1 The effects of house dust mite sublingual immunotherapy tablet on immunologic biomarkers and nasal allergen challenge symptoms  Natasha C. Gunawardana, MBBS, Qing Zhao, PhD, Leonidas N. Carayannopoulos, MD, PhD, Kuenhi Tsai, PhD, Vladislav A. Malkov, PhD, Diana Selverian, BSN, Graham Clarke, PhD, Tim Mant, MB, Brent D. Butts, PhD, Kaare Lund, PhD, Trevor T. Hansel, FRCPath, PhD, Hendrik Nolte, MD, PhD  Journal of Allergy and Clinical Immunology  Volume 141, Issue 2, Pages e9 (February 2018) DOI: /j.jaci Copyright © 2017 American Academy of Allergy, Asthma & Immunology Terms and Conditions

2 Fig 1 Effect of 12 SQ-HDM treatment on serum antibody-related parameters (A) and NAC-induced symptoms (B). Values are least squares geometric mean ± 95% CI for IgG4, and least squares mean ± 95% CI for IgE-BF. *P < .05 for difference in ratio of geometric mean (IgG4) or change from baseline (IgE-BF) vs placebo. †Percent change from baseline NAC at 15 minutes. ‡P = .02 vs placebo. mgA/L, Milligram antibody per liter.

3 Fig 2 Effect of 12 SQ-HDM treatment on NAC-induced IL-5 concentrations (A) in mucosal lining fluid and nasal cell mRNA markers (B). Error bars for IL-5 concentrations indicate minimum and maximum values. Fold changes are estimated and the fold change at baseline is assumed to be the same for both treatment groups.

6 Fig E3 Subject-level protein concentrations in nasal mucosal lining fluid at 1 hour pre-NAC, 15 minutes post-NAC (except TARC), and 6.5 hours post-NAC at weeks −2, 8, and 12 for IL-5 (A), IL-13 (B), and TARC (C). BLOQ, Below limit of quantitation. Journal of Allergy and Clinical Immunology  , e9DOI: ( /j.jaci ) Copyright © 2017 American Academy of Allergy, Asthma & Immunology Terms and Conditions
