About this study
Official title: Pregnancy Outcomes Prior to a Systemic Lupus Erythematosus Diagnosis
This is an observational, monocentric, retrospective cohort study. Its primary objective is to examine maternal and foetal outcomes in pregnancies that occurred before the diagnosis of systemic lupus erythematosus (SLE) in a group of female participants who were subsequently diagnosed with the condition.
Read the detailed description
The investigators aim to study obstetrical and systemic signs in participants' pregnancies prior to an SLE diagnosis. Information will be collected from medical records and by asking participants questions during medical visits. The diagnosis of SLE is made using the ACR 1997 criteria. It is also based on renal histological findings.
The study must answer three questions:
- Are systemic signs of SLE present before or during pregnancy?
- What were the fetal and maternal outcomes after or during each pregnancy? What is/was the severity of SLE after diagnosis?
- Conditions
- Pregnancy Complications, SLE
- Being tested
- Collect data on all pregnancies before and after diagnosis of SLE.
- Keywords
- Pregnancy, SLE, Obstetrical events
- Medical subject headings
- Pregnancy Complications
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Collect data on all pregnancies before and after diagnosis of SLE.Other
For participants who are still alive, data are collected from interviews with patients using a prepared questionnaire that asks about all pregnancies and obstetrical events prior to the diagnosis of SLE.
For deceased patients, data are taken from the medical records of obstetrical events.
Data will be collected on anthropometric, biological, immunological, and histological features before and after the diagnosis of SLE, if available.
The activity and severity of the disease after diagnosis will be assessed using the recommended tools.
| Study group | Role | What they receive |
|---|---|---|
| Femelle patients at procreation age with diagnosis of LES | Patients that have had pregnancies history before the diagnosis of LES Receives: Other: Collect data on all pregnancies before and after diagnosis of SLE. |
What is being measured
The primary outcome is the main question the study is designed to answer.
1. Primary outcome: Prevalence of obstetrical events before the diagnosis of SLE. Secondary outcome: 1. Assess the severity of the disease at the time of LES diagnosis. 2. Compare the outcomes of pregnancies before and after the LES
- Evaluate the number of pregnancies for each woman before and after the diagnosis of lupus.
- Assess obstetric events for each pregnancy (spontaneous abortion, prematurity, fetal death, pre-eclampsia, HELLP syndrome, or other pregnancy-related events).
- Assess the presence of systemic signs during pregnancy or the postpartum period.
- Collect data on the baby's status, including weight, height, and any morbid conditions (dermatological, cardiac, respiratory, etc.).
- Note the timeframe between the last pregnancy or delivery and the SLE diagnosis.
Measured: The patient will be assessed from the beginning of each pregnancy and in the three month after childbirth
