Abstract
Herpes zoster (HZ), resulting from the reactivation of the varicella-zoster virus, is a significant disease. This study aimed to explore the factors influencing sensory neuron involvement in HZ at different locations and its association with postherpetic neuralgia (PHN). A total of 3143 cases were retrieved from an electronic medical record system, including 2676 cases of HZ and 467 cases of PHN. Gender, age, site of onset, past surgical history, and comorbidities were analyzed using a multifactorial logistic regression model. The results revealed correlations between age, gender, comorbidities (diabetes, coronary heart disease, percutaneous coronary intervention [PCI]), and sensory neuron involvement in HZ. Specifically, older age, female gender, and comorbid conditions such as diabetes/coronary heart disease were associated with sacral dorsal root ganglion (DRG) involvement, while PCI history was associated with lumbar DRG involvement. Additionally, sensory neuron involvement at different locations by HZ was linked to PHN. Furthermore, independent risk factors for PHN included thoracic DRG involvement, older age, and comorbidities (diabetes, surgical history, malignancy). It is crucial to prevent damage to the DRG, especially in individuals with comorbidities, through activities avoidance and active treatment, to minimize the occurrence of PHN.

J Ren Nutr 2019; 30:223-231. [PMID: 31607549 DOI: 10.1053/j.jrn.2019.08.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2019] [Revised: 08/02/2019] [Accepted: 08/11/2019] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE The aim of this study was to evaluate the interaction between diet quality and interleukin (IL)-6 genotypes and its association with metabolic and renal function parameters in Mexican patients with type 2 diabetes mellitus (T2DM). DESIGN AND METHODS Using an analytical cross-sectional design, 219 patients with T2DM (92 men; age 62 ± 10 years) were evaluated for selected metabolic and renal function parameters. Diet quality according to the Healthy Eating Index was evaluated and classified as good diet or poor diet in all patients. IL-6 serum concentrations and genotypes and haplotypes for IL6-597G > A (rs180097), -572G > C (rs180096), and -174G > C (rs180095) polymorphisms were determined. RESULTS Eighty-two percent of patients reported having a poor diet. Carriers of alleles -572C and -174C showed higher high-density lipoprotein cholesterol levels (44 ± 12 vs. 40 ± 9 mg/dL; P = .01) and lower total cholesterol levels (184 ± 33 vs. 197 ± 42 mg/dL; P = .03) than did those homozygous for G/G. Neither IL6 genotypes nor haplotypes were significantly associated with serum concentrations of IL-6. Some significant interactions between IL6 genotypes/haplotypes and diet quality were associated with body mass index, waist circumference, high-density lipoprotein cholesterol levels, and estimated glomerular filtration rate. CONCLUSIONS Interactions between diet quality and IL6 genotypes/haplotypes were associated with the main metabolic and renal function parameters in Mexican patients with T2DM. It will be important to consider genetic profiles in designing dietary portfolios and nutritional interventions for the management of such patients.

Interleukin-1 Alpha Polymorphisms Are Associated With Body Mass Index in Male But Not in Female Adolescents. Arch Med Res 2019; 50:151-157.

Abstract
BACKGROUND The Interleukin (IL)-1 family of cytokines plays a key role in the inflammatory response. Genes coding for IL-1α, IL-1β, and IL-1Ra are located together as a block gene known as the IL-1 cluster. This genomic region shows wide nucleotide variability, and some polymorphisms have been widely studied and associated with features related to the metabolic syndrome. METHODS Eight polymorphisms within three genes of the IL-1 cluster, including IL1A (rs3783553, rs17561, and rs1800587), IL1B (rs1143634, rs1143627, and rs16944) and IL1RN (rs419598 and rs2234663) were genotyped in 460 Mexican adolescents. Genotype and haplotype frequencies are reported, as well as the linkage disequilibrium analysis. Genetic associations with some anthropometric and metabolic traits were evaluated. RESULTS Allele frequencies were similar to those found in other populations, and genotype proportions were according to the Hardy-Weinberg equilibrium. Seven haplotypes were observed at frequencies ≥5%. Of the entire cluster, only the rs17561-rs1800587 and rs1143627-rs16944 pairs showed highest and significant linkage disequilibrium values. An haplotype of IL1A, rs17561T-rs1800587T, was significantly associated with increase in body mass index in males (p <0.008), whereas IL1B and IL1RN variants showed associations with insulin, and hs-CRP (p <0.05). CONCLUSIONS Some MetS parameters seem to be influenced by variations in the IL-1 gene cluster in Mexican adolescents. These variations may confer risk for metabolic alterations from early ages, and and these risks may be different when variables such as sex are considered. Strategies leading to generate protective behaviors could be designed to take into account specific variations in the IL-1 gene cluster and biological conditions such as sex.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD), the most common chronic liver disease in adolescents, is a feature of metabolic syndrome (MetS). Obesity and insulin resistance (IR) are risk factors for NAFLD, as well as inflammation-related genetic markers. The relationship between metabolic or inflammation-related genetic markers and alanine aminotransferase (ALT) is not fully understood. We examined the relationship of MetS, metabolic and inflammation-related genetic markers with elevated ALT in adolescents. METHODS A total of 674 adolescents participated in a cross-sectional study in Guadalajara, Mexico. Elevated ALT (>40 IU/L), a surrogate marker of NAFLD, and MetS (International Diabetes Federation definition) were evaluated. Obesity, IR, lipids, C-reactive protein (CRP) and genetic markers (TNFA-308G>A, CRP+1444C>T, IL1RN and IL6-597/-572/-174 haplotype) were evaluated. Multivariate logistic regression was performed. RESULTS Elevated ALT was observed in 3% and 14.1% (total and obese, respectively) of the adolescents. Obesity (odds ratio [OR], 5.86; 95% confidence interval [95% CI], 1.16-25.89), insulin (OR, 8.51; 95% CI, 2.61-27.71), IR (OR, 9.10; 95% CI, 2.82-29.38), total cholesterol (TC) (OR, 3.67; 95% CI, 1.25-10.72), low-density lipoprotein-cholesterol (LDL-C) (OR, 3.06; 95% CI, 1.06-8.33), non-high-density lipoprotein-cholesterol (HDL-C) (OR, 3.88; 95% CI, 1.27-11.90) and IL1RN (OR, 4.64; 95% CI, 1.10-19.53) were associated with elevated ALT. Among males, ≥2 MetS criteria were associated with elevated ALT (OR, 4.22; 95% CI, 1.14-15.71). CONCLUSIONS Obesity, insulin, IR, high TC, high LDL-C, high non-HDL-C and IL1RN polymorphism were associated with elevated ALT. Among males, ≥2 MetS criteria were associated with elevated ALT. There is an urgent need to reduce obesity and IR in adolescents to prevent NAFLD.

[PMID: 29257205 PMCID: PMC5780105 DOI: 10.3892/mmr.2017.8067] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2016] [Accepted: 04/07/2017] [Indexed: 01/26/2023] Open
Abstract
The present study aimed to determine the effects of Tianxiangdan Granule on nuclear factor (NF)-κB p65 and p38 mitogen-activated protein kinase (MAPK) inflammatory signaling pathways, and explored the possible mechanism underlying the effects of Tianxiangdan Granule on prevention and treatment of atherosclerosis. A total of 48 apolipoprotein E−/− mice (age, 8 weeks) were selected and divided into two groups: The normal control group (n=12) and the modeling group (n=36). In the modeling group, mice were fed a high-fat diet and were maintained in an artificial climate box, in order to stimulate the climate and eating habit characteristics of Xinjiang. Every morning, ApoE−/− mice in the modeling group were placed in the artificial climate box at 10:00 am and were taken out at 09:00 pm and placed back in the room temperature environment. The temperature of the artificial climate box was set at 6±2°C, relative humidity was controlled at 25–32.8% and the light-dark cycle was 12 h/day. The purpose of this method was to establish the Huizhuo Tanzu type atherosclerosis model. Following successful generation of the model, mice in the modeling group were randomly divided into three groups: Model group (n=10), Tianxiangdan group (n=10) and atorvastatin group (n=10). After 12 weeks, mice were sacrificed and the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α in each group were detected. Furthermore, the expression levels of NF-κB p65 and p38 MAPK in aortic tissue were detected. The results indicated that the concentrations of IL-1β and TNF-α were significantly higher in mice in the model group compared with in the normal control group (P<0.01), whereas the concentrations of IL-1β and TNF-α were lower in the Tianxiangdan and atorvastatin groups compared with in the model group (P<0.01). Furthermore, the protein expression levels of phosphorylated (p)-NF-κB p65 and p-p38 MAPK protein were higher in aortic tissues from the model group compared with in the normal control group (P<0.01), p-NF-κB p65 and p-p38 MAPK protein expression was reduced in the atorvastatin and Tianxiangdan groups compared with in the model group. The present study indicated that the mechanism underlying the effects of Tianxiangdan Granule on the prevention and treatment of atherosclerosis may be as follows: Tianxiangdan Granule may decrease the expression of the inflammatory cytokines IL-1β and TNF-α, and suppress activation of the NF-κB p65 and p38 MAPK signaling pathways.

Abstract
Genome-wide association studies (GWAS) and next generation sequencing studies (NGSS) are often performed in family studies to improve power in identifying genetic variants that are associated with clinical phenotypes. Efficient analysis of genome-wide studies with familial data is challenging due to the difficulty in modeling shared but unmeasured genetic and/or environmental factors that cause dependencies among family members. Existing genetic association testing procedures for family studies largely rely on generalized estimating equations (GEE) or linear mixed-effects (LME) models. These procedures may fail to properly control for type I errors when the imposed model assumptions fail. In this article, we propose the Sequence Robust Association Test (SRAT), a fully rank-based, flexible approach that tests for association between a set of genetic variants and an outcome, while accounting for within-family correlation and adjusting for covariates. Comparing to existing methods, SRAT has the advantages of allowing for unknown correlation structures and weaker assumptions about the outcome distribution. We provide theoretical justifications for SRAT and show that SRAT includes the well-known Wilcoxon rank sum test as a special case. Extensive simulation studies suggest that SRAT provides better protection against type I error rate inflation, and could be much more powerful for settings with skewed outcome distribution than existing methods. For illustration, we also apply SRAT to the familial data from the Framingham Heart Study and Offspring Study to examine the association between an inflammatory marker and a few sets of genetic variants.

Interleukin-1 Gene Cluster Polymorphisms and Their Association with Coronary Artery Disease: Separate Evidences from the Largest Case-Control Study amongst North Indians and an Updated Meta-Analysis. PLoS One 2016; 11:e0153480. [PMID: 27078871 PMCID: PMC4831754 DOI: 10.1371/journal.pone.0153480] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2015] [Accepted: 03/30/2016] [Indexed: 02/06/2023] Open
Abstract
Several researchers have reported significant association of numerous single nucleotide polymorphisms (SNPs) residing in the interleukin-1 (IL-1) gene cluster with coronary artery disease (CAD). However, their association status amongst North Indian ancestry (NIA) have never been systematically assessed. Despite a published meta-analysis on this subject, their association status worldwide as well as amongst different major ancestral subgroups still remains unclear. We therefore decided to prospectively test the association of 11 IL-1 gene cluster SNPs with CAD, vide a case-control study amongst a cohort of NIA and attempted to validate our results with the help of an updated meta-analysis of all relevant published association studies. Included studies were segregated into ancestral subgroups and association statuses for each subgroup were determined. A total of 323 cases and 400 healthy, age and sex matched controls belonging to NIA were prospectively enrolled and subsequently genotyped for 11 selected IL-1 gene cluster SNPs. Although results for none of the evaluated IL-1 gene cluster SNPs reached the adjusted level of significance (p<0.0045), clear trends of association were seen for IL1B -511 C>T and IL1RN 86bp VNTR in several of the constructed genetic models (p range = 0.01–0.044 and 0.005–0.034 respectively). The presence of >1, ‘T’ (minor) allele of IL1B -511 C>T in a genotype seemed to provide protection against CAD (OR = 0.62, p = 0.044), while the presence of >1, ‘C’ (major) allele seemed to increase the risk of CAD (OR = 1.36, p = 0.041). The minor allele (allele 2) of IL1RN 86bp VNTR and its homozygous genotype (2/2 genotype) also seemed to carry an increased risk for CAD (OR = 1.62, p = 0.005 and OR = 2.25, p = 0.031 respectively). On the other hand, several haplotype combinations constructed out of IL1B and IL1RN gene variants clearly showed statistically significant associations with CAD (p<0.0045). Our meta-analysis was conducted for 8 previously assessed IL-1 SNPs. We included 53 different studies which involved a total sample of 26,210 (13,982 cases and 12,228 controls). Our pooled results concurred with the findings of our case-control study and was not able to deduce any statistically significant associations for any of the 8 studied SNPs (p>0.05). Subgroup analysis, however, yielded interesting results, where significant differences in association statuses were seen for IL1A +4845 G>T, IL1B -511 C>T, IL1RN 86bp VNTR and IL1RN +8006 T>C for select ancestral subgroups. The hints of associations deduced for subjects belonging to NIA in our case-control study for both IL1B -511 C>T and IL1RN 86bp VNTR were duly validated vide significant p values seen for NIA in all three genetic models (OR range = 0.62–0.76, p range = 0.01–0.04 and OR range = 1.51–2.25, p range = 0.004–0.04 respectively). On the other hand, Mixed Ancestry (MA) subgroup carrying IL1B -511 C>T, IL1RN 86bp VNTR or IL1RN +8006 T>C polymorphisms seemed to enjoy significant protection against CAD. A few other ancestral subgroups also demonstrated significant associations for a few of the studied SNPs vide one of the three genetic models. Clinical interpretation of derived results is however recommended.

Abstract
Increased body mass index (BMI) has been linked to various detrimental health outcomes, including cognitive dysfunction. Recent work investigating associations between obesity and the brain has revealed decreased white matter microstructural integrity in individuals with elevated BMI, independent of age or comorbid health conditions. However, the relationship between high BMI and white matter fiber bundle length (FBL), which represents a novel metric of microstructural brain integrity, remains unknown. The present study utilized quantitative tractography based on diffusion tensor imaging (DTI) to investigate the relationship between BMI and FBL in 72 otherwise healthy older adults (24 males, 48 females). All participants were between 51 and 85 years of age (M = 63.26, SD = 8.76). Results revealed that elevated BMI was associated with shorter FBL in the temporal lobe, independent of age (p < .01). In addition, increased age was associated with shorter frontal, temporal, and whole brain FBL (all p values < .01). These findings indicate that, while increased age is an important factor associated with reduced FBL, high BMI is uniquely associated with reduced FBL in the temporal lobe. These data offer evidence for additive adverse effects of high BMI on the brain, especially in areas already vulnerable to aging processes and age-related neurodegenerative diseases. Further research is necessary to determine the physiological mechanisms associated with the shortening of FBL in individuals with high BMI.

Low prevalence of interleukin-6 haplotypes associated with a decreased risk of type 2 diabetes in Mexican subjects with a family history of type 2 diabetes. Arch Med Res 2013; 44:529-34. [PMID: 24051035 DOI: 10.1016/j.arcmed.2013.09.003] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2013] [Accepted: 08/26/2013] [Indexed: 01/02/2023]
Abstract
BACKGROUND AND AIMS There is evidence that family history of type 2 diabetes (FHT2D) and single nucleotide polymorphisms (SNP) on the IL-6 gene promoter region are separately associated with the risk of developing type 2 diabetes. However the relationship between adult Mexican subjects with FHT2D and genotypes/haplotypes for IL-6 gene has not been explored. The aim of the present work was to study the prevalence of IL-6 -598G>A-572G>C-174G>C haplotypes among subjects with FHT2D and to determine whether their presence influences the relationship between FHT2D and risk factors for diabetes. METHODS Two hundred fifty eight nondiabetic subjects participated in this study; 153 with and 105 without FHT2D. Polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) was used for genotyping. Logistic regression analysis was employed to assess the impact of IL-6 haplotypes on FHT2D per se and hyperinsulinemia and insulin resistance as risk factors for diabetes. RESULTS Subjects with FHT2D showed a higher prevalence of hyperinsulinemia and insulin resistance (IR) than those without FHT2D (14.4 vs. 5.7%, p = 0.029, and 14.2 vs. 7.0% p = 0.050, respectively). Lower prevalence of -598 -572-174 (AGC)-haplotype (19%) in subjects with FHT2D was observed as well as a lower prevalence of hyperinsulinemia and IR among AGC haplotype carriers (12 and 14%, respectively). The relationship between FHT2D and IR was modified by the presence of AGC haplotype (from OR, 2.70; 95% CI, 0.99-7.36; p = 0.050 OR, 30.08; 95% CI, 0.58-1,568.06; p = 0.092). CONCLUSIONS IL-6 -598/-572/-174 (AGC) haplotype has a low prevalence among first-degree relatives of subjects with type 2 diabetes. Our results suggest that this haplotype is associated with decreased risk of type 2 diabetes in Mexican subjects with FHT2D.

Abstract
BACKGROUND Altered immune responses are seen in depression, and recent data suggest that similar changes could also be observable in alexithymia. We examined whether the inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and interleukin (IL)-6 are independently related to alexithymia or its factors in a population-based sample. METHODS This study formed a clinical part of the Kuopio Depression (KUDEP) general population study focusing on the mental health of a general population of adults aged 25-64 years (n = 308). Alexithymia was measured using the Toronto Alexithymia Scale (TAS-20), and depressive symptoms were assessed using the Beck Depression Inventory (BDI-21). RESULTS The levels of IL-6 (in picograms per milliliter) and hs-CRP (in milligrams per liter) were significantly higher in alexithymic than in nonalexithymic subjects (IL-6 effect size, ES: 0.50; hs-CRP ES: 0.27). The BDI scores, hs-CRP and IL-6 explained 33.5% of the variation in TAS scores in the whole study population. According to logistic regression analysis, hs-CRP but not IL-6 increased the likelihood of belonging to the alexithymic group. This observation remained unaltered after additional adjustments for chronic inflammation-related disorders, the use of inflammation-modulating medications and depressive symptoms. CONCLUSIONS Our findings suggest that the association between hs-CRP and alexithymia resembles that observed in depressed patients. It is, however, independent of depressive symptoms. These findings widen our view on the stress-alexithymia concept.

Abstract
Obesity is currently considered a serious public health issue due to its strong impact on health, economy, and quality of life. It is considered a chronic low-grade inflammation state and is directly involved in the genesis of metabolic disturbances, such as insulin resistance and dyslipidemia, which are well-known risk factors for cardiovascular disease. Furthermore, there is evidence that genetic variation that predisposes to inflammation and metabolic disturbances could interact with environmental factors, such as diet, modulating individual susceptibility to developing these conditions. This paper aims to review the possible interactions between diet and single-nucleotide polymorphisms (SNPs) in genes implicated on the inflammatory response, lipoprotein metabolism, and oxidative status. Therefore, the impact of genetic variants of the peroxisome proliferator-activated receptor-(PPAR-)gamma, tumor necrosis factor-(TNF-)alpha, interleukin (IL)-1, IL-6, apolipoprotein (Apo) A1, Apo A2, Apo A5, Apo E, glutathione peroxidases 1, 2, and 4, and selenoprotein P exposed to variations on diet composition is described.

Abstract
BACKGROUND Markers of inflammation and fibrin turnover are elevated in individuals with a large (>55 mm) abdominal aortic aneurysm (AAA). Fibrin degradation generates D-dimer, known to possess multiple proinflammatory effects, and levels are elevated during early AAA development. This study characterized the plasma inflammatory response during early AAA pathogenesis to determine the effect of D-dimer levels. METHODS The study compared 75 men with a small AAA (range, 30-54 mm) with 90 age-, sex-, and race-matched controls. Plasma interleukin-6 (IL-6), complement C3, high-sensitivity C-reactive protein (hsCRP), fibrinogen, and D-dimer levels were measured. RESULTS Mean levels of fibrinogen (2.92 vs 2.59 g/L; P = .003), hsCRP (2.07 vs 1.29 ng/mL; P = .005), and D-dimer (346.7 vs 120.2 ng/mL; P < .001) were higher in men with a small AAA. These markers correlated with maximum aortic diameter determined by ultrasound imaging. On multivariate analysis, D-dimer levels were elevated in AAA individuals independent of smoking, cardiovascular disease (CVD), atherosclerotic risk factors, and inflammatory parameters. Fibrinogen and hsCRP levels remained elevated after adjustment for these covariates but lost significance when D-dimer was added to the model. CONCLUSION C-reactive protein and D-dimer levels are elevated during early AAA development. D-dimer levels are most tightly associated with AAA status, however, and may mediate the observed elevation in acute-phase reactants.

Abstract
We aimed to evaluate the relationship between 174 promoter region of the interleukin-6 (IL-6) C/G gene polymorphism and high sensitive C-reactive protein (hs-CRP), fibrinogen and carotis intima-media thickness (CIMT), body mass index, homeostatic model assessment (HOMA) insulin resistance index, serum lipid parameters, in polycystic ovary syndrome (PCOS) patients carrying a potential risk for developing cardiovascular disease (CVD). We studied 88 PCOS patients and 119 healthy controls. PCOS was defined by the Rotterdam PCOS consensus criteria. The genotype IL-6 distribution did differ between the control group (CC 10.1%, GC 63.0%, GG 29.6%) and the PCOS patients (CC 5.7%, GC 29.5%, GG 64.8%) (P < 0.001). The frequency of the polymorphic G allele was also no similar for the group with PCOS as for the control group with 79.5% and 58.4% respectively (P < 0.001). Both in PCOS patients and in control group, no statistically significant difference was determined between C/C, G/C and G/G, and blood cholesterol levels, triglyceride levels, high-density lipoprotein levels, low density lipoprotein levels, fasting blood sugar levels, insulin levels, HOMA values, CIMT measurements either on the right or left side, hs-CRP, f-testosterone, fibrinogen and 17 alpha-hydroxy-progesterone levels (P > 0.05). Gene polymorphism of IL-6 -174 G>C is a risk factor for PCOS in Turkish patients, but we found no relationship between the cardiovascular risk factors and IL-6 -174 G>C gene polymorphism in women with PCOS and healthy subjects. Our negative results in risk factors of CVD can probably be explained by the fact that metabolic parameters and endothelial systems of patients may not yet be affected in this short time of period.

Abstract
It now appears that obesity is associated with a low-grade inflammation of white adipose tissue resulting from chronic activation of the innate immune system as interleukin-1 beta (IL-1). Previous investigations have described a positive association between IL-1 beta +3953 (C>T) gene polymorphism (rs 1143634) and obesity, suggesting functional effects on fat mass, fat metabolism and body mass. However, it is necessary to determine if these results occur in other populations and if they are influenced by sex and age. Therefore, we performed a case-control study using 880 Caucasian subjects (59.7+/-11.9 years old) from the Brazilian Aging Research Program (non-overweight=283, overweight=334, obese=263) previously investigated in genetic studies, in whom we analyzed the IL-1 beta +3953C/T polymorphism. We observed higher T allele (CT/TT) frequency in non-overweight than overweight and obese groups. The odds ratio showed 1.340 (95% CI: 1.119-1.605) times more chance of the obese group being CC carriers compared to non-overweight group independent of sex and age. This study corroborates the idea that the IL-1 system is linked to the development of obesity.

Abstract
Low-grade inflammation, a minor elevation in the baseline concentration of inflammatory markers such as C-reactive protein (CRP), is nowadays recognized as an important underlying condition in many common diseases. Concentrations of CRP under 10 mg/1 are called low-grade inflammation and values above that are considered as clinically significant inflammatory states. Epidemiological studies have revealed demographic and socioeconomic factors that associate with CRP concentration; these include age, sex, birth weight, ethnicity, socioeconomic status, body mass index (BMI), fiber consumption, alcohol intake, and dietary fatty acids. At the molecular level, production of CRP is induced by proinflammatory cytokines IL-1, IL-6, and IL-17 in the liver, although extra hepatic production most likely contributes to systemic concentrations. The cytokines are produced in response to, for example, steroid hormones, thrombin, C5a, bradykinin, other cytokines, UV-light, neuropeptides and bacterial components, such as lipopolysaccharide. Cytokines exert their biological effects on CRP by signaling through their receptors on hepatic cells and activating different kinases and phosphatases leading to translocation of various transcription factors on CRP gene promoter and production of CRP protein. Genetic polymorphisms in the interleukin genes as well as in CRP gene have been associated with minor elevation in CRP. As minor elevation in CRP is associated with both inflammatory and noninflammatory conditions, it should be noticed that the elevation might just reflect distressed or injured cells homeostasis maintenance in everyday life, rather than inflammation with classical symptoms of redness, swelling, heat, and pain.

Abstract
This study investigated risk factors for atherosclerosis and their relationship with lesion sites. Patients (n = 160) with peripheral artery disease (PAD) completed a questionnaire regarding risk factors for PAD. Endothelial nitric oxide synthase (eNOS) and interleukin (IL)-6 gene polymorphisms and asymmetric dimethylarginine (ADMA) levels were measured. Patients with coronary artery disease had significantly higher ratios of eNOS T/C and C/C genotypes, which include the C allele, than the T/T genotype. The IL-6 gene polymorphism distribution ratios for patients with over four risk factors were significantly different compared with other patients, with a higher rate of the C/C genotype. ADMA levels did not show any significant relationship to risk factors or polymorphism. Levels were, however, slightly higher in femoral lesion sites. The results support a model in which the C/C genotype of eNOS and IL-6 gene polymorphisms promote PAD development. The eNOS C/C genotype may have an independent effect, whereas the effects of the IL-6 C/C genotype are seen in conjunction with other risk factors.

Abstract
The aim of our work was to find if MCP-1 -2518 (A/G) single nucleotide polymorphism (SNP) influences somehow the serum concentrations of high-sensitive CRP (hsCRP) both in patients suffering from ischemic heart disease (IHD), myocardial infarction (MI), angina pectoris (AP), and hypertension (HT) and in control group of healthy subjects. Totally, 263 patients with the diagnosis of IHD, out of them 89 with MI, 145 with AP, 205 with HT, and also 67 healthy subjects were included in the study. First, we estimated the serum levels of hsCRP. We found that patients with AP had significantly higher serum level of hsCRP than both control group of healthy subjects (P = .043) and IHD patients without AP (P = .026). The presence of the mutant G allele statistically significantly correlated with the higher serum levels of hsCRP in patients with IHD (P = .016), AP (P = .004), and HT (P = .013). Higher correlations were found in men (AP: P = .019; HT: P = .047). In all cases the highest levels of hsCRP were found both in patients and healthy controls with homozygous GG genotype.

Abstract
BACKGROUND AND OBJECTIVE Although an elevation in the concentration of high-sensitivity C-reactive protein (hs-CRP) as a result of periodontal infection may account for an increased risk of developing coronary heart disease (CHD), the effect of periodontal infection on the level of hs-CRP in an otherwise healthy Japanese population has not yet been reported. The aim of the present study was to confirm, on a larger scale, our previous pilot study findings that both chronic periodontitis and subsequent periodontal treatment alter the serum levels of C-reactive protein (CRP), interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-alpha). MATERIAL AND METHODS The concentrations of serum hs-CRP, IL-6 and TNF-alpha were measured in 78 periodontitis patients at baseline and at re-assessment, and in 40 periodontally healthy subjects at the time of examination. RESULTS The concentrations of hs-CRP and IL-6 in the sera of periodontitis patients were significantly higher than those in control subjects. By contrast, the concentration of TNF-alpha was significantly lower in periodontitis patients than in control subjects. Whereas periodontal treatment decreased the levels of serum hs-CRP and IL-6, no such effect was observed for TNF-alpha. When the patients were subdivided into four groups according to their initial concentration of hs-CRP, only the CRP and IL-6 concentrations of the highest quartile group showed a significant reduction following periodontal treatment. No significant difference in the initial clinical parameters was observed in any quartile. CONCLUSION Although periodontal infection does affect the concentration of hs-CRP and IL-6 in serum, a subgroup of patients exist who are highly susceptible to an increased risk of CHD associated with periodontitis, suggesting that there may be subjects who have an elevated risk of CHD independent of susceptibility to periodontal tissue destruction per se.

Inflammation as a cardiovascular risk factor and pulse wave velocity as a marker of early-stage atherosclerosis in the Japanese population. Environ Health Prev Med 2009; 14:159-64. [PMID: 19568843 DOI: 10.1007/s12199-009-0080-2] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2008] [Accepted: 02/13/2009] [Indexed: 10/21/2022] Open
Abstract
Inflammation and pulse wave velocity (PWV) are a potential risk factor and marker, respectively, for atherosclerosis in the primary prevention setting. Atherosclerosis is now generally accepted to be an inflammatory disorder of the arterial wall, and the high-sensitivity C-reactive protein (hs-CRP) level has been reported to be a strong predictor of cardiovascular events. High-sensitivity-CRP is associated with two factors related to inflammation: (1) the local production of CRP by atheromatous tissue or coronary artery smooth muscle cells and (2) adipose tissue as a potent source of inflammatory cytokines. Based on studies in North America and Europe, hs-CRP has been established as a cardiovascular risk factor and a cut-off value has been recommended. However, Japanese have lower hs-CRP values than their Western counterparts, partly because Japanese have a lower body mass index (BMI), which correlates positively to hs-CRP, and partly because lifestyle and genetic factors can affect hs-CRP values. Therefore, a cut-off value needs to be established by cohort studies for the Japanese population. Carotid-femoral PWV is most commonly measured by applanation tonometry, particularly in Europe, but this method is critically dependent upon the accurate placing of transducers over the arteries and is both time-consuming and complex. A novel device has been recently developed in Japan that measures brachial-ankle PWV (baPWV) using a volume-rendering method. Brachian-ankle PWV is a suitable screening method because of its technical simplicity and shorter measurement time. It is associated not only with conventional cardiovascular risk factors but also with new risk factors, such as inflammation, gamma-glutamyltransferase, chronic kidney disease, and psychosocial factors. However, a suitable cut-off value has yet to be established.

Abstract
OBJECTIVE Abundant evidence supports the central role of inflammatory cytokines in immune responses mediating the pathogenesis of atherosclerosis, coronary artery disease, and its complications, such as myocardial infarction and unstable angina. METHODS We investigated the association of genetic polymorphisms of the inflammatory cytokines, IL-10, TGF-beta1, IFN-gamma, IL-6, and TNF-alpha with the clinical presentation of coronary artery disease in 26 patients with stable angina, 45 patients with unstable angina and 58 patients who had experienced nonfatal myocardial infarction. Genotyping was performed by the sequence-specific primer polymerase chain reaction method. RESULTS A significant difference in the frequencies of -174G/C IL-6 alleles was observed, with the low in-vitro producing -174*C allele predominating in patients with myocardial infarction, compared with stable angina and unstable angina patients, after the analysis of genotypes (P=0.024 and 0.022, respectively), phenotypes [P=0.0099, odds ratio (OR)=0.271, 95% confidence interval (CI)=0.1012-0.7292; P=0.03, OR=0.40, respectively] and haplotypes (P=0.007, OR=3.028, 95% CI=1.347-6.806; P=0.0096, OR=2.368, 95% CI=1.262-4.444; respectively). In addition, a predominance of the -1082ACC/ATA IL-10 genotype in the myocardial infarction group compared with the unstable angina group and the -874 A/A IFN-gamma genotype in the stable angina group compared with the unstable angina and the myocardial infarction group, was found. No significant differences in the distribution of genotypes, phenotypes and haplotypes in the three study groups, for the TNF-alpha-308 A/G and TGF-beta1-codon 25 G/C, codon 10 T/C polymorphisms were detected. CONCLUSION Our data provide evidence that the IL-6-174G/C polymorphism may be involved in the pathogenesis of coronary artery disease, contributing to genetic susceptibility for myocardial infarction.

Abstract
BACKGROUND Polymorphisms in the proinflammatory cytokine interleukin (IL)-1beta gene have been associated with systemic atherogenesis, thrombosis and rupture. The aim of this study was to investigate associations between single nucleotide polymorphisms (SNPs) in IL-1beta and intracranial hemorrhage (ICH) in the natural course of brain arteriovenous malformation (BAVM) patients. METHOD Two IL-1beta promoter SNPs (-511C-->T, -31T-->C) and 1 synonymous coding SNP in exon 5 at +3953C-->T (Phe) were genotyped in 410 BAVM patients. We performed a survival analysis of time to subsequent ICH, censoring cases at first treatment, death or last follow-up. A Cox regression analysis was performed to obtain hazard ratios (HRs) for genotypes adjusted for age, sex, Caucasian race/ethnicity and hemorrhagic presentation. RESULTS Subjects with the -31 CC genotype (HR = 2.7; 95% CI 1.1-6.6; p = 0.029) or the -511 TT genotype (HR = 2.6; 95% CI 1.1-6.5; p = 0.039) had a greater risk of subsequent ICH compared with reference genotypes, adjusting for covariates. The +3953C-->T SNP was not significantly associated with an increased ICH risk (p = 0.22). The IL-1beta promoter polymorphisms were also associated with BAVM susceptibility among a subset of 235 BAVM cases and 255 healthy controls of Caucasian race/ethnicity (p < 0.001). CONCLUSION IL-1beta promoter polymorphisms were associated with an increased risk of ICH in BAVM clinical course and with BAVM susceptibility. These results suggest that inflammatory pathways, including the IL-1beta cytokine, may play an important role in ICH.

Abstract
Maternal plasma CRP concentrations in pregnancy are increased over pre-pregnancy values and high concentrations have been associated with adverse obstetrical outcomes. The objective of this study was to explore the relationship between maternal and fetal variation in C-reactive protein (CRP) genotype and maternal plasma CRP concentrations in the first trimester in low risk patients. DNA was extracted from maternal and cord blood of subjects in a prospective observational cohort. Single-nucleotide polymorphism (SNP) selection was made using a linkage disequilibrium bin approach. CRP concentrations were measured in first trimester maternal plasma using an enzyme-linked immunosorbent assay (ELISA) kit. Kruskal-Wallis rank testing was used to analyze genetic and clinical determinants of CRP concentrations. Genotype results were available in 190 mother-baby pairs. There was no significant difference in CRP concentration among maternal or fetal CRP genotypes. Thus, first trimester concentrations of maternal plasma CRP in low risk subjects do not appear to be significantly associated with CRP genotype. Instead, differences in clinical factors probably have more influence on baseline maternal CRP concentrations.

Abstract
BACKGROUND Circulating levels of acute phase reactant proteins such as plasma C-reactive protein (CRP) are likely influenced by multiple genes regulating the innate immune response. METHODS AND RESULTS We screened a set of 16 inflammation-related genes for association with CRP in a large population-based study of healthy young adults (n=1627). Results were validated in 2 independent studies (n=1208 and n=4310), including a pooled analysis of all 3 studies. In the pooled analysis, the minor allele of IL1RN 1018 (rs4251961) within the gene encoding interleukin (IL)-1 receptor antagonist (IL-1RA) was significantly associated with higher mean plasma log(CRP) level (P<1 x 10(-4)). The same IL1RN 1018 allele was associated with higher mean plasma log(IL-6) levels (P=0.004). In the pooled analysis, the minor allele of IL1RN 13888 (rs2232354) was associated with higher fibrinogen, (P=0.001). The IL1RN 1018 and 13888 variant alleles tag a clade of IL1RN haplotypes linked to allele 1 of an 86-bp VNTR polymorphism. We confirmed that the IL1RN 1018 variant (rs4251961) was associated with decreased cellular IL-1RA production ex vivo. CONCLUSIONS Common functional polymorphisms of the IL1RN gene are associated with several markers of systemic inflammation.

Abstract
Basal levels of C-reactive protein (CRP) have been associated with disease, particularly future cardiovascular events. Twin studies estimate 50% CRP heritability, so the identification of genetic variants influencing CRP expression is important. Existing studies in populations of European ancestry have identified numerous cis-acting variants but leave significant ambiguity over the identity of the key functional polymorphisms. We addressed this issue by typing a dense map of CRP single-nucleotide polymorphisms (SNPs), and quantifying serum CRP in 594 unrelated African Americans. We used Bayesian model choice analysis to select the combination of SNPs best explaining basal CRP and found strong support for triallelic rs3091244 alone, with the T allele acting in an additive manner (Bayes factor > 100 vs. null model), with additional support for a model incorporating both rs3091244 and rs12728740. Admixture analysis suggested SNP rs12728740 segregated with haplotypes predicted to be of recent European origin. Using a cladistic approach we confirmed the importance of rs3091244(T) by demonstrating a significant partition of haplotype effect based on the rs3091244(C/T) mutation (F = 8.91, P = 0.006). We argue that weaker linkage disequilibrium across the African American CRP locus compared with Europeans has allowed us to establish an unambiguous functional role for rs3091244(T), while also recognising the potential for additional functional mutations present in the European genome.

Abstract
OBJECTIVE Interleukin-1B (IL1B) modulates C-reactive protein (CRP) expression. However, whether IL1B genetic variation is associated with CRP level is unknown. Further, obesity, a state of low-grade inflammation that influences cellular IL-1 functions may modify this association. METHODS AND RESULTS Study participants (N=3289), 48% blacks and 52% whites, had CRP level measurements at year 7 and year 15 examinations as part of the CARDIA study. Ten tag single nucleotide polymorphisms (SNPs) that characterize common IL1B gene variation were genotyped. In SNP analysis, no significant associations with either level or change in time CRP were observed after multiple testing adjustments. However, global ILIB gene variation was associated with year 7 to year 15 change in CRP (global nominal p=0.004, multiple testing corrected p=0.048) among obese blacks. Compared to the commonest haplotype, a common haplotype that includes the SNP rs1143642 was associated with greater increases in CRP from year 7 to year 15 among obese blacks and whites while another common haplotype that includes the SNP rs3917356 was associated with decreased change in CRP from year 7 to year 15 among obese blacks. The rare alleles of ILIB SNPs, SNP 7114 (rs1143642) and SNP 3298 (rs3917356), were associated with greater increases and decreases in CRP from year 7 to year 15 among blacks, respectively, compared to their common variants. CONCLUSION IL1B genetic variation may have a role in CRP level regulation and this association may be modified by obesity.

Abstract
The lung is a site for repeated or chronic inflammatory insults. Epidemiologic research has provided evidence to support the hypothesis that tissue damage caused by inflammation can initiate or promote the development of lung cancer, possibly in conjunction with tobacco use. For example, some studies suggest an increased risk of lung cancer among persons with lung infections, such as tuberculosis, bacterial pneumonia, or inflammatory lung diseases. Elevated serum levels of C-reactive protein, an inflammation marker, are associated with heightened lung cancer risk. Recent studies also demonstrate increased lung cancer risk among immunosuppressed individuals infected with HIV. Other research indicates an association between genetic polymorphisms in the inflammation pathway, which might modulate the inflammatory response and lung cancer risk.

Abstract
C-reactive protein (CRP) is a heritable acute-phase plasma protein also expressed at low, basal, levels in healthy individuals. Elevated basal CRP has been associated with increased cardiovascular risk, while CRP dysregulation may be a feature of systemic lupus erythematosus (SLE). In this cohort of 496 Caucasian SLE families we estimated basal CRP heritability, h(2)= 27.7%. We typed a dense map of CRP single nucleotide polymorphisms (SNPs) and found that seven were associated with basal CRP using both a regression approach and an orthogonal family-based test (P = 0.001-0.011), as were haplotypes carrying the minor allele of these SNPs. SNPs in the interleukin-1beta and interleukin-6 genes were associated with basal CRP. No association was seen between CRP genotype and SLE. Using a variance components approach we estimated that the CRP genotype accounted for only 15% of the total genetic component of basal CRP variation, perhaps explaining the limited evidence of association between CRP and disease. Most of the genetic determinants of basal CRP variation therefore remain unknown. Multiple genes may be involved and identifying them will provide an insight into pathways regulating CRP expression, highlight potential cardiovascular disease and SLE candidates and improve the ability of basal CRP to predict cardiovascular risk.

Abstract
Basal C-reactive protein (CRP) is a heritable trait associated with long-term cardiovascular disease risk. Existing studies leave ambiguity over the key functional polymorphisms and fail to adjust for trans-acting effects. In a novel cohort of 285 Filipino systemic lupus erythematosus probands and their first-degree relatives, we quantified serum CRP and typed a dense map of CRP single-nucleotide polymorphisms (SNPs), along with SNPs in the interleukin-1 beta, interleukin-6 and apolipoprotein E genes. Ten CRP SNPs demonstrated association with basal CRP in a regression model (P=0.011-0.002). These delineated two haplotypes associated with high and low basal CRP expression (P=0.002). Differences in allele frequency were seen compared with Caucasian populations, enabling us to argue for an independent genetic effect from a phylogenetically distinct haplotype tagged by SNP rs1800947. We demonstrated an association between Apo epsilon 2 and higher basal CRP. Interleukin-6 genotype was associated with basal CRP, highlighting a role for acute-phase cytokines even in basal expression. Identifying these trans-acting variants may improve the use of basal CRP as a predictor cardiovascular risk, and increase our power to detect associations between CRP and disease.

The interleukin 1B-511 polymorphism is associated with the risk of developing restenosis after coronary stenting in Mexican patients. Hum Immunol 2008; 69:116-21. [PMID: 18361937 DOI: 10.1016/j.humimm.2007.12.003] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2007] [Revised: 11/29/2007] [Accepted: 12/17/2007] [Indexed: 12/13/2022]
Abstract
Inflammation is the primary response to vessel wall injury caused by stent placement in coronary arteries. Cytokines of the interleukin-1 family are central regulators in immunoinflammatory mechanisms. The objective of this study was to test for association between IL-1 family gene polymorphisms and risk for restenosis after coronary stent placement. The IL-1B-511, IL-1F10.3, RN.4T>C, RN.6/1C>T, RN.6/2C>G, and IL-1RN VNTR polymorphisms were analyzed by 5' exonuclease TaqMan genotyping assays and polymerase chain reaction in a group of 165 patients who underwent coronary artery stenting. Basal and procedure coronary angiography were analyzed in search of angiographic predictors of restenosis and follow-up angiography was analyzed in search of binary restenosis. Patients with IL-1B-511 TT genotype had a 1.89-fold increased risk of developing restenosis. The analysis considering the lesions treated demonstrated that the lesions of patients with IL-1B-511 TT genotype had a 3.44-fold increased risk of developing restenosis. When the analysis considered the type of stent, the risk of developing restenosis was increased in lesions of patients with TT genotype (odds ratio = 4.50) who underwent coronary bare-metal stent implantation. Multiple logistic analysis identified IL-1B-511 TT genotype as an independent predictor for restenosis. The results suggest that IL-1B-511 polymorphism could be involved in the risk of developing restenosis after coronary stent placement.

Abstract
An emerging goal of medical nutrition therapy is to tailor dietary advice to an individual's genetic profile. In the United States and elsewhere, "nutrigenetic" services are available over the Internet without the direct involvement of a health care professional. Among the genetic variants most commonly assessed by these companies are those found in genes that influence cardiovascular disease risk. However, the interpretation of DNA-based data is complex. The goal of this paper is to carefully examine nutritional genomics as a potential tool for targeted medical nutrition therapy. The approach is to use heart health susceptibility genes and their common genetic variants as the model.
