The Working Party Report on the Management of Helicobacter pylori serves as a clinical practice guideline for Malaysian doctors. H. pylori is not uncommon in the Malaysian population. Marked racial differences and the consistently low prevalence rates amongst Malays are noted. The working party recommends that if endoscopy is to be performed, a rapid urease test should be used for diagnosis. Where suspicion of the infection is strong and the urease test is negative, histology should be performed on gastric biopsies. Culture should be used to monitor resistance patterns to antibiotics and regional laboratories should assume this responsibility. The urea breath tests are highly accurate tests for diagnosis of H. pylori but is as yet not widely available in Malaysia. The working party strongly recommends that all peptic ulcer patients infected with H. pylori whether active, in remission and complicated ulcers should be treated for the infection. Patients with low-grade gastric mucosal lymphoid tissue lymphoma should also be treated for H. pylori infection. It is considered advisable that patients on long term nonsteroidal antinflammatory drug (NSAID) treatment with a history of peptic ulcers or dyspepsia and patients following resection of early gastric cancer or those with a family history of gastric cancer should also be tested and treated for H. pylori. The working party recommends, as first line treatment a 7-day combination therapy of a proton pump inhibitor, clarithromycin and metronidazole or amoxicillin. High metronidazole resistance rates locally may adversely affect regimens containing the antibiotic. It should also be noted that regimens that yield lower eradication rates may result in higher long term expenditure.
