Effectiveness of Helicobacter pylori eradication established on the basis of examination of antibiotic resistance of the bacteria

Introduction
The treatment of Helicobacter pylori (HP) tends to be empirical despite a high number of failures (over 20%). The efficacy of eradication therapies is declining, reaching in some countries 60%, which correlates inversely with the growing drug resistance of the bacteria.

Aim
Given the frequent inefficacy of the hitherto proposed treatment schemes for HP infection, an attempt was made to assess the efficacy of a therapy based on the antibiotic resistance of the cultured bacteria, and to analyse factors with possible contribution to the inefficacy of HP eradication treatment.

Material and methods
The study covered patients from one region of Central Poland in the years 2005–2015. The total material for bacteriological assessment was collected from 154 patients who had previously been subject to HP eradication treatment at least two times, including 80 women and 74 men, reporting subsequently to the Clinic.

Results
The efficacy of the antibiogram-based treatment was merely 65.62%. A low, but slightly higher than expected, resistance to amoxicillin (3.48%) and tetracycline (2.27%), as well as to clarithromycin (27.27%) and metronidazole (70.69%), was established.

Conclusions
In Polish patients resistance to clarithromycin and metronidazole of HP is high and becoming increasingly resistant; however, we found low bacterial resistance to tetracycline.
