Additive effect of interleukin-6 and C-reactive protein (CRP) single nucleotide polymorphism on serum CRP concentration and other cardiovascular risk factors

BACKGROUND: Serum C-reactive protein (CRP) levels, closely associated with cardiovascular disease (CVD) risk are influenced by CRP or interleukin-6 (IL-6) single nucleotide polymorphism (SNPs). However, it is still controversial. Therefore, we investigated the association of IL-6/CRP SNPs and serum CRP levels or other CVD risk factors in healthy adult Korean men. METHODS: In healthy adult men (age>or=20 years, n=677), we genotyped IL-6-572C>G and CRP SNPs (-717G>A, 1444C>T, 2147A>G) and measured anthropometric parameters, lipid profile, serum levels of CRP and IL-6 and insulin resistance. RESULTS: At IL-6-572C>G (n=677), subjects with G/G genotype (n=42) showed higher concentrations of CRP (P=0.027) and IL-6 (P=0.028) as compared with C allele carriers after age-adjustment (C/C: n=371, C/G: n=264). Fasting insulin and homeostatis model assessment insulin resistance (HOMA-IR) were also higher in G/G genotype. However, there were no significant differences in other metabolic biomarkers. Among 677 study subjects, 676 were genotyped at CRP-717G>A (G/G: n=513, G/A: n=150, A/A: n=13), 672 at CRP+1444C>T (C/C: n=580, C/T: n=85, T/T: n=7), and 668 at CRP+2147A>G (A/A: n=273, A/G: n=296, G/G: n=99). There were no significant differences in CRP concentrations and other markers related to CVD risk according to each CRP SNP genotype. However, we could find the additive gene-gene interaction between IL-6-572C>G and CRP SNPs on CRP concentration; subjects with the 'G/G' at IL-6-572 showed the highest CRP levels when they have variant allele at CRP SNPs after adjusted for age, body mass index, cigarette smoking and alcohol drinking (-717G>A: F=7.806, P=0.005; CRP+1444C>T: F=8.398, P=0.004; and CRP+2147A>G: F=7.564, P=0.006, respectively) Particularly, G allele carriers at CRP+2147A>G in subjects with IL-6-572G/G showed highest HOMA-IR (F=9.092, P=0.003). CONCLUSION: The present data showed that serum CRP levels and other CVD risk factors appeared more influenced by IL-6-572C>G rather than CRP SNPs (-717G>A, 1444C>T, and 2147A>G), however CRP levels and insulin resistance may be additively affected by IL-6-572 and CRP SNP, particularly when subjects with G/G genotype at IL-6-572 have allele variant at CRP SNPs.     

Meal induced increase in serum triglycerides has no effect on lymphocyte response to mitogens

The effect of a standardized heavy meal on the lymphocyte transformations induced by phytohaemagglutinin (PHA), concanavalin A (Con A) and PPD tuberculin was studied. The meal significantly increased the serum triglycerides (P less than 0.01), while it had no effect on cholesterol or high density lipoprotein-cholesterol levels. The increase in serum triglycerides did not affect lymphocyte transformation induced by phytohaemagglutinin or concanavalin A in whole blood microcultures. A slight decrease was observed when lymphocytes were stimulated with one out of three concentrations of PPD tuberculin (P less than 0.05). However, there was no correlation with the increase of triglycerides and decrease in lymphocyte transformation. Our observation shows that physiological changes in serum triglycerides do not affect the capacity of lymphocytes to respond to mitogenic stimulation, and the whole blood micromethod for lymphocyte stimulation to screen the capacity of cell-mediated immunity does not depend on the meal schedule of the patients.

Biomarkers of liver fibrosis: clinical translation of molecular pathogenesis or based on liver-dependent malfunction tests

BACKGROUND: Fibrosis is the excessive deposition and histological redistribution of extracellular matrix (ECM) in the tissue as consequence of chronic liver damage. It leads to progressive liver insufficiency, portal hypertension and ultimately to cirrhosis and primary liver cell carcinoma. There is a strong demand for reliable, organ- and disease-specific, non-invasive biomarkers of fibrosis and fibrogenesis to replace or to complement the invasive method of needle biopsy, which is afflicted with a high degree of sampling error. METHODS: A systematic literature search was performed using electronic databases and reference lists of relevant publications to ascertain studies with non-invasive biomarkers of liver fibrosis. RESULTS: Two classes of serum biomarkers can be differentiated: Class I markers are those, which reflect ECM turnover (fibrogenesis and fibrolysis) and/or fibrogenic cell changes, mainly of hepatic stellate cells, which are the dominant profibrogenic cell type in liver. They are mostly cost intensive, single laboratory tests and derive from the translation of fibrogenic mechanisms into clinical application. Examples are procollagen peptides, hyaluronan, and laminin. Class II biomarkers are based on algorithmic evaluation of commonly observed functional alterations of the liver that do not necessarily reflect ECM metabolism and/or fibrogenic cell changes. About 20 numerical scores or indices are reported for parameters, which are mostly routine laboratory tests and frequently multiparametric (panels). Among them fibrotest, hepascore, ELF-score have reached limited clinical application. CONCLUSIONS: Up to now the impact of both classes of biomarkers for diagnosis and monitoring of fibrosis, fibrogenesis, and fibrolysis is limited. They cannot replace needle biopsy but some of them might be complementary in follow-up studies. Innovative methods like proteomics and glycomics to establish fibrosis-specific serum protein and glycosylation patterns, respectively, might have a high potential for diagnosis and monitoring of fibrogenesis.     

血清脂质、脂蛋白胆固醇和载脂蛋白在冠心病中的临床意义

目的研究冠心病患者的血清脂质、脂蛋白胆固醇和载脂蛋白的变化、辨别力和诊断价值。方法测定64例冠心病(CHD)患者和60例正常人的血脂、脂蛋白胆固醇和载脂蛋白,并比较计算其辨别力和诊断价值。结果和结论冠心病患者的TC(女)、TG、LDL-C、ApoB、LDL-C/HDL-C和ApoB/ApoAI明显高于正常人(P<0.05),HDL2-C、HDL3-C、HDL-C、ApoAI和HDL-C/TC明显低于正常人(P<0.05)。由HDL-C、TC和TG血脂三项可代替HDL-C、LDL-C、VLDL-C、TC和TG血脂五项,对冠心病的诊断目前有应用价值,若加上HDL2-C和HDL3-C或ApoAI和ApoB,则对冠心病的诊断更有意义。
