title: [Anaemia in adopted children, not always iron deficiency].
abstract: Anaemia was diagnosed in four adopted children during a standard screening examination 1-4 weeks after arrival. Further investigation revealed a number of causes which could then be specifically treated. The children were a girl aged 14 months from China with iron-deficiency anaemia, a boy aged 16 months from Nigeria with sickle cell anaemia, a girl aged 5 from Haiti who had alpha-thalassaemia, and a boy aged 7 from Brazil with spherocytosis. Iron deficiency is the most common cause of anaemia in childhood. However, in adopted children from sub-tropical areas other causes of anaemia like haemoglobinopathies or erythrocyte membrane defects should be borne in mind, particularly as a history of disease and family history are often lacking. Additional investigations may be necessary. An incorrect diagnosis of iron deficiency may result in ongoing and unjustified iron supplementation leading to harmful iron accumulation in thalassaemia and a delay in the correct treatment in sickle cell anemia or spherocytosis which could carry considerable risk.
