Abstract
Purpose
The purpose of this study is to examine the association of HLA-B*1502 allele with CBZ-induced SJS/TEN in the mainland Han Chinese population.
Methods
HLA-B*1502 genotyping with sequence-specific primer polymerase chain reaction (PCR-SSP) and PCR-sequencing based typing (PCR-SBT) was performed on 17 CBZ-induced SJS/TEN patients, 21 CBZ-tolerant controls, and 185 healthy controls recruited during 2008–2010.
Results
HLA-B*1502 allele was present in 94.1% (16/17) of CBZ-SJS/TEN patients, 9.5% (2/21) of CBZ-tolerant patients, and 9.2% (17/185) of healthy controls. The risk of CBZ-induced SJS/TEN was significantly higher (P < 0.01) in the patients with HLA-B*1502. One CBZ-induced SJS patient tested negative for HLA-B*1502, and the test result showed HLA-B*3503/B*4601.
Conclusions
We found a strong association between HLA-B*1502 and CBZ-induced SJS/TEN in the Han Chinese population from central and northern China. Combined with previous studies of the southern Han Chinese subpopulation, our results suggest that HLA-B*1502 is strongly associated with CBZ-induced SJS/TEN in the whole Han Chinese population.
