The role of IL22 polymorphisms on liver cirrhosis in patients with hepatitis B virus: A case control study.

ABSTRACT: AIMS:Interleukin(IL)-22 plays an important role in promoting liver regeneration and repair, but its role in chronic HBV-related liver diseasesis not clear. The goal of this study was to evaluate associations between eight IL22 single nucleotide polymorphisms (SNPs) and the development of chronic HBV cirrhosis and HBV-related HCC within a Chinese Han population. METHODS:We investigated associations between single nucleotide polymorphisms (SNPs) in the IL22 gene (rs1026788, rs2227472, rs2227491, rs2227485, rs1179249, rs2046068,rs2227473, and rs7314777) and the risk of HBV-related chronic liver diseases within a Han population in Northeast China. A total of 649 participants were included in the study, including 103 patients with CHB, 264 patients with LC, and 282 patients with HCC. The odds ratios (OR) and corresponding 95% confidence intervals (CI) were calculated using chi-square test. Haplotype analysis was conducted by haploview software. RESULTS:Genotype and allele distributions of SNPs rs1179249 and rs2227472 differed between LC and CHB groups (both P < 0.05).The G alleles of SNP rs2227491 and rs1026788 were more frequent in the LC group than in the CHB group (P = 0.046, P = 0.041 respectively). A IL22 haplotype consisting of the minor alleles of SNP rs1179249 and the major alleles of seven other SNPs occurred less frequently in the LC and HCC groups than in the CHB group (28.2%, 33.94%, and 37.86%, respectively, P < 0.05). Moreover, there were no significant associations between smoking or drinking and IL22 SNPs on the risk of HCC (P > 0.05). CONCLUSION:IL22 genetic variations were associated with chronic HBV infection progression, especially in the HBV-LC group. The IL22 genetic variations may help clinicians initiate the correct treatment strategy at the CHB stage.

Project description:Reactive oxygen species (ROS) play critical roles in hepatocarcinogenesis. The catalase (CAT) enzyme is involved in the repair of ROS. Therefore, we investigate the association between CAT gene polymorphisms and the risk of hepatocellular carcinoma (HCC). A total of 715 subjects were divided into 4 groups: 111 chronic hepatitis B (CHB) patients, 90 hepatitis B virus (HBV)-related liver cirrhosis (LC) patients, 266 HBV-HCC patients, and 248 healthy controls. The polymerase chain reaction-restriction fragment length polymorphism strategy was used to detect CAT gene rs1001179, rs769217, and rs7943316 polymorphisms. Binary logistic regression analyses adjusting for sex, age, ethnicity, smoking and alcohol consumption, and body mass index suggested that subjects carrying the rs769217 T allele were at marginally increased risk of CHB, LC, and HCC, with adjusted odds ratios (ORs) of 1.51 (95% confidence interval [CI] = 1.04-2.20, P = 0.029), 1.48 (95% CI = 1.03-2.14, P = 0.035), and 1.51 (95% CI = 1.14-1.98, P = 0.004), respectively. Similarly, those individuals carrying the rs769217 TT genotype had a moderately increased risk of CHB, LC, and HCC, with adjusted ORs of 2.11 (95% CI = 1.05-4.22, P = 0.035), 2.00 (95% CI, 1.01-3.95, P = 0.047), and 1.93 (95% CI = 1.14-3.28, P = 0.015), respectively. Moreover, subjects carrying the rs769217 CT genotype and at least 1 copy of the T allele (dominant model) were 1.78 times and 1.83 times more likely to develop HCC, respectively (OR = 1.78, 95% CI = 1.16-2.73, P = 0.009 and OR = 1.83, 95% CI = 1.23-2.71, P = 0.003). This association between CAT rs769217 T alleles and HCC risk is significantly strengthened among men, nonsmokers, nondrinkers, and among individuals <50 years of age. Furthermore, we found 1 high-risk haplotype GTA for CHB (OR = 1.45, 95% CI = 1.05-2.01) and 1 protective haplotype GCA for HCC risk (OR = 0.67, 95% CI = 0.52-0.87). We did not found any significant difference in CAT rs1001179 and rs7943316 polymorphisms between controls and cases. Our findings suggest that the CAT rs769217 T allele is associated with increased risk of CHB, HBV-LC, and HBV-HCC in Guangxi population.

Project description:BackgroundWe aimed to describe the characteristics and outcomes in pregnant women with liver cirrhosis, and identify the predictors of adverse events of mother and fetus.MethodsRetrospectively collected mothers with liver cirrhosis in our center from 6/2010 to 6/2019. Women without liver cirrhosis were selected as a control in a 1:2 ratio. The primary assessment was the frequency of maternal and fetal adverse events. The secondary assessment was the adverse events in patients continuing pregnancy or not and the factors to predict the severe adverse events.ResultsOf 126 pregnancies enrolled, 29 pregnancies were terminated for worrying disease progression and 97 pregnancies continued. One hundred ninety-four pregnancies without liver cirrhosis were selected as control. At baseline, patients with liver cirrhosis have a lower level of platelet, hemoglobin, prothrombin activity, and a higher level of ALT, total Bilirubin, creatinine. Compared to control, patients with liver cirrhosis had a higher frequency of adverse events, including bleeding gums (7.2%vs. 1.0%), TBA elevation (18.6%vs.3.1%), infection (10.3%vs.0.5%), cesarean section (73.6%vs.49.5%), postpartum hemorrhage (13.8% vs 2.1%), blood transfusion (28.9% vs 2.1%), new ascites or aggravating ascites (6.2% vs.0%), MODS (7.2% vs.0.5%) and intensive care unit admissions (24.1% vs 1.1%). The incidence of severe maternal adverse events was also higher (32.0% vs 1.5%). Women who chose to terminated the pregnancy had less severe adverse events (3.4% vs.32.0%). A higher frequency of fetal/infants' complications was observed in liver cirrhosis population than control, including newborn asphyxia (10.2% vs1.1%), low birth weight infant (13.6% vs. 2.6%). In patients who progressed into the third trimester, multivariable regression analysis demonstrated that severe adverse events were associated with a higher CTP score (OR 2.128, 95% CI [1.002, 4.521], p = 0.049). Wilson's disease related liver cirrhosis has a better prognosis (OR = 0.009, 95% CI [0, 0.763], p = 0.038).ConclusionsThe incidence of the adverse events was significantly increased in pregnancies complicated by cirrhosis. The predictor of severe adverse events is higher CTP score. Wilson's disease induced liver cirrhosis have a better prognosis. Timely termination of pregnancy during the first trimester may avoid the incidence of severe adverse events.
