Iron overload and liver function in patients with beta thalassemia major: A cross sectional study.

Objective: In thalassemia major, repeated blood transfusions result in iron overload causing organ damage. The objective of this study was assessment of liver enzymes in patients with Thalassemia major and to observe their association with ferritin. Method: A cross-sectional study was performed, at Islamabad Medical and Dental College and its affiliated Akbar Niazi Teaching Hospital from November 2021 till August 2022. Serum ferritin, AST, ALT, and total bilirubin levels were determined, in 135 patients of beta thalassemia major receiving transfusions. Data analysis was performed using SPSS Version 20. For categorical variables, calculation of frequencies and percentages was performed. Mean (± standard deviation) was determined for quantitative variables. ANOVA with post hoc Tukey's test was used for determining association between liver enzymes and serum ferritin. A p-value of <0.05 was considered significant. The correlation between ferritin and LFTs was determined by Pearson's correlation coefficient. Results: Patients had an age range of 7-30 years, and males constituted 51% of sample. Mean level of ferritin was 6062.61 + 3641.79 ng/ml, with an insignificant difference between the genders ( Conclusion: Liver damage was caused by increased iron deposition. LFTs should be performed regularly to detect and reduce liver damage by increasing chelation therapy, thereby reducing morbidity and mortality due to thalassemia.
