title: [McDuffie hypocomplementemic urticarial vasculitis associated with Sjögren's syndrome].
abstract: We report a patient with Sjögren's syndrome who presented with urticarial hypocomplementemic vasculitis. A 46-year-old female was admitted for assessment of ascitis. Clinical examination and computed tomographic scan disclosed evidence of multiple peripheral and intra abdominal lymph nodes. During her admission, she developed several bouts of acute angioedema and urticarial skin lesions. Minor salivary gland biopsy showed focal sialadenitis, stage IV of Chisholm. Schirmer's test was positive. Laboratory examination found low levels of C1q and high levels of C1q antibodies. Therapy with prednisone and hydroxychloroquine was initiated. Six months later, the patient presented with lower limb oedema. Urinalysis showed proteinuria (1g/day) and renal biopsy revealed membranous nephropathy with favorable outcome with corticosteroids.
