“…However, the strong impact of an elevated AST/ALT ratio on BARD score has to be considered, which is not specific for hepatic damage. In a recently published study, the BARD score displayed a lack of specificity for hepatic fibrosis compared to FIB-4, which is in line with our present results [ 30 ]. Furthermore, BARD is primarily applicable in order to predict manifested and advanced fibrosis in NAFLD, whereas NFS represents a reliable tool for the exclusion of individuals with a low risk of fibrosis [ 31 ].…”

Obesity and type 2 diabetes mellitus (T2D) represent important comorbidities of the metabolic syndrome, which are associated with non-alcoholic fatty liver disease (NAFLD)-related hepatic fibrosis. In total, 160 morbidly obese patients—81 following a low-calorie formula diet (LCD) program and 79 undergoing bariatric surgery (Roux-en-Y gastric bypass, RYGB)—were examined for anthropometric and metabolic parameters at base-line and during 12 months of weight loss, focusing on a putative co-regulation of T2D parameters and liver fibrosis risk. High NAFLD fibrosis scores (NFS) before intervention were associated with elevated HbA1c levels and T2D. Loss of weight and body fat percentage (BFL) were associated with improved glucose and lipid metabolism and reduced risk of NAFLD-related fibrosis, with particularly beneficial effects by RYGB. Both T2D improvement and NFS decrease were positively associated with high BFL. A highly significant correlation of NFS reduction with BFL was restricted to male patients while being absent in females, accompanied by generally higher BFL in men. Overall, the data display the relation of BFL, T2D improvement, and reduced NAFLD-related fibrosis risk during weight loss in morbidly obese individuals induced by diet or RYGB. Furthermore, our data suggest a considerable sexual dimorphism concerning the correlation of fat loss and improved risk of liver fibrosis.

“…Most studies found that Forns and S-index had a greater diagnostic accuracy than other models, even if the AUROC values of models in various studies were substantially diverse. 35 , 36 Currently, however, the study sample size is too small, and the majority of studies are focused on NAFLD or HCV instead. In this study, we looked at a large group of HBV-positive individuals, a total of 436.…”

Background At present, there is a lack of cheap, effective and convenient detection methods for hepatitis B-related liver fibrosis, especially in the developing area. Aim To evaluate the non-invasive methods for the significant and advanced fibrosis stage in chronic hepatitis B virus (HBV) patients in basic hospitals and to assess their diagnostic utility. Methods The study included 436 consecutive naive HBV individuals who had their livers biopsied. They were examined in one week using aspartate aminotransferase-to-aspartate aminotransferase ratio (AAR), age-platelet index (API), aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 (FIB-4), Forns, gamma-glutamyl transpeptidase-to-platelet ratio (GPR), S-index and transient elastography (TE). Scheuer scoring system was used to determine the histologic fibrosis grades (S0–S4). The diagnostic effectiveness was assessed using AUROCs and the DeLong test, both of which were based on statistical comparisons. Results For both substantial (≧S2) and advanced (≧S3) fibrosis phases, TE had good diagnostic performance in determining the hepatic fibrosis. Similar diagnostic performance was shown with Forns and S-index when it came to detecting fibrosis stages lower than S3. One model’s diagnostic value was not significantly improved by combining serum models. Correlation coefficients between clinical features and fibrosis phases were greatest for Forns ( r = 0.397), S-index ( r = 0.382) and TE ( r = 0.535) when compared to other variables. Conclusion This investigation showed that Forns and S-index may be helpful strategies for detecting advanced fibrosis in HBV patients admitted to community hospitals.

“…There are changes in the collagen profile of liver tissue with increased related amounts of collagen types I and III associated with modification and cross-linking process of ECM components due to persisting inflammation [5,6].There are certain methods to induce hepatic fibrosis by common bile duct ligation [7] is the common and safer methods which leads to an acute obstructive jaundice within two weeks and progressive fibrosis is anticipated in approximately 4 or 6 weeks later where four weeks duration is thought to be enough to cause a moderate cell necrosis and fatty infiltration [8,9]. The actual methods for assessment of hepatic fibrosis consist of noninvasive methods based on conventional imaging methods include ultrasonography [10], computed tomography (CT) [11], and magnetic resonance imaging (MRI) [12], Newer acoustic approaches, like as transient elastography, can improve the accuracy of ultrasonography, CT, and MRI in diagnosing fibrosis or early cirrhosis [13], Acoustic radiation force impulse imaging [14], Two-dimensional shear wave elastography, Magnetic resonance elastography [15]. Ultrasonography is a more practical choice for initial diagnostic and follow-up exams since it is a safe, non-invasive, and affordable procedure that does not require sedation or anesthesia [16,17].…”

HE current study used ultrasound to assess the induced hepatic fibrosis by ligation of common bile duct using surgical stainless-steel wire in 18 healthy local adult dogs of both sexes, weighing (20±5) kgs and aged (24±6) months. All animals were subjected to evaluated the progression of hepatic fibrosis by clinical and ultrasound examinations using a transabdominal convex transducer at frequency (5 MHz) to diagnose developing of surgically induced hepatic fibrosis at 0, 7, 14 and 21 days, respectively, after ligation of the common bile duct. Clinical results such as severe abdominal pain, anorexia, emaciation, jaundice and pale of mucus membrane were observed. Ultrasonographical examination of liver revealed dilatation of the gallbladder, common bile duct and portal vein as well as increased in thickness and echogenicity of liver tissue starting from the 7 th day post-ligation till reaching the maximum in the 21 days. There was a significant difference in echogenicity of liver parenchyma between groups during the 0,7,14 and 21 days of the experiment in all dogs p<0.01. In conclusion, the use of ultrasound imaging to diagnose, evaluate and follow-up the diffused liver disease models is feasible and beneficial value to monitor the development of levels and stages of hepatic fibrosis and cirrhosis of individual dogs.
