A Case of Multiple Venous Thrombosis as the First Manifestation of Lupus Nephritis

Kidney involvement in systemic lupus erythematosus (SLE) is common. The incidence of venous thrombosis in SLE ranges from 5-15%, and venous thrombosis in lupus nephritis associated with nephritic syndrome or antiphospholipid antibody syndrome is reported in 30-35%. Lupus nephritis with nephrotic syndrome is not infrequently encountered at the point of diagnosis of SLE, but venous thrombosis as the first manifestation of SLE is rare. Herein we present our clinical experience with a case of multiple venous thrombosis with nephrotic-range proteinuria as the first manifestation of lupus nephritis.
