Abstract
Hypocomplementemic urticarial vasculitis is a rare systemic vasculitis, affecting small vessels, characterised by chronicle urticaria, hypocomplementemia, and systemic manifestations. Renal involvement, whose prevalence varies between 9% and 60%, is mainly glomerular. We here report the case of a 59 years old woman presenting kidney failure, associated with chronicle urticaria and arthralgias. Laboratory investigation showed haematuria, proteinuria, hypocomplementemia and anti-SSa antibody positivity. A percutaneous kidney biopsy revealed focal and segmental glomerulonephritis associated with an acute interstitial nephritis. Hypocomplementemic urticarial vasculitis diagnosis was established after identifying anti-C1q antibodies. The lack of a dry syndrome, the negativity of a Schirmer test and the lack of sialadenitis on a salivary gland biopsy excluded an associated Gougerot-Sjögren Syndrome. The patient was treated with hydroxychloroquine and low-dose steroids, enabling a clinical and biological recovery. Of the 82 cases in the literature describing hypocomplementemic urticarial vasculitis associated nephropathies, 72 (88%) were a glomerular impairment, most frequently secondary to membranoproliferative glomerulon...
