A relationship between T2*Liver and or T2*Heart levels and the number of blood transfusions.
Achtergrond van het onderzoek
This is a prospective study in MDS patients with IPSS low-risk, intermediate-1 or intermediate-2 risk. Information will be gathered at the entry of the study and during follow-up visits scheduled for routine patient care.
Primary objectives:
To evaluate the relationship between red blood cell transfusions and iron overload in liver and heart as investigated by MRI T2* in MDS patients.
To evaluate the relationship between the iron parameters (serum ferritin and transferrin saturation level) and iron overload as investigated by MRI T2* in blood transfusion-dependent MDS patients.
Secondary objectives:
To determine evidence for iron overload in transfusion-independent MDS patients due to ineffective erythropoiesis (serum iron, serum ferritin, transferrin saturation level, hepcidin, GDF15, sTfR and MRI T2*).
To determine evidence for iron overload in blood transfusion dependent MDS patients due to ineffective erythropoiesis (serum iron, serum ferritin, transferrin saturation level, hepcidin, GDF15, sTfR and MRI T2*).
Exploratory objectives:
To evaluate the effect of iron chelation therapy on the iron parameters and iron overload as investigated by MRI T2* (liver and heart) and to determine the best cut-off point to start iron chelation therapy.
To evaluate the relationship between the left ventricular diastolic function by echocardiography and iron overload in blood (serum iron, serum ferritin, transferrin saturation level, hepcidin, GDF15, sTfR) and iron overload as investigated by MRI T2*.
To determine if the presence of the HFE gene mutation has any influence on the severity of iron overload.
Study design:
Prospective, multicenter.
Duration:
3 years inclusion, 3 years of follow-up per patient.
Doel van het onderzoek
The hypothesis to be tested is the relationship between the number of blood transfusions, serum ferritin and transferrin saturation level and MRI T2*Heart, T2*Liver.
