[Blood iron and ferritin in the monitoring of Hodgkin's disease].

A number of biohumoral parameters were investigated in monitoring the clinical course of Hodgkin's disease (H.D.). Blood iron and ferritin levels were found to be extremely useful. Blood iron is a significant indicator of the activity of the disease since the level falls in the acute phase and returns to normal on remission. Blood ferritin is less sensitive but closely related to the presence or absence of systemic symptoms so that in clinical practice it serves as an indicator of a poor prognosis.
