Treatment options for H.pylori infection in patients with penicillin allergy include first-line Bismuth-based quadruple therapy for 10-14 days, and second-line Levoflaxacin-based triple therapy for 10 days. Patients with persistent infection after 2 treatment courses should be tested for penicillin allergy, and treatment should be guided by H.pylori culture and sensitivity testing results.
Therapy of Helicobacter pylori (H.pylori) requires a combination of antibiotics together with an acid suppressing agent; most treatment regimens include Amoxicillin as one of the antibiotics, which is an important constituent as resistance to it is low. However, allergies to the penicillin group of antibiotics are not uncommon, and treating H.pylori infection in such individuals can be challenging due to the restricted choice of regimens. The aim of this review is to summarise the evidence for therapeutic options in patients with H.pylori infection and penicillin allergy. A literature search was conducted in PubMed for English language publications using the key words 'Helicobacter' and 'treatment' or 'therapy' and 'penicillin' or 'beta-lactam' and 'allergy' or 'anaphylaxis'. Eighteen studies were identified that specifically evaluated H.pylori treatment success in penicillin allergic patients. The number of subjects in most of them was low and many were retrospective, uncontrolled, single cohort studies. The most effective option for first-line treatment appears to be Bismuth-based quadruple therapy for 10-14 d. The evidence supports second-line treatment with Levoflaxacin-based triple therapy for 10 d. Patients with persistent H.pylori infection after 2 treatment courses should be considered for testing to confirm penicillin allergy. Further treatment should be guided by the results of H.pylori culture and sensitivity testing.
