Does Helicobacter pylori eradication depend on the period of amoxicillin treatment? A retrospective study.
    Journal of gastroenterology, 1998, Volume: 33, Issue:1

    In this study, the effect of different periods of amoxicillin (AMPC) treatment on the eradication rate of Helicobacter pylori in 173 patients with peptic ulcers (gastric ulcer, 109; duodenal ulcer, 64) was investigated. AMPC (1.5 g/day) was administered for 2, 4, or 6 weeks with omeprazole (20mg/day) and plaunotol (240mg/day), a mucoprotective drug, for 8 weeks. The H. pylori eradication rate was 46.7% for 2 weeks' treatment, 83.4% for 4 weeks' treatment, and 100% for 6 weeks' treatment. The eradication rate had a good correlation with the period of AMPC treatment. The healing rates of peptic ulcer at 4 and 8 weeks were 93.3% and 100%, respectively, in the 2-week group, 98.0% and 99.3% in the 4-week group, and 85.7% and 100% in the 6-week group. The recurrence rate of gastric and duodenal ulcers was 3.5% and 0% respectively, in the patients in whom H. pylori was eradicated and 30.0% and 40%, respectively, in the patients in whom H. pylori was not eradicated for 12 months after the H. pylori eradication treatment. Adverse effects of this regimen were observed in 5 (2.9%) of the 173 patients. Diarrhea was observed in 3 patients and eruption in 2. These adverse effects disappeared within a few days after only AMPC was withdrawn. Therefore, these may be caused by AMPC. The eradication rate of H. pylori depends on the period of AMPC treatment. This regiment, AMPC (1.5g/day) + omeprazole (20mg/day) + plaunotol (240mg/day), is safe and well tolerated for eradication of H. pylori.

Effect of plaunotol on hypergastrinemia induced by long-term omeprazole administration in humans.
    Digestive diseases and sciences, 1995, Volume: 40, Issue:1

    Omeprazole markedly inhibits basal and stimulated gastric acid secretion and has the ability to produce hypergastrinemia and hyperplasia of enterochromaffin-like cells in humans. On the other hand, plaunotol, an acyclic diterpene alcohol, has been reported to inhibit gastrin release by stimulating endogenous secretion release. We investigated the effect of plaunotol on serum gastrin levels after six to eight weeks of omeprazole (20 mg/day) administration in 22 patients (16 males, 6 females; mean age 52.3, range 36-70 years) with peptic ulcer disease. The patients were randomized to the following two groups: 11 subjects with omerprazole alone (single group) and 11 with omeprazole plus plaunotol (240 mg/day) (combination group) treatment. There were no significant differences between the two groups concerning age, sex, ulcer stage, ulcer history, environmental factors, and Helicobacter pylori (HP) prevalence. After complete drug(s) administration, serum immunoreactive (ir) -gastrin levels increased significantly in the single group (P < 0.001) in contrast to the combination group, and plaunotol significantly inhibited hypergastrinemia induced by omeprazole administration (P < 0.001). Significant increases in serum ir-calcitonin gene-related peptide concentrations were observed in the combination group compared to the single group (P < 0.05). However, there were no significant changes in sereum ir-secretin, somatostatin, and vasoactive intestinal polypeptide levels as well as ulcer healing and HP prevalence between the two groups. These findings suggest that plaunotol may suppress hypergastrinemia induced by long-term omeprazole administration, at least partly, via a certain brain-gut hormone affecting gastrin release.

Eradication of Helicobacter pylori in patients with end-stage renal disease under dialysis treatment.
    American journal of kidney diseases : the official journal of the National Kidney Foundation, 1997, Volume: 29, Issue:1

    The efficacy and safety of combination therapy with amoxicillin, lansoprazole, and plaunotol for the eradication of Helicobacter pylori in patients on dialysis were evaluated. The study subjects comprised 15 dialysis patients in whom H pylori had been found in the gastric mucosa. The patients were given 500 mg amoxicillin once a day for 3 weeks, 30 mg lansoprazole once a day for 8 weeks, and 80 mg plaunotol three times a day for 24 weeks. Endoscopy was performed on entry and at 4 and 24 weeks after cessation of amoxicillin. The concentrations of serum gastrin and gastric juice ammonia also were measured. Fourteen patients completed the treatment protocol, one having dropped out because of nausea and diarrhea. H pylori was eradicated in 11 of the 14 patients 4 weeks after the end of amoxicillin therapy (eradication rate, 78.6%). All but one patient was free of H pylori 24 weeks after the amoxicillin was discontinued. Patients who became negative for H pylori had significantly decreased serum gastrin and gastric juice ammonia concentrations. Our findings indicate that a combination of amoxicillin, lansoprazole, and plaunotol can be used to eradicate H pylori in patients on dialysis.

Evaluation of a new bismuth-free triple therapy in nude mice and humans.
    European journal of gastroenterology & hepatology, 1995, Volume: 7 Suppl 1

    To evaluate the efficacy of a new triple therapy (amoxycillin, metronidazole, plaunotol) in eradicating Helicobacter pylori in a nude mouse model and in humans.. In an animal study we used 215 nude mice infected with H. pylori to assess the ability of single, dual and triple therapy to eradicate H. pylori from the mouse stomach. The number of H. pylori in the mouse stomach and extent of the gastritis was assessed from 1 to 4 weeks after treatment. In a human study, we enrolled 78 H. pylori-positive patients with recurrent peptic ulcer diseases, 29 of whom were given triple therapy (amoxycillin and metronidazole for 1 week and plaunotol for 4 weeks). Patients in the control group (n = 49) were given a histamine H2-receptor antagonist. All patients were assessed 5 and 11 months after completion of therapy.. In the mouse model, both the number of H. pylori and the gastritis score were significantly lower in the triple therapy group than in any other treatment group assessed 1-4 weeks after completion of therapy. In the human study, the triple therapy eradicated H. pylori from the stomachs of 25 out of 29 patients (86%), compared to the control group in which none of the 49 patients were free of H. pylori in the stomach 11 months after completion of therapy. There were no reported side effects with this triple therapy. None of the H. pylori-eradicated patients showed a recurrence of peptic ulcer disease; three of the four patients whose H. pylori was not eradicated by triple therapy showed a peptic ulcer recurrence within the study period, whereas 16 out of 49 patients in the control group had a peptic ulcer recurrence.. This new triple therapy was effective in the eradication H. pylori, had very few side effects and greatly reduced the rate of recurrent peptic ulcers.
