Rolver MG, Emanuelsson F, Nordestgaard BG, Benn M. Contributions of elevated CRP, hyperglycaemia, and type 2 diabetes to cardiovascular risk in the general population: observational and Mendelian randomization studies. Cardiovasc Diabetol 2024; 23:165. [PMID: 38730445 PMCID: PMC11088022 DOI: 10.1186/s12933-024-02207-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Accepted: 03/18/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVE To investigate the contributions of low-grade inflammation measured by C-reactive protein (CRP), hyperglycaemia, and type 2 diabetes to risk of ischemic heart disease (IHD) and cardiovascular disease (CVD) death in the general population, and whether hyperglycaemia and high CRP are causally related. RESEARCH DESIGN AND METHODS Observational and bidirectional, one-sample Mendelian randomization (MR) analyses in 112,815 individuals from the Copenhagen General Population Study and the Copenhagen City Heart Study, and bidirectional, two-sample MR with summary level data from two publicly available consortia, CHARGE and MAGIC. RESULTS Observationally, higher plasma CRP was associated with stepwise higher risk of IHD and CVD death, with hazard ratios and 95% confidence intervals (95%CI) of 1.50 (1.38, 1.62) and 2.44 (1.93, 3.10) in individuals with the 20% highest CRP concentrations. The corresponding hazard ratios for elevated plasma glucose were 1.10 (1.02, 1.18) and 1.22 (1.01, 1.49), respectively. Cumulative incidences of IHD and CVD death were 365% and 592% higher, respectively, in individuals with both type 2 diabetes and plasma CRP ≥ 2 mg/L compared to individuals without either. Plasma CRP and glucose were observationally associated (β-coefficient: 0.02 (0.02, 0.03), p = 3 × 10- 20); however, one- and two-sample MR did not support a causal effect of CRP on glucose (-0.04 (-0.12, 0.32) and - 0.03 (-0.13, 0.06)), nor of glucose on CRP (-0.01 (-0.08, 0.07) and - 0.00 (-0.14, 0.13)). CONCLUSIONS Elevated concentrations of plasma CRP and glucose are predictors of IHD and CVD death in the general population. We found no genetic association between CRP and glucose, or vice versa, suggesting that lowering glucose pharmacologically does not have a direct effect on low-grade inflammation.

Abstract
GOAL The objective of this study was to evaluate for potential predictors and etiologies of clinical relapse among patients with ulcerative colitis in deep remission. BACKGROUND Patients displaying deep (endoscopic and histologic) remission have a decreased cumulative risk of relapse in ulcerative colitis of <10% per year, but predictors and etiologies of relapse in this population are poorly understood. MATERIALS AND METHODS We performed a retrospective cohort study utilizing electronic medical records at Tufts Medical Center to identify patients in deep remission, classified as having both endoscopic remission (Mayo Endoscopic Score of 0 or 1) and histologic remission (Simplified Geboes Score 0.2). We evaluated the cumulative risk of clinical relapse following attainment of deep remission and examined predictors and etiologies of relapse. RESULTS Among 139 patients with ulcerative colitis in deep remission, the cumulative risk of relapse was <10% and <20% at 1 and 2 years. Patients with complete normalization of mucosa (Geboes=0) and normalization of C-reactive protein (<7.48 mg/dL) at the time of remission were associated with a lower risk of relapse. Discontinuation of therapy was the most commonly identified etiology of relapse. CONCLUSIONS Patients in deep remission have a 1-year risk of clinical relapse of <10%, with those demonstrating a non-normalized mucosa or elevated C-reactive protein predictive of persistent relapse risk. Discontinuation of therapy or minor histologic changes may drive relapse among those in deep remission.

Abstract
BACKGROUND/AIMS Evidence on predictors of primary nonresponse (PNR), and secondary loss of response (SLR) to anti-tumor necrosis factor (anti-TNF) agents in inflammatory bowel disease is scarce from Asia. We evaluated clinical/biochemical/molecular markers of PNR/SLR in ulcerative colitis (UC) and Crohn's disease (CD). METHODS Inflammatory bowel disease patients treated with anti-TNF agents (January 2005-October 2020) were ambispectively included. Data concerning clinical and biochemical predictors was retrieved from a prospectively maintained database. Immunohistochemistry for expression of oncostatin M (OSM), OSM receptor (OSM-R), and interleukin-7 receptor (IL-7R) were done on pre anti-TNF initiation mucosal biopsies. RESULTS One-hundred eighty-six patients (118 CD, 68 UC: mean age, 34.1±13.7 years; median disease duration at anti-TNF initiation, 60 months; interquartile range, 28-100.5 months) were included. PNR was seen in 17% and 26.5% and SLR in 47% and 28% CD and UC patients, respectively. In CD, predictors of PNR were low albumin (P<0.001), postoperative recurrence (P=0.001) and high IL-7R expression (P<0.027) on univariate; and low albumin alone (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.03-0.28; P<0.001) on multivariate analysis respectively. Low albumin (HR, 0.31; 95% CI, 0.15-0.62; P=0.001) also predicted SLR. In UC, predictors of PNR were low albumin (P<0.001), and high C-reactive protein (P<0.001), OSM (P<0.04) and OSM-R (P=0.07) stromal expression on univariate; and low albumin alone (HR, 0.11; 95% CI, 0.03-0.39; P=0.001) on multivariate analysis respectively. CONCLUSIONS Low serum albumin at baseline significantly predicted PNR in UC and PNR/SLR in CD patients. Mucosal markers of PNR were high stromal OSM/OSM-R in UC and high IL-7R in CD patients.

Abstract
OBJECTIVES We aimed to determine whether changes in acute severe colitis (ASC) management have translated to improved outcomes and to develop a simple model predicting steroid non-response on admission. DESIGN Outcomes of 131 adult ASC admissions (117 patients) in Oxford, UK between 2015 and 2019 were compared with data from 1992 to 1993. All patients received standard treatment with intravenous corticosteroids and endoscopic disease activity scoring (Ulcerative Colitis Endoscopic Index of Severity (UCEIS)). Steroid non-response was defined as receiving medical rescue therapy or surgery. A predictive model developed in the Oxford cohort was validated in Australia and India (Gold Coast University Hospital 2015-2020, n=110; All India Institute of Medical Sciences, New Delhi 2018-2020, n=62). RESULTS In the 2015-2019 Oxford cohort, 15% required colectomy during admission vs 29% in 1992-1993 (p=0.033), while 71 (54%) patients received medical rescue therapy (27% ciclosporin, 27% anti-tumour necrosis factor, compared with 27% ciclosporin in 1992-1993 (p=0.0015). Admission C reactive protein (CRP) (false discovery rate, p=0.00066), albumin (0.0066) and UCEIS scores (0.015) predicted steroid non-response. A four-point model was developed involving CRP of ≥100 mg/L (one point), albumin of ≤25 g/L (one point), and UCEIS score of ≥4 (1 point) or ≥7 (2 points). Patients scoring 0, 1, 2, 3 and 4 in the validation cohorts had steroid response rates of 100, 75.0%, 54.9%, 18.2% and 0%, respectively. Scoring of ≥3 was 84% (95% CI 0.70 to 0.98) predictive of steroid failure (OR 11.9, 95% CI 10.8 to 13.0). Colectomy rates in the validation cohorts were were 8%-11%. CONCLUSIONS Emergency colectomy rates for ASC have halved in 25 years to 8%-15% worldwide. Patients who will not respond to corticosteroids are readily identified on admission and may be prioritised for early intensification of therapy.

Abstract
Major Depressive Disorder (MDD) and Bipolar Disorder Depression (BDD) are common psychiatric illnesses characterized by structural and functional brain alterations and signs of neuroinflammation. In line with the neuroinflammatory pathogenesis of depressive syndromes, recent studies have demonstrated how white matter (WM) microstructural impairments detected by Diffusion Tensor Imaging, are correlated to peripheral immunomarkers in depressed patients. In this context, we performed a comprehensive systematic search on PubMed, Medline and Scopus of the original studies published till June 2022, exploring the association between immunomarkers and WM alteration patterns in patients affected by MDD or BDD. Overall, the studies included in this review showed a consistent association between blood proinflammatory and counter-regulatory immunomarkers, including regulatory T cells and natural killer cells markers, as well as measures of demyelination and dysmyelination in both MDD and BDD patients. These pathogenetic insights could outline an integrated clinical perspective to affective disorders, helping psychiatrists to develop novel biotype-to-phenotype models of depression and opening the way to tailored approaches in treatments.

Abstract
BACKGROUND There have been many reports on biomarkers for predicting the severity of acute pancreatitis (AP), but few studies on biomarkers for predicting complications; some simple and inexpensive indicators, in particular, are worth exploring. METHODS We retrospectively collected clinical data of 809 AP patients, including medical history and results of routine blood tests, and grouped them according to the occurrence of complications. Differences in clinical characteristics between groups with and without complications were compared using t-test or χ2 test. Receiver operating curve (ROC) and area under the curve were calculated to evaluate the ability of predicting the occurrence of complications for the routine blood parameters with statistical differences. Then, through univariate and multivariate analyses, independent risk factors closely associated with complications were identified. Finally, we built a three-parameter prediction system and evaluated its ability to predict AP complications. RESULTS Compared with the group without complications, the patients in the complication group had higher white blood cells, neutrophils, C-reactive protein, and erythrocyte sedimentation rate (ESR), and lower red blood cells and hemoglobin (Hb) (all p < .05), and most of them had severe pancreatitis. In addition, pseudocysts were more common in patients with alcoholic etiology, recurrence, low BMI, and high platelet (PLT) and plateletocrit. Acute respiratory failure was more common in patients with first onset and high mean PLT volume (MPV). Sepsis was more common in patients with lipogenic etiology, high MPV, and low lymphocytes. Infectious pancreatic necrosis was more common in patients with alcoholic etiology. Acute renal failure was more common in patients with monocytes and high MPV and low PLT. Multivariate analysis showed that PLT and ESR were risk factors for pseudocyst development. The ROC showed that the combination of Hb, PLT and ESR had a significantly higher predictive ability for pseudocyst than the single parameter. CONCLUSION Routine blood parameters can be used to predict the complications of AP. A predictive model combining ESR, PLT, and Hb may be an effective tool for identifying pseudocysts in AP patients.

Abstract
INTRODUCTION Increased plasma levels of C-reactive protein (CRP) in midlife are associated with increased risk of Alzheimer's disease (AD), whereas in older age the opposite association is observed. Whether genetically determined CRP is associated with AD remains unclear. METHODS A total of 111,242 White individuals from the Copenhagen General Population Study and the Copenhagen City Heart Study were included. Plasma levels of CRP and four regulatory genetic variants in the CRP gene were determined. RESULTS For CRP percentile group 1 to 5 (lowest plasma CRP) versus the 50 to 75 group (reference), the hazard ratio for AD was 1.69 (95% confidence interval 1.29-2.16). Genetically low CRP was associated with increased risk of AD in individuals with body mass index ≤25 kg/m2 (P = 4 × 10-6 ). DISCUSSION Low plasma levels of CRP at baseline were associated with high risk of AD in individuals from the general population. These observational findings were supported by genetic studies.

Genetic variation in C-reactive protein (CRP) gene is associated with retinopathy and hypertension in adolescents with type 1 diabetes. Cytokine 2022; 160:156025.

Abstract
BACKGROUND AND AIMS Elevated concentration of CRP has been associated with the risk of diabetes as well as cardiovascular events and microvascular complications in T1D patients. We hypothesize that the +1846 C > T CRP gene polymorphism may have impact on the risk of T1D and/or its complications. METHODS We have examined 400 young patients with T1D and 250 healthy age-matched controls. The +1846 C > T CRP gene polymorphism was genotyped by ARMS-PCR method. The analysis covers microvascular complications, concentrations of serum pro- and anti-inflammatory markers, adhesion molecules, proangiogenic factor as well as blood pressure. RESULTS CT genotype (OR = 1.799) and T allele (OR = 1.733) are associated with increased risk of T1D, while CC genotype decreases the risk of this condition (OR = 0.458). Moreover, increased risk of hypertension corresponds with TT and T variant (OR = 3.116 and OR = 1.830, resp.) while CC genotype is decreasing the risk (OR = 0.547). Furthermore, CT variant is connected with lower risk of retinopathy (OR = 0.512) whereas TT variant decreases the risk of this complication (OR = 2.228). Our data also implies various effects of CRP +1846 C > T polymorphism on the inflammatory status of T1D patients. CONCLUSIONS Although further studies are required, the +1846 C > T CRP gene polymorphism could be considered a genetic marker to predict susceptibility to retinopathy and hypertension in T1D adolescents.

Abstract
Chronic inflammation contributes significantly to the development and progression of atherosclerosis. However, the factors that lead to an inflammatory imbalance towards a proinflammatory state are not yet fully understood. The CRP rs1800947, TNFA rs1800629, and IL6 rs1800795 polymorphisms may play a role in the pathogenesis of atherosclerosis and were therefore selected to investigate the influence of genetic variability on the corresponding plasma levels after treatment with a proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor. A group of 69 patients with stable coronary artery disease after myocardial infarction before the age of 50 years and very high lipoprotein(a) levels were enrolled in the study. All patients received a PCSK9 inhibitor (evolocumab or alirocumab). Genotyping was performed using TaqMan assays (CRP rs1800947, TNFA rs1800629, and IL6 rs1800795). Consistent with previous studies, no significant change in levels of inflammatory biomarkers was observed after 6 months of treatment with PCSK9 inhibitors. We also did not detect any significant association between single nucleotide polymorphisms CRP rs1800947, TNFA rs1800629, and IL6 rs1800795 and plasma levels of high-sensitivity C-reactive protein (hsCRP), tumor necrosis factor-α (TNF-α), or interleukin 6 (IL6), respectively, at enrollment. However, the difference in IL6 levels after treatment with PCSK9 inhibitors was statistically significant (p = 0.050) in patients with IL6-74CC genotype, indicating the possible role of the IL6 rs1800795 polymorphism in modulating inflammation.

Abstract
Breaking through the biologic therapy efficacy plateau for inflammatory bowel disease requires the strategic development of personalized biomarkers in the tight control model. After risk stratification early in the disease course, targeted serial monitoring consistently to assess clinical outcomes in response to therapy allows for quick therapeutic adjustments before bowel damage can occur. Point-of-care intestinal ultrasound performed by the treating gastroenterologist is an accurate cross- sectional biomarker that monitors intestinal inflammation in real-time, enhances patient care, and increases shared understanding to help achieve common treatment goals. Combining intestinal ultrasound during a clinic visit with existing serum and stool biomarkers in a home testing setup with electronic health monitoring allows for an optimized, patient-centered personalized treatment algorithm that may improve treatment outcomes. Here, we review the current state, pragmatic considerations, and future implications of point-of-care testing and home testing for noninvasive inflammatory bowel disease monitoring in the tight control model.

Abstract
Background Increased neck circumference, a proxy for upper‐body subcutaneous fat, is associated with cardiovascular risk and metabolic risk factors, accounting for body mass index (BMI) and waist circumference. The association between neck circumference and incident atrial fibrillation (AF) is unclear. The aim of current study was to evaluate the association between neck circumference and incident AF. Methods and Results We selected participants from the Framingham Heart Study aged ≥55 years without diagnosed AF and with available neck circumference, BMI, and waist circumference measurements. We defined high neck circumference as ≥14 inches in women and ≥17 inches in men on the basis of the Contal and O’Quigley changepoint method. We used Fine‐Gray models to estimate subdistribution hazards ratios (sHRs) for the association between neck circumference and incident AF accounting for the competing risk of death. We adjusted models for clinical risk factors. We then additionally adjusted separately for BMI, waist circumference, and height/weight. The study sample included 4093 participants (mean age 64±7 years, 55% female). During 11.2±5.7 mean years of follow‐up, incident AF occurred in 571 participants. High neck circumference was associated with incident AF (sHR for high versus low: 1.58; 95% CI, 1.32–1.90, P<0.0001). The association remained significant after adjustment for BMI (sHR, 1.51; 95% CI, 1.21–1.89; P=0.0003), waist circumference (sHR, 1.47; 95% CI, 1.18–1.83; P<0.0001), and height/weight (sHR, 1.37; 95% CI, 1.09–1.72; P=0.007). Conclusions High neck circumference was associated with incident AF adjusting for traditional adiposity measures such as BMI and waist circumference.

Abstract
Inflammatory bowel disease (IBD), which includes ulcerative colitis (UC) and Crohn's disease (CD), is characterized by relapse and remission alternately. It remains a great challenge to diagnose and assess disease activity during IBD due to the lack of specific markers. While traditional biomarkers from plasma and stool, such as C-reactive protein (CRP), fecal calprotectin (FC), and S100A12, can be used to measure inflammation, they are not specific to IBD and difficult to determine an effective cut-off value. There is consensus that gut microbiota is crucial for intestinal dysbiosis is closely associated with IBD etiopathology and pathogenesis. Multiple studies have documented differences in the composition of gut microbiota between patients with IBD and healthy individuals, particularly regarding microbial diversity and relative abundance of specific bacteria. Patients with IBD have higher levels of Proteobacteria and lower amounts of Bacteroides, Eubacterium, and Faecalibacterium than healthy individuals. This review summarizes the pros and cons of using traditional and microbiota biomarkers to assess disease severity and treatment outcomes and addresses the possibility of using microbiota-focused interventions during IBD treatment. Understanding the role of microbial biomarkers in the assessment of disease activity and treatment outcomes has the potential to change clinical practice and lead to the development of more personalized therapies.

Abstract
Background Limited data exist on adherence to fecal calprotectin (FCP) testing in patients with inflammatory bowel disease. Methods Completion rates for patients who had at least one FCP test ordered (n = 3082) and a subgroup with C-reactive protein, complete blood count, and Clostridium difficile tests also ordered (n = 1563) were analyzed. Results More patients completed blood than stool tests, with FCP having the poorest adherence of all tests analyzed. Older patients had higher FCP completion rates. No differences were noted in completion rates across age, gender, or ethnicity for blood tests. Conclusions Further studies are needed to develop strategies that improve the uptake of FCP.

Abstract
Inflammatory processes are implicated in the aetiology of Major Depressive Disorder (MDD); however, the relationship between peripheral inflammation, brain structure and depression remains unclear, partly due to complexities around the use of acute/phasic inflammatory biomarkers. Here, we report the first large-scale study of both serological and methylomic signatures of CRP (considered to represent acute and chronic measures of inflammation respectively) and their associations with depression status/symptoms, and structural neuroimaging phenotypes (T1 and diffusion MRI) in a large community-based sample (Generation Scotland; NMDD cases = 271, Ncontrols = 609). Serum CRP was associated with overall MDD severity, and specifically with current somatic symptoms- general interest (β = 0.145, PFDR = 6 × 10-4) and energy levels (β = 0.101, PFDR = 0.027), along with reduced entorhinal cortex thickness (β = -0.095, PFDR = 0.037). DNAm CRP was significantly associated with reduced global grey matter/cortical volume and widespread reductions in integrity of 16/24 white matter tracts (with greatest regional effects in the external and internal capsules, βFA= -0.12 to -0.14). In general, the methylation-based measures showed stronger associations with imaging metrics than serum-based CRP measures (βaverage = -0.15 versus βaverage = 0.01 respectively). These findings provide evidence for central effects of peripheral inflammation from both serological and epigenetic markers of inflammation, including in brain regions previously implicated in depression. This suggests that these imaging measures may be involved in the relationship between peripheral inflammation and somatic/depressive symptoms. Notably, greater effects on brain morphology were seen for methylation-based rather than serum-based measures of inflammation, indicating the importance of such measures for future studies.

Association of CRP genetic variation with symptomatology, cognitive function, and circulating proinflammatory markers in civilian women with PTSD. J Affect Disord 2021; 279:640-649. [PMID: 33190115 DOI: 10.1016/j.jad.2020.10.045] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 09/08/2020] [Accepted: 10/25/2020] [Indexed: 01/08/2023]
Abstract
BACKGROUND Posttraumatic stress disorder (PTSD) has been associated with increased inflammation. C-reactive protein (CRP) is a marker of systemic inflammation, and recently, single nucleotide polymorphisms (SNPs) in the CRP gene have been associated with increased blood CRP protein levels and illness severity in PTSD patients. However, the mechanism by which the CRP SNPs are involved in PTSD remains unclear. Here we investigated the association of CRP genetic variation with blood proinflammatory protein levels, symptomatology, and cognitive function, and further explored the moderating effect of childhood maltreatment history, in adult patients with PTSD. METHODS Fifty-seven Japanese civilian women with PTSD and 73 healthy control women were enrolled. Three SNPs in the CRP gene, namely rs2794520, rs1130864, and rs3093059, were genotyped, and analyses focused on rs2794520 (T/C). Serum levels of high-sensitivity CRP (hsCRP), high-sensitivity tumor necrosis factor-α (hsTNF-α), and interleukin-6 were measured. PTSD symptoms were evaluated by the Posttraumatic Diagnostic Scale. Cognitive function was assessed by the Repeatable Battery for the Assessment of Neuropsychological Status. Childhood maltreatment history was assessed by the Childhood Trauma Questionnaire. RESULTS Patients with the rs2794520 CC/CT genotype, compared to those with the TT genotype, showed significantly higher levels of hsCRP (p=0.009) and hsTNF-α (p=0.001), more severe PTSD symptoms (p=0.036), and poorer cognitive function (p=0.018). A two-way analysis of variance revealed a significant genotype-by-maltreatment interaction for more severe PTSD avoidance symptom (p=0.012). LIMITATIONS The relatively small sample size limited our findings. CONCLUSIONS These findings may provide an insight into the etiology of PTSD from the inflammatory perspective.

Abstract
Ulcerative colitis is an inflammatory condition of the colon. The diagnosis of ulcerative colitis is based on clinical presentation, endoscopic evaluation, and histologic parameters in the absence of demonstrable alternate etiology. The differential diagnosis remains broad, and infection in particular must be considered and excluded. Although laboratory and radiographic findings can aid in the diagnosis of ulcerative colitis, endoscopy remains the gold standard for diagnosis. A correct diagnosis and disease staging are imperative because these factors affect treatment options and prognosis.

Abstract
BACKGROUND/AIM C-Reactive protein (CRP) is a common marker of inflammation. Elevated CRP levels have been associated with increased risk of development of type 2 diabetes mellitus (T2DM). This study aimed to evaluate the association of CRP gene polymorphisms with early-onset T2DM and the effect of genetic variants on CRP level. MATERIALS AND METHODS In total, 948 individuals with early-onset (n=271) or late-onset (n=677) T2DM were enrolled in the study. Five single-nucleotide polymorphisms (SNPs) in the CRP gene, namely rs3093077, rs2808630, rs1800947, rs11265263, and rs11265265, were selected for genotyping, and CRP levels were measured. RESULTS Genotypic, allelic, and haplotype frequencies of these five SNPs were not significantly different between patients with early- and those with late-onset. T2DM Higher serum CRP levels were independently associated with the C-allele of rs3093077 and T-allele of rs11265265 (p<0.001). Furthermore, the C-allele of rs3093077 was associated with higher CRP level in both early- (p=0.016) and late-onset (p<0.001) T2DM. CONCLUSION CRP gene variants may contribute to the risk of early-onset T2DM by affecting the serum CRP level.

Abstract
OBJECTIVE The prognostic value of high-sensitivity C-reactive protein (hsCRP) and obesity in patients with coronary artery disease is controversial. In previous studies, hsCRP was significantly associated with BMI. Thus, we integrated hsCRP and BMI to assess the predictive value in patients with acute coronary syndrome (ACS). METHODS AND RESULTS In this observational cohort study, 478 patients with ACS were enrolled in Fuwai Hospital from 2010 to 2011,with a mean follow-up of 4.2 years. The endpoint of major adverse cardiovascular events (MACE) was the composite of cardiovascular death, myocardial infarction, revascularization again, heart failure, or stroke. Compared with patients without MACE, we found that patients with MACE had higher hsCRP (3.86 ± 3.66 vs. 3.00 ± 3.17, P = 0.033). Furthermore, we identified that hsCRP was significantly correlated with BMI (r = 0.134, P = 0.005). Thus, hsCRP level was adjusted by BMI to further clarify its role in the prognosis of patients with ACS. According to the tertiles of hsCRP/BMI ratio, the rates of MACE in the lowest tertile group, the median tertile group, and the highest tertile group were 14.0% (21/150), 14.0% (21/150), and 26% (39/150) (P = 0.008), respectively. In multivariate analysis, hsCRP/BMI was independently and positively related to MACE. Similarly, according to risk category of hsCRP (low hsCRP group < 3.0 mg/l, high hsCRP group ≥ 3.0 mg/l) and BMI (< 24 and ≥ 24.0 kg/m), patients in the high hsCRP but normal or low weight group had the lowest MACE-free survival (log-rank P = 0.003) compared with other groups. CONCLUSION We confirmed that C-reactive protein level should be adjusted by BMI to reflect the prognosis of patients with ACS. High hsCRP/BMI ratio was associated with adverse outcomes. Patients with ACS with high hsCRP plus overweight had the same risk for MACE as those with lower hsCRP but normal weight.

Abstract
BACKGROUND Inflammation may play an important role in depression and its treatment. A previous study found that increased C-reactive protein (CRP), a marker of systemic inflammation, is associated with worse response to the serotonergic antidepressant escitalopram and better response to the noradrenergic antidepressant nortriptyline. It is unclear whether this reflects genetic disposition to inflammation. METHODS We analyzed genotype data and weekly Montgomery-Åsberg Depression Rating Scale scores (MADRS) from 755 unrelated individuals obtained over a 12-week period in the Genome-Based Therapeutic Drugs for Depression (GENDEP) study. We calculated a polygenic risk score for CRP level based on genome-wide meta-analysis results from the CHARGE Consortium. RESULTS A higher polygenic risk score for CRP was associated with slightly better response to escitalopram and slightly worse response to nortriptyline, reflected in a statistically significant interaction between polygenic risk score and drug (beta = 1.07, 95% CI = 0.26-1.87, p = 0.0093). DISCUSSION A differential association between CRP-PRS and antidepressant drug that is in a direction opposite to that found with serum CRP measurement suggests that previously observed effect of inflammation on antidepressant efficacy may be driven by state factors distinct from genetic influences on systemic inflammation.

Abstract
OBJECTIVE Middle-aged adults who are lonely have an elevated likelihood of death. Systemic inflammation may contribute to these increased odds. Using population-level data, this study tested if systemic inflammation is associated with loneliness in a broad age range of middle-aged adults in the United States. METHODS This study used data from the Midlife in the US (MIDUS) survey Biomarker Project, which collected data on psychological, social, and physiological measures from a sample of middle-aged adults. This sample included the 927 participants who were 35-64 years at Biomarker Project data collection. MIDUS collected baseline data from 1995-1996 and a follow-up survey was conducted from 2004-2006. The baseline Milwaukee sample of African Americans was collected in 2005-2006 and the biomarker database was collected in 2004-2009. Biomarkers were obtained from a fasting blood sample. Self-reported loneliness was categorized as feeling lonely or not feeling lonely. Hierarchical regressions examined the association between biomarkers of systemic inflammation (interleukin-6, fibrinogen, C-reactive protein) and feeling lonely, adjusted for covariates. RESULTS Twenty-nine percent of the sample reported feeling lonely most or some of the time. There was a positive significant relationship between loneliness and the three systemic inflammation biomarkers after controlling for covariates: interleukin-6 (n = 873) (b [se] = 0.07 [0.03], p = .014); fibrinogen (n = 867) (b [se] = 18.24 [7.12], p = .011); and C-reactive protein (n = 867) (b [se] = 0.08 [0.04], p = .035). CONCLUSIONS Feeling lonely is associated with systemic inflammation in middle-aged community-dwelling US adults.

Abstract
High-sensitivity C-reactive protein (hsCRP) is an inflammatory marker for the prediction and prognosis of ischemic stroke but there is an absence of evidence for cerebral hemorrhagic events. The aim of this study is to investigate the effects of elevated plasma hsCRP and CRP genetic variants on hemorrhagic stroke (HS). Two hundred thirty-six inpatients with HS and 993 age-matched controls from a community-based population were included in a case-control study and four tagging single nucleotide polymorphsims (tagSNPs) at CRP were genotyped. The association of hsCRP elevation and CRP variants with HS was evaluated by multiple logistic regression. HS cases had a higher median (interquartile) of hsCRP with 5.40 (1.30-10.7) mg/L and a proportion of hsCRP elevation (≥3 mg/L, 63.4%) than controls [1.20 (0.80-2.20) mg/L, 16.6%], respectively (P < 0.05 for all). No significant difference of genotype or allele frequency of the four SNPs was observed between HS patients and controls (P > 0.05). Further stratified analysis by gender showed that the variants of rs3093059 (T/C) and rs3091244 (C/T/A) were significantly associated with the decreased risk of HS in men and odds ratios (ORs) and 95% confidence intervals (95% CIs) for additive models were 0.515 (0.294-0.903) and 0.578 (0.349-0.96), respectively, after adjusting for covariates. In HS patients, rs3091244 was positively associated with the hsCRP elevation and rs2794521 was negatively associated with hsCRP elevation (P < 0.05). Our findings suggest that hsCRP elevation is associated with the risk of HS and CRP contributes genetic susceptibility to HS in men as well as hsCRP elevation in HS.

Serum High-Sensitive C-Reactive Protein Level and CRP Genetic Polymorphisms Are Associated with Abdominal Aortic Aneurysm. Ann Vasc Surg 2017; 45:186-192.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) development involves an inflammatory process with a potential genetic background. C-reactive protein (CRP) is an acute phase protein and was elevated in patients with AAA. The aim of this study was to investigate the association among serum high-sensitive CRP (hsCRP) concentration, its CRP genetic polymorphisms, and AAA. METHODS Serum hsCRP concentrations and abdominal aorta diameters were measured, and correlation analysis between them was performed in 155 unrelated participants with AAA and 310 non-AAA controls. Tagging single nucleotide polymorphisms (SNPs) in the CRP gene (rs1417938, rs1130864, rs1205, rs1800947) were identified via HapMap. Stratification analysis was performed to evaluate the effects of SNPs on the concentration of serum hsCRP. The association between 4 SNPs and AAA was assessed by unconditional logistic regressions. RESULTS Elevated serum hsCRP level was found to be an independent risk factor for AAA (odds ratio [OR] = 3.91, 95% confidence interval [CI]: 2.45, 6.23) after adjustment for confounding factors. Concentrations of serum hsCRP were significant different (P = 0.01) in 4 subgroups derived from participants with abdominal aorta diameter <20 mm, 20-29 mm, 30-54 mm, and ≥55 mm. Stratification analysis revealed there was significant high frequency of elevated hsCRP levels in subjects carrying rs1205-CC genotype compared with those carrying rs1205-TT or CT genotypes (P = 0.004, OR = 2.31, 95% CI: 1.30, 4.11), suggesting that the genotype CC of rs1205 was associated with higher serum hsCRP levels. However, the frequency of rs1205-CC in AAA patients (15.3%) was similar to control subjects (17.6%), and we could not confirm rs1205-CC was the genetic risk factor of AAA (OR = 1.18, 95% CI: 0.69, 2.01). Moreover, we found another CRP polymorphism rs1417938-TT had a significantly higher likelihood of AAA than the AT genotype (OR = 2.07, 95% CI: 1.06, 4.03) for the first time, indicating there was perhaps a role for rs14117938-T polymorphism that correlates with AAA. CONCLUSIONS Serum hsCRP may be related to the presence of AAA and abdominal aorta diameter. Genetic polymorphisms in CRP gene could influence the concentration of serum hsCRP and the likelihood of AAA, but the causal relationship between AAA and CRP should be demonstrated further.

Abstract
Crohn's disease and ulcerative colitis are heterogeneous inflammatory bowel diseases, and therapeutic requirements vary among patients. We have a limited capacity to predict disease progression for individual patients, therefore it is important that they are evaluated for the presence of active disease when symptoms are mild or even absent, when patients are more likely to respond to new treatment interventions. It then is important to monitor responses to treatment, to quickly identify those therapies that are ineffective, modify or change therapy, and avoid disease complications. Studies are underway to assess the effects of different monitoring strategies. Because of the heavy burden of severe inflammatory bowel disease on patients' health and quality of life, and the association between intestinal healing and disease progression in high-risk patients, a treat-to-target strategy (based on tissue healing) is likely to be optimal.

Abstract
INTRODUCTION Psoriasis is a multi-factorial heritable T-helper Th-1/Th-17 mediated inflammatory disease, affecting the skin. It is associated with co-morbidities such as Cardiovascular Disease (CVD). C-Reactive Protein (CRP) is a good inflammatory marker. CRP rs1205 polymorphism is associated with circulating plasma CRP levels. Although there is association between the rs1205 Single Nucleotide Polymorphism (SNP) and CVD, there are no prior reports regarding the association of CRP rs1205 SNP with psoriasis susceptibility. AIM To study the association of the genetic variant rs1205 in the CRP gene with susceptibility to the disease and protein levels in South Indian Tamils with psoriasis. MATERIALS AND METHODS In this case-control genetic study, 300 cases of psoriasis and 300 age and gender matched controls were genotyped for CRP SNP rs1205 using Taq Man 5'allele discrimination assay at Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry, India from February 2014 to January 2016. Plasma high sensitivity (hs)-CRP levels were estimated by ELISA. Disease severity was assessed by Psoriasis Area Severity Index (PASI). RESULTS CRP genetic variation rs1205 was not associated with psoriasis risk in our South Indian Tamil population. However, the circulating levels of hs-CRP was significantly higher in patients with psoriasis, as compared with controls (p < 0.0001) and the protein levels were significantly associated with disease severity, as assessed by PASI scoring. No genotype was found significantly associated with PASI or CRP levels. CONCLUSION Our results suggest that plasma CRP levels are higher in patients with psoriasis and correlate with disease severity, whilst CRP rs1205 is not associated with susceptibility to psoriasis in South Indian Tamils.

[PMID: 27580453 DOI: 10.1016/j.cyto.2016.08.021] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 08/16/2016] [Accepted: 08/22/2016] [Indexed: 01/21/2023]
Abstract
BACKGROUND The aim of this analysis was to evaluate the importance of C-reactive protein levels and genetic variants of CRP as prognostic markers for further cardiovascular (CV) events (3-year follow-up) in a cohort of in-patients with cardiovascular disease (CVD) patients. METHODS AND RESULTS Patients with angiographic proven CVD (n=939) were prospectively included. The three-year CV outcome of the patients was evaluated considering the predefined, combined endpoint (CV death, death from stroke, myocardial infarction, and stroke/TIA). Polymorphisms rs1800947, rs1417938, rs1130864, rs3093077 were analysed. In Kaplan-Meier survival curve and Cox regression increased CRP levels of ⩾5mg/l (log-rank test: p=0.001, Cox regression: hazard ratio=1.77, 95% CI: 1.2-2.7) and the GG genotype of rs1800947 (log-rank test: p=0.01, Cox regression: hazard ratio=1.99, 95% CI: 1.1-3.6) were associated with the incidence of the combined endpoint. CONCLUSIONS Both a CRP level ⩾5mg/l and SNP rs1800947 of the CRP gene were independent risk factors for further adverse CV events among patients with CVD within three years follow-up.

Abstract
In the past, laboratory tests were considered of limited value in Crohn's disease (CD). In the era of biologics, laboratory tests have become essential to evaluate the inflammatory burden of the disease (C-reactive protein, fecal calprotectin) since symptoms-based scores are subjective, to predict the response to pharmacological options and the risk of relapse, to discriminate CD from ulcerative colitis, to select candidates to anti-tumor necrosis factors [screening tests looking for hepatitis B virus and hepatitis C virus status and latent tuberculosis], to assess the risk of adverse events (testing for thiopurine metabolites and thiopurine-methyltransferase activity), and to personalize and optimize therapy (therapeutic drug monitoring). Pharmacogenetics, though presently confined to the assessment of thiopurineme methyltransferase polymorphisms and hematological toxicity associated with thiopurine treatment, is a promising field that will contribute to a better understanding of the molecular mechanisms of the variability in response to the drugs used in CD with the attempt to expand personalized care and precision medicine strategies.

Abstract
BACKGROUND In complex diseases such as chronic kidney disease (CKD), the risk of clinical complications is determined by interactions between phenotypic and genotypic factors. However, clinical epidemiological studies rarely attempt to analyse the combined effect of large numbers of phenotype and genotype features. We have recently shown that the relaxed linear separability (RLS) model of feature selection can address such complex issues. Here, it is applied to identify risk factors for inflammation in CKD. METHODS The RLS model was applied in 225 CKD stage 5 patients sampled in conjunction with dialysis initiation. Fifty-seven anthropometric or biochemical measurements and 79 genetic polymorphisms were entered into the model. The model was asked to identify phenotypes and genotypes that, when combined, could separate inflamed from non-inflamed patients. Inflammation was defined as a high-sensitivity C-reactive protein concentration above the median (5 mg/L). RESULTS Among the 60 genotypic and phenotypic features predicting inflammation, 31 were genetic. Among the 10 strongest predictors of inflammation, 8 were single nucleotide polymorphisms located in the NAMPT, CIITA, BMP2 and PIK3CB genes, whereas fibrinogen and bone mineral density were the only phenotypic biomarkers. CONCLUSION These results indicate a larger involvement of hereditary factors in inflammation than might have been expected and suggest that inclusion of genotype features in risk assessment studies is critical. The RLS model demonstrates that inflammation in CKD is determined by an extensive panel of factors and may prove to be a suitable tool that could enable a much-needed multifactorial approach as opposed to the commonly utilized single-factor analysis.

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.

Int J Mol Sci 2015; 16:23745-59. [PMID: 26473826 PMCID: PMC4632724 DOI: 10.3390/ijms161023745] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2015] [Revised: 08/28/2015] [Accepted: 08/31/2015] [Indexed: 02/04/2023] Open
Abstract
Elevation in C-reactive protein (CRP) levels have been shown in patients with aortic valve stenosis (AS). Minor allele of the CRP gene (CRP) rs1205 C>T polymorphism has been associated with lower plasma CRP concentrations in cohorts of healthy and atherosclerotic patients. Considering the existing similarities between atherosclerosis and AS, we examined the effect of CRP rs1205 C>T polymorphism on the AS severity. Three hundred consecutive Caucasian patients diagnosed with AS were genotyped for the rs1205 C>T polymorphism using the TaqMan assay. Severity of the AS was assessed using transthoracic echocardiography. The degree of calcification was analyzed semi-quantitatively. Carriers of the rs1205 T allele were characterized by elevated serum CRP levels (2.53 (1.51-3.96) vs. 1.68 (0.98-2.90) mg/L, p<0.001) and a higher proportion of the severe aortic valve calcification (70.4% vs. 55.1%, p=0.01) compared with major homozygotes. The effect of CRP rs1205 polymorphism on CRP levels is opposite in AS-affected than in unaffected subjects, suggesting existence of a disease-specific molecular regulatory mechanism. Furthermore, rs1205 variant allele predisposes to larger aortic valve calcification, potentially being a novel genetic risk marker of disease progression.

Abstract
BACKGROUND We tested the hypotheses that fibrinogen and α1-antitrypsin are observationally and genetically associated with exacerbations in COPD. METHODS We studied 13,591 individuals with COPD from the Copenhagen General Population Study (2003-2013), of whom 6857 were genotyped for FGB -455 (rs1800790, G>A) and FGB -448 (rs4220, G>A) and had plasma fibrinogen measured. Furthermore, 13,405 individuals were genotyped for the SERPINA1 S-allele (rs17580) and the Z-allele (rs28929474) and had measurements of plasma α1-antitrypsin. Exacerbations were defined as hospital admissions or treatments with systemic corticosteroids. We studied observational associations between plasma measurements and exacerbations in Cox regression analyses, associations between genotypes and exacerbations in logistic regression analyses and associations between genetically determined plasma levels and exacerbations in instrumental variable analyses. RESULTS Elevated fibrinogen and α1-antitrypsin levels were associated with increased risk of exacerbations in COPD, HR=1.14 (1.07 to 1.22, p<0.001) and 1.18 (1.11 to 1.25, p<0.001), respectively, per SD increase. Presence of the Z-allele was associated with increased odds of exacerbations, OR=1.25 (1.05 to 1.48, p=0.01), as was α1-antitrypsin level genetically lowered by the Z-allele, OR=1.07 (1.02 to 1.13, p=0.004), per SD decrease. Fibrinogen elevating genotypes, FGB -455 (AA) and FGB -448 (AA), were not associated with exacerbations, OR=0.96 (0.73 to 1.25, p=0.77) and OR=1.01 (0.75 to 1.33, p=0.90), respectively, and neither was genetically elevated fibrinogen level, OR=1.11 (0.76 to 1.63, p=0.58) per SD increase. CONCLUSIONS Fibrinogen and α1-antitrypsin were observationally associated with increased risk of exacerbations. However, genetically, fibrinogen per se was not associated with exacerbations, while lowered α1-antitrypsin was associated with increased odds of exacerbations.

C-Reactive Protein, Fecal Calprotectin, and Stool Lactoferrin for Detection of Endoscopic Activity in Symptomatic Inflammatory Bowel Disease Patients: A Systematic Review and Meta-Analysis. Am J Gastroenterol 2015; 110:802-19; quiz 820.

Abstract
OBJECTIVES Persistent disease activity is associated with a poor prognosis in inflammatory bowel disease (IBD). Therefore, monitoring of patients with intent to suppress subclinical inflammation has emerged as a treatment concept. As endoscopic monitoring is invasive and resource intensive, identification of valid markers of disease activity is a priority. The objective was to evaluate the diagnostic accuracy of C-reactive protein (CRP), fecal calprotectin (FC), and stool lactoferrin (SL) for assessment of endoscopically defined disease activity in IBD. METHODS Databases were searched from inception to November 6, 2014 for relevant cohort and case-control studies that evaluated the diagnostic accuracy of CRP, FC, or SL and used endoscopy as a gold standard in patients with symptoms consistent with active IBD. Sensitivities and specificities were pooled to generate operating property estimates for each test using a bivariate diagnostic meta-analysis. RESULTS Nineteen studies (n=2499 patients) were eligible. The pooled sensitivity and specificity estimates for CRP, FC, and SL were 0.49 (95% confidence interval (CI) 0.34-0.64) and 0.92 (95% CI 0.72-0.96), 0.88 (95% CI 0.84-0.90) and 0.73 (95% CI 0.66-0.79), and 0.82 (95% CI 0.73-0.88) and 0.79 (95% CI 0.62-0.89), respectively. FC was more sensitive than CRP in both diseases and was more sensitive in ulcerative colitis than Crohn's disease. CONCLUSIONS Although CRP, FC, and SL are useful biomarkers, their value in managing individual patients must be considered in specific clinical contexts.

Abstract
OBJECTIVE Increased systemic inflammation is associated with stress-related psychopathology. Specifically, levels of the proinflammatory marker C-reactive protein (CRP) are elevated in individuals with posttraumatic stress disorder (PTSD). Furthermore, single-nucleotide polymorphisms (SNPs) in the CRP gene are associated with CRP level, risk for cardiovascular disease, and obesity. The authors examined whether polymorphisms within the CRP gene and increased CRP levels are associated with PTSD symptoms and fear physiology in a civilian population with high levels of trauma. METHOD Cross-sectional data and DNA samples were collected from 2,698 individuals recruited from an inner-city public hospital that serves a primarily African American, low-socioeconomic-status population. A subgroup of 187 participants participated in further interviews, testing, and physiological measures; of these, 135 were assessed using the fear-potentiated startle paradigm to assess fear-related phenotypes of PTSD. RESULTS One SNP within the CRP gene, rs1130864, was significantly associated with increased PTSD symptoms (N=2,692), including "being overly alert" as the most significant individual symptom (N=2,698). Additionally, CRP genotype was associated with the odds of PTSD diagnosis (N=2,692). This SNP was also associated with increased CRP level (N=137), and high CRP levels (>3 mg/L) were positively associated with PTSD symptoms (N=187) and fear-potentiated startle to a safety signal (N=135). CONCLUSIONS Together, these data indicate that genetic variability in the CRP gene is associated with serum CRP level and PTSD symptom severity, including that of hyperarousal symptoms. Elevated CRP levels were also associated with exacerbated fear-related psychophysiology and PTSD symptom ratings and diagnosis. These findings suggest a potential mechanism by which an increased proinflammatory state may lead to heightened PTSD symptoms.

Abstract
BACKGROUND Coronary Artery Disease (CAD) is clearly a multifactorial disease that develops from childhood and ultimately leads to death. Several reports revealed having a First Degree Relatives (FDRS) with premature CAD is a significant autonomous risk factor for CAD development. C - reactive protein (CRP) is a member of the pentraxin family and is the most widely studied proinflammatory biomarker. IL-18 is a pleiotrophic and proinflammatory cytokine which is produced mainly by macrophages and plays an important role in the inflammatory cascade. METHODS AND RESULTS Hs-CRP levels were estimated by ELISA and Genotyping of IL-18 gene variant located on promoter -137 (G/C) by Allele specific PCR in blood samples of 300 CAD patients and 300 controls and 100 FDRS. Promoter Binding sites and Protein interacting partners were identified by Alibaba 2.1 and Genemania online tools respectively. Hs-CRP levels were significantly high in CAD patients followed by FDRS when compared to controls. In IL-18 -137 (G/C) polymorphism homozygous GG is significantly associated with occurrence of CAD and Hs-CRP levels were significantly higher in GG genotype subjects when compared to GC and CC. IL-18 was found to be interacting with 100 protein interactants. CONCLUSION Our results indicate that Hs-CRP levels and IL-18-137(G/C) polymorphism may help to identify risk of future events of CAD in asymptomatic healthy FDRS.

Abstract
BACKGROUND Genome-wide association studies (GWASs) have successfully identified several single nucleotide polymorphisms (SNPs) associated with serum levels of C-reactive protein (CRP). An important limitation of GWASs is that the identified variants merely flag the nearby genomic region and do not necessarily provide a direct link to the biological mechanisms underlying their corresponding phenotype. Here we apply a bioinformatics-based approach to uncover the functional characteristics of the 18 SNPs that had previously been associated with CRP at a genome-wide significant level. METHODS AND RESULTS In the first phase of in silico sequencing, we explore the vicinity of GWAS SNPs to identify all linked variants. In the second phase of expression quantitative trait loci analysis, we attempt to identify all nearby genes whose expression levels are associated with the corresponding GWAS SNPs. These 2 phases generate several relevant genes that serve as input to the next phase of functional network analysis. Our in silico sequencing analysis using 1000 Genomes Project data identified 7 nonsynonymous SNPs, which are in moderate to high linkage disequilibrium (r(2)>0.5) with the GWAS SNPs. Our expression quantitative trait loci analysis, which was based on one of the largest single data sets of genome-wide expression probes (n>5000) identified 23 significantly associated expression probes belonging to 15 genes (false discovery rate <0.01). The final phase of functional network analysis revealed 93 significantly enriched biological processes (false discovery rate <0.01). CONCLUSIONS Our post-GWAS analysis of CRP GWAS SNPs confirmed the previously known overlap between CRP and lipids biology. Additionally, it suggested an important role for interferons in the metabolism of CRP.

Serum C-reactive protein and CRP genotype in pediatric inflammatory bowel disease: influence on phenotype, natural history, and response to therapy. Inflamm Bowel Dis 2015; 21:596-605.

Abstract
BACKGROUND C-reactive protein (CRP) is an acute phase reactant. Patients with pediatric inflammatory bowel disease (PIBD) differ from adult patients with inflammatory bowel disease with regard to phenotype, inflammatory profile, and treatment response. We hypothesized that variations in CRP and CRP genotype influence PIBD phenotype, natural history, and remission after anti-tumor necrosis factor alpha therapy. METHODS Six single nucleotide polymorphisms tagging CRP (rs1935193, rs1130864, rs1205, rs1417938, rs11265263, and rs1800947) were genotyped in 465 patients with PIBD (diagnosed <17 yr). Phenotyping was serially performed until last follow-up and serum CRP levels recorded at diagnosis and before biological therapy in a subgroup. RESULTS CRP haplotype (ATGCTC) differed in those diagnosed <10 years, with rs1205T more frequent in Crohn's disease (CD) than ulcerative colitis (UC) (P = 0.009); the haplotype ATGCTC was less frequent in UC (P = 0.002). Three single nucleotide polymorphisms (rs1205, rs1130864, and rs1417938) showed association with elevated CRP levels at diagnosis. CRP genotype had no association with CD phenotype or natural history. CRP was more frequently raised at diagnosis in CD than UC (63% versus 22%, P < 0.0001). Elevated CRP at diagnosis was associated with a higher risk of progression to surgery in patients with CD (P < 0.0001) and the need for azathioprine in the overall PIBD cohort (P = 0.002). There was no effect of CRP genotype or serum CRP on the achievement of remission using anti-tumor necrosis factor alpha therapy. CONCLUSIONS CRP and CRP genotype differ between pediatric patients with CD and UC with a high inflammatory burden at diagnosis suggesting a worse prognosis. Additional evaluation of CRP in inflammatory bowel disease pathogenesis and natural history is now warranted.

Abstract
Coronary artery disease (CAD) is mainly caused by atherosclerosis, which is closely associated with the C-reactive protein (CRP), a systemic inflammatory mediator. The aim of the present study was to examine whether the CRP rs2794520 polymorphism played a role in the risk of CAD. A total of 459 CAD patients and 432 non-CAD controls were recruited in the case-control study. Genotyping was performed on the SEQUENOM® Mass-ARRAY iPLEX® platform according to the manufacturer's instructions. The results showed that CRP rs2794520 was not associated with CAD. A further breakdown analysis by age or gender also indicated a lack of association between rs2794520 and CAD. In addition, the CRP rs2794520 polymorphism was not associated with the severity of CAD, which was represented by the number of coronary arteries with stenosis. In conclusion, there was no contribution of the CRP rs2794520 polymorphism to the risk of CAD.

Abstract
Over the years, schizophrenia is speculated to be associated with immune or inflammatory reactions mediated by cytokines. It is proposed that chronic inflammation might damage the micro-vascular system of brain and hamper cerebral blood flow. Scientific evidence suggests that an increase of stress hormone like norepinephrine may activate the inflammatory arm of the immune system and trigger the expression of genes that cause chronic, low-grade inflammation. Thus, studies were conducted to decipher the potentiality of CRP as a marker for inflammation in schizophrenia. This article reviews the findings of CRP in schizophrenia, and the limitations of the previous studies have been discussed. The importance of simultaneous study of CRP modulating cytokines and CRP gene polymorphism in the study of serum or plasma level of CRP has been emphasized.

Abstract
C-reactive protein (CRP) is a general marker of systemic inflammation and cardiovascular disease (CVD). The genetic contribution to differences in CRP levels remains to be explained, especially in non-European populations. Thus, the aim of this study was to identify genetic loci associated with CRP levels in Korean population. We performed genome-wide association studies (GWAS) using SNPs from 8,529 Korean individuals (7,626 for stage 1 and 903 for stage 2). We also performed pathway analysis. We identified a new genetic locus associated with CRP levels upstream of ARG1 gene (top significant SNP: rs9375813, Pmeta = 2.85×10(-8)), which encodes a key enzyme of the urea cycle counteract the effects of nitric oxide, in addition to known CRP (rs7553007, Pmeta = 1.72×10(-16)) and HNF1A loci (rs2259816, Pmeta = 2.90×10(-10)). When we evaluated the associations between the CRP-related SNPs with cardiovascular disease phenotypes, rs9375813 (ARG1) showed a marginal association with hypertension (P = 0.0440). To identify more variants and pathways, we performed pathway analysis and identified six candidate pathways comprised of genes related to inflammatory processes and CVDs (CRP, HNF1A, PCSK6, CD36, and ABCA1). In addition to the previously reported loci (CRP, HNF1A, and IL6) in diverse ethnic groups, we identified novel variants in the ARG1 locus associated with CRP levels in Korean population and a number of interesting genes related to inflammatory processes and CVD through pathway analysis.

Abstract
C-reactive protein (CRP) and coronary heart disease (CHD) have been the subject of intensive investigations over the last decades. Epidemiological studies have shown an association between moderately elevated CRP levels and incident CHD whereas genetic studies have shown that polymorphisms associated with elevated CRP levels do not increase the risk of ischemic vascular disease, suggesting that CRP might be a bystander rather than a causal factor in the progress of atherosclerosis. Beside all those epidemiological and genetic studies, the experimental investigations also try to reveal the role of CRP in the progress of atherosclerosis. This review will highlight the complex results of genomic, epidemiological, and experimental studies on CRP and will show why further studies investigating the relationship between CRP and atherosclerosis might be needed.

Abstract
WHAT IS KNOWN AND OBJECTIVE Pharmacogenetic studies of the genetic regulation of warfarin dose requirement have been reported, but few have been on the bleeding complications at therapeutic international normalized ratio (INR). This study aimed to evaluate the effect of gene polymorphisms of CYP2C9, VKORC1, thrombomodulin (THBD) and C-reactive protein (CRP) on the risk of bleeding complications of warfarin at therapeutic INR in Korean patients with mechanical cardiac valves. METHODS A retrospective warfarin pharmacogenetic association study was performed. One hundred and forty-two patients with mechanical cardiac valves who were on warfarin anticoagulation therapy and maintained INR levels of 2·0-3·0 for 3 consecutive time intervals were followed up. CYP2C9 rs1057910, VKORC1 rs9934438, CRP rs1205, THBD rs1042580 and THBD rs3176123 were genotyped. The association between genotypes and warfarin bleeding complications was evaluated using logistic regression analysis, adjusted for demographic and clinical factors. RESULTS AND DISCUSSION Of 142 eligible patients, 21 patients (14·8%) had bleeding complications at therapeutic INR. Patients with the G allele in THBD rs1042580 (AG or GG) had a lower risk of bleeding than patients with the AA genotype (adjusted OR: 0·210, 95% CI: 0·050-0·875, P = 0·032). The THBD rs3176123 polymorphism did not show any association with bleeding. For CRP rs1205, patients with the A allele (GA or AA genotype) had a higher risk of bleeding than patients with the GG genotype (adjusted OR: 5·575, 95% CI: 1·409-22·058, P = 0·014). Variant VKORC1 and CYP2C9 genotypes did not confer a significant increase in the risk for bleeding complications. WHAT IS NEW AND CONCLUSIONS As expected, no association could be found between bleeding complications and two dose-related genes (CYP2C9*3 and VKORC1 rs9934438). In contrast, our results suggest that two genetic markers (THBD rs1042580 and CRP rs1205) could be predictors of bleeding complications of warfarin at normal INR. Given the retrospective study design and the relatively small sample size, our hypothesis requires further independent validation using more robust prospective designs. However, additional retrospective studies similar to ours but in populations with different genetic backgrounds should also be useful.
