Summary
Pregnancy in women with lupus nephritis (LN) carries risks, especially with active disease. Stable LN offers a more favorable outlook, but vigilant maternal and fetal monitoring is crucial for all pregnant individuals with LN.
Area of Science:
- Nephrology
- Obstetrics
- Rheumatology
Background:
- Pre-existing lupus nephritis (LN) poses significant risks during pregnancy.
- Outcomes vary based on disease activity at conception.
Purpose of the Study:
- To analyze maternal and fetal outcomes in pregnancies complicated by pre-existing lupus nephritis.
- To identify risk factors associated with poor fetal outcomes in this patient population.
Main Methods:
- Retrospective analysis of 55 pregnancies in 24 patients with pre-existing lupus nephritis.
- Patients were categorized into two groups: quiescent LN (Group A) and active LN (Group B) at conception.
Main Results:
- Group A (quiescent LN) had 36 pregnancies with a lower rate of complications compared to Group B.
- Group B (active LN) experienced higher rates of spontaneous abortions, intrauterine growth retardation (IUGR), hypertension, stillbirths, and maternal mortality.
- Overall fetal loss was 38.2% and perinatal mortality (PNM) was 150/1,000 deliveries.
Conclusions:
- Pregnant women with long-standing LN face high risks of spontaneous abortion and increased perinatal mortality.
- Pregnancy outcomes are relatively favorable for patients with stable LN at conception.
- Active lupus nephropathy, particularly with co-existing hypertension, significantly increases obstetric complications and maternal mortality risk.
- Intensive maternal and fetal surveillance is essential for pregnant women with LN to optimize pregnancy outcomes.
