Further Outpatient Care
Carefully monitor medication doses and the INR if applicable.
Closely observe the patient for clinical events.
Ensure the care of any underlying connective-tissue disease.
Further Inpatient Care
Intensive observation is warranted for patients with CAPS.
Inpatient & Outpatient Medications
The suggested medications include heparin, warfarin, aspirin, and, in selected cases, hydroxychloroquine, intravenous immunoglobulin, and corticosteroids.
Corticosteroids are rarely used for the treatment of recurrent fetal loss because of the increased risk of maternal morbidity. Generally, the use of corticosteroids is reserved for specific nonthrombotic manifestations, such as associated thrombocytopenia, autoimmune hemolytic anemia, or the treatment of an underlying connective-tissue disease.
Prescribe antihypertensive drugs when necessary.
Administer antihyperlipidemic agents including statins when appropriate.
When treating seriously ill patients with CAPS, transfer the patient to a setting where plasma exchange can be performed or where intravenous immunoglobulin or cyclophosphamide can be administered if needed.
Instruct the patient to avoid smoking.
Inform the patient to avoid oral contraceptives or estrogen replacement therapy.
Ensure that the patient avoids any prolonged immobilization.
Permanent functional disability or death can occur at a relatively young age. Complications may include the following:
- Cerebrovascular accident
- Pulmonary hypertension
- Renal failure
With appropriate medication and lifestyle modifications, most individuals with primary antiphospholipid syndrome (APS) lead normal healthy lives. However, subsets of patients continue to have thrombotic events despite aggressive therapies. In these patients and in patients with CAPS, the disease course can be devastating, often leading to significant morbidity or early death.
In large European cohort studies, 10-year survival is approximately 90-94%.
A retrospective study suggested that hypertension or medium-to-high titers of IgG anticardiolipin antibody are risk factors for a first thrombotic event in asymptomatic patients with antiphospholipid (aPL) antibodies. Primary prophylaxis against thrombosis appears to offer significant protection in such cases. Annual incidence of first thrombosis is approximately 0-5% in patients with a positive aPL test without previous thrombosis.
Patients with secondary APS carry a prognosis similar to that of patients with primary APS; in the former, however, morbidity and mortality may also be influenced by these patients' underlying autoimmune or rheumatic condition. In patients with SLE and APS, aPL antibodies have been associated with neuropsychiatric disease and have been recognized as a major predictor of irreversible organ damage.
Women with aPL antibodies who experience recurrent miscarriages may have favorable prognoses in subsequent pregnancies if treated with aspirin and heparin.
Stress the importance of early recognition of a possible clinical event.
Educate the patient about anticoagulation therapy.
Discuss the importance of planned pregnancies so that long-term warfarin can be switched to aspirin and heparin before pregnancy is attempted.
Stress the importance of minimizing modifiable risk factors in primary prevention of aPL-positive patients with no history of thrombosis.
