ABSTRACT
BACKGROUND: Optimal anti-Helicobacter pylori treatment has not yet been established. AIM: To evaluate H. pylori eradication using tetracycline and furazolidone versus amoxicillin and azithromycin in lansoprazole based triple therapy in northeastern of Brazil. PATIENTS AND METHODS: One hundred and four patients with H. pylori infection, as determined by rapid urease testing and histology, were randomly assigned to receive either: lansoprazole (30 mg q.d.), tetracycline (500 mg q.i.d.), and furazolidone (200 mg t.i.d.) for 7 days (LTF; n = 52); or lansoprazole (30 mg b.i.d.) and amoxicillin (1 g b.i.d.) for 1 week, plus azithromycin (500 mg q.d.) for the first 3 days (LAAz; n = 52). H. pylori eradication was assessed 3 months following completion of therapy by means of rapid urease testing, histology and a 14C-urea breath test. RESULTS: H. pylori eradication was achieved in 46 of 52 (88.4%, 95% CI: 77.5%-95.1%) patients in LTF group and in 14 of 52 (26.9%, 95% CI: 16.2%-40,1%) patients in LAAz group. On a per-protocol analysis, eradication rates were 91.8% (95% CI: 81.4%-97.3%) and 28.5% (95% CI: 17.2%-42.3%), respectively in LTF and LAAz groups. CONCLUSION: The LAAz regimen yielded unacceptably low eradication rates. On the other hand, the LTF scheme represents a suitable alternative for H. pylori eradication.

RACIONAL: Ainda não está estabelecida a melhor terapêutica anti-H. pylori. OBJETIVO: Avaliar a erradicação de H.pylori usando tetraciclina e furazolidona versus amoxicilina e azitromicina em terapia tríplice com lansoprazol no nordeste do Brasil. PACIENTES E MÉTODOS: Cento e quatro pacientes infectados por H. pylori, diagnosticado através do teste rápido da urease e histologia, foram selecionados aleatoriamente para receber: lansoprazol (30 mg q.d.), tetraciclina (500 mg q.i.d.), furazolidona (200 mg t.i.d.) por 7 dias (LTF; n = 52); ou lansoprazol (30 mg b.i.d.) e amoxicilina (1 g b.i.d.) por 1 semana, mais azitromicina (500 mg q.d.) nos primeiros 3 dias (LAAz; n = 52). A erradicação de H.pylori foi avaliada 3 meses após término da terapia através do teste da urease, histologia e teste respiratório usando uréia marcada com 14Carbono. RESULTADOS: A erradicação do H. pylori foi atingida em 46 de 52 (88.4%, 95% CI: 77.5%-95.1%) pacientes no grupo LTF e em 14 de 52 (26.9%, 95% CI: 16.2%-40,1%) pacientes no grupo LAAz. Na análise per-protocolo, a taxa de erradicação foi de 91.8% (95% CI: 81.4%-97.3%) e 28.5% (95% CI: 17.2%-42.3%), respectivamente no grupo de LTF e LAAz. CONCLUSÃO: O esquema com LAAz ofereceu taxas de erradicação inaceitáveis. Por outro lado, o esquema com LTF representa alternativa adequada para erradicação de H.pylori.
