Cohort Study on Neuroimmune Diseases in the Reproductive Age

Обзор

Neuroimmune diseases are more prevalent among women of reproductive age. Studies have shown that neuroimmune diseases may impact fertility. Therefore, effective management of neuroimmune diseases during pregnancy is particularly important. This study included a follow-up period of up to five years in patients with pregnancy-associated neuroimmune disorders. Data collected included relapse frequency, symptomatology, imaging findings, treatment regimens, peripheral blood profiles, EDSS scores, and MRI results. In addition, maternal drug concentrations, postpartum relapse rates, and neonatal development were monitored after delivery. Following the successful completion of the five-year follow-up, the research team plans to continue the prospective epidemiological study with ten-year follow-up phases. The aim of this study is to generate detailed clinical data on pregnancy-associated autoimmune diseases and to equip clinicians with evidence-based strategies for optimizing disease management during the reproductive age.
