The Predictive Value of Serum Cytokines for Distinguishing Celiac Disease from Non-Celiac Gluten Sensitivity and Healthy Subjects. IRANIAN BIOMEDICAL JOURNAL 2020; 24:340-6. [PMID: 32660201 PMCID: PMC7601547 DOI: 10.29252/ibj.24.6.335] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/03/2019] [Accepted: 11/23/2019] [Indexed: 02/07/2023]
Abstract
Background It has been established that the level of some inflammatory cytokines increases in celiac disease (CD) and non-celiac gluten sensitivity (NCGS) in comparison with healthy subjects. Therefore, the primary interest in our research was proposing an accurate tool to diagnose patients with CD and NCGS from healthy individuals in an Iranian population. Methods The serum samples were examined in 171 participants, including 110 CD patients, 46 healthy individuals, and 15 NCGS. The commercial ELISA kits were used to detect the level of the following cytokines: IL-1, IL-6, IL-8, IL-15, and IFN-γ. The receiver operating characteristic (ROC) curve analysis was applied to determine the optimal thresholds for high sensitivity, specificity, positive and negative predictive values of cytokines, as the indicators of CD, NCGS, and healthy control groups. Results In NCGS group, the values of area under the ROC curve for IL-1, IL-8, and IFN-γ were 71%, 78%, and 70%, respectively. To differentiate the CD and NCGS groups from the control group, IL-15 had the highest sensitivity (82.70%), specificity (56.50%), positive predictive value (81.98%), and negative predictive value (57.78%), followed by IL-8 with the highest sensitivity of 74.50%, specificity of 73.30%, and positive and negative predictive values of 95.35% and 30.21%, respectively. Conclusion The obtained results demonstrate that IL-15 and IL-8 could be proposed as potential markers in their optimal cut-off points for distinguishing CD from the NCGS and the healthy control. Based on our findings, the evaluation of cytokine levels can be recommended as a useful tool for the diagnosis of CD and NCGS in a clinical practice.

Abstract
OBJECTIVE To evaluate sex-specific genetic susceptibility to adverse neurodevelopmental outcome (ANO, defined as cerebral palsy [CP], mental, or psychomotor delay) at risk for early preterm birth (EPTB, < 32 weeks). STUDY DESIGN Secondary case-control analysis of a trial of magnesium sulfate (MgSO4) before anticipated EPTB for CP prevention. Cases are infants who died by the age of 1 year or developed ANO. Controls, matched by maternal race and infant sex, were neurodevelopmentally normal survivors. Neonatal DNA was evaluated for 80 polymorphisms in inflammation, coagulation, vasoregulation, excitotoxicity, and oxidative stress pathways using Taqman assays. The primary outcome for this analysis was sex-specific ANO susceptibility. Conditional logistic regression estimated each polymorphism's odds ratio (OR) by sex stratum, adjusting for gestational age, maternal education, and MgSO4-corticosteroid exposures. Holm-Bonferroni corrections, adjusting for multiple comparisons (p < 7.3 × 10-4), accounted for linkage disequilibrium between markers. RESULTS Analysis included 211 cases (134 males; 77 females) and 213 controls (130 males; 83 females). An interleukin-6 (IL6) polymorphism (rs2069840) was associated with ANO in females (OR: 2.6, 95% confidence interval [CI]: 1.5-4.7; p = 0.001), but not in males (OR: 0.8, 95% CI: 0.5-1.2; p = 0.33). The sex-specific effect difference was significant (p = 7.0 × 10-4) and was unaffected by MgSO4 exposure. No other gene-sex associations were significant. CONCLUSION An IL6 gene locus may confer susceptibility to ANO in females, but not males, after EPTB.

ARQUIVOS DE GASTROENTEROLOGIA 2019; 56:323-328.

Abstract
BACKGROUND There has been little evidence to suggest that the IL-6 -174G>C and IL-10 -1082A>G polymorphisms are significantly associated with susceptibility to celiac disease. Thus, we performed the present meta-analysis to explore the potential association between these polymorphisms and celiac disease risk. METHODS Eligible studies were searched in PubMed, Medline, Embase, Web of Science and CNKI database up to April 20, 2019. Odds ratios with 95% confidence interval were calculated to assess the potential associations. Moreover, we performed the heterogeneity, sensitivity, and publication bias tests to clarify and validate the pooled results. RESULTS Overall, nine case-control studies involving five studies with 737 cases and 1,338 control on IL-6 -174G>C polymorphism and four studies with 923 cases and 864 controls on IL-10 -1082A>G polymorphism were selected. The pooled ORs showed that the IL-6 -174G>C and IL-10 -1082A>G polymorphisms were not significantly associated with increased risk of celiac disease under all five genetic models. There was no publication bias. CONCLUSION To the best of our knowledge, this is the first meta-analysis summarizing all of the available studies on the association of IL-6 -174G>C and IL-10 -1082A>G polymorphisms with celiac disease. Our results suggest that the IL-6 -174G>C and IL-10 -1082A>G polymorphisms may not be associated with increased risk of celiac disease. Moreover, large and well-designed studies are needed to fully describe the association of IL-6 -174G>C and IL-10 -1082A>G polymorphisms with celiac disease.

Abstract
Introduction Celiac disease (CD) is a chronic inflammatory intestinal disorder. Different
immunological factors, including inflammatory cytokines, may play an important role in
disease susceptibility. Aim To investigate the relationship between -174G/C and -572G/C gene polymorphisms and the
serum level of interleukin 6 (IL-6) and susceptibility to CD in the Iranian
population. Material and methods In this case-control study blood samples were collected of 105 patients with CD and 106
healthy subjects randomly in 2016 and evaluated by polymerase chain reaction-restriction
fragments length polymorphism (PCR-RFLP) method. A sequence was also used to confirm the
results of both polymorphisms. The IL-6 concentration was measured using ELISA. Results The results showed a significant relationship between polymorphism -572G in CD patients
when compared with control subjects by genotype (p = 0.001) and alleles
(p = 0.022), respectively. There was no significant relationship
between polymorphism 174G and frequency of genotype, but an association of this
polymorphism with the frequency of alleles (p = 0.034), age
(p = 0.001), and body mass index (p = 0.003) was
seen. The serum level of interleukin-6 was significantly associated only with rs1800796
(p < 0.001). Conclusions The results confirm previous studies in different parts of the world and indicate that
IL-6 (572G/C) polymorphism may play a role in susceptibility to CD in the Iranian
population.

Abstract
Coeliac disease is an autoimmune disorder triggered by gluten intake, causing intestinal inflammation and mucosal damage commonly associated with the malabsorption of nutrients and ferropenic anaemia. The present study evaluates the effects of the oral administration of Bifidobacterium longum CECT 7347 on gliadin-mediated alterations in hepatic Fe deposition and Hb concentration, liver transferrin receptor (TfR)-2, IL-6, TNF-α and hepcidin (Hamp) expression (mRNA), and active hepcidin peptide production by liquid chromatography–MS/MS. Weanling rats, sensitised or not with interferon (IFN)-γ, were fed with gliadins and/or the bifidobacterial strain. Gliadin feeding increased hepatic Fe deposition; however, only gliadin-fed sensitised animals showed lower Hb concentrations than the controls. TfR2 expression decreased after gliadins were fed to both sensitised and non-sensitised animals,and restored by the administration of B. longum. These observations were accompanied by increases in IL-6 expression levels in all the treatment groups; however, TNF-α expression only increased significantly in animals fed gliadins alone or together with B. longum if they had previously been sensitised with IFN-γ. Liver expression levels of Hamp diminished in all cases to the lowest values in animals sensitised with IFN-γ after being fed with gliadins and/or bifidobacteria. In these animals, plasma Hamp active peptide concentrations significantly increased when compared with the controls. Significant correlations were calculated between Hamp expression and liver Fe contents (liver Fe = 1/0·0032 + 0·032 x Hamp(exp)), and Hb concentrations (Hb = 11·49 + 10·13 x (Hamp(exp))1/2). These data indicate that oral administration of B. longum ameliorates gliadin-mediated perturbations in liver Fe deposition and mobilisation.

Abstract
Th17 cells are known to be involved in several autoimmune or inflammatory diseases. In celiac disease (CD), recent studies suggest an implication of those cells in disease pathogenesis. We aimed at studying the role of genes relevant for the Th17 immune response in CD susceptibility. A total of 101 single nucleotide polymorphisms (SNPs), mainly selected to cover most of the variability present in 16 Th17-related genes (IL23R, RORC, IL6R, IL17A, IL17F, CCR6, IL6, JAK2, TNFSF15, IL23A, IL22, STAT3, TBX21, SOCS3, IL12RB1 and IL17RA), were genotyped in 735 CD patients and 549 ethnically matched healthy controls. Case-control comparisons for each SNP and for the haplotypes resulting from the SNPs studied in each gene were performed using chi-square tests. Gene-gene interactions were also evaluated following different methodological approaches. No significant results emerged after performing the appropriate statistical corrections. Our results seem to discard a relevant role of Th17 cells on CD risk.

Abstract
Background To analyze the potential genetic associations between four polymorphisms of interleukin-6 receptor (IL-6R) gene and atherosclerotic lipid profiles among young adolescents in Taiwan. Methods Using data from the Taipei Children Heart Study-II - a cross-sectional survey in 2003. After multi-stage sampling, we selected 418 boys and 441 girls with an average age of 13.1 years. We genotyped the subjects for four IL-6R gene polymorphisms (rs4845617 G/A, rs4845623 A/G, rs8192284 A/C, and rs2229238 C/T) using a TaqMan 5' nuclease assay. Lipid profiles, including total cholesterol (CHOL), triglycerides (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C) were measured using standard methods. We also calculated CHOL/HDL-C ratio, LDL-C/HDL-C ratio, and TG/HDL-C ratio as atherosclerotic indexes. Results IL-6R rs8192284 A/C and rs2229238 C/T variants showed strong associations with high TG (additive model, OR = 1.58, 95%CI: 1.05-2.37; OR = 1.55, 95%CI: 1.04-2.29, respectively), low HDL-C (additive model, OR = 1.57, 95%CI: 1.03-2.39; OR = 1.68, 95%CI: 1.12-2.52, respectively), and high CHOL/HDL-C (additive model, OR = 1.68, 95%CI: 1.08-2.61, OR = 1.82, 95%CI: 1.18-2.79, respectively) in girls. We inferred five common haplotypes using rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T (GAC, GAT, GGC, AAC, and AAT). In girls, the AAT haplotype was associated with a significant risk of high TG, low HDL-C, high CHOL/HDL-C, and abnormal lipid levels (high TG or low HDL-C) when compared with the GAC haplotype (OR range = 3.08-4.40, all p < 0.05). Conclusion The IL-6R rs8192284 A/C and rs2229238 C/T variants are associated with dyslipidemia in girls, but not in boys. The AAT haplotype of the IL-6R gene (rs4845617 G/A, rs4845623 A/G, and rs2229238 C/T) may play an important role in the pathogenesis of dyslipidemia and atherosclerosis in girls.
