Abstract

Background: Folate deficiency has been found in Beta-thalassemia major (?-TM ). However, its impact with mitochondria DNA damage  status has not been addressed. The study aimed to investigate  the serum folic acid in ?-TM patients and to determine an association between serum FA deficiency and mitochondria DNA damage. Methods: A total of 80 patients who were diagnosed with ?-TM patients  were enrolled in the study and divided into two groups:45 ?-TM  who were not receiving folic acid (FA)and  35 ?-TM  who were receiving  folic acid 5 mg/day (?-TM +FA),  40 healthy subjects were consider as control. A blood sample (5 ml) was taken from all study groups. 1 ml was used for the complete blood count (CBC) Neutrophils/lymphocytes ratio analysis and mtDNA damage by conventional PCR. Serum was separated from other 4 ml of blood by centrifugation for folic acid  analysis by immunochromatographic assay. serum Ferritin was measured by an enzyme-linked fluorescence immunoassay. Results: the results were demonstrated a significant decrease in serum folic acid (P < 0.05) in both patients groups as compared with control (P<0.05).Serum ferritin levels increased significantly in both patient groups as compared with control. The results of conventional PCR for mtDNA damage showed mtDNA damage in ?-TM compared to control. Conclusion: The folic acid deficiency and iron overload  due to repeated blood transfusion in patients with ?-TM may cause  more mtDNA damage.
