[Efficacy and safety of coupled plasma filtration adsorption combined with continuous veno-venous hemofiltration for multiple organ dysfunction syndrome patients with acute liver failure].

OBJECTIVE: To evaluate efficacy and safety of coupled plasma filtration adsorption (CPFA) combined with continuous veno-venous hemofiltration (CVVH) for the treatment of multiple organ dysfunction syndrome (MODS) patients with acute liver failure (ALF), and to evaluate the effect of CPFA plus CVVF on inflammatory mediators in these patients.

METHODS: A total of 38 cases of 11 MODS patients with ALF (male 6, female 5) were treated with CPFA plus CVVH, and the following clinical indicators including changes in mean arterial pressure (MAP), oxygen index (PaO(2)/FiO(2)), tumor necrosis factor-alpha (TNF-alpha), interleukin-1 beta (IL-1 beta), IL-6, IL-8, biochemical parameters of liver and kidney function, parameters of systemic inflammatory response syndrome (SIRS) score, and acute physiology and chronic health evaluation II (APACHE II) score were determined before and after the treatment. The degree of improvement in clinical symptoms, feasibility, tolerance toward CPFA plus CVVH, therapy-related adverse reactions and security were simultaneously evaluated.

RESULTS: MAP increased by 12 mmHg (1 mmHg=0.133 kPa), and PaO(2)/FiO(2) increased by 40 mmHg after the application of CPFA plus CVVH (both P<0.05), along with significant decrease in TNF-alpha, IL-1 beta, IL-6, IL-8 and markedly lowered levels of serum total bilirubin (IBIL), direct bilirubin (DBIL), blood urea nitrogen (BUN), serum creatinine (SCr) and blood ammonia (all P<0.05). Besides, clinical symptoms, including urinary volume, mental disturbance, jaundice, debility, nausea, vomiting, fever, abdominal distention, anepithymia, and SIRS, APACHE II scores were improved significantly after the CPFA plus CVVH (all P<0.05). No therapy-related adverse reactions, including severe haemorrhage, shock, hypersensitivity, were noted, and patients tolerated well toward CPFA plus CVVH. The total survival rate of patients was 45.5% (5/11 cases) at the end of the treatment.

CONCLUSION: Our data indicate that CPFA combined with CVVH is an effective and safe method to improve the prognosis of MODS patients with ALF, the mechanism of which may be related to its effective removal of inflammatory cytokines.
