Abstract:
The use of lamotrigine ( LTG ) can be limited by the occurrence of cutaneous adverse drug reactions (c ADRs ) that range from maculopapular eruption ( MPE ) to the more severe Stevens‐Johnson syndrome and toxic epidermal necrolysis. A few human leukocyte antigen ( HLA )–related genetic risk factors for carbamazepine‐induced cADR have been identified. However, the HLA ‐related genetic risk factors associated with LTG ‐induced cADR are not yet well known. We performed HLA genotyping in 50 Korean patients with epilepsy, including 21 patients presenting LTG ‐induced MPE and 29 LTG ‐tolerant patients. A significant association between the HLA ‐A*2402 allele and LTG ‐induced MPE was identified, in comparison with the LTG ‐tolerant group (odds ratio [ OR ] 4.09, p = 0.025) and the general Korean population ( OR 3.949, p = 0.005). The frequencies of the Cw*0102 or Cw*0702 alleles were significantly higher in the LTG ‐ MPE group than in the Korean population, whereas the frequency of the A*3303 allele was lower. The coexistence of the A*2402 and Cw*0102 alleles was significantly associated with the LTG ‐ MPE group when compared to the LTG ‐tolerant group ( OR 7.88, p = 0.007). In addition, the Cw*0701 allele was more frequent in the LTG ‐tolerant group than in the Korean population. These findings suggest the presence of HLA ‐related genetic risk factors for LTG ‐induced MPE in the Korean population.
