Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common noncommunicable diseases worldwide. The present study aimed to investigate the effects of oleoylethanolamide (OEA) supplementation combined with calorie restriction on inflammation, body composition, and hepatic fibrosis among obese patients with NAFLD. In this 12-week randomized clinical trial, 76 obese patients newly diagnosed with NAFLD were randomly allocated into either OEA or placebo group. The weight-loss diet was also designed for both groups. Pre- and postintervention messenger RNA expression levels of the transcription factor nuclear factor-κB (NF-κB), interleukin-6 (IL-6) and IL-10, body composition, and NAFLD fibrosis score were assessed. At the end of the study, the OEA group showed lower NF-κB and IL-6 expression levels compared to the placebo (p < .01). However, IL-10 expression level was approximately twofold higher in the OEA group compared to the placebo group (p = .008). A significant reduction was observed in the fat mass of the OEA group compared to the placebo (p = .044) postintervention. In addition, OEA supplementation led to a significant increase in fat-free mass in the OEA group compared to the placebo (p = .032). A remarkable increase was observed in resting metabolic rate (RMR) in the OEA group (p = .009); however, it was not found in the placebo group. There were no significant between-group differences in RMR postintervention. In addition, no significant within-and between-group differences were observed in the NAFLD fibrosis score at the end of the trial. Treatment with OEA along with weight-loss intervention could significantly improve inflammation and body composition in patients with NAFLD.

Abstract
INTRODUCTION The effect of branched-chain amino acid (BCAA) supplementation on muscle mass in patients with cirrhosis and sarcopenia is unknown. METHODS This is a pilot, prospective, randomized, and double-blind study of a cohort of 32 patients with cirrhosis and sarcopenia diagnosed by computed tomography scan who underwent a nutritional and physical activity intervention for 12 weeks. They were divided into 2 groups (placebo: 17 patients; BCAA 15 patients). The study protocol was registered at ClinicalTrials.gov (NCT04073693). RESULTS Baseline characteristics were similar in both groups. After treatment, only the BCAA group presented a significant improvement in muscle mass (43.7 vs 46 cm2/m2; P = 0.023). Seventeen patients (63%) presented improvement in muscle mass overall, which was more frequent in the BCAA group (83.3 vs 46.7%; P = 0.056). Regarding frailty, there was a significant improvement in the Liver Frailty Index in the global cohort (n = 32) after the 12 weeks (4.2 vs 3.9; P < 0.001). This difference was significant in both groups: in the placebo group (4.2 vs 3.8; P < 0.001) and in the BCAA group (4.2 vs 3.9; P < 0.001). After treatment, the BCAA group had a higher increase in zinc levels than the placebo group (Δzinc: 12.3 vs 5.5; P = 0.026). In addition, there was a trend for greater improvement of albumin levels in the BCAA group (Δalbumin: 0.19 vs 0.04; P = 0.091). DISCUSSION BCAA supplementation improves muscle mass in cirrhotic patients with sarcopenia.

Abstract
BACKGROUND Sarcopenia worsens patient prognoses in chronic liver disease. This study aimed to elucidate the effects of vitamin D supplementation on skeletal muscle volume and strength in patients with decompensated cirrhosis. METHODS Thirty-three patients were entered into the study based on the criteria and then randomly assigned to two groups: Group A (n = 17), the control group, and Group B (n = 16), those who received oral native vitamin D3 at a dose of 2000 IU once a day for 12 months. RESULTS SMI values in Group B were significantly increased at 12 months (7.64 × 10-3). The extent of changes in the SMI and grip strength in Group B were significantly greater than that in Group A at 12 months (p = 2.57 × 10-3 and 9.07 × 10-3). The median change rates in the SMI were +5.8% and the prevalence of sarcopenia was significantly decreased from 80.0% (12/15) to 33.3% (5/15; p = 2.53 × 10-2) in Group B. CONCLUSIONS Vitamin D supplementation might be an effective and safe treatment option for patients with decompensated cirrhosis to increase or restore the skeletal muscle volume and strength or prevent the muscle volume and strength losses.

Abstract
INTRODUCTION This study explored the relationship between patatin-like phospholipase domain-containing 3 gene (PNPLA3 rs738409), nutrient intake, and liver histology severity in patients with nonalcoholic fatty liver disease (NAFLD). METHODS PNPLA3-rs738409 variant was genotyped in 452 non-Hispanic whites with histologically confirmed NAFLD who completed Food Frequency Questionnaire within 6 months of their liver biopsy. The fibrosis severity on liver histology was the outcome of interest. RESULTS The distribution of PNPLA3 genotypes was CC: 28%, CG: 46%, and GG: 25%. High-carbohydrate (% of energy/d) intake was positively associated (adjusted [Adj] odds ratio [OR]: 1.03, P < 0.01), whereas higher n-3 polyunsaturated fatty acids (n-3 PUFAs) (g/d) (Adj. OR: 0.17, P < 0.01), isoflavones (mg/d) (Adj. OR: 0.74, P = 0.049), methionine (mg/d) (Adj. OR: 0.32, P < 0.01), and choline (mg/d) (Adj. OR: 0.32, P < 0.01) intakes were inversely associated with increased risk of significant fibrosis (stage of fibrosis ≥2). By using an additive model of inheritance, our moderation analysis showed that PNPLA3 rs738409 significantly modulates the relationship between carbohydrate (%), n-3 PUFAs, total isoflavones, methionine, and choline intakes and fibrosis severity in a dose-dependent, genotype manner. These dietary factors tended to have a larger and significant effect on fibrosis severity among rs738409 G-allele carriers. Associations between significant fibrosis and carbohydrates (Adj. OR: 1.04, P = 0.019), n-3 PUFAs (Adj. OR: 0.16, P < 0.01), isoflavones (Adj. OR: 0.65, P = 0.025), methionine (Adj. OR: 0.30, P < 0.01), and total choline (Adj. OR: 0.29, P < 0.01) intakes remained significant only among rs738409 G-allele carriers. DISCUSSION This gene-diet interaction study suggests that PNPLA3 rs738409 G-allele might modulate the effect of specific dietary nutrients on risk of fibrosis in patients with NAFLD.

Abstract
OBJECTIVES Current study aimed to find the effects of curcumin on quality of life (QoL) in liver cirrhotic patients. DESIGN In this randomized double-masked placebo-controlled trial, 70 cases with liver cirrhosis aged 20-70 years were randomly divided into two groups to receive 1000 mg/day curcumin (n = 35) or placebo (n = 35) for 12 weeks. The health-related QoL (HRQoL) was assessed by CLDQ, LDSI 2.0, and SF-36. RESULTS Fifty-eight patients (28 in curcumin and 30 in placebo groups) finished the research. Compared with baseline, overall scores as well as most of CLDQ domains (e.g. Fatigue, Emotional Function, Worry, Abdominal Symptoms, and Systemic Symptoms) and the Physical and Mental health (Total) scores and most of SF-36 domains (e.g. Physical Functioning, Bodily Pain, Vitality, Social Functioning, and Mental Health) increased considerably (P < 0.05) after curcumin administration. Furthermore, curcumin reduced most of LDSI 2.0 domains (e.g. Itch, Joint pain, Pain in the right upper abdomen, Sleeping during the day, Decreased appetite, Depression, Fear of complication, Jaundice, Hindrance in Financial Affairs, Change in use of time, Decreased sexual interest, and Decreased sexual activity) significantly (P < 0.05). Significant differences were noticed between two groups in CLDQ domains and overall scores, LDSI 2.0 domains and overall scores, SF-36 Physical and Mental health (total) scores and all its domains scores (P < 0.05), adjusting for baseline values and disease duration. CONCLUSIONS Curcumin improved QoL in liver cirrhotic patients according to CLDQ, LDSI 2.0, and SF-36 domains. Additional studies are warranted to consider curcumin as a safe, accessible, and low-cost complementary therapeutic option in cirrhosis.

European journal of gastroenterology & hepatology. 2020;(4):535-539
Abstract
INTRODUCTION The present study was conducted to compare the efficacy and side effects of Spironolactone and Eplerenone in management of ascites due to liver cirrhosis. MATERIALS AND METHODS 105 patients of ascites with liver cirrhosis were randomized into three groups of 35 patients each. Group I was given Spironolactone 100 mg, group II was given Eplerenone 100 mg and group III was given Eplerenone 50 mg. All patients were put on salt-restricted diet (less than or equal to 2 g of sodium) and no loop diuretics were used. Patients were followed after 7 days from the baseline and then biweekly for the period of three months and serial measurements of weight, abdominal girth and incidence of side effects especially gynecomastia, mastalgia, hyperkalemia were recorded. Results were compared. Patients having Child-Turcotte-Pugh score-C, massive ascites, hepatic encephalopathy, Hepatorenal syndrome and ascites due to cardiac, renal, malignant causes were excluded. OBSERVATIONS Difference in mean weight reduction was non significant (P = 0.964) in group I and group II whereas the difference was significant when comparison was made between Group I and III; and Group II and III (P = <0.001, <0.001, respectively). In group I, the incidence of gynecomastia was 14.28% whereas in group II and group III no case of gynecomastia was observed (P <0.001, <0.001). Hyperkalemia was present in one patient (2.8%) in group I whereas no patient developed hyperkalemia in group II and group III (P = >0.05, >0.05). CONCLUSION Eplerenone and spironolactone are equally effective in management of ascites due to liver cirrhosis but side effect profile of eplerenone scores over Spironolactone.

Yao, J, Zhou, X, Kong, M, Li, L, Hua, X, Zhao, Y, Yu, S, Chen, Y, Duan, Z
Asia Pacific journal of clinical nutrition. 2018;(2):322-328
Abstract
BACKGROUND AND OBJECTIVES Respiratory quotient (RQ) is a good marker of substrate oxidation. Low RQ is fre-quently found in patients with liver cirrhosis and is associated with poor outcome. The purpose of this study was to demonstrate the effects of eating frequency on RQ in patients with cirrhosis. METHODS AND STUDY DESIGN We performed a randomized controlled trial to assess the effects of eating frequency on RQ in patients with cirrhosis. Seventy patients and 30 healthy controls were enrolled, and patients were further randomized to receive either normal eating frequency (NEF) meals at 08:00, 12:00 and 18:00 h, or high eating frequency (HEF) meals at 08:00, 10:00, 12:00, 15:00, 18:00 and 20:00 h. The two groups had equivalent energy intake. Fasting RQ was measured at 07:30 h and daytime RQ was measured at 11:30 and 17:30 h. Disease severity was evaluated using the Child-Turcotte-Pugh (CTP) classification. RESULTS Fasting RQ and daytime RQ were significantly lower in patients with cirrhosis than in healthy controls. Patients in the HEF group had a higher RQ than patients in the NEF group at three time points. In patients with CTP-A, no significant differences in daytime RQ were observed between the two groups. However, in CTP-C patients, daytime RQ was significantly higher in the HEF group than in the NEF group. Serum free fatty acid levels were significantly decreased and albumin was significantly increased after HEF intervention. CONCLUSIONS HEF strategy is effective in improvement of RQ and is beneficial to patients with cirrhosis.

Abstract
BACKGROUND AND AIMS Patients with refractory ascites (RA) require repeated large volume paracenteses (LVP), which involves frequent hospital visits and is associated with a poor quality-of-life. This study assessed safety and efficacy of an automated, low-flow pump (alfapump® [AP]) compared with LVP standard of care [SoC]. METHODS A randomized controlled trial, in seven centers, with six month patient observation was conducted. Primary outcome was time to first LVP. Secondary outcomes included paracentesis requirement, safety, health-related quality-of-life (HRQoL), and survival. Nutrition, hemodynamics, and renal injury biomarkers were assessed in a sub-study at three months. RESULTS Sixty patients were randomized and 58 were analyzed (27 AP, 31 SoC, mean age 61.9years, mean MELD 11.7). Eighteen patients were included in the sub-study. Compared with SoC, median time to first LVP was not reached after six months in the AP group, meaning a significant reduction in LVP requirement for the AP patients (AP, median not reached; SoC, 15.0days (HR 0.13; 95%CI 13.0-22.0; p<0.001), and AP patients also showed significantly improved Chronic Liver Disease Questionnaire (CLDQ) scores compared with SoC patients (p<0.05 between treatment arms). Improvements in nutritional parameters were observed for hand-grip strength (p=0.044) and body mass index (p<0.001) in the sub-study. Compared with SoC, more AP patients reported adverse events (AEs; 96.3% vs. 77.4%, p=0.057) and serious AEs (85.2 vs. 45.2%, p=0.002). AEs consisted predominantly of acute kidney injury in the immediate post-operative period, and re-intervention for pump related issues, and were treatable in most cases. Survival was similar in AP and SoC. CONCLUSIONS The AP system is effective for reducing the need for paracentesis and improving quality of life in cirrhotic patients with RA. Although the frequency of SAEs (and by inference hospitalizations) was significantly higher in the AP group, they were generally limited and did not impact survival. Lay summary: The alfapump® moves abdominal fluid into the bladder from where it is then removed by urination. Compared with standard treatment, the alfapump reduces the need for large volume paracentesis (manual fluid removal by needle) in patients with medically untreatable ascites. This can improve life quality for these patients. www.clinicaltrials.gov#NCT01528410.

European journal of gastroenterology & hepatology. 2017;(11):1247-1250
Abstract
BACKGROUND Hepatorenal syndrome (HRS) is a severe complication of liver cirrhosis, with poor survival. Rifaximin is a gut-selective broad-spectrum antibiotic. AIM: The aim of this study was to evaluate the role of rifaximin as a primary prevention of HRS. PATIENTS AND METHODS Eighty patients with liver cirrhosis and ascites were enrolled. They were randomized into two groups: control (n=40) and rifaximin group (n=40). Baseline liver function tests, renal function tests, complete blood count, international normalized ratio, urine analysis, and abdominal ultrasonography were carried out. Rifaximin 550 mg was administered twice daily for 12 weeks. Renal functions were measured every 4 weeks with monitoring of HRS occurrence and possible precipitating factor. RESULTS Both groups were matched for age, sex, virology, serum bilirubin, serum albumin, aspartate aminotransferase, alanine aminotransferase, hemoglobin, white blood cells, platelets, international normalized ratio, potassium, and Child-Pugh score. In contrast to the rifaximin group, the control group showed statistically significant serial blood urea nitrogen (18.84±7.17, 19.85±6.10, 21.54±4.79, and 22.96±5.82 mg/dl; P=0.001) and serum creatinine (0.94±0.25, 1.02±0.24, 1.12±0.16, and 1.21±0.17 mg/dl; P=0.001) levels. The overall blood urea nitrogen and serum creatinine change was statistically higher in the control group than the rifaximin group (20.8 vs. 18.24 mg/dl and 1.07 vs. 0.99 mg/dl, respectively). HRS developed more in the control group than the rifaximin group [9 (22.5%) vs. 2 (5%); P=0.048]. In both groups, HRS was precipitated by spontaneous bacterial peritonitis mainly and large volume paracentesis. The Child-Pugh score, control group, baseline serum sodium, and creatinine were predictors of HRS. CONCLUSION Rifaximin may be useful as a primary prevention of HRS.
