The extent of rare side effects of mRNA vaccines for coronavirus disease 2019 (COVID-19) remains unclear. Several cases of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) following COVID-19 vaccination have been reported. We herein report a 72-year-old man who presented with a fever after receiving the second dose of the Pfizer-BioNTech COVID-19 vaccine. He was diagnosed with acute kidney injury due to myeloperoxidase-ANCA-associated vasculitis and was treated with intermittent hemodialysis, high-dose prednisolone, and intravenous rituximab. His general symptoms and renal impairment subsequently improved. When systemic symptoms are prolonged or renal abnormalities appear after COVID-19 vaccination, the possibility of AAV should be considered.

Turmeric products have many useful physiological functions and are widely used as health food and food ingredient. Here, we report the use of HPLC-ESI-MS/MS to simultaneously quantify bisacurone and three curcuminoids (curcumin, demethoxycurcumin, and bisdemethoxycurcumin) in turmeric products (high viscosity liquid, granular powder, tablet, and solution). The results showed that the standard values and measured values of curcumin in each product were almost same. Demethoxycurcumin and bisdemethoxycurcumin were contained in each products. Meanwhile, the content of bisacurone differed greatly among the products. In particular, the highest amount of bisacurone was found in the turmeric product A (high viscosity liquid, 9.48 g/100 g product). It would become important to consider the bisacurone content in turmeric products.
