[Hemoglobinopathies. Current therapeutic possibilities].

In recent years, the number of immigrants has increased considerably in Denmark. Consequently, a series of new clinical pictures has appeared in the Danish health care system. Typical examples are the genetic diseases, the haemoglobinopathies. Most of the immigrants come from areas, where the gene frequency of these disorders is widely distributed, for instance the Mediterranean countries, the Middle East, Southeast Asia and Africa. Most frequent are the heterozygous thalassaemias, but also the number of patients with severe thalassaemia and other clinically important haemoglobinopathies such as sickle cell anaemia has also increased in recent years. The clinical problems concerning these patients focus on two important topics, namely genetic counselling of heterozygous individuals (in some cases combined with prenatal diagnostics) and the treatment of patients with clinically severe haemoglobinopathy. The only curative treatment of the haemoglobinopathies is allogeneic bone marrow transplantation, but this treatment can only be offered to a few of these patients. However, a variety of therapeutic options exist which can improve their prognosis and quality of life. Since the number of patients with these diseases will probably increase over the next years we find it relevant, based on typical case stories, to give a review of the present therapeutic possibilities for these disorders.
