Cohort Study on Neuroimmune Diseases in the Reproductive Age (RANID)

2026年6月13日 更新者：Wei Qiu、Third Affiliated Hospital, Sun Yat-Sen University
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.

Fetal Biometry Measurements: Biparietal Diameter, Head Circumference, Abdominal Circumference, and Femur Length
大体时间：Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
Standard fetal biometric parameters, including Biparietal Diameter (BPD), Head Circumference (HC), Abdominal Circumference (AC), and Femur Length (FL), are measured via prenatal ultrasound. These measurements (reported in millimeters) are used to monitor fetal growth and estimate gestational age. The values will be reported as Z-scores or percentiles for each trimester, and compared between groups.

Estimated Fetal Weight
大体时间：Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.

The estimated fetal weight (EFW) percentile for gestational age will be calculated and reported for each trimester, and compared between groups.
Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
Umbilical Artery Doppler Pulsatility Index
大体时间：Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
The Umbilical Artery Pulsatility Index (UA-PI) is measured via Doppler ultrasound as an indicator of placental vascular resistance. The value is a dimensionless ratio. Results will be reported as the mean PI value and/or the number of participants with abnormal (e.g., absent or reversed end-diastolic flow) Doppler findings in each group.
Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
Amniotic Fluid Volume Index
大体时间：Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
The amniotic fluid volume is assessed via ultrasound, typically measured as the Amniotic Fluid Index (AFI) in centimeters. The result will be reported as the AFI value for each trimester, and the number of participants with oligohydramnios (abnormally low fluid) or polyhydramnios (abnormally high fluid) will be documented and compared between groups.
Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
Number of Participants with Non-Reactive Non-Stress Test
大体时间：Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
In the third trimester, fetal well-being may be assessed by a Non-Stress Test (NST). The outcome is reported as the number and percentage of participants with a non-reactive NST, which may indicate potential fetal compromise, and compared between groups.
Assessed during the first trimester, second trimester, and third trimester of pregnancy. Up to 10 months.
Number of Participants with Pregnancy Loss
大体时间：Assessed at the time of delivery hospitalization.
The number and percentage of participants experiencing pregnancy loss, categorized as miscarriage (pregnancy loss at <20 weeks gestation) or stillbirth (fetal death at ≥20 weeks gestation). This outcome compares the rates of pregnancy loss between mothers with neuroimmune diseases and healthy controls.

Number of Neonates Admitted to the Neonatal Intensive Care Unit (NICU)
大体时间：Assessed from birth to hospital discharge, up to 1 month.
