Abstract:
Objective:To improve the understanding of the relationship between antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE).Methods:The clinical characteristics and process of diagnosis and treatment of a case was reported and analyzed. This patient was initially diagnosed as antiphospholipid syndrome and later developed new skin lesion and positive anti-dsDNA antibody, which made the diagnosis of systemic lupus erythematosus.Results:A 15-year-old girl suffered acute pulmonary embolism, lower extremity deep vein thrombosis, and high titer of anti-phospholipid antibody, but negative for other autoantibodies. So primary antiphospholipid syndrome was diagnosed. Symptoms were improved after thrombolysis and anticoa-gulation treatment. During the follow-up period, the patient developed malar erythema, lymphocytopenia, proteinuria, positive ANA, anti-dsDNA antibody, and reduced complement level. So she was diagnosed with systemic lupus erythematosus. After glucocorticoid pulse therapy and immunosuppressants treatment, the symptoms were relieved and lupus disease activity was decreased.Conclusion:A few primary APS patients can progress into SLE. Patients with risk factors such as a younger age of onset, positive ANA and positive Coomb's test results should be closely followed up.
