Pathway Phenotypes Underpinning Depression, Anxiety, and Chronic Fatigue Symptoms Due to Acute Rheumatoid Arthritis: A Precision Nomothetic Psychiatry Analysis. J Pers Med 2022; 12:jpm12030476. [PMID: 35330475 PMCID: PMC8950237 DOI: 10.3390/jpm12030476] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 02/19/2022] [Accepted: 03/08/2022] [Indexed: 12/12/2022] Open
Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory and autoimmune disorder which affects the joints in the wrists, fingers, and knees. RA is often associated with depressive and anxiety symptoms as well as chronic fatigue syndrome (CFS)-like symptoms. This paper examines the association between depressive symptoms (measured with the Beck Depression Inventory, BDI), anxiety (Hamilton Anxiety Rating Scale, HAMA), CFS-like (Fibro-fatigue Scale) symptoms and immune–inflammatory, autoimmune, and endogenous opioid system (EOS) markers, and lactosylcer-amide (CD17) in RA. The serum biomarkers were assayed in 118 RA and 50 healthy controls. Results were analyzed using the new precision nomothetic psychiatry approach. We found significant correlations between the BDI, FF, and HAMA scores and severity of RA, as assessed with the DAS28-4, clinical and disease activity indices, the number of tender and swollen joints, and patient and evaluator global assessment scores. Partial least squares analysis showed that 69.7% of the variance in this common core underpinning psychopathology and RA symptoms was explained by immune–inflammatory pathways, rheumatoid factor, anti-citrullinated protein antibodies, CD17, and mu-opioid receptor levels. We constructed a new endophenotype class comprising patients with very high immune–inflammatory markers, CD17, RA, affective and CF-like symptoms, and tobacco use disorder. We extracted a reliable and replicable latent vector (pathway phenotype) from immune data, psychopathology, and RA-severity scales. Depression, anxiety, and CFS-like symptoms due to RA are manifestations of the phenome of RA and are mediated by the effects of the same immune–inflammatory, autoimmune, and other pathways that underpin the pathophysiology of RA.

Association of Interleukin-10 -592 C > A gene polymorphism with coronary artery disease: A case-control study and meta-analysis. Cytokine 2021; 139:155403. [PMID: 33472122 DOI: 10.1016/j.cyto.2020.155403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2018] [Revised: 10/14/2020] [Accepted: 12/07/2020] [Indexed: 10/22/2022]
Abstract
BACKGROUND Coronary-artery-disease (CAD) is the leading cause of death worldwide, and hence there is a need to identify reliable markers for identifying individuals at high risk of developing CAD. Interleukin-10 (IL-10) is an anti-inflammatory cytokine that is associated with an increased risk of developing both atherosclerosis and acute coronary events. The study aimed to explore the association of a genetic variant in IL-10 with the risk of developing CAD and the severity of the disease. To further explore, a systematic review and meta-analysis was performed. The cumulative results of the relationship between IL and 10 -592 C > A polymorphism and CAD in Iranian population have also been presented. METHODS In this cross sectional study, a total of 948 individuals including 307 healthy controls and 641 patients that among cases, four hundred and fifty-five of the patients had > 50% stenosis (angiogram positive group) and 186 patients had < 50% stenosis (angiogram negative group) were recruited from the Mashhad-Stroke and Heart-Atherosclerotic-Disorders cohort. Genotyping for the IL-10 -592 C > A polymorphism was performed using a PCR-RFLP technique, and statistical analysis undertaken by univariate and multivariate analyses. PubMed, Google Scholar and Scopus were searched for papers related to this polymorphism up to October 2019. The Meta-analysiswas done based on the random effect model using a Meta-analysis. RESULTS In our study, the frequency of the variant A allele of the IL-10 -592 C > A was significantly higher in CAD patients than the control group (P value = 0.043). Moreover, subjects carrying AA genotype had a significantly higher risk of CAD (OR: 1.8, 95%CI: 1.04-3.16), p = 0.03), compared to those with the wild type genotype. The results of meta-analysis of 9336 cases and 8461 controls did not also show any significant association between IL and 10 -592 C > A and CAD in dominant and recessive genetic models but only in co-dominant model when fix effect was applied. CONCLUSION Although our research findings support a significant association of genetic polymorphism in the IL10 gene with cardiovascular diseases, this finding cannot be confirmed in meta-analysis. Further functional analysis and evaluation of this marker in a multicenter setting are needed to establish its value as a risk stratification marker.

Abstract
BACKGROUND Pleiotropic cytokine interleukin-10 (IL-10) has been suggested as modifying risk for atherosclerosis. Promoter region genetic polymorphism of IL-10 gene is known to be associated with the level of IL-10 production. Through these effects, they might be involved with the ischemic stroke (IS). Our aim was to assess the nature of the functional polymorphisms in IL-10 promoter and any links with IS in Chinese Han population. METHODS The IL-10 -1082 G>A, -819 C>T and -592 C>A functional polymorphisms were determined by TaqMan SNP Genotyping assays in 1296 subjects (648 IS patients diagnosed by CTs or/and magnetic resonance imaging (MRI) and 648 normal healthy controls from Chinese Han Population). Multivariate logistic regression analysis was used to show the association between the IL-10 genotypes and the IS events. RESULTS We found that the CC genotype of -819 C>T was more common in controls than IS subjects (P<0.05, corrected for multiple testing) in the Han population. CC carriage may be associated with the decreased risk of IS in the Han ethnic group (OR 0.65, 95% CI 0.43-0.97). In addition, the CC genotype in -592 C>A and GG genotype in -1082 G>A are all extremely low in Chinese Han cases and controls. CONCLUSIONS The G allele frequency at the -1082 promoter region of IL-10 was rare in Chinese Han population which are diffierent from American/European populations.. IL-10 -819 C>T may be an independent protective factor for IS in the Chinese Han population.

CD14 brightCD16+ intermediate monocytes are induced by interleukin-10 and positively correlate with disease activity in rheumatoid arthritis. Arthritis Res Ther 2017; 19:28. [PMID: 28183329 PMCID: PMC5301443 DOI: 10.1186/s13075-016-1216-6] [Citation(s) in RCA: 58] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2016] [Accepted: 12/30/2016] [Indexed: 12/29/2022] Open
Abstract
Background Three different subsets of circulating human monocytes, CD14brightCD16- (classical), CD14brightCD16+ (intermediate), and CD14dimCD16+ (non-classical) have been recently identified. It has been reported that CD14brightCD16+ monocytes are increased in rheumatoid arthritis (RA). However, the role of each monocyte subset in the pathogenesis of RA is still unclear. The purpose of this study was to investigate the association of CD14brightCD16+ monocytes with RA. Methods The study enrolled 35 patients with RA and 14 healthy volunteers. The three subsets of peripheral blood monocytes were analyzed by flow cytometry. Serum cytokines were measured at baseline in patients with RA and in healthy volunteers. CD14brightCD16- monocytes were isolated and cultured in vitro with different cytokines for 14 hours, and CD16 induction was assessed. Results The proportion of CD14brightCD16+ monocytes, and serum interleukin (IL)-6, IL-8, and IL-10 were increased in patients with RA compared to healthy controls. The proportion of CD14brightCD16+ monocytes correlated with the disease activity of RA positively, whereas the proportion of CD14brightCD16- monocytes correlated negatively. When isolated CD14brightCD16- monocytes were stimulated with IL-6, IL-8, and IL-10, the only cytokine that significantly induced CD16 expression on the cells was IL-10. Conclusions The proportion of CD16brightCD14+ monocytes was positively correlated with RA disease activity. The expression of CD16 in monocytes was induced by IL-10 but not IL-6, and IL-8 was enhanced in the sera of patients with RA. Our results suggest that CD16brightCD14+ monocytes are involved in the pathogenesis of RA and that IL-10 is a key cytokine that regulates CD16 expression in monocytes.

Abstract
Atherosclerosis is considered as an inflammatory disease, and carotid artery intima-media thickness (IMT) and carotid plaque are generally used as intermediated phenotype of atherosclerosis. The aim of this study was to investigate whether carotid IMT and plaque are associated with promoter region polymorphisms of interleukin 10 (IL-10) gene. We recruited 135 subjects from a rural area of south-eastern part of South Korea. Three polymorphisms in the promoter region of IL-10 (-1082 A/G, -819 T/C and -592 A/C) were genotyped by pyrosequencing. Carotid IMT was measured at common carotid arteries, and carotid bulbs and cardiovascular risk factors such as cholesterol, blood pressure, uric acid and homocysteine were measured using blood samples. Subjects with the minor allele (C) of -819 T/C or the minor allele (C) of -592 A/C showed lower values in carotid IMT than those with major allele homozygote of each polymorphism (P = 0.018 and P = 0.031, respectively). Subjects with carotid plaque were significantly older and showed higher values in carotid IMT, uric acid and homocysteine than those without plaque (P < 0.01, respectively). In conclusion, the promoter region polymorphisms of IL-10 gene associate with carotid IMT and plaque. Further studies with larger samples are needed to provide stronger evidence to justify anti-atheromatous properties of IL-10.

Abstract
Interleukin-10 (IL-10) has
been recently identified as a multifunctional cytokine, because of its close link with
immunoregulation and anti-inflammatory responses. This study investigated the association
of IL-10 genetic polymorphisms with the immune traits of New Zealand white rabbits (N-W),
Fujian yellow rabbits (F-Y) and their reciprocal crosses (N-Y and Y-N, respectively). SNPs
on five exons of the IL-10 gene were genotyped in 204 healthy rabbits via PCR-SSCP and DNA
sequencing. Two SNPs (A1435G and G1519A, both were synonymous mutations) and six genotypes
(AA, BB, CC, AB, AC and BC) were found on exon 3 and one SNP (T base insertion between
loci 2532 and 2533, which caused a frameshift mutation), and three genotypes (OO, TT and
TO) were present on exon 4. Allele A was the most frequent allele on exon 3 (from 0.548 to
0.771), whereas O was the most frequent on exon 4 (from 0.808 to 0.968). These four
populations were all in Hardy-Weinberg equilibrium on both exon3 and exon4. Association
analysis between polymorphisms and immune parameters showed that SNPs on exon 3 were
significantly associated with immune traits, while SNP on exon 4 may not significantly
affect immune traits, but the mechanism is yet to be further studied.

Abstract
BACKGROUND Despite evidence of antioxidant effects of vitamin E in vitro and in animal studies, large, randomized clinical trials have not substantiated a benefit of vitamin E in reducing inflammation in humans. An individual's genetic background may affect the response to α-tocopherol supplementation, but this has rarely been investigated. OBJECTIVE The aim of this study was to explore the role of genetic polymorphisms on changes in LPS-stimulated inflammatory cytokine production from peripheral blood mononuclear cells (PBMCs) after α-tocopherol supplementation. DESIGN A total of 160 healthy, middle-aged male volunteers (mean age: 52.7 y) were given dietary supplements of either 75 IU (low dose; n = 57) or 600 IU (high dose; n = 103) α-tocopherol/d for 6 wk. The production of TNF-α and IL-1β, -6, and -10 by PBMCs after LPS stimulation was measured at baseline and after 6 wk. Polymorphisms in 15 genes involved in inflammation or responses to oxidative stress were characterized in the subjects. RESULTS The ability of α-tocopherol to affect TNF-α production by LPS-stimulated PBMCs was influenced by the TNFA -238 polymorphism (P = 0.016). The ability of α-tocopherol to affect IL-6 production was influenced by the GSTP1 313 polymorphism (P = 0.019). The ability of α-tocopherol to affect IL-1β production was influenced by the IL10 -592 and -1082 polymorphisms (P = 0.025 and P = 0.016, respectively). CONCLUSIONS In healthy control subjects, the effect of α-tocopherol supplementation on the production of inflammatory cytokines appears to be dependent on an individual's genotype. These genotype-specific differences may help explain some of the discordant results in studies that used vitamin E.

Abstract
Background A characteristic feature of atherosclerosis is its diffuse involvement of arteries across the entire human body. Bone marrow cells (BMC) can be simultaneously transferred with therapeutic genes and magnetic resonance (MR) contrast agents prior to their transplantation. Via systemic transplantation, these dual-transferred BMCs can circulate through the entire body and thus function as vehicles to carry genes/contrast agents to multiple atherosclerosis. This study was to evaluate the feasibility of using in vivo MR imaging (MRI) to monitor BMC-mediated interleukin-10 (IL-10) gene therapy of atherosclerosis. Methodology For in vitro confirmation, donor mouse BMCs were transduced by IL-10/lentivirus, and then labeled with a T2-MR contrast agent (Feridex). For in vivo validation, atherosclerotic apoE−/− mice were intravenously transplanted with IL-10/Feridex-BMCs (Group I, n = 5) and Feridex-BMCs (Group II, n = 5), compared to controls without BMC transplantation (Group III, n = 5). The cell migration to aortic atherosclerotic lesions was monitored in vivo using 3.0T MRI with subsequent histology correlation. To evaluate the therapeutic effect of BMC-mediated IL-10 gene therapy, we statistically compared the normalized wall indexes (NWI) of ascending aortas amongst different mouse groups with various treatments. Principal Findings Of in vitro experiments, simultaneous IL-10 transduction and Feridex labeling of BMCs were successfully achieved, with high cell viability and cell labeling efficiency, as well as IL-10 expression efficiency (≥90%). Of in vivo experiments, MRI of animal groups I and II showed signal voids within the aortic walls due to Feridex-created artifacts from the migrated BMCs in the atherosclerotic plaques, which were confirmed by histology. Histological quantification showed that the mean NWI of group I was significantly lower than those of group II and group III (P<0.05). Conclusion This study has confirmed the possibility of using MRI to track, in vivo, IL-10/Feridex-BMCs recruited to atherosclerotic lesions, where IL-10 genes function to prevent the progression of atherosclerosis.

Abstract
OBJECTIVE Inflammatory factors modify the risk of coronary heart disease. Pleiotropic cytokine interleukin-10 (IL-10) has been suggested as modifying risk for atherosclerosis. Promoter region genetic polymorphism of IL-10 gene (IL10) is known to be associated with the variation of IL-10 production. We investigated whether single-base exchange polymorphisms -1082 G>A (rs1800896), -819 C>T (rs1800871) and -592 C>A (rs1800872) at IL10 gene are associated with risk factors and early markers of atherosclerosis in young subjects. METHODS AND RESULTS As a part of the Cardiovascular Risk in Young Finns Study, we determined carotid artery compliance (CAC), stiffness index (SI) and Young's elastic modulus (YEM), intima media thickness (IMT), IL10 genotype and atherosclerosis risk parameters for 2260 subjects aged 24-39 years. In male subjects CAC was lower in carriers of IL-10 high- to intermediate-producer haplotype -1082 G; -819 C; -592 C (GCC+, 1.96+/-0.67) than in noncarriers (GCC-, 2.10+/-0.62, %/10 mmHg, mean+/-SD, p=0.0010). An inverse association was observed in SI (GCC+, 5.76+/-2.12 and GCC-, 5.26+/-1.46, p=0.0034) and YEM (GCC+, 347+/-165 and GCC-, 305+/-110, mm Hg.mm, p=0.0005). Associations remained significant when adjusted to age, BMI, smoking and serum lipids as well as fasting glucose and insulin levels. The genetic effect size for these parameters was not significant in women. CONCLUSIONS IL10 promoter region high- to intermediate-producer haplotype GCC associates with decreased arterial elasticity in men. These results are in disconcordance with the supposed antiatheromatous properties of IL-10.
