    Abstract:
    Minimal hepatic encephalopathy (MHE), a complex neuropsychological complication of cirrhosis, is characterized by delayed reaction time and the inhibition of abnormal response. This network meta-analysis (NMA) was adopted to compare the efficacy of five drugs including lactulose, probiotics, rifaximin, acetyl-L-carnitine (ALC), and L-Ornithine L-aspartate (LOLA) in the treatment of MHE. The Cochrane Library, PubMed, and Embase databases were searched for any existing entail on these five drugs from the inception to February 2018, including Randomized controlled trials (RCTs). The NMA of the five drugs, accounting for both direct and indirect comparisons to assess WMD (weighted mean difference) and SUCRA (surface under the cumulative ranking curves) was conducted. In total, 10 RTCS with 826 MHE patients met the inclusion criteria and were included in the NMA. The meta-analysis revealed that compared with placebo, lactulose, and probiotics had better efficacy in reducing ammonia serum levels and total SIP (Sickness Impact Profil) score; ALC had better efficacy in lowering serum level of ammonia and increasing the serum level of albumin; rifaximin and LOLA had better efficacy in reducing total SIP score. The results from SUCRA revealed that in terms of ammonia and albumin serums, ALC presented with the highest rankings when it comes to efficacy (serum ammonia: 87.2%; serum albumin: 92.25%). Hence, the key findings from the present study highly suggested that ALC had the best efficacy in the treatment of MHE patients.
