What is Antiphospholipid Antibody Syndrome?

Antiphospholipid antibody syndrome (APS) is an autoimmune thrombophilic disorder characterized by persistent antiphospholipid antibodies accompanied by specific clinical manifestations, primarily venous or arterial thrombosis and pregnancy-related complications. This condition creates a hypercoagulable state where the immune system mistakenly produces antibodies that attack phospholipid-binding proteins, increasing the risk of abnormal blood clot formation throughout the circulatory system.

APS exists in two primary forms: primary APS occurs independently, while secondary APS develops in association with other autoimmune conditions, particularly systemic lupus erythematosus (SLE). The syndrome represents one of the most common acquired thrombophilias and affects multiple organ systems through thrombotic microangiopathy and inflammatory mechanisms.

Key clinical features of APS:

• Vascular thrombosis in any tissue or organ
• Recurrent pregnancy loss, especially in second and third trimesters
• Thrombocytopenia and hemolytic anemia
• Neurological manifestations including strokes and cognitive dysfunction
• Cardiac valvular abnormalities and vegetation
• Livedo reticularis and other dermatological findings

How Does Antiphospholipid Syndrome Cause Blood Clots?

The thrombogenic mechanisms in antiphospholipid syndrome involve multiple interconnected pathways that disrupt the normal balance between procoagulant and anticoagulant systems. Antiphospholipid antibodies target phospholipid-binding plasma proteins rather than the phospholipids themselves, primarily focusing on β₂-glycoprotein I (β₂GPI) and prothrombin.

These autoantibodies initiate thrombosis through several mechanisms:

• Interference with natural anticoagulant pathways, particularly protein C and protein S systems
• Disruption of annexin A5, a natural anticoagulant protein that forms protective shields on phospholipid surfaces
• Activation of endothelial cells leading to increased adhesion molecule expression and proinflammatory cytokine production
• Platelet activation and enhanced thrombin generation
• Complement system activation and neutrophil extracellular trap formation
• Impairment of fibrinolytic system function

The result is a profound prothrombotic state that can manifest as venous thromboembolism, arterial thrombosis, or small vessel occlusion affecting virtually any organ system. The specific clinical presentation depends on the vessel type, size, and location affected by the thrombotic process.

What Are the Different Types of Antiphospholipid Antibodies?

Laboratory diagnosis of APS relies on detecting three main classes of antiphospholipid antibodies that have been standardized and validated through international efforts. These antibodies serve as serological markers for the syndrome and contribute differently to the thrombotic risk profile.

The internationally recognized antiphospholipid antibody tests include:

Lupus Anticoagulant (LA)
LA represents a functional assay that detects antibodies that prolong phospholipid-dependent coagulation tests in vitro. Despite its name, LA is strongly associated with thrombotic risk rather than bleeding tendency. Testing involves a multi-step process including screening, mixing, and confirmation procedures using activated partial thromboplastin time (aPTT), dilute Russell’s viper venom time (dRVVT), and other phospholipid-dependent assays.

Anticardiolipin Antibodies (aCL)
These antibodies target cardiolipin, a phospholipid component of mitochondrial membranes, and are detected using standardized enzyme-linked immunosorbent assays (ELISA). Testing measures both IgG and IgM isotypes, with medium to high titers (typically >40 GPL or MPL units) having greater clinical significance than low positive results.

Anti-β₂-Glycoprotein I Antibodies (aβ₂GPI)
These antibodies directly target β₂GPI, a plasma protein that binds negatively charged phospholipids and serves as the primary antigenic target in APS. Like aCL, aβ₂GPI antibodies are detected via ELISA for IgG and IgM isotypes, with higher titers conferring increased thrombotic risk.

Additional autoantibodies being investigated for their potential clinical relevance include antibodies against phosphatidylserine, prothrombin, annexin A5, and domain I of β₂GPI, though these are not yet included in formal classification criteria.

What Are the Common Symptoms of Antiphospholipid Antibody Syndrome?

APS manifests through diverse clinical presentations that reflect the widespread nature of thrombotic events across different organ systems. Symptom recognition is crucial for timely diagnosis and intervention, particularly in high-risk situations.

Thrombotic manifestations:

• Deep vein thrombosis (DVT) with leg swelling, pain, and erythema
• Pulmonary embolism causing chest pain, dyspnea, and hemoptysis
• Arterial thrombosis leading to stroke, transient ischemic attack, or acute limb ischemia
• Renal thrombosis causing hypertension and renal impairment
• Adrenal hemorrhage or thrombosis resulting in adrenal insufficiency
• Retinal vessel occlusion causing visual disturbances or loss

Obstetric manifestations:

• Recurrent early pregnancy loss (before 10 weeks gestation)
• Unexplained fetal death beyond 10 weeks gestation
• Severe preeclampsia, eclampsia, or HELLP syndrome
• Placental insufficiency leading to intrauterine growth restriction
• Severe preterm delivery due to placental complications

Hematological manifestations:

• Thrombocytopenia (usually mild to moderate)
• Coombs-positive hemolytic anemia
• Evans syndrome (combined thrombocytopenia and hemolysis)

Neurological manifestations:

• Transient global amnesia or mild cognitive dysfunction

How is Antiphospholipid Syndrome Diagnosed?

The diagnosis of APS requires fulfillment of both clinical and laboratory criteria based on the internationally accepted Sydney Classification Criteria. Diagnosis necessitates the presence of at least one clinical criterion and one laboratory criterion, with persistence of antibodies confirmed over time.

Clinical criteria components:

• Vascular thrombosis: One or more objectively confirmed episodes of arterial, venous, or small vessel thrombosis in any tissue or organ
• Pregnancy morbidity:
  • One or more unexplained deaths of morphologically normal fetuses at or beyond 10 weeks gestation
  • One or more premature births of morphologically normal neonates before 34 weeks due to severe preeclampsia, eclampsia, or placental insufficiency
  • Three or more unexplained consecutive spontaneous abortions before 10 weeks gestation

Laboratory criteria components:

• Lupus anticoagulant present in plasma on two or more occasions at least 12 weeks apart
• Anticardiolipin antibody of IgG and/or IgM isotype in medium or high titer on two or more occasions at least 12 weeks apart
• Anti-β₂-glycoprotein I antibody of IgG and/or IgM isotype in titer >99th percentile on two or more occasions at least 12 weeks apart

Comprehensive diagnostic evaluation includes:

• Detailed personal and family history of thrombosis and pregnancy complications
• Physical examination focusing on skin, neurological, and cardiovascular systems
• Laboratory confirmation of antiphospholipid antibodies according to international standards
• Imaging studies to document thrombotic events when clinically indicated
• Exclusion of other thrombophilic disorders through appropriate testing

FAQs: Frequently Asked Questions About Antiphospholipid Antibody Syndrome

Can antiphospholipid syndrome be cured?
Currently, there is no cure for antiphospholipid syndrome, but the condition can be effectively managed with appropriate anticoagulant therapy and lifestyle modifications. Treatment focuses on preventing thrombotic events and managing complications. Many patients with well-controlled APS maintain excellent quality of life and normal life expectancy with proper medical care and monitoring through services like Doseway’s online doctor consultation.

What is the life expectancy for someone with APS?
With proper treatment and adherence to anticoagulant therapy, most APS patients have normal life expectancy. However, those with recurrent thrombotic events, particularly arterial thrombosis, or catastrophic APS may have reduced survival. Early diagnosis, consistent treatment, and regular monitoring significantly improve long-term outcomes and quality of life.

Can I get pregnant if I have antiphospholipid syndrome?
Yes, successful pregnancy is possible with APS under careful management that typically includes low-dose aspirin and heparin injections. Specialized obstetric care with maternal-fetal medicine specialists is essential, as pregnancy requires close monitoring and medication adjustments. Doseway offers lab tests at home and medication delivery to support APS patients throughout pregnancy.

What is the difference between APS and lupus?
APS is an autoimmune disorder focused specifically on blood clotting mechanisms, while systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that can affect various organs. APS can occur independently (primary APS) or in conjunction with SLE (secondary APS). Approximately 30-40% of SLE patients have antiphospholipid antibodies, and about half of these will develop clinical APS.

Are there dietary restrictions for APS patients?
APS patients on warfarin should maintain consistent vitamin K intake rather than completely avoiding vitamin K-rich foods. Otherwise, an anti-inflammatory Mediterranean-style diet is generally recommended. Alcohol should be consumed in moderation, if at all, and particularly limited when combined with certain medications. Consultation with a nutritionist through Doseway’s health services can provide personalized dietary guidance.

Can children develop antiphospholipid syndrome?
Yes, pediatric APS does occur, though it is less common than in adults. Presentation in children may differ somewhat, with arterial thrombosis relatively more common than in adults. Diagnosis and management principles are similar, though medication dosing requires pediatric adjustment. Both primary and secondary forms can occur in children.

How does COVID-19 affect APS patients?
COVID-19 infection may increase thrombotic risk in APS patients due to the prothrombotic state associated with severe infection. Some studies suggest possible induction or worsening of antiphospholipid antibodies following COVID-19. APS patients should maintain strict precautions against infection and seek prompt medical attention if symptoms develop. Vaccination is generally recommended with individual risk-benefit assessment.
