Abstract

Thalassemia, which is associated with compound complications, is the most common hereditary anemia in the world. The zinc level is different in patients with thalassemias. This study aimed to determine the zinc status and its relationship with demographic factors and chelation therapy in β-thalassemia major (β-TM) patients. This cross-sectional study was conducted on 102 β-thalassemia (β-thal), patients. Zinc level was evaluated in subjects using the atomic absorption method. The results were analyzed through descriptive statistics, χ2 and Mann-Whitney U tests. Of 102 cases, 92 patients were eligible and evaluated. The mean age was 23 (minimum 11, maximum 43) years. Forty-six percent of cases were males and 54.0% were females. Of the 92 patients taking iron chelators, 29.3% used deferoxamine (DFO), 16.3% deferasirox (DFX), 20.6% DFO and deferiprone (DFP), and 33.8% DFO and DFP. All cases had zinc deficiency, 89.1% had zinc levels <40.0 mg/dL, and 10.9% with zinc levels >40.0 mg/dL. There was a significant relationship between gender and group with zinc levels greater than 40.0 mg/dL and those with less than 40.0 mg/dL. Zinc deficiency is highly prevalent among patients with thalassemia in the city of Yasuj, Iran. There was a significant relationship between zinc levels and gender although no significance was observed between zinc level and age, body mass index (BMI), ferritin, and chelation factors; it is recommended that these patients be periodically evaluated for zinc level. In case of a lack of laboratory evaluation, the use of prophylactic zinc supplementation should be considered for these patients.
