This project is a multi-center, prospective, real-world cohort study that collects clinical data of Chinese patients with AQP4-positive NMOSD in the acute stage. It comprehensively assesses the clinical outcomes of the patients and aims to compare the clinical efficacy and safety of icoxib as a combined add-on treatment versus simple hormone shock therapy during the acute phase of NMOSD.Using simple hormone shock therapy (IVMP) as the control group, the efficacy and safety of etanercept treatment in the acute attack phase of Chinese patients with AQP4-positive neuromyelitis optica spectrum disorder (NMOSD) were evaluated.A teljes eredeti leírásKevesebb

Eculizumab Add-On Therapy in the Acute Phase of Neuromyelitis Optica Spectrum Disorder: A Multicenter Prospective Real-World Study

This project is a multi-center, prospective, real-world cohort study that collects clinical data of Chinese patients with AQP4-positive NMOSD in the acute stage. It comprehensively assesses the clinical outcomes of the patients and aims to compare the clinical efficacy and safety of icoxib as a combined add-on treatment versus simple hormone shock therapy during the acute phase of NMOSD.Using simple hormone shock therapy (IVMP) as the control group, the efficacy and safety of etanercept treatment in the acute attack phase of Chinese patients with AQP4-positive neuromyelitis optica spectrum disorder (NMOSD) were evaluated.

Bevonási feltételek: Age: 18 - 65 years old, gender not restricted; Patients who meet the diagnostic criteria for NMOSD as set by the International Panel for NMO Diagnosis (IPND) in 2015, and have positive serum AQP4-IgG (by CBA method or live cell method); Acute phase of NMOSD-ON, defined as new or worsening optic nerve dysfunction (visual acuity decline accompanied or not by eye pain and visual field defect), with an onset duration of ≤ 21 days, and clear evidence of new or recurrent optic nerve damage on imaging (new or expanded T2WI lesions, with enhancement); the best corrected visual acuity (BCVA) of the affected eye during the acute phase of NMOSD-ON (if both eyes are affected simultaneously, the worse eye is considered) drops from above 0.3 to ≤ 0.1; Acute phase of NMOSD-TM, defined as new or worsening spinal cord dysfunction (limb weakness or numbness, accompanied or not by urinary and defecation disorders), with an onset duration of ≤ 21 days, and clear evidence of new or recurrent spinal cord damage on imaging (new or expanded T2WI lesions, with enhancement); the EDSS score during the acute phase of NMOSD-TM increases from ≤ 4.0 to ≥ 6.0; Clinical onset and recurrence determination requires unanimous judgment by each center and the center committee (an independent group of 3 people); Agree to receive meningococcal vaccine or use eculizumab during and 2 weeks after the medication; Sign the informed consent.
