Abstract
BACKGROUND Interleukin-18 (IL-18) and interferon-γ (IFN-γ) are cytokines of crucial role in inflammation and immune reactions. There is a growing evidence supporting important roles for IL-18 and IFN γ in tuberculosis (TB) infection and anti-tuberculosis immunity. OBJECTIVE To evaluate the role of polymorphisms in IL-18-607 and -137 and INF-γ +874 in susceptibility to TB infection among Egyptian patients. METHODS A case control study was conducted to investigate the polymorphism at IL-18-607, -137 and INF-γ+874 by sequence specific primer-polymerase chain reaction (SSP- PCR) in 105 patients with pulmonary and extra pulmonary tuberculosis and 106 controls. RESULTS A significant protective effect against TB was found in homozygous CC genotype at IL-18 -137G/C, in addition to a 7-fold risk with GG and GC genotypes in the recessive model. Apart from a decreased risk with the AC genotype, no association was detected between the susceptibility to TB and different genotypes or alleles at the IL-18 -607A/C site. The homozygous AA genotype in INF-γ+874 showed a significant higher risk to TB than the homozygous TT or heterozygous AT genotypes with nearly a 2-fold risk of TB infection with the A allele. Regarding haplotype association, the GC haplotype was strongly associated with TB infection compared to other haplotypes. CONCLUSION These findings suggest; for the first time in Egypt; a significant risk to TB infection with SNP at the IL-18-137G/C with no LD with SNP at the IL-18-607 site. The homozygous AA genotype in INF-γ+874 showed a significant higher risk to TB than the homozygous TT or heterozygous AT genotypes.

Abstract
INTRODUCTION The present study aimed to determine the alterations in the serum levels of tumor markers used to evaluate cardiac, renal and liver function, and detect the interleukin (IL)-18 rs1946518 polymorphism in breast (BC), colorectal (CRC) and prostate cancer (PCa) patients. METHODS Blood samples were collected from 65 female BC, 116 CRC, 79 PCa and 88 myocardial infarction (MI) patients, and 110 healthy individuals to determine the concentration of tumor and cardiac markers. Furthermore, the IL-18 rs1946518 polymorphism was assessed using amplification refractory mutation system (ARMS)-PCR. RESULTS The serum levels of the tumor markers cancer antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), carcinoembryonic antigen (CEA) and total prostate-specific antigen (TPSA) were significantly increased in cancer patients compared with healthy controls. Furthermore, the activity of high-sensitivity cardiac troponin T (hs-cTnT) and creatine kinase‑myocardial band (CK-MB) was enhanced in MI patients, however, their activity was unchanged in cancer patients. The activity of alkaline phosphatase (ALP), and the serum concentration of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and urea were markedly elevated in CRC and PCa patients, respectively, compared with the control group. Although, no significant differences were observed in the -607 C/A polymorphism and allele frequency of IL-18 among BC, CRC patients and healthy individuals, the odds ratio (OR) was 1.75 for both C and A allele in BC patients. Therefore, the -607 C/A polymorphism could be considered as a risk factor for BC. CONCLUSION The aforementioned results suggested that tumor markers could be considered as excellent biomarkers for the early detection of BC, CRC and PCa, whereas the concentration of liver enzymes could serve as an alternative indicator for the diagnosis of CRC and PCa. Additionally, the rs1946518 polymorphism in the IL-18 gene could be considered as a risk factor for the occurrence of BC, CRC and PCa.<br />.

Association of interleukin-18 gene polymorphisms with Takayasu arteritis in a Chinese Han population. Chin Med J (Engl) 2020; 133:2315-2320. [PMID: 32826615 PMCID: PMC7546839 DOI: 10.1097/cm9.0000000000001047] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/05/2022] Open
Abstract
Background: Interleukin-18 (IL18) gene polymorphisms are related to many inflammatory and autoimmune diseases. However, a correlation analysis between IL18 −607C/A and −137G/C gene polymorphisms and Takayasu arteritis (TA) is lacking. Methods: This study enrolled 200 patients with TA as the case group and 334 region-, age-, and sex-matched healthy subjects as the control group. We genotyped alleles and genotypes at positions −607 and −137 of the IL18 gene and analyzed the distribution frequencies. Mann-Whitney U test, t test, Chi-squared test and Hardy-Weinberg equilibrium were performed. Results: After adjusting for risk factors, the adjusted odds ratios and 95% confidence intervals at position −607C/A were 0.533, 0.391 to 0.880 (P = 0.010); 0.266, 0.586 to 1.002 (P = 0.051); and 0.122, 0.552 to 1.420 (P = 0.613) under the dominant, additive, and recessive models, respectively. For the −137G/C polymorphism, the adjusted odds ratios and 95% confidence intervals were 1.571, 1.068 to 2.311 (P = 0.022); 1.467, 1.086 to 1.980 (P = 0.012); and 1.815, 0.901 to 3.656 (P = 0.095) under the dominant, additive, and recessive models, respectively. Moreover, regardless of the model used, we found no statistical difference in distribution frequency between the active and quiescent states of TA for the −607C/A (P = 0.355, 0.631, and 0.705, respectively) and −137G/C polymorphisms (P = 0.205, 0.385, and 0.208, respectively). Conclusions: The IL18 −607C/A gene polymorphism may decrease the risk of TA, and thus is a protective factor, whereas −137G/C may increase the risk of TA, and thus is a risk factor. However, neither polymorphism was related to activity (active vs. quiescent) of TA.

Abstract
Many studies have demonstrated that (IL-18) polymorphisms (including -137C/G and
-607A/C) are correlated with the risk of tuberculosis. However, the meaning of
this finding remains a matter of debate. In this study, electronic databases,
including PubMed, EMBASE, Web of Science, Google Scholar and CNKI, were
systemically queried to identify relevant studies. Subsequently, odds ratios and
corresponding 95% confidence intervals were analysed. Our data indicated that
the IL-18 -137C/G polymorphism was not related to tuberculosis susceptibility
(GG vs. AA odds ratio = 0.71, 95% confidence interval 0.43–1.17; GA vs. AA: odds
ratio =0.80, 95% confidence interval 0.57–1.13; dominant model: odds
ratio = 0.78, 95% confidence interval 0.56–1.08; recessive model: odds
ratio = 0.76, 95% confidence interval 0.46–1.25). Similarly, there was no
association between the IL-18 -607A/C polymorphism and tuberculosis
susceptibility (AA vs. CC: odds ratio = 1.25, 95% confidence interval 0.87–1.79;
CA vs. CC: odds ratio = 1.10, 95% confidence interval 0.93–1.29; dominant model:
odds ratio = 1.13, 95% confidence interval 0.90–1.41; recessive model: odds
ratios=1.17, 95% confidence interval 0.90–1.53). No association was found in the
subgroup analysis based on the Hardy–Weinberg equilibrium. In addition, there
was no publication bias. The two IL-18 gene polymorphisms (-137C/G and -607A/C)
were not markedly correlated with tuberculosis susceptibility. Well-designed
studies with more subjects will be required for further validation of these
results.

Abstract
Objective To investigate the association between IL-18 polymorphisms and Tuberculosis(TB). Materials and methods We searched PubMed and Embase databases, and conducted a meta-analysis using 4 models. Data were extracted from the studies by two independent reviewers. Statistical analysis was performed using STATA 12.0 software. Results Five qualified studies with a total of 1293 TB patients and 1724 controls were included. There was no significant association between the IL-18 -607C>A polymorphism and TB risk in the total population(AA vs CC: OR=1.27,95% CI=0.82–1.96;-CA vs CC:OR=1.06,95% CI=0.89–1.26; Dominant model: OR =1.09, 95% CI =0.83–1.43; Recessive model:OR=1.23, 95% CI=0.92–1.65). For IL-18 -137G>C polymorphism, lack of an association was also found(GG vs CC: OR=1.42,95% CI=0.78–2.58;GC vs CC:OR=1.16,95% CI=0.62–2.16; Dominant model: OR =1.34,95% CI=0.74–2.43;Recessive model:OR=0.96,95%-CI=0.26–3.56). Conclusion The present meta-analysis found no evidence for IL-18 -607C>A and -137G>C polymorphisms as risk factors for TB. Further large-scale and well-designed articles are still needed to validate this result.

Abstract
OBJECTIVE We aim to explain the correlation among IL-18 gene polymorphism, its protein expression and LEDVT in the Chinese Han population. METHODS A total of 138 LEDVT patients and 150 healthy people volunteered as LEDVT and control groups. All the data, including the gender, age, BMI, levels of TG, LDL/HDL, TC, GLU, APTT, BUN, Cr, ALT, AST, ApoA1, ApoB, and Fg was detected. IL-18 level, IL-18 -137G/C and -607C/A polymorphism, and risk factors of LEDVT were detected using ELISA, PCR-RFLP and multivariate logistic regression analysis, respectively. RESULTS Increased BMI, GLU, Fg, BUN, ApoB and IL-18 and decreased APTT were found in the LEDVT group. The GC + CC genotype and C allele in -137G/C polymorphism was elevated in the control group when compared to that in the LEDVT group. The IL-18 level was elevated in the case group when compared to the control group with respect to the same genotype in -607C/A and -137G/C polymorphisms, and in the LEDVT group, IL-18 level was higher in the GG genotype than that in the GC + CC genotype of -137G/C polymorphism. BUN, GG genotype and IL-18 level were independent risk factors, but APTT was a protective factor of LEDVT. CONCLUSION On the basis of our results, we concluded that the GG genotype of -137G/C polymorphism and IL-18 level are independent risk factors of LEDVT, and IL-18 gene polymorphism affects the level of IL-18 in LEDVT patients.

Abstract
PURPOSE Association of cytokine genes reflects their susceptibility towards infection and disease in household contacts (HHC) of pulmonary tuberculosis (PTB) patients. Hyperglycemia, a common factor in diabetics might influence their risk towards mycobacterium tuberculosis infection and disease development. This study determines the association of IL-6 and IL-18 cytokine gene variants of TB patients with diabetes mellitus (TBDM) and their HHC in Hyderabad. METHODS Single nucleotide polymorphisms of IL-6 (-174 G>C and -572 G>C) and IL-18 (-137 G>C and -607 C>A) cytokine genes were genotyped by Amplification Refractory Mutation System and Restriction Fragment Length polymerase chain reaction in total of 705 subjects comprising of TBDM, their HHC, PTB, DM and Healthy controls (HC). RESULTS At IL-6 -174G>C variant, GG genotype, G allele in TBDM and TBDM HHC, at -572G>C variant, C allele in TBDM and GG haplotype in TBDM HHC were showing positive association, however DM have not shown any association at IL-6 polymorphic sites. With respect to the IL-18 gene polymorphisms, at -137 G>C variant, GG genotype was positively associated in PTB while at -607 C>A variant positive association was shown with AC genotype in TBDM, their HHC and DM; GACC diplotype in TBDM and GCGC in PTB. CONCLUSION Our findings suggest that susceptible combination of IL-6 and IL-18 cytokine genes associated with disease in the HHCs highlight their risk of inclination towards the disease.

Abstract
BACKGROUND Interleukin (IL) -18 is crucial to host defense against mycobacterial infections. Recent studies have indicated IL-18 gene polymorphisms are associated with susceptibility to several clinical diseases. OBJECTIVE The aim of this study is to investigate the association of IL-18 (-137G/C and -607C/A) gene promoter single nucleotide polymorphisms (SNPs) with susceptibility to tuberculosis (TB), and the effects of those SNPs to its protein producing capacity in Chinese Han population. METHODS 407 TB patients (including 113 children and 294 adults) and 469 healthy volunteers (including 167 children and 302 adults) from Chinese Han population were enrolled. The IL-18 gene promoter polymorphisms at positions of -137 and -607 were determined by sequence specific primer-polymerase chain reaction (SSP-PCR). The IL-18 levels in the supernatants of PBMCs from 46 healthy volunteers were measured by ELISA. RESULTS The gene distribution of IL-18 -137G/C and -607C/A showed none difference between adult and pediatric population. The frequency of IL-18 -137GG genotype was significantly higher in total TB group than that in total healthy control group (79.1% V 69.3%, P<0.01), while the frequencies of GC genotype and C allele were conversely lower (19.2% V 27.9%, P<0.01; 11.3% V 16.7%, P<0.01 respectively). The difference of the -137CC genotype distribution between patients and controls was not observed. At the -607C/A polymorphic site, patient and control groups had a very similar gene distribution. Isolated PBMCs with IL-18 -137GC/CC genotype were able to produce a higher level of IL-18 than those with IL-18 -137GG genotype, either spontaneously or in response to PMA plus calcimycin A23187. CONCLUSION IL-18 -137G/C polymorphism contributed to TB susceptibility in Chinese Han population. Allele G might be a predisposing gene of TB, while allele C probably plays a role in preventing mycobacterium tuberculosis infection by promoting more vigorous protein expression.

Abstract
It is known that interleukin-18 (IL-18) is a proinflammatory cytokine with dual effects on tumor development and progression. It can increase the immune defense against tumor cells. Polymorphisms in the IL-18 genes are known to influence both expression levels and may be associated with outcome of cancers. This study was aimed to find out the possible association of IL-18 polymorphism at position –607 C/A (rs1946518) with breast cancer in a sample of Iranian population. We investigated IL-18 rs1946518 polymorphism on 72 breast cancer patients and 93 cancer free women. Genotyping was done using amplification refractory mutation system-PCR (ARMS-PCR). We found no significant differences between breast cancer patients and control subjects regarding IL-18 rs1946518 polymorphism (χ2=1.78, p=0.411). In conclusion, our finding showed that IL-18 rs1946518 polymorphism was not associated with breast cancer in a sample of Iranian population.

Abstract
This current meta-analysis of case-control studies was continued to investigate whether the genetic polymorphisms of IL-18 gene contribute to the occurrence and progression of tuberculosis (TB). We searched certain English and Chinese databases for relevant studies without language restrictions. Meta-analysis for the moment was performed with the adoption of the STATA statistical software. Crude OR and its corresponding 95 % confidence interval (95 % CI) were calculated as estimates of relative risk for UC under different genetic models. Seven case-control studies (TB patients = 1,325, healthy subjects = 1,778) were included for the following analysis. We evaluated two functional polymorphisms (rs1946518 C>A and rs187238 G>C). Pooled OR within the progression of statistical analysis indicated that the specific polymorphism of IL-18 rs1946518 C>A showed a closely relationship with the elevated susceptibility to TB under those three genetic models (allele model: OR 1.24, 95 % CI 1.11-1.38, P < 0.001; dominant model: OR 1.41, 95 % CI 1.21-1.65, P < 0.001; homozygous model: OR 1.46, 95 % CI 1.15-1.86, P = 0.002; respectively). However, we observed no statistical associations of the IL-18 rs187238 G>C polymorphism with the susceptibility to TB under any of the genetic models (all P > 0.05). Country-stratified analysis results detected that the variants of IL-18 may be strongly enrolled in the risk of TB among populations in China (allele model: OR 1.19, 95 % CI 1.06-1.33, P = 0.003; recessive model: OR 1.54, 95 % CI 1.00-2.36, P = 0.048; homozygous model: OR 1.59, 95 % CI 1.09-2.33, P = 0.016; respectively), but not among populations in Iran, Korea and India (all P > 0.05). Current results provide strong evidence that IL-18 mutations may be evidently related to the occurrence and development of TB, especially for the rs1946518 C>A polymorphism among populations in China.

Abstract
OBJECTIVE A clinical investigation of the potential correlation of two single-nucleotide polymorphisms at -137 (G/C) and -607 (C/A) in the promoter region of the IL-18 gene, with the susceptibility to aphthous stomatitis and Behçet's disease. PATIENT AND METHODS This study included 80 aphthous stomatitis patients and 80 patients with Behçet's disease. Eighty healthy subjects were enrolled as a control group. IL-18 single-nucleotide polymorphisms at -607 and -137 regions were analyzed using polymerase chain reaction-restriction fragment length polymorphism analysis. RESULTS The genotype and allele distributions of the two regions did not differ significantly between patients with aphthous stomatitis and controls. The genotype and allele distributions at -607 were significantly different between patients with Behçet's disease [CC (P = 0.044), C allele (P = 0.043), A allele (P = 0.043)], and controls. The frequency of the GG genotype at position -137 in patients with Behçet's disease was associated only with a higher rate of ocular manifestations (OR= 1.4, CI= 0.76-2.7, P = 0.031). CONCLUSION IL-18 gene polymorphisms were not associated with any susceptibility to aphthous stomatitis, while a positive association was found with patients with Behçet's disease regarding -607 promoter site. Moreover, patients with Behçet's disease carrying the GG genotype at position -137 had a higher risk of developing ocular manifestations.

Abstract
AIM The aim this work is to estimate whether genetic polymorphisms of +874 of IFN-γ and -137 G/C,-607 C/A of IL-18 genes are implicated in the development of VUR, because a vast literature indicates that genetic variations play a significant role in the pathogenesis of VUR. MATERIALS AND METHODS The PCR single specific primer (SSP) and amplification refractory mutation system (ARMS) were applied for analyzing the polymorphic sites of -137 G/C,-607 C/A of IL-18 and +874 of IFN-γ genes in 110 healthy controls and 124 VUR children. RESULTS A significant relationship was found between AT and combined AT + TT genotypes of IFN-γ and highly increased risk of VUR (OR = 4.2, 95% CI, 2.00-9.24; p < 0.0001: OR = 4.00, 95% CI, 1.90-8.70, p < 0.0001, respectively). On the other hand, the genotype frequency of IL18-137 G/C indicated a significant assessment of the decrease risk of VUR for GC and GC + CC genotypes (OR = 0.53, 95% CI, 0.3-0.9; p = 0.02: OR = 0.53, 95% CI, 0.3-0.92 p = 0.01, respectively). No significant association was found between -607 C/A polymorphism of IL-18 and UVR. CONCLUSION To the author's best knowledge, this is the first data regarding polymorphism of IFN-γ (+874) cytokine genes that highly increased the risk of VUR. To confirm the presented data, further studies should be done in different populations with a larger sample size.
