Inflammatory Conditions

Background. Obesity is characterized by liver steatosis, chronic inflammation, and increased liver enzymes, that is, gamma-glutamyltransferase (GGT) and alanine aminotransferase (ALT), markers for nonalcoholic fatty liver disease (NAFLD) and liver fat content. Increased platelet counts (PCs) are associated with inflammatory conditions and are a valuable biomarker of the degree of fibrosis in NAFLD. We investigated alterations in PC, GGT, and ALT after biliopancreatic diversion with duodenal switch (BPD-DS) and Roux-en-Y gastric bypass (RYGBP).Methods. Ten morbidly obese patients (body mass index, BMI:53.5±3.8 kg/m2) who underwent BPD-DS were evaluated preoperatively (baseline) and 1 year (1st followup) and 3 years (2nd followup) after surgery and compared with 21 morbidly obese patients (BMI:42.3±5.2 kg/m2) who underwent RYGBP.Results. Over the 3 years of followup, changes in BPD-DS and RYGBP patients (BPD-DS/RYGBP) were as follows: BMI (−44%/−24%), GGT (−63%/−52%), and ALT (−48%/−62%). PC decreased (−21%) statistically significantly only in BPD-DS patients.Conclusions. Morbidly obese patients treated by RYGBP or BPD-DS show sustained reductions in BMI, ALT, and GGT. The decrease in PC and liver enzymes after BPD-DS may reflect a more pronounced decrease of liver-fat-content-related inflammation and, as a result, a lowered secondary thrombocytosis.

The Relationship

Abstract Background Lipocalin-2 (LCN2) has a critical effect on obesity as well as its associated comorbidities. The present study focused on analyzing serum LCN2 levels of obese patients with nonalcoholic fatty liver disease (NAFLD) and on determining relationship of hepatic steatosis improvement with LCN2 levels after laparoscopic sleeve gastrectomy (LSG). Methods This work enrolled ninety patients with obesity and NAFLD. Twenty-three of them underwent LSG. Anthropometric and biochemical parameters and serum LCN2 levels were determined at baseline and those at 6-month post-LSG. Controlled attenuation parameter (CAP) measured by FibroScan was adopted for evaluating hepatic steatosis. Results Among severe obesity patients, serum LCN2 levels were significantly increased (111.59 ± 51.16 ng/mL vs. 92.68 ± 32.68 ng/mL, P = 0.035). The CAP value was higher indicating higher liver fat content (360.51 ± 45.14 dB/m vs. 340.78 ± 45.02 dB/m, P = 0.044). With regard to surgical patients, liver function, glucose, and lipid levels were significantly improved after surgery. Serum LCN2 levels significantly decreased (119.74 ± 36.15 ng/mL vs. 87.38 ± 51.65 ng/mL, P = 0.001). Decreased CAP indicated a significant decrease in liver fat content (358.48 ± 46.13 dB/m vs. 260.83 ± 69.64 dB/m, P < 0.001). The decrease in LCN2 levels was significantly related to the reduced hepatic fat content and improvement in steatosis grade after adjusting for gender, age, and BMI decrease. Conclusions Serum LCN2 levels are related to obesity and NAFLD. The decreased serum LCN2 levels could be an indicator of hepatic steatosis improvement.

Nonalcoholic fatty liver (NAFL) is a common comorbidity in patients with type 2 diabetes and links to the risk of coronary syndromes. The aim was to determine the manifestations of metabolic syndrome in different organs in patients with liver steatosis. We studied 55 type 2 diabetic patients with coronary artery disease using positron emission tomography. Myocardial perfusion was measured with [15O]H2O and myocardial and skeletal muscle glucose uptake with 2-deoxy-2-[18F]fluoro-d-glucose during hyperinsulinemic euglycemia. Liver fat content was determined by magnetic resonance proton spectroscopy. Patients were divided on the basis of their median (8%) into two groups with low (4.6 ± 2.0%) and high (17.4 ± 8.0%) liver fat content. The groups were well matched for age, BMI, and fasting plasma glucose. In addition to insulin resistance at the whole body level ( P = 0.012) and muscle ( P = 0.002), the high liver fat group had lower insulin-stimulated myocardial glucose uptake ( P = 0.040) and glucose extraction rate ( P = 0.0006) compared with the low liver fat group. In multiple regression analysis, liver fat content was the most significant explanatory variable for myocardial insulin resistance. In addition, the high liver fat group had increased concentrations of high sensitivity C-reactive protein, soluble forms of E-selectin, vascular adhesion protein-1, and intercellular adhesion molecule-1 ( P < 0.05) and lower coronary flow reserve ( P = 0.02) compared with the low liver fat group. In conclusion, in patients with type 2 diabetes and coronary artery disease, liver fat content is a novel independent indicator of myocardial insulin resistance and reduced coronary functional capacity. Further studies will reveal the effect of hepatic fat reduction on myocardial metabolism and coronary function.

Background and aims: Non-alcoholic fatty liver disease (NAFLD), which is associated with fat accumulation and deposition in liver cells, is a serious risk factor for other diseases such as cardiovascular disorders and diabetes. The aim of this study was to investigate the effect of Pilates training on hepatic fat content and liver enzymes in men with NAFLD in 2019. Methods: In this semi-experimental study, 20 men with NAFLD were randomly divided into Pilates training (n=10) and control (n=10) groups. The Pilates group participated in the Pilates training program for eight weeks (three 60-minute sessions per week), whereas the control group engaged in no regular physical activity. The body composition, anthropometric indices, liver fat content, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP) were measured before and after the training period. Eventually, data were analyzed using paired and independent t tests at a significance level of 0.05 by SPSS 18. Results: After eight weeks of Pilates training, liver fat content in the Pilates group was significantly lower than that in the control group (P=0.001). Further, the serum levels of ALT, AST, and ALP significantly decreased in the Pilates group compared to the control group (P=0.04, P=0.05, and P=0.02, respectively). In addition, eight weeks of Pilates training significantly reduced body weight, body mass index (BMI), fat percentage, and the waist-to-hip ratio of patients, while no significant changes were observed in the control group. Conclusion: The results of the present study indicated that Pilates training could be effective in improving liver fat content and reducing the serum levels of ALT, AST, and ALP in men with NAFLD. Furthermore, Pilates training helps to improve body composition and anthropometric indices in patients afflicted with NAFLD and can have a role in the management of this condition.

Underlying Mechanisms

Objective Chemerin and adiponectin are adipokines assumed to be involved in the development of metabolic syndrome-related phenotypes like hepatic steatosis. We aimed to evaluate the associations of circulating chemerin and adiponectin concentrations with liver enzymes, liver fat content, and hepatic steatosis in the general population. Methods Data of 3951 subjects from the population-based Study of Health in Pomerania (SHIP-TREND) were used. Hepatic steatosis was assumed when either a hyperechogenic liver (assessed via ultrasound) or a magnetic resonance imaging (MRI)-quantified liver fat content >5% was present. Adjusted sex-specific quantile and logistic regression models were applied to analyze the associations of chemerin and adiponectin with liver enzymes, liver fat content and hepatic steatosis. Results The observed associations of chemerin and adiponectin with liver enzymes were very divergent depending on sex, fasting status and the specific enzyme. More consistent results were seen in the analyses of these adipokines in relation to MRI-quantified liver fat content. Here, we observed inverse associations to adiponectin in both sexes as well as a positive (men) or U-shaped (women) association to chemerin. Similarly, the MRI-based definition of hepatic steatosis revealed strongly consistent results: in both sexes, high chemerin concentrations were associated with higher odds of hepatic steatosis, whereas high adiponectin concentrations were associated with lower odds. Conclusion Our results suggest a role of these adipokines in the pathogenesis of hepatic steatosis independent of metabolic or inflammatory disorders. However, experimental studies are needed to further clarify the underlying mechanisms and the inter-play between adipokine concentrations and hepatic steatosis.

Nonalcoholic fatty liver disease is the most common chronic liver disease and can present with advanced fibrosis or nonalcoholic steatohepatitis. The purpose of this study was to investigate the effect of a 7-day intense physical activity intervention on liver fat content in children with obesity. Fifty-seven obese children (mean body mass index: 26.5 ± 3.2 kg/m2; mean age: 12.0 ± 0.8 years) participated in a 7-day physical activity program. All participants were housed together, and their food intake and energy expenditure were strictly controlled. Anthropometric measurements, abdominal computerized tomography scans, and blood analyses were conducted at baseline and post-intervention. Participants lost weight by 2.53 ± 0.85 kg on average (61.0 ± 9.8 vs. 58.5 ± 9.5 kg, p < 0.05), fat mass (16.7 ± 5.1 vs. 15.7 ± 4.9 kg, p < 0.05), and serum insulin (13.7 ± 6.7 vs. 3.5 ± 2.0 μU/mL, p < 0.05). However, liver fat content was increased, presented as liver-to-spleen ratio (LSR) where lower LSR represents higher liver fat content. The intervention increased aspartate transaminase level (29.42 ± 6.78 IU/L vs. 33.50 ± 9.60 IU/L, p < 0.001). The change in liver fat content was not associated with the change in fasting insulin and liver enzymes. Short-term intense physical activity increased liver fat content independent of change in fasting insulin level and liver enzymes. This is the first human study to report increased liver fat content after physical activity-induced rapid weight loss.

Abstract Background: Pioglitazone is a promising therapeutic method for nonalcoholic fatty liver disease (NAFLD) patients with or without type 2 diabetes. However, there is remarkable variability in treatment response. We analyzed our previous randomized controlled trial to examine the effects of gender and other factors on the efficacy of pioglitazone in treating Chinese nonalcoholic fatty liver disease (NAFLD) patients with abnormal glucose metabolism.Methods: This is a post hoc analysis of a previous randomized, parallel controlled, open-label clinical trial (RCT)* with an original purpose of evaluating the efficacy of berberine and pioglitazone on NAFLD. The total population (n= 185) was randomly divided into three groups: lifestyle intervention (LSI), LSI + pioglitazone (PGZ) 15mg qd, and LSI + berberine (BBR) 0.5g tid, respectively, for 16 weeks. The study used proton magnetic resonance spectroscopy (1H- MRS) to assess liver fat content. Results: As compared with LSI, PGZ + LSI treatment induced further decreased liver fat content in women (-15.24% ± 14.54% vs. -8.76% ± 13.49%, p = 0.025), but less decreased liver fat content in men (-9.95% ± 15.18% vs. -12.64% ± 17.78%, p = 0.046). There was a significant interaction between gender and efficacy of pioglitazone before and after adjustment for age, smoking, drinking, baseline BMI, BMI change, treatment adherence, baseline liver fat content, and glucose metabolism.Conclusion: The study recommends pioglitazone plus lifestyle intervention for Chinese NAFLD female patients with abnormal glucose metabolism.* Trial registration: Role of Pioglitazone and Berberine in Treatment of Non-Alcoholic Fatty Liver Disease, NCT00633282.

Pioglitazone Treatment

Abstract Background : Pioglitazone is a promising therapeutic method for nonalcoholic steatohepatitis patients with or without type 2 diabetes. However, there is a remarkable variability in treatment response. We analyzed our previous randomized controlled trial to examine the effects of gender and other factors on the efficacy of pioglitazone treatment in liver fat content in Chinese nonalcoholic fatty liver disease (NAFLD) patients with abnormal glucose metabolism.Methods : This is a secondary post hoc analysis of a previous randomized, parallel controlled, open-label clinical trial (RCT)* with an original purpose of evaluating the efficacy of berberine and pioglitazone on NAFLD. The per protocol population (n= 184) was randomly divided into three groups: lifestyle intervention (LSI), LSI plus pioglitazone (PGZ) 15mg qd, and LSI plus BBR 0.5g tid, respectively, for 16 weeks. Proton magnetic resonance spectroscopy ( 1 H MRS) was used to assess liver fat content.Results : As compared with LSI, PGZ plus LSI treatment induced further decreased liver fat content in women [-8.26% (-17.18%, -0.65%), p = 0.025], but relatively increased liver fat content in men [9.79% (0.37%, 19.21%), p = 0.046]. There was a significant interaction between gender and efficacy of pioglitazone before ( p = 0.003) and after ( p = 0.011) adjustment for age, smoking, drinking, baseline BMI, BMI change, and treatment adherence.Conclusion : For Chinese NAFLD patients with abnormal glucose metabolism, pioglitazone treatment is recommended for women, but not for men, based on lifestyle interventions.* Trial registration: Role of Pioglitazone and Berberine in Treatment of Non-Alcoholic Fatty Liver Disease, NCT00633282.
