Juvenile idiopathic haemochromatosis: a life-threatening disorder presenting as hypogonadotropic hypogonadism.


It is generally believed that idiopathic haemochromatosis is exclusively a disease of middle age, affecting primarily men. We describe here four cases of idiopathic haemochromatosis having onset of symptoms before or around the age of 20 years. Other similar cases have previously been reported. In this juvenile form, males and females appear to be equally affected. These subjects may have a history of unexplained abdominal pain, present with hypogonadotropic hypogonadism, and, unless proper treatment is started, die early because of cardiac dysfunction. In this regard, their clinical course is very similar to that of well-transfused thalassemia major. Thus, early diagnosis is even more important in the juvenile form than in the adult form of idiopathic haemochromatosis. We suggest that evaluation of body iron stores should be performed as a screening procedure in young subjects with hypogonadotropic hypogonadism and/or cardiac dysfunction.
