Globally, tuberculosis is the second-leading cause of infectious diseases. This has become a significant world-wide social and public health issue, and one of the major diseases in China. In addition to environmental risk factors, genetic factors may play an important role in the development of tuberculosis.Methods: We conducted a case-control study to evaluate the genetic effects of functional single nucleotide polymorphisms (SNPs): MBL2 rs1800450 C > T, MBL2 rs7095891 G > A and MBL2 rs7096206 C > G, and their influences on the development of tuberculosis. A total of 231 tuberculosis cases and 240 controls were included in this study. Genotypes were determined using a custom-designed 48-Plex SNPscanTM kit.Results: The MBL2 rs7095891 G > A polymorphism was associated with an increased risk of TB. However, there were no significant links with the other two SNPs. In any subgroup, there was no relvant risk of TB associated with MBL2 rs7095891 G > A polymorphism.Conclusion: These findings suggest that functional polymorphism MBL2 rs7095891 G > A may be positively correlated with susceptibility to tuberculosis. These findings may be somewhat limited by sample size. A further study with more focus on different regions, ethnic groups and larger sample sizes is therefore suggested.","PeriodicalId":73460,"journal":{"name":"International journal of molecular epidemiology and genetics","volume":"9 5","pages":"64-70"},"PeriodicalIF":0.0,"publicationDate":"2018-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6261923/pdf/ijmeg0009-0064.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36752215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aims of this study were to determine the prevalence of steatosis in CHB patients among Filipinos; determine the factors related to the presence of steatosis among individuals with and without CHB infection; and to investigate the possible association between steatosis and polymorphism in interleukin 28B (IL28B) gene. The presence of steatosis was correlated with clinical, biochemical and histological parameters. Peripheral blood samples of CHB patients with steatosis, CHB patients without steatosis and normal controls were genotyped for IL28B rs8099917 T>G using the TaqMan assay. Of the 46 CHB patients, 41% (19/46) had steatosis. Body mass index (BMI), fasting blood sugar (FBS), lipid profile and alanine transaminase levels were observed to be significantly different between CHB patients with steatosis and normal controls. The serum FBS of CHB patients with steatosis was significantly higher than patients without steatosis. High density lipoprotein cholesterol of patients without steatosis was significantly higher than patients with steatosis. Although not statistically significant, BMI, triglycerides, low density lipoprotein cholesterol and histology activity index in CHB patients with steatosis were found to be higher than those without steatosis. There was no significant association between the stage of fibrosis and severity of steatosis. In conclusion, the prevalence of hepatic steatosis among Filipino patients with CHB is 41%.
