Clinical research of plasma exchange with continuous veno-venous hemofiltration in treating mid- and late-stage chronic severe viral hepatitis B patients / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the clinical efficacy and study the mechanism of combining plasma exchange and continuous veno-venous hemofiltration in treating patients with chronic severe viral hepatitis B in their mid- and late stages.</p><p><b>METHODS</b>94 patients suffering from chronic severe viral hepatitis B were divided into three groups. 29 patients were treated with plasma exchange plus continuous veno-venous hemofiltration (group A). 31 patients were treated with plasma exchange alone (group B). 34 patients received routine treatment (group C). The efficacy of treatment and survival rate of the three groups was investigated. Before and after artificial liver support system treatment the levels of cytokine were examined.</p><p><b>RESULTS</b>In group A, hyponatremia improved, the levels of interleukin 8 (IL-8) obviously decreased, the level of IL-10 increased, 5 of the 10 patients in coma regained normal consciousness (50.0%) and their survival rate was 48.3%. In group B, hyponatremia did not change, the level of IL-8 and IL-10 did not change. 2 of 11 patients in coma regained normal consciousness (18.2%) while survival rate was 22.6%. In group C, 1 of 11 patients in coma regained normal consciousness (9.1%) while survival rate was 20.6%.</p><p><b>CONCLUSIONS</b>It shows that plasma exchange with continuous veno-venous hemofiltration in treating patients with mid- and late stage chronic severe viral hepatitis B can increase the survival rate. IL-8 can be significantly removed, IL-10 significantly increased. This combined therapy is easy to practice, and should be used as an artificial liver support system.</p>
