Treatment of chronic hepatitis B with the sequential administration of interferon and lamivudine

BACKGROUND/AIMS: Interferon monotherapy has been shown to induce a sustained viral response in 30-40% of patients with HbeAg-positive chronic hepatitis B infection. Similarly, lamivudine monotherapy causes HBeAg seroconversion in less than 20% of patients treated for one year. This study aims to assess the efficacy and safety of the sequential administration of interferon alfa-2a plus lamivudine to patients with chronic hepatitis B in comparison to lamivudine monotherapy. METHODOLOGY: Sixty-one patients with HbeAg-positive chronic hepatitis B infection and raised ALT were randomized to receive either interferon Alfa-2a, 4.5 million units daily for 16 weeks plus lamivudine 100 mg daily starting from week 5 and continuing for 48 weeks (Group A, n = 32) or lamivudine monotherapy for 48 weeks (Group B; n = 29). Patients were followed for 48 weeks after completion of therapy. RESULTS: HBeAg seroconversion to anti-HB +ve was observed in 2 (6.2%) patients in Group A. Both patients remained HBeAg negative and HBV-DNA negative throughout the follow-up phase. None of the group B patients seroconverted at the end of therapy or during follow-up (P = NS). All group A patients experienced at least one side effect and as a result, one dropped out. All group B patients completed the study without side effects. CONCLUSIONS: The sequential administration of interferon plus lamivudine was not superior to lamivudine monotherapy for the treatment of chronic hepatitis B and was associated with more side effects.

Methylprednisolone acetate versus oral prednisolone in moderately active ulcerative colitis.

BACKGROUND: Patients with active ulcerative colitis are treated with corticosteroids. We compared the efficacy and safety of intramuscular depot preparation of methylprednisolone acetate with oral prednisolone in the treatment of moderately active ulcerative colitis. DESIGN: Open labeled, randomized, prospective, four-month study. METHODS: 40 patients with moderately active ulcerative colitis (activity index 150-220) were randomized into two groups. Group A (n=21) received methylprednisolone acetate (80 mg intramuscularly once weekly for 6 weeks). Group B (n=19) received oral prednisolone (40 mg/day) in a 'tailing-off' regimen. In addition, patients in both the groups received sulfasalazine. Patients were followed up at 1, 2, 3, 4, 8, 12 and 16 weeks. The primary measure of therapeutic response was activity index. An index of <150 was considered as clinical remission. Secondary efficacy was assessed by subjective evaluation of acceptability of treatment by the patient. RESULTS: After one week of treatment, the decrease in mean activity index was significantly more with oral prednisolone (p<0.05), and five 5 patients (23.8%) in Group A and 12 (63.2%) in Group B were in clinical remission (p<0.05). However, after 2 weeks and beyond, the mean activity index and the number of patients with clinical remission were comparable in the two treatment groups. CONCLUSIONS: Methylprednisolone acetate as a depot preparation and oral prednisolone are equally effective in inducing remission in patients with moderately active ulcerative colitis. Though symptomatic improvement is quicker with oral prednisolone, the remission rate with the two drugs was similar after 2 weeks of treatment.

Impact of shorter duration of treatment on virological response rate in genotype 2 or 3 chronic hepatitis C virus infection.

OBJECTIVE: To evaluate the effect of shortened duration of pegylated interferon (PEG-IFN) and ribavirin (RIB) treatment on sustained virological response (SVR) rates in treatment-naomicronve patients with chronic hepatitis due to genotype 2 or 3 hepatitis C virus (HCV) infection and high pre-treatment viral load (>800,000 IU/mL). METHODS: Records of 142 patients with chronic hepatitis C (22 with cirrhosis) who had been treated with PEG-IFN and RIB for 24 weeks (Group A, n=88), both drugs for 12-16 weeks (Group B, n=39), or with PEG-IFN for 12-16 weeks and RIB for 24 weeks (Group C, n=15), were analyzed retrospectively. RESULTS: Overall, 81.7% of patients had SVR (Group A: 88.6%, Group B: 69.2% and Group C: 73.3%, p=0.02). Failure to achieve SVR was significantly related to treatment group (p=0.026 for Group B and p=0.002 for Group C, versus Group A), older age (p=0.023), higher liver biopsy stage (p=0.001) and presence of cirrhosis (p< 0.0001). In patients without cirrhosis, only the treatment group (p=0.018 for Group B and p=0.002 for Group C, compared to Group A) independently predicted failure to achieve SVR. CONCLUSION: Shorter duration of PEG-IFN treatment (12-16 weeks) adversely affected the SVR rate in patients with genotype 2 or 3 HCV infection. However, increasing the duration of RIB administration (12-16 weeks versus 24 weeks) in such patients did not have any beneficial effect on SVR in patients receiving short-duration PEG-IFN.     

Clinical outcomes of metallic stent insertion for obstructive colorectal cancer

BACKGROUND/AIMS: As the treatment of acute malignant obstruction of the left colon, self-expandable metallic stent insertion has been clinically used with good results. The aim of this study is to analyze the outcome of planned operation after stent insertion for obstructive colorectal cancer. METHODOLOGY: From 2000 to 2003, among 37 patients treated for obstructive colorectal cancer, we compared hospital days and complications between Group A (n=18) and Group B (n=19). Group A included the patients who underwent planned operation after stent insertion and Group B included the patients who underwent planned operation after emergency temporary colostomy formation. RESULTS: In Group A, complications after stent insertion were perforation with abscess formation (n=1) and stent migration (n=2). Complications after definitive operation were not observed. In Group B, complications after temporary colostomy involed stoma site wound infection (n=2). Complications after definitive surgery were as follows: anastomotic leakage (n=1), pneumonia with acute renal failure (n= 1), wound infection (n=2). In group A and group B, hospital day after decompressive procedure was 5+/-4.0 days (range, 1-16 days) vs. 14+/-4.7 days (range, 7-27 days) (P=0.000). Hospital day after definitive operation was 11+/-4.0 days (range 8-22 days) vs. 16+/-9.2 days (range 10-41 days) (P=0.002). CONCLUSIONS: Because preoperative self-expandable metallic stent insertion for obstructive colorectal cancer had better postoperative results and shorter hospital days than emergent diverting colostomy, this procedure is a good "bridge to surgery".
