Conclusion Oral zinc supplementation improved performance on the number connection test , but no evidence about other clinical or biochemical outcomes was available
Background and aim Because low serum zinc levels precipitate hepatic encephalopathy , zinc supplementation is considered a potential therapeutic option .
The aim of this study was to assess the effects of oral zinc supplementation in the treatment of hepatic encephalopathy .
Management of hepatic encephalopathy with oral zinc supplementation: a long-term treatment.
OBJECTIVES The effect of long-term oral zinc supplementation , in addition to st and ard therapy ( protein-restricted diet and lactulose ) on recurrent hepatic encephalopathy , was assessed in a double-blind study . METHODS Ninety cirrhotic patients with stable recurrent hepatic encephalopathy , after following a one month period of st and ard therapy , were r and omized to receive oral zinc acetate supplementation ( 600 mg/day ) in addition to st and ard therapy or to continue only st and ard therapy ( a diet containing 0.8 g/kg/day of protein and 90 g/day of lactulose ) for six months . Psychometric tests , NCT ( number correction test ) and PSE ( portal-systemic encephalopathy ) Index , were used to evaluate the degree of hepatic encephalopathy , both at the beginning and the end of each treatment period . RESULTS Oral zinc supplementation in addition to st and ard therapy was able to normalize serum zinc levels .  The patients who never showed clinical signs of hepatic encephalopathy during the trial were 88.6 % in zinc-group and 86 % in only st and ard therapy group . Psychometric tests , NCT and PSE Index , were statistically better than basal values either in zinc-group or in only st and ard therapy group . CONCLUSIONS Final values of psychometric tests were better in zinc-group than only st and ard therapy group but the differences were not statistically significant
