ABSTRACT
Anti-phospholipid syndrome (APS) nephropathy is an autoimmune disease that is sometimes accompanied by systemic lupus erythematosus (SLE). Here, we report the use of rituximab to treat a case of APS nephropathy in a SLE patient with recurrent vascular thrombosis. A 52-year-old woman, who had been diagnosed with SLE 11 years earlier, was referred to a nephrology clinic for evaluation of azotaemia and proteinuria. She had experienced spontaneous abortion at 35 years of age. The patient had been diagnosed with right popliteal thrombosis at 39 years of age, and with left pulmonary artery thrombosis and SLE at 41 years of age. Before admission, she was undergoing anticoagulant and immunosuppressive therapies, with follow-up in the rheumatology clinic. At her last outpatient clinic visit before admission, she exhibited mild bilateral lower-limb pitting oedema, impaired renal function and proteinuria. Renal biopsy revealed arteriolar wall thickening, with thrombi in the capillary lumina and marked inflammatory cell infiltration in the interstitium. The patient was treated with warfarin and high-dose corticosteroids. Intravenous rituximab (500 mg) was also administered twice at a 4-week interval. Her renal function did not worsen any further, and her proteinuria decreased. Here we report the successful use of rituximab to treat APS nephropathy in a patient with SLE, who had progressive renal insufficiency.
