Evaluation of the Effectiveness of Eradication Regimens in Lithuania during the Years 2013-2020: Data from the European Registry on Management (Hp-EuReg).

: The prevalence of in Eastern Europe remains quite high; however, there is insufficient data on the eradication regimens and their effectiveness. Therefore, the objective of the study was to evaluate the diagnostic methods and treatment of infection as well as their adherence to Maastricht V/Florence consensus during the years 2013-2020 in Lithuania. : Sub-study of the "European Registry on Management" (Hp-EuReg), international multicenter prospective non-interventional registry of the routine clinical practice. Lithuanian data from the years 2013-2020 were analyzed for effectiveness on a modified intention-to-treat (mITT) basis. 2000 adult patients, diagnosed with infection, were included. Data were compared to the European Maastricht V guidelines. : Triple-therapy was used in 90% of the cases. In 91% of the first-line prescriptions, standard triple therapy (STT) was used. The most common second-line treatment was a combination of PPI, amoxicillin and levofloxacin (PPI+A+L) (47%). The overall effectiveness in 552 cases valid for analysis was 90% by mITT. In first-line treatment, the STT effectiveness was 90% and second-line treatment with PPI+A+L achieved 92% by mITT. Increasing overall eradication rates were observed: from 72% in 2013 to more than 90% in 2018-2020, as well as a shift from 7 to 10-14 days treatments duration throughout 2013-2020. : In Lithuania, the prescribed eradication regimens for were in accordance with the international guidelines but diagnostic methods and treatment duration only partially met Maastricht V/Florence guidelines. The eradication effectiveness was improved progressively during the years 2018-2020, reaching ≥90% cure rates.
