Helicobacter pylori Eradication with Either Seven-Day or 10-Day Triple Therapies, and with a 10-Day Sequential Regimen

BACKGROUND Helicobacter pylori eradication rates achieved by standard seven-day triple therapies are decreasing in several countries, while a novel 10-day sequential regimen has achieved a very high success rate. A longer 10-day triple therapy, similar to the sequential regimen, was tested to see whether it could achieve a better infection cure rate. METHODS Patients with nonulcer dyspepsia and H pylori infection were randomly assigned to one of the following three therapies: esomeprazole 20 mg, clarithromycin 500 mg and amoxycillin 1 g for seven days or 10 days, or a 10-day sequential regimen including esomeprazole 20 mg plus amoxycillin 1 g for five days and esomeprazole 20 mg, clarithromycin 500 mg and tinidazole 500 mg for the remaining five days. All drugs were given twice daily. H pylori eradication was checked four to six weeks after treatment by using a 13C-urea breath test. RESULTS Overall, 213 patients were enrolled. H pylori eradication was achieved in 75.7% and 77.9%, in 81.7% and 84.1%, and in 94.4% and 97.1% of patients following seven-day or 10-day triple therapy and the 10-day sequential regimen, at intention-to-treat and per protocol analyses, respectively. The eradication rate following the sequential regimen was higher than either seven-day (P=0.002) or 10-day triple therapy (P=0.02), while no significant difference emerged between the latter two regimens (P=0.6). CONCLUSIONS The 10-day sequential regimen was significantly more effective than both triple regimens, while 10-day triple therapy failed to significantly increase the H pylori eradication rate achieved by the standard seven-day regimen.

Concomitant, sequential, and hybrid therapy for H. pylori eradication: A pilot study

BACKGROUND AND OBJECTIVE Since the efficacy of the standard triple therapies for Helicobacter pylori eradication has decreased, novel antibiotic regimens have been introduced, including concomitant, sequential, and hybrid therapies. We aimed to compare the cure rates achieved by these new therapy regimens. METHODS This was a multicenter, open-label, pilot study enrolling consecutive non-ulcer dyspepsia patients with H. pylori infection never previously treated for the infection. Patients were randomized to receive one of the following treatments: (a) concomitant therapy: omeprazole 20mg, amoxicillin 1g, clarithromycin 500 mg, and tinidazole 500 mg for 5 days; (b) sequential therapy: omeprazole 20mg and amoxicillin 1g for 5 days followed by omeprazole 20mg, clarithromycin 500 mg, and tinidazole 500 mg for 5 days; (c) hybrid therapy: omeprazole 20mg, and amoxicillin 1g for 7 days followed by omeprazole 20mg, amoxicillin 1g, clarithromycin 500 mg, and tinidazole 500 mg, for 7 days. All drugs were administered twice daily. Bacterial eradication was checked 6 weeks after treatment by using a (13)C-urea breath test. A 10-day, second-line therapy with omeprazole 20mg, levofloxacin 250 mg, and amoxicillin 1g, all given twice daily, was offered to the eradication failure patients. RESULTS Overall, 270 patients were enrolled, but 13 patients early interrupted treatment due to side effects. At intention-to-treat (ITT) and per-protocol analysis (PP), the eradication rates were 85.5% and 91.6% with the concomitant regimen, 91.1% and 92.1% with the sequential therapy, and 80% and 85.7% with the hybrid regimen. Differences were not statistically significant. H. pylori infection was cured in 10 (55.6%) patients with the second-line regimen. CONCLUSION In our study, both concomitant and sequential therapy, but not hybrid therapy, reached high eradication rates. The success rate of second-line levofloxacin-based triple therapy is decreasing.

Sequential treatment for Helicobacter pylori eradication in duodenal ulcer patients: improving the cost of pharmacotherapy

Background : Several studies have shown that Helicobacter pylori eradication rates with standard 7‐day triple therapy are unsatisfactory. A novel 10‐day sequential treatment regimen recently achieved a significantly higher eradication rate. To improve the pharmacotherapeutic cost, we evaluated whether an acceptable eradication rate could be achieved in peptic ulcer patients by halving the dose of clarithromycin.

Novel Therapeutics for the Treatment of Familial Mediterranean Fever: From Colchicine to Biologics

Familial Mediterranean fever (FMF), an inherited autosomal recessive disorder, is characterized by sporadic, paroxysmal attacks of fever and serosal inflammation, lasting 1–3 days. Patients may develop renal amyloidosis, arthritis, serositis, and skin and oral lesions. Diagnosis is based on clinical features, response to treatment with colchicine, and genetic analysis. Colchicine prevents attacks and renal amyloidosis, in addition to reversing proteinuria. Nonresponders may receive novel therapy, including interleukin (IL)‐1 receptor antagonists and IL‐1 decoy receptor. Recently, new options have been considered.

Lactobacillus reuteri strain combination in Helicobacter pylori infection: a randomized, double-blind, placebo-controlled study.

Goals: The goals of this study were to investigate the role of a new probiotic preparation (Lactobacillus reuteri DSM 17938 and L. reuteri ATCC PTA 6475) in Helicobacter pylori infection. Background: Specific probiotic strains play a role in H. pylori infection for their ability to decrease bacterial load and gastritis, prevent antibiotic-associated side effects, and increase the eradication rate. Study: This is a prospective, double-blind, randomized, placebo-controlled study in a tertiary care setting. A total of 100 H. pylori–positive naive patients received either L. reuteri combination (2×108 Colony Forming Units) or placebo during a 3-phase study (pre-eradication, eradication, and follow-up). All underwent 13C urea breath test (13C-UBT), blood assessments of gastrin-17 (G17), endoscopy, and the Gastrointestinal Symptom Rating Scale. Eradication was confirmed by 13C-UBT 8 weeks after the completion of therapy. Results: Fifty patients were allocated in each group. During pre-eradication period, 13C-UBT &dgr; decreased by 13% in L. reuteri combination as compared with a 4% increase in placebo (−13.2±34% vs. 4.3±27%; P<0.03). During eradication, GSRS increased significantly in placebo as compared with L. reuteri combination (6.8±2.9 vs. 4±3.1; P<0.01). Significantly less patients in L. reuteri combination as compared with placebo-reported side effects (40.9% vs. 62.8%; P<0.04). An abnormal G17 value was found in patients receiving placebo as compared with L. reuteri combination (28% vs. 12%; P<0.02). Eradication rate was 75% in L. reuteri combination and 65.9% in placebo (P=NS). L. reuteri combination increased eradication rate by 9.1% (odds ratio: 1.5). Conclusions: L. reuteri combination alone is able to exert an inhibitory effect on H. pylori growth, and when administered with eradication therapy, it determines a significant reduction in antibiotic-associated side effects. Moreover, L. reuteri combination was able to decrease serum G17 levels and to (not significantly) increase the H. pylori–eradication rate.

Familial mediterranean fever: a fascinating model of inherited autoinflammatory disorder.

Familial Mediterranean fever (FMF) is a rare inherited autosomal recessive autoinflammatory disorder characterized by recurrent and self‐limited episodes of fever and painful serositis, lasting 1–3 days. FMF occurs almost exclusively among ethnic groups of the Mediterranean basin, although cases have also been found in Japan and Korean populations. Diagnosis is based on clinical features, response to colchicine and genetic analysis. Novel drugs are emerging, allowing better management of colchicine‐resistant/colchicine‐intolerant patients. This review aims to attract the attention of the readers on differential diagnosis and management of patients with FMF.
