title: Use of Iron Chelating Agents in Transfusion Dependent Thalassaemia Major Patients.
abstract: This cross-sectional study was done to find and investigate the utilization pattern of iron chelating agents among 73 transfusion-dependent thalassaemia major patients with continuous enrolment for at least 1 year in a day care treatment centre run by The Thalassaemia Society of India, Kolkata from November 2014 to January 2015. Transfusion dependent thalassaemia major patients above the age of 2 years managed by various haematologists and Thalassaemia specialists were studied. The administration of iron chelators namely Desferrioxamine (DFO), Deferiprone (DFP) and Deferasirox (DFX) were evaluated. Forty seven (64%) of the thalassaemics had serum ferritin level below 2500 ng/dl, of whom 20(27%) patients have ferritin level below 1000ng/dl. A number of 55(75%) of 73 patients who were treated with a single chelating agent consisted 50 patients only on DFX. Exact 8(67%) patients were on DFO+DFP and 4(33%) are treated with DFX+DFP. The mean age was 19 and mean serum ferritin level was 2280 ng/dl among the thalassaemia major patients. DFX was used 68% of patients as monotherapy and 5% patients in combination therapy with DFP. DFX in the dose of 30-40 mg/kg/day was prescribed in 52% of patients. Mean dose of 15 mg/kg/day of DFX was been administered in combination with DFP (75 mg/kg/day) in 5% patients. DFO+DFP were preferred by 8 patients, out of which 6 were aged above 25. Cost of monotherapy is twice that of combination therapy. These data demonstrates the ferritin status and present scenario of utilization of chelating agents among thalassaemia major patients on repeated transfusions. The dosing of new drug, Deferasirox and the cost analysis of various chelating regimen has also been dealt. Individualization rather than rationalization of chelation therapy should be focussed upon in managing iron overload in thalassaemia.
