Review: Prevalence and dynamics of Helicobacter pylori infection during childhood
ConclusionsThe prevalence of H. pylori infection varied widely in the studies included here; nevertheless, model estimates by detection type were similar, suggesting that overall, one‐third of children worldwide are or have been infected. The few cohort and longitudinal studies available show variability, but most studies, show infection rates over 30%. Rather surprisingly, overall infection prevalence in symptomatic children was only slightly higher, around 40%. Studies including only one positive stool sample should be interpreted with caution as spontaneous clearance can occur. (Source: Helicobacter)

Antibacterial resistance and the success of tailored triple therapy in Helicobacter pylori strains isolated from Slovenian children
ConclusionsThe primary resistance rates of H. pylori to CLA and MET in Slovenia are high. Our data strongly support the fact that in countries with high prevalence of resistant H. pylori strains susceptibility testing and tailored therapy is essential. (Source: Helicobacter)

Detection of gastric atrophy by circulating pepsinogens: A comparison of three assays
ConclusionsCommercial assays for pepsinogen have good relative agreement but are imperfect tests for clinical diagnosis of gastric atrophy.
ImpactPepsinogen testing alone does not provide sufficient information for gastric cancer risk stratification. Future investigations should focus on other potential markers, in combination with pepsinogens. (Source: Helicobacter)

Usefulness of detection of clarithromycin ‐resistant Helicobacter pylori from fecal specimens for young adults treated with eradication therapy
ConclusionPCR‐based sequencing to detect CAM resistance‐associated mutations using isolates or fecal samples was useful for finding antibiotic‐resistant H. pylori infection. Although the specificity of the detection from fecal samples compared with antibiotic susceptibility testing was lower than that from isolates, this fecal detection method is suitable especially for asymptomatic subjects including children. Further improvement is needed before clinical application. (Source: Helicobacter)

Randomized controlled study of a novel triple nitazoxanide (NTZ) ‐containing therapeutic regimen versus the traditional regimen for eradication of Helicobacter pylori infection
ConclusionNitazoxanide‐containing triple therapy is a promising therapy for the first‐line eradication of H. pylori. (ClinicalTrials.gov Identifier: NCT02422706). (Source: Helicobacter)

Reduced infectivity of waterborne viable but nonculturable Helicobacter pylori strain SS1 in mice
ConclusionsWhile other studies that have used viable, culturable SS1 via gavage or drinking water exposures to successfully infect mice, in our study, waterborne VBNC SS1 failed to colonize mice under all test conditions. Future studies could examine different H. pylori strains in similar exposure scenarios to compare the relative infectivity of the VBNC vs the viable, culturable state, which would help inform future risk assessments of H. pylori in water.

Sensitivity of Helicobacter pylori detection by Giemsa staining is poor in comparison with immunohistochemistry and fluorescent in situ hybridization and strongly depends on inflammatory activity
ConclusionsWe highly recommend immunohistochemistry for clinically susceptible, nonactive chronic gastritis cases, if the conventional stain‐based HP detection is negative. Moreover, we recommend to use IHC more widely as basic HP stain. Helicobacter pylori FISH technique is primarily recommended to determine bacterial clarithromycin resistance. Furthermore, it is another accurate diagnostic tool for HP. (Source: Helicobacter)
