ObjectiveTo learn the outcomes of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) cases after artificial liver support system (ALSS) treatment and the relevant factors correlated with the clinical outcomes. MethodsIn the period from January 2011 to June 2014, 321 patients with HBV-ACLF were admitted to West China Hospital. The clinical data at baseline, before and after treatment were analyzed by univariate and multivariate logistic regressions to identify the independent risk factors correlated with 30-day outcomes. ResultsOf all the 321 patients, 233 survived and 88 died by the end of a 30-day observation. The univariate analysis identified that the incidences of cirrhosis, hepatorenal syndrome and peritonitis in the death group were significantly higher (P<0.05). The model for end-stage liver disease values, white blood cells (WBC), blood ammonia, creatinine and total bilirubin (TBIL) at different stages in the death group were significantly higher than those in the survival group (P<0.05). In the death group, the HBV-DNA, TBIL decrease after triple ALSS treatments, baseline prothrombin time activity (PTA) and PTA level after triple ALSS treatments were significantly lower (P<0.05). The multivariate logistic regression indicated that WBC (OR=2.337, P<0.001) and TBIL level after triple ALSS treatments (OR=4.935, P<0.001) were independent predicting factors for death within 30 days after ALSS treatment; HBV-DNA (OR=0.403, P<0.001), the decrease of TBIL after triple ALSS treatments (OR=0.447, P<0.001) and PTA level after triple ALSS treatments (OR=0.332, P<0.001) were protecting factors for the 30-day prognosis. ConclusionThese five factors including WBC, HBV-DNA, PTA, TBIL and TBIL decrease after triple ALSS treatments influence the short-term prognosis for HBV-ACLF patients, which are valuable for decision making in clinical practices.
ObjectiveTo summarize the changes and mechanism of related genes induced by stem cell therapy in acute-on-chronic liver failure (ACLF) in recent years, and in order to guide the clinical value of ACLF and curative effect evaluation. MethodsThrough searching Wanfang med, CNKI, Pubmed database and so on in recent years, the differentially expressed genes induced by stem cell therapy for ACLF in recent years was retrieved and the changes of related genes induced during the treatment process were discussed. ResultsBoth at home and abroad had reported that stem cell therapy in the process of ACLF caused mir-27b, TRAIL, and Tg737 genetic changes, some genetic changes had an fixed change trend. ConclusionsStem cells in the treatment of ACLF, cause mir-27b, TRAIL, Tg737 genetic changes, which can provides a new way and method for monitoring stem cell therapy ACLF.
