A man in his 70s visited our department for dyspnea with pulmonary infiltrate that was unresolved by antibiotics. He had been taking Sansoninto for five years and doubled its dose a month ago. After discontinuing Sansoninto without any additional medications, his symptoms gradually disappeared, and pulmonary infiltration improved. ⋯ We diagnosed this patient with Sansoninto-induced lung injury. Sansoninto is a combination drug that consists of sansonin, bukuryo, senkyo, chimo, and kanzo. This paper reports the first case of Sansoninto-induced lung injury and discusses the mechanism considering its components.

Rituximab is an effective treatment for frequently relapsing/steroid-dependent nephrotic syndrome, but there is concern about infections caused by humoral immunodeficiency. We herein report a case of prolonged (>7 weeks) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. ⋯ Treatment with casirivimab and imdevimab (REGEN-COV) monoclonal antibodies in combination with remdesivir resulted in complete clearance of the infection. The REGEN-COV antibody cocktail may improve the outcome of SARS-CoV-2 infection in patients with humoral immunodeficiency.

Case Reports
A Case of Native Aortic Valve Thrombus Complicating Intermittent Occlusion of a Left Main Coronary Artery.
Intermittent left main coronary artery ostium obstruction (LMOO) caused by native aortic valve thrombus (NAVT) is an extremely rare condition. It may therefore be challenging to identify the cause using only coronary angiography, even though the clinical presentation and electrocardiography (ECG) strongly suggest myocardial infarction. We herein report a 53-year-old man with NAVT complicating intermittent occlusion of left main disease in preexisting coronary artery stenosis.
