Helicobacter pylori resistance to clarithromycin in Reunion Island

Médecine et Maladies Infectieuses, 2016
The increasing resistance of Helicobacter pylori to clarithromycin led to developing new eradication treatment regimens. The objective of our observational study was to determine the proportion of H. pylori strains resistant to clarithromycin in infected patients in Reunion Island and to suggest a first-line treatment in agreement with the local ...

Helicobacter pylori resistance to metronidazole and clarithromycin in Ireland

European Journal of Gastroenterology & Hepatology, 2010
Helicobacter pylori eradication rates have fallen considerably in recent years. Antibiotic resistance is thought to be rising.To examine the levels of resistance to metronidazole (MTZ) and clarithromycin (CLA) in H. pylori, isolates were taken in a reference centre in Ireland from 2007 to 2008 and were compared to a similar cohort from a study in 1997 ...

Clarithromycin-Resistant Genotypes and Eradication of Helicobacter pylori

Annals of Internal Medicine, 2006
Three point mutations (A2143G, A2142G, and A2142C) have been involved in Helicobacter pylori clarithromycin resistance.To compare the eradication rates among the different point mutations and the efficacy of triple therapy and a sequential regimen according to genotypic resistance.Post hoc subgroup study from a multicenter, randomized trial.Two ...

High Helicobacter pylori Resistance Rate to Clarithromycin in Turkey

Journal of Clinical Gastroenterology, 2007
To assess the resistance of Helicobacter pylori to clarithromycin in Turkey.Recent studies have emphasized the remarkable reduction in H. pylori eradication rates. Resistance to clarithromycin is the most important factor affecting the success of H. pylori eradication therapies.The study involved 110 consecutive adult dyspeptic patients infected with H.

Clarithromycin resistance of Helicobacter pylori has a major impact on the efficacy of the omeprazole-amoxicillin-clarithromycin therapy

Pathologie Et Biologie, 2001
Clarithromycin resistance of Helicobacter pylori is relatively frequent in France and is assumed to be the main cause of failure of the proton pump inhibitor-amoxicillin-clarithromycin (PPI-AC) therapy, which is the first-line regimen in our country. We determined the respective effects of clarithromycin primary and secondary resistances on efficacy of

The Helicobacter pylori Resistance Rate to Clarithromycin in Iran

Microbial Drug Resistance, 2014
Background: Clarithromycin is the most commonly suggested antibiotic in Helicobacter pylori eradication regimens. Increasing antibiotic resistance rate to clarithromycin is the main reason for therapeutic failure.

Prevalences of metronidazole‐ and clarithromycin‐resistant Helicobacter pylori isolates in Shanghai and molecular mechanism of resistance to clarithromycin

Chinese Journal of Digestive Diseases, 2001
OBJECTIVE: To investigate the prevalences of metronidazole‐ and clarithromycin‐resistant Helicobacter pylori over the period from 1995 to 1999 in Shanghai, and the molecular mechanism of resistance to clarithromycin. METHODS: A total of 150 H. pylori strains were randomly selected from the isolates collected in 1995, 1997 and 1999, and tested for ...

[Genotypic homogeneity and susceptibility to clarithromycin for clarithromycin-resistant Helicobacter pylori strains].

Zhonghua yi xue za zhi, 2010
To investigate the mixed infection of clarithromycin susceptibility and genotype of Helicobacter pylori resistant strains.Ten single colonies were picked randomly from each of 16 resistant strains. Genomic DNA was prepared from single colony isolates and their parental clarithromycin-resistant strains by the hexadecyltrimethylammonium bromide (CTAB ...
