Abstract

Objectives

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.

Methods

Cross-sectional study using secondary data from Hasan Sadikin Lupus Registry. Parameters were examined using Sysmex XN-1500. Lupus activity was determined according to SLEDAI-2K.

Results

This study included 30 active (SLEDAI 2K ≥ 4) and 30 inactive SLE patients. Compared to inactive SLE, active SLE showed significantly higher Neut-RI (51.5 vs. 49.6 FL, p = 0.004), and lower Re-Lymph (0.09 vs. 0.14 × 10³/mm³, p = 0.024). There was no significant difference in Neut-GI (150 vs. 151.6 SI, p = 0.359), As-Lymp (0.02 vs. 0.01 × 10³/mm³, p = 0.621), and IG (0.11 vs. 0.06 × 10³/mm³, p = 0.384) between active and inactive SLE. Neut-RI/Re-Lymp ratio cutoff > 0.47 could distinguish between active and inactive SLE with AUC 0.689, 66.7% sensitivity, and 70.0% specificity.

Conclusion

In active SLE, there is an elevation in Neut-RI and a reduction in Re-Lymp. Neut-RI/Re-Lymp ratio exceeding 0.47 could be used to detect active SLE.

期刊介绍： The International Journal of Rheumatic Diseases (formerly APLAR Journal of Rheumatology) is the official journal of the Asia Pacific League of Associations for Rheumatology. The Journal accepts original articles on clinical or experimental research pertinent to the rheumatic diseases, work on connective tissue diseases and other immune and allergic disorders. The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer reviewed by two anonymous reviewers and the Editor.
