Objective: Beta thalassaemia minor is a common genetic disorder without any characteristic symptoms except mild anemia. It is found to be associated with some cardiovascular risk factors such as insulin resistance and diabetes mellitus. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to evaluate the RRI in subjects with beta thalassemia minor (BTM). Subjects and Methods: A total of 253 subjects were included in this cross-sectional study. The study group consisted of 148 subjects with BTM and the control group consisted of 105 healthy subjects. BTM was diagnosed by a complete blood count and hemoglobin electrophoresis. Blood pressure measurement and biochemical tests were performed. The RRI of all subjects was measured using renal Doppler ultrasonography. Results: Subjects with BTM had lower renal resistive indices compared to healthy subjects (0.58 +/- 0.04 vs. 0.60 +/- 0.06, p = 0.0016). Additionally, the RRI levels of subjects with BTM were correlated with systolic blood pressure (p = 0.017, r = 0.194). Conclusion: In this study, lower RRI were found in subjects with BTM. This may be associated with a decreased vascular resistance and blood viscosity in these subjects. (C) 2018 The Author(s) Published by S. Karger AG, Basel.
