Abstract:
Objective To explore relationship between different HBV genotypes and peripheral blood follicular helper T lymphocyte (Tfh) and interleukin-21 (IL-21) and its significance in patients with HBV-induced hepatic cirrhosis.Methods HBV genotypes were tested in 59 cases of cirrhotic hepatitis B with positive human leukocyte antigen (HLA)-A2,differences of Tfh and IL-21 between patients infected with genotype B and genotype C were compared and its significance was investigated.Results In 59 cases of cirrhotic hepatitis B,36 cases (61.02%) were infected with genotype C,22 cases (37.29%) were infected with genotype B and 1 case (1.69%) was infected with genotype B and C.Peripheral blood Tfh level of genotype C was(2.89% ± 1.44%),lower than that of genotype B (4.65% ± 1.37%),t =3.01,P <0.01,IL-21 level of genotype C was (14.62 ± 2.12 ng/L),lower than that of genotype B (32.27 ± 11.25ng/L),t =4.12,P <0.01,HBV specific cytotoxic T lymphocyte(CTL)level of genotype C was (0.17% ±0.02%),lower than that of genotype B(0.37% ±0.03%),t =3.12,P <0.01,HBV DNA level of genotype C was (6.95 ± 0.75log10copies/ml),higher than that of genotype B (5.02 ± 0.36 log10 copies/ml),t =3.03,P < 0.01.Conclusion Compared with cirrhotic hepatitis B patients infected with genotype B,peripheral blood Tfh level of patients infected with genotype C was lower,causing lower IL-21 level and lower HBV specific CTL level,which result in higher HBV DNA level.
