The frequency of primary clarithromycin resistance in Helicobacter pylori strains is increasing worldwide, and its presence significantly reduces the treatment efficacy of infection. This study aimed to evaluate whether the progression of the prevalence of clarithromycin resistance over a 15 year period has increased and whether a possible change in the distribution of the three most frequent point mutations, which account for the large majority of clarithromycin resistance cases, has taken place.

Abstract
The frequency of primary clarithromycin resistance in Helicobacter pylori strains is increasing worldwide, and its presence significantly reduces the treatment efficacy of infection. This study aimed to evaluate whether the progression of the prevalence of clarithromycin resistance over a 15 year period has increased and whether a possible change in the distribution of the three most frequent point mutations, which account for the large majority of clarithromycin resistance cases, has taken place.File in questo prodotto:
