Assessment of serum visfatin level in beta thalassemia patients

Abstract

Abstract Background Thalassemias are monogenetic hematologic disorders which are caused by faulty synthesis of one or more of the Hb chains which leads to imbalance in globin chains resulting in hemolysis and impaired erythropoiesis and chronic inflammatory condition. Visfatin is a pro-inflammatory adipocytokine which is mostly expressed in visceral adipose tissue and its testing may help in assessment of severity of the disease. Aim of the work This study aims at measuring serum visfatin level in Beta thalassemia patients and its possible correlation to disease severity (major andintermedia). Patients and methods Forty-one patients diagnosed as β-thalassemia (major, intermedia) and twenty age and sex-matched healthy individuals as the control group were tested for serum visfatin levels by enzyme-linked immunosorbent assay. Results Serum visfatin was higher in theß-thalassemia major(ß-TM) group than in the control group (P<0.001). Serum visfatinand serum ferritin were higher inß-TM group than in ß-thalassemia intermediagroup (ß-TI)(p < 0.001).Serum visfatin was found positively correlated with platelet count (P< 0.001) in the ß-TM group.As per ROC curve analysis, measured serum visfatin level was found to discriminate ß-TM group from β-TI group and control group. Conclusion There is an association between serum visfatin and the degree of severity of β thalassemia disease. Recommendations Testing of the relationship between serum visfatin level and other vascular inflammatory markers in β-thalassemia disease (asadiponectin, resistin, intracellular adhesion molecule (ICAM)) to clarify the exact mechanism of the inflammatory process in the disease and its complications to alter the course of the disease.Also to study serum visfatin in complicated β-thalassemia patients to establish its possible role in cardiac, vascular, endocrine or any other complications and comparing it with non-complicated patients.
