Microangiopathic haemolytic anaemia and systemic vasculitis.

ABSTRACT

Two cases of systemic vasculitis complicated by microangiopathic haemolytic anaemia (MAHA) are described this association has not previously been reported. Both patients had atypical presentations of their primary disease, one with parotitis and one with a Guillain-Barré syndrome. Other causes of MAHA were excluded and a possible link with macromolecular von Willebrands factor is speculated upon.
