Catharine R. Gale Daniel Baylis Cyrus Cooper Avan Aihie Sayer 《Age (Dordrecht, Netherlands)》2013,35(6):2493-2501
Cross-sectional studies show that higher blood concentrations of inflammatory markers tend to be more common in frail older people, but longitudinal evidence that these inflammatory markers are risk factors for frailty is sparse and inconsistent. We investigated the prospective relation between baseline concentrations of the inflammatory markers C-reactive protein (CRP) and fibrinogen and risk of incident frailty in 2,146 men and women aged 60 to over 90 years from the English Longitudinal Study of Ageing. The relationship between CRP and fibrinogen and risk of incident frailty differed significantly by sex (p for interaction terms <0.05). In age-adjusted logistic regression analyses, for a standard deviation (SD) increase in CRP or fibrinogen, odds ratios (95 % confidence intervals) for incident frailty in women were 1.69 (1.32, 2.17) and 1.39 (1.12, 1.72), respectively. Further adjustment for other potential confounding factors attenuated both these estimates. For an SD increase in CRP and fibrinogen, the fully-adjusted odds ratio (95 % confidence interval) for incident frailty in women was 1.27 (0.96, 1.69) and 1.31 (1.04, 1.67), respectively. Having a high concentration of both inflammatory markers was more strongly predictive of incident frailty than having a high concentration of either marker alone. In men, there were no significant associations between any of the inflammatory markers and risk of incident frailty. High concentrations of the inflammatory markers CRP and fibrinogen are more strongly predictive of incident frailty in women than in men. Further research is needed to understand the mechanisms underlying this sex difference. 相似文献

Methods The probing depth (PD), clinical attachment level (AL), C-reactive protein (CRP), interleukin-6 (IL-6) were determined. And then fifty-two elderly periodontitis patients underwent a standard phase of non-surgical periodontitis treatment (consisting of oral hygiene instructions and subgingival scaling and root planning). After three and six months, PD, AL, CRP and IL-6 were determined again and compared to the baseline. Results Six months after treatment, significant reductions in PD [(5.9±1.1) mm vs. (6.8±1.0) mm, P<0.05], AL [(1.3±0.9) mm vs.(8.4±1.1) mm, P<0.05], CRP [(1.5±0.2) mg/L vs. (2.0±0.3) mg/L, P<0.01] and IL-6 [(1.6±0.5) ng/L vs. (1.9±0.4) ng/L, P<0.05] were observed. Conclusions Treatment of chronic periodontitis can decrease the levels of serum inflammatory markers in elderly patients. 相似文献

Background
It is uncertain to what extent high C-reactive protein (CRP) concentrations reflect the presence of inflammatory conditions in the community.Methods
We evaluated 3782 Framingham Offspring Study participants (mean age 55 years; 52% women) free of baseline cardiovascular disease. Logistic regression models examined the prevalence of common inflammatory conditions by CRP categories, while a separate matched case-referent analysis evaluated the prevalence of uncommon inflammatory conditions. Cox models were used to assess the influence of common inflammatory conditions on relations between CRP and incident cardiovascular disease.Results
Common inflammatory conditions were reported by nearly half of the participants; these individuals were more likely to have markedly high CRP concentrations (>10 mg/L, P for trend = .001). In multivariable models, there were increased odds of having at least one common inflammatory condition with CRP concentrations of 1-3.0, 3.01-10, and >10 mg/L, compared with the referent category (<1 mg/L); the respective odds ratios with 95% confidence intervals were 1.41 (1.07-1.86), 1.45 (1.07-1.98), and 1.64 (1.09-2.47) in men, and 1.08 (0.82-1.43), 1.07 (0.80-1.44), and 1.38 (0.97-1.96) in women. In case-referent analyses, uncommon inflammatory conditions were more common in individuals with CRP >10 mg/L compared with those with CRP <1 mg/L (12.1% vs 6.6%; P = .0001). In multivariable models, higher CRP categories were not associated with incident cardiovascular disease, and with additional adjustment for inflammatory conditions, results remained unchanged.Conclusion
There is high prevalence of common and uncommon inflammatory conditions in individuals with high CRP concentrations. Higher CRP concentrations should be interpreted with caution in cardiovascular disease risk assessment. 相似文献6.

AIMS: Aim of the study was to investigate the association between various markers of systemic inflammation and a detailed history of smoking in a large representative sample of the general population. METHODS AND RESULTS: The effects of chronic smoking on white blood cell (WBC) count, fibrinogen, albumin, plasma viscosity (PV), and high-sensitivity C-reactive protein (CRP) were measured in 2305 men and 2211 women, age 25-74 years, participating in the third MONICA Augsburg survey 1994/95. In men, current smokers showed statistically significantly higher values for WBC count, fibrinogen, PV, and CRP, compared to never smokers, with intermediate, but only slightly increased values for ex-smokers and for occasional smokers. No consistent associations were seen with albumin. Duration of smoking was positively associated with markers of inflammation as were pack-years of smoking. Conversely, duration of abstinence from smoking was inversely related to these markers. Except for WBC count, no such associations were found in women. CONCLUSION: Data from this large representative population show strong associations between smoking and various markers of systemic inflammation in men. They also show that cessation of smoking is associated with a decreased inflammatory response, which may represent one mechanism responsible for the reduced cardiovascular risk in these subjects. 相似文献

Background and aimsPrevious studies have indicated that garlic consumption may be beneficial in improving inflammation. This systematic review and meta-analysis aimed to examine the effect of garlic supplementation on inflammatory biomarkers.MethodsPubMed/Medline, Scopus and ISI web of science were searched up to February 2019. Random effects model was used to calculate the overall effects on C-reactive protein (CRP), Interleukin-6 (IL-6), and Tumor necrosis factor- α (TNF-α).Results17 randomized controlled trials (RCTs) were included in the meta-analyses. Garlic supplementation significantly reduced the level of circulating CRP (P < 0.05), whereas it did not have any significant effect on IL-6 level (p > 0.05). Sub-group analysis showed that aged garlic extract (AGE) was able to reduce CRP and TNF-α significantly (P < 0.05).ConclusionsThis meta-analysis showed that supplementation with garlic could reduce the level of circulating CRP and AGE could reduce the level of TNF-α and CRP, whereas it had no significant effect on the IL-6 level. 相似文献

AimsTo explore the association of C-reactive protein (CRP) plasma levels with subsequent cognitive performance and decline among elderly individuals with pre-existing cardiovascular disease (CVD), and to assess the role of cerebrovascular indices in this relationship.MethodsCRP levels were measured in a subgroup of individuals with chronic CVD, who previously participated in a secondary prevention trial. Cognitive performance was evaluated 14.7 ± 1.9 and 19.9 ± 1.0 years after entry to the trial. A validated set of computerized cognitive tests was used (Neurotrax Computerized Cognitive Battery) to assess performance globally and in memory, executive function, visuospatial and attention domains. Linear regression and mixed models were used to assess the relationship of CRP plasma levels with cognitive scores and decline, respectively. In addition, we tested whether cerebrovascular reactivity, carotid intima media thickness and presence of carotid plaques modify these associations.ResultsAmong 536 participants (mean age at the first cognitive evaluation 72.6 ± 6.4 years; 95% males), CRP at the top tertile vs. the rest was associated with subsequent poorer performance overall (ß = −2.2 ± 1.0; p = 0.031) and on tests of executive function and attention (ß = −2.3 ± 1.1; p = 0.043 and ß = −2.0 ± 1.4; p = 0.047, respectively). Moreover, CRP levels were positively related to a greater decline in executive functions (ß = −2.4 ± 1.1; p = 0.03). These associations were independent of potential confounders and were not modified by cerebrovascular indices.ConclusionOur findings suggest that systemic chronic inflammation, potentially associated with underlying atherosclerosis, is related to cognitive impairment and decline two decades later, in elderly individuals with pre-existing CVD. 相似文献

Studies have shown disparate results in relation to the role of plasma concentrations of inflammation markers such as fibrinogen, cytokines, and cell adhesion molecules in acute coronary syndromes. The differentiation of primary versus secondary alterations of these markers in response to acute coronary syndromes is not clear. The aim of this study was to investigate the effect of soluble cell adhesion molecules and some inflammatory markers on coronary plaque instability. The prospective study consisted of 15 patients with stable angina pectoris (SAP), 16 with unstable angina pectoris (UAP), and 16 who had undergone percutaneous transluminal coronary angioplasty (PTCA). Blood samples were obtained from the SAP group on admission, from the UAP group at the early stage of pain onset within 6h of pain, and again after 12h of pain. Samples from the PTCA group were collected before, 2, 14h after the procedure. Soluble vascular cell adhesion molecule-1 (VCAM-1), endothelial selectin, interleukin-1 (IL-1) and interleukin-2 (IL-2), and C-reactive protein (CRP) were analyzed by enzyme-linked immunosorbent assay. CRP serum levels gradually increased although IL-2 gradually decreased in patients with UAP and PTCA. In addition, VCAM-1 levels were sharply decreased after the PTCA procedure. However, this value returned back to the preprocedure levels 14h after PTCA. Both CRP and IL-2 are directly involved in the triggering mechanisms of acute coronary events. 相似文献

BACKGROUND:
Coronary artery disease (CAD) occurs at an earlier age in South Asians compared with other ethnic groups. Infection and inflammation show a positive association with the disease.OBJECTIVE:
To investigate the association of infection and inflammatory markers with premature CAD in the Indian Atherosclerosis Research Study population.METHODS:
Antibody titres for Chlamydia pneumoniae, cytomegalovirus (CMV), Helicobacter pylori, herpes simplex virus and levels of interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP), fibrinogen and secretory phospholipase A2, were measured in 866 individuals (433 CAD patients and matched controls). All individuals were followed-up for recurrent cardiac events for four years. ANOVA was used to study the association of infection and inflammation with CAD.RESULTS:
The present study found that the odds of CAD occurrence was 2.42 (95% CI 1.26 to 4.64; P<0.008), with all four infections and increased in the presence of hsCRP (OR 4.67 [95% CI 1.43 to 15.25]); P=0.011). Only anti-CMV antibody levels were a significant risk factor for CAD occurrence (OR 2.23 [95% CI 1.20 to 4.15]; P=0.011) and recurrent cardiac events (OR 1.94 [95% CI 0.85 to 4.45]; P=0.015). Mean values of the inflammatory biomarkers IL-6 (P=0.035), fibrinogen (P=0.014), hsCRP (P=0.010) and secretory phospholipase A2 (P=0.002) increased with CMV antibody levels. Incorporating hsCRP and IL-6 in the risk prediction models significantly increased the OR to 2.56 (95% CI 1.16 to 5.63; P=0.019) with a c statistic of 0.826.CONCLUSIONS:
Pathogen burden, especially CMV infection in combination with inflammatory markers, is a significant predictor of CAD risk in the young Indian population. 相似文献20.
