SIGNIFICANCE OF NEUTROPHIL-LYMPHOCYTE RATIO AND PLATELET-LYMPHOCYTE RATIO AS PROGNOSTIC MARKERS OF DISEASE SEVERITY IN SYSTEMIC LUPUS ERYTHEMATOSUS.

Managing systemic lupus erythematosus (SLE) is challenging because of its diverse symptoms, relapses, and issues related to immunosuppressive therapy. Hence, the management of autoimmune disorder has become a hot topic in this era. Thus, the study aims to predict disease severity in SLE cases by assessing the value of neutrophil-lymphocyte ratio and platelet-lymphocyte ratio. In this study, we included a total of 80 patients, of which 40 were controls and 40 were experimental group. We gathered the demographic data and each patient provided informed consent. Furthermore, the clinical examinations were done, and results were noted. The study compared 40 SLE patients with 40 controls. SLE patients had lower complement levels, higher rates of LN and encephalopathy, and elevated Hs-CRP and ESR. They also showed lower WBC, neutrophil, lymphocyte, and platelet counts, along with higher NLR and PLR. Higher SLEDAI scores correlated with elevated Hs-CRP and ESR, and lower C3. Neutrophils positively correlated with NLR, while lymphocytes negatively correlated with SLEDAI scores, NLR, and PLR. Platelets did not significantly correlate with these markers. SLE patients showed higher rates of LNand encephalopathy, elevated inflammatory markers, and altered blood cell counts. Lower SLEDAI scores correlated with less inflammation and higher C3 levels, potentially indicating disease severity. Neutrophils were closely linked to disease activity, while lymphocytes showed a strong negative correlation. Platelet count was not a significant marker. Understanding these aspects could improve diagnosis and management.
