ABSTRACT
OBJECTIVES:
This study was carried out to screen the use of Helicobacter pylori stool antigen (HpSA) tests for diagnosis and monitoring of H pylori in Nigeria.METHODS:
Seven hundred and forty participants were enrolled after informed consent was obtained, while 83 came back for a post-eradication test. The stool samples were taken from the patients at endoscopy and tested for HpSA.RESULTS:
The proportion of patients that were positive at the pretest, 520 (70.3%) was significantly higher (Fisher's exact p = 0.001) than those positive at the post-test, 44 (53%). There was a significant difference (F = 4.106, p = 0.043) between the mean age of those that came for the pretest (40.0 ± 14.5 years) and those that came for the post-test, 43.6 ± 11.6 years. More males than females had the tendency to come back for a post-eradication test.CONCLUSION:
Although potential bias was introduced during this study, HpSA using monoclonal antibody could still be used for diagnosis and monitoring of H pylori in Nigeria.RESUMEN
OBJETIVOS:
Este estudio se llevó a cabo con el propósito de examinar el uso del test de antígeno en heces (HpSA) para el diagnóstico y monitoreo de Helicobacter pylori en NigeriaMÉTODO:
Tras obtener su consentimiento informado, se enrolaron ciento cuarenta participantes, mientras que 83 regresaron para un test de post-erradicación. Las muestras de heces fueron tomadas de pacientes en endoscopia e investigadas en busca de HpSA.RESULTADOS:
La proporción de pacientes que resultaron positivos en el test previo, 520 (70.3%) fue significativamente mayor (Test exacto de Fisher p = 0.001) que la de los que resultaron positivos en el test posterior, 44(53%). Hubo una diferencia significativa (F = 4.106, p = 0.043) entre la edad promedio de los que vinieron al test previo (40.0 ± 14.5 años) y la de aquellos que vinieron al test posterior, 43.6 ± 11.6 años. Más varones que hembras mostraron tendencia a regresar al test de post-erradicación.CONCLUSION:
Aunque un sesgo potencial fue introducido en este estudio, HpSA con anticuerpos monoclonales podría todavía usarse para el diagnóstico y monitoreo de H pylori en Nigeria.Key words
