Abstract
Introduction: Obstructive sleep apnea (OSA) syndrome is a widespread multifactorial disorder that raises the risk of cardiovascular disease, diabetes, and Alzheimer's disease. This study aimed to investigate the association between the risk of OSA and two C-reactive protein (CRP) gene variants, rs1130864 and rs2794521. Materials and methods: In this study, 100 patients and 100 controls participated. Among 500 patients with OSA attending the sleep disorder center, 100 were randomly selected from those with apnea/hypopnea symptoms and daytime sleepiness. Polymerase chain reaction and restriction fragment length polymorphism of the CRP gene polymorphisms were used in this investigation. Results: The frequency of the mutant C allele was higher in the patient group than in the control group for the rs2794521 CRP gene variant (p ≤ 0.001), and the C allele elevated the risk of OSA by 2.584 times (odds ratios = 2.584, 95% confidence interval). The frequency of the mutant T allele was higher in the patient group than in the control group for the rs1130864 CRP gene variant, while the frequency of the C allele was higher in the control group, and this difference was statistically significant (p ≤ 0.001). Conclusions: Our findings indicated that rs1130864 and rs2794521 of the CRP gene are associated with increased risk for OSA. Extensive research is required to determine the role of distinct CRP gene variants in OSA.

TERAPEVT ARKH 2022; 94:491-496. [DOI: 10.26442/00403660.2022.04.201460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 05/25/2022] [Indexed: 11/22/2022]
Abstract
Background. Bacterial pneumonia is a frequent complication of ischemic stroke at the hospital stage. The search for prognostic laboratory markers of pneumonia remains an urgent task, as it will allow to individualize the approach to the treatment and rehabilitation of such patients.
Aim. To investigate the prognostic significance of proteins of the acute phase of inflammation, as well as to evaluate them as early predictors of the development of pneumonia in patients with ischemic stroke.
Materials and methods. The study included 302 patients in the acute period of ischemic stroke. C-reactive protein (CRP), tumor necrosis factor , interleukin-6 (IL-6), neutrophil elastase, neopterin, serum amyloid A (SAA), secreted phospholipase type 2 (sPLA2) were determined in all patients on the first day by enzyme immunoassay. Statistical data processing was carried out using SPSS and Microsoft Excel software (USA).
Results. At the hospital stage, pneumonia developed in 82/302 patients (27.2%; 95% confidence interval 22.332.3%). The levels of CRP, IL-6, sPLA2, SAA and neopterin significantly differed in the presence and absence of pneumonia. Step-by-step logistic regression analysis revealed the significance of IL-6 and CRP concentrations in the prognosis of pneumonia. The threshold value of IL-6 concentration was 3.45 pg/ml (sensitivity 82.4%, specificity 66.7%). The prognostic value of a positive result (PPR) in the prognosis of pneumonia was 40%, a negative result (PNR) 92%. The threshold value of CRP was 1640 mg/l with a sensitivity of 65.8% and a specificity of 74.8%. The PPR of the threshold value of the concentration of CRP was 45%, PNR 80%.
Conclusion. The measurement of the concentration of IL-6 and CRP on the first day of ischemic stroke makes it possible to identify patients with the greatest risk of pneumonia at the hospital stage. The results of the work indicate the necessity to include CRP and IL-6 in the list of mandatory laboratory tests that should be carried out for each patient with ischemic stroke on the first day from the onset of the disease.

BMC Cardiovasc Disord 2022; 22:170. [PMID: 35428187 PMCID: PMC9013148 DOI: 10.1186/s12872-022-02610-z] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2021] [Accepted: 04/01/2022] [Indexed: 11/12/2022] Open
Abstract
Background The C-reactive protein (CRP) is an important biomarker for atherosclerosis and single nucleotide polymorphisms (SNPs) in the CRP locus have been associated with altered CRP levels and associated with risk for cardiovascular disease. However, the association between genetic variations in the CRP gene, estrogen use and CRP levels or early signs of atherosclerosis in young healthy individuals is not fully characterized. We aimed to evaluate the influence of five genetic variants on both plasma CRP levels and carotid intima-media thickness (cIMT) values, including aspects on estrogen containing contraceptive use in females. Methods Genotyping was performed with TaqMan real time PCR and compared with high sensitivity CRP serum levels in 780 Swedish young, self-reported healthy individuals. Haplotypes of the SNPs were estimated with the PHASE v 2.1. The cIMT was measured by 12 MHz ultrasound. The contraceptive use was self-reported. Results Strong associations between CRP and genotype were observed for rs3091244, rs1800947, rs1130864, and rs1205 in women (all p < 0.001). In men, only rs1800947 was associated with CRP (p = 0.029). The independent effect of genotypes on CRP remained significant also after adjustment for established risk factors. Female carriers of the H1/ATGTG haplotype had higher CRP than non-carriers. This was specifically pronounced in the estrogen-using group (p < 0.001), and they had also higher cIMT (p = 0.002) than non-carriers but with a small cIMT difference between the haplotype groups (0.02 mm). In parallel, a significant correlation between CRP and cIMT in the estrogen using group was observed (r = 0.194; p = 0.026). Conclusions Estrogen use, genotypes and haplotypes in the CRP locus are significantly associated with CRP levels. Based on an observed interaction effect between sex/estrogen use and the H1/ATGTG haplotype on CRP, and a marginally thicker cIMT in the estrogen using group, our data suggest that both genotypes and estrogen usage could be involved in arterial wall structural differences. The causality between CRP levels and cIMT remains unclear, and the observed difference in cIMT is not clinically relevant in the present state. Future larger and longitudinal studies may shed further light on the role of more long-term estrogen use and early atherosclerosis.

Abstract
Background: C-reactive protein (CRP) is involved in inflammatory pathways that are associated with the onset and progression of type 2 diabetes mellitus (T2DM) as well as an increased risk of an acute coronary syndrome (ACS). This research aimed to evaluate the potential association of the genetic variants -717T>C, 1444G>A, and 1846 C > T of CRP gene on CRP levels, ACS, and T2DM in participants from Western Mexico. Methods: Six hundred three participants were studied: (1) control group (CG); (2) ACS participants classified as unstable angina (UA), myocardial infarction without ST-segment elevation (NSTEMI), and myocardial infarction with ST-segment elevation (STEMI); (3) T2DM Participants; and (4) ACS plus T2DM participants (ACS+T2DM). Genetic variants were genotyped using allelic discrimination with TaqMan® probes, and high-sensitivity CRP (hs-CRP) was measured by Turbidimetry. Results: TAC haplotype frequency was significantly higher in ACS+T2DM versus CG and versus ACS participants (odds ratio [OR] = 2.774, P = 0.017 and OR = 3.479, P = 0.020, respectively). hs-CRP levels were especially higher for ACS and for ACS+T2DM participants with respect to CG and T2DM (with P < 0.0001). We observed higher hs-CRP levels in NSTEMI and STEMI versus UA in ACS scenario (P = 0.001, P = 0.027, respectively) and for ACS+T2DM scenario (P = 0.0001, P = 0.002, respectively). Conclusion: hs-CRP level fluctuations are related to the presence of T2DM and the presence and severity of ACS. Very high levels (>10 mg/L) are a risk marker of cardiovascular complications. Our results demonstrate a possible relationship between TAC haplotype and an increased risk for T2DM and ACS.

Gene 2020; 753:144808. [PMID: 32470505 DOI: 10.1016/j.gene.2020.144808] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 02/28/2020] [Accepted: 05/22/2020] [Indexed: 12/12/2022]
Abstract
OBJECTIVE C-reactive protein (CRP) is increased in Parkinson's disease (PD). The CRP +1444C/T (rs1130864) polymorphism is located in the 3' untranslated region (3'-UTR) and is associated with serum CRP concentrations. We explored the relationship between the CRP +1444C/T polymorphism and susceptibility to PD. METHODS A total of 1000 subjects from a Chinese population were recruited into this case-control study, including 500 PD patients and 500 healthy controls. The genotype of the CRP +1444C/T polymorphism was tested by Sanger sequencing, and the Hardy-Weinberg equilibrium (HWE) was assessed in the groups. The odds ratios and 95% confidence intervals were calculated to evaluate the strength of any correlations in allelic, dominant, recessive, and additive genetic models. RESULTS The genotypic distribution of the CRP +1444C/T polymorphism was consistent with HWE in controls, and markedly different with cases. The CRP +1444C/T polymorphism was associated with increased PD risk in allelic and dominant models in the overall and male population, but not the female subgroup. CONCLUSION The presence of a CRP +1444C/T polymorphism may be associated with an increased risk of PD in our Chinese population. Given the missing support for a role of this SNP in PD in the pre-existing GWAS, the SNP may not be genuinely associated with PD despite some positive candidate gene studies.

Abstract
INTRODUCTION The present study investigated the association of the rs2794521 polymorphism in the CRP gene in individuals with chronic hepatitis B and C, correlating it with markers of hepatic inflammation, fibrosis scores, viral load, and plasma protein levels. METHODS The study analyzed 185 blood samples obtained from patients with hepatitis B (n=74) and hepatitis C (n=111) and 300 samples from healthy donors. Genotyping was performed by real-time polymerase chain reaction, and protein levels were quantified using the automated immunoturbidimetric method. RESULTS The TT genotype was the most frequent in all studied groups and was associated with higher plasma levels of the protein but not with the progression of liver disease. Low levels of C-reactive protein were associated with increased viremia and scores indicative of severe fibrosis and cirrhosis. CONCLUSIONS The present results demonstrated a close relationship between the ability of the virus to replicate and cause liver damage and low serum concentrations of C-reactive protein. Future research may determine if these results can be interpreted as a possible form of escape for the virus by decreasing its action as an opsonin and decreasing phagocytosis, which are functions of C-reactive protein in the immune response.

Abstract
C-reactive protein (CRP) is an important mediator and a hallmark of the acute-phase response to inflammation. High-sensitivity assays that accurately measure levels of CRP have been recommended for use in risk assessment in ischemic stroke patients. Elevation of CRP during the acute-phase response in intracerebral hemorrhage (ICH) is also associated with the outcomes such as death and vascular complications. However, no association has been found with the increased risk of ICH. The aim of this review is to synthesize the published literature on the associations of CRP with acute ICH both as a risk biomarker and predictor of short- and long-term outcomes as well as its role as a pathogenic determinant. We believe before any clinical utility, a critical appraisal of the strengths and deficiencies of the accumulated evidence is required both to evaluate the current state of knowledge and to improve the design of future clinical studies.

Abstract
OBJECTIVE Heart failure (HF) is a complex medical condition with a multitude of genetic and other factors being involved in the pathogenesis. Emerging evidence points to an involvement of inflammatory mechanisms at least in subgroups of patients. The same is true for depression and depressive symptoms, which have a high prevalence in HF patients and are risk factors for the development and outcomes of cardiovascular disease. METHODS In 936 patients of the Interdisciplinary Network Heart Failure (INH) program, CRP and IL-6 protein blood levels were measured and genetic variants (single nucleotide polymorphisms) of the CRP and IL6 gene analyzed regarding their influence on mortality. RESULTS Less common recessive genotypes of two single nucleotide polymorphisms in the CRP gene (rs1800947 and rs11265263) were associated with significantly higher mortality risk (p < 0.006), higher CRP levels (p = 0.029, p = 0.006) and increased depressive symptoms in the PHQ-9 (p = 0.005, p = 0.003). Variants in the IL-6 gene were not associated with mortality. CONCLUSION Our results hint towards an association of less common CRP genetic variants with increased mortality risk, depressive symptoms and peripheral CRP levels in this population of HF patients thereby suggesting a possible role of the inflammatory system as link between poor prognosis in HF and depressive symptoms.

Abstract
BACKGROUND Cytokines regulate the expression of inflammatory molecules which destabilize the atheromatic plaques. This study focuses on studying the association of inflammatory cytokine polymorphisms like TNF-α -308 (G/A), TNF-β +252 (A/G), IL-6 -174 (G/C) and IL-6 -597 (G/A), and IFN-ɣ +874 (T/A) with coronary artery disease (CAD) among north Indian patients. MATERIALS AND METHODS 143 CAD and 137 normal healthy controls were recruited in this study. DNA extraction was carried out by high salting out method. TNF-α -308 (G/A) (rs1800797), TNF-β +252 (A/G) (rs909253), IL-6 -174 (G/C) (rs1800795), IL6 -597 (G/A) (rs1800797), and IFN-ɣ +874 (T/A) (rs2430561) SNPs were genotyped by TaqMan®SNP genotyping assays. Different statistical analyses were performed using SPSS v 22.0 and SNPStats. p≤0.05 was considered significant. RESULTS Significant risk association with CAD was found for TNF-α -308 (G/A) "A" allele (OR=5.6, CI 1.8-17.4, p=0.001) and TNF-β +252 (A/G) "G" allele (OR=3.4, CI=1.9-6.0, p<0.001). However, no statistical significance was found for IL-6 -174 (G/C) or IL6 -597 (G/A), with CAD. TNF-α -308 (G/A), and TNF-β +252 (A/G) haplotype "GG" "AG" increased CAD risk significantly (GG haplotype, adjusted OR=2.6, CI 1.4-5.0, p=0.003 and AG haplotype OR=8.5, CI 2.2-33.35, p=0.002) after adjustments for age, sex, TC, TG, HDL, APOB, smoking and diet. DISCUSSION The present study found significant risk association for TNF-α -308 (G/A), and TNF-β +252 (A/G) genotypes, alleles and haplotypes, with CAD in a North Indian population.

Despite considerable efforts in research and clinical studies, stroke is still one of the leading causes of death and disability worldwide. Originally, stroke was considered a vascular thrombotic disease without significant immune involvement. However, over the last few decades it has become increasingly obvious that the immune responses can significantly contribute to both tissue injury and protection following stroke. Recently, much research has been focused on the immune system's role in stroke pathology and trying to elucidate the mechanism used by immune cells in tissue injury and protection. Since the discovery of tissue plasminogen activator therapy in 1996, there have been no new treatments for stroke. For this reason, research into understanding how the immune system contributes to stroke pathology may lead to better therapies or enhance the efficacy of current treatments. Here, we discuss the contrasting roles of immune cells to stroke pathology while emphasizing myeloid cells and T cells. We propose that focusing future research on balancing the beneficial-versus-detrimental roles of immunity may lead to the discovery of better and novel stroke therapies.

Abstract
Background This meta-analysis investigated the correlation of ABCA1 R219K and CRP +1059G/C gene polymorphisms with susceptibility to coronary heart disease (CHD). Material/Methods We searched PubMed, Springer link, Wiley, EBSCO, Ovid, Wanfang database, VIP database, and China National Knowledge Infrastructure (CNKI) databases to retrieve published studies by keyword. Searches were filtered using our stringent inclusion and exclusion criteria. Resultant high-quality data collected from the final selected studies were analyzed using Comprehensive Meta-analysis 2.0 software. Eleven case-control studies involving 3053 CHD patients and 3403 healthy controls met our inclusion criteria. Seven studies were conducted in Asian populations, 3 studies were done in Caucasian populations, and 1 was in an African population. Results Our major finding was that ABCA1 R219K polymorphism increased susceptibility to CHD in allele model (OR=0.729, 95% CI=0.559~0.949, P=0.019) and dominant model (OR=0.698, 95% CI=0.507~0.961, P=0.027). By contrast, we were unable to find any significant association between the CRP +1059G/C polymorphism and susceptibility to CHD (allele model: OR=1.170, 95% CI=0.782~1.751, P=0.444; dominant model: OR=1.175, 95% CI=0.768~1.797, P=0.457). Conclusions This meta-analysis provides convincing evidence that polymorphism of ABCA1 R219K is associated with susceptibility to CHD while the CRP +1059G/C polymorphism appears to have no correlation with susceptibility to CHD.

Abstract
Crohn's disease is often treated with the anti-tumor necrosis factor-α drug adalimumab. However, about 20%-40% of patients do not display adequate therapeutic response. We prospectively evaluated, during a routine therapy of Crohn's disease patients, the candidate autophagy-related genes ATG12 and ATG5 and the inflammation-related genes NFKB1, NFKBIA, and CRP as potential predictors of adalimumab treatment response (pharmacodynamics). The associations of haplotypes and SNPs in these genes with response to drug therapy, biochemical parameters, and body mass were determined at baseline and after 4, 12, 20, and 30 weeks of therapy. Association analysis showed that haplotypes defined with the SNPs rs9373839 and rs510432 in ATG5 gene were significantly associated with positive response to therapy (p < 0.002). In addition, allele C and genotypes CC and CT of the rs1130864 in the CRP gene were positively associated with therapeutic response (p < 0.002). To the best of our knowledge, this is the first report that supports the association of SNPs in ATG5 and CRP genes with response to adalimumab therapy in Crohn's disease. Further study of these biological pathways in larger and independent clinical samples is warranted as novel streams of research on precision medicine and diagnostics for Crohn's disease.

Abstract
BACKGROUND The C-reactive protein (CRP) and the tumor necrosis factor-alpha (TNF-α) are considered markers of inflammation and have been shown to predict the risk of incident cardiovascular events. However, few studies have undertaken a comprehensive examination of SNPs (single nucleotide polymorphisms) of the CRP and TNF-α genes; due to this, we will present a protocol study to evaluate the role of the CRP and TNF-α genes in Mexican individuals. METHODS/DESIGN we will perform a case-control study to explore the CRP and TNF-α genotype distribution as well as the serum influence of rs1800947, rs1130864, rs2794521 and rs1205 (polymorphisms of the CRP gene) and rs361525, rs1800629, rs1799724, rs1800630, rs1799964 (of the TNF-α gene) in Mexican individuals who present coronary artery disease. ETHICS AND DISSEMINATION a written informed consent will be obtained from all the participating subjects. An article detailing the results of the study will be submitted for publication in an international peer-reviewed journal, in accordance with STROBE criteria.

Variants of the Coagulation and Inflammation Genes Are Replicably Associated with Myocardial Infarction and Epistatically Interact in Russians. PLoS One 2015; 10:e0144190. [PMID: 26658659 PMCID: PMC4675542 DOI: 10.1371/journal.pone.0144190] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2015] [Accepted: 11/13/2015] [Indexed: 12/28/2022] Open
Abstract
Background In spite of progress in cardiovascular genetics, data on genetic background of myocardial infarction are still limited and contradictory. This applies as well to the genes involved in inflammation and coagulation processes, which play a crucial role in the disease etiopathogenesis. Methods and Results In this study we found genetic variants of TGFB1, FGB and CRP genes associated with myocardial infarction in discovery and replication groups of Russian descent from the Moscow region and the Republic of Bashkortostan (325/185 and 220/197 samples, correspondingly). We also found and replicated biallelic combinations of TGFB1 with FGB, TGFB1 with CRP and IFNG with PTGS1 genetic variants associated with myocardial infarction providing a detectable cumulative effect. We proposed an original two-component procedure for the analysis of nonlinear (epistatic) interactions between the genes in biallelic combinations and confirmed the epistasis hypothesis for the set of alleles of IFNG with PTGS. The procedure is applicable to any pair of logical variables, e.g. carriage of two sets of alleles. The composite model that included three single gene variants and the epistatic pair has AUC of 0.66 both in discovery and replication groups. Conclusions The genetic impact of TGFB1, FGB, CRP, IFNG, and PTGS and/or their biallelic combinations on myocardial infarction was found and replicated in Russians. Evidence of epistatic interactions between IFNG with PTGS genes was obtained both in discovery and replication groups.
