In this randomized, multicenter trial, we evaluated the effectiveness and side effect profile of a modified omeprazole-based triple therapy to cure Helicobacter pylori infection. The control group consisted of patients treated with standard dual therapy comprising omeprazole and amoxicillin. One hundred and fifty-seven H. pylori infected patients with duodenal ulcers were randomly assigned to receive either a combination of omeprazole 10 mg, clarithromycin 250 mg and metronidazole 400 mg (OCM) given three times daily for 10 days (n = 81), or a combination of omeprazole 20 mg and amoxicillin 1 g (OA) given twice daily for 14 days (n = 76). Prior to treatment and after 2 and 6 weeks, gastric biopsies from the antrum and corpus were obtained for histology and H. pylori culture. H. pylori infection was cured in 97.4% after OCM and in 65.8% after OA in the per-protocol analysis (p < 0.001) (intention-to-treat analysis: 93.4% and 63.2%, respectively). H. pylori was successfully cultured in 122 patients (77%). The overall rate of metronidazole resistance was 19.7% (24/122), no primary resistance to clarithromycin or amoxicillin was found. In the OCM group, all patients infected with metronidazole-sensitive H. pylori strains (n = 51) and those infected with strains of unknown susceptibility to metronidazole (n = 14) were cured (100%), while 77% (10/13) of those harboring metronidazole-resistant strains were cured of the infection (p = 0.36). Side effects leading to premature termination of treatment occurred in 2.5% of the patients in the OCM group and in 1.4% of the OA group. We conclude that combined treatment with omeprazole, clarithromycin and a higher dose of metronidazole is highly effective in curing H. pylori infection, and that this regimen remains very effective in the presence of metronidazole-resistant strains.

Gastric mucosal histamine content, enterochromaffin-like cell density, and mast cell density were studied in 13 subjects under omeprazole therapy, 13 partially gastrectomized subjects with a Billroth II reconstruction, 10 partially gastrectomized subjects with a Roux-en-Y reconstruction, and 9 control subjects. Histamine content was significantly greater both in the subjects with higher gastrinemic levels (omeprazole-treated subjects) and those with more abundant enterogastric reflux (Billroth II subjects) than in controls. Enterochromaffin-like cell density was significantly greater in the omeprazole subjects than in each of the other groups. Mast cell density was significantly greater in Billroth II subjects than in controls. Serum gastrin levels, mucosal histamine content, and enterochromaffin-like cell density were positively correlated. Gastrin was not correlated to mast cell density. These results support the existence of different control pathways for enterochromaffin-like and mast cells. Moreover, they suggest that enterochromaffin-like cells and mast cells are involved in the regulation of gastric secretion and in gastric mucosal injury-repair mechanisms, respectively, due to histamine release.

Despite 30 years of its discovery, the ideal therapeutic regimen against Helicobacter pylori is still evasive. Clarithromycin-based standard triple therapy which has been considered the first line empirical therapy has been failing in many parts of the world, due to rising resistance against Clarithromycin, forcing the use of alternate regimens. In this context, we studied the local antibiotic resistance patterns against H. pylori and its impact on standard triple therapy in our region. All patients undergoing diagnostic upper endoscopy during the study period and detected to be positive for rapid urease test (RUT) underwent cultures of gastric mucosal specimens and had their antibiotic resistance patterns mapped out. Standard triple therapy was administered to those tested positive for H. pylori by RUT and eradication rates checked by urea breath test 4 weeks after the completion of treatment. Eradication rates with Clarithromycin-based standard triple therapy were suboptimal with a success of only (71.28%). H. pylori culture and antibiotic susceptibility studies showed high resistance to Clarithromycin (21.2%), Metronidazole (78.1%), and Levofloxacin (15%). However, the resistance to Amoxicillin (2.9%), Tetracycline (0%), and Rifabutin (4.5%) were low. Standard triple therapy is failing in our region due to high Clarithromycin resistance. We need to abandon empirical and blind triple therapy without post-treatment testing and devise alternate effective treatment strategies against H. pylori based on the local resistance patterns observed.

Diazepam was more slowly metabolized in the poor metabolizers than in the extensive metabolizers. No significant effects of E3810 and omeprazole on any kinetic parameters of diazepam were observed in the poor metabolizers. In the extensive metabolizers, omeprazole significantly decreased the mean clearance of diazepam and increased its half-life, area under the plasma concentration-time curve, and mean residence time compared with E3810 and placebo (p < 0.05 or 0.01), whereas no changes in these kinetic parameters were observed during the treatment with E3810. Omeprazole significantly increased the mean area under the plasma concentration-time curve (0-16 days) of demethyldiazepam in the extensive metabolizers compared with placebo (p < 0.01), whereas E3810 significantly increased it in the poor metabolizers compared with omeprazole or placebo (p < 0.05).
A case-control study was undertaken to identify and quantify antimicrobial and nonantimicrobial drug risk factors associated with a sustained outbreak of Clostridium difficile diarrhea on two medical (teaching and nonteaching) units and an oncology unit. In total, 80 cases associated with an endemic clone of toxigenic C difficile were compared with controls. Eighty controls were selected from a group of 290 controls randomly chosen from the outbreak period. The controls were matched to cases according to age, admitting diagnosis and unit of admission. Seventy (88%) patients in the case group received at least one antibiotic before diarrhea, compared with 37 (46%) patients in the control group. Major risk factors implicated in the development of C difficile diarrhea in hospitalized patients were the following antimicrobial agents: ceftazidime (adjusted odds ratio [aor]=26.01, 95% ci 5.67 to 119.19, P=0.0001); cefuroxime (aor=5.17, ci 1.86 to 14.36, P=0.005); ciprofloxacin (aor=3.81, ci 1.05 to 13.79, P=0.04); and clindamycin (aor=15.16, ci 2.93 to 78.44, P=0.004). This is the first time that the use of ciprofloxacin has been linked to the development of C difficile diarrhea. Use of gastrointestinal drugs (ranitidine, famotidine, cimetidine, omeprazole and sucralfate) was also an added risk (aor=3.20, ci 1.39 to 7.34, P=0.01); however, antineoplastic therapy was not significant (P<0.53). Recognition of the specific high risk drugs may spur more restricted use of these agents, which may help in controlling C difficile diarrhea in hospitalized patients.

Demographic and physiological data for Chinese, along with information on CYP abundances and the frequencies of associated genetic polymorphisms in Chinese, were collated from literature sources and incorporated within the Simcyp Population-based Simulator(®) (v11.1). Default Simcyp parameter values for a virtual Caucasian population and for model compounds metabolized principally by specific CYPs were used as the point of reference. The drugs and the main CYPs involved in their metabolism were phenacetin (CYP1A2), desipramine (CYP2D6), tolbutamide (CYP2C9), omeprazole (CYP2C19), and alprazolam and midazolam (CYP3A). Hydroxy bupropion formation was used as a more sensitive marker of CYP2B6 activity than bupropion kinetics. Observed plasma drug concentration-time profiles and pharmacokinetic parameters after oral and, where possible, intravenous dosing were obtained from published in vivo studies in both Chinese and Caucasian subjects. Virtual subjects generated within Simcyp were matched to the subjects used in the in vivo studies with respect to age, sex, dosage and, where possible, CYP phenotype frequency. Predicted and observed plasma drug concentrations and weight-normalized clearances were compared between the ethnic groups.

For the 5-year period studied, LNF was less expensive than omeprazole (3519.89 dollars vs. 5464.87 dollars per patient) and became the more cost-effective option at 3.3 years of follow-up. The authors found that 20 mg/day omeprazole would have to cost less than 38.60 dollars per month before medical therapy became cost effective; conversely, the cost of LNF would have to be more than 5,273.70 dollars or the length of stay more than 4.2 days for medical therapy to be cost effective. Estimates of quality-adjusted life-years did not differ significantly between the two treatment options, and the incremental cost for medical therapy was 129,665 dollars per quality-adjusted life-years gained.
Mutations in the gene encoding the CYP2C-19 enzyme for PPI metabolism have been shown to enhance the chance for a cure in a H. pylori-positive patients using a two-week dual-therapy regimen involving omeprazole and amoxicillin. However, the impact of CYP2C-19 genetic polymorphism on eradication rates of a one-week triple-therapy regimen has not been examined. In this cohort study, 156 H. pylori-positive peptic ulcer or NUD patients who presented to our university hospital were recruited. They were treated by one-week omeprazole-amoxicillin-clarithromycin therapy. Host and bacterial predictive factors including H. pylori susceptibility and CYP2C-19 genotyping, as well as cure rate for H. pylori infection, were studied. Cure rate was 85.9% (95% CI: 79-91%) on an intent to treat (ITT) basis. By multiple logistic regression analysis, only clarithromycin resistance had a significant impact on treatment success (odds ratio 28.7: 95% CI: 6-172). CYP2C-19 genetic polymorphism was not associated with a significant change in cure rate. These observations indicate only clarithromycin susceptibility, not CYP2C-19 polymorphism, has a major impact on the treatment success when using a seven-day OAC H. pylori treatment regimen.

1. The potency and selectivity of omeprazole as an inhibitor of cytochrome P450-mediated drug oxidations has been assessed in hepatic microsomes from the untreated, phenobarbitone-treated, beta-naphthoflavone-treated and dexamethasone-treated rat. Using the marker substrates diazepam, ethoxycoumarin, ethoxyresofurin and ethylmorphine in the above microsomal preparations, inhibitory activity against CYP1A, 2B, 2C and 3A members of the cytochrome P450 superfamily were determined. 2. In each situation studied the kinetics of inhibition by omeprazole were competitive in nature with Ki's ranging from 25 to > 1000 microM. Marker activities for the 3A family in microsomes from the dexamethasone-treated and phenobarbitone-treated rat (3-hydroxylation of diazepam and N-demethylation of ethylmorphine) were most susceptible to omeprazole inhibition (Km/Ki ratios greater than unity) compared with marker activities for the CYP1A, 2B and 2C sub-families (Km/Ki ratios < or = unity). 3. Omeprazole sulphoxide showed similar potency and selectivity of inhibition to its parent drug. Analogous studies with the same marker activities using ketoconazole indicated that both omeprazole and its sulphoxide metabolite are less potent as an inhibitor of cytochrome P4503A in rat than this well characterised prototype.
