Effect of Chelation Therapy and Blood Transfusion on Trace Elements in Thalassemia Patients

Background: β-Thalassemia major is considered to be one of the most common inherited hemolytic anemia. Enhanced years of survival of thalassemia have led to unmasking related complications related to alterations in certain trace elements like magnesium, calcium, phosphorus, copper, zinc etc. Objective: Present study was conducted to evaluate the effect of iron chelation therapy and blood transfusion on certain trace elements (Magnesium, Calcium, Phosphorus, Copper, Zinc) in βthalassemic patients on chelation therapy more than one year. Materials and Methods: In the present cross sectional study, 100 β-thalassemic patients receiving chelation therapy for atleast 1year were recruited from Civil Hospital Ahmedabad, Gujarat during February, 2017 to December, 2018 and equal number (n=100) of healthy subjects were taken as a control group in the age range of 8 to 15 years of both sexes (male & female). The levels of serum magnesium, calcium, phosphorus, zinc, and copper in serum were analyzed and results were correlated with normal healthy subjects. Original Research Article Parmar et al.; IJBCRR, 28(4): 1-5, 2019; Article no.IJBCRR.53338 2 Results: A significant increase in serum copper (P≤ 0.01) and phosphorus (P≤ 0.001) were observed levels while a significant (P≤ 0.05) fall in magnesium, calcium and zinc levels recorded in β-thalassemic patients in comparison to healthy control subjects. Conclusion: Aforementioned observations suggested that fluctuations in the trace elements levels in βthalassemic children receiving blood transfusion and iron chelation therapy could leads to different complications like hemolyzed red cells, infections & hemochromatosis renal damage, hypoparathyroidism etc. if remains untreated. Hence routine assessment of these elements is recommended for better management.
