BACKGROUND AND OBJECTIVES: Pemphigus is an autoimmune bullous disease of the skin and mucous membranes. There are two major types of pemphigus, namely pemphigus vulgaris(PV) and pemphigus foliaceus(PF) which can be classified by the specificity of the autoantibodies against the epidermal desmosomal antigens in this disease. Like many other autoimmune diseases, pemphigus is also considered to be strongly associated with certain HLA alleles; some alleles can be detected with higher frequencies as compared with those found in ethnically matched populations. At this time, we tried to find out if there were certain HLA class II allele(s) associated significantly with Korean patients of pemphigus. PATIENTS AND METHODS: Thirty patients with pemphigus (fifteen of PV and fifteen of PF), and one hundred healthy Korean controls were enrolled in this study. For the genotyping of HLA class II alleles in DRB1 loci, genomic DNAs prepared from buccal epithelia were amplified by polymerase chain reactions with nucleotide sequence-specific primers. Each allele of thirteen different generic types belonging to the DRB1 loci were used to identify the existence of each allele in both patient and control groups on gel electrophoreses. RESULTS: In PV, there was a significantly increased frequency of HLA-DRB1*01 alleles than from the findings observed in the controls(pc=0.0013, RR:5). In patients with PF, there was a significant degree of association with HLA-DRB1*01(pc=0.00013, RR:5.5) when compared with that in normal controls. However, no allele of negative association with a significantly low frequency in the patient group was detected in both types of the disease. CONCLUSION: It can be suggested that DRB1*01 alleles may be susceptibility genes in Korean patients with PV, and DRB1*01 alleles could contribute to the autoimmune reactivity in patients with PF. This data shows different patterns in the frequency of each DRB1 allele in patient groups compared with those found in patients of other ethnic backgrounds.
