The development of thyrotoxicosis (Graves' disease) during immunosuppression for autoimmune haemolytic anaemia

Abstract
A patient is described who developed thyrotoxicosis (Graves'' disease) during immunosuppressive therapy for acquired autoimmune haemolytic anaemia. The fact that the two conditions may be associated should be recognised. Long-term immunosuppressive therapy does not prevent the development of immunoglobulins of IgG type postulated to be aetiologically involved in Graves'' disease.
