Efecto de cisapride sobre el sobrecrecimiento bacteriano intestinal y la translocación bacteriana en la cirrosis

Abstract

La alteración de la motilidad intestinal que se detecta con frecuencia en la cirrosis puede facilitar la presencia de sobrecrecimiento bacteriano intestinal (SBI). Este, a su vez, puede conducir a la aparición de translocación bacteriana (TB). El objetivo principal del estudio fue evaluar el efecto de la administración de cisapride sobre el SBI y la TB en la cirrosis. Se utilizó el modelo de cirrosis experimental en ratas mediante la administración de tetracloruro de carbono. Dos grupos de ratas cirróticas recibieron cisapride o placebo durante 7 días y se evaluaron en ellas la presencia de SBI y de TB. Por otra parte se se obtuvo y se cultivó fluido yeyunal de un total de 46 pacientes cirróticos a fin de determinar la presencia de SBI por gérmenes gram-negativos. Aquellos pacientes en los que se detectó SBI por gram-negativos fueron aleatorizados para recibir o no cisapride por vía oral (20 mg / 12 h) durante una semana. En las ratas cirróticas, la administración de cisapride redujo significativamente la presencia de SBI. En 23 de los 46 pacientes cirróticos evaluados se detectó SBI, que en 10 casos fue causado por gérmenes gramnegativos. En los pacientes tratados con cisapride se observó un descenso significativo en el tiempo de tránsito orocecal, así como una desaparición del SBI por gram-negativos en la mayoría de ellos (4/5). Por el contrario en los en todos los pacientes no tratados persistió el SBI por gram-negativos. En las ratas cirróticas la administración de cisapride se acompañó de una reducción significativa tanto del SBI como de la TB. En conclusión, estos resultados sugieren que los agentes procinéticos pueden ser útiles en la prevención de la TB en la cirrosis.

Deranged intestinal motility, which occurs in cirrhosis, may facilitate the development of intestinal bacterial overgrowth (IBO), which can lead to bacterial translocation (BT). To asses the effect of cisapride on IBO and BT in cirrhosis, cirrhotic rats received cisapride or a placebo for 7 days and measurements of jejunal bacterial content and BT studies were performed. In addition, jejunal fluid from 46 cirrhotic patients was obtained for quantitative bacterial culture. Those patients in whom garm-negative IBO was detected were randomised to receive or not to receive cisapride (20 mg twice par day) for 1 week. Cisapride significantly reduced IBO in cirrhotic rats. Total IBO was documented in 23 of 46 cirrhotic patients, which was caused by gram-negative organisms in 10 cases. Orocecal transit time (OCT) significantly decreased after cisapride therapy, and was associated with the abolishment of bacterial overgrowth caused by gram-negative organisms in 4 out of 5 treated patients, whereas it persisted in non-treated cases. Cisapride administration to cirrhotic rats resulted in a reduction of the IBO, which is associated with a marked decrease in BT. These results suggest that prokinetic agents may be useful in preventing BT in cirrhosis.
