Abstract
Objetivo:
Erradicar H. pylori en pacientes dispepticos
de una población de alto riesgo de cancer
gástrico
Poblacion y metodos:
A 174 pacientes dispepticos, de una
poblacion de alto riesgo de cancer gastric°, se
les determinó la pre valencia de infección por H.
pylori y la tasa de erradicaciOn ocho semanas
despues de recibir: amoxicilina, subcitrato de
bismuto y metronidazol.
Resultados:
El 98% los pacientes estaban infectados. Se
erradica la bacteria solo en el 10.8% de los 83
pacientes que tomaron mas del 75% de los
medicamentos.
Conclusiones:
Las caracteristicas ecológicas y socio-economicas
de los pacf-s tropicales en desarrollo hacen que se
usen, mal usen y abuse de los antibiOticos, desde la
infancia, lo que posibilita la presencia de cepas
resistentes a los antibiaticos, especialmente al
metronidazol. Este hecho junto con la alta
probabilidad de infección y reinfeccion cuestiona
el empleo de tratamientos que no hayan sido
validados en esos paises. Los esfuerzos deberían
dirigirse a conocer el comportamiento de la bacteria
y su trasmisión con miras a prevenir la
infección y a la búsqueda de una vacuna.
Objetive: Elimination H. pylori in dyspeptic patients from a population at high-risk for gastric cancer. Population and methods: In 174 dyspeptic patients from a population at high-risk for gastric cancer, the prevalence rate of H. pylori infection and the perceilt erradication at 8 weeks after treatment with amoxicillin, bismuth subsalicylate and metronidazole were determined. Results: 98% of patients were infected. The bacteria was eliminated in only 10.8% of the 83 patients who took more than 75% of the medicines. Conclusions: Due to ecological and socioeconomical characteristics of tropical countries, frequent use and abuse of antibiotics exists from infancy and this facilitates the presence of strains which are ree)- tant to antibiotics, particularly metronidazole. A .is finding, together with the high probability of infection and reinfection, question the use of treatments that have not been validated in these countries. Efforts should be directed towards determinnig the behaviour of the bacteria and its transmission in order to prevent infection and search for an effective vaccine.
