摘要: Abstract Objectives Clarithromycin resistance (CLR-R) is the main reason for failure of Helicobacter pylori infection treatment, which frequently empirically prescribed due to erroneous belief that culture susceptibility testing difficult. The aim this study was determine CLR-R in a region southern Europe and evaluate utility PCR sequencing assay applied on gastroduodenal biopsies detecting H. clarithromycin (CLR) susceptibility. Methods all isolates obtained by during 2013–2015 determined Etest. During 2014–2015, detection CLR were also studied followed performed biopsies. Point mutations 23S rRNA gene CLR-resistant 2014. Results Of 1986 (63 from children 1923 adults), 349 (17.6%) [21/63 (33.3%) 328/1923 (17.1%) adults; P 0.001], 31.5% resistant levofloxacin. detected A2147G (79.8%), A2146G (17.2%) A2146C (2%). Concordance between Etest after 89.8%. Conclusions high Gipuzkoa, northern Spain. molecular method directly good alternative traditional an aid when non-viable.
