Recently, two conflicting articles about recurrence of hepatocellular carcinoma (HCC) after direct acting antivirals (DAA) against hepatitis C virus (HCV) were published. We investigated the relationship between DAA and HCC recurrence. Eligible patients were (1) history of HCC and treated curatively with interventions, and (2) interferon-free DAA therapy was initiated after eradication of HCC. We analyzed contributing factor for HCC recurrence. Ten out of 23 participants (43%) encountered recurrence of HCC. Age, sex, diabetes mellitus, fibrosis score, chemistry, and alpha-fetoprotein did not differ between patients with recurrence and patients without recurrence. The patients with recurrence had significantly higher values of antibody to hepatitis B core antigen (anti-HBc) than the patients without recurrence, 6.06±3.75 vs. 0.91±2.43 (p=0.0019). The relative risk of HCC recurrence comparing anti-HBc positive to negative was 5.2 (95% confidence interval 1.40 to 19.32). Odds ratio was 22.0 (95% confidence interval 2.5 to 191.1). We conclude that anti-HBc positivity was a strong contributing factor for HCC recurrence after DAA therapy.

Spontaneous rupture is one of the most fatal complications of hepatic tumors such as hepatocellular carcinoma. In fact, many studies have shown that the in-hospital and 30-d mortality rates are as high as 25%-100%. Cholangiolocellular carcinoma (CoCC) is a rare primary hepatic tumor, usually small in size, that is thought to originate from the ductules and/or canals of Hering. Here, we present a case of spontaneous rupture of a CoCC that was successfully resected by radical surgery. Although CoCC is a rare primary hepatic tumor, it demonstrates certain specific clinical features, including a better prognosis than for other primary liver cancers, and thus should be distinguished from those other cancers. Moreover, CoCC can appear as a ruptured huge tumor, and when it does, radical hepatectomy can be an effective measure to achieve both absolute hemostasis and curability of tumor.

シトルリン血症は尿素サイクルの一つであるアルギニノコハク酸合成酵素 (ASS) の欠損, あるいは活性低下により高シトルリン血症および高アンモニア血症を呈して意識障害を発現する, 常染色体劣性遺伝を示す疾患である. 本症例は幼児期から学業成績不良で, 青年期にはナルコレプシーやてんかんと診断され, 平成12年に刑事事件を起こし, 精神鑑定で精神病と認定された. その後に肝硬変・肝細胞癌が発見され, 右葉切除を受けていた. 今回, 他医でブドウ糖7.5%加アミノ酸製剤の輸液を契機に昏睡状態となり当院救命救急センターに搬入され, 血漿アンモニア値の著増から血漿アミノ酸分析を行い, シトルリンが高値であったため分子遺伝学的検索を行った. その結果, SLC25A13遺伝子の変異を認め成人発症II型シトルリン血症(CTLN2)と診断された.
