Abstrakt: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired immunological disorder. Although the precise pathoetiology of CIDP has not been clarified yet, it is believed that both B and T cells of immune system contribute in this disorder. Based on the importance of human leukocyte antigen (HLA) cluster in the regulation of immune responses, this family of proteins is putative determinants of risk of CIDP. We conducted the current investigation to appraise association between HLA alleles/genotypes/haplotypes and risk of CIDP in Iranian patients. HLA-DQB1*02 allele was significantly more prevalent among cases compared with controls (OR [95% CI] = 4.82 [2.06, 11.3], P value = 0.000215, adjusted P value = 0.0124). A*01-B*52-C*12-DRB1*15-DQB1*02 and A*23-B*35-C*04-DRB1*11-DQB1*03 haplotypes with frequency of 0.03 were the most frequent HLA haplotypes. These haplotypes were not detected among healthy controls. The present study introduces HLA-DQB1*02 allele as a risk allele for CIDP among Iranian patients and further supports the importance of HLA region in this immunological condition.
