Preferable effect of CTLA4-Ig on both bone erosion and bone microarchitecture in rheumatoid arthritis revealed by HR-pQCT.

This exploratory study aimed to examine the impact of abatacept treatment on bone structure in patients with rheumatoid arthritis (RA) using high-resolution peripheral quantitative computed tomography (HR-pQCT). RA patients initiating either abatacept or newly introduced csDMARDs were enrolled in this prospective, non-randomized, two-group study. Bone structure in the 2nd and 3rd metacarpal heads was assessed using HR-pQCT at 0, 6, and 12 months after enrollment.

Predictive Value of Magnetic Resonance Imaging-detected Tenosynovitis of the Metacarpophalangeal and Wrist Joints for the Development of Rheumatoid Arthritis among Patients with Undifferentiated Arthritis.

Objective The early diagnosis of rheumatoid arthritis (RA) improves disease outcomes. Using bilateral magnetic resonance imaging (MRI), we investigated whether or not tenosynovitis at the level of the metacarpophalangeal (MCP) and wrist joints, as well as non-symmetrical versus symmetrical involvement, predicts RA development in undifferentiated arthritis (UA) patients. Methods We collected the clinical and serological findings as well as bilateral gadolinium-enhanced 1.

Narcolepsy-like symptoms triggered by lemborexant in the context of hyperactive delirium in a patient with bipolar depression: a case report.

Unlabelled: Lemborexant is a dual orexin antagonist and is considered a safe and effective hypnotic. Dual orexin antagonists induce physiological sleep by blocking orexin receptors. Although the blockade of orexin signaling has triggered narcolepsy-like symptoms in rodents, there is currently no evidence of lemborexant inducing narcolepsy-like symptoms in humans.

Successful rechallenge with paliperidone after clozapine treatment for a patient with dopamine supersensitivity psychosis.

We describe the case of a 49-year-old Japanese male patient successfully treated with a paliperidone rechallenge following 2-year treatment with clozapine for treatment-resistant schizophrenia. He had responded well to conventional antipsychotic treatment for the initial psychotic episode but gradually developed dopamine supersensitivity; even treatment with paliperidone and another antipsychotic medication (a total up to 1700 mg in chlorpromazine-equivalent dose) had not improved his psychotic symptoms. Clozapine treatment produced temporary symptomatic relief, but the clozapine dose could not be increased to > 150 mg due to the patient's intolerance.
