Aim. To review available data on the role of the microbiome and intestinal mucosal barrier in the development and progression of non-alcoholic fatty liver disease (NAFLD).Key points. The role of the human microbiome in the development and progression of NAFLD is associated with its effects on the risk factors (obesity, insulin resistance, type 2 diabetes), permeability of the intestinal barrier and absorption of such substances as short-chain fatty acids, bile acids, choline and endogenous ethanol. Liver fibrosis constitutes the leading factor determining the prognosis of patients in NAFLD, including cases associated with cardiovascular complications. Changes in the microbiome composition were demonstrated for various degrees of fibrosis in NAFLD.Conclusion. The results of modern studies confirm the formation of a new concept in the pathophysiology of NAFLD, which encourages the development of new therapeutic strategies.

Background: Nowadays, generating shear waves and simulation of the liver tissue is done using point shear-wave elastographic (pSWE) techniques which uess acoustic radiation force impulse (ARFI). Objective: This study aimed to evaluate the correlation between pSWE and liver function tests (LFTs) to predict liver fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). Materials and methods: It was a cross sectional study conducted in an Ultrasound Clinic in Suleymaniya city. The duration of the study was from 1st of November, 2018 to 30th of June, 2019 which conducted on 50 NAFLD patients. After confirming NAFLD diagnosis, the patients were referred to Ultrasound Clinic to go under pSWE test. Results: The data showed that the mean PSWE of NAFLD patient was 4.12±0.87 Kpa; and 18% of them had high PSWE (> 4.6). Elastography fibrosis score was distributed to F0 (82%), F1 (6%), F2 (8%) and F3 (4%). There was a significant association between high APRI and high Aspartate Aminotransferase/Alanine Aminotransferase(AST/ALT) ratio (p=0.04). There was also a highly significant association between elastography fibrosis score and APRI fibrosis score among NAFLD patients (p<0.001). Conclusion: This study showed that the pSWE is a valuable noninvasive diagnostic technique for predicting liver fibrosis among NAFLD patients and there is significant correlation between APRI and pSWE scores.

Non-alcoholic fatty liver disease (NAFLD) is a chronic disease affecting up to 25% of the population worldwide. n-3 long-chain polyunsaturated fatty acids (n-3 PUFA) have been associated with improved clinical parameters of NAFLD. Our purpose was to conduct a pilot study to evaluate the effects of n-3 PUFA supplementation in a randomized, double-blind, placebo-controlled clinical study performed on NAFLD individuals diagnosed by ultrasound. Patients received n-3 PUFA (n = 13) or placebo (n = 11) supplementation for six months. Circulating miR-122 expression (determined by quantitative real time-polymerase chain reaction (qRT-PCR), liver fibrosis (FibroScan®), red blood cells (RBC) fatty acids (gas chromatography), and biochemical tests were performed at baseline and after intervention. After the intervention, in the n-3 PUFA group, docosahexaenoic acid (DHA) and omega index increased significantly in RBC (p = 0.022 and p = 0.012, respectively), in addition to a significant reduction in alkaline phosphatase (ALP) (p = 0.002) and liver fibrosis (p = 0.039). However, there was no change in the expression of circulating miR-122 in both groups. Our results showed that omega-3 PUFA were incorporated in erythrocytes after six months of fish oil supplementary intake, and that n-3 PUFA were effective in reducing ALP and liver fibrosis without altering the expression of circulating miR-122 in individuals with NAFLD.

Non-alcoholic fatty liver disease (NAFLD) is gaining in importance and is linked to obesity. Especially, the development of fibrosis and portal hypertension in NAFLD patients requires treatment. Transgenic TGR(mREN2)27 rats overexpressing mouse renin spontaneously develop NAFLD with portal hypertension but without obesity. This study investigated the additional role of obesity in this model on the development of portal hypertension and fibrosis. Obesity was induced in twelve-week old TGR(mREN2)27 rats after receiving Western diet (WD) for two or four weeks. Liver fibrosis was assessed using standard techniques. Hepatic expression of transforming growth factor-β1 (TGF-β1), collagen type Iα1, α-smooth muscle actin, and the macrophage markers Emr1, as well as the chemoattractant Ccl2, interleukin-1β (IL1β) and tumor necrosis factor-α (TNFα) were analyzed. Assessment of portal and systemic hemodynamics was performed using the colored microsphere technique. As expected, WD induced obesity and liver fibrosis as confirmed by Sirius Red and Oil Red O staining. The expression of the monocyte-macrophage markers, Emr1, Ccl2, IL1β and TNFα were increased during feeding of WD, indicating infiltration of macrophages into the liver, even though this increase was statistically not significant for the EGF module-containing mucin-like receptor (Emr1) mRNA expression levels. Of note, portal pressure increased with the duration of WD compared to animals that received a normal chow. Besides obesity, WD feeding increased systemic vascular resistance reflecting systemic endothelial and splanchnic vascular dysfunction. We conclude that transgenic TGR(mREN2)27 rats are a suitable model to investigate NAFLD development with liver fibrosis and portal hypertension. Tendency towards elevated expression of Emr1 is associated with macrophage activity point to a significant role of macrophages in NAFLD pathogenesis, probably due to a shift of the renin–angiotensin system towards a higher activation of the classical pathway. The hepatic injury induced by WD in TGR(mREN2)27 rats is suitable to evaluate different stages of fibrosis and portal hypertension in NAFLD with obesity.
