Analysis of Hematological Indices in Patients of Systemic Lupus Erythematous and Its Correlation with SLEDAI-2K.

: Systemic lupus erythematosus (SLE) is an autoimmune disease which is characterized by chronic multisystem inflammation and end-organ damage. In recent times there has been a need for new hematological markers to assess disease activity in SLE patients specifically, which can be easily available like eosinophil, basophil, neutrophil, monocytes, and platelet to lymphocyte ratios (ELR, BLR, NLR, MLR, and PLR, respectively). : The present investigation determines the use of a different peripheral hematological marker to assess SLE activity in 106 patients attended for medical care at Sawai Mansingh (SMS) Medical College and attached hospital, Jaipur. SLE disease activity index 2000 (SLEDAI-2K) was used to assess the disease activity in all patients. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were assessed in each subject. The ratio of various hematological indices, like NLR, BLR, ELR, MLR, PLR, etc., analyzed and correlated with CRP, ESR, and SLEDAI-2K. : The present study revealed that the SLEDAI-2K score showed a significant positive correlation with ELR and MLR ( < 0.005). CRP showed a significant positive correlation with PLR ( < 0.005). ESR showed a significant positive correlation with ELR, MLR, PLR, and NLR ( < 0.005). : The final results demonstrate that in SLE patients, the ratio of hematological indices like ELR, MLR, and PLR can be employed as disease activity markers. : Meena VP, Meena PD, Chejara RS, Analysis of Hematological Indices in Patients of Systemic Lupus Erythematous and Its Correlation with SLEDAI-2K.
