This study was aimed to evaluate the long-term effects of
telbivudine (LdT) in the treatment of
chronic hepatitis B (CHB) and HBV-related
liver cirrhosis (LC) and to observe the changes of immunological responses during LdT treatment. Clinical data of 80 CHB and 28 HBV-related LC patients who were administered with LdT for 108 weeks and followed up were retrospectively analyzed. The liver function indicators including ALT, AST and γ-GT, HBV
DNA copy number in serum and the rates of
hepatitis B e antigen (
HBeAg) seroconversion were analyzed before and 12, 24, 36, 48, 60, 72, 84, 96 and 108 weeks after LdT treatment in CHB and LC groups. Four serum
fibrosis-related markers, including
hyaluronic acid (HA), human
laminin (LN), human
type IV collagen (IV-C) and human N-terminal
procollagen III
peptide (PC-III), were detected before and after LdT treatment in LC group. The results showed favorable viral suppression and biochemical responses
after treatment with LdT for 12 weeks, and a high rate of virological and biochemical control was maintained during the course of 108-week treatment in both CHB and LC groups. The four
fibrosis-related markers, especially HA and LN, were down-regulated to some degrees in LC group. Moreover, LdT treatment led to the fluctuation of the circulating
interferon-γ (IFN-γ) and
interleukin-10 (IL-10) levels at different time points in CHB group. It was concluded that LdT could favorably lead to the virological suppression and biochemical remission. Besides, IFN-γ and
IL-10 may represent a suitable and effective predictor of responsiveness during LdT
therapy.
