Abstract

Toxic epidermal necrolysis (TEN) and Stevens-Johnson syndrome (SJS) are acute, life-threatening mucocutaneous reactions, often triggered by drugs. Th2 cells and interleukin-31 (IL-31), secreted by Th2 cells, are thought to be involved in SJS/TEN. This study aimed to determine the role and influencing factors of IL-31 in SJS/TEN patients. This was a cross-sectional descriptive study in which serum IL-31 and IL-15 levels in SJS/TEN patients and healthy controls were measured using the fluorescence covalent microbead immunosorbent assay. The results included 26 patients (12 males, 14 females; 10 SJS patients and 16 TEN patients) with median ages of 49.5 and 51 years in the SJS and TEN groups, respectively, along with 18 healthy controls. The median interleukin-31 level in the SJS group was 0.22 pg/ml (interquartile range: 0.14-2.85 pg/ml), significantly higher than that in the healthy control group (p<0.05). The TEN group had a median IL-31 level of 0.14 pg/ml (interquartile range: 0.14-0.81 pg/ml), which was not significantly higher than that of the healthy group. A correlation was observed between interleukin-31 and interleukin-15 levels in the SJS group (r=0.899, p<0.001). Interleukin-31 may play a role in the pathogenesis of SJS/TEN, particularly in SJS.
