Abstract
BACKGROUND feline infectious peritonitis (FIP) is a fatal disease in cats classified as either effusive ('wet'), non-effusive ('dry'), or a mixture of both forms ('mixed'). The anti-FIP therapeutic effects of Mutian and molnupiravir, two drugs with a nucleic acid analog as an active ingredient, have been confirmed recently. METHODS Of the cats with FIP, we observed a total of 122 and 56 cases that achieved remission after the administration of Mutian and molnupiravir as routine treatments, respectively. Changes in clinical indicators suggested to be correlated with FIP remission (weight, hematocrit, and albumin-to-globulin ratio) before and after the administration of each drug and during follow-up observation were statistically compared for each FIP type. RESULTS In all three FIP types, the administration of either Mutian or molnupiravir resulted in statistically significant increases in these indicators. Furthermore, the effect of Mutian on improving the albumin-to-globulin ratio was not observed at all in wet FIP, as compared with that of molnupiravir, but statistically significant in mixed and dry (p < 0.02 and p < 0.003, respectively). The differences in albumin-to-globulin ratio were all due to those of circulating globulin levels. CONCLUSIONS These results indicate that slight inflammatory responses might be elicited continuously by a residual virus that persisted through molnupiravir treatments.

Abstract
The number of patients with fatty liver has been increasing worldwide; however, the significance of fatty liver in patients with chronic hepatitis B who are receiving nucleic acid analog (NA) therapy remains unclear. Thus, we aimed to determine whether fatty liver affects the development of hepatocellular carcinoma (HCC) in patients receiving NA therapy. This study included 445 patients who received NA therapy, and the development of HCC was investigated. The primary outcome was the association between fatty liver and HCC development. During a mean follow-up period of 7.4 years, 46 patients (10.3%) developed HCC. No significant difference in the cumulative incidence of HCC was observed between patients with fatty liver and those without (p = 0.17). Multivariable analysis for age, gender, platelet count, alanine aminotransferase level at 1 year following NA therapy, and fatty liver revealed that the presence of fatty liver was not a significant factor for HCC development (hazard ratio [HR]: 0.96, 95% confidence interval [CI]: 0.5-1.9). In another multivariable analysis for advanced fibrosis, gender, and fatty liver, advanced fibrosis was found to be a significant factor for HCC development (HR: 9.50, 95% CI: 5.1-18) but not fatty liver (HR: 0.90, 95% CI: 0.5-1.7). In conclusion, in patients with chronic hepatitis B who received NA therapy, advanced fibrosis was found to be an important risk factor for HCC development but not fatty liver, suggesting the importance of providing treatment before the progression of liver fibrosis regardless of the presence of fatty liver.

Abstract
Recent advances in antiviral therapy have enabled control of the hepatitis virus; however, these do not completely eliminate the pathological condition of liver disease, and portal hypertension remains a clinical problem. We herein report a case of hepatitis B virus/hepatitis C virus (HBV/HCV)-induced decompensated liver cirrhosis for which total management consisting of interventional radiology and endoscopy, based on the evidence of our clinical studies, followed by antiviral therapy for co-infection with HBV and HCV was successful. This case clearly indicates the effective timing of total management, suggesting that it prolongs the vital prognosis in addition to improving the hepatic function.

Abstract
With the introduction of methotrexate, biological disease-modifying antirheumatic drugs (bDMARDs), and targeted synthetic DMARDs (tsDMARDs), the disease activity of patients with rheumatoid arthritis has been dramatically ameliorated. However, these drugs have strong immunosuppressive effects and can cause reactivation of hepatitis B virus (HBV) in patients with resolved HBV infection. Corticosteroids or immunosuppressants used for other connective tissue diseases or vasculitis also carry a risk of inducing reactivation of HBV. Therefore, every rheumatologist should know how to detect the resolved infection of HBV in patients with rheumatic diseases receiving immunosuppressive therapy and how to monitor it when resolved infection is revealed. Of note, the cut-off index was changed from 2.1 log copies/ml to 20 IU/ml (1.3 Log IU/ml) in 2017. Rheumatologists should start nucleic acid analog administration at reactivation of HBV while performing ongoing immunosuppressive therapy in order to prevent severe or fulminant hepatitis. A low titer of HBs antibody (Ab) or lack of HBs Ab is a risk factor of reactivation of HBV. However, the reactivation of HBV cannot be prevented by HBs Ab titers at baseline or changes overtime. Rheumatologists should recognize that every immunosuppressive therapy, regardless of the mode of action, has a potential risk of reactivation. To facilitate proper management of patients with HBV infection, collaboration between rheumatologists and hepatologists is strongly encouraged. Patients' education, systems for checking electronic medical charts, and multidisciplinary efforts are considered important for detecting HBV reactivation.
