The Relationship

C-reactive protein (CRP), a systemic marker of inflammation, is a risk factor for late life cognitive impairment and dementia, yet the mechanisms that link elevated CRP to cognitive decline are not fully understood. In this study we examined the relationship between CRP and markers of neuronal integrity and cerebral metabolism in middle-aged adults with intact cognitive function, using proton magnetic resonance spectrocospy. We hypothesized that increased levels of circulating CRP would correlate with changes in brain metabolites indicative of early brain vulnerability. Thirty-six individuals, aged 40 to 60, underwent neuropsychological assessment, a blood draw for CRP quantification, and 1H MRS examining N-acetyl-aspartate, myo-inositol, creatine, choline, and glutamate concentrations in occipito-parietal grey matter. Independent of age, sex and education, serum CRP was significantly related to higher cerebral myo-inositol/creatine ratio (F(4,31)=4.74,  P=0.004), a relationship which remained unchanged after adjustment for cardiovascular risk (F(5,30)=4.356, CRP β = 0.322, P=0.045). Because these biomarkers are detectable in midlife they may serve as useful indicators of brain vulnerability during the preclinical period when mitigating intervention is still possible.

The Relationship

ObjectiveTo study the relationship between serum C reactive protein (CRP) levels, genetic variation in the CRP gene and the prevalence, incidence and progression of radiographic osteoarthritis (ROA) in the Rotterdam Study-I (RS-I). A systematic review of studies assessing the relationship between osteoarthritis (OA) and CRP levels was also performed.MethodsThe association between CRP levels and genetic variation in the CRP gene and ROA was examined in 861 patients with hand OA, 718 with knee OA, 349 with hip OA and 2806 controls in the RS-I using one-way analysis of covariance and logistic regression, respectively. PubMed was searched for articles published between January 1992 and August 2009 assessing the relationship between CRP levels and OA.ResultsIn RS-I the prevalence of knee OA, but not hip OA or hand OA, was associated with 14% higher serum CRP levels compared with controls (p=0.001). This association disappeared after adjustment for age and especially body mass index (BMI) (p=0.33). Genetic variation of the CRP gene was not consistently associated with the prevalence, incidence or progression of OA within RS-I. The systematic review included 18 studies (including RS-I) on serum CRP levels and the prevalence, incidence or progression of OA. Consistently higher crude CRP levels were found in cases of prevalent knee OA compared with controls. No association was observed between serum CRP levels and the prevalence of knee OA following adjustment for BMI (n=3 studies, meta-analysis p value=0.61).ConclusionThere is no evidence of association between serum CRP levels or genetic variation in the CRP gene with the prevalence, incidence or progression of OA independent of BMI.

e14110 Background: Serum CRP was previously reported in myeloma to activate membrane bound Fcγ receptors which in turn activated Akt, and MAP kinase and inhibited caspase cascade activation resulting in increased tumour cell proliferation and inhibition of apoptosis. This study investigated the hypothesis that serum C-reactive protein (CRP) may activate signalling pathways in colorectal tumour cells. Methods: A cohort of 147 colorectal tumours was established and immunohistochemistry performed to assess protein expression of CRP, MAP kinase and Akt phosphorylated at serine 473 (pAkt). In addition, reverse transcriptase PCR for CRP mRNA expression was performed on 31 malignant colorectal specimens, 20 non-malignant colorectal specimens and 30 liver specimens. Results: No association between patient survival and tumour expression of CRP, pAkt and MAPK was observed, but serum CRP was independently associated with cancer-specific survival (p<0.001). When analysed according to tumour site, cytoplasmic CRP expression was associated with cancer specific survival in left sided tumours (p=0.022) and cytoplasmic pAkt was associated with cancer specific survival (p=0.029) in rectal tumours. No correlations were observed between serum CRP and tumour expression of CRP, pAkt and MAPK in the cohort as a whole or when subdivided by site. Conclusions: No link was established between serum CRP and signalling within the tumour. However, our results do support the concept of colorectal tumour heterogeneity, as different proteins were associated with patient survival depending on site. Further work is therefore required to elucidate the mechanisms underlying colorectal development and progression in tumour subtypes.

Background and Aims Increasing evidence suggests that elevated serum levels of C-reactive protein (CRP) are associated with poor survival in many malignant tumors. However, the prognostic value of CRP in advanced gastric cancer (AGC) remains uncertain. This study was undertaken to evaluate the significance of serum CRP as a biomarker of long-term survival in patients with AGC. Methods The serum CRP levels of AGC patients were analyzed for clinicopathological significance. Data were collected retrospectively for 244 patients treated between October 1, 2006 and September 30, 2013. The prognostic effect of serum CRP levels was evaluated. Results The baseline CRP level before chemotherapy was significantly associated with overall survival. The median survival was 351 days for patients with CRP ≥10 mg/L and 370 days for patients with CRP c10 mg/L (p = 0.033). Cox analysis revealed CRP to be an independent prognostic factor for overall survival. In the 93 patients whose baseline CRP was ≥10 mg/L, a cutoff point of 22% for the CRP declining rate provided optimum sensitivity and specificity for 1-year survival based on ROC curves. A CRP declining rate >22% was found to predict longer overall survival (410 days versus 299 days; p = 0.001). Conclusions Elevated serum CRP baseline levels before chemotherapy were associated with reduced overall survival in patients with AGC. The CRP declining rate was also associated with overall survival. The CRP baseline concentration before chemotherapy and CRP declining rate after chemotherapy may be used as novel, widely available and real-time independent prognostic and predictive markers of AGC.

AbstractObjectiveTo investigate the association of antioxidant intakes from diet and supplements with elevated blood C-reactive protein (CRP) and homocysteine (Hcy) concentrations.DesignA cross-sectional study. The main exposures were vitamins C and E, carotene, flavonoid and Se intakes from diet and supplements. Elevated blood CRP and Hcy concentrations were the outcome measures.SettingThe US population and its subgroups.SubjectsWe included 8335 US adults aged ≥19 years from the National Health and Nutrition Examination Survey 1999–2002.ResultsIn this US population, the mean serum CRP concentration was 4·14 (95 % CI 3·91, 4·37) mg/l. Intakes of vitamins C and E and carotene were inversely associated with the probability of having serum CRP concentrations >3 mg/l in multivariate logistic regression models. Flavonoid and Se intakes were not associated with the odds of elevated serum CRP concentrations. The mean plasma Hcy concentration was 8·61 (95 % CI 8·48, 8·74) μmol/l. Intakes of vitamins C, E, carotenes and Se were inversely associated with the odds of plasma Hcy concentrations >13 μmol/l after adjusting for covariates. Flavonoid intake was not associated with the chance of elevated plasma Hcy concentrations.ConclusionsThese results suggest that high antioxidant intake is associated with lower blood concentrations of CRP and Hcy. These inverse associations may be among the potential mechanisms for the beneficial effect of antioxidant intake on CVD risk mediators in observational studies.

Background: Patients critically ill with coronavirus disease-2019 (COVID-19) feature hyperinflammation, and the associated biomarkers may be beneficial for risk stratification. We aimed to investigate the association between several biomarkers, including serum C-reactive protein (CRP), procalcitonin (PCT), D-dimer, and serum ferritin, and COVID-19 severity. Methods: We performed a comprehensive systematic literature search through electronic databases. The outcome of interest for this study was the composite poor outcome, which comprises mortality, acute respiratory distress syndrome, need for care in an intensive care unit, and severe COVID-19. Results: A total of 5350 patients were pooled from 25 studies. Elevated CRP was associated with an increased composite poor outcome [risk ratio (RR) 1.84 (1.45, 2.33), p < 0.001; I2: 96%] and its severe COVID-19 (RR 1.41; I2: 93%) subgroup. A CRP ⩾10 mg/L has a 51% sensitivity, 88% specificity, likelihood ratio (LR) + of 4.1, LR- of 0.5, and an area under curve (AUC) of 0.84. An elevated PCT was associated with an increased composite poor outcome [RR 3.92 (2.42, 6.35), p < 0.001; I2: 85%] and its mortality (RR 6.26; I2: 96%) and severe COVID-19 (RR 3.93; I2: 63%) subgroups. A PCT ⩾0.5 ng/ml has an 88% sensitivity, 68% specificity, LR+ of 2.7, LR- of 0.2, and an AUC of 0.88. An elevated D-dimer was associated with an increased composite poor outcome [RR 2.93 (2.14, 4.01), p < 0.001; I2: 77%], including its mortality (RR 4.15; I2: 83%) and severe COVID-19 (RR 2.42; I2: 58%) subgroups. A D-dimer >0.5 mg/L has a 58% sensitivity, 69% specificity, LR+ of 1.8, LR- of 0.6, and an AUC of 0.69. Patients with a composite poor outcome had a higher serum ferritin with a standardized mean difference of 0.90 (0.64, 1.15), p < 0.0001; I2: 76%. Conclusion: This meta-analysis showed that an elevated serum CRP, PCT, D-dimer, and ferritin were associated with a poor outcome in COVID-19.

Background: Elevated plasma homocysteine (Hcy) and high-sensitivity C-reactive protein (hsCRP) levels are independent risk factors for cardiovascular diseases. However, it is unclear whether the coexistence of these conditions accelerates the risk of arterial stiffness. Our study aimed to evaluate the association of combined Hcy and hsCRP with arterial stiffness in Chinese middle-aged adults. Material/Methods: We conducted a 12-year longitudinal study in 220 individuals in Hanzhong, China, from 2005 to 2017. The average age at follow-up was 41.83 ± 3.10 years. Demographic information, medical history, anthropometric measurements, and blood pressure as well as urine and fasting blood samples, including Hcy, hsCRP, and brachial-ankle pulse wave velocity (baPWV) were measured and analyzed. Results: BaPWV levels showed a linear growth trend with the increasing of hsCRP (p for trend <0.01). The ORs in the highest quartile compared to the lowest quartile were 1.985 (95% CI 0.776–5.077; p = 0.152) and 3.960 (95% CI 1.468–10.684; p= 0.007) for Hcy and hsCRP, respectively. When Hcy and hsCRP were combined, subjects in both the highest quartile of Hcy and hsCRP (Hcy ≥15.50 μmol/L and hsCRP ≥0.82 μmol/L) had a 12.68-fold increased risk of developing arterial stiffness at the 12-year follow-up compared to those in the lowest quartile of Hcy and hsCRP (Hcy ≤9.91 μmol/L and hsCRP ≤0.19 μmol/L) after adjusting for potential confounders. Conclusions: The present study demonstrated that the combination of elevated serum Hcy and hsCRP may contribute to an increased risk of arterial stiffness.
