El efecto del consumo de café en el desarrollo de carcinoma hepatocelular en zona endémica del virus de la hepatitis B
27-04-2017
Un estudio de casos y controles se adelantó con el objetivo de explorar la relación entre consumo de café durante toda la vida y el riesgo de desarrollo de carcinoma hepatocelular (CHC) considerando el estatus de replicación del virus de la hepatitis B (VHB), en una región endémica. Se incluyeron 1364 sujetos de los cuales 258 presentaron CHC (casos), 480 pacientes sanos (controles 1) y 626 pacientes con enfermedad hepática crónica diferente a CHC (controles 2). Se aplicó un instrumento estandarizado que exploró variables como el hábito de fumar, beber alcohol y consumo de café. También se adelantó una medición de niveles de antígeno-e del VHB (HBeAg) y ADN del VHB en el suero de pacientes infectados por el VHB. Se aplicó un modelo de regresión logística multivariable ajustada por edad, género, obesidad, antecedente de Diabetes Mellitus, tabaquismo, consumo de alcohol y consumo de café. Para el caso de los controles 2, la etiología viral de la enfermedad hepática crónica también fue incluida como covariable. Después de ajustar por estas variables se evidenció que un alto consumo de café durante toda la vida (>= 20 000 tazas) resultó asociado inversamente con CHC. Lo anterior aplicó para cada análisis utilizando grupos de control sanos y a riesgo respectivamente (el grupo sano, OR 0.56, IC 95% 0.33-0.95; grupo enfermedad hepática crónica OR 0.55, CI 95% 0.36-0.85). Sin embargo, el alto consumo de café no afectó el riesgo de CHC en pacientes con VHB (OR 0.64, CI 95% 0.36-1.14) después de ajustar por el estado de HBeAg, el nivel de ADN de HBV en suero y la terapia antiviral. En conclusión, en este estudio se evidenció que un alto consumo de café en toda la vida está inversamente asociado al desarrollo de CHC.
