Aim: First, to assess the clarithromycin resistance (ClaR) rate 1) in patients with persistent
Helicobacter pylori (H. pylori) infection after eradication, 2) in patients with untreated …

Primary clarithromycin resistance is the main factor affecting the efficacy of Helicobacter
pylori therapy. This study aimed:(i) to assess the concordance between phenotypic (culture) …

Background. Primary clarithromycin resistance markedly reduces Helicobacter pylori
eradication rate following standard therapies. Prevalence of primary clarithromycin …

Objectives The frequency of primary clarithromycin resistance in Helicobacter pylori strains
is increasing worldwide, and its presence significantly reduces the treatment efficacy of …

Background: Growing resistance to clarithromycin is a major concern regarding treating
Helicobacter pylori (H. pylori) infection. Resistance rates have a great variation even in …

OBJECTIVES: We previously showed that real-time PCR was a reliable technique for
coupled detection of Helicobacter pylori and clarithromycin resistance mutations directly …

Background Helicobacter pylori clarithromycin resistance is increasing worldwide and
different mutations are involved in its mechanisms. Recently, molecular methods have been …

Helicobacter pylori infection can be eradicated in up to 90% of patients using current
combination of triple therapies, of which clarithromycin is a key component. The …

Conventional triple therapies for Helicobacter pylori (H. pylori) eradication have recently
shown a disappointing reduction in effectiveness in many countries. The main reason for …

A large survey of antimicrobial resistance of Helicobacter pylori was performed in France in
2014: 984 patients were enrolled by 75 gastroenterologists all over the country. Among the …
