Evans syndrome
Background
Evans syndrome is an uncommon, but not rare, condition first described by Dr R S Evans and colleagues in 1951. It is a syndrome characterised by immune thrombocytopenia (see entry, Immune (Idiopathic) Thrombocytopenic Purpura) and autoimmune haemolytic anaemia. Onset is variable as is the course and duration of the syndrome. Evans syndrome affects people of all ages but is usually first diagnosed in young children. Individually, immune thrombocytopaenia and autoimmune haemolytic anaemia affect people of all ethnic groups but Evans syndrome may affect white people more than other ethnic groups.
