplementation is beneficial for the reduction of hs-CRP inT2DM subjects but does not have a significant influence on TNF-α and IL-6 in T2DM subjects.

Abstract
Alopecia areata (AA) is a type of non-scarring, recurrent patchy loss of hair in hair-bearing areas and is mostly of autoimmune origin. Previous studies have suggested that some autoimmune diseases were found to be associated with vitamin D deficiency. The current study was designed to assess the levels of serum 25-hydroxy vitamin D and C-reactive protein in AA, as compared with controls and to further identify the association between vitamin D levels and disease severity in patients with AA. This cross-sectional study included 45 patients with AA and 45 healthy volunteers. Clinical and anthropometric parameters were recorded, according to a pre-designed proforma. Serum 25-hydroxy vitamin D and high-sensitivity C-reactive protein were estimated using ELISA kits. The severity of AA was determined using Severity of Alopecia Tool (SALT) score. We observed a significant rise in systemic inflammation as seen by elevated high-sensitive C-reactive protein levels and lowered 25-hydroxy vitamin D levels in patients with alopecia areata, compared to controls (p = 0.001). The levels of 25-hydroxy vitamin D showed a significant negative correlation with disease severity, while hs-CRP levels showed a significant positive correlation with disease severity (ρ = - 0.714, p = 0.001 and ρ = 0.818, p = 0.001). Our results suggest significant systemic inflammation and vitamin D deficiency in alopecia areata, more so with increasing disease severity. This gains particular importance in the treatment of alopecia areata in future, as supplementing vitamin D to AA patients would result in reducing the disease severity and inducing remission.

Abstract
BACKGROUND High-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. METHOD We 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. RESULTS A 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 (p for trend <0.001). Similarly, memory and executive function also declined faster with increasing quartiles of hs-CRP. CONCLUSIONS A 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
Autism spectrum disorder (ASD) affects about 1% of the world's population. Vitamin D is thought to be essential for normal brain development and modulation of the immune system. Worldwide about 1 billion people are affected by vitamin D deficiency. High-sensitivity C-reactive protein (hs-CRP), cytochrome P450 2E1 (CYP2E1) and 8-hydroxy-2'-deoxyguanosine (8-OH-dG) are biomarkers related to inflammation and oxidative stress. In the present study, these biomarkers were together with serum 25-hydroxyvitamin D (25(OH)D3) analyzed in 28 (mean age seven years) Saudi male patients with ASD. The study was conducted to determine if there is any relationship between vitamin D levels, the tested biomarkers and the presence and severity of ASD. The hope was to identify if these biomarkers may be useful for early ASD diagnosis. The Childhood Autism Rating Scale (CARS) and the Social Responsiveness Scale (SRS) were used to measure autism severity. The results of the ASD children were compared with 27 age and gender-matched neurotypical controls. The data indicated that Saudi patients with ASD have significantly lower plasma levels of 25(OH)D3 than neurotypical controls (38 ng/ml compared to 56 ng/ml, respectively; [P = 0.001]). Surprisingly, the levels of CYP2E1 were lower in the children with ASD than the neurotypical controls (0.48 ± 0.08 vs. 69 ± 0.07 ng/ml, respectively; P = 0.001). The ASD children also had significantly higher levels of hs-CRP (0.79 ± 0.09 vs. 0.59 ± 0.09 ng/ml, respectively; P = 0.001) and 8-OH-dG (8.17 ± 1.04 vs. 4.13 ± 1.01 ng/ml, respectively; P = 0.001, compared to neurotypical age and gender-matched controls. The values for hs-CRP and 8-OH-dG did not correlate [P < 0.001] with autism severity. There was found a relationship between autism severity on the CARS scale and the levels of 25(OH)D3 and CYP1B1. But this was not found for SRS. All four biomarkers seemed to have good sensitivity and specificity, but the sample size of the present study was too small to determine clinical usefulness. The findings also indicate that inadequate levels of vitamin D play a role in the etiology and severity of autism. Furthermore, the results of the present study suggest the possibility of using 25(OH)D3, CYP1B1, hs-CRP and 8-OH-dG, preferably in combination, as biomarkers for the early diagnosis of ASD. However, further research is needed to evaluate this hypothesis.
