[Intermediate thalassemia. Study of 5 cases in their clinical, ferrokinetic and erythrokinetic aspects]
Five cases of thalassaemia intermedia are reported, they being considered from clinical and biologic standpoints. All patients had long-lasting anaemia, variable enlargement of spleen and low transfusion requirements. The ferro-erythrokinetic pattern was that of chronic haemolysis with effective erythropoiesis, and some comments are included on the different patterns found in each genetic variety. None of the patients is subjected to a defined transfusion protocol.

Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
