Second-line treatment for failure to eradicate Helicobacter pylori: a randomized trial comparing four treatment strategies.
AIM: To compare the efficacy of different regimens in patients in whom previous Helicobacter pylori eradication therapy has failed. METHODS: In this study named StratHegy patients (n=287) were randomized to receive one of three empirical triple therapy regimens or a strategy based on antibiotic susceptibility. The empirical regimens were omeprazole, 20 mg b.d., plus amoxicillin, 1000 mg b.d., and clarithromycin, 500 mg b.d., for 7 days (OAC7), clarithromycin, 500 mg b.d., for 14 days (OAC14) or metronidazole, 500 mg b.d., for 14 days (OAM14). In the susceptibility-based strategy, patients with clarithromycin-susceptible strains received OAC14, whilst the others received OAM14. The 13C-urea breath test was performed before randomization and 4-5 weeks after eradication therapy. RESULTS: In the intention-to-treat analysis, the eradication rates for empirical therapies were as follows: OAC7, 47.4% (27/57); OAC14, 34.5% (20/58); OAM14, 63.2% (36/57); it was 74.3% (84/113) for the susceptibility-based treatment (P<0.01 when compared with OAC7 and OAC14). In patients receiving clarithromycin, the eradication rates were 80% for clarithromycin-susceptible strains and 16% for clarithromycin-resistant strains; in patients receiving OAM14, the eradication rates were 81% for metronidazole-susceptible strains and 59% for metronidazole-resistant strains. CONCLUSIONS: Eradication rates of approximately 75% can be achieved with second-line triple therapy based on antibiotic susceptibility testing. If susceptibility testing is not available, OAM14 is an appropriate alternative.

Preoperative treatment of hepatocellular carcinoma with intra-arterial injection of 131I-labelled lipiodol.
BACKGROUND: Recurrence is common after surgery for hepatocellular carcinoma (HCC). METHODS: The efficacy of, and tolerance to, preoperative intra-arterial injection of (131)I-labelled lipiodol was examined in 34 patients with HCC, including 29 with cirrhosis. Twenty-five patients had a single hepatic tumour and the mean(s.d.) tumour size was 5.2(3.7) (range 2-15) cm. The patients received between one and three injections of (131)I-labelled lipiodol (60 mCi per injection) before surgery. Operations included 14 liver transplants, 13 minor hepatectomies, six major hepatectomies and one exploratory laparotomy. RESULTS: There was one complication after lipiodol injection due to acute ischaemia of the small bowel. Three of 34 patients died within 28 days, two after transplantation and one after resection. An objective tumour response (decrease in tumour size) was observed in 19 of 34 patients, and a complete histological response in eight of 34. There was an objective tumour response or major histological necrosis of lesions in 25 of 34 patients. The 5-year survival rate was 48.4(8.0) per cent, 69.0 per cent after transplantation and 36.0 per cent in patients who underwent resection. CONCLUSION: This preoperative method appeared to be well tolerated, and provided promising results in terms of macroscopic and microscopic tumour responses.
