Pregnancy complicated by the antiphospholipid syndrome

Area of Science:

• Obstetrics and Gynecology
• Rheumatology
• Hematology

Background:

• Antiphospholipid syndrome (APS) is an autoimmune disorder associated with an increased risk of thrombosis.
• Pregnancy in patients with APS is high-risk, with potential complications including preeclampsia, intrauterine growth restriction, and fetal distress.
• A history of unexplained venous thrombosis can be an indicator of underlying APS.

Purpose of the Study:

• To highlight the presentation of atypical severe preeclampsia in a patient with previously undiagnosed antiphospholipid syndrome (APS).
• To discuss the management of pregnancy complications in APS, including the role of thromboprophylaxis.
• To emphasize the importance of early diagnosis and appropriate management strategies for APS during pregnancy.

Main Methods:

• Case report of a patient with APS presenting with severe preeclampsia at 31 weeks' gestation.
• Review of current evidence regarding the use of low-dose heparin and aspirin for thromboprophylaxis in APS during pregnancy.
• Discussion of potential therapeutic options such as human immunoglobulin for selected cases.

Main Results:

• The patient developed severe preeclampsia, intrauterine growth retardation, thrombocytopenia, and fetal distress, necessitating urgent delivery.
• Postoperative thromboprophylaxis with low-dose heparin was initiated, and no postpartum complications occurred.
• Evidence suggests antepartum prophylaxis with low-dose heparin is beneficial in APS patients.

Conclusions:

• Early diagnosis of APS is critical for effective management during pregnancy.
• Antepartum prophylaxis with low-dose heparin is supported by recent evidence for patients with APS.
• The roles of low-dose aspirin and human immunoglobulin in managing APS during pregnancy require further investigation.
