Antiphospholipid Syndrome

antiphospholipid syndrome apscauses symptoms and diagnosis

Antiphospholipid Syndrome (APS) is an autoimmune disorder that leads to abnormal blood clotting in arteries and veins, potentially causing serious health complications. It is essential to get an early diagnosis and proper management to prevent complications. If you are searching for "pathlabs near me" or a "diagnostic center near me" to get tested for APS, this guide will help you understand the causes, symptoms, and diagnostic methods.

Antiphospholipid Syndrome (APS) – Causes, Symptoms & Diagnosis Explained

What Is Antiphospholipid Syndrome (APS)?

Antiphospholipid Syndrome (APS), also called Hughes syndrome, is a chronic condition in which the body produces abnormal antibodies called antiphospholipid antibodies. These antibodies increase the risk of blood clots in arteries and veins.

What Are Phospholipids?

Phospholipids are fats that help make up cell membranes. In APS, the immune system targets these phospholipids, triggering clotting problems throughout the body.


Key Causes of APS

The exact cause of APS is not fully understood, but common triggers include:

? Autoimmune conditions like lupus
? Genetic predisposition
? Infections (viral or bacterial)
? Certain medications
? Idiopathic (unknown causes)

APS may occur independently or alongside other autoimmune diseases.


Major Symptoms of APS

APS affects blood flow and can lead to symptoms such as:

1. Blood Clot-Related Symptoms

  1. Deep Vein Thrombosis (DVT) – pain, swelling in legs

  2. Pulmonary Embolism – chest pain, shortness of breath

  3. Stroke symptoms – sudden weakness, slurred speech

2. Pregnancy-Related Complications

  1. Recurrent miscarriage

  2. Stillbirth

  3. Preeclampsia

3. Other Symptoms

  1. Headaches or migraines

  2. Skin changes (livedo reticularis)

  3. Low platelets (thrombocytopenia)

These symptoms vary depending on where clots form in the body.


How APS Is Diagnosed

Diagnosis of APS involves both clinical history and blood tests.

1. Blood Tests

Doctors check for antiphospholipid antibodies such as:

  1. Lupus anticoagulant (LA)

  2. Anticardiolipin antibodies (aCL)

  3. Anti-β2 glycoprotein I antibodies (anti-β2GPI)

These antibodies must be positive on two separate occasions at least 12 weeks apart for a confirmed diagnosis.


2. Clinical Criteria

APS diagnosis also considers:
? History of abnormal blood clots
? Pregnancy loss or complications
? Recurrent thrombosis

Doctors use established criteria to confirm APS.


How APS Affects the Body

APS increases the risk of dangerous clots, which can lead to:

Body system Possible APS effect
Brain Stroke, memory issues
Heart Heart attack, valve problems
Lungs Pulmonary embolism
Legs DVT
Pregnancy Miscarriage, preeclampsia

Prompt diagnosis and management are critical.


How APS Is Managed

APS is treated to prevent clots and complications:

? Anticoagulant medication (blood thinners like warfarin or DOACs)
? Low-dose aspirin in some cases
? Monitoring during pregnancy
? Lifestyle adjustments (no smoking, healthy weight)

Treatment varies based on individual risk and history.
