title: [Vegetable protein diets with or without non-absorbable antibiotics for the treatment of chronic portal systemic encephalopathy].
abstract: Five patients with mild chronic portal systemic encephalopathy (PSE) were studied. The study was designed in a double cross over fashion in which each patient received during period I a 40 g vegetable protein diet as single treatment. During period II three g/day of oral kanamycin were added and then new periods of single vegetable protein diet (period III) and vegetable protein diet plus kanamycin (period IV) were introduced (identical to periods I and II respectively). Each period lasted two weeks. Several biweekly assessements-tests were determined including: mental state, asterixis grade, electroencephalograms, number connection tests, figure connection tests, blood ammonia levels and stool counts of total aerobes/anaerobes per g/feces were done. During the study none of the patients developed acute encephalopathy. In any case it was detected a significant improvement of the PSE parameters assessed with the addition of oral kanamycin. Fecal counts were very similar during the various periods of the study. We conclude that in mild portal systemic encephalopathy controlled with vegetable protein diet, the addition of non absorbable antibiotics is not mandatory for the management of these patients and may represent a potential risk of serious side effects. At the beginning of treatment vegetable protein diet should be administered and only in case of failure, antibiotics are to be indicated.
