Cumulative Evidence for Association between IL-10 Polymorphisms and Kawasaki Disease Susceptibility: A Systematic Review and Meta-Analysis.

BACKGROUND: This meta-analysis was carried out to evaluate the associations between IL-10 polymorphisms and Kawasaki disease (KD) risk. METHODS: A comprehensive literature search was performed using PubMed, EMBASE, China National Knowledge Infrastructure and SciELO for all relevant studies evaluating IL-10 polymorphism and susceptibility to KD. The associations were measured by odds ratios (ORs) and its corresponding 95% confidence intervals (CIs). RESULTS: A total of 13 studies including four studies on -1082 A > G, four studies on -819 T > C and five studies on -592 A > C polymorphism were selected. Pooled data revealed that IL-10 -592 A > C polymorphism was significantly associated with an increased risk of KD (C vs. A: OR = 0.402, 95% CI 0.194-0.832, p = 0.014). However, IL-10 -1082 A > G and -819 T > C polymorphisms were not significantly associated with risk of KD under all five genetic models. CONCLUSIONS: Our results revealed that IL-10 -592 A > C polymorphism was associated with risk of KD, while IL-10 -1082 A > G and -819 T > C polymorphisms were not involved in the development of KD.

Association of IL-6 -174G > C and -572G > C Polymorphisms with Risk of Legg-Calve-Perthes Disease in Iranian Children.

BACKGROUND: Legg-Calve-Perthes disease (LCPD) is an idiopathic avascular necrosis of the capital femoral epiphysis of the femoral head with multifactorial etiology. The aim of this study was to analyze the association of IL-6 polymorphisms with LCPD risk in Iranian children. Methods: The study comprised of 45 children diagnosed with LCPD and 60 healthy subjects. The IL-6 -174 G > C and -597 G > C polymorphisms were genotyped by PCR-RFLP assay. Odds ratios (OR) and 95% confidence intervals (CI) were calculated on the risk genotypes and alleles. Results: The mutant homozygote genotype (CC) of IL-6 -174 G > C polymorphism was associated with increased risk of LCPD (OR 3.554; 95% CI: 0.1.578-8.004; p = 0.002). There was no significant association between IL-6 -597 G > C polymorphism and an increased risk of LCPD. Conclusions: Our results suggest that the IL-6 -174 G > C but not the IL-6 -597 G > C polymorphism may increase LCPD susceptibility in Iranian children.

Association of MTHFR 1298A > C Polymorphism with Susceptibility to Non-Syndromic Cleft Lip with or without Palate: A Case-Control Study and Meta-Analysis.

BACKGROUND: Several studies have evaluated association of the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene 1298A > C polymorphism with non-syndromic cleft lip with or without palate (NSCL ± P) susceptibility, however the results are inconsistent. MATERIALS AND METHODS: To address this issue, we performed a case-control study to evaluate the association of MTHFR 1298A > C polymorphism with NSCL ± P risk, followed by a meta-analysis. RESULTS: Including our study, a total of 22 case-control studies with 2,814 cases and 4,199 controls were selected. The results suggested that there was no significant association between MTHFR 1298A > C polymorphism and NSCL ± P risk overall. The subgroup analysis demonstrated that the polymorphism was significantly associated with NSCL ± P risk in Asians and Iranian populations, but not in Caucasians, mixed and Chinese populations. CONCLUSION: This meta-analysis indicates that MTHFR 1298A > C polymorphism may not contribute to NSCL ± P risk in overall. However, the MTHFR 1298A > C polymorphism was significantly associated with an increased risk of NSCL ± P in Asians and Iranian populations.

Association of REarranged during Transfection (RET) c.73 + 9277T > C and c.135G > a Polymorphisms with Susceptibility to Hirschsprung Disease: A Systematic Review and Meta-Analysis.

Background: Previous studies have suggested a close association between REarranged during Transfection (RET) c.73 + 9277T > C and c.135G > A polymorphisms and Hirschsprung disease (HSCR) susceptibility. The results are inconsistent and contradictory. Thus, we performed a meta-analysis to evaluate the association of RET c.73 + 9277T > C and c.135G > A polymorphisms with risk of HSCR.Methods: The eligible literatures were searched by PubMed, Google Scholar, EMBASE, and CNKI up to August 5 2019.Results: A total of 20 studies including 10 studies with 1136 cases and 2420 controls on c.73 + 9277T > C and 10 studies with 917 cases and 1159 controls on c.135G > A were selected. Pooled ORs revealed that c.73 + 9277T > C and c.135G > A polymorphisms were significantly associated with an increased risk of HSCR. Moreover, stratified analysis revealed that c.73 + 9277T > C and c.135G > A polymorphisms were associated with HSCR risk in Asian, Caucasian and Chinese populations.Conclusions: This meta-analysis result indicated that the RET c.73 + 9277T > C and c.135G > A polymorphisms were associated with susceptibility to HSCR.

Association of eNOS and ACE Polymorphisms with Retinopathy of Prematurity: A Systematic Review and Meta-Analysis.

Background: We performed a meta-analysis to clarify the association of endothelial nitric oxide synthase (eNOS) and angiotensin I-converting enzyme (ACE) gene polymorphisms with retinopathy of prematurity (ROP) risk. Methods: PubMed, Medline, and Embase literatures up to June 01, 2019, were reviewed. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to estimate the strength of associations. Results: Eighteen case-control studies including 14 studies (810 cases and 1754 controls) on eNOS polymorphisms and four studies (1014 cases and 1215 controls) on ACE I/D polymorphism were selected. Overall, analysis showed that infants with the ACE I/D polymorphism have an increased susceptibility to ROP. No association of eNOS 27-bp, 894 G > T and -786 T > C polymorphisms with ROP risk was found. Conclusion: ACE I/D polymorphism may serve as genetic biomarker of increased ROP risk. The eNOS polymorphisms do not appear to influence susceptibility to ROP.

Exploring the main effects of phoenix dactylifera on destructive changes caused by cyclophosphamide in male reproductive system in mice.

Cyclophosphamide leaves an undesirable effect on testes. This study was conducted to explore the effects of the Phoenix dactylifera (DP) on testes following the cyclophosphamide treatment. Thirty-six male mice were divided into six groups, one control, one cyclophosphamide, two groups of cyclophosphamide with a dose of 200 mg kg-1 and a dose of 400 mg kg-1 DP, and two of only high and low doses of DP. All groups were gavaged daily for 28 days. The animals were euthanized 24 hr after implementing the last treatment. Then, the testes and epididymis samples were removed and weighed. The main sperm characteristics such as the number of sperm and sperm viability, the morphometric changes, biochemical analysis of testes and enzyme activity were investigated. With the cyclophosphamide group, only body weight, testes weight, epididymis weight, sperm viability and the fertilization percentage were decreased significantly compared to the control group. Moreover, the spermatogenesis indices and morphometric parameters in this group indicated a significant decrease. Furthermore, the morphological changes were observed in the testicular tissue, including seminiferous tubule atrophy, vacuolation, hyperemia of blood vessels and increased space in the interstitial tissue. In the biochemical study of cyclophosphamide group, the amount of glutathione peroxidase in serum was decreased, whereas, the amount of malondialdehyde in testicular tissue showed a significant increase. The DP group included the antioxidant and anti-apoptotic properties. It seemed that the compounds in the DP would lead to the inhibition of the production of active metabolites released from the cyclophosphamide.

Association of GSTM1, GSTT1, GSTM3, and GSTP1 Genes Polymorphisms with Susceptibility to Osteosarcoma: a Case- Control Study and Meta-Analysis

Background: Some studies have investigated the association of GSTM1, GSTT1, GSTM3, and GSTP1 polymorphisms with susceptibility to osteosarcoma; however, these studies results are inconsistent and inconclusive. In order to drive a more precise estimation, the present case-control study and meta-analysis was performed to investigate association of GSTM1, GSTT1, GSTM3, and GSTP1 polymorphisms with osteosarcoma. Methods: Eligible articles were identified by a search of several electronic databases for the period up to May 5, 2018. Odds ratios were pooled using either fixed-effects or random effects models. Results: Finally, a total of 24 case-control studies with 2,405 osteosarcoma cases and 3,293 controls were included in the present meta-analysis. Overall, significantly increased osteosarcoma risk was found when all studies were pooled into the meta-analysis of GSTT1 (Null vs. Present: OR= 1.247 95% CI 1.020-1.524, P= 0.031) and GSTP1 polymorphism (B vs. A: OR= 8.899 95% CI 2.722-29.094, P≤0.001). In the stratified, significantly increased osteosarcoma risk was observed for GSTT1 polymorphism among Asians (Null vs. Present: OR= 1.300 95% CI 1.034-1.635, P= 0.025), but not among Caucasians. Conclusions: This meta-analysis demonstrated that GSTP1 and GSTT1 null genotype are associated with the risk of osteosarcoma. Future large welldesigned epidemiological studies are warranted to validate our results.

ASSOCIATION OF TNF- α-308G>A POLYMORPHISM WITH SUSCEPTIBILITY TO CELIAC DISEASE: A SYSTEMATIC REVIEW AND META-ANALYSIS.

BACKGROUND: There is increasing evidence to show that TNF-α -308G>A polymorphism may be a risk factor for celiac disease, but the results are inconsistent. OBJECTIVE: Thus, we aimed to perform a meta-analysis involving published studies up to January 2019 to elucidate the association. METHODS: To assess the effect of TNF-α -308G>A polymorphism on celiac disease susceptibility, we searched PubMed, ISI Web of Knowledge, Chinese National Knowledge Infrastructure (CNKI) databases to identify eligible studies, without restriction. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the susceptibility to celiac disease. RESULTS: A total of 11 studies with 1147 cases and 1774 controls were selected for this meta-analysis. The pooled results indicated that TNF-α -308G>A polymorphism was associated with increased risk of celiac disease (A vs G: OR=2.077, 95% CI=1.468-2.939, P=≤0.001; AA vs GG: OR=8.512, 95% CI=3.740-19.373, P=≤0.001; AA+AG vs GG: OR=1.869, 95% CI=1.161-3.008, P=0.010; and AA+AG vs GG: OR=4.773, 95% CI=3.181-7.162, P≤0.001). Subgroup analysis by ethnicity also revealed significant association in Caucasians. In addition, there was a significant association between TNF-α -308G>A polymorphism and celiac disease risk in Italy, Spain and PCR-FRLP group studies. CONCLUSION: Our meta-analysis suggests that the TNF-α -308G>A polymorphism plays an important role in celiac disease susceptibility. However, our results are still needed to strengthen by further studies in different ethnicities and larger sample sizes.

Association of MTHFR 677C>T, 1298A>C and MTR 2756A>G Polymorphisms with Risk of Retinoblastoma.

BACKGROUND: The MTHFR 677C>T, 1298A>C and MTR 2756A>G polymorphisms have been investigated in several different cancer types. However, the role of these polymorphisms in the development of retinoblastoma remains unclear. Here, we have evaluated the association of the MTHFR 677C>T, 1298A>C and MTR 2756A>G polymorphisms with the risk of retinoblastoma in Iranian children. METHODS: The MTHFR 677C>T, 1298A>C and MTR 2756A>G polymorphisms in 66 patients with retinoblastoma and 99 age-and gender-matched healthy controls were detected on the ABI PRISMs 7500 Real-Time PCR System. The association between these polymorphisms and the risk of retinoblastoma was analysed by an odds ratio with a 95% confidence interval. RESULTS: Our results showed a significant association between the MTR 2756A>G polymorphism and the risk of retinoblastoma. In the MTR 2756A>G polymorphism, the AG (39.4%) and GG (9.1%) genotype frequencies in the cases were found to be higher in comparison with the controls, showing a significant difference (p < 0.05). However, no significant difference was observed in the allelic or genotypic frequencies for both the MTHFR 677C>T and 1298A>C polymorphisms in the retinoblastoma patients of the controls (p > 0.05). CONCLUSIONS: Our results suggested that the MTR 2756A>G polymorphism might be associated with an increased risk of retinoblastoma in Iranian children. However, the results show that the MTHFR 677C>T and 1298A>C polymorphisms are not significantly associated with an increased risk of retinoblastoma.

ASSOCIATIONS OF IL-6 -174G>C AND IL-10 -1082A>G POLYMORPHISMS WITH SUSCEPTIBILITY TO CELIAC DISEASE: EVIDENCE FROM A META-ANALYSIS AND LITERATURE REVIEW.

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.

Association of MTHFR 677C>T Polymorphism with Susceptibility to Ovarian and Cervical Cancers: A Systematic Review and Meta-Analysis.

Background: Previous studies have evaluated the impact of MTHFR 677C>T polymorphism on susceptibility to ovarian and cervical cancers in women, but the conclusions are still controversial. To get a more precise evaluation of the association between MTHFR 677C>T polymorphism and risk of ovarian and cervical cancers, we performed a meta-analysis of the association of all eligible studies. Methods: A comprehensive search performed in PubMed, Google Scholar, CNKI, and Web of Science databases to identify the relevant studies up to October 15, 2018. The strength of the association was estimated by odds ratios (OR) with 95% confidence interval (CI). Results: A total of 27 case-control studies including eleven studies with 4990 cases 7730 controls on ovarian cancer and 16 studies with 4990 cases and 7730 controls on cervical cancer were selected. Pooled data revealed that the MTHFR 677C>T polymorphism not significantly associated with an increased risk of ovarian and cervical cancers under all five genetic models. However, stratified analysis by ethnicity showed that the MTHFR 677C>T polymorphism was significantly associated with risk of ovarian cancer in Asians. No publication bias was found in the current meta-analysis. Conclusions: The results of this meta-analysis proposes that the MTHFR 677C>T polymorphism may not play a role in development of ovarian and cervical cancers in overall population. Further well-designed studies are necessary to clarify the precise role of the MTHFR 677C>T polymorphism on ovarian and cervical cancers risk.

Association of Promoter Region Polymorphisms of IL-10 Gene with Susceptibility to Lung Cancer: Systematic Review and Meta-Analysis.

Objective: Epidemiological studies have suggested that the promoter region polymorphisms of interleukin-10 (IL-10) gene may be associated with an increased risk of lung cancer. However, those studies results are controversial. Thus, a comprehensive meta-analysis was performed to evaluate the association of promoter region polymorphisms of IL-10 gene with susceptibility to lung cancer. Methods: a comprehensive search of PubMed, EMBASE, and CNKI databases was performed to find all eligible studies up to September 15, 2018. The pooled odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of such association. Results: A total number of 19 case-control studies with 4084 cases and 6,131 controls were selected. The overall meta-analysis results showed that the -592A>C polymorphism was significantly associated with lung cancer risk under four genetic models, i.e., allele (CT vs. TT: OR= 1.17, 95% CI 1.01-1.35, p=0.02), homozygote (CC vs. AA: OR= 1.64, 95% CI 1.29-2.02, p≤0.001), heterozygote (CA vs. AA: OR= 1.26, 95% CI 1.06-1.50, p≤0.001), and dominant (CC+CA vs. AA: OR= 1.31, 95% CI 1.11-1.54, p=0.001). However, there was no significant association between -819T>C and -1082A>G polymorphisms of IL-10 and lung cancer risk. Similarly, subgroup analyses by ethnicity detected significant association between IL-10 -592A>C and lung cancer among Asians and Caucasians. Conclusions: Our meta-analysis suggests that the IL-10 -592A>C polymorphism might be risk factor for lung cancer, especially among Asian and Caucasians. In contrast, the IL-10 -819T>C and -1082A>G polymorphisms are not significantly associated with increased risk of lung cancer.

Association of MTHFR 677C>T and 1298A>C polymorphisms with susceptibility to autism: A systematic review and meta-analysis.

Several studies have investigated association of MTHFR 677C > T and 1298A > C polymorphisms with risk of autism, but they have reported controversial and inconclusive results. The present meta-analysis was designed to evaluate association of MTHFR 677C > T and 1298A > C polymorphisms with risk of autism. A comprehensive literature search was done in PubMed, EMBASE, and CNKI databases to identify all eligible publications up to April 01, 2019. Finally, 25 case-control studies including 18 studies on MTHFR 677C > T and 7 studies on MTHFR 1298A > C polymorphism were selected. Overall, a significant association was found between MTHFR 677C > T and an increased risk of autism under all five genetic models (T vs. C: OR = 1.483, 95% CI 1.188-1.850, p ≤ 0.001; TT vs. CC: OR = 1.834, 95% CI 1.155-2.913, p = 0.010; TC vs. CC: OR = 1.512, 95% CI 1.101-2.078, p = 0.011; TT + TC vs. CC: OR = 1.632, 95% CI 1.261-2.113, p ≤ 0.001; and TT vs. TC + CC: OR = 1.427, 95% CI 1.002-2.032, p = 0.049). However, no significant association was found between MTHFR 1298A > C and autism risk. Stratified analyses showed that MTHFR 677C > T and 1298A > C polymorphisms are involved in genetic susceptibility of autism by ethnicity. Results of this meta-analysis indicated that MTHFR 677C > T polymorphism may be associated with increased risk of autism in overall and by ethnicity, while MTHFR 1298A > C was reported to be significantly associated with the risk of autism only in Caucasians. MTHFR polymorphisms could be used as a diagnostic marker for autism with respect to ethnicity background.

RESUMO CONTEXTO: Há evidências crescentes para mostrar que o TNF-α-308G>A polimorfismo pode ser um fator de risco para a doença celíaca, mas os resultados são inconsistentes. OBJETIVO: Por isto objetivou-se realizar uma meta-análise envolvendo estudos publicados até janeiro de 2019 para elucidar esta associação. MÉTODOS: Para avaliar o efeito do TNF-α-308G>A polimorfismo na suscetibilidade da doença celíaca, pesquisou-se os bancos de dados do PubMed, ISI Web of Knowledge e Chinese National Knowledge Infrastructure (CNKI) para identificar estudos elegíveis, sem restrições. Para avaliar a suscetibilidade à doença celíaca, foram utilizadas os odds ratio sumários (ORs) e os intervalos de confiança de 95% (ICs). RESULTADOS: Um total de 11 estudos com 1147 casos e 1774 controles foram selecionados para esta meta-análise. Os resultados agrupados indicaram que o TNF-α-308G>A polimorfismo associou-se ao aumento do risco de doença celíaca (A vs G: OR=2,077; 95% IC=1,468-2,939; P=≤0,001; AA vs GG: OR=8,512; 95% IC=3,740-19,373; P=≤0,001; AA+AG vs GG: OR=1,869; 95% IC=1,161-3,008; P=0,010; e AA+AG vs GG: OR=4,773; 95% IC=3,181-7,162; P≤0,001). A análise de subgrupos por etnia também revelou associação significativa em caucasianos. Além, havia uma associação significativa entre o TNF-α-308G>A um polimorfismo e o risco do doença celíaca na Italia, na Espanha e em estudos do grupo do PCR-FRLP. CONCLUSÃO: Nossa meta-análise sugere que o TNF-α-308G>A polimorfismo desempenha um papel importante na suscetibilidade da doença celíaca. No entanto, nossos resultados necessitam de mais dados e de serem fortalecidos por outros estudos em diferentes etnias e tamanhos amostrais maiores.

RESUMO CONTEXTO: Há poucas evidências para sugerir que os IL-6 -174G>C e IL-10 -1082A>G polimorfismos são significativamente associados com susceptibilidade para doença celíaca. Assim, foi realizada a presente meta-análise para explorar a potencial associação entre estes polimorfismos com o risco de doença celíaca. MÉTODOS: Foram pesquisados estudos elegíveis no Pubmed, Medline, Embase, Web of Science e CNKI Database até abril de 2019. Razões de probabilidades com 95% de intervalo de confiança foram calculados para avaliar as potenciais associações. Além disso, observou-se a heterogeneidade, a sensibilidade e o viés de publicação para esclarecer e validar os resultados agrupados. RESULTADOS: No total, nove estudos caso-controle envolvendo cinco estudos com 737 casos e 1.338 controle em IL-6 -174G>C polimorfismo e quatro estudos com 923 casos e 864 controles em IL-10 -1082A>G polimorfismo foram selecionados. As razões de probabilidade mostraram que o IL-6 -174G>C e IL-10 -1082A>G polimorfismos não estavam significativamente associados com aumento risco de doença celíaca nos cinco modelos genéticos. Não foi detectado viés de publicação. CONCLUSÃO: Pelo nosso conhecimento esta é a primeira meta-análise resumindo todos estudos disponíveis para associação de IL-6 -174G>C e IL-10 -1082A>G polimorfismos com doença celíaca. Estes resultados sugerem que os IL-6 -174G>C e IL-10 -1082A>G polimorfismos podem não ser associados com aumento risco de doença celíaca. Além disso, maiores estudos e mais bem desenhados são necessários para descrever totalmente a associação de IL-6 -174G>C e IL-10 -1082A>G polimorfismos com doença celíaca.
