Résumé
ObjectiveTo investigate the value of serum Fetuin-A and Fetuin-B combined with Homeostasis Model Assessment of Insulin Resistance （HOMA-IR） in predicting nonalcoholic fatty liver disease （NAFLD）. MethodsA total of 120 patients with NAFLD who attended Department of Gastroenterology， The First Affiliated Hospital of Dali University， from June 2020 to June 2021， and 120 healthy individuals who underwent physical examination at Physical Examination Center during the same period of time were enrolled as subjects， and clinical data were collected from all subjects. The serum levels of Fetuin-A and Fetuin-B were measured. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups； the multivariate Logistic regression analysis was used to assess the risk factors for NAFLD. The receiver operating characteristic （ROC） curve was plotted to evaluate the predictive efficacy of Fetuin-A and Fetuin-B combined with HOMA-IR in NAFLD patients. ResultsCompared with the healthy control group， the NAFLD group had significantly higher levels of body mass index， systolic blood pressure， diastolic blood pressure， alanine aminotransferase， aspartate aminotransferase， fasting blood glucose， fasting insulin， triglycerides， HOMA-IR， Fetuin-A， and Fetuin-B （all P<0.05）. The multivariate Logistic regression analysis showed that Fetuin-A （odds ratio ［OR］=1.010， 95% confidence interval ［CI］： 1.001 — 1.020， P<0.05）， Fetuin-B （OR=1.113， 95%CI： 1.021 — 1.214， P<0.05）， and HOMA-IR （OR=24.053， 95%CI： 2.624 — 220.470， P<0.05） were independent risk factors for NAFLD. The ROC curve analysis showed that Fetuin-A， Fetuin-B or HOMA-IR alone had an area under the ROC curve （AUC） of 0.637 （95%CI： 0.551 — 0.722）， 0.853 （95%CI： 0.796 — 0.912）， and 0.837 （95%CI： 0.763 — 0.912）， respectively， and Fetuin-A combined with Fetuin-B， Fetuin-A combined with HOMA-IR， and Fetuin-B combined with HOMA-IR had an AUC of 0.853 （95%CI： 0.795 — 0.911）， 0.843 （95%CI： 0.770 — 0.916）， 0.922 （95%CI： 0.877 — 0.967）， respectively， while the combination of these three indicators had an AUC of 0.922 （95%CI： 0.877 — 0.966）. ConclusionFetuin-A and Fetuin-B have a certain value in predicting NAFLD， and Fetuin-B combined with HOMA-IR tends to have a higher predictive value.
Résumé
Objective To investigate the independent association of serum Fetuin-B with metabolic syndrome in obese Chinese adults.Methods Cross-sectional data on socio-demographic,lifestyle,clinical characteristics, and serum Fetuin-B were collected for 1 318 Chinese adults with central obesity.Associations of serum Fetuin-B with metabolic syndrome and insulin resistance were analyzed using multivariable Logistic regression analysis.Results A total of 820(62.2%)individuals were identified as metabolic syndrome.Subjects with metabolic syndrome showed significantly increased levels of serum Fetuin-B than those with non-metabolic syndrome[(4.18 ±1.39 vs 4.02 ± 1.35)μg/ml,P=0.043].Increased serum Fetuin-B were significantly associated with increased fasting plasma glucose and insulin levels, as well as prevalences of non-alcoholic fatty liver disease(NAFLD)and insulin resistance.After adjustment for potential confounders, serum Fetuin-B was significantly associated with increased risks of metabolic syndrome and insulin resistance(OR=1.19,95%CI 1.06-1.34,P=0.004;OR=1.15,95%CI 1.01-1.30,P=0.031 respectively).Conclusion Serum Fetuin-B level was significantly associated with NAFLD;and elevated serum Fetuin-B was significantly associated with increased risk of metabolic syndrome.
