PG - 640-647 LID - 10.1089/thy.2022.0010 [doi] AB - Background: Despite mass vaccination, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine-induced subacute thyroiditis (SAT) is rarely seen as a complication. The reason why some individuals are susceptible to developing vaccine-induced SAT is not known. SAT develops in genetically predisposed individuals who carry specific human leukocyte antigen (HLA) haplotypes. It is unknown whether specific HLA alleles are associated with SARS-CoV-2 vaccine-induced SAT. Objective: This study compared the HLA profiles of patients with SARS-CoV-2 vaccine-induced SAT to controls, to assess whether there is an association between specific HLA genotypes and development of SAT. The relationship between HLA genotypes and the clinical course of SARS-CoV-2 vaccine-induced SAT was also evaluated. Methods: A case-control study was conducted in a Turkish tertiary care center. Fourteen patients with SARS-CoV-2 vaccine-induced SAT and 100 healthy controls were included. HLA-A, HLA-B, HLA-C, HLA-DQB1, and HLA-DRB1 frequencies were analyzed by next-generation sequencing. Results: The frequencies of HLA-B*35 and HLA-C*04 alleles were significantly higher in SARS-CoV-2 vaccine-induced SAT cohort when compared with controls (HLA-B*35: 13 [93%] vs. 40 [40%], p < 0.001; HLA-C*04: 13 [93%] vs. 43 [43%], p < 0.001, respectively). More severe thyrotoxicosis was seen in patients having HLA-B*35 and HLA-C*04 homozygous alleles (free thyroxine: 4.47 ng/dL [3.77-5.18] vs. 1.41 ng/dL [1.22-2.63], p = 0.048). Inflammation tended to be more severe in homozygous patients (C-reactive protein: 28.2 mg/dL [13.6-42.9] vs. 4.8 [1.2-10.5], p = 0.07). Conclusions: The frequencies of HLA-B*35 and HLA-C*04 alleles were higher in SARS-CoV-2 vaccine-induced SAT compared with controls. Homozygosity for HLA-B*35 and HLA-C*04 was associated with thyrotoxicosis and a greater inflammatory reaction. Our findings should be confirmed in studies of other populations.
