Consents will be taken from patient or legal guardian after explaining to them the nature of the study.\n\nInclusion criteria\n\n1. Young beta thalassemia major patients (diagnosed by HPLC, CBC) who started transfusion therapy who received 5-7transfusions or less, aged more than 6 months.\n2. Pre-transfusional Hb should be \\>9 g/dL.\n3. Serum ferritin should be ≤ 500ng/ml, transferrin saturation ≤ 50%.\n\nExclusion criteria:\n\n1. Beta thalassemia intermedia patients, patients with other transfusion dependent anemias (myelodysplasia, other chronic hemolytic anemias , pure red cell aplasia , aplastic anemia )\n2. Patients with levels of ALT \\>5 the upper limit of normal (ULN), serum creatinine \\> ULN on 2 measurements.\n3. Patients with history of agranulocytosis \\[absolute neutrophil count (ANC) \\<0.5×109/L\\].\n4. Non complaint patients acknowledged by reviewing the patient's records.\n\nEnrollment period: expected to be 6 months period with a mean follow up period 12 months.\n\nRandomization: the patients enrolled as they entered the study and randomised alternatively either to arm 1 or 2 using a closed envelope system that devised by the statistician\n\nSample size: It was calculated to be 32 patients in each study group to detect significant difference at 0.05 with study power 95%\n\nArms, Groups and Cohorts:\n\nSixty-four thalassemia major patients naive to chelation therapy will be randomized into 2 groups: 1st group: with DFP 50 mg/kg for 12 months or 2nd group: no treatment arm\n\nActive Comparator arm : iron chelation Included 32 thalassemia major patients with low serum ferritin (≥500) . They will receive low dose DFP on 50 mg/kg/d.\n\nPlacebo Comparator arm: blood transfusion only Included 32 thalassemia patients with low serum ferritin (≥500). They receive blood transfusion with no chelation. Primary end point is elevation of SF to around 1000 ng/ml or more or Tsat \\> 90 % and or LPI \\> 0.6 Both groups will be followed up with intervals of 3 months both clinically and laboratory with a mean time of 12 months.\n\nPatients reaching serum ferritin ≥1000 will be subjected to dose escalation of DFP to 75 mg/kg/d.in Active Comparator arm and start of DFP 75MG/KG/D in Placebo Comparator arm.\n\nStudy procedures:\n\n1. Medical records of thalassemia patients will be reviewed \\& data will be gathered including:\n\n * Age at onset.\n * Transfusion history:\n\n * Amount in each transfusion: grams of administered RBCs\n * Frequency.\n * Calculation of the transfusion index in ml packed red cell per body weight in Kg per year.\n * Transfusional iron loading rate: This will be calculated from the blood volume transfused between baseline and the end of the study. The average iron content per transfusion unit, derived from the measured hematocrit. The transfusional iron loading rate will be then expressed in mg of the transfused iron per kg body weight per day.\n * History of viral hepatitis (hepatitis B and C virus).\n2. Laboratory investigations:\n\n 1. Pre-transfusion Complete blood picture (Both manual and electronic ANC ).\n 2. Liver and kidney functions.\n 3. LPI, Serum Ferritin, serum iron and transferring saturation measurement :\n\nSerum ferritin, transferring saturation (TSAT) and LPI will be checked prior to transfusion at base line, 3, 6, 9, and 12 month interval.\n\nPositive predictive value of LPI will be estimated in relation to TSAT, SF, frequency of blood transfusion, transfusion index, and transfusional iron loading rate at which patients will start oral chelation therapy.\n\nCompliance to ICT: Compliance to chelation therapy was assessed by reviewing patient self-report of dose-taking and the appropriate number of doses taken during each day was checked by prescription refills and measure amount of the drug in the retained bottles; a cutoff point below 70% was considered as poor compliance to the regimen."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD'], 'maximumAge': '36 Months', 'minimumAge': '6 Months', 'healthyVolunteers': False, 'eligibilityCriteria': "Inclusion Criteria:\n\n1.
