Outline of Final Research Achievements

Albumin is produced only in the liver, and hypoalbuminemia occurs as the disease progresses in patients with cirrhosis. Hypoalbuminemia causes edema and pleural effusions, which impair activities of daily living and hinder the treatment of hepatocellular carcinoma, resulting in a shortened overall survival rate. The treatment includes supplementation with albumin from donated blood and nutritional therapy with branched-chain amino acid products, its effects are limited. We have started a clinical trial of cell therapy for deficiency of lipid metabolism enzymes, which are produced only in the liver like albumin. In this study, we aimed to introduce an albumin-producing plasmid into adipocytes and to establish albumin-producing adipocytes, which unfortunately was not achieved.

Academic Significance and Societal Importance of the Research Achievements

進行した肝硬変患者への長期間のアルブミン投与は、腹水や浮腫の改善をもたらすのみではなく、肝硬変に伴うその他の合併症や生命予後を改善することが報告されており、アルブミンの長期投与が推奨されている(Lancet 2018)。医薬品としての血漿由来ヒト血清アルブミンは医療の現場で広く用いられており、その有用性も確立されているが、供給量が限られていることなどが問題となっている。その他の治療法として分岐鎖アミノ酸製剤による栄養療法が行われるが、その治療効果は限定的である。新たなアルブミン補充の方法が待たれる状況であり、アルブミン産生細胞系統の樹立はその有力な解決策となり得た。
