Hv. Mao et al., Omeprazole or ranitidine bismuth citrate triple therapy to treat Helicobacter pylori infection: a randomized, controlled trial in Vietnamese patientswith duodenal ulcer, ALIM PHARM, 14(1), 2000, pp. 97-101
Aim: To evaluate the effectiveness of triple therapy containing either omep
razole or ranitidine bismuth citrate (RBC) to treat H. pylori infection in
Vietnamese duodenal ulcer patients.
Methods: Patients infected with H. pylori were randomized to receive either
omeprazole (20 mg b.d.), clarithromycin (500 mg b.d.) and amoxycillin (1 g
b.d.) for 10 days (OAC), or RBC (400 mg b.d.), clarithromycin (500 mg b.d.
) and amoxycillin (1 g b.d.) for 10 days (RAC). H. pylori eradication and u
lcer healing was established by a follow-up oesophagogastroduodenoscopy (EG
D) at least 4 weeks after therapy. Side-effects and compliance were assesse
d.
Results: One hundred and four out of 108 (96%) patients with a duodenal ulc
er were infected with H. pylori. Eighty per cent of infected patients had d
etectable CagA IgG antibodies. Fifty-seven patients received OAC and 47 rec
eived RAC. OAC eradicated H. pylori in 91 and 86% of patients by per protoc
ol (PP) and intention-to-treat (ITT) analysis, respectively. PP and ITT era
dication rates for RAC were 96 and 91%. Ulcer healing at the follow-up EGD
was 89% with OAC and 100% with RAC. Side-effects were minor. No patient fai
led to complete the protocol due to side-effects.
Conclusion: Triple therapy with either omeprazole or RBC is highly effectiv
e in eradicating H. pylori and healing duodenal ulcer in Vietnamese patient
