A 67-year-old man with primary lung adenocarcinoma was hospitalized due to massive bilateral pleural effusion and pericardial effusion after 94 cycles of nivolumab therapy. We were unable to identify the cause of these effusions using blood tests, cytology tests, or bacterial culture of pleural effusion and thoracoscopy. ⋯ This case may support the introduction of corticosteroids for late-onset pleural and pericardial effusion during immune checkpoint inhibitor (ICI) treatment. However, the safety of rechallenge of ICIs after the improvement of fluid accumulation is controversial.

Eosinophilic granulomatosis with polyangiitis (EGPA) is an anti-neutrophilic cytoplasm antibody (ANCA)-associated vasculitis characterized by asthma and eosinophilia. Although EGPA involves multiple organs, ocular involvement is infrequent and often carries a poor visual prognosis. We herein report a rare case of EGPA presenting with central retinal artery occlusion (CRAO) in which visual loss developed during treatment with anti-interleukin (IL)-5 receptor monoclonal antibody, and improvement in visual outcomes was attained after treatment combining high-dose oral corticosteroids, cyclophosphamide and an anticoagulant. Physicians should consider CRAO as an ophthalmic manifestation of EGPA in patients with severe eosinophilic asthma.

Successful Management of Subacute Thyroiditis Following SARS-CoV-2 Infection: A Case Report.
Subacute thyroiditis (SAT) is a disorder of the thyroid gland and difficult to diagnose. It is probably triggered by a viral infection. Recently, several articles have reported SAT after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). ⋯ After SARS-CoV-2 infection, some patients can develop not only pneumonia but also SAT. Thus, a careful follow-up is recommended for patients after SARS-CoV-2 infection. Furthermore, the effect of SARS-CoV-2 infection on thyroid dysfunction should not be ignored.

Direct-acting antiviral (DAA) therapy carries a potential risk of inducing hepatitis B virus (HBV) reactivation. However, the HBV kinetics during and after DAA therapy in patients co-infected with hepatitis C virus (HCV) and HBV remain unknown. We retrospectively evaluated the HBV kinetics during and after sofosbuvir/ribavirin therapy in four HBV inactive carriers co-infected with HCV. ⋯ Changes in HBV-DNA levels during treatment differed among patients. The hepatitis B surface antigen (HBsAg) levels uniformly decreased (mean -0.530 logIU/mL) by the end of treatment and returned to near the baseline in all patients. Sofosbuvir/ribavirin therapy thus demonstrated a suppressive effect on HBsAg.

Objective Whether or not adaptive servo-ventilation (ASV) is effective in preventing arrhythmias in patients with heart failure (HF) due to ischemic heart disease (IHD) is unclear. This study estimated the effects of ASV therapy on arrhythmias in patients with HF due to IHD. Methods One hundred and forty-one consecutive hospitalized patients with HF due to IHD (mean age: 74.9±11.9 years old) were retrospectively assessed in this study. ⋯ ASV therapy was associated with a reduced incidence of arrhythmia after adjusting for demographic and cardiovascular disease risk factors (odds ratio, 0.27; 95% confidence interval, 0.11 to 0.63; p<0.01; compared to the Non-ASV group). In addition, at the 1-year follow-up, an improvement (increase) in the eGFR was found in the ASV group but not in the Non-ASV group. Conclusion ASV therapy was able to prevent arrhythmias, including PAF and VT, with short-term improvements in the renal function in patients with HF due to IHD.
