AB1332 COST EFFECTIVE BIOMARKER IN PREDICTING SLE IN DEVELOPING COUNTRIES – NEUTROPHIL LYMPHOCYTE RATIO (NLR), PLATELET LYMPHOCYTE RATIO (PLR), MPV

Background SLE is a disease which is easily missed in regular clinical practice. In developing countries due to lack of investigation modalities and rheumatologist, early identification of the diseases process is delayed. By the time the patient reaches a higher medical care centre there is a significant time loss and advancement of the disease. NLR, PLR, RDW and MPV can be calculated from a complete blood count which will be available at any grass route heath centre. Objectives To identify Cost effective biomarkers in predicting SLE in developing countries. Focussing on markers - Neutrophil Lymphocyte Ratio (NLR), Platelet Lymphocyte Ratio (PLR), MPV. Methods This is a retrospective hospital based observational study conducted screening patients admitted from January 2016- November 2018 in with a diagnosis of SLE. We identified 150 patients with SLE and their NLR, PLR, and MPV data were collected and were correlated with equal control group without SLE Results We found that NLR, PLR, and MPV were highly significant with a p-value of 0.001 to be used as bio marker and also when further analysis was done using ROC curve with an area under curve of 76%, 81% and 78% respectively when compared with the control group. Conclusion We conclude that NLR,PLR,and MPV is cost-effective bio marker which costs ( References [1] Qin B, Ma N, Tang Q, Wei T, Yang M, Fu H, Hu Z, Ling Y, Yang Z, Zhong R Neutrophil, to Lymphocyte ratio (NLR) and Platelet to Lymphocyte Ratio (PLR) were useful markers in assessment of inflammatory response and disease activity in SLE patients.
