Insights
Antiphospholipid syndrome (APS) in pregnancy increases risks for preeclampsia and preterm birth. Hydroxychloroquine and vitamin D show promise as additional treatments beyond standard care.
Area of Science:
- Obstetrics and Gynecology
- Immunology
- Rheumatology
Background:
- Antiphospholipid syndrome (APS) involves thrombosis and pregnancy complications due to antiphospholipid antibodies (aPLs).
- Early onset preeclampsia (<34 weeks) is a clinical criterion for APS, sharing pathophysiology with defective trophoblast invasion.
- Women with APS face increased risks of prematurity, often linked to placental dysfunction like preeclampsia or fetal growth restriction (FGR).
Purpose of the Study:
- To review the association between Antiphospholipid Syndrome (APS) and pregnancy complications.
- To discuss current and potential therapeutic strategies for APS in pregnancy.
- To highlight the role of hydroxychloroquine (HCQ), vitamin D, and curcumin in managing APS during gestation.
Main Methods:
- Literature review on Antiphospholipid Syndrome (APS) and pregnancy outcomes.
- Analysis of the pathophysiology linking APS and preeclampsia.
- Evaluation of existing and emerging treatments for APS in pregnant individuals.
Main Results:
- Preeclampsia complicates 10-17% of APS pregnancies; early onset is a diagnostic criterion.
- Women with APS have higher rates of preterm delivery, even without preeclampsia or FGR.
- Standard treatment (aspirin, heparin) is insufficient for 20-30% of patients, necessitating further interventions.
Conclusions:
- Hydroxychloroquine (HCQ) is an effective additional treatment for APS in pregnancy.
- Nutritional interventions like vitamin D show promise for improving outcomes.
- Curcumin's antioxidant and anti-inflammatory properties suggest potential as an adjunctive therapy for APS during pregnancy.
Abstract:
Antiphospholipid syndrome (APS) is characterized by venous or arterial thrombosis and/or adverse pregnancy outcome in the presence of persistent laboratory evidence of antiphospholipid antibodies (aPLs). Preeclampsia complicates about 10-17% of pregnancies with APS. However, only early onset preeclampsia (<34 weeks of gestation) belongs to the clinical criteria of APS. The similarities in the pathophysiology of early onset preeclampsia and APS emphasize an association of these two syndromes. Overall, both are the result of a defective trophoblast invasion and decidual transformation at early gestation. Women with APS are at increased risk for prematurity; the reasons are mostly iatrogenic due to placental dysfunction, such as preeclampsia or FGR. Interestingly, women with APS have also an increased risk for preterm delivery, even in the absence of FGR and preeclampsia, and therefore it is not indicated but spontaneous. The basic treatment of APS in pregnancy is low-dose aspirin and low-molecular-weight heparin. Nevertheless, up to 20-30% of women develop complications at early and late gestation, despite basic treatment. Several additional treatment options have been proposed, with hydroxychloroquine (HCQ) being one of the most efficient. Additionally, nutritional interventions, such as intake of vitamin D, have shown promising beneficial effects. Curcumin, due to its antioxidant and anti-inflammatory properties, might be considered as an additional intervention as well.
