Hematological ratios and cytokine profiles in heterozygous beta-thalassemia.

INTRODUCTION

β-Thalassemia is defined by a reduced or complete absence of β-globin chain synthesis in hemoglobin, leading to hemolytic anemia. Heterozygous β-thalassemia, also known as β-thalassemia trait (hBTh), the mildest form of this anemia, typically does not cause symptoms in carriers. However, it may lead to changes in the immune system, including an increase in total leukocyte, neutrophil, and lymphocyte counts.

OBJECTIVE

This study aimed to evaluate various immune and inflammation markers, including neutrophil/lymphocyte, derived neutrophil/lymphocyte, lymphocyte/monocyte, platelet/lymphocyte, neutrophil/platelet ratios, systemic immune-inflammation index, systemic inflammation response index, neutrophil/natural killer cell ratio (NNKR), and inflammatory cytokines in β-thalassemia trait carriers.

METHOD

A retrospective observational study was conducted, including 50 β-thalassemia trait individuals and 100 healthy controls.

RESULTS

Leukocyte, neutrophil and reticulocyte counts, and interleukin 6 levels were higher in carriers compared to controls. Notably, the β-thalassemia trait group had increased neutrophil/platelet, neutrophil/lymphocyte and derived neutrophil/lymphocyte ratios, and the systemic immune-inflammation and systemic inflammation response indexes were higher compared to the controls.

CONCLUSIONS

β-thalassemia trait shows a more pronounced inflammatory profile as indicated by hematological ratios. These ratios, therefore are potentially cost-effective and easily applicable markers for monitoring patients with the β-thalassemia trait.
