The eradication of Helicobacter pylori reduces the risk of gastric cancer. A clear understanding of the factors underlying mixed infection with multiple clarithromycin-susceptible and clarithromycin-resistant H. pylori strains is necessary to design more effective therapies against H. pylori. We aimed to assess how the abundance and prevalence of H. pylori strains vary after clarithromycin-based eradication therapy. Using gastric wash samples, which represent the entire stomach, we sequentially analyzed the abundance and prevalence of H...

The application of coordination chemistry in the light of nanotechnology is a rapidly developing research field in medicine. Bismuth complexes have been widely and willingly used in biomedicine with satisfactory therapeutic effects, mostly in Helicobacter pylori eradication, but also as potential anti-microbial and anti-leishmanial agents. Additionally, in recent years, an application of bismuth-based compounds as potent anticancer drugs has also been studied extensively. Therefore, in this review, we want to highlight a number current problems connected with: (1) characterization of bismuth complexes based on thiosemicarbazone, hydrazone, and dithiocarbamate classes of ligands as potential chemotherapeutics, (2) pioneering research on application of bismuth-based nanoparticles and nanodots for radiosensitization, and (3) research challenges in using bismuth radionuclides in targeted radioimmunotherapy...

COMMENT

Attaran et al([1]) have recently shown that decreased susceptibility of established Helicobacter pylori (H. pylori) biofilms to specific antibiotics, was associated with the overtly enhanced transcription of two efflux pump genes, hp1165 and hefA, involved in specific resistance to tetracycline and multiple antibiotics, respectively. Apart from antibiotic exposure, secretion of multiple antimicrobial peptides, such as human β-defensins (hβDs), by the gastric epithelium upon Hp challenge, may act as early triggering events that positively impact biofilm formation and thus, antibiotic resistance...

Nitric oxide (NO) plays a key role in the development of peptic ulcer disease (PUD). Conversely, the gastric pathogen Helicobacter pylori colonizes the human stomach and contributes to the development of non-ulcer dyspepsia (NUD) and PUD. But, the underlying relation between molecular NO in exhaled breath and H. pylori associated NUD and PUD largely remains unknown. Here, we explored that the excretion kinetics of NO profiles in exhaled breath are markedly altered for H. pylori infected NUD and PUD subjects...
