In this retrospective study, we aimed to share our experience with different treatment modalities for chronic hepatitis B in a series of children. The study included 126 children (mean: 9.5 +/- 3.8 years). Normalization of alanine aminotransferase (ALT), loss of hepatitis B virus (HBV)-DNA and hepatitis B e antigen (HBeAg), and development of antibody to HBeAg (anti-HBe) altogether at the end of the treatment was considered as end of therapy response (ETR). Seroconversion ongoing one year after the cessation of therapy was considered as sustained response. Of the total children, 90 (71.4%) were treated, whereas the remaining were just followed-up. High-dose interferon (IFN)-alpha (10 MU/m2) alone, standard-dose IFN-alpha (6 MU/m2) plus lamivudine (4 mg/kg/d), high-dose IFN-alpha plus lamivudine, or lamivudine alone was used, IFN-alpha thrice weekly for six months, and lamivudine daily for one year. Of children who had completed their treatment, 34 (37.8%) achieved ETR. Sustained response rate was 36.7%. Response rates were different in the different treatment groups (p: 0.01). The highest response rate was observed in those who received standard-dose IFN-alpha plus lamivudine treatment (61.5%). Of children without treatment, one (2.8%) had anti-HBe seroconversion. Standard-dose IFN-alpha plus lamivudine treatment was found superior to the other treatment modalities. Predictors of ETR were similar to those found in previous studies.

Optimal doses of Ribavirin (RBV) for hepatitis C virus (HCV) treatment are not known. To assess the safety and efficacy of PegIFNalfa-2a in combination with an adjusted (ADJ) RBV dose based on early pharmacokinetics versus a fixed standard (STD) dose of RBV in chronic HCV genotype (GT) 4-naive patients in a randomized trial. One hundred eighty-one patients were randomized.

To investigate the clinical effect and safety of long-acting pegylated interferon-α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 μg/week) in the treatment of HBeAg-positive chronic hepatitis B (CHB) patients, with standard-dose Peg-IFN-α-2a as positive control. This study was a multicenter, randomized, open-label, and positive-controlled phase III clinical trial. Eligible HBeAg-positive CHB patients were screened out and randomized to Peg-IFN-α-2b (Y shape, 40 kD) trial group and Peg-IFN-α-2a control group at a ratio of 2:1.

To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1.

Background: Despite local therapies, commonly transurethral resection (TUR) followed by adjuvant treatments, non-muscle-invasive bladder cancer (NMIBC) has a high rate of recurrence and progression. Intravesical Bacillus Calmette-Guérin (BCG) has been shown to reduce recurrence and progression in people with NMIBC following TUR, however many people do not respond to treatment, have recurrence shortly after, or cannot tolerate standard-dose therapy. The potential for synergistic antitumour activity of interferon (IFN)-alpha (α) and BCG provides some rationale for combination therapy for people who do not tolerate or respond to standard-dose BCG therapy.

Imatinib was the first signal transduction inhibitor (STI), used in a clinical setting. It prevents a BCR-ABL protein from exerting its role in the oncogenic pathway in chronic myeloid leukemia (CML). Imatinib directly inhibits the constitutive tyrosine kinase activity.
