Plain language summary

T-cell and antibody responses to severe acute respiratory syndrome coronavirus 2 vaccination in inflammatory bowel disease patients are poorly correlated. T-cell responses are preserved by most biologic therapies, but augmented by anti-tumor necrosis factor (anti-TNF) treatment. While anti-TNF therapy blunts the antibody response, cellular immunity after vaccination is robust.

T-cell clonal response to SARS-CoV-2 immunization. (A) Box plots show means, quartiles, and data ranges. Relative to dose 1, P values (mixed-effect model analysis with adjustment for age and sex) for dose 2, at 2 weeks after the second vaccination, and at 8 weeks after the second vaccination were 9.87E-11, 2.42E-25, and 5.30E-14, respectively (n = 88 at dose 1, 148 at dose 2, 136 at 2 weeks, and 163 at 8 weeks). (B) Age. Numbers of subjects by age group are tabulated in Table 1. (C) Immunologic treatment and response at week 2. No Imm (n = 19), anti-integrin (n = 14), anti-IL23 (n = 36), anti-TNF mono (n = 36), anti-TNF cmb (n = 11), steroids/small mol (n = 16). Boxes are mean values, bars are data ranges, and P values were calculated by ANOVA after adjustment for age, sex, vaccine type, and COVID-19 history. (D) T-cell response and anti-spike IgG levels at week 2 (Spearman’s correlation; N = 148). (E) T-cell response at week 2 (blue, lowest quartile; red, remaining quartiles; N = 148). (F) Anti-spike IgG levels at week 2 by subject distribution (blue, lowest T-cell response quartile; red, remaining T-cell response quartiles; N = 148). Abbreviations: anti-TNF cmb, combined therapy with anti-tumor necrosis factor and a thiopurine or methotrexate; ANOVA, analysis of variance; anti-TNF mono, monotherapy with anti-tumor necrosis factor; Ig, immunoglobin; IL, interleukin; JAK, Janus kinase; no Imm, no treatment, 5-aminosalicylates, or rectal steroids; SARS-CoV-2, severe acute respiratory syndrome coronavirus 2; steroids/small mol, treatment with systemic corticosteroids or monotherapy with thiopurines, methotrexate, or Janus kinase inhibitors; TNF, tumor necrosis factor.
