The present study aimed to investigate the incidence of hepatocellular carcinoma (HCC) and factors related to HCC occurrence after direct-acting antiviral (DAA) treatment in the Fukushima Liver Academic Group (FLAG). We conducted a multicenter retrospective cohort study of 1068 patients without cirrhosis (NC) or with compensated liver cirrhosis (LC) who achieved a sustained virologic response (SVR). First, we compared the cumulative HCC incidence and survival rates in NC (n = 880) and LC (n = 188) patients without a history of HCC treatment. Second, we performed multivariate analysis of factors related to HCC occurrence after DAA treatment. Overall, the average age was 65 years, and the male/female ratio was 511/557. Thirty-nine (4%) patients developed HCC. The cumulative 4-year HCC incidence and survival rates were 3.0% and 99.8% in NC patients and 11.5% and 98.5% in LC patients, respectively. The independent factors affecting HCC occurrence identified by multivariate analysis were the serum albumin (ALB) level before SVR for NC patients and the ALBI score, platelet count, and diabetes before SVR for LC patients. The factors related to HCC occurrence differed between NC and LC patients. Careful surveillance of post-SVR patients with these risk factors is needed.
We report a series of five patients with autoimmune hepatitis (AIH) accompanied by systemic lupus erythematosus (SLE) (AIH-SLE overlap). Serologic tests showed that all patients were positive for antinuclear antibody and double-stranded DNA antibody. Histological examination of the liver showed that three of the patients had chronic hepatitis with severe activity. One of the other two had acute and severe hepatitis with submassive necrosis in both portal and lobular areas. The last patient already had liver cirrhosis. All patients had a mild form of SLE and showed a rapid response to corticosteroid. There was no serious involvement of organs other than the liver in any of the patients, and the prognoses were comparatively good in all patients.
A 23-year-old man was admitted to our department due to hemorrhage from gastric varices. He had been diagnosed as having Wilson's disease at the age of 17. Abdominal ultrasonography and computed tomography (CT) showed portal thrombosis and a large mass occupying most of the right lobe in the liver. The tumor was diagnosed as hepatocellular carcinoma (HCC) by image views and tumor markers. He died 3 months after the diagnosis, and an autopsy was performed. Histologic examination of the tumor showed moderately to poorly differentiated HCC. The nontumorous lesion of the liver revealed cirrhosis. HBX-DNA sequence was not detected in the liver. Hepatic cirrhosis is a well-recognized complication of Wilson's disease, but HCC is extremely rare. We describe the clinical findings of this patient and discuss the relationship of the development of HCC with a review of the relevant literature.
To clarify the clinicolaboratory characteristics of patients with primary biliary cirrhosis (PBC) -autoimmune hepatitis (AIR) overlap, we analyzed their clinicolaboratory findings and compared them with those of patients with AIR or PBC retrospectively. We analyzed the laboratory findings of 177 patients that diagnosed 103 PBC and 74 AIR patients at our department during the period from January 1990 to April 2005. Of 103 PBC patients with a diagnosis of PBC, we identified 10 cases (9.7%) of PBC-AIR overlap (2 male, 8 female; mean age 56.5 years) . PBC preceded AIH in 2 patients, and both diseases occurred simultaneously in the other 8 patients. There is no patients AIR preceded PBe. Positive frequency of anti-smooth muscle antibody (ASMA), IgG and IgM levels were significantly higher in patients with overlap than in those with AIR or PBC. Ursodeoxychoric acid (UDCA) was administered to all 10 patients initially, and later an immunosuppressant, prednisolone or azathioprine, was added in 6 patients. Two of the 10 patients died of liver failure 5 and 12 years after diagnosis, respectively. Both patients had been treated by either prednisolone or UDCA alone. We conclude that in patients with PBC-AIH overlap, the clinical characteristics of both PBC and AIR exist in an enhanced manner.
