Abstract
BACKGROUND/AIMS: Hepatitis B virus (HBV) induces inflammatory signaling leading to progressive liver damage. Polymorphisms of the toll-like receptor (TLR) 2 (Arg677Trp, Arg753Gln) and TLR4 (Asp299Gly, Thr399Ile) genes, which are important components of innate immunity against viral infection, have recently been described. We evaluated the association between TLR2 and TLR4 polymorphisms and the development of liver cirrhosis in Koreans with chronic HBV infection. METHODOLOGY: This study enrolled 456 Koreans with chronic HBV infection between December 2004 and October 2007; 242 with chronic hepatitis B (group I) and 214 with liver cirrhosis (group II). TLR2 and TLR4 polymorphisms were determined using direct sequencing. RESULTS: Mean age differed significantly between groups (group I, 34.8 +/- 11.4 years; group II 51.0 +/- 8.9 years; p < 0.001), whereas the proportion of males (80.2% vs. 73.4%, respectively; p = 0.085) and hepatitis B e antigen-positive patients (40.7% vs. 43.6%, respectively; p = 0.575) did not. The serum alanine aminotransferase level was significantly higher in group I (87.9 +/- 138.5 IU/L) than in group II (56.6 +/- 70.7 IU/L, p = 0.003). However, the TLR2 Arg677Trp and Arg753Gln and TLR4 Asp299Gly and Thr399Ile mutant alleles were not detected in any patients. CONCLUSIONS: The TLR2 Arg677Trp, Arg753Gln and TLR4 Asp299Gly, Thr399Ile mutant alleles were not detected in any patient, suggesting that they are very rare in the Korean population. Our results do not permit any conclusion regarding their role in the development of liver cirrhosis
