Abstract:Objective To study the efficacy and safety of double plasma molecular absorption system(DPMAS)in the treatment of pediatric acute liver failure(PALF).Methods A prospective analysis was performed on the medical data of children with PALF who were hospitalized in the Intensive Care Unit(ICU),Hunan Children's Hospital,from March 2018 to June 2020.The children were randomly divided into two groups:plasma exchange group(PE group)and DPMAS group(n=18 each).The two groups were compared in terms of clinical indices after treatment,laboratory markers before and after treatment,and adverse events after treatment.Results Compared with the PE group,the DPMAS group had a significantly lower number of times of artificial liver support therapy and a significantly shorter duration of ICU stay(P<0.05),while there was no significant difference in the 12-week survival rate between the two groups(P>0.05).There was no significant difference in laboratory markers between the two groups before treatment(P>0.05).After treatment,both groups had reductions in the levels of total bilirubin,interleukin-6,and tumor necrosis factor-α,and the DPMAS group had significantly greater reductions than the PE group(P<0.05).Both groups had a significant reduction in alanine aminotransferase(P<0.05),while there was no significant difference between the two groups(P>0.05).The PE group had a significant increase in albumin,while the DPMAS group had a significant reduction in albumin(P<0.05).The PE group had a significant reduction in prothrombin time,while the DPMAS group had a significant increase in prothrombin time(P<0.05).There was no significant difference between the two groups in the rebound rate of total bilirubin and the overall incidence rate of adverse events after treatment(P>0.05).Conclusions DPMAS is safe and effective in the treatment of PALF and can thus be used as an alternative to artificial liver support therapy.
