Patients with genotypes A/A, A/G and G/G of an SNP of OAS-1 at the exon 3 of its coding sequence were at gradient increased risks of suffering from higher serum alanine aminotransferase (P<0.001) and aspartate aminotransferase (P=0.001), higher degree of liver fibrosis (P=0.010) and higher presence of liver cirrhosis (P=0.001).
Multivariate analysis did identify (i) four independent variables that could explain the degree of liver fibrosis-the sex of the patient, the number of blood units received before transplantation, increased ALT levels at the time of LB, and the occurrence of at least one acute rejection episode (thus the receipt of methylprednisolone pulses); and (ii) two independent variables associated with the occurrence of CAH-the number of blood units before transplantation and increased ALT levels at the time of LB.
Liver biopsy may be recommendable in patients coinfected with HIV and HCV who have persistently normal ALT levels, to determine the extent of liver fibrosis and, consequently, to assess suitability for treatment.
Linear regression analysis revealed that alanine aminotransferase (odds ratio [OR]: 0.03, 95% confidence intervals [CI]: 0.02-0.05, P < 0.001), AST (OR: -0.1, 95% CI: -0.02 to -0.01, P < 0.001), and liver fibrosis (OR: 0.30, 95% CI: 0.01-0.59, P = 0.043) were the independent factors correlated to serum WFA<sup>+</sup>-M2BP level.
It is suggested that this noninvasive score system can accurately predict hepatic fibrosis and may reduce the need for liver biopsy in HBeAg-positive patients with normal or minimally elevated ALT levels.
Interferon-λ3 levels were significantly higher after viral clearance in patients who developed HCC and were associated with a higher potential for hepatocarcinogenesis, such as a higher frequency of non-hypervascular hypointensive nodules (P = 0.046), higher stages of liver fibrosis (P < 0.001), and higher post-treatment levels of Wisteria floribunda agglutinin positive Mac-2 binding protein (P < 0.001) and alanine aminotransferase (P < 0.001).
Infusion of human macrophages in a murine liver fibrosis model demonstrated a decrease in markers of liver injury (alanine transaminase, bilirubin, aspartate transaminase) and fibrosis (transforming growth factor-β, α-smooth muscle actin, phosphatidylserine receptor) and an increase in markers of liver regeneration (matrix metalloproteinases [MMP]-9, MMP-12 and TNF-related weak inducer of apoptosis).
In vivo, overexpression of Sestrin 2 reduced the ALT and AST levels as well as the α-SMA and Col1A1 protein expression in the CCl4 model of liver fibrosis.
In the 12-week arm, significant improvements were observed in biomarkers of liver injury (alanine aminotransferase: -53.7 U/L, P < 0.001; aspartate aminotransferase: -35.9 U/L, P < 0.001) and liver fibrosis (aspartate aminotransferase to platelet ratio index: -0.987, P < 0.001; fibrosis-4 index: -1.165, P < 0.001).
In contrast, the IL28B genotype did not affect the biochemical markers, such as alanine aminotransferase, hepatic fibrosis markers, and α-fetoprotein, and the degree of hepatic fibrosis assessed by transient elastography in HCV carriers.
In AIH group, serum galectin-9 levels weakly correlated with alanine aminotransferase levels or total bilirubin (TB) and strongly correlated with C-X-C motif chemokine 10 (CXCL10) and Mac-2 binding protein glycosylation isomer (M2BPGi) levels, but did not correlate with the histological grade of liver fibrosis.
In addition, dapagliflozin decreased serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), hepatic lipid accumulation as determined by H&E and Oil Red O staining, and Coherent Anti-Stokes Raman Scattering (CARS) microscopy, and hepatic fibrosis as determined by picrosirius red (PSR) staining and TPE-SHG microscopy in WD-fed mice.
In addition, concomitant significant liver fibrosis was identified in 60 (5.1%) subjects with NAFLD, and its independent predictors were age [odds ratio (OR) 1.054], ALT level (OR 1.019), BMI (OR 1.217), and diabetes (OR 1.987) (all P < 0.05).
Improvement of liver fibrosis was found in 12% to 30% of patients in each ALT subgroup and in 24% of all patients in group A and there were no significant differences in liver fibrosis in comparison with findings in of group B when assessed by staging alone.
Importantly, most of these miRNAs significantly and positively correlated with ALT and aspartate aminotransferase (AST) levels, and liver fibrosis stage (p < 0.05).
Impact of Obesity and Alanine Aminotransferase Levels on the Diagnostic Accuracy for Advanced Liver Fibrosis of Noninvasive Tools in Patients With Nonalcoholic Fatty Liver Disease.
HCV genotype 3, older age, and elevated alanine aminotransferase levels are independent predictors of advanced liver fibrosis in HCV-HIV-coinfected patients.
Genistein co-treatment significantly attenuated D-GalN-induced chronic liver damage and liver fibrosis as evident from a significant amelioration in functional impairment, including inhibition of the activation of Hepatic stellate cells (HSC), decreased expression in alpha smooth muscle actin (α-SMA) and accumulation of collagen matrix, and an elevation in serum alanine transaminase (ALT) and aspartate transaminase (AST) level.
