Background: In 1984, Gleich et al. described 4 patients with episodic angioedema associated with eosinophilia (EAE), which was characterized by recurrent episodes of angioedema and urticaria, eosinophilia, elevated serum IgM, fever, increased body weight and a benign course without involvement of the internal organs demonstrating that it was a clinical entity distinct from the hypereosinophilic syndrome. Thereafter, 37 cases of EAE have been reported in Japan, 33 cases of which, although similar, had a different evolution from classical EAE. Objective: To describe 4 cases and review the cases of angioedema associated with eosinophilia reported in Japan. Results: Four Japanese female patients had persistent angioedema mainly involving the hands and lower legs, and eosinophilia which resolved within a few months. The review of the 37 cases of EAE in the Japanese literature demonstrated that in 33 cases, there were common characteristics which differed from EAE. These included: (1) the absence of recurrent attacks; (2) the predominance of young females (20–37 years, with a mean of 26 years); (3) the localization of the angioedema to the extremities; (4) the absence of increase in the serum IgM level, and (5) the effectiveness of low-dose prednisone or even the occurrence of spontaneous remission. Conclusion: We propose that persistent angioedema with eosinophilia can be classified into 2 types, i.e. one being an episodic (recurrent) type as reported by Gleich and a nonepisodic type as our 4 cases and others found in the Japanese literature.
The aim of this study was to investigate the early tumor response and safety of atezolizumab plus bevacizumab for patients with unresectable hepatocellular carcinoma in real-world practice. Forty patients with Child-Pugh class A liver function and eastern cooperative oncology group performance status 0 or 1 were enrolled. The objective response rate (ORR) at six weeks after the start of treatment, changes in α-fetoprotein (AFP) and des-γ-carboxyprothrombin, incidence of adverse events (AEs), and changes in albumin-bilirubin (ALBI) score and serum ammonia level, were evaluated. Among 40 patients, 24 had histories of prior molecular targeted agents (MTAs). The ORR was 22.5% based on mRECIST. Multivariate analysis showed that an AFP ratio <1.0 at three weeks (odds ratio 39.2, 95% confidence interval CI 2.37–649.0, p = 0.0103) was the only significant factor for predicting early response. There was no significant difference in the frequency of AEs between patients receiving first-line treatments and others. Fatigue, proteinuria, and ascites were more frequent in patients who experienced prior treatment. No decrease in ALBI score or increase in serum ammonia level was observed. Our study demonstrated that AFP may be useful in assessing early response and that this treatment is safe, including in patients with prior MTA treatments.
Recently, a distinct vascular pattern in hepatocellular carcinoma (HCC) called vessels encapsulating tumor‐forming clusters (VETC) has received attention because of its association with poor prognosis. However, little is known about the mechanism by which VETC promotes an aggressive phenotype at the molecular level. In our study, the association between differences in stepwise signal intensity in the HB phase and molecular subtypes and somatic mutations associated with the immune microenvironment were investigated using the International Cancer Genome Consortium (ICGC) cohort (66 patients). To our knowledge, this is the first study to analyze the molecular patterns of VETC using RNA‐Seq data. The VETC+ HCC group showed significantly lower overall survival and higher cumulative incidence of extrahepatic metastasis after curative hepatic resection than the VETC− HCC group. The VETC+ group exhibited molecular features indicative of lower immune activation than the VETC− group, suggesting that tumor cells in the VETC+ group were more likely to escape from the immune response, which could lead to the shorter OS (Overall survival) and higher risk of metastasis. On the other hand, gene expression levels of fibroblast growth factor receptors were upregulated in VETC+ HCC, suggesting that VETC+ HCC might benefit from lenvatinib treatment. Our results demonstrate that VETC+ HCC was associated with the suppression of tumor immune responses at the molecular level.
Aim: Patients with chronic liver diseases (CLD) suffer from a variety of subjective symptoms, and the assessment of healthrelated quality of life (HRQOL) is crucial. The Chronic Liver Disease Questionnaire (CLDQ) is the first liver disease-specific instrument for this purpose. In this study we aimed to develop the Japanese version of CLDQ and to assess its validity and reliability in Japanese patients with chronic viral hepatitis.Methods: The participants included 135 Japanese patients chronically infected with hepatitis B or C virus. The Japanese version of the CLDQ was developed according to the standard "back-translation" method. In addition to the Japanese version of the CLDQ, we asked the patients to fill out two other selfreport questionnaires: the Japanese versions of the 36-Item Short Form Survey (SF-36) and Hospital Anxiety and Depression Scale (HADS). Then, the internal consistency, convergent and discriminant validity of the Japanese version of CLDQ were statistically examined.Results: Cronbach's alpha of the Japanese version of the CLDQ was acceptable. The mean score was lower in emotional domains of the CLDQ, compared with those in somatic domains. Pearson correlations between Japanese CLDQ and SF-36 and HADS were significant. The mean of the CLDQ scores decreased in all domains in patients with liver cirrhosis compared with those in patients with chronic hepatitis. Conclusion:The Japanese version of the CLDQ is a reliable and valid instrument for assessment of the HRQOL of Japanese patients with chronic viral hepatitis. The results also suggest that the HRQOL of Japanese patients is mainly impaired by emotional factors rather than somatic symptoms, and significantly worsened by progression of the disease.
