Brief Clinical Note

A case of total hip arthroplasty for femoral head necrosis while using satralizumab for neuromyelitis optica spectrum disorders

A 47-year-old woman developed right femoral head necrosis during long-term steroid use for neuromyelitis optica spectrum disorder. She underwent a total hip arthroplasty because her right hip pain persisted after satralizumab treatment. There were no postoperative infections. Under oral administration of tacrolimus 3 mg, prednisolone 11 mg, and acetaminophen 2,275 mg, her postoperative body temperature was less than 38°C and normalized in about 2 days after the operation. No parameters indicating worsening of inflammation were observed in the blood test. In satralizumab-treated patients, infection cannot be ruled out even without inflammatory findings. In particular, if a slight fever of the 37°C-range or a mildly high white blood cell count persists, paying attention to signs of infection and actively investigating the presence or absence of infection using medical image diagnostic devices are necessary.
