We evaluated the relationship between genetic polymorphisms of the renin-angiotensin system (A1166C angiotensin II type 1 receptor (AT1R), angiotensinogenT174M and M235T, and angiotensin-converting enzyme I/D) and the effects of losartan on portal and systemic hemodynamic in patients with cirrhosis and portal hypertension.
In this respect, we investigated the impact of functional genetic polymorphisms of TGF-beta1 (codon 10 Leu/Pro, codon 25 Arg/Pro), TNF-alpha (-308 G/A, -238 G/A) and angiotensinogen (-6 G/A) on the development of cirrhosis in HHC.
Polymorphisms of the core promoter region of the AGT gene (AGT-20 and AGT-6) were associated with liver cirrhosis in patients with chronic hepatitis B.
Polymorphisms of the core promoter region of the AGT gene (AGT-20 and AGT-6) were associated with liver cirrhosis in patients with chronic hepatitis B.
During follow-up, two patients of the control group and three patients of the IFN group developed cirrhosis, and one of the IFN- treated patients progressed to hepatocellular carcinoma.
The following thrombotic factors were evaluated in 68 hepatitis C patients with prothrombin activity >/= 80% (34 consecutive patients with extensive fibrosis and/or cirrhosis compared with 34 consecutive patients without extensive fibrosis and/or cirrhosis): factor V Leiden, G20210A prothrombin mutation, antithrombin, protein C and S deficiencies, hyperhomocysteinemia, elevated factor VIII level, and lupus anticoagulant.
Plasma concentrations of factor II, VII, X, V, protein C (PC) total protein S (tPS) antithrombin (AT) and D-dimers (DD) were measured in 13 LC patients with PVT heterozygous for PT G20210A, in 13 LC patients with PVT without PTG20210A and in 13 LC controls matched by age, sex and Child-Pugh score.
The presence of the relatively high frequency of A1AT S and HFE H63D allele carriers in Egyptian cases of HCV liver cirrhosis suggest the necessity to implement routine molecular analysis of these genes for detection of risk genotypes among affected families.
The altered proteins are related to the development of liver pathology, such as cirrhosis (α1-antiproteinase), thrombosis (fibrinogen, plasminogen), and inflammation (mannose-binding protein A, complement C4, complement factor B), contributing to liver steatosis or hepatic cell death.
After adjusting for cirrhosis, platelet count, alanine aminotransferase and sex, the following factors were independently associated with one-year mortality: Charlson index (hazard ratio [HR] 1.55; 95% CI 1.29-1.86; p = 0.0001), bilirubin (HR 1.39; 95% CI 1.11-1.75; p = 0.004), age (HR 1.06 95% CI 1.02-1.11; p = 0.005), international normalized ratio (HR 3.49; 95% CI 1.36-8.97; p = 0.010), and albumin (HR 0.18; 95% CI 0.09-0.37; p = 0.0001).
Adenoviral delivery of truncated MMP-8 fused with the hepatocyte growth factor mutant 1K1 ameliorates liver cirrhosis and promotes hepatocyte proliferation.
The following were associated with a significantly higher rate of liver complications: age; birth in Asia, Europe, Mediterranean region, or Egypt; transmission by blood transfusion or sporadic cases; HCV genotypes 1b and 4 (compared with 1/1a); fibrosis stage 3 or 4 (cirrhosis); serum albumin; bilirubin; prothrombin time; and alpha-fetoprotein.
Univariate and multivariate logistic regression analysis revealed significant association of low albumin (<3.5), cirrhosis and Fib-4 score (>3.25) with treatment failure.
This results in a group of diseases termed the serpinopathies, which are typified by mutations of α(1)-antitrypsin and neuroserpin in association with cirrhosis and the dementia familial encephalopathy with neuroserpin inclusion bodies, respectively.
Liver injury resulting from this gain-of-toxic function mechanism in which mutant AAT retained in the ER initiates a series of pathologic events, eventually culminating at liver cirrhosis and HCC.
HFE and alpha-1 antitrypsin polymorphisms were characterized in 200 Egyptian patients with HCV infection (100 patients complicated with cirrhosis, 100 patients with HCC) and 100 healthy subjects who had no history of any malignancy.
Logistic regression analysis identified male sex, age, serum ferritin and TGF-beta1 codon 25 Arg/Pro and Pro/Pro as independent predictors for the presence of cirrhosis.
Productive infections have been achieved recently with genotype 2a virus, but cirrhosis and liver cancer are typically associated with genotype 1 HCV, which is more prevalent and relatively resistant to IFN therapy.
