A 58-year-old Japanese woman with herpes zoster developed Behçet's disease (BD) with symptoms including orthostatic intolerance as an autonomic disorder. Multiple immune-suppressive therapies and a β-blocker successfully controlled both the disease activity of BD and the autonomic disorders. ⋯ Insufficient IL-10 production is reported in BD. The reactivation of VZV with this cytokine profile suggests that BD will develop with various symptoms, including severe autonomic disorders.

Hemophagocytic Lymphohistiocytosis in a Patient with Rheumatoid Arthritis on Pembrolizumab for Lung Adenocarcinoma.
Immune checkpoint inhibitors have changed the landscape of classic cancer treatment. However, their use is associated with the emergence of new adverse events. ⋯ He subsequently developed hemophagocytic lymphohistiocytosis (HLH), which is potentially fatal but has not been properly established as an immune checkpoint inhibition-induced event. We herein report the case of a patient with pembrolizumab-induced HLH.

Nivolumab, an antibody against human programmed cell death 1 (PD-1), enhances pre-existing immune responses and has antitumor activity. However, it may also cause undesirable immune-related adverse events (irAEs), such as anti-PD-1-related colitis. In addition, Nivolumab can worsen pre-existing autoimmune diseases. ⋯ Its exact cause is unknown, but it may involve the dysregulation of the mucosal immune response. Thus, it is of great interest whether nivolumab can affect UC activity. This is the first report of a patient with epipharyngeal carcinoma and ulcerative colitis who was confirmed to have been safely treated with nivolumab based on autopsy findings.

Aortic arch aneurysm (AAA) is a rare involvement in Behçet disease (BD). It is often life-threatening, yet few reports related to the treatment of AAA have been published. We herein report a 27-year-old woman with AAA caused by vascular BD. ⋯ However, the inflammation had not subsided after three weeks, so infliximab (IFX) was added for relief. After IFX administration, the C-reactive protein level normalized, and computed tomography at three months after therapeutic intervention revealed that the aneurysm had disappeared. This case suggests that early induction of IFX might be effective for aortic aneurysm in BD.

Hepatic encephalopathy (HE) is a significant symptom of decompensated liver cirrhosis. Occlusion of portosystemic shunts is used to treat refractory HE. Nevertheless, these treatments often cause adverse events, such as ascites and esophageal varices. ⋯ After SPDPS, there were no obvious complications, and the patient's ammonia level significantly decreased. To date, the patient has not experienced recurrent HE. SPDPS appears to be a safe and effective treatment method for portosystemic encephalopathy.
