Summary
Plasma C3d levels, indicating complement activation, showed no significant difference between pregnant and non-pregnant women. This finding is crucial for understanding complement activity in systemic lupus erythematosus (SLE) during pregnancy.
Area of Science:
- Immunology
- Clinical Chemistry
Background:
- Plasma C3d levels reflect complement system activation.
- Previous reports suggested altered C3d levels during pregnancy.
- Systemic lupus erythematosus (SLE) disease activity can be monitored using complement activation markers.
Purpose of the Study:
- To investigate plasma C3d levels in normal pregnancies.
- To compare C3d levels between pregnant and non-pregnant individuals.
- To assess the relevance of C3d as a marker in SLE irrespective of pregnancy status.
Main Methods:
- Measurement of plasma C3d degradation products.
- Comparison of C3d levels in 65 normal pregnancies versus non-pregnant controls.
Main Results:
- No statistically significant difference in plasma C3d levels was observed between pregnant and non-pregnant women.
- The findings contradict some previous reports on C3d levels during gestation.
Conclusions:
- Plasma C3d levels do not significantly change during normal pregnancy.
- C3d can serve as a reliable indicator of complement activation and SLE disease activity, independent of pregnancy.
