Vasculite leucocytoclasique compliquée d'une atteinte rénale grave au décours d'une primo-infection à Parvovirus B19

The role of Parvovirus B19 has been suspected as an aetiological agent in many kinds of vasculitis, e.g. polyarteritis nodosa, Wegener's disease and leucocytoclastic vasculitis. In this case report, the detection of specific IgM and the absence of other factors associated with vasculitis are consistent with a causal role of Parvovirus B19. In previously published cases, the prognosis of parvovirus B19-associated vasculitis does not seem to differ from that of idiopathic vasculitis. To our knowledge, this is the first case exhibiting concomitant and persistent severe renal involvement.
