Over a median duration of 39.5 months, 80 patients completed the entire follow-up, and 47.5% (38/80) patients exhibited monophasic course. A total of 36% (18/50) patients positively for anti-astrocyte antibodies had a monophasic course, which is significantly lower than patients negatively for anti-astrocyte antibodies (66.7%, 20/30) (<i>p</i> = 0.008). The presence of anti-astrocyte antibodies (hazard ratio (HR), 2.243; 95% CI, 1.087–4.627; <i>p</i> = 0.029) and ≥4 cerebrum lesions at first attack (HR, 2.494; 95% CI, 1.224–5.078; <i>p</i> = 0.012) were risk factors for disease relapse, while maintenance immunotherapy during remission (HR, 0.361; 95% CI, 0.150–0.869; <i>p</i> = 0.023) was protective factor.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Interpretation</h3>\u0000 \u0000 <p>Double negative atypical IDD are unique demyelinating diseases with a high relapse rate.
