Zusammenfassung
Aims: PPI are metabolised by the polymorphic CYP2C19. H.pylori eradication results according to different PPIs and dosages are inconsistent. Data from asian studies suggested that poor metabolisers of PPIs do better, data in caucasians are scarce. Objective/Methods: Meta-analysis of available literature data. Results: By mid of 2003, 12 studies met the inclusion criteria and reported differences in eradication outcome between wt/wt (wildtype, extensive metabolisers) vs. combined wt/mt and mt/mt (mutant, deficient metabolisers) alleles. Significant (p=0.0012) heterogeneity could be observed and was resolved (p=0.…
