The Potential Role of Neutrophil Reactivity Intensity and Reactive Lymphocytes as Extended Hematological Parameters to Detect Active Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease characterized by the presence of autoantibodies against nuclear antigens and immune complex deposition. The pathogenesis of SLE is not fully understood; however, there are alterations in neutrophils and lymphocytes. Recent parameters assessing both neutrophil activations (Neut-RI, Neut-GI, IG) and activated lymphocytes (Re-Lymp, As-Lymp) can be used to assess the activation of immune cells. The aim of this study was to explore the potential role of this parameter in detecting active SLE.
