Previous studies have found a strong association between HLA-B*1502 and carbamazepine-induced Stevens-Johnson syndrome in Asian areas including Taiwan, Hongkong and Thailand. This study explores the association between HLA-B*1502 allele and carbamazepine-induced cutaneous adverse reactions in Han Chinese of southern China mainland, and find the genetic marker that can predict carbamazepine-induced cutaneous adverse reactions. HLA-B*1502 allele genotyping was performed by a polymerase chain reaction-sequence specific primers (PCR-SSP) method in 48 Han Chinese subjects who had carbamazepine-induced cutaneous adverse reactions, including 9 severe cutaneous adverse reaction patients with Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) and 39 cutaneous adverse reaction patients with maculopapular eruption (MPE). Meanwhile 80 carbamazepine-tolerant controls and 62 healthy individuals were also tested. The frequency of HLA-B*1502 allele among SJS/TEN patients (100%) is significantly higher than carbamazepine-tolerant controls (13.75%, P<0.001) and healthy individuals (17.74%, P<0.001). But the frequency between MPE patients and carbamazepine-tolerant controls (25.64% vs.13.75%, P=0.110) did not have any significant difference. The data showed that HLA-B*1502 allele is strongly associated with carbamazepine-induced SJS/TEN but not MPE in Han Chinese of southern China mainland.
There is an increased incidence of PCOS in Chinese WWE at reproductive ages, by more than 2 times of that in the general population. Risk factors include seizures starting at a young age and VPA therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
