We herein report a patient with rheumatoid arthritis (RA) who successfully delivered a healthy child with continuous administration of sarilumab throughout pregnancy. She delivered her first child, a healthy boy, following in vitro fertilization-embryo transfer (IVF-ET) while using etanercept and low-dose prednisolone. Disease activity persisted after delivery, so etanercept was switched to sarilumab. ⋯ She delivered a healthy girl at the 38th week of gestation by Caesarean section. No abnormalities were detected at or within 6 months after birth. Sarilumab was safe and effective in this pregnant woman with RA.

The coexistence of multiple autoantibodies associated with autoimmune encephalitis (AE) is rare. A 63-year-old woman developed psychosis and consciousness disorder. Her cerebrospinal fluid was positive for anti-N-methyl-D-aspartate receptor antibodies, and her serum was positive for anti-Hu antibodies. ⋯ AE complicated with small-cell lung cancer was diagnosed. Immunotherapy (steroid therapy and intravenous immunoglobulin) and four courses of carboplatin-etoposide chemotherapy were required to improve her neurological symptoms. When the coexistence of multiple antibodies is detected, despite its rarity, aggressive detection and treatment of any underlying malignancy may be recommended.

We herein report a 49-year-old Japanese man with relapsing polychondritis (RP) and aseptic meningoencephalitis. Four years ago, the patient was diagnosed with RP. Prednisolone (PSL) was started at 30 mg/day, and the symptoms promptly disappeared. ⋯ Intravenous cyclophosphamide was combined with PSL. After treatment, the patient's cognitive impairment clearly improved. In conclusion, RP rarely causes aseptic meningoencephalitis, highlighting the need for prompt and aggressive immunosuppressive therapy.
