METHODS: We have included 493 patients with sonographic evidence of a fatty change, and 177 of these individuals were evaluated and confirmed after liver biopsy. The exclusion criteria consisted of significant alcohol abuse (【 20 g daily), evidence of hepatitis B and C, evidence of drug-induced fatty liver disease and other specific liver diseases such as hemochromatosis, Wilson’s disease or autoimmune liver disease. The patients were assessed for metabolic syndrome, and biochemical, anthropometric and histopathological evaluations were carried out. The degree of disease activity in the NAFLD patients was evaluated using the NAFLD Activity Score. The data were analyzed by SPSS, version 16.0. RESULTS: Females predominated among the study participants (250, 57.0%), and the mean age was 40.8 ± 10.2 years. The numbers of overweight, obeseⅠ and obese Ⅱ patients were 58 (13.2%), 237 (53.9%) and 93 (21.2%), respectively. However, there were 422 (96.2%) centrally obese patients. NASH was absent in 10 (5.6%) cases, borderline in 92 (52.6%) cases and present in 75 (42.4%) cases. The presence of diabetes could significantly (P = 0.001) differentiate NASH from simple steatosis. The following parameters did not influence the development of NASH: age, sex, basal metabolic index, waist circumference, serum high-density lipoprotein, triglyceride, insulin resistance index, hypertension and metabolic syndrome. The serum gammaglutamyl transpeptidase (GGT) level was significantly higher (P = 0.05, 51.7 ± 32.8 and 40.4 ± 22.6 U/L) in the NASH patients, with a sensitivity of 45% and a specificity of only 68%. The serum alanine aminotransferase and aspartate aminotransferase levels were not able to predict NASH. CONCLUSION: Females were the predominant sufferers of NAFLD in Bangladesh. The prevalence of NASH was high. Diabetes was found to be the main culprit in developing NASH. GGT was the only biochemical marker of NASH. We recommend liver biopsy in NAFLD patients who have diabetes and elevated GGT.展开更多

METHODS: In 72 patients affected by NAFLD, main metabolic, hepatic and anti-inflammatory parameters were assayed after 3 mo of a restricted diet and before silymarin treatment (twice a day orally). The brightness of liver echography texture (hepatorenal ratio brightness) was also defined at same time. These evaluations were repeated after 6 mo of treatment. RESULTS: Serum levels of some metabolic and anti-inflammatory data nonsignificantly lowered after 6 mo of silymarin. On the contrary, Steato test, alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transpeptidase were significantly (P < 0.001) reduced. Instead, the AST/ALT ratio unchanged. Finally, the hepatorenal brightness ratio, as an index of hepatic steatosis, significantly (P < 0.05) dropped. CONCLUSION: The obtained results indicate that silymarin appears to be effective to reduce the biochemical, inflammatory and ultrasonic indices of hepatic steatosis. Some parameters indicative of early stage of atherosclerosis were also lowered.展开更多

This study was designed to detect the changes of hepatic enzymes after alcohol intake and evaluate the corresponding damage to the human body. METHODS: Fifteen volunteers were included according to the criteria. After the intake of 80g ethanol containing beverage, alcohol levels were detected and blood samples were collected at 0.5-to 3-hour interval to detect the levels of hepatic enzymes simultaneously. RESULTS: After the intake of 80g ethanol, various symptoms occurred in volunteers while the concentration of blood alcohol peaked at 1 hour and normalized within 24 hours. The ratio of alanine aminotransferase (ALT) to aspartate aminotransferase (AST) increased significantly when the venous alcoholic concentration increased from 0g/L to 1.2g/L and the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase(γ-GT) were elevated when the alcoholic concentration reached 0.4g/L. No significant changes were noticed in ALT, AST or cholinesterase (CHE). CONCLUSION: Acute alcohol intoxication may cause the changes of hepatic enzymes and prove the existence of reversible hepatic injury.展开更多

After the intake of 80g ethanol containing beverage, alcohol levels were detected and blood samples were collected at 0.5-to 3-hour interval to detect the levels of hepatic enzymes simultaneously. RESULTS: After the intake of 80g ethanol, various symptoms occurred in volunteers while the concentration of blood alcohol peaked at 1 hour and normalized within 24 hours. The ratio of alanine aminotransferase (ALT) to aspartate aminotransferase (AST) increased significantly when the venous alcoholic concentration increased from 0g/L to 1.2g/L and the levels of alkaline phosphatase (ALP) and gamma-glutamyl transpeptidase(γ-GT) were elevated when the alcoholic concentration reached 0.4g/L. No significant changes were noticed in ALT, AST or cholinesterase (CHE). CONCLUSION: Acute alcohol intoxication may cause the changes of hepatic enzymes and prove the existence of reversible hepatic injury.
