RESUMEN
To compare the accuracy of standard model for end-stage liver disease (MELD) score with that of four MELD-based scores incorporating serum sodium (SNa) to predict three- and six-month mortality in cirrhotic patients after their placement on the waiting list for liver transplantation (LT). A cohort study was performed. Receiver operating characteristic (ROC) curves were generated for MELD, MELD incorporating SNa (MELD-Na, MELD-Na2), integrated MELD (iMELD), and MELD to SNa ratio (MESO) index to assess the predictive accuracy of these scores to determine three- and six-month mortality. The c-statistic (area under the ROC curve [AUC]) was used to determine predictive power and the Cox proportional-hazard ratio to estimate death risk. We studied 558 patients. There was a statistically significant difference in the predictive accuracy of scores at three months (AUCs: MELD = 0.79 [95% CI = 0.72-0.87]; MELD-Na = 0.84 [95% CI = 0.78-0.90]; MELD-Na2 = 0.85 [95% CI = 0.80-0.91]; iMELD = 0.85 [95% CI = 0.80-0.90]; MESO = 0.81 [95% CI = 0.80-0.91]) and at six months (MELD = 0.73 [95% CI = 0.67-0.80]; MELD-Na = 0.79 [95% CI = 0.73-0.84]; MELD-Na2 = 0.80 [95% CI = 0.74-0.85]; iMELD = 0.80 [95% CI = 0.75-0.85]; MESO = 0.75 [95% CI = 0.69-0.81]) (p < 0.001). Death risk was independent of age and sex. Sodium-modified MELD scores are able to more accurately predict three- and six-month mortality among cirrhotic patients awaiting LT.

A encefalopatia hepática (EH) é um distúrbio funcional do sistema nervoso central (SNC) associado à insufi ciência hepática, de fisiopatologia multifatorial e complexa. Devido aos avanços no conhecimento sobre o manejo da EH na cirrose e na insuficiência hepática aguda (IHA), a diretoria da Sociedade Brasileira de Hepatologia (SBH) promoveu uma reunião monotemática acerca da fi siopatologia, diagnóstico e tratamento da EH, abordando aspectos controversos relacionados ao tema. Com a utilização de sistemática da medicina baseada em evidências, foram abordados o manejo da EH e da hipertensão intracraniana na IHA, o manejo da EH episódica na cirrose, as controvérsias no manejo da EH e a abordagem da EH mínima. O objetivo desta revisão é resumir os principais tópicos discutidos na reunião monotemática e apresentar recomendações sobre o manejo da síndrome votadas pelo painel de expertos da SBH.
Hepatic encephalopathy (HE) is a functional disorder of the central nervous system (CNS) associated with liver failure, either end-stage chronic liver disease or fulminant hepatic failure. Its pathogenesis remains complex and poorly understood. In view of recent advances in the management of HE, the Brazilian Society of Hepatology endorsed a monothematic meetingregarding HE in order to gather experts in the to discuss related data and to draw evidence-based recommendations concerning: management of HE and intracranial hypertension in FHF, treatment of episodic HE in cirrhosis, controversies in the management of EH including difficult to treat cases and diagnostic and treatment challenges for minimal HE. The purpose of this review is to summarize the lectures and recommendations made by the panel of experts of the Brazilian Society of Hepatology.
