PG - 12-5 LID - S0920-1211(16)30055-9 [pii] LID - 10.1016/j.eplepsyres.2016.04.008 [doi] AB - PURPOSE: This study aimed to evaluate the clinical characteristics of levetiracetam (LEV)-induced cutaneous adverse drug reactions (cADRs) and to explore its possible genetic association with the human leukocyte antigen (HLA) genes. METHODS: Nine cases with LEV-induced cADRs were recruited. Demographic and clinical information of these cases was summarized. Additionally, cases were matched with LEV-tolerant controls (1:4). High-resolution HLA class I and class II genotyping was performed for each participant. The allele frequencies between the cases and controls were compared. RESULTS: All LEV-induced cADRs were mild skin rashes which occurred within 28 days of LEV exposure. The mean latency from LEV exposure to skin rash was (15.67+/-5.41) days (ranging 6-27). The carrier rates of the two alleles, HLA-DRB1*0405 and HLA-DQB1*0401, were higher in cases compared with controls (the same P=0.036, OR=13.875, 95% CI: 1.273-151.230). The association between the HLA-C*0304 allele and LEV-induced cADRs was boundary (P=0.05, OR=5.2, 95% CI: 1.086-24.897). However, the above-mentioned HLA alleles didn't reach statistical significance after multiple comparisons. CONCLUSIONS: Safety monitoring was necessary within four weeks after the initiation of LEV treatment, although it has been regarded as a safe antiepileptic drug. Our study failed to show any potential link between HLA alleles and LEV-induced cADRs in Han Chinese. Further studies are needed to clarify the genetic and immunological mechanisms of LEV-induced cADRs. CI - Copyright (c) 2016 Elsevier B.V. All rights reserved.
