title: DNA typing of HLA class II genes (HLA-DR, -DQ and -DP) in Japanese patients with histiocytic necrotizing lymphadenitis (Kikuchi's disease).
abstract: The pathogenesis of histiocytic necrotizing lymphadenitis (HNL), which was reported first by Kikuchi et al. and Fujimoto et al. in 1972, is as yet unknown. HNL is frequently reported in Asian countries including Japan, however it is rare in Europe and North America. To elucidate whether the human leukocyte antigen (HLA) alleles and haplotypes are associated with HNL, we performed DNA typing of HLA class II genes (HLA-DR, -DQ, and -DP) in 86 patients with HNL and 525 unrelated healthy Japanese controls with polymerase chain reaction using sequence-specific oligonucleotide probes (PCR-SSOP). In this study, we found DPA1*01 and DPB1*0202 allele frequencies in HLA class II genes are significantly higher in HNL patients than in normal controls. It is known that the frequency of DPB1*0202 alleles is extremely low or absent in Caucasians (e.g., French 0.4%, Italian 0.8%) and Negroid (e.g., South African 0%, Hottentot 0%), but relatively frequent in Asians (e.g., Korean 9.9%, Japanese 4.5%). Previous reports have said the incidence of HNL is frequent in Asians but rare in other races. In light of this background, HLA class II genes of HNL and the incidence of HNL in Asian countries, including Japan, might have a positive relationship to DPA1*01 and DPB1*0202 allele.
