Objective To describe the distribution of plasma high sensitivity C-reactive protein (hsCRP) and explore the relationship between hsCRP and metabolic risk factors among residents living in longevity areas of China. Methods 268 individuals aged between 40 and 59 years and 506 individuals aged over 90 years were selected from 5 longevity areas of China to participate in a cross section longitudinal cohort study. The participants were interviewed with general health related questionnaire to collect their demographic, behavioral and lifestyle data, as well as their chronic conditions, and meanwhile their physical and biomedical parameters including waist circumference (WC), blood pressure (BP), hsCRP, plasma lipids, and fasting blood glucose (FBG) were measured. Results The median of hsCRP was 0.99 mg/L in the middle-aged group and 2.76 mg/L in the oldest old group. No significant gender difference was observed between the above two groups. Among the oldest old individuals, 36.56% had an hsCRP level 〉3.0 mg/L. The prevalence of high hsCRP was 26.79% in the middle-aged group. The results of stepwise multiple linear regression analyses showed that HDL-C was independently associated with In (hsCRP) concentration in the middle-aged group, whereas In (TG), HDL-C and FBG were correlated after adjustment for gender, study site, smoking, drinking, education and BMI in the oldest old group. Conclusion HDL-C is a stronger predictor of elevated hsCRP than other metabolic factors in the middle-aged population. For the oldest old persons, high TG, low HDL-C, and FBG predict elevated plasma hsCRP.

Host-mediated lung inflammation is present,1 and drives mortality,2 in critical illness caused by *** genetic variants associated with critical illness may identify mechanistic targets for therapeutic development.3 Here we report the results of the GenOMICC(Genetics Of Mortality In Critical Care)genome-wide association study(GWAS)in 2244 critically ill Covid-19 patients from 208 UK intensive care units(ICUs).We identify and replicate novel genome-wide significant associations,on chr12q24.13(rs10735079,p=1.65[Formula:see text]10-8)in a gene cluster encoding antiviral restriction enzyme activators(OAS1,OAS2,OAS3),on chr19p13.2(rs2109069,p=2.3[Formula:see text]10-12)near the gene encoding tyrosine kinase 2(TYK2),on chr19p13.3(rs2109069,p=3.98[Formula:see text]10-12)within the gene encoding dipeptidyl peptidase 9(DPP9),and on chr21q22.1(rs2236757,p=4.99[Formula:see text]10-8)in the interferon receptor gene *** identify potential targets for repurposing of licensed medications:using Mendelian randomisation we found evidence in support of a causal link from low expression of IFNAR2,and high expression of TYK2,to life-threatening disease;transcriptome-wide association in lung tissue revealed that high expression of the monocyte/macrophage chemotactic receptor CCR2 is associated with severe *** results identify robust genetic signals relating to key host antiviral defence mechanisms,and mediators of inflammatory organ damage in *** mechanisms may be amenable to targeted treatment with existing ***-scale randomised clinical trials will be essential before any change to clinical practice.
