We report a case of biopsy-proven polyarteritis nodosa (classic type)
in association with the antiphospholipid syndrome. Medium-sized arteri
opathy was confirmed on visceral angiography. Elevated anticardiolipin
antibodies were detected before initiating therapy with methylprednis
olone and IV pulse cyclophosphamide. Rapid subsidence of symptoms corr
elated with a gradual normalisation of the erythrocyte sedimentation r
ate. After 6 months of therapy anticardiolipin antibodies were within
normal limits. Only one similar case has been reported so far.
