AIM
The association between glycemia and liver fibrosis was analyzed using hemoglobin A1c (HbA1c) and the Fibrosis-4 (FIB-4) index in a large general population cohort that underwent a health checkup.
METHODS
A total of 6927 subjects without hepatitis B or C virus infection or habitual alcohol intake were enrolled. Non-alcoholic fatty liver disease (NAFLD) was diagnosed by ultrasonography and potential liver fibrosis (FIB-4 index ≥1.3) in NAFLD was analyzed in relation to HbA1c level. Factors associated with potential liver fibrosis of NAFLD were also analyzed.
RESULTS
The overall frequency of NAFLD was 27.9% (1935 subjects) and the frequency of NAFLD by HbA1c level (<4.9%, 5.0-5.9%, 6.0-6.9%, 7.0-7.9%, ≥8.0%) was 16%, 27%, 54%, 53%, and 54%, respectively. Among the 1935 NAFLD cases, the frequency of potential liver fibrosis was 25.2% (487 subjects) overall and 19%, 22%, 30%, 52%, and 31%, respectively, by HbA1c category. From multivariate analysis, an HbA1c level ≥6.5% was significantly associated with potential liver fibrosis (P = 0.017, hazard ratio = 1.7).
CONCLUSIONS
The prevalence of NAFLD and liver fibrosis of NAFLD increased according to glycemia, up to 8.0% HbA1c. Measuring HbA1c and calculating the FIB-4 index in health checkups could help to identify potential cases of liver fibrosis of NAFLD, which should then be further evaluated using other techniques to confirm liver fibrosis.
目的
在接受健康检查的大型普通人群队列中，使用糖化血红蛋白（HbA1c）和纤维化-4（FIB-4）指数分析血糖与肝纤维化之间的关联。
方法
共纳入6927名无乙型或丙型肝炎病毒感染或习惯性饮酒的受试者。通过超声诊断非酒精性脂肪性肝病（NAFLD），并分析NAFLD中潜在肝纤维化（FIB-4指数≥1.3）与HbA1c水平的关系。还分析了与NAFLD潜在肝纤维化相关的因素。
结果
NAFLD的总体发生率为27.9%（1935名受试者），按HbA1c水平（<4.9%、5.0-5.9%、6.0-6.9%、7.0-7.9%、≥8.0%）划分的NAFLD发生率分别为16%、27%、54%、53%和54%。在1935例NAFLD病例中，潜在肝纤维化的总体发生率为25.2%（487名受试者），按HbA1c类别划分分别为19%、22%、30%、52%和31%。多因素分析显示，HbA1c水平≥6.5%与潜在肝纤维化显著相关（P = 0.017，风险比 = 1.7）。
结论
NAFLD及NAFLD肝纤维化的患病率随血糖升高而增加，直至HbA1c达到8.0%。在健康检查中检测HbA1c并计算FIB-4指数有助于识别NAFLD潜在肝纤维化病例，然后应使用其他技术进一步评估以确认肝纤维化。
