Protocol of the European Registry on the management of Helicobacter pylori infection (Hp-EuReg).

INTRODUCTION

Helicobacter pylori selectively infects the human stomach, being the most prevalent chronic infection in the world. H pylori presence causes chronic gastritis in 100% of infected patients and is the major cause of relevant diseases such as atrophic gastritis, peptic ulcer disease, and gastric cancer; it is for this reason that from a public health standpoint, it is considered a high-impact pathogen, responsible of a significant morbidity and mortality. Nowadays, there are consensus and clinical guidelines regarding the infection management at a European level and in most of European countries, but no data have shown the level of implementation of these recommendations. The high costs that this infection carries both socially and to the health system require the continuous and systematic assessment of the diagnostic and treatment strategies, as well as the accessibility to diagnostic methods and most efficient drugs.

AIM: To register the diagnosis, management strategies, and treatment of H pylori-infected adult patients in the Digestive Services outpatient clinics throughout Europe.

METHODS

Noninterventionist prospective multicentre international Registry promoted by the European Helicobacter and Microbiota Study Group. National Coordinators will select recruiting gastroenterologists in their country that will register the H pylori-related routine clinical practice consultations they receive in an electronic case report form (e-CRF) provided by AEG-REDCap. Variables retrieved will include clinical, diagnostic, treatment, eradication confirmation, and outcome data. The database will allow researchers to perform specific subanalyses after approval by the Scientific Committee of the study.
