[Relation between fetal intrauterine growth retardation and anticardiolipin antibodies]
Insights
Anticardiolipin antibodies (ACA) are linked to increased risk of intrauterine growth retardation (IUGR). Detecting ACA may aid in diagnosing and treating IUGR in pregnant individuals.
Area of Science:
- Obstetrics and Gynecology
- Immunology
- Perinatology
Context:
- Intrauterine growth retardation (IUGR) is a significant concern in prenatal care.
- Anticardiolipin antibodies (ACA) are autoantibodies associated with thrombotic events and pregnancy complications.
Purpose:
- To examine the association between anticardiolipin antibodies and fetal intrauterine growth retardation.
- To evaluate the diagnostic and therapeutic implications of ACA detection in IUGR.
Summary:
- A study of 5,330 normal pregnancies found a 2.70% positive rate for ACA.
- The incidence of IUGR was significantly higher (15.28%) in pregnancies with positive ACA compared to those with negative ACA (1.77%).
- Immunocomplex depositions were observed in placentas of IUGR cases with positive ACA.
Impact:
- Anticardiolipin antibodies are identified as a potential causative factor for IUGR.
- Serum ACA determination offers a novel approach for the diagnosis and management of IUGR.
- This research highlights the importance of immunological markers in understanding and addressing fetal growth restriction.
Objective:
To investigate the relationship between fetal intrauterine growth retardation and anticardiolipin antibodies.
Methods:
Serum anticardiolipin antibodies were detected with ELISA method in 5,330 cases of normal gravidas. Meanwhile, the observation of immunocomplex depositions in placentas in cases of positive anticardiolipin antibodies (ACA) were observed by immunofluorescence examination.
Results:
The positive ACA rate in normal gravidas was 2.70%. The incidence of intrauterine growth retardation (IUGR) was 15.28% in cases of positive ACA, whereas was 1.77% in cases of negative ACA. There were significant differences between two groups (P < 0.001). Among children born in mothers with positive ACA, there were 5 cases of positive ACA. Immunocomplex depositions (Immunoglobulins & Complements) were all found in placenta of IUGR.
Conclusions:
ACA could be one of causes of IUGR. Determination of serum ACA would offer a new clue to diagnosis and treatment of IUGR.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
