BIOCHEMICAL STUDY OF SERUM β-HYDROXYBUTYRATE DEHYDROGENASE IN β-THALASSEMIA

Abstract

Introduction: Thalassemia is a healthcare challenging disease all over the world. It imparts a great burden on patients’ families and healthcare institutions. Scientists focus on new aspects to overcome these challenges and increase patient tolerance of disease complications. This study aims to quantify β-Hydroxybutyrate Dehydrogenase BHBDH activity in thalassemia patients compared to the control group and their correlation with the patient's demographic characteristics. Methods: To do so, serum was collected from patients and the control group and analyzed biochemically for targeted laboratory tests. We determined β-Hydroxybutyrate Dehydrogenase from normal human serum using biochemical molecular techniques. Results: The results showed that BHBDH activity is significantly higher in the patients compared to the control group regardless of age, sex, or marital status. The results confirmed that enzyme activity and the purification folds were (0.0214 U/ml) and (51.7) respectively for the partially purified enzyme. Furthermore, the proportional molecular weight of the incompletely isolated β-Hydroxybutyrate Dehydrogenase was (125.8±0.5 kDa) using gel filtration chromatography. The comparative molecular weight of the subunit of partially isolated β-Hydroxybutyrate Dehydrogenase was (32.1±0.5 kDa) using SDS–PAGE. Conclusion: we demonstrate that BHBDH enzymatic activity is higher than control and this could be a prognostic or diagnostic tool in thalassemia patients.
