Guaraná WL, Lima CAD, Barbosa AD, Crovella S, Sandrin-Garcia P. Can Polymorphisms in NLRP3 Inflammasome Complex Be Associated with Postmenopausal Osteoporosis Severity? Genes (Basel) 2022; 13:genes13122271. [PMID: 36553538 PMCID: PMC9777825 DOI: 10.3390/genes13122271] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2022] [Revised: 11/25/2022] [Accepted: 11/30/2022] [Indexed: 12/05/2022] Open
Abstract
The immune system plays a critical role in bone homeostasis and, consequently, in the pathophysiology of postmenopausal osteoporosis (OP) since estrogen deficiency induces the inflammasome and increases production of pro-inflammatory cytokines, such as IL-1β and IL-18. NLRP3 inflammasome complex genes have been related with bone homeostasis in cellular and animal models. Here, we performed an association study evaluating SNVs (single-nucleotide variants) in inflammasome NLRP3 pathway genes (NLRP3, CARD8, CASP1, IL-18, and IL-1β) to assess whether variants in these genes could be related to susceptibility to primary OP in postmenopausal women. METHODS We genotyped 196 postmenopausal OP patients and 103 healthy controls using SNV-specific Taqman® probes. Data and statistical analyses were performed using the SNPstats and GraphPad Prism 8 software. RESULTS We showed an association between NLRP3 rs35829419 CA genotype and lower bone mineral density (BMD) mean at the lumbar spine (p = 0.001); we also observed an association between IL-1β rs16944 AA genotype and higher BMD mean at the total hip (p = 0.009). The IL-1β rs16944 GG was associated with lower alkaline phosphatase levels (ALP) (p = 0.009), and the IL-18 rs1946519 AA was associated with lower vitamin D levels (p = 0.018). Additionally, OP patients presented deficient vitamin D and parathyroid hormone (PTH). CONCLUSIONS The NLRP3 inflammasome complex SNVs were associated with OP severity, possibly indicating these genes' participation in bone metabolism and its dysregulation.

Association of TGFB1 rs1800469 and BCMO1 rs6564851 with coronary heart disease and IL1B rs16944 with all-cause mortality in men from the Northern Ireland PRIME study. PLoS One 2022; 17:e0273333. [PMID: 35994463 PMCID: PMC9394803 DOI: 10.1371/journal.pone.0273333] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Accepted: 08/07/2022] [Indexed: 12/03/2022] Open
Abstract
Background Historically, high levels of morbidity and mortality have been associated with cardiovascular disease in the Northern Ireland population. Previously reported associations between single nucleotide polymorphisms (SNPs) and cardiovascular disease within other populations have not always been consistent. Objective To investigate associations between 33 SNPs with fatal or non-fatal incident coronary heart disease (CHD) events and all-cause mortality in the Northern Irish participants of the Prospective Epidemiological Study of Myocardial Infarction (PRIME). Method Phase 2 of the PRIME study prospectively evaluated 2,010 men aged 58–74 years in Northern Ireland for more than 10 years for incident CHD events (myocardial infarction, percutaneous coronary intervention, coronary artery bypass, and cardiac death) and more than 15 years for all-cause mortality. SNPs previously reported in association with cardiovascular outcomes were evaluated against incident CHD events and all-cause mortality using Cox’s proportional hazards models adjusted for established cardiovascular disease risk factors. Results During the follow-up period, 177 incident CHD events were recorded, and 821 men died. Both BCMO1 rs6564851 (Hazard ratio [HR] = 0.76; 95% confidence intervals [CI]: 0.60–0.96; P = 0.02) and TGFB1 rs1800469 (HR = 1.30; CI: 1.02–1.65; P = 0.04) were significantly associated with incident CHD events in adjusted models. Only IL1B rs16944 was significantly associated with all-cause mortality (HR = 1.18; CI: 1.05–1.33; P = 0.005). No associations remained significant following Bonferonni correction for multiple testing. Conclusion We report a novel association between BCMO1 rs6564851 and risk of incident CHD events. In addition, TGFB1 rs1800469 and IL1B rs16944 were associated with the risk of incident CHD events and all-cause mortality outcomes respectively, supporting previously reported associations.

BMC Musculoskelet Disord 2022; 23:774. [PMID: 35964023 PMCID: PMC9375337 DOI: 10.1186/s12891-022-05711-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Accepted: 07/27/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Successfully surgically treating degenerative disc diseases can be challenging to the spine surgeons, the long-term outcome relies on both the physical and mental status of the patient before and after treatment. Numerous studies underlined the role of inflammatory cytokines - like interleukin 1B and 6 - in the development of chronic diseases such as failed back surgery syndrome (FBSS) and major depressive disorder (MDD) which alter the outcome after spinal surgery. Our aim was to evaluate the associations of IL6 and IL1B gene polymorphisms with the long-term outcome of degenerative lumbar spine surgeries. METHODS An international genetical database (GENODISC) was combined with our institute's clinical database to create a large pool with long term follow up data. Altogether 431 patient's data were analysed. Patient reported outcome measures and surgical outcome was investigated in association with IL1B and IL6 SNPs with the help of 'SNPassoc' R genome wide association package. RESULTS Interleukin 1B variants analysis confirmed association with improvement of pain after surgery on individual SNP level and on haplotype level, moreover relationship with patient reported outcome and preoperative level of depression was found on individual SNP level. IL6 variants were associated with preoperative depression, somatization and with subsequent surgery. CONCLUSION Understanding the complexity of spinal surgery patients' long-term well-being is crucial in effectively treating chronic debilitating somatic diseases and the associated mental illnesses. Further studies should investigate more comprehensively the linkage of chronic physical and mental illnesses focusing on their simultaneous treatment.

BMC Cardiovasc Disord 2022; 22:229. [PMID: 35590253 PMCID: PMC9118748 DOI: 10.1186/s12872-022-02670-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 05/03/2022] [Indexed: 12/04/2022] Open
Abstract
Background To evaluate the relationship between IL-1α -889C/T (rs1800587), IL-1β -511C > T (rs16944), TNFα -308G > A (rs1800629), TNFα -238G > A (rs361525), IL-6 -174G > C (rs1800795), and IL-6 -572G > C (rs1800796) polymorphisms and the susceptibility to transposition of the great arteries (TGA). Methods A prospective analysis was performed on mothers whose newborns were diagnosed as having TGA. For each case of TGA, a mother who gave birth to a healthy neonate in the same period was randomly selected for the control group. The sample size was calculated before planning the study with 80% power and 5% alpha. Results Twenty-seven mothers whose newborn had TGA anomalies (group 1) and 27 mothers whose newborn had no TGA (group 2) were included in the study. There were no significant differences between the groups in terms of maternal age, pregestational body mass index, gestational age at birth and infant sex (p > 0.05). The genotype and allele distributions of IL-1α -889C/T (rs1800587), IL-1β -511C > T (rs16944), TNFα -308G > A (rs1800629), TNFα -238G > A (rs361525), IL-6 -174G > C (rs1800795) and IL-6 -572G > C (rs1800796) gene variants were not different between the two groups (p > 0.05). Conclusions There was no relation between IL-1α, IL-1β, IL-6, and TNFα promoter gene polymorphisms and TGA occurrence in our study group. Trial registration: This present prospective case–control study was conducted in Baskent University Hospital, Ankara, Turkey, between May 2020 and November 2021. Ethical approval was obtained from the university’s Clinical Research Ethics Commitee (No: KA20/211) in accordance with the Declaration of Helsinki.

Polymorphism of Interleukin-1 Gene Cluster in Polish Patients with Acute Coronary Syndrome. J Clin Med 2021; 10:jcm10050990.

Abstract
Background and objectives: Some experimental studies demonstrated adverse modulation of atherothrombosis by interleukin-1beta (IL-1b). To assess the relationship between the five most common variants of three polymorphisms of the IL1b gene cluster and the complexity of coronary atherosclerosis expressed in Gensini Score (GS), and the age of onset of the first acute coronary syndrome (ACS), we assessed the patients (pts) hospitalized due to ACS in this aspect. Materials and Methods: 250 individuals were included. The single nucleotide polymorphisms of IL1b gene: transition T/C at -31 position, C/T at -511, and those of IL1 receptor antagonist gene (IL1RN)—variable number of tandem repeats allele 1, 2, 3, or 4—were determined by PCR. GS was calculated from the coronary angiogram performed at the index ACS. The impact of the presence of T or C and allele 1 to 4 at the investigated loci on the mean GS, GS greater than 40, mean age of onset of ACS, and the fraction of pts over 60 years of age at ACS were compared between the five most common genotype variants. Results: The five most common variants were present in 203 pts (81.2%). Patients with pair 22 in ILRN had the lowest rate and those with pair 12 had the highest rate of ACS before 60 years of age (29.4 vs. 67.8%; p = 0.004). GS > 40 entailed an eight-fold increase of risk, as observed when pts with one T allele at locus -31 were compared with carriers of 2 or no T allele at this locus: OR 8.73 [CI95 4.26–70.99] p = 0.04. Conclusion: Interleukin-1 beta is subject to frequent genetic variability and our results show a potential relationship of this polymorphism with the extent of coronary atherosclerosis and age at the first ACS.

Abstract
Importance Although lipoprotein(a) (Lp[a]) is a causal genetic risk factor for atherosclerotic cardiovascular disease, it remains unclear which patients with established atherosclerotic cardiovascular disease stand to benefit the most from Lp(a) lowering. Whether inflammation can modulate Lp(a)-associated cardiovascular (CV) risk during secondary prevention is unknown. Objective To examine whether Lp(a)-associated CV risk is modulated by systemic inflammation in optimally treated patients at high risk of CV disease. Design, Setting, and Participants A prespecified secondary post hoc analysis of the double-blind, multicenter randomized clinical Assessment of Clinical Effects of Cholesteryl Ester Transfer Protein Inhibition With Evacetrapib in Patients at a High Risk for Vascular Outcomes (ACCELERATE) trial was conducted between October 1, 2012, and December 31, 2013; the study was terminated October 12, 2015. The study was conducted at 543 academic and community hospitals in 36 countries among 12 092 patients at high risk of CV disease (acute coronary syndrome, stroke, peripheral arterial disease, or type 2 diabetes with coronary artery disease) with measurable Lp(a) and high-sensitivity C-reactive protein (hsCRP) levels during treatment. Statistical analysis for this post hoc analysis was performed from September 26, 2018, to March 28, 2020. Interventions Participants received evacetrapib, 130 mg/d, or matching placebo. Main Outcomes and Measures The ACCELERATE trial found no significant benefit or harm of evacetrapib on 30-month major adverse cardiovascular events (CV death, myocardial infarction [MI], stroke, coronary revascularization, or hospitalization for unstable angina). This secondary analysis evaluated rates of CV death, MI, and stroke across levels of Lp(a). Results High-sensitivity C-reactive protein and Lp(a) levels were measured in 10 503 patients (8135 men; 8561 white; 10 134 received concurrent statins; mean [SD] age, 64.6 [9.4] years). In fully adjusted analyses, in patients with hsCRP of 2 mg/L or more but not less than 2 mg/L, increasing quintiles of Lp(a) were significantly associated with greater rates of death, MI, and stroke (P = .006 for interaction). Each unit increase in log Lp(a) levels was associated with a 13% increased risk of CV death, nonfatal MI, or stroke only in those with hsCRP levels of 2 mg/L or more (P = .008 for interaction). There was also a significant stepwise relationship between increasing Lp(a) quintiles and time to first CV death, MI, or stroke (log-rank P < .001) when hsCRP levels were 2 mg/L or more but not less than 2 mg/L. Sensitivity analyses in the ACCELERATE placebo-treated group yielded similar significant associations exclusively in the group with hsCRP of 2 mg/L or more. Conclusions and Relevance Elevated Lp(a) levels during treatment are related to CV death, MI, and stroke when hsCRP levels are 2 mg/L or more but not less than 2mg/L. This finding suggests a potential benefit of lowering Lp(a) in patients with residual systemic inflammation despite receipt of optimal medical therapy.

Abstract
Despite considerable progressions, cardiovascular disease (CVD) is still one of the major causes of mortality around the world, indicates an important and unmet clinical need. Recently, extensive studies have been performed on the role of inflammatory factors as either a major or surrogate factor in the pathophysiology of CVD. Epidemiological observations suggest the theory of the role of inflammatory mediators in the development of cardiovascular events. This may support the idea that targeted anti-inflammatory therapies, on the background of traditional validated medical therapies, can play a significant role in prevention and even reduction of cardiovascular disorders. Many randomized controlled trials have shown that drugs commonly useful for primary and secondary prevention of CVD have an anti-inflammatory mechanism. Further, many anti-inflammatory drugs are being examined because of their potential to reduce the risk of cardiovascular problems. In this study, we review the process of inflammation in the development of cardiovascular events, both in vivo and clinical evidence in immunotherapy for CVD.

Abstract
Background The participation of long noncoding RNAs (lncRNAs) in myocardial infarction has recently been noted. However, their underlying roles in the border zone of myocardial infarction remain unclear. This study uses microarrays to determine the profiles of lncRNAs and mRNAs in the border zone. Methods Bioinformatics methods were employed to uncover their underlying roles. Highly dysregulated lncRNAs was further validated via PCR. Results Four hundred seven lncRNAs and 752 mRNAs were upregulated, while 132 lncRNAs and 547 mRNAs were downregulated in the border zone of myocardial infarction. A circos graph was constructed to visualize the chromosomal distribution and classification of the dysregulated lncRNAs and mRNAs. The upregulated mRNAs in the border zone were most highly enriched in cytokine activity, binding, cytokine receptor binding and related processes, as ascertained through Go analysis. Pathway analysis of the upregulated mRNAs showed the most significant changes were in the TNF signaling pathway, cytokine–cytokine receptor interaction and chemokine signaling pathway and similar pathways and interactions. An lncRNA–mRNA co-expression network was established to probe into the underlying functions of the 10 most highly dysregulated lncRNAs based on their co-expressed mRNAs. In the co-expression network, we found 16 genes directly involved in myocardial infarction, including Alox5ap, Itgb2 and B4galt1. The lncRNAs AY212271, EF424788 and MRAK088538, among others, might be associated with myocardial infarction. BC166504 is probably a key lncRNA in the border zone of myocardial infarction. Conclusions The results may have revealed some aberrantly expressed lncRNAs and mRNAs that contribute to the underlying pathophysiological mechanisms of myocardial infarction.

Polymorphism of Interleukin 1B May Modulate the Risk of Ischemic Stroke in Polish Patients. ACTA ACUST UNITED AC 2019; 55:medicina55090558. [PMID: 31480765 PMCID: PMC6780056 DOI: 10.3390/medicina55090558] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2019] [Revised: 08/26/2019] [Accepted: 08/28/2019] [Indexed: 01/08/2023]
Abstract
Background and Objectives: Inflammation plays a crucial role in the pathophysiology of ischemic stroke (IS). Interleukin-1B and interleukin-1 receptor antagonists are key factors in inflammatory processes. Aims: The aims of our study were to evaluate the relationship between genetic variation in interleukin-1B (IL1B) rs1143627 and interleukin-1 receptor antagonist (IL1RN) variable-number-tandem-repeats (VNTR), and overall IS and subtype prevalence rates. Materials and Methods: The analysis included 147 hospitalized Polish patients with IS diagnosed using conventional criteria. The control group consisted of 119 healthy subjects. Genotypes were determined by polymerase chain reaction. Results: A significant association between rs1143627 and stroke was found. The -31C IL1B polymorphism showed an association with overall IS, OR = 2.30 (1.36-3.87) p = 0.020. An association was also detected for LVI (large vessel infarction) subtypes of stroke. After risk factor adjustment (age, diabetes mellitus, dyslipidemia), the C allele was found to be an independent risk factor for LVI, OR = 1.99 (1.05-3.79) p = 0.036. Significant association was not observed between IL1RN alleles and IS. Conclusions: Our results suggest that the C allele of IL1B rs1143627 may be associated with susceptibility to overall IS and LVI subtypes of stroke in the Polish population.

A polymorphism in the IL1B gene (rs16944 T/C) is associated with cutaneous leishmaniasis caused by Leishmania guyanensis and plasma cytokine interleukin receptor antagonist. Cytokine 2019; 123:154788.

Abstract
Nod-like Receptor Protein3 (NLRP3) inflammasome in macrophages infected with Leishmania sp. enhances the secretion of IL-1β. Excess IL-1β production is linked to disease severity in patients with cutaneous leishmaniasis (CL) caused by L. mexicana. Blockade of the NLRP3 inflammasome in cell cultures from skin biopsies of patients with CL caused by L. braziliensis inhibited the release of IL-1β. We hypothesized that common single nucleotide polymorphisms in the IL1B and in its receptor antagonist IL1RN genes may be predictive of CL caused by L. guyanensis. The SNPs -511T/C (rs16944) and +3954C/T (rs1143634) of the IL1B and IL1RN VNTR (rs2234663) were assessed in 881 patients with CL and 837 healthy controls by PCR-RFLP and direct PCR respectively. Plasma cytokines levels were also assayed. The plasma levels of IL-1β were higher in patients compared to control subjects. In contrast, increased plasma levels of IL-1Ra were observed in controls. The rs16944 C/C genotype was more common among the patients (OR = 1.5 [95%CI 1.1-2.0]; P = 0.004) and the C allele suggests susceptibility to CL (OR = 1.2 [95%CI 1.1-1.4]; P = 0.003). The rs16944 C/C genotype shows a tendency to correlate with lower levels of the IL-1Ra cytokine. Low levels of IL-1Ra cytokine and rs16944 C/C genotype seem to confer susceptibility to L. guyanensis-infection in the Amazonas.

Abstract
Interleukins play important roles in pregnancy. Altered expression and splicing of various interleukins have been linked to the pathophysiology of recurrent pregnancy loss. Polymorphisms in interleukin genes can affect the expression and/or splicing of their respective genes and thus influence the risk of recurrent pregnancy loss. In this work, we examined the association between the IL1B rs16944, IL1B rs1143634, IL6 rs1800795, IL6 rs1800796, IL10 rs1800896 and IL18 rs187238 polymorphisms and recurrent pregnancy loss risk in a Chinese population. Study subjects comprised 598 idiopathic recurrent pregnancy loss patients and 603 controls. The genotyping was accomplished by PCR-RFLP. Regression analysis was performed to evaluate the disease association. After adjustment by Bonferroni correction, only the IL1B rs16944 and IL6 rs1800796 polymorphisms were significantly associated with risk of recurrent pregnancy loss. The heterozygous TC genotype of IL1B rs16944 had an adjusted odds ratio (aOR) of 1.4209 (1.1302-1.8929) (P = 0.0019), while the homozygous CC genotype had an aOR of 1.7398 (1.2133-2.3203) (P = 0.0008). A significant association was also observed for the C allele [aOR = 1.3747 (1.1296-1.8972)] (P = 0.0003). For IL6 rs1800796, the heterozygous CG genotype, the homozygous GG genotype and the G allele had aORs of 0.7342 (0.4412-0.8423) (P = 0.0016), 0.5424 (0.1768-0.7865) (P = 0.0014) and 0.7009 (0.4511-0.8034) (P = 0.0007), respectively. In summary, the IL1B rs16944 and IL6 rs1800796 variants were associated with an increased and a decreased recurrent pregnancy loss risk, respectively.

Abstract
Accumulating research suggests that the pro-inflammatory cytokine interleukin-1β (IL-1β) has a modulatory effect on the hippocampus, a brain structure important for learning and memory as well as linked with both psychiatric and neurodegenerative disorders. Here, we used an imaging genetics strategy to test an association between an IL-1β polygenic score and hippocampal volume in two independent samples. Our polygenic score was derived using summary statistics from a recent genome-wide association study of circulating cytokines that included IL-1β (N = 3,309). In the first sample of 512 non-Hispanic Caucasian university students (274 women, mean age 19.78 ± 1.24 years) from the Duke Neurogenetics Study, we identified a significant positive correlation between IL-1β polygenic scores and hippocampal volume. This positive association was successfully replicated in a second sample of 7,960 white British volunteers (4,158 women, mean age 62.63 ± 7.45 years) from the UK Biobank. Our results lend further support in humans, to the link between IL-1β and the structure of the hippocampus.

Abstract
Objective: Cytokines play an important role in the pathogenesis of type 2 diabetes (T2DM) and its complications. The aim of the study was to evaluate an association of the -511 (C/T) polymorphism in the IL1B gene with diabetic nephropathy (DN). Methods: The study population included 860 patients with T2DM (506 with diabetic nephropathy and 354 without nephropathy) as well as 505 healthy individuals. Genomic DNA was genotyped for the IL1B -511 (C/T) polymorphism using PCR-RFLP technique. Results: The IL1B -511 C/T polymorphism was genotyped in 860 T2DM patients with or without DN and 505 healthy individuals. The average age of patients was 65.3 years in DN+ and 62.2 years in DN- subgroups. The genotype distribution did not differ significantly between patients and controls. Only a tendency to a slight increase of T allele frequency was observed in patient group. Genotype and allele frequencies of -511 C/T polymorphism were compared in patients with DN and those without it. The minor allele (T) and homozygote TT frequencies were significantly different between subgroups. The T allele was more frequent in DN+ patients, with odds ratio 1.45 (95% CI 1.2-1.8), p = 0.0003. The TT genotype frequency was also higher in DN+, with OR 1.76 (96% CI 1.1-2.7), p = 0.01. Conclusion: In a studied population the -511 C/T polymorphism in the IL1B gene is associated with diabetic nephropathy in dialyzed T2DM patients. Further studies are required to confirm the clinical significance of this finding.

Acupuncture treatment is associated with a decreased risk of developing stroke in patients with depression: A propensity-score matched cohort study. J Affect Disord 2019; 250:298-306.

Abstract
BACKGROUND Depression had a significantly increased risk of stroke. Some patients with depression seek acupuncture treatment. The aim of this study is to investigate the association between acupuncture treatment and risk of developing stroke in patients with depression. METHODS Patients with newly diagnosed depression above 18 years old between 1997 and 2010 were selected from the Taiwanese National Health Insurance Research Database, and followed up until the end of 2013. The 1:1 propensity score method was used to match an equal number of patients (N = 13,823) in the acupuncture and non-acupuncture cohorts, based on characteristics including sex, age, baseline comorbidity and drug used. The outcome measurement was the comparison of stroke incidence in the two cohorts. We used the Cox regression model and the Kaplan-Meier method to estimate the risk of developing stroke. RESULTS Compared with the non-acupuncture cohort, patients who received acupuncture treatment had a lower risk of stroke (adjusted hazard ratio (HR) = 0.49, 95% confidential interval = 0.45-0.52) after adjustment for age, sex, comorbidities and drugs used. Regarding the two types of stroke, acupuncture users also had lower risk of hemorrhagic or ischemic stroke (adjusted HR = 0.37 and 0.49, respectively). The cumulative incidence of stroke in the acupuncture cohort was significantly lower than that of the non-acupuncture cohort (log-rank test, p < 0.001). At the 5th year of follow-up, 7.22% of acupuncture users had stroke onset compared with 14% in the non-acupuncture cohort. LIMITATIONS The database provided information of antidepressants but not the severity of depression. Details of the life style and selection of acupoints were also not provided. CONCLUSIONS The present study revealed that acupuncture reduced the risk of developing stroke in depression patients in Taiwan. Further clinical studies investigating the mechanisms and efficacy of acupuncture are warranted.

Activation of Interleukin-1 Beta in Arterialized Vein Grafts and the Influence of the -511C/T IL-1β Gene Polymorphism. J Cardiovasc Dev Dis 2019; 6:jcdd6020020. [PMID: 31052244 PMCID: PMC6616868 DOI: 10.3390/jcdd6020020] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2019] [Revised: 04/23/2019] [Accepted: 04/28/2019] [Indexed: 11/17/2022] Open
Abstract
The interleukin-1 family is associated with innate immunity and inflammation. The latter has been linked to the genesis of cardiovascular diseases. We, therefore, investigated whether interleukin-1 beta (IL-1β) is activated during arterialization of vein grafts. First, we examined the activation of IL-1β using the rat arterialized jugular vein serially sampled for up to 90 days. IL-1β expression increased 18 times on day 1 in the arterialized rat jugular vein and remained five times above nonarterialized vein levels for up to 90 days. Similarly, IL-1β expression increased early (1-5 days) in human vein graft autopsy samples compared with late phases (1-4 years). Activation was also detected in ex vivo arterialized human saphenous veins. Upon stratification of the results, we uncovered a T allele promoter attenuating effect in IL-1β activation in response to hemodynamic stress. Altogether, the results show that IL-1β is activated during arterialization of vein grafts in rats and humans, and this response is modulated by -511C/T IL-1β gene polymorphism. It is tempting to speculate that the activation of IL-1β, and consequently local inflammation, modulates early vascular remodeling and that the gene polymorphism may be useful in predicting outcomes or assisting in interventions.

Abstract
Pro-inflammatory cytokines, such as interleukin (IL)-6 and tumor necrosis factor-α (TNF-α), are thought to play a fundamental role in the pathogenesis of depression within a subset of individuals. However, the involvement of IL-1β has not been as consistently linked to depression, possibly owing to difficulties in detecting this cytokine in blood samples or that changes in circulating levels might only be apparent in a subgroup of patients who have experienced early-life adversity. From this perspective, the association between early-life adversity and depressive illness might depend on genetic variants regulating IL-1β activity. Considering the inflammatory-depression link, and that women are twice as likely to experience depression compared to men, the current study (N = 475 university students) examined the moderating role of three independent cytokine single nucleotide polymorphisms (SNPs; IL-1β rs16944, IL-6 rs1800795 SNP, TNF-α rs1800629) in the relationship between early-life adversity and depressive symptoms, and whether these relations differed between males and females. The relation between childhood adversity and depressive symptoms was moderated by the IL-1β SNP, and further varied according to sex. Specifically, among females, higher childhood maltreatment was accompanied by elevated depressive symptoms irrespective of the IL-1β SNP, but among males, this relationship was particularly pronounced for those carrying the GG genotype of the IL-1β SNP. These findings suggest that, in the context of early life adversity, genetic variations of IL-1β functioning are related to depressive symptomatology and this may vary among males and females. The present study also, more broadly, highlights the importance of considering the confluence of experiential factors (e.g., early life adversity) and personal characteristics (e.g., sex and genetics) in understanding depressive disorders, an approach increasingly recognized in developing personalized treatment approaches to this illness.

Abstract
Abstract The aim of this study was to investigate the association of five polymorphisms in the IL1A and IL1B genes in Brazilian patients with primary open angle glaucoma (POAG). A case–control study, including 214 unrelated POAG patients and 187 healthy individuals, was conducted to evaluate the frequency of polymorphisms in the IL1A and IL1B genes. Ophthalmic evaluation was performed and genomic DNA was obtained from all participants. Five single nucleotide polymorphisms (SNPs): IL1A (–889C/T: rs1800587:C > T, +4845G/T:rs17561G>T) and IL1B (–31C/T:rs1143627:T > C, –511C/T:rs16944C>T and +3954C/T:rs1143634:C > T) were genotyped through direct sequencing. The association of individual SNPs was tested using logistic regression. There was an association between the –31C/T and –511 C/T polymorphisms in the IL1B gene with POAG (p = 0.002 and p = 0.009, respectively). High linkage disequilibrium was observed between the –31C/T and –511C/T polymorphisms. The statistical analysis showed that the T/C haplotype (–31/–511) in the IL1B gene is more frequent in controls (p = 0.011) and the C/T haplotype (–31/–511) is more common in POAG patients (p = 0.018). Among POAG cases, the genotypic distribution of the –31C/T and –511 C/T SNPs was significantly different in patients who underwent anti-glaucomatous surgery compared to patients without surgery (p = 0.016 and 0.023, respectively). There was no statistically significant difference for the remaining SNPs between POAG patients and controls. In conclusion, the C allele of the –31C/T and the T allele of the –511C/T polymorphisms in the IL1B gene may represent a “risk haplotype” for the development of POAG in Brazilian individuals. Further studies with larger cohorts of patients are necessary to substantiate these findings.

Abstract
Sofosbuvir (SOF) and daclatasvir combination with or without ribavirin proved to be effective and safe in the treatment of hepatitis C virus infection. The study aimed to assess the efficacy of (SOF plus daclatasvir) combination + ribavirin in the treatment of treatment-experienced HCV genotype 4 Egyptian patients and to investigate the impact of IL-1β _31, IL-1β _511, and IL-1RN and T29C of ESR1 genes polymorphisms on treatment outcome. The study also aimed to assess the effect of the treatment on liver fibrosis. The sustained virologic response was assessed at 0, 4, 12, and 24 weeks from the beginning of treatment by RT-PCR. IL-1β _31, IL-1β _511, IL-1RN, and T29C genes polymorphisms were examined by PCR-based techniques in two groups of patients (responders and non-responders) and a control group of healthy subjects. A significant association between IL-1β_511 gene polymorphism and SOF/DAV-induced response was observed, where the "CC" genotype was the most frequent in responders while the "CT" genotype was the most frequent among non-responders (P = 0.0001, OR = 39; 95% CI = 4.7-316). IL-1RN gene polymorphism also showed significant associations with response to treatment, genotypes that include allele "1" were the most frequent in responders, particularly the homozygous genotype "1/1" (P = 0.0001, OR = 2.3; 95% CI = 1.57-3.2). However, the genotypes "4/4" and "2/4" were the most frequent in non-responders; (P = 0.0001). At least 71% of the responders carry allele "1" while 54% of non-responders were allele "4" carriers (P value = 0.0001. OR = 2.8; 95% CI = 6.4-134.2). Liver fibrosis is significantly improved regardless of the response. © 2018 IUBMB Life, 70(11):1156-1163, 2018.

Abstract
BACKGROUND Many studies have reported that the IL-1β + 3954C/T polymorphism (rs1143634) is related to myocardial infarction (MI). To classify the association between IL-1β + 3954C/T and MI susceptibility, we performed a meta-analysis. METHODS We retrieved relevant literature from electronic databases (Embase, PubMed, Cochrane, and Web of Science). Pooled odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated with a fixed effect model or a random effect model. Sensitivity analysis and publication bias results are also presented. RESULTS Nine eligible studies (2299 controls and 2203 cases) were included. The pooled results showed a significant relationship between MI and IL-1β + 3954C/T in an allelic comparison (T vs C: OR = 1.13, 95% CI 1.02-1.25, I = 0%, PH = .448) and in a dominant model (TC + TT vs CC: OR = 1.15, 95% CI 1.02-1.30, I = 0%, PH = .880). Ethnic subgroup analysis showed similar results in Caucasian populations: an allelic comparison (T vs C: OR = 1.16, 95% CI 1.04-1.29, I = 0%, PH = .701), homozygote model (TT vs CC: OR = 1.36, 95% CI 1.04-1.79, I = 0%, PH = .673), and dominant model (TC + TT vs CC: OR = 1.17, 95% CI 1.02-1.33, I = 0%, PH = .851). In addition, similar effects remained in subgroups analyses of high-quality studies and PCR-RFLP (restriction fragment length polymorphism) data. CONCLUSION Our meta-analysis proved that IL-1β + 3954C/T is associated with MI susceptibility, especially among Caucasian populations.

Abstract
Interleukin-1β (IL-1β) assumes a centric role in the regulation of immune and inflammatory responses and thus has been recognized in immune mediated diseases like type 2 diabetes mellitus (T2DM). We aimed to investigate expressed level of IL-1β and its relation with IL-1β -511T>C polymorphism in T2DM patients. This study enrolled 80 subjects (50 patients with T2DM and 30 healthy control subjects). Laboratory investigations included fasting (FBG) and 2 h postprandial blood sugar (2 h PBG), HBA1c, lipid profile, and renal function tests. Genotyping of IL-1β -511T>C (rs16944) SNP assay by real-time PCR and relative quantitation of IL-1β gene expression transcript by real-time PCR. RESULTS T2DM patients had significantly higher FBG and 2 h PBG, HBA1c, LDLc, TC, TG, systolic, and diastolic BP while lower HDLc compared with control group. IL 1- β -511 T>C, CC genotype and C allele were significantly associated with risk of T2DM with odds ratio (OR) 4.73, 95%CI (1.21-18.39) and OR 2.27, 95%CI (1.72-4.40), respectively. Moreover, diabetic patients had significantly higher IL 1- β gene transcript compared with control group (P < 0.001). CC genotype of IL 1- β -511 T > C had the highest significant level of IL 1- β gene transcript demonstrated compared with C/T and T/T genotypes (P < 0.001) in patients. CONCLUSION C allele of IL-1 β -511 T >C could be considered risk factor contributor to T2DM and excess level of IL-1 β transcript may disclose to some degree the inflammatory role of cytokines in T2DM.

Abstract
Introduction: Cardiovascular and neurodegenerative disorders are among the major causes of mortality in the developed countries. Population studies evaluate the genetic risk, i.e. the probability of an individual carrying a specific disease-associated polymorphism. Identification of risk polymorphisms is essential for an accurate diagnosis or prognosis of a number of pathologies. Aims: The aim of this study was to characterize the influence of risk polymorphisms associated with lipid metabolism, hypertension, thrombosis, and dementia, in a large population of Spanish individuals affected by a variety of brain and vascular disorders as well as metabolic syndrome. Material & Method: We performed a cross-sectional study on 4415 individuals from a widespread regional distribution in Spain (48.15% males and 51.85% females), with mental, neurodegenerative, cerebrovascular, and metabolic disorders. We evaluated polymorphisms in 20 genes involved in obesity, vascular and cardiovascular risk, and dementia in our population and compared it with representative Spanish and European populations. Risk polymorphisms in ACE, AGT(235), IL6(573), PSEN1, and APOE (specially the APOE-ε4 allele) are representative of our population as compared to the reference data of Spanish and European individuals. Conclusion: The significantly higher distribution of risk polymorphisms in PSEN1 and APOE-ε4 is characteristic of a representative number of patients with Alzheimer’s disease; whereas polymorphisms in ACE, AGT(235), and IL6(573), are most probably related with the high number of patients with metabolic syndrome or cerebrovascular damage.

Abstract
INTRODUCTION The study of variations in genes involved in the different events that trigger the atherogenic process, such as lipid metabolism (modification of LDL-cholesterol), endothelial function and hypertension, immune response (recruitment of macrophages and foam cell formation) and stability of atherosclerotic plaques (thrombosis), established the risk for suffering a vascular disorder. A total of 2455 cases over 50 years of age were genotyped for a panel of 19 SNPs in 15 genes encoding for proteins involved in the atherogenic process. This study shows the relevance of polymorphisms in APOB (odds ratio (OR), 1.17; 95% confidence interval (95% CI), 0.74-1.85), APOC3 (OR, 1.33; 95% CI, 0.82-2.17) and APOE (OR, 1.75; 95% CI, 1.09-2.80), as genetic risk markers for hypercholesterolemia; polymorphisms in ACE (OR, 1.68; 95% CI, 0.32-8.77) and AGT (OR, 1.74; 95% CI, 0.97-3.14) for hypertension; and in APOE*3/*4 (OR, 2.06; 95% CI, 1.70-2.51) and APOE*4/*4 (OR, 3.08; 95% CI, 1.85-5.12) as unambiguous markers of dementia. RESULT Our results also showed the transversal importance of proinflammatory cytokines in different stages of atherogenesis, with special relevance of IL6 (OR, 1.39; 95% CI, 0.56-3.49) and TNF (OR, 1.40; 95% CI, 0.92-2.15) related to hypercholesterolemia and hypertension. The set of markers involved in this genetic risk panel makes it a powerful tool in the management of patients with different vascular disorders.

Abstract
This study aimed to identify the key differentially expressed genes (DEGs) following ischemic stroke (IS).The GSE22255 microarray dataset, which contains samples from peripheral blood mononuclear cells of 20 IS patients and 20 sex- and age-matched controls, was downloaded from the Gene Expression Omnibus. After data pre-processing, DEGs were identified using the Linear Models for Microarray Data package in R. The Search Tool for the Retrieval of Interacting Genes database was used to predict the interactions among the products of DEGs, and then Cytoscape software was used to visualize the protein-protein interaction (PPI) network. DEGs in the PPI network were then analyzed using the Database for Annotation, Visualization, and Integrated Discovery online software to predict their underlying functions through functional and pathway enrichment analyses.A total of 144 DEGs were identified in IS samples compared with control samples, including 75 upregulated and 69 downregulated genes. Genes with higher degrees in the PPI network included FOS (degree = 26), TP53 (degree = 22), JUN (degree = 20), EGR1 (degree = 18), JUNB (degree = 16), and ATF3 (degree = 15), and these genes may function in IS by interacting with each other (e.g., EGR1-JUN, EGR1-TP53, ATF3-FOS, and JUNB-FOS). Functional enrichment analysis indicated that the downregulated TP53 gene was enriched in immune response and protein targeting categories.ATF3 and EGR1 may have an important protective effect on IS, whereas FOS, JUN, and JUNB may be associated with the development of IS. In addition, TP53 may function as an indicator of poor prognosis for IS through its association with the immune response and protein targeting.

Abstract
Interleukins (ILs) are the most typical inflammatory and immunoregulatory cytokines. Evidences have shown that polymorphisms in ILs are associated with cerebral infarction risk. However, the results remain inconclusive. The present study was to evaluate the role of ILs polymorphisms in cerebral infarction susceptibility. Relevant case-control studies published between January 2000 and December 2015 were searched and retrieved from the electronic databases of Web of Science, PubMed, Embase and the Chinese Biomedical Database. The odds ratio (OR) with its 95% confidence interval (CI) were employed to calculate the strength of association. A total of 55 articles including 12619 cerebral infarction patients and 14436 controls were screened out. Four ILs (IL-1, IL-6, IL-10 and IL-18) contained nine single nucleotide polymorphisms (SNPs; IL-1α -899C/T, IL-1β -511C/T and IL-1β +3953C/T; IL-6 -174G/C and -572C/G; IL-10 -819C/T and -1082A/G; IL-18 -607C/A and -137G/C). Our result showed that IL-1α -899C/T and IL-18 -607C/A (under all the genetic models), and IL-6 -572C/G (under the allelic model, heterogeneity model and dominant model) were associated with increased the risk of cerebral infarction (P<0.05). Subgroup analysis by ethnicity showed that IL-6 -174G/C polymorphism (under all the five models) and IL-10 -1082A/G polymorphism (under the allelic model and heterologous model) were significantly associated with increased the cerebral infarction risk in Asians. Other genetic polymorphisms were not related with cerebral infarction susceptibility under any genetic models. In conclusion, IL-1α -899C/T, IL-6 -572C/G and IL-18 -607C/A might be risk factors for cerebral infarction development. Further studies with well-designed and large sample size are still required.

Abstract
BACKGROUND The reason for the difference in susceptibility to red blood cell (RBC) alloimmunization among patients with sickle cell disease (SCD) is not clearly understood and is probably the result of multiple factors. Our hypothesis is that genetic polymorphisms are associated with RBC alloimmunization. STUDY DESIGN AND METHODS We investigated the possible association of susceptibility to RBC alloimmunization with polymorphisms of HLA and cytokines genes in 161 SCD patients prior exposed to RBC transfusion. Cytokine gene polymorphisms were analyzed by polymerase chain reaction (PCR) and TaqMan assays. HLA Class I genotyping was performed using PCR-specific sequence of oligonucleotides. Polymorphism frequencies were compared using the Fisher's exact test. RESULTS Our results revealed increased percentage of the A allele and the GA genotype of the TNFA -308G/A cytokine among alloimmunized patients when compared to nonalloimmunized patients (A allele, 16.4% vs. 6.8%, p = 0.004; GA genotype, 32.8% vs. 11.7%, p = 0.0021). In addition, the IL1B -511T allele and the IL1B -511TT and CT genotype frequencies were overrepresented among alloimmunized patients (T allele, 53.0% vs. 37.5%, p = 0.0085; CT + TT genotypes, 81.82% vs. 60.87%, p = 0.0071). In relation to HLA Class I, we found a higher frequency of HLA-DRB1*15 among patients alloimmunized to Rh antigens when compared to nonalloimmunized patients (15.63% vs. 6.98%, p = 0.044). CONCLUSION Brazilian SCD patients with the TNFA, IL1B, and HLA-DRB1 gene polymorphisms were at increased risk of becoming alloimmunized by RBC transfusions. These findings may contribute to the development of future therapeutic strategies for patients with SCD with higher susceptibility of alloimmunization.

Abstract
OBJECTIVE Current evidence suggests that many GWAS and IL1 SNPs are associated with periodontal diseases but their functional role remains ambiguous. Therefore, it is imperative to elucidate the molecular pathways through which these SNPs might act on the development of the disease. The purpose of this review was to highlight the regulatory elements of noncoding regions of the genome and provide insights on the functional role of periodontitis-associated GWAS and IL1 SNPs. DESIGN A search was performed using ENCODE data available on different browsers. RESULTS GWAS and IL1 SNPs overlap DNase I hypersensitivity sites, histone modifications and transcription binding sites. Some of these noncoding variants influenced the transcription activity of inflammatory genes. CONCLUSION SNPs associated with periodontal diseases may contribute to the development of the disorder through their functional roles. Unraveling the character of genetic components might explain the diversity of clinical phenotypes among population groups as well as disease susceptibility.

Abstract
Background
Various complications lead to reoperation in patients who undergo prosthetic valve replacement where inflammatory process could be involved. The goals of this study were to identify risk factors that correlate with reoperation in patients with prosthetic heart valves and to investigate the relationship between reoperation and inflammatory gene polymorphisms. Results
The study included 228 patients from the EwhA–Severance Treatment Group of Warfarin. Single nucleotide polymorphisms of c-reactive protein (CRP), interferon-gamma, interleukin 1 beta, interleukin 6, interleukin 10, transforming growth factor beta 1, and tumor necrosis factor genes were genotyped by means of SNaPshot and TaqMan assays. Thirty-nine patients (17.1 %) underwent more than one heart valve operation. A threefold increased risk for heart valve reoperation was evident in homozygous variant-type (TT) carriers as compared with ancestral allele carriers of CRP rs1205. Logistic regression analysis revealed that CRP rs1205 (OR 2.68, 95 % CI 1.22–5.90, p = 0.014), valve position (mitral valve OR 2.80, 95 % CI 1.01–7.80, p = 0.048; tricuspid valve OR 9.24, 95 % CI 2.46–34.70, p = 0.001; reference: aortic valve) and time after first operation (OR 1.13, 95 % CI 1.06–1.20, p < 0.001) affected the risk of reoperation. Conclusions Inflammatory gene polymorphisms could be a possible marker of risk for reoperation in patients with prosthetic heart valve surgery.

Abstract
Vascular diseases are usually caused by multifactorial pathogeneses involving genetic and environmental factors. Our current understanding of vascular disease is, however, based on the focused genotype/phenotype studies driven by the “one-gene/one-phenotype” hypothesis. Drugs with “pure target” at individual molecules involved in the pathophysiological pathways are the mainstream of current clinical treatments and the basis of combination therapy of vascular diseases. Recently, the combination of genomics, proteomics, and metabolomics has unraveled the etiology and pathophysiology of vascular disease in a big-data fashion and also revealed unmatched relationships between the omic variability and the much narrower definition of various clinical phenotypes of vascular disease in individual patients. Here, we introduce the phenomics strategy that will change the conventional focused phenotype/genotype/genome study to a new systematic phenome/genome/proteome approach to the understanding of pathophysiology and combination therapy of vascular disease. A phenome is the sum total of an organism’s phenotypic traits that signify the expression of genome and specific environmental influence. Phenomics is the study of phenome to quantitatively correlate complex traits to variability not only in genome, but also in transcriptome, proteome, metabolome, interactome, and environmental factors by exploring the systems biology that links the genomic and phenomic spaces. The application of phenomics and the phenome-wide associated study (PheWAS) will not only identify a systemically-integrated set of biomarkers for diagnosis and prognosis of vascular disease but also provide novel treatment targets for combination therapy and thus make a revolutionary paradigm shift in the clinical treatment of these devastating diseases.

Influence of cytokine and cytokine receptor gene polymorphisms on the degree of liver damage in patients with chronic hepatitis C. Meta Gene 2016; 9:90-6. [PMID: 27200267 PMCID: PMC4864212 DOI: 10.1016/j.mgene.2016.04.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2016] [Revised: 04/05/2016] [Accepted: 04/20/2016] [Indexed: 01/06/2023] Open
Abstract
Hepatic fibrosis may be the result of repetitive injury to hepatocytes caused by HCV infection and the immune response to it. Cytokines regulate the inflammatory response to injury and modulate hepatic fibrogenesis. Single nucleotide polymorphisms (SNPs) located in cytokine genes may influence the cytokine expression and secretion that may contribute to hepatic fibrogenesis in HCV infection. The aim of this study was to determine the genotype of 22 SNPs found in the genes of 13 cytokines/cytokine receptors to assess the influence of polymorphic variants on the stage of liver damage in Brazilian patients chronically infected with HCV genotype 1 only. 141 unrelated patients were grouped according to their stage of fibrosis: absence of fibrosis or patients in the initial stages of fibrosis (F0-F2, n = 84), patients with advanced stages of fibrosis or cirrhosis (F3-F4, n = 57), without cirrhosis (F0-F3, n = 103), and with cirrhosis (F4, n = 38). The comparison of frequencies in each sub-sample was performed by 2 × 2 contingency tables using the chi-square or Fisher's exact test. Stepwise logistic regression was also used to assess independent associations between cirrhosis or fibrosis with polymorphic variants. The TNFA-308G:A genotype conferred increased risk of fibrosis and cirrhosis. The TNFA-238G:G genotype was associated with protection from cirrhosis. The IL10-819C:T genotype conferred protection from fibrosis and the IL1B-511C:T genotype conferred increased risk of cirrhosis. Some of these genotypes showed results on the borderline of statistical significance in the bivariate analysis. We conclude that gene variants of cytokines/receptors may influence liver damage in patients chronically infected by HCV genotype 1.

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.

Interleukin-1β gene variants are associated with QTc interval prolongation following cardiac surgery: a prospective observational study. Can J Anaesth 2016; 63:397-410. [PMID: 26858093 DOI: 10.1007/s12630-015-0576-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2015] [Revised: 10/13/2015] [Accepted: 12/21/2015] [Indexed: 01/10/2023] Open
Abstract
BACKGROUND We characterized cardiac surgery-induced dynamic changes of the corrected QT (QTc) interval and tested the hypothesis that genetic factors are associated with perioperative QTc prolongation independent of clinical and procedural factors. METHODS All study subjects were ascertained from a prospective study of patients who underwent elective cardiac surgery during August 1999 to April 2002. We defined a prolonged QTc interval as > 440 msec, measured from 24-hr pre- and postoperative 12-lead electrocardiograms. The association of 37 single nucleotide polymorphisms (SNPs) in 21 candidate genes -involved in modulating arrhythmia susceptibility pathways with postoperative QTc changes- was investigated in a two-stage design with a stage I cohort (n = 497) nested within a stage II cohort (n = 957). Empirical P values (Pemp) were obtained by permutation tests with 10,000 repeats. RESULTS After adjusting for clinical and procedural risk factors, we selected four SNPs (P value range, 0.03-0.1) in stage I, which we then tested in the stage II cohort. Two functional SNPs in the pro-inflammatory cytokine interleukin-1β (IL1β), rs1143633 (odds ratio [OR], 0.71; 95% confidence interval [CI], 0.53 to 0.95; Pemp = 0.02) and rs16944 (OR, 1.31; 95% CI, 1.01 to 1.70; Pemp = 0.04), remained independent predictors of postoperative QTc prolongation. The ability of a clinico-genetic model incorporating the two IL1B polymorphisms to classify patients at risk for developing prolonged postoperative QTc was superior to a clinical model alone, with a net reclassification improvement of 0.308 (P = 0.0003) and an integrated discrimination improvement of 0.02 (P = 0.000024). CONCLUSION The results suggest a contribution of IL1β in modulating susceptibility to postoperative QTc prolongation after cardiac surgery.

Abstract
Background and Purpose—
Tissue factor (TF) expression is increased in inflammatory atherosclerotic plaques and has been related to their thrombogenicity. Blood-borne TF has been also demonstrated to contribute to thrombogenesis. However, few studies have evaluated the association of circulating levels of TF with stroke. We investigated the association of baseline circulating levels of TF with stroke events occurred in the European Prospective Investigation into Cancer and Nutrition-Italy cohort.
Methods—
Using a nested case–cohort design, a center-stratified random sample of 839 subjects (66% women; age range, 35–71 years) was selected as subcohort and compared with 292 strokes in a mean follow-up of 9 years. Blood samples were collected at baseline in citrate, plasma was stored in liquid nitrogen and TF was measured by ELISA (IMUBIND, TF ELISA, Instrumentation Laboratory, Milan, Italy). The odd ratios and 95% confidence intervals, adjusted by relevant confounders (covariates of TF) and stratified by center, were estimated by a Cox regression model using Prentice method.
Results—
Individuals in the highest compared with the lowest quartile of TF plasma levels had significantly increased risk of stroke (odds ratio
IVvsI quartile
, 2.01; 95% confidence interval, 1.25–3.23). The association was independent from several potential confounders (odds ratio
IVvsI quartile
, 1.91; 95% confidence interval, 1.15–3.19). No differences were observed between men and women. The increase in risk was restricted to ischemic strokes (odds ratio
IVvsI quartile
, 2.13; 95% confidence interval, 1.10–4.12; fully adjusted model), whereas high levels of TF were not associated with the risk of hemorrhagic stroke (odds ratio
IVvsI quartile
, 1.12; 95% confidence interval, 0.49–2.55; fully adjusted model).
Conclusions—
Our data provide evidence that elevated levels of circulating TF are potential risk factors for ischemic strokes.

Abstract
AIM The association between Interleukin-1 (IL-1) gene polymorphism and stroke remains controversial. The present study was designed to clarify this relationship through a pooled analysis of the numerous epidemiological studies focusing on this association. METHODS Published data addressing the association between polymorphism of the IL-1 gene and stroke were selected from electronic databases. A total of 21 studies from 19 publications including 5280 stroke patients and 5699 controls were included in this meta-analysis which detect whether IL-1α-889C/T, IL-1β-511C/T and IL-1 RN polymorphism were associated with stroke susceptibility. RESULT The combined results of overall analysis revealed that there was a significant association between IL-1α-889C/T polymorphism and stroke (allele model: OR = 1.39, 95% CI = 1.14-1.68, P < 0.001; recessive model: OR = 1.56, 95% CI = 1.27-1.90, P < 0.001; dominant model: OR = 1.45, 95% CI = 1.13-1.87, P = 0.004; additive model: OR = 1.70, 95% CI = 1.37-2.10, P < 0.001). On a subgroup analysis by ethnicity of study population, significant association was found in Asians (allele model: OR = 1.25 95% CI = 1.12-1.39, P < 0.001; recessive model: OR = 1.36, 95% CI = 1.09-1.69, P = 0.007; dominant model: OR = 1.29, 95% CI = 1.12-1.48, P < 0.001; additive model: OR = 1.42, 95% CI = 1.13-1.80, P = 0.003). There are no associations of IL-1β-511C/T and IL-RN polymorphisms on stroke risk were identified. CONCLUSION In conclusion, our results suggested that IL-1α-889C/T polymorphism is associated with stroke risk, especially in Asians. However, no associations of IL-1β-511C/T and IL-RN polymorphisms on stroke risk in overall analysis or subgroup analysis.

Abstract
Dental care costs in the United States exceed $100 billion annually. Personalized medicine efforts in dentistry are driven by potentially compelling clinical utility and cost-effectiveness prospects in the major diseases of periodontitis, caries, and oral cancers. This review discusses progress and challenges identifying genetic markers and showing clinical utility in dentistry. Genome-wide association studies (GWAS) of chronic periodontitis (CP) identified no significant variants, but CDKN2BAS variants on chromosome 9 were significantly associated with aggressive periodontitis. Stratifying patients by interleukin (IL)-1 gene variants, smoking and diabetes differentiated CP prevention outcomes. Dental caries' GWAS identified significant signals in LYZL2, AJAp1, and KPNA4; and efforts are ongoing to identify genetic factors for multiple caries phenotypes. Trials of molecularly targeted therapies are in progress for oral, head, and neck squamous cell carcinomas (OHNSCC) and results have been promising but limited in their effectiveness. Current opportunities and challenges for molecular targeting for OHNSCC are discussed.

Abstract
OBJECTIVES The aim of this study was to assess the influence of pro-inflammatory interleukin (IL)-1 genotype status on the risk for coronary artery disease (CAD), defined as >50% diameter stenosis, and cardiovascular events mediated by oxidized phospholipids (OxPLs) and lipoprotein (Lp) (a). BACKGROUND OxPLs are pro-inflammatory, circulate on Lp(a), and mediate CAD. Genetic variations in the IL-1 region are associated with increased inflammatory mediators. METHODS IL-1 genotypes, OxPL on apolipoprotein B-100 (OxPL/apoB), and Lp(a) levels were measured in 499 patients undergoing coronary angiography. The composite genotype termed IL-1(+) was defined by 3 single-nucleotide polymorphisms in the IL-1 gene cluster associated with higher levels of pro-inflammatory cytokines. All other IL-1 genotypes were termed IL-1(-). RESULTS Among IL-1(+) patients, the highest quartile of OxPL/apoB was significantly associated with a higher risk for CAD compared with the lowest quartile (odds ratio [OR]: 2.84; p = 0.001). This effect was accentuated in patients age ≤60 years (OR: 7.03; p < 0.001). In IL-1(-) patients, OxPL/apoB levels showed no association with CAD. The interaction was significant for OxPL/apoB (OR: 1.99; p = 0.004) and Lp(a) (OR: 1.96; p < 0.001) in the IL-1(+) group versus the IL-1(-) group in patients age ≤60 years but not in those age >60 years. In IL-1(+) patients age ≤60 years, after adjustment for established risk factors, high-sensitivity C-reactive protein, and Lp(a), OxPL/apoB remained an independent predictor of CAD. IL-1(+) patients above the median OxPL/apoB presented to the cardiac catheterization laboratory a mean of 3.9 years earlier (p = 0.002) and had worse 4-year event-free survival (death, myocardial infarction, stroke, and need for revascularization) compared with other groups (p = 0.006). CONCLUSIONS Our study suggests that IL-1 genotype status can stratify population risk for CAD and cardiovascular events mediated by OxPL. These data suggest a clinically relevant biological link between pro-inflammatory IL-1 genotype, oxidation of phospholipids, Lp(a), and genetic predisposition to CAD and cardiovascular events.

Abstract
BACKGROUND Interleukin-6 (IL-6) plays a critical role in the development and progression of cardiovascular disease. Emerging evidence suggests that two common polymorphisms (-174 G/C and -572 G/C) in the IL-6 gene might have an impact on an individual's susceptibility to myocardial infarction (MI), but individually published results are inconclusive. This meta-analysis aimed to derive a more precise estimation of the relationship between IL-6 -174 G/C and -572 G/C polymorphisms and MI risk. METHOD An extensive literary search for relevant studies was conducted in PubMed, Embase, Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, China BioMedicine (CBM), and China National Knowledge Infrastructure (CNKI) databases from their inception through August 1st, 2013. A meta-analysis was then performed using the STATA 12.0 software. The crude odds ratios (OR) with 95% confidence intervals (CI) were calculated. RESULTS Eleven case-control studies were included with a total of 10,252 subjects, including 5429 MI patients and 4823 healthy controls. Our meta-analysis results indicated that IL-6 -174 G/C polymorphism may increase the risk of MI (C allele vs. G allele: OR=1.07, 95% CI: 1.01-1.14, p=0.018; GC+CC vs. GG: OR=1.14, 95% CI: 1.04-1.24, p=0.003; respectively). However, our results showed no significant association between IL-6 -572 G/C polymorphism and MI risk (C allele vs. G allele: OR=0.88, 95% CI: 0.75-1.03, p=0.098; GC+CC vs. GG: OR=0.87, 95% CI: 0.70-1.07, p=0.173; respectively). No publication bias was detected in this meta-analysis. CONCLUSION The current meta-analysis suggests that IL-6 -174 G/C polymorphism may contribute to MI susceptibility. Thus, detection of IL-6 -174 G/C polymorphisms may be a promising biomarker for the early detection of MI. However, IL-6 -572 G/C polymorphism may not associate with the risk of MI.

Abstract
OBJECTIVES Polymorphisms in the Interleukin (IL)-1-related genes at the locations -889, -511, + 3962 and mspa1l 1100 have been investigated for possible association with Behçet's disease (BD). METHODS A literature-based search was conducted to identify all relevant studies. Five independent studies from Turkish population met the included criteria. RESULTS IL-1α -889 CT [odds ratio (OR) = 0.72, 95% confidence interval (CI) = 0.55-0.95], IL-1α -889 TT (OR = 0.61, 95% CI = 0.40-0.93), IL-1β + 3962 C (OR = 1.41, 95% CI = 1.07-1.88), IL-1β + 3962 T (OR = 0.71, 95% CI = 0.53-0.94) IL-1β + 3962 CC (OR = 2.08, 95% CI = 1.08-3.99), IL-1β + 3962 CT (OR = 0.58, 95% CI = 0.38-0.88), IL-1 receptor antagonist (IL-1 Ra) mspa1l 1100 CT (OR = 0.69, 95% CI = 0.49-0.96), IL-1 Ra mspa1l 1100 TT (OR = 1.50, 95% CI = 1.08-2.08) had a significant association with BD. The pooled estimates for IL-1α -889 C, IL-1α -889 CC, IL-1α -889 T had a non-significant association with BD. CONCLUSIONS IL-1α -889 CT, IL-1α -889 TT, IL-1β + 3962 C, IL-1β + 3962 T, IL-1β + 3962 CC, IL-1β + 3962 CT, IL-1 Ra mspa1l 1100 CT, IL-1Ra mspa1l 1100 TT promoter polymorphisms may confer susceptibility to BD in Turkish population.
