A man who was an inactive hepatitis B virus (HBV) carrier with positive hepatitis B surface antigen (HBs antigen) and undetectable HBV-DNA under anti-viral treatment developed nephrotic syndrome at 52 years old, and a renal biopsy revealed advanced membranous nephropathy (MN) with focal cellular crescents, interstitial hemorrhaging, and peritubular capillaritis. Immunofluorescence studies demonstrated granular IgG deposition and HBs antigen-positivity along the capillaries. ⋯ We considered MN combined with small-vessel vasculitis due to HBV infection. These results suggest that HBV-related kidney disease should be considered even in patients with an inactive HBV carrier status under treatment.

In November 2019, a 76-year-old woman was diagnosed with limited cutaneous scleroderma caused by Raynaud's phenomenon and skin hardening on the periphery of the extremities. In October 2022, blood tests and abdominal ultrasonography revealed liver dysfunction and multiple liver masses, respectively. ⋯ Considering her age, the patient was ineligible for liver transplantation, and she died in September 2023. Peliosis hepatis complicated by scleroderma has not been previously reported, so we report this as a valuable case.

Observational Study
Daily Glucose Profiles after Switching from Injectable to Oral Semaglutide in Patients with Type 2 Diabetes Mellitus.
Objective This prospective observational study explored the changes in the daily glycemic profile after switching from injectable to oral semaglutide in patients with type 2 diabetes mellitus. Methods Patients with type 2 diabetes mellitus who were treated with once-weekly 0.5 mg injectable semaglutide and wished to switch to once-daily oral semaglutide participated in this study. Oral semaglutide was initiated at 3 mg and increased to 7 mg a month later, according to the package insert. ⋯ After trying oral semaglutide, 48% of patients responded that they preferred the oral formulation, while 35% preferred the injectable formulation, and 17% had no preference. Conclusion The mean glucose levels increased by 9 mg/dL on average after switching from once-weekly 0.5 mg injectable semaglutide to once-daily 7 mg oral semaglutide, with an increased inter-individual variability. The change in treatment satisfaction considerably varied among patients.

Antineutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis (AAV) predominantly affects small vessels. Almost all AAV patients are positive for myeloperoxidase- or proteinase 3-ANCA, and ANCA plays a crucial role in the pathogenesis of AAV. ⋯ ANCA-negative AAV is a rare clinical entity that is difficult to diagnose, and pleuritis and digital ischemia are rare manifestations of AAV. An early diagnosis and appropriate treatment are important, as any delay in the diagnosis may worsen the prognosis.

Anti-melanoma differentiation-associated gene 5 (MDA5) antibody-positive clinically amyopathic dermatomyositis (CADM) is a subtype of dermatomyositis without severe myositis but with characteristic cutaneous manifestations and severe interstitial lung disease. Joint symptoms can occur in patients with anti-MDA5 antibody-positive CADM. However, the treatment strategy and utility of ultrasound for treating joint symptoms remain unknown. We herein report an 85-year-old man with anti-MDA5 antibody-positive CADM who presented with ultrasound-confirmed synovitis that improved with medium-dose corticosteroid therapy.
