Effects of Hydroxyurea and Metformin in Transfusion Dependent Beta-Thalassemia

The study will be conducted after obtaining approval from the Institutional Review Board (IRB) at Bahria University Health Sciences Campus Karachi (BUHSCK) and the Faculty Research Committee (FRC). After obtaining written informed consent, 48 participants in each group with beta-thalassemia major will be selected from the National Institute of Blood Diseases and Bone Marrow Transplantation. Participants will be randomized into two treatment groups using computer-generated randomization.

Group A participants will receive Metformin 500 mg/dose twice daily orally for one year. Group B participants will receive Hydroxyurea 10-20 mg/kg once daily orally for one year.

Dose escalation therapy will be implemented to improve participant compliance and tolerance. The first month will not be included in the study period for each participant. A general physical examination will be conducted monthly. Blood pressure (mm Hg) will be assessed using a sphygmomanometer. The pulse rate (beats per minute) will be determined by palpating the radial artery, and the Body Mass Index (kg/m^2) will be calculated for each participant.

Dietary Counseling

People with thalassemia are advised to consume vitamin C-rich foods like vegetables and fruits to prevent depletion from iron overload. They should also include dairy products in their diet to counter calcium depletion, while avoiding high-iron foods such as beef, liver, spinach, and dates.
