To evaluate the effect of interferon and the benefit of prednisolone pretreatment in Oriental patients with chronic active hepatitis B, 120 male Chinese patients were randomly allocated to receive: 1) group A: a 4-week course of prednisolone followed by 2 weeks of no treatment and then a 12-week course of human lymphoblastoid interferon, 4 to 6 MU/m2 intramuscularly; 2) group B: as group A, but with placebo given instead of prednisolone; 3) group C: an 18-week course of placebo. Clearance of serum hepatitis B virus-DNA and HBeAg (complete response) was achieved in 21% of group A, 5% of group B and none of group C at the end of therapy (A vs B: p = 0.054; A vs C: p < 0.01). When assessed 12 months after the end of therapy, the complete response rate was 46% in group A, 24% in group B and 25% in group C (p < 0.05). Those with baseline alanine transaminase < or = 200 U/l showed a better response to interferon following prednisolone withdrawal (48%) than with interferon therapy alone (20%, p = 0.056) and no treatment (9%, p < 0.01). Those with a baseline serum hepatitis B virus-DNA < or = 1000 pg/ml also showed a higher complete response rate when pretreated with prednisolone (59%) than when treated with interferon alone (29%, p = 0.084) or untreated (22%, p < 0.03). The strongest independent predictor of a response to treatment was prednisolone withdrawal (p < 0.05). None of the responders lost hepatitis B surface antigen.(ABSTRACT TRUNCATED AT 250 WORDS) There is no generally accepted treatment for chronic hepatitis B (HB) infection in children.
                To evaluate the efficacy of a prolonged course of high dose interferon alone or after prednisone priming in children with chronic HB infection.
                The outcome of 31 children with HB e antigen (HBeAg)-positive chronic hepatitis who randomly received either no treatment (n = 9) or 10 million units of interferon alpha-2b/m2, alone (n = 13) or after prednisone priming (n = 9), three times weekly for 1 year was studied.
                One patient withdrew from treatment. By the end of the first year treatment induced a loss of HB virus DNA and HBeAg from serum in 10 of 21 patients (48%), and a loss of HB surface antigen (HBsAg) in 4 (19%). Alanine aminotransferase values became normal in one patient (4.8%). Response rates in the two groups of treated patients were similar. In controls only one patient lost HBeAg and HBV DNA (11%; P = 0.05), and none lost HBsAg or showed alanine aminotransferase normalization (P = 0.21 and 0.70, respectively). After a posttreatment 2-year follow-up there were still no differences in the response rates of the two treatments; of the 21 pooled treated patients, 61% lost HBeAg and DNA and 67% normalized alanine aminotransferase (vs. 33 and 44% of controls, respectively; P = 0.32 and 0.40). Reversion to HBeAg and HBV DNA negativity in treated patients occurred significantly earlier (P = 0.02 and 0.006, respectively) than in controls. No further patient lost HBsAg, but one reacquired HBsAg. Treated patients had posttreatment histologic scores better than controls (P = 0.03).
                Our medium term follow-up results indicate that a prolonged course of high dose interferon in children with chronic HB infection, regardless of prednisone priming, poorly affects response rates but significantly speeds termination of active viral replication. Interferon is the most promising therapeutic agent for the treatment of chronic viral hepatitis. The results of studies suggest that corticosteroid pretreatment may improve the response rate. Twenty-nine children with chronic hepatitis B (CHB) were randomly assigned to receive recombinant interferon alpha (rIFN-alpha) alone (Group 1.5 million units/m2 body surface, 3 times a week for 24 weeks) or to receive oral prednisone (Group 2.2 mg/kg/day for 3 weeks, discontinued by tapering the dose within 1 week) followed by rIFN-alpha (same dose as above). Tests for liver function and hepatitis B virus (HBV) markers including HBV-DNA were done periodically. Overall, 10 patients (34.5%) cleared hepatitis Be antigen and 13 (44.8%) HBV-DNA. Anti-HBe seroconversion was observed in nine patients (31%). Only three patients (10.3%) cleared hepatitis B surface antigen and seroconverted to anti-HBs. No response was obtained in 11 patients (37.9%). There was no statistically significant difference between the two treatment groups regarding response rate. Baseline transaminases levels and HBV-DNA concentrations were predictive parameters for HBeAg clearance. It is concluded that prednisone pretreatment does not have a beneficial effect in children with CHB. The aim of this multicentre, randomised, controlled, clinical trial was to evaluate the effect of prednisolone followed by lymphoblastoid interferon treatment in chronic hepatitis B.
                Two hundred and thirteen patients with chronic hepatitis B were randomised to either prednisolone (2 weeks of 0.6 mg/kg/day, 1 week of 0.45 mg/kg/day and 1 week of 0.25 mg/kg/day) or matching placebo followed by a 2-week rest phase and then human lymphoblastoid interferon 10 MU daily for 5 days followed by 10 MU thrice weekly for 11 weeks. Of 200 evaluable patients, 33 (16.5%) were females, and 50 (25%) were male homosexuals. Thirty three patients (16.5%) had chronic persistent hepatitis, 145 (72.5%) had chronic active hepatitis and 22 (11%) had active cirrhosis.
                Survival analysis disclosed statistically significant effects of prednisolone pre-treatment on both HBeAg disappearance and HBeAg to anti-HBe seroconversion (log-rank test statistics 5.43; p = 0.02 and 4.75; p = 0.03). Observed HBeAg disappearance and HBeAg to anti-HBe seroconversion rates (placebo vs. prednisolone patients) were 28% vs. 44% and 23% vs. 38%. Six months after stopping interferon, HBV DNA was negative in 51% of prednisolone patients vs. 28% of placebo patients (Chi-square test statistic 6.13; p = 0.013). Prednisolone pre-treatment tended to be more effective in patients with higher transaminase levels and in patients with low levels of HBV DNA. Fifteen patients (7.5%) (13 within 1 year of follow-up) eventually lost HBsAg; 14 of these subsequently developed anti-HBs. Interferon treatment was modified in 102 patients (51%). Three out of 22 patients with cirrhosis (14%), one of whom received prednisolone pre-treatment, developed hepatic decompensation with a fatal outcome while on interferon treatment.
                Prednisolone pre-treatment significantly enhanced the treatment effect of lymphoblastoid interferon in terms of HBeAg clearance and seroconversion to anti-HBe. Treatment should be used with caution in patients with cirrhosis and avoided in patients showing signs, or with a history, of decompensated cirrhosis. Chronic hepatitis B is a common and often progressive liver disorder for which there is no accepted therapy. To assess the efficacy of treatment with interferon, we randomly assigned patients with chronic hepatitis B to one of the following regimens: prednisone for 6 weeks followed by 5 million units of recombinant interferon alfa-2b daily for 16 weeks; placebo followed by 5 million units of interferon daily for 16 weeks; placebo followed by 1 million units of interferon daily for 16 weeks; or observation with no treatment.
                Hepatitis B e antigen and hepatitis B viral DNA disappeared from serum significantly more often in the patients given prednisone plus interferon (16 of 44 patients, or 36 percent) or 5 million units of interferon alone (15 of 41; 37 percent) than in the untreated controls (3 of 43; 7 percent; P less than 0.001); the difference between those given 1 million units of interferon (7 of 41; 17 percent) and the controls was not significant. The strongest independent predictor of a response to treatment was the amount of hepatitis B viral DNA in serum at entry (P less than 0.0001). Of the 38 patients who responded to interferon, 33 (87 percent) had normal serum aminotransferase levels after therapy; 11 patients who responded (29 percent), but no controls, lost the hepatitis B surface antigen. Blinded histologic assessment revealed a significant improvement in periportal necrosis in the treated patients (P = 0.03).
                In chronic hepatitis B, treatment with interferon alfa-2b (5 million units per day for 16 weeks) was effective in inducing a sustained loss of viral replication and achieving remission, assessed biochemically and histologically, in over a third of patients. Moreover, in about 10 percent of the patients treated with interferon, hepatitis B surface antigen disappeared from serum. Ninety Chinese hepatitis B surface antigen (HBsAg) carrier children, aged 2-17 years, positive for hepatitis B e antigen (HBeAg) and hepatitis B virus DNA on at least three occasions in 6 months, were randomized into 3 groups. Thirty children received syrup vitamin B complex as control, 29 received 6 weeks of placebo syrup followed by 16 weeks of recombinant alpha 2b-interferon [intron A (rIFN2b)], 5 x 10(6) u/m2 subcutaneously thrice weekly; and 31 received 6 weeks of syrup prednisone (0.6 mg/kg tailed to 0.2 mg/kg) followed by 16 weeks of recombinant alpha 2b-interferon as above. The placebo/prednisone syrup was given on a double-blind basis. At 24 months of follow-up, persistent loss of hepatitis B virus DNA occurred in none of the children in the control group, in one child receiving recombinant alpha 2b-interferon alone, who also seroconverted to anti-HBe and anti-HBs and in five children receiving interferon with steroid priming (p = 0.0571 compared with controls), with four seroconverting to anti-HBe and one also seroconverting to anti-HBs. A rise of transaminases to above twice the upper limit of normal levels during the first 7 months of follow-up occurred in one subject in the control group, four in the group receiving alpha 2b-interferon alone and nine in the group receiving recombinant alpha 2b-interferon with steroid priming (p = 0.0144 compared with controls). Side effects of the steroid were negligible; those of recombinant alpha 2b-interferon were transient and acceptable. We conclude that 6 weeks of prednisone followed by 16 weeks of recombinant alpha 2b-interferon is of use in inducing persistent loss of hepatitis B virus DNA (16.1 per cent) and e-seroconversion (12.9 per cent) in a proportion of Chinese HBsAg carrier children: the prednisone probably enhances the immunomodulatory effect of recombinant alpha 2b-interferon. In a randomized, controlled trial of recombinant interferon alfa-2b with or without prednisone priming in Chinese adults with chronic hepatitis B virus infection, stratified randomization for pretreatment serum alanine aminotransferase levels was done. Partial or complete antiviral responses were achieved in 17 (21.5%) of 79 treated patients and 3 (8.3%) of 36 controls (P = 0.14). The response to interferon treatment was significantly better in those who had elevated pretreatment transaminase levels and comparable to that reported in white patients [15 (38.5%) of 39 patients compared with 2 (5%) of 40 who had normal pretreatment transaminase levels (P = 0.0005)]. The spontaneous seroconversion rate was also higher among the controls with elevated transaminase levels [3 (18.8%) of 16 compared with 0 of 20 with normal transaminase levels], but this difference was not statistically significant (P = 0.16). Among the interferon-treated patients, prednisone priming appeared to have a marginal benefit over treatment with interferon alone in patients with elevated transaminase levels (43% vs. 33%), but not in those with normal transaminase levels (0% vs. 9.5%). It was confirmed that Chinese patients with normal transaminase levels respond very poorly to interferon alfa therapy. However, the response was significantly better in patients with elevated transaminase levels. Thirty-five children with chronic HBV infection, HBV-DNA and eAg serum positivity, and HBcAg in liver tissue were treated with lymphoblastoid human interferon alpha with (16 cases) or without (19 cases) prednisolone pretreatment. The patients were double-blind randomized to receive steroid or placebo for 4 weeks, followed after 2 weeks by 5 or 10 MU/m2 interferon for 12 weeks. The e anti-e seroconversion rate reached 48%, which is much higher than the spontaneous seroconversion rate. The influence of "prednisolone priming" was not statistically significant. HBeAg clearance was similar in both groups (44% after prednisolone/interferon and 53% after interferon alone). The response to either treatment did not correlate with the pretreatment serum transaminase. HBV-DNA or degree of histological activity. Interferon was well tolerated, the side effects being less severe than in adults, and never led to suspension of the treatment. The comparative efficacy of prednisolone followed by interferon alfa (IFN-alpha) versus IFN-alpha alone in enhancing the rate of antibody to hepatitis B e antigen (anti-HBe) seroconversion has not been evaluated in a large cohort of white children. To determine this, a multicenter-controlled trial was conducted in 95 hepatitis B virus (HBV)-DNA/hepatitis B e antigen (HBeAg)-positive children (median age, 9 years [range, 2-16 years]; 56 boys; 84 [89 percent] white), all having inflammatory changes on liver biopsy. Patients were randomized to receive either prednisolone followed by IFN-alpha (n = 34); placebo followed by IFN-alpha (n = 30); or no treatment (n = 31). The prednisolone/placebo was given on a double-blind basis. Lymphoblastoid IFN-alpha was given at 5 MU/m(2) three times a week for 12 weeks. Baseline clinical, biochemical, and histological features were similar for the three groups. The majority (85 percent) had a baseline aspartate aminotransferase (AST) level < or = 100 IU/L. On follow-up between 12 and 18 months (median, 15 months) after treatment, the loss of HBeAg with anti-HBe seroconversion was more common in patients pretreated with steroids (12 of 34 [35 percent]) or placebo [12 of 30 (40 percent)] as against controls (4 of 31 [13 percent], P< .05). Factors predictive of anti-HBe seroconversion were baseline HBV-DNA concentration of < or = 1,000 pg/mL and a greater degree of portal tract inflammation on pretrial biopsy. Our results show that in white children treatment with IFN-alpha, at the dose and duration used in this study, improves the rate of anti-HBe seroconversion. Steroid priming does not potentiate the effect of IFN-alpha. Fifty-six patients with biopsy-proven, chronic active hepatitis B were included in a multi-center, randomized trial comparing steroid withdrawal followed by 1.5 MU recombinant interferon alpha 2b (Intron) with placebo withdrawal followed by either 1.5 or 5 MU interferon. The patients were equally distributed between the treatment groups with respect to biochemical and histologic activity as well as with respect to DNA levels and quantitative liver function tests. One patient was lost to follow up. After 1 year of treatment, 10/18, 13/19 and 11/18 patients had lost hepatitis B virus DNA in the three groups, respectively (non-significant). Transaminase levels were normal in 27/34 of the responders but in only 4/21 of the non-responders (p < 0.0001). Both galactose elimination capacity and aminopyrine breath test improved significantly in responders, but either did not change (aminopyrine breath test) or deteriorated in non-responders (galactose elimination capacity). Biopsy score improved in both groups but this reached statistical significance only in responders. This effect was due to improvements in both inflammatory and fibrotic activity. Side effects included almost universally a flu-like syndrome, granulocytopenia (1), depression (3) and thyroid dysfunction (2). Two deaths occurred, one due to hepatocellular cancer, and the other to hepatorenal syndrome after spontaneous bacterial peritonitis. A severe cytolytic episode was observed in three patients in the steroid withdrawal group. We conclude that in patients with marked histologic activity, lower doses of interferon may be as effective as the standard dose of 5 MU.(ABSTRACT TRUNCATED AT 250 WORDS) This study was designed to evaluate the safety and effectiveness of high dose interferon, with or without prednisone pretreatment, in patients with chronic hepatitis B. Patients were randomised to two treatment groups: group I (n = 26) received six weeks of prednisone followed by a two week, drug free period, and then 10 million units (MU) of interferon alfa-2b three times weekly subcutaneously for 16 weeks; group II (n = 24) were used as controls for 24 weeks and then treated with interferon. Loss of hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV)-DNA, with a return to normal alanine aminotransferase (ALT) activity, was seen in 16 of 26 group I patients (61.5%), in one group II patient (4.2%) during the control phase, and in 13 of 23 group II patients (56.5%) after interferon. Three of 26 (11.5%) in group I and one of 23 (4.3%) in group II eliminated the surface antigen (HBsAg). There were no statistically significant differences in response between groups I and II. Liver biopsies carried out in 20 patients showed that responders had a noticeable reduction in inflammation and disappearance of core antigen in liver tissue, changes not seen in non-responders. On long term follow up (four years), nine out of 28 responders (32.1%) eliminated HBsAg, and four initial non-responders had a late seroconversion. The present study was aimed to test the efficacy and safety of interferon alpha (Wellferon-Wellcome Foundation Ltd.) either alone, or in combination with short-term corticosteroid pretreatment in the therapy of chronic hepatitis B. 44 patients with documented chronic hepatitis type B (12 women and 32 men; mean age 37.5 years, range 23-59 years) and satisfying the entry criteria were subjects of the study. 30 patients had chronic active hepatitis on liver biopsy, while 14 had chronic persistent hepatitis. Consecutive patients were given either placebo or prednisone in a double-blinded manner for 4 weeks (0.6 mg/kg/day in the first two weeks, 0.45 mg/kg/day in the third week and 0.25 mg/kg/day in the last week), and then, after a 2 week pause, therapy with interferon was instituted for a total of 12 weeks. Interferon was given by intramuscular injection in a single daily dose of 10 x 10(6) IU for 5 days and three times weekly thereafter. However, because of side effects, the dose of interferon was occasionally reduced to 5 x 10(6) IU in most patients. Interferon induced a sustained cessation of HBV replication as judged by loss of DNA-polymerase activity in 26 (59%) patients, 20 (45%) patients seroconverted to anti-HBe. Additionally, 6 (14%) cases lost HBsAg and seroconverted to anti-HBs. Prednisone pretreatment did not seem to improve the efficacy of interferon therapy. The outcome of the treatment was unrelated to gender and pretreatment activity of transaminases, however, patients with low activity of HBV replication were more likely to respond to therapy than patients with high HBV replication.
