The Correlation of Neutrophil-Lymphocyte Ratio and Eosinophil Count with SCORTEN in SJS/TEN.

INTRODUCTION

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are acute severe cutaneous adverse reactions commonly caused by medication. Precise evaluation of disease severity in initial setting must be obtained to start appropriate treatment. Neutrophil and lymphocyte ratio (NLR) plays a role in displaying inflammatory reaction while eosinophils count (EC) influences immunological dysregulation including the proliferation of cytotoxic cells in early onset of SJS/TEN.

OBJECTIVE

To evaluate whether NLR and EC serve as prognostic markers of disease severity in patients with SJS/TEN using SCORTEN.

METHODS

A single center study with retrospective study included SJS/TEN patients at Dr. Moewardi General Hospital Surakarta in January 1st 2018-December 31st 2020. The required laboratory data was assessed at the beginning of the patient's admission through medical records. The significance analysis were performed using one-way ANOVA and Spearman while the receiver-operator curve were used to evaluate the prognostic value of variables for severity in SJS/TEN patients.

RESULTS

The total sample in this study was 24 patients with majority female (58%) and range from 25 to >50 years (54%). The results demonstrated of significant difference and positively correlated between NLR and EC with severity of SJS/TEN (p<0.01; r>0.05). The specificity and sensitivity of 51%;61% and 70%;60%, respectively.

CONCLUSION

NLR and EC can be used as prognosticators of severity in SJS/TEN while further research on other inflammatory markers with increased number of samples and study centers are needed to provide more actual data.
