ABSTRACT

PURPOSE: Many of the currently used eradication regimens against Helicobacter pylori fail to cure the infection either due to antimicrobial resistance or to poor patient compliance. The infection leads to increased risk of developing potentially severe complications, such as gastric cancer. This study was aimed at assessing the efficacy and safety of a quadruple therapy with furazolidone for H. pylori retreatment. METHODS: Patients who had failed one or more eradication regimens against H. pylori infection underwent upper gastrointestinal endoscopy. Biopsy specimens were taken from the gastric antrum and corpus for histology and for a urease test and. Patients received omeprazole 20 mg, bismuth citrate 240 mg, tetracycline 500 mg, and furazolidone 200 mg, all twice daily for 7 days. Therapeutic success was evaluated by endoscopy and biopsies 8 weeks after the end of treatment. RESULTS: Sixty two patients were enrolled, and 58 completed the study. Under this protocol, H. pylori eradication was achieved in 39/58 patients (67%). Mild adverse events were reported. CONCLUSION: The short quadruple therapy course with furazolidone is well tolerated, inexpensive, and effective in retreatment for H. pylori infection. It is a good option for developing countries.

ABSTRACT

OBJETIVO: Muitos dos esquemas atualmente usados na erradicação do Helicobacter pylori não conseguem curar a infecção, pela resistência bacteriana ou pela baixa adesão do paciente. Esta condição manterá os riscos de desenvolvimento das potenciais complicações graves da infecção. Este estudo procurou determinar a eficácia e segurança de um esquema quádruplo que associou a furazolidona para o retratamento da infecção pelo H. pylori. MÉTODOS: Pacientes que não alcançaram erradicação em um ou mais tratamentos foram submetidos à endoscopia digestiva alta e dois fragmentos do antro e do corpo foram retirados para exame histológico e de urease. Receberam então 20mg de omeprazol, 240mg de sub-citrato de bismuto, 500mg de tetraciclina e 200mg de furazolidona duas vezes ao dia por 7 dias. O sucesso terapêutico foi determinado pela negativação de nova biópsia endoscópica, após 8 semanas do tratamento. RESULTADOS: Sessenta e dois pacientes foram incluídos, cinqüenta e oito completaram o estudo. Por protocolo, 67% (39/58) dos pacientes conseguiram a erradicação da bactéria. Efeitos adversos leves foram relatados. CONCLUSÃO: O tratamento de curto prazo, em esquema quádruplo com a furazolidona , é bem tolerado, barato e eficaz no re-tratamento do H. pylori. Uma boa opção de re-tratamento para países em desenvolvimento.
