Aim: The objective of this systematic review and meta‐analysis was to assess the efficacy of probiotics and synbiotics in patients with hepatic encephalopathy. Methods: Eligible trials were identified by searching electronic databases including MEDLINE, the Cochrane Library, Science Citation Index and Embase, abstract proceedings, reference lists and ongoing trial registers until 13 October 2010. We included randomized controlled trials comparing probiotics and synbiotics with no intervention, placebo or lactulose in patients with hepatic encephalopathy. The primary outcome measure was improvement in hepatic encephalopathy. Results were expressed as risk rates (RR) with confidence intervals (CI) and intertrial heterogeneity as I2. Results: Seven trials with a total of 393 patients were analyzed. Compared to placebo or lactulose, treatment with probiotics or synbiotics significantly improved hepatic encephalopathy (RR = 1.40, 95% CI = 1.05–1.86, I2 = 5%). Probiotics decreased arterial ammonia (weighted mean difference 15.95; 95% CI = 26.72–3.28; I2 = 68%), but not venous ammonia (weighted mean difference 5.23; 95% CI = 21.77–11.30; I2 = 89%). Treatment with probiotics or synbiotics did not significantly affect the psychometric tests. Overall adverse events were reported in four trials with no difference between probiotics and placebo groups (RR = 0.32, 95% CI = 0.04–2.57; I2 = 59%). Regression analysis showed evidence of small‐study effects. Conclusion: The present meta‐analysis suggests that probiotics may be an effective treatment of hepatic encephalopathy, though rigorous evaluation in standardized, randomized, clinical trial with clinically relevant outcomes is still needed. 相似文献

The Chinese Society of Hepatology developed the current guidelines on the management of hepatic encephalopathy in cirrhosis based on the published evidence and the panelists' consensus. The guidelines provided recommendations for the diagnosis and management of hepatic encephalopathy(HE) including minimal hepatic encephalopathy(MHE) and overt hepatic encephalopathy, emphasizing the importance on screening MHE in patients with end-stage liver diseases. The guidelines emphasized that early identification and timely treatment are the key to improve the prognosis of HE. The principles of treatment include prompt removal of the cause, recovery of acute neuropsychiatric abnormalities to baseline status, primary prevention, and secondary prevention as soon as possible. 相似文献

Management of hepatic encephalopathy (HE) primarily involves avoidance of precipitating factors and administration of various ammonia-lowering therapies such as nonabsorbable disaccharides and antimicrobial agents like rifaximin. The nonabsorbable disaccharides which include lactulose and lactitol are considered the first-line therapy for the treatment of HE and minimal hepatic encephalopathy (MHE). Lactulose significantly improves cognitive function and health-related quality of life in patients with MHE. Lactitol is comparable to lactulose in the treatment of HE with fewer side effects. Lactulose has also shown to be effective in primary and secondary prophylaxis of HE. Disaccharides were found to be comparable to rifaximin in recent systemic reviews in the treatment of HE however conclusion was based on inclusion of some poor quality trials. Combination therapy of disaccharides either with rifaximin, L-ornithine L-aspartate,probiotics for the treatment of HE needs further validation in large studies. 相似文献

Minimal hepatic encephalopathy represents a part of the spectrum of hepatic encephalopathy and is the mildest form. While patients with hepatic encephalopathy have impaired intellectual functioning, personality changes, altered levels of consciousness, and neuromuscular dysfunction, patients with minimal hepatic encephalopathy have no recognisable clinical symptoms of hepatic encephalopathy but have mild cognitive and psychomotor deficits. The prevalence of minimal hepatic encephalopathy has been reported to vary between 30% and 84% in patients with liver cirrhosis and is higher in patients with poor liver function. The diagnosis is usually made by neuropsychological and/or neurophysiological testing in cirrhotic patients who are otherwise normal on neurological examination. Minimal hepatic encephalopathy is a clinically significant disorder that impairs the health-related quality of life, predicts the development of overt encephalopathy and is probably associated with a poor prognosis. Thus screening all patients with cirrhosis for minimal hepatic encephalopathy using psychometric testing is recommended. Pharmacologic therapy is recommended for patients diagnosed with minimal hepatic encephalopathy. The pathogenesis of minimal hepatic encephalopathy is considered similar to that of overt hepatic encephalopathy and ammonia plays a key role. Thus ammonia lowering agents such as lactulose, L-ornithine and L-aspartate that have good safety profiles are recommended. Future studies will better define the role of probiotics, levocarnitine and sodium benzoate. 相似文献

Modulation of intestinal flora through the use of probiotics is an emerging therapeutic strategy in the management of chronic liver diseases. This article focuses on the pathophysiologic basis for using probiotics in liver disease and reviews the existing literature on the subject. The role of probiotics is examined in the following areas: a) prevention of infection, b) the hyperdynamic circulatory state of cirrhosis, c) hepatic encephalopathy, d) liver function, and e) nonalcoholic fatty liver disease. 相似文献

隐匿性肝性脑病(minimal hepatic encephalopa-thy,MHE)又称亚临床肝性脑病(subclinicalhepatic encephalopathy,SHE),是慢性肝病和肝硬化最常见的严重并发症,是一种具有渐进性、可逆性的神经精神病学异常和运动功能失调特点的疾病.尽管其发病机制仍未明确,血清和中枢神经系统(central nervoussystem,CNS)血氨升高仍被认为是肝性脑病(hepatic encephalopathy,HE)的致病机制和治疗核心,并受血脑屏障改变、神经递质紊乱、氨基丁酸和苯二氮异常等因素影响.因此明确其诱发因素是HE治疗的关键.治疗药物包括抗生素、二糖类、益生菌、门冬氨酸鸟氨酸(L-ornithine-L-aspartate,LOLA)、苯甲/苯乙酸盐等.因此,对MHE的发病机制、临床诊断和治疗研究进展进行归纳,为临床诊疗提供前沿性、系统性信息,具有重要意义. 相似文献
