简要总结
Recently, it has been demonstrated that iron overload is associated with the appearance of labile plasma iron (LPI).
LPI is redox active and is rapidly taken up by cells, leading to a rise in the labile iron pool (LIP) and catalyzing generation of reactive oxygen species (ROS), which can lead to cellular damage.
The LPI data are mostly derived from thalassemia iron overload research , however, there are a few data describing LPI and its correlations with the classical iron overload parameters (ferritin, TSAT) in acute anemias such as MDS Therefore we are going to assess LPI in iron overloaded myelodysplastic syndromes (MDS) (low and high risk) and primary myelofibrosis, in order to assess whether it can be used as alternative to the routinely used parameters; TSAT and ferritin levels.
详细描述
Approximately 60-80% of patients with myelodysplastic syndromes (MDS) present with symptomatic anemia and 80-90%, of these, will require red blood cell (RBC) transfusions. Excess transfusional iron causes iron overload (IO) which is characterized by elevated serum ferritin (> 1000ng/ml) and transferrin saturation (TSAT > 50%) levels.
Assessment of IO using serum ferritin and TSAT levels is not accurate enough and this is due to changes in serum ferritin and TSAT during any inflammatory condition.
Since serum ferritin is considered as a positive acute phase reactant and therefore inflammatory state can lead to an increase in serum ferritin levels and so does not reflect the exact amount of iron overload.
In contrast TSAT can decrease during inflammation and in addition it follows diurnal variations.The aim of our present study is to asses the levels of LPI in patients with in iron overloaded MDS patients (low and high risk), and also patients with primary myelofibrosis, in order to find out any laboratory correlations between LPI, TSAT and srum ferritin levels.

结局指标
主要结局
The value of Ferritin,Transferrin Saturation,CRP and LPI at the blood samples
时间窗: 1 year
The blood samples should be taken at least one week apart from last blood transfusion. In case of infection or acute inflammation , blood samples should be taken only one week after resolution of these conditions.
