Recent clinical guidelines have expanded not only the pool of patients who should be tested for Helicobacter pylori infection, but also the number of first-line treatment strategies clinicians should consider.
The American College of Gastroenterology guidelines from 2007 recommended just two treatments: clarithromycin-based triple therapy or bismuth-based quadruple therapy.
The 2017 update to ACG guidelines adds five additional recommended treatment possibilities, not all of which have been well studied in U.S. clinical practice, Colin W. Howden, MD, AGAF, said in a presentation at the inaugural Perspectives in Digestive Diseases meeting held by Global Academy for Medical Education.
“There are a variety of options, and unfortunately for us as practitioners, antibiotic sensitivity testing is not routinely or easily available in contemporary U.S. practice,” said Dr. Howden, professor of medicine–gastroenterology at the University of Tennessee Health Sciences Center, Memphis.
Dr. Howden, a coauthor of the latest ACG guidelines, said asking two pointed questions outlined in the document can help simplify the treatment decision:
- Is there a penicillin allergy?
- Has there been previous macrolide exposure?
“The ideal situation is that the patient is not penicillin allergic, and they’ve never had a macrolide before,” Dr. Howden said. In that case, bismuth-based quadruple therapy would be an appropriate choice.
