Abstract
We previously reported that PTGER3 (prostaglandin E receptor 3 (subtype EP3)) single-nucleotide polymorphisms (SNPs) were associated with Stevens–Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN) with severe ocular complications (SOC). We also documented that approximately 80% of our SJS/TEN patients had taken cold medicines within several days before disease onset, and we thus designated them cold medicine-related SJS/TEN (CM-SJS/TEN) patients. Moreover, we reported that HLA-A*02:06 with TLR3 polymorphisms exerted more than additive effects in SJS/TEN with SOC. In this study, we focused on CM-SJS/TEN with SOC and analyzed the association with PTGER3 SNPs and an interactive effect between PTGER3 SNPs and HLA-A*02:06 in not only the Japanese but also the Korean population. In the Japanese population, PTGER3 SNP rs1327464 was most significantly associated with CM-SJS/TEN with SOC (G versus A; odds ratio (OR) = 0.232, P = 7.92 × 10− 10), and we found an interaction with additive effects between HLA-A*02:06 and the high-risk genotypes PTGER3 rs1327464 GA or AA (OR = 10.8, P = 2.56 × 10− 7). We also found a significant association between Korean CM-SJS/TEN with SOC and PTGER3 SNP rs1327464 (GG versus GA+AA, OR = 0.246, P = 0.00101), and we detected an additive effect between HLA-A*02:06 and the high-risk genotypes PTGER3 rs1327464 GA or AA (OR = 14.2, P = 5.58 × 10− 6).
