We herein report a patient with giant cell arteritis (GCA) who developed pneumatosis intestinalis (PI) while she was in a clinically sustained remission phase. A 79-year-old woman with GCA involving the thoracic aorta and its first branches to the posterior tibial arteries had been treated with high-dose prednisolone. Nine weeks after initiating treatment and while in clinically sustained remission with a normal CRP level, PI and pneumoperitoneum were incidentally found during scheduled positron emission tomography-computed tomography, which also revealed slight residual inflammation of GCA. This is a very rare case of PI complicated by GCA, and we discuss the possible relationships.

Diffuse alveolar hemorrhaging (DAH) due to oral anticoagulation (OAC) is a life-threatening condition that leads to severe respiratory failure. There is a clinical dilemma in that OAC-induced DAH often forces the discontinuation of OAC therapy and the administration of high-dose corticosteroids, which increases the risk of stroke and cardiovascular events. We herein report the first case of OAC-induced DAH and atrial fibrillation (AF) in a patient who completely discontinued OAC therapy and high-dose corticosteroids after experiencing percutaneous left atrial appendage (LAA) occlusion. This case suggests that percutaneous LAA closure may aid in the management of OAC-induced DAH and AF.

A 70-year-old man received pembrolizumab as a second-line treatment for squamous cell lung cancer of the lower right lobe. After three courses, proteinuria and hematuria were observed, which worsened after seven courses. ⋯ Renal dysfunction as an immune-related adverse event of pembrolizumab monotherapy for non-small cell lung cancer has been reported previously. Therefore, establishing a system for the early detection and treatment that distinguishes immune-related glomerular diseases is essential.

We herein report a 60-year-old woman who experienced severe flare of rheumatoid arthritis (RA) and Epstein-Barr virus (EBV) positivity following administration of the messenger ribonucleic acid (mRNA)-type severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine. Since 40 years old, she had been in long-term remission of anti-citrullinated protein antibody-positive RA. ⋯ Tocilizumab was introduced to treat RA. The RA disease activity disappeared, and anti-EA DR IgG and EBV-DNA became negative.

A 54-year-old Japanese woman was admitted to our ward because of recurrent chest pain at rest for 2 months. She had been treated with nivolumab, an immune checkpoint inhibitor for inoperable advanced hypopharyngeal cancer for 21 months. ⋯ Benidipine 8 mg was started, and she had no chest pain even after resuming therapy with nivolumab. Vasospastic angina is an adverse effect of nivolumab.
