Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

Periodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

Periodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

Selection of Resistance to Clarithromycin in Mycobacterium abscessus Subspecies [PDF]

Antimicrobial Agents and Chemotherapy, 2017
ABSTRACT Mycobacterium abscessus is an emerging pathogen against which clarithromycin is the main drug used. Clinical failures are commonly observed and were first attributed to acquired mutations in rrl encoding 23S rRNA but were then attributed to the intrinsic production of the ...

Polymorphism of virulence genes and biofilm associated with in vitro induced resistance to clarithromycin in Helicobacter pylori

Gut Pathogens, 2023
Background Clarithromycin-containing triple therapy is commonly used to treat Helicobacter pylori infections. Clarithromycin resistance is the leading cause of H. pylori treatment failure. Understanding the specific mutations that occur in H.

A Mechanism of Clarithromycin Resistance in Helicobacter pylori

Journal of the Japanese Association for Infectious Diseases, 1998
The aim of this study was to elucidate the mechanism of clarithromycin (CAM) resistance in laboratory strains and clinical isolates of Helicobacter pylori. The CAM resistance in laboratory strains was induced in vitro by CAM exposure. The majority of CAM-resistant strains were highly resistant to CAM (MICs > 100 micrograms/ml).

Genotypic and Phenotypic Resistance to Clarithromycin in Helicobacter pylori Strains [PDF]

Journal of Clinical Medicine, 2020
Background: The increasing prevalence of antimicrobial resistance, together with the lack of novel treatment options, negatively affects successful eradication of Helicobacter pylori. The aim of this study was to investigate genetic mutations in the 23S rRNA genes, which is associated with clarithromycin resistance, and to determine the clinical impact

Detection of antimicrobial resistance genes of Helicobacter pylori strains to clarithromycin, metronidazole, amoxicillin and tetracycline among Egyptian patients

Egyptian Journal of Medical Human Genetics, 2018
Background: Antibiotic resistance of Helicobacter pylori (H. pylori) treatment is on the rise, and is affecting the efficacy of current used therapeutic regimens. Aim: We aimed to enhance the understanding of antimicrobial resistance rates of H.

Primary resistance to clarithromycin, metronidazole and amoxicillin of Helicobacter pylori isolated from Tunisian patients with peptic ulcers and gastritis: a prospective multicentre study

Annals of Clinical Microbiology and Antimicrobials, 2010
Background The frequency of primary resistance to antibiotics in H. pylori isolates is increasing worldwide. In Tunisia, there are limited data regarding the pattern of H. pylori antibiotic primary resistance. Aim To evaluate the primary resistance of H.
