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 ...

Comparison of Clarithromycin-sensitive and Clarithromycin-resistant Mycobacterium avium Strains Isolated from AIDS Patients during Therapy Regimens including Clarithromycin

Journal of Infection, 2000
Sixteen Mycobacterium avium strains were isolated from the blood of eight AIDS patients over a period of months. All the patients were on combination therapies including clarithromycin, and all had treatment failure and relapses of M.avium bacteremia. Paired clarithromycin-sensitive and resistant M.avium strains isolated at the beginning of treatment ...

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.

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 ...

Genotypic characterization of clarithromycin-resistant Helicobacter pylori strains.

The new microbiologica, 2002
Helicobacterpylori (Hp) resistance to clarithromycin, one of the antibiotics most used to eradicate infection, is connected with the presence of a point mutation on the level of adenine at position 2143 or 2144 of 23S rRNA.The aim of the study is to evaluate of the presence of these mutation vs control clarithromycin resistant Hp strains present in ...

Metronidazole Resistance Reduces Efficacy of Triple Therapy and Leads to Secondary Clarithromycin Resistance

Digestive Diseases and Sciences, 1997
There has been a significant increase in the prevalence of H. pylori resistance to metronidazole in recent years, while clarithromycin resistance is still relatively rare. In this study we assessed: (1) the effect of primary H. pylori resistance to metronidazole and clarithromycin on the clinical efficacy of a one-week regimen consisting of omeprazole,

[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 ...

The Helicobacter pylori Resistance Rate to Clarithromycin in Iran

Microbial Drug Resistance, 2015
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.
