Abstract:
Background: Pemphigus is a group of rare, life-threatening bullous autoimmune diseases that affect the skin and mucous membranes and are associated with high morbidity and morbidity. HLA class II genes, particularly HLA-DRB1 and HLA-DQB1, play roles in pemphigus. Objectives: To investigate the susceptibility of HLA class II DRB1 and DQB1 alleles in Vietnamese patients with pemphigus vulgaris (PV) or pemphigus foliaceus (PF). Methods: The study enrolled 31 participants (22 with PV, 9 with PF) with diagnoses confirmed by clinical manifestations, histopathology, and direct immunofluorescence from November 2019 to June 2020. The HLA polymorphisms were determined by Sanger sequencing. The HLA-DRB1 and HLA-DQB1 profiles of the 101 healthy individuals in the control group have been published previously. Results: The frequencies of HLA-DRB1*14, DRB1*13:07, DRB1*04:04, DRB1*03:02, DQB1*02:02, and DQB1*05:03 were significantly higher, whereas those of DRB1*09:01, DRB1*12:02, DQB1*03:03, DQB1*05:01, and DQB1*06:01 were significantly lower, in the PV group than in the controls. The frequencies of DRB1*14:54, DRB1*13:07, and HLA-DQB1*03:02 were significantly higher in the PF group than in the controls. Conclusions: Alleles HLA-DRB1*14:54, DRB1*14:04, DRB1*14:03, DRB1*14:01, DRB1*14:12, DRB1*13:07, DRB1*04:04, DRB1*03:02, DQB1*02:02, and DQB1*05:03 were associated with an increased risk of PV, whereas alleles DRB1*09:01, DRB1*12:02, DQB1*03:03, DQB1*05:01, and DQB1*06:01 might protect against PV. In PF, DRB1*14:54, DRB1*13:07, and HLADQB1* 03:02 are promising susceptibility alleles.
