A concurrent parallel study to compare the efficacy and safety of oral iron chelators, defrasirox and defriprone in patients of beta thalassaemia major

Background: This study was planned to evaluate all the cases of ? thalassaemia major, already receiving one of the oral iron chelators for a comparison among the efficacy, safety and economy of deferasirox and deferiprone to establish the better option in an Indian scenario.Methods: We identified two groups of patients: 38 treated with deferasirox and 35 treated with deferiprone. Laboratory parameters such as serum ferritin, creatinine, SGPT, Hb, CBC and urine were recorded at the time of inclusion and at 1, 3 and 6 months after the inclusion. The primary outcome variable was serum Ferritin level at the start and at the end of study. Serum ferritin level was carried out by microparticle enzyme linked immunoassay.Results: Before the study, the mean hemoglobin level was 7.32±1.50mg/dL ranged from 4 to 10.8 in deferasirox group and 7.54±1.15mg/dL ranged from 5.5 to 8.8 in deferiprone group. At the time of inclusion, study population was characterized by a mean serum ferritin value of 4735.11±450.01 SE in deferasirox and 4315.97±340.75 SE in deferiprone group. After one month the mean serum ferritin increases to 4578.66±371.96 in deferasirox and 4388.82±316.16 in deferiprone group. After three month the mean serum ferritin reduces to 4295.60±377.37 in deferasirox and 3988.88±349.84 in Deferiprone group.Conclusions: Thus, we conclude that deferasirox and deferiprone are well tolerated, have few adverse effects and almost have a comparable effect in lowering of the patient's serum ferritin level. Deferiprone is more cost effective but needs a strict control on compliance owing to requirement in three divided doses per day.

Cranial neuroimaging in infantile tremor syndrome (ITS).

Clinical, hematological and cranial neuroimaging findings of eight cases of infantile tremor syndrome are reported. All had coarse tremors, anemia, hyperpigmentation and delayed or regression of developmental milestones. Five patients had microcytic, hypochromic anemia, three had dimorphic anemia. CT scans of two cases and MRI scans of three cases showed cerebral atrophy. One of these two CT scans, in addition, showed a small hypodensity in right basal ganglia region. Two CT scans were normal. One MRI showed hyperintense signals in frontal and periventricular white matter on T2 weighted images. The changes described are non-specific and also seen in cases of malnutrition and viral infections of CNS.
