Anti-neutrophil cytoplasmic antibody vasculitis presenting with bilateral renal vein thrombosis

چکیده
We report a case of anti-neutrophil cytoplasmic antibody (ANCA)-associated necrotizing crescentic glomerulonephritis presenting with bilateral renal vein thrombosis and pulmonary emboli in a patient who also had a lupus anticoagulant and anti-cardiolipin antibodies. Although the link between venous thrombosis and ANCA vasculitis is well established, the coexistence of renal vein thrombosis is unusual. Furthermore, despite the positive ANCA, he was initially negative for antibodies to myeloperoxidase (MPO) and proteinase-3 (PR3), illustrating that a positive ANCA may be significant despite a negative test for antibodies to MPO and PR3.

UNLABELLED INTRODUCTION Anti-neutrophil cytoplasmic antibody-associated vasculitis has been associated with many drugs and it is a relatively rare side effect of the antihypertensive drug hydralazine. The diagnosis and management of patients who have anti-neutrophil cytoplasmic antibody-associated vasculitis may be challenging because of its relative infrequency, variability of clinical expr...

Background Eosinophilic granulomatosis with polyangiitis (EGPA) is an antineutrophil cytoplasmic antibody- (ANCA-) associated small vessel vasculitis with multisystem involvement. It is characterized with asthma, eosinophilia, and renal and peripheral nervous system involvement. However, EGPA presenting with bullous skin eruption is an uncommon dermatological manifestation. We report a rare cas...
متن کاملA Case of Membranous Glomerulonephritis with Superimposed Anti-Neutrophil Cytoplasmic Antibody-Associated Rapidly Progressive Crescentic Glomerulonephritis
Idiopathic membranous glomerulonephritis (IMGN) is commonly diagnosed in adults with proteinuria. Rapid deterioration of renal function is a rare complication of IMGN, except when accompanied by renal vein thrombosis, malignant hypertension, or other underlying disease, including lupus nephritis. Here, we present a case of rapid deterioration of renal function in a patient with MGN superimposed...

A 75-year-old African American woman with history of high blood pressure on hydralazine for 3 years presented with acute onset of shortness of breath and hemoptysis. Lab workup revealed a severe normocytic anemia and a serum creatinine of 5.09 mg/dL (baseline 0.9). Bronchoscopy demonst...
