Core Tip

Core tip: Clarithromycin resistance is the main reason for the failure of conventional therapies for Helicobacter pylori. We evaluate the scope of the problem, as reported in literature and especially on the basis of personal data in adult and paediatric populations. Another issue is the detection of resistance using phenotypic and genotypic methods; comparison is made of the limits and advantages of these approaches. Cost/benefit analysis of unsuccessful eradication therapy is performed. Based on these considerations, the best solution in future seems likely to be the detection of resistant strains before starting treatment.
