When 16S ribosomal RNA gene sequencing and other research showed in 1989 that the bacterium did not belong in the genus Campylobacter, it was placed in its own genus, Helicobacter from the ancient Greek έλιξ (hělix) "spiral" or "coil".In October 1987, a group of experts met in Copenhagen to found the European Helicobacter Study Group (EHSG), an international multidisciplinary research group and the only institution focused on H. pylori. The Group is involved with the Annual International Workshop on Helicobacter and Related Bacteria, the Maastricht Consensus Reports (European Consensus on the management of H. pylori), and other educational and research projects, including two international long-term projects:

European Registry on H. pylori Management (Hp-EuReg) – a database systematically registering the routine clinical practice of European gastroenterologists. Optimal H. pylori management in primary care (OptiCare) – a long-term educational project aiming to disseminate the evidence based recommendations of the Maastricht IV Consensus to primary care physicians in Europe, funded by an educational grant from United European Gastroenterology. Research
Results from in vitro studies suggest that fatty acids, mainly polyunsaturated fatty acids, have a bactericidal effect against H. pylori, but their in vivo effects have not been proven. See also

Estradiol valerate/dienogest (EV/DNG), sold under the brand names Lafamme, Natazia and Qlaira among others, is a combination product of estradiol valerate, an estrogen, and dienogest, a progestogen, which is used in menopausal hormone therapy in and as a birth control pill to prevent pregnancy in women. It is taken by mouth. Birth control pills containing EV/DNG are associated with a significantly increased risk of venous thromboembolism. However, they are associated with a significantly lower risk of venous thromboembolism than birth control pills containing ethinylestradiol and a progestin. See also
