BACKGROUND: The pathogenesis of hepatic encephalopathy is still not completely clear at present, and the theory of ammonia poisoning may be the most powerful, the mechanism for lactulose in decreasing ammonia is clearer, and there are many studies on hepatic encephalopathy treated by lactulose at home and aboard, but the comparative studies on the long-term and short-term treatment of lactulose and placebo control treatment are still in lack. OBJECTIVE: To given long-term and short-term treatment of lactulose to patients with minimal hepatic encephalopathy, and compare the effect on the quality of life (QOL) of the patients with minimal hepatic encephalopa thy. DESIGN: A case-control observation. SETTING: Department of Geriatrics, Guangzhou First People's Hospital. PARTICIPANTS: Sixty patients with minimal hepatic encephalopathy, who were abnormal in the number connection test (NCT), digital symbol test (DST) and/or evoked potential examination and cooperated with the treatment, were selected from the patients with cirrhosis treated in the De partment of Geriatrics of Guangzhou First People's Hospital between June 1998 and March 2002, and they were randomly divided into control group (n=20), short-term lactulose group (n=20) and long-term lactulose group (n=20). METHODS: All the patients were given vitamin B for 24 weeks, two tablets for each time, three times a day; besides, the patients in the short term lactulose group and long-term lactulose group were orally adminis tered with lactulose (15-90 mL per day) for 8 and 24 weeks respectively. They were assessed with WHOQOL-BREF at the end of 0, 8, 16 and 24 weeks respectively, the incidence rate of hepatic encephalopathy was observed, and the ammonia conc entration in blood was detected at the same period.MAIN OUTCOME MEASURES: The changes of QOL and ammonia concentration in blood during the treatment were observed.RESULTS: During the treatment, one case in the control group lost to the follow-up, one case in the short-term lactulose group died from traffic accident, and two cases in the long -term group quitted because they could not endure the side effect of diarrhea, and totally 56 cases finished the treatment and entered the analysis of results. ① The incidence rate of hepatic encephalopathy at 6 months was 40%(8/20), 30%(6/20), 5%(1/20) in the control group, short-term lactulose group and long-term lactulose group respectively, and it was significantly lower in the long-term lactulose group than in the control group and short-term lactulose group (P < 0.05), but there was no significant difference between the short-term lactulose group and control group (P > 0.05). ② At 8, 16 and 24 weeks after treatment,the score of environment in QOL had no significant difference among the control group, short-term lactulose group and long-term lactulose group (P > 0.05), but there were significant differences in the scores of physiology,psychology and social relationship (P < 0.05); At 8 weeks, there were more obvious differences in the long-term lactulose group and short-term lactulose group than in the control group, but no significant difference between the long and short-term lactulose groups; At 16 weeks, there were more obvious differences in the long-term lactulose group than in the short-term lactulose group and control group, but no significant difference between the short-term lactulose group and control group; At 24 weeks, the long-term lactulose group had more improvements than in the control group and short-term lactulose group. ③ At 16 and 24 weeks after treatment, the ammonia concentrations in blood were significantly decreased in the long-term lactulose group as compared with the control group and short-term lactulose group.CONCLUSION: The long-term treatment of lactulose can improve the QOL of patients with minimal hepatic encephalopathy, eventually reduce the incidence of hepatic encephalopathy and decrease the ammonia concentration in blood; However, the short-term treatment of lactulose could not.
