<h4>Background</h4>We performed a cohort study to evaluate the association between the CRP trajectory and incident diabetes in Chinese adults.<h4>Methods</h4>Included were 6439 adults (4111 men and 2249 women; aged 46.6 ± 11.9 years). The concentration of high sensitivity CRP (hs-CRP) was measured in 2013 (baseline), 2014, and 2015. The hs-CRP trajectory was identified based the above three measurements by latent mixture modeling. Incident diabetes cases were diagnosed by fasting blood glucose ( ...[more]

Project description:ObjectivePrevious studies on the association between hs-CRP and incident type 2 diabetes among African Americans have been inconclusive. We examined the association between hs-CRP and incident diabetes in a large African American cohort (Jackson Heart Study).Research design and methodshs-CRP was measured in 3,340 participants. Incident diabetes was defined by fasting glucose ≥126 mg/dL, physician diagnosis, use of diabetes drugs, or A1C ≥6.5% (48 mmol/mol) at follow-up. Cox regression was used to estimate hazard ratios (HRs) for incident diabetes, adjusting for age, sex, education, diabetes family history, alcohol, HDL, triglycerides, hypertension status, hypertension medications, physical activity, BMI, HOMA-insulin resistance (HOMAIR), and waist circumference.ResultsParticipants (63% women) were aged 53.3 ± 12.5 years. During a median follow-up of 7.5 years, 17.4% developed diabetes (23.1/1,000 person-years, 95% CI 21.3-25.1). After adjustment, the HR (hs-CRP third vs. first tertile) was 1.64 (95% CI 1.26-2.13). In separate models, further adjustment for BMI and waist circumference attenuated this association (HR 1.28 [95% CI 0.97-1.69] and 1.35 [95% CI 1.03-1.78, P < 0.05 for trend], respectively). Upon adding HOMAIR in the models, the association was no longer significant. In adjusted HOMAIR-stratified analysis, the hs-CRP-diabetes association appeared stronger in participants with HOMAIR <3.0 compared with HOMAIR ≥3.0 (P < 0.0001 for interaction). The association was also stronger among nonobese participants, although not significant when adjusted for HOMAIR.ConclusionsLow-grade inflammation, as measured by hs-CRP level, may have an important role in the development of diabetes among African Americans with a lesser degree of insulin resistance.

Project description:to determine the association of high sensitivity C-reactive protein (HsCRP) levels with a risk of mobility disability and decline in older adults with and without vascular disease.prospective cohort.community-residing population.six hundred and twenty-four adults age 70 and older (62% women) with gait and HsCRP assessments.incident mobility disability (velocity <70 cm/s) and annual rates of decline on gait velocity.elevated HsCRP levels (? 3 mg/l) at baseline present in 224 of the 624 eligible subjects was associated with a faster annual decline in gait velocity of 0.91 cm/s (P=0.02). Subjects with elevated HsCRP levels had increased risk of mobility disability (hazard ratio: 1.85, 95% CI: 1.09-3.14). Each one-unit increase in log HsCRP levels in the 406 subjects without prevalent mobility disability was associated with increased risk of mobility disability (hazard ratio: 1.33, 95% CI: 1.05-1.68). The association of baseline HsCRP levels with mobility disability and decline was stronger in the 224 individuals without vascular disease. The associations were not significant in the 400 subjects with vascular disease.HsCRP levels predict mobility disability and accelerated decline in walking speed in older adults. These associations were stronger in those without vascular disease.

Project description:BackgroundAlkaline phosphatase (ALP) has been suggested to be associated with cardiovascular disease (CVD) risk, however, important aspects of the association, such as shape and independence from established risk factors, have yet to be characterized in detail. We assessed the association of ALP with CVD risk and determined its utility for CVD risk prediction.MethodsAlkaline phosphatase activity was measured at baseline in the PREVEND prospective cohort involving 6,974 participants aged 28-75 years without pre-existing CVD. Hazard ratios (95% confidence intervals [CI]) and measures of risk discrimination and reclassification were assessed.ResultsDuring a median follow-up of 10.5 years, 737 participants developed CVD. Serum ALP was correlated with several risk markers for CVD, with strongest correlations for age (r = 0.30; P < 0.001), gamma-glutamyltransferase (r = 0.26; P < 0.001), and C-reactive protein (CRP) (r = 0.25; P < 0.001). There was a non-linear "J-shaped" relationship between ALP and CVD risk. In analyses adjusted for conventional risk factors, the hazard ratio (95% CI) for CVD in a comparison of the top quintile versus bottom quintiles 1-4 of ALP values was 1.34 (1.14 to 1.56; P<0.001), which persisted after additional adjustment for potential confounders 1.33 (1.13 to 1.55; P<0.001). However, the association was somewhat attenuated after adjustment for CRP 1.24 (1.05 to 1.45; P=0.009). Addition of information on ALP to a CVD risk prediction model containing established risk factors did not improve the C-index or net reclassification.ConclusionsAvailable evidence suggests a non-linear association between ALP activity and CVD risk, which is partly dependent on CRP. Taking account of conventional risk factors, additional information on ALP does not improve CVD risk assessment.

Project description:Recent longitudinal work suggests that weight change is an important risk factor for inflammation across the full range of BMI. However, few studies have examined whether the risk of inflammation differs by patterns of weight gain over time. Using latent class trajectory analysis, we test whether patterns of weight gain are associated with elevated high-sensitivity C-reactive protein (hs-CRP 2-10 mg/L).Data come from China Health and Nutrition Survey (CHNS) participants (n=5536), aged 18 at baseline to 66 years in 2009, with measured weight over 18 years. Latent class trajectory analysis was used to identify weight-change trajectories in 6 age and sex strata. Multivariable general linear mixed-effects models fit with a logit link were used to assess the risk of elevated hs-CRP across weight trajectory classes. Models were fit within age and sex strata, controlling for baseline weight, adult height, and smoking, and included random intercepts to account for community-level correlation. Steeper weight-gain trajectories were associated with greater risk of elevated hs-CRP compared to more moderate weight-gain trajectories in men and women. Initially high weight gain followed by weight loss was associated with lower risk of elevated hs-CRP in women aged 18 to 40.Latent class trajectory analysis identified heterogeneity in adult weight change associated with differential risk of inflammation independently of baseline weight and smoking. These results suggest that trajectories of weight gain are an important clinical concern and may identify those at risk for inflammation and the development of cardiometabolic disease.

Project description:Aims/introductionDyslipidemia plays a critical role in the pathogenesis of metabolic syndrome and diabetes. Evidence has increasingly shown that the ratio of low- to high-density lipoprotein cholesterol (LDL-C/HDL-C) is a novel marker for increased risk of insulin resistance and cardiovascular diseases. However, the correlation between the LDL-C/HDL-C ratio and diabetes risk is rarely reported. This is the first study to investigate the association between the LDL-C/HDL-C ratio and new-onset diabetes in a large community-based cohort.Materials and methodsIn this retrospective cohort study, a total of 116,661 adults without baseline diabetes were enrolled. Participants were stratified into four groups based on LDL-C/HDL-C ratio quartiles. The outcome of interest was new-onset diabetes.ResultsDuring a median follow-up period of 2.98 years, 2,681 (2.3%) new diabetes cases were recorded. The total cumulative incidence of diabetes progressively increased alongside LDL-C/HDL-C ratio quartiles (0.31, 0.43, 0.68 and 0.88%, respectively, P-value for trend <0.001). After adjusting for potential confounders, using the lowest quartile of the LDL-C/HDL-C ratio as the reference, the risk of diabetes increased with LDL-C/HDL-C ratio quartiles (P-value for trend <0.001); in particular, from the second to fourth quartile, hazard ratios were 1.18 (95% confidence interval 0.87-1.59), 1.42 (95% confidence interval 1.07-1.90) and 1.92 (95% confidence interval 1.43-2.59), respectively. The results were also robust to challenges in multiple sensitivity analyses.ConclusionsAmong the Chinese population, elevated LDL-C/HDL-C ratio might be an independent risk factor for new-onset diabetes.

Project description:Clonal hematopoiesis of indeterminate potential (CHIP) is predictive of hematological cancers and cardiovascular diseases, but the etiology of CHIP initiation and clonal expansion is unknown. Several lines of evidence suggest that proinflammatory cytokines may favor mutated hematopoietic stem cell expansion. To investigate the potential link between inflammation and CHIP, we performed targeted deep sequencing of 11 genes previously implicated in CHIP in 1887 subjects aged >70 years from the Montreal Heart Institute Biobank, of which 1359 had prior coronary artery disease (CAD), and 528 controls did not. We assessed association of CHIP with log transformed high-sensitivity C-reactive protein (hs-CRP), a validated biomarker of inflammation. CHIP was identified in 427 of the 1887 subjects (22.6%). CHIP mutations were more frequently identified in DNMT3A (11.6%) and TET2 (6.1%), with a higher proportion of TET2 mutations occurring in controls than in patients with CAD (9.0% vs 4.9%, P < .001). CHIP carriers had 21% higher hs-CRP levels compared with their noncarrier counterparts (e? = 1.21, 95% confidence interval [CI]: 1.08 to 1.36; P = .001). A similar effect was observed in the subgroup of patients with known CAD (e? = 1.22, 95% CI: 1.06 to 1.41; P = .005). These findings confirm the association between inflammation and CHIP. This association may open investigational avenues aimed at documenting mechanisms linking inflammation to clonal progression and ultimately supports prevention interventions to attenuate CHIP's impact on cardiovascular disease and cancer.

Project description:BackgroundTo investigate single and joint associations of body mass index (BMI) and serum high-sensitivity C-reactive protein (hsCRP) with death.MethodsThe study included 1871 coronary artery disease (CAD) patients aged 40-85 year-old recruited from 2008 to 2011. Cox regression models were used to estimate the association of BMI and hsCRP with mortality. The data was analyzed in 2014.ResultsDuring 3.1 years follow-up, 141 deaths were recorded, 110 died of cardiovascular disease (CVD). After adjustment of major CVD risk factors, there was a J-shaped association between BMI and all-cause and CVD mortality, and a positive association between hsCRP and mortality. The J-shaped association of BMI with mortality was present among patients who never smoked or with elevated hsCRP (?3.0 mg/L). Compared with overweight (BMI 24-27.9 kg/m2) patients with normal hsCRP (<3.0 mg/L), obese patients (BMI?28 kg/m2) with elevated hsCRP had a 3.41-fold risk of all-cause mortality (95% CI 1.49-7.80) and a 3.50-fold risk of CVD mortality (1.40-8.75), lean patients (BMI<24 kg/m2) with elevated hsCRP concentration had a 2.54-fold risk of all-cause mortality (1.36-4.74) and a 2.36-fold risk of CVD mortality (1.19-4.70).ConclusionsThe association pattern between baseline BMI and mortality changed among different baseline hsCRP concentrations, indicating that low-grade inflammation may be related to BMI and secondary prognosis of CAD.

Project description:BACKGROUND:A hospitalized-based cohort study suggested that elevated C-reactive protein (CRP) levels are associated with radiographic sacroiliitis progression in ankylosing spondylitis (AS) patients. However, data from community-based populations are limited. OBJECTIVE:We sought to determine the association between elevated CRP levels and AS diagnosis in a prospective community-based study of 129,681 Chinese adults over a follow-up period of 8 years. METHODS:We measured the plasma CRP concentration at baseline and every 2 years thereafter with the high-sensitivity (hs)-CRP test. Incident AS cases were confirmed on the basis of modified New York diagnostic criteria after review of medical records. We used Cox proportional-hazard models to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for AS on the basis of hs-CRP concentrations, adjusting for age, sex, education, income, cigarette smoking, alcohol intake, physical activity, body mass index, blood-pressure status, blood glucose status, total cholesterol, history of cardiovascular disease, and use of antihypertensives, lipid-lowering agents, and aspirin. RESULTS:During 1,033,609 person-years (average 7.97 ± 1.36 years per person) of follow-up, we identified 55 incident AS cases. Baseline hs-CRP was positively associated with the risk of future AS. Compared with hs-CRP <1 mg/L, the HR was 1.28 (95% CI 0.54-3.08) for hs-CRP of 1.00-2.99 mg/L, 4.71 (95% CI 2.26-9.81) for hs-CRP of 3.00-9.99 mg/L, and 19.8 (95% CI 9.6-40.9) for hs-CRP ?10.00 mg/L (P-trend <0.001) after adjustment for potential confounders. We found similar results after excluding AS cases that occurred in the first 2 years of follow-up, and using the cumulative average hs-CRP concentration as a predictor. CONCLUSION:This is the first study in a community-based cohort to demonstrate that CRP plasma concentrations predict the risk of future AS, thus providing a test that is easy to routinely perform in the clinic to assess for AS risk.

Project description:BACKGROUND:Obesity-associated inflammation promotes metabolic dysfunction. However, it is unclear how different inflammatory biomarkers predict dysregulation in specific tissues/organs, particularly adipose tissue. OBJECTIVE:The aim of our study was to examine whether GlycA, a nuclear magnetic resonance-measured biomarker of inflammation, is a better predictor of insulin-suppressible lipolysis and other measures of metabolic dysfunction compared with high-sensitivity C-reactive protein (hsCRP) in human obesity. METHODS:This was a cross-sectional study of 58 nondiabetic adults with obesity (body mass index: 39.8 ± 7.0 kg/m2, age 46.5 ± 12.2 years, 67.2% female) who underwent a frequently sampled intravenous glucose tolerance test in the fasted state. Noninsulin-suppressible (l0), insulin-suppressible (l2), and maximal (l0+l2) lipolysis rates, as well as insulin sensitivity and acute insulin response to glucose, were calculated by minimal model analysis. Nuclear magnetic resonance was used to measure GlycA. Body composition was determined by dual-energy X-ray absorptiometry. RESULTS:GlycA was strongly correlated with hsCRP (r = +0.46; P < .001). GlycA and hsCRP were positively associated with l2, l0+l2, and fat mass (Ps < .01). In linear regression models accounting for age, race, sex, and fat mass, GlycA remained significantly associated with l2 and l0+l2 (Ps < .05), whereas hsCRP did not (Ps ? .20). Neither GlycA nor hsCRP was associated with l0, insulin sensitivity, or acute insulin response to glucose. CONCLUSIONS:GlycA was associated with elevated lipolysis, independent of adiposity, in adults with obesity. Our findings suggest that GlycA and hsCRP have distinct inflammation-mediated metabolic effects, with GlycA having a greater association with adipose tissue dysfunction. Further studies are warranted to investigate the mechanisms underlying these associations.

Project description:BackgroundSingle measurements of elevated high-sensitivity C-reactive protein (hs-CRP) are associated with increased risk of diabetes, cardiovascular disease, and mortality. Large increases or sustained elevations in hs-CRP may be associated with even greater risk of these outcomes. The objective of this study was to characterize the association of 6-year change in hs-CRP with incident diabetes, incident cardiovascular events (heart disease, stroke, and heart failure), and mortality.MethodsWe included 10,160 ARIC participants with hs-CRP measured at visits 2 (1990-1992) and 4 (1996-1998). Change in hs-CRP was categorized as sustained low/moderate (<3 mg/L at both visits), decreased (≥3 mg/L at visit 2 and <3 mg/L at visit 4), increased (<3 mg/L at visit 2 and ≥3 mg/L at visit 4), and sustained elevated (≥3 mg/L at both visits). Cox proportional hazards models were used to assess the association of 6-year change in hs-CRP with incident diabetes, cardiovascular events, and death during ~15 years after visit 4.ResultsCompared with persons with sustained low/moderate hs-CRP, those with increased or sustained elevated hs-CRP had an increased risk of incident diabetes (hazard ratios [95% CIs] 1.56 [1.38-1.76] and 1.39 [1.25-1.56], respectively), whereas those with deceased hs-CRP did not. Persons with sustained elevated hs-CRP had an increased risk of coronary heart disease, ischemic stroke, heart failure, and mortality (hazard ratios [95% CIs] 1.51 [1.23-1.85], 1.70 [1.32-2.20], 1.60 [1.35-1.89], and 1.52 [1.37-1.69], respectively) compared with those with sustained low/moderate hs-CRP. Associations for sustained elevated hs-CRP were greater than for those with increased hs-CRP over 6 years.ConclusionsLarge increases or sustained elevations in hs-CRP over a 6-year period were associated with a subsequent increased risk of diabetes, and persons with sustained elevations in hs-CRP were at the highest risk for cardiovascular disease and mortality. Two measurements of hs-CRP are better than one for characterizing risk, and large increases are particularly prognostic.
