Advances in the pharmacotherapeutic management of refractory peptic ulcers.

INTRODUCTION

Refractory peptic ulcer is now a rare disease since most peptic ulcers heal with appropriate treatment with proton pump inhibitors (PPIs) and/or Helicobacter pylori eradication.

AREAS COVERED

The most frequent cause of apparent refractoriness is lack of adherence to treatment. Persistence of H. pylori infection, use or abuse (often surreptitious) of high dose non-steroidal anti-inflammatory drugs (NSAIDs) or aspirin (ASA) are the two major causes of true refractory ulcers. There is a growing number of peptic ulcers which are not linked to either NSAIDs or H. pylori infection. Refractoriness in these ulcers can be linked to gastric acid hypersecretion, rapid PPI metabolization, ischemia, chemo-radiotherapy, immune diseases, more rarely to other drugs or be fully idiopathic. Treatment of the cause of the ulcer, if known, is essential. This review is based on pertinent publications retrieved by a selective search in PubMed, with particular attention to refractory peptic ulcer.

EXPERT OPINION

High-dose PPI or the new potassium competitive acid blocker or the combination of PPIs with misoprostol can be recommended in these cases. Other more experimental treatments such the topical application of platelet-rich plasma or mesenchymal stem cells have also been suggested. Surgery is the last option, but there is no guarantee of success, especially in NSAID or ASA abusers.
