TLR3 and TLR4 SNP variants in the liver disease resulting from hepatitis B virus and hepatitis C virus infection.

TLR3 and TLR4 SNP variants in the liver disease resulting from hepatitis B virus and hepatitis C virus infection. Br J Biomed Sci. 2018 Nov 13; Authors: Sghaier I, Zidi S, Mouelhi L, Ghazoueni E, Brochot E, Almawi WY, Loueslati BY Abstract BACKGROUND: Chronic infection with hepatitis B (HBV) and C virus (HCV) is linked with a pro-inflammatory state, predisposing to cirrhosis and liver cancer, particularly hepatocellular carcinoma (HCC). A role for toll-like receptor (TLR) signalling in hepatocarcinogenesis was recently documented. We hypothesised a link TLR3 and TLR4 polymorphisms and HCC, as surrogates for the significance of TLR signalling in the promotion and initiation of HCC. MATERIALS &METHODS: We recruited 174 HCV-infected patients, 100 HBV-infected patients, and 360 healthy control subjects. TLR3 (rs3775290) and TLR4 (rs4986790) genotyping was done by PCR-restriction fragment length polymorphisms (PCR-RFLP), LFTs and AFP by standard routine techniques. Liver fibrosis was assessed clinical by the Fibrotest and Actitest. RESULT: The TLR3 rs3775290 minor T genotype was linked with increased risk of chronic HBV (P = 0.05) and HCV (P = 0.031) infection. The TLR4 rs4986790 minor G genotype was linked with significantly increased risk for HBV/HCV chronic infection (P

Conclusions: While there is a certain overlap between the results of the current study and published transcriptomic profiles of non-transplanted livers with steatosis, we have identified discrete characteristics of the non-alcoholic fatty liver disease in liver grafts potentially utilizable for the establishment of predictive signature. Introduction Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in industrialized countries, its prevalence being estimated at 19–31.3% (1). It encompasses a range of conditions that are thought to arise from fatty liver (simple steatosis) throu...

In humans, almost 50% of all intrahepatic lymphocytes are NK cells that are strongly imprinted in a liver-specific manner and show a broad spectrum of cellular heterogeneity. Hepatic NK (he-NK) cells play key roles in tuning liver immune response in b...

Conclusion: In conclusion, Baishouwu extract exhibited potent effect on the development of HCC by altering TLR4/MyD88/ NF-κB signaling pathway in the sequence of hepatic inflammation-fibrosis-cancer, which provided novel insights into the mechanism of Baishouwu extract as a candidate for the pretreatment of HCC in the future. Introduction Hepatocellular carcinoma (HCC) is the fifth most common cancer in the world and the third cause of cancer-related deaths (Jemal et al., 2011). Chronic inflammation, caused by chemical, biological and physical factors, is found to be related to certain human cancers. The effe...

Conclusion: IL-2 receptor expression demonstrated the highest diagnostic accuracy, while the peripheral eosinophil count was the only marker tested in more than one study. Presently, liver biopsy remains superior to noninvasive diagnostic biomarkers as most studies exhibited inferior designs, hindering possible translation into clinical application. Introduction Liver transplantation (LT) exhibits 20-year survival rates of up to 50% (1) and is of great clinical importance. LT is the treatment of choice for acute or acute-on-chronic liver failure, while organ replacement therapies are still waiting for the break (2)...

Background: Hepatocellular carcinoma (HCC) accounts for 90% of primary hepatic malignancies. With the exception of chronic hepatitis B (CHB), other etiologies of chronic liver disease require progression to cirrhosis before HCC development. Case reports have described HCC in noncirrhotic patients with hepatitis C (HCV) and nonalcoholic fatty liver disease. Goal: The aim of this study was to determine the prevalence of patients without cirrhosis and CHB who developed HCC among a large cohort of HCC patients and to identify independent variables that are associated with no cirrhosis among patients with HCC. Study: Fr...

ConclusionsWhen the liver diseases advance to cirrhosis, the incidence of HCC is markedly increased. The development of HCC must be closely monitored by ultrasonography, magnetic resonance imaging, and computed tomography, irrespective of the different kinds of liver diseases.

Authors: Desai A, Sandhu S, Lai JP, Sandhu DS Abstract Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, which in turns accounts for the sixth most common cancer worldwide. Despite being the 6th most common cancer it is the second leading cause of cancer related deaths. HCC typically arises in the background of cirrhosis, however, about 20% of cases can develop in a non-cirrhotic liver. This particular subgroup of HCC generally presents at an advanced stage as surveillance is not performed in a non-cirrhotic liver. HCC in non-cirrhotic patients is clinically silent in its early stages ...

Conclusion: The major HCV genotype observed was 3 which is difficult to treat with direct-acting antivirals, owing to the more rapid progression of liver disease, increased rates of steatosis (non-alcoholic fatty liver disease), a higher risk for cancer (HCC). We believe this study is the first one to address the prevalence of mixed genotypes and untypeable genotype from India.

Conclusions: There is predominance of male patients with a mean age of 58.3 years. Degree ≤ II is the most frequent to the Edmondson-Steiner histological classification in the evaluated casuistic. HCV, ALD and NAFLD is the most common etiological agents found in the study. The (high) underestimated prevalence of NAFLD in the pre-transplanted patients is due to the fact that all patients presented cirrhosis, masking NAFLD signals. PMID: 30360608 [PubMed - in process]
