Background: Dysbiosis of the gut microbiota has been considered to have a role in nonalcoholic fatty liver disease (NAFLD) progression. However, there is still lack of studies regarding this phenomenon. Aim: To find the difference in the proportion of gut microbiota in NAFLD patients based on the stages of liver fibrosis. Patients and Methods: A cross-sectional study was conducted at Dr. Cipto Mangunkusumo Hospital, which is the largest tertiary referral center. Human fecal samples from NAFLD patients who came to the outpatient clinic were collected consecutively. The stool sample examination was performed using an isolation DNA kit (Tiangen) and quantitative real-time polymerase chain reaction (Fast 7500). Clinical and laboratory data were also collected. The stage of fibrosis was diagnosed based on transient elastography (FibroScan® 502 Touch; Echosens, France). Results: Of 60 NAFLD human fecal samples, 35 patients had nonsignificant fibrosis and 25 patients had significant fibrosis (46.7% male and 53.3% female; median age 56 years). Most patients had diabetes (85%), dyslipidemia (58.3%), obesity (58.3%), and central obesity (90%). The proportion of Bacteroides was higher when compared to Lactobacillus and Bifidobacteria. Of these 3 microbiota, the proportion of Bacteroides was significantly higher in the significant fibrosis group when compared to the nonsignificant fibrosis group. Conclusion: There is a change in the composition of gut microbiota in NAFLD patients. The proportion of Bacteroides is significantly higher in significant liver fibrosis, which may play a role in NAFLD progression.

We assessed the relationship between serum alkaline phosphatase (ALP) and liver fibrosis by histology, in addition to other noninvasive parameters, in obese patients undergoing metabolic surgery. Patients scheduled for elective bariatric surgery were prospectively recruited from a bariatric clinic. An intraoperative liver biopsy was performed, and liver histology was evaluated by a pathologist blinded to the patients’ data. The endpoint was significant fibrosis defined as fibrosis stage ≥ 2. Independent predictors of fibrosis were identified by logistic regression. Two hundred ten patients were recruited. Liver histology revealed steatosis in 87.1%, steatohepatitis in 21.9%, and significant fibrosis in 10%. Independent predictors of significant fibrosis were ALP (Odds Ratio (OR) 1.03; 95% Confidence interval (CI), 1.01–1.05), alanine aminotransferase (OR 1.02; 95% CI, 1.01–1.03), HbA1c (OR 1.58; 95% CI, 1.20–2.09), and body mass index (OR 1.06; 95% CI, 1.00–1.13). A tree-based model was developed to predict significant fibrosis, with a receiver operating characteristic (ROC) area of 0.845, sensitivity of 0.857, specificity of 0.836, and accuracy of 0.931. The applicability of serum ALP as an independent biomarker of liver fibrosis should be considered in obesity surgery patients, and in the broader context of obese patients with nonalcoholic fatty liver disease.

Background and Aims: Nonalcoholic fatty liver disease (NAFLD) and sarcopenic obesity share several pathophysiologic backgrounds. No prior studies have determined a plausible association between sarcopenic obesity and NAFLD and NAFLD-associated fibrosis. We aim to investigate the association between sarcopenic obesity and NAFLD, and NAFLD-associated fibrosis detected by transient elastography. Methods: In a cross-sectional study from the 2017-2018 National Health and Nutrition Examination Survey, 1,925 participants were identified. NAFLD was defined by controlled attenuation parameter (CAP) scores and significant fibrosis (≥F2)/cirrhosis by liver stiffness measurements on transient elastography. Sarcopenic obesity was defined by appendicular lean mass and body fat. Results: Individuals with sarcopenic obesity had a significantly higher odds of having NAFLD [CAP score ≥263 dB/m, odds ratio (OR): 2.88, 95% confidence interval (CI): 1.82-4.57, and CAP score ≥285, OR: 3.71, 95%CI: 2.24-6.14] after adjusting for age, gender, and race/ethnicity. The association remained statistically significant after adjustment for socioeconomic status, lifestyle and behavioral risk factors, and metabolic conditions (CAP score ≥263, OR: 2.61, 95%CI: 1.51-4.50, and CAP score ≥285, OR: 3.31, 95%CI: 1.85-5.96). Sarcopenic obesity was also associated with higher odds of having NAFLD-associated significant fibrosis (OR 2.22, 95% CI: 1.03-4.80) in the multivariate model. While those with sarcopenic obesity had a higher prevalence of NAFLD-associated cirrhosis, this association did not reach statistical significance. Conclusions: Sarcopenic obesity was independently associated with an increased risk of NAFLD and NAFLD- associated significant fibrosis independent of well-defined risk factors. Targeted interventions to improve sarcopenic obesity may reduce the risk of NAFLD and NAFLD-associated siginificant fibrosis.

Objective. We aimed at analyzing the role of smoking in hepatic fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) and at exploring the related risk factors. Methods. This was a cross-sectional study that included a total of 225 patients with NAFLD. Among them, 127 were nonsmokers and 98 were smokers. Liver significant fibrosis was diagnosed when the liver stiffness (LS) value was higher than 7.4 kPa. The diagnostic criterion for NAFLD was a controlled attenuation parameter (CAP) value of >238 dB/m. The CAP and LS values were measured using FibroScan. Results. FibroScan showed that the LS value in the smokers was significantly higher than that in the nonsmokers (10.12 ± 10.38 kPa vs. 7.26 ± 6.42 kPa, P=0.013). The proportions of patients with liver significant fibrosis and advanced liver fibrosis among the smokers were significantly higher than those among the nonsmokers (P=0.046). Univariate analysis showed that age, weight, high AST level, low PLT level, and smoking were the risk factors associated with liver fibrosis in the smokers with NAFLD while multivariate analysis showed that age (OR = 1.029, P=0.021), high AST level (OR = 1.0121, P=0.025), and smoking (OR = 1.294, P=0.015) were the independent risk factors associated with liver fibrosis in the patients with NAFLD. Moreover, high AST level (OR = 1.040, P=0.029), smoking index (OR = 1.220, P=0.019), and diabetes mellitus (OR = 1.054, P=0.032) were the independent risk factors for liver fibrosis among the smokers with NAFLD. Conclusion. This study showed that smoking was closely associated with liver fibrosis among the patients with NAFLD. For patients with NAFLD who smoke, priority screening and timely intervention should be provided if they are at risk of liver fibrosis.
