The study protocol was approved by the University of Wisconsin-Madison Health Sciences Institutional Review Board. Informed written consent was obtained from subjects prior to participation. For studies of in vitro eosinophil activation, peripheral blood eosinophils were obtained from allergic subjects with and without mild asthma. Subjects with prescriptions for low doses of inhaled corticosteroids did not use their corticosteroids the day of the blood draw. Eosinophils were purified by negative selection as previously described [20 (link)]. Briefly, heparinized blood was diluted 1:1 in HBSS and was overlaid above Percoll (1.090 g/ml). After centrifugation at 700 × g for 20 min at room temperature, the mononuclear cells were removed from the plasma/percol interface and erythrocytes were eliminated from the cell pellet by hypotonic lysis. The remaining pellet was resuspended in 2% NCS in HBSS. Cells were then incubated with anti-CD16, anti-CD3, anti-CD14 and anti-Glycophorin-A beads from Miltenyi (San Diego, CA), and run through an AutoMACS (Miltenyi). Eosinophil preparations with purity > 99% and viability ∼98% were used the same day, ∼5 h after the blood draw.
For studies of in vivo eosinophil activation, bronchoscopy and bronchoalveolar lavage (BAL) were performed 48 h after segmental bronchoprovocation with an allergen (SBP-Ag) in subjects with mild asthma who were allergic to ragweed, dust mite, or cat dander allergens [20 (link)]. Eosinophils were purified, as previously described [12 (link)], from the BAL cell preparation (BAL EOS) and from peripheral blood (BBL EOS) of the same allergen-challenged subject. On the same day, eosinophils were also purified from peripheral blood of a control unchallenged subject (control EOS (Ctrl)).

Tissue samples were weighed and homogenized and the supernatants were harvested for later analysis [7 (link)]. The protein levels of cytokines and chemokines were detected by means of bio-plex suspension chip technology (BIO-RAD, Hercules, Ca) according to the manufacturer’s instructions. Total IgE and specific IgE levels to common airborne allergens were detected by the ImmunoCAP system (Phadia, Uppsala, Sweden). Specific IgE was determined for house dust mix (Hx2, Dermatophagoides pteronyssinus, Dermatophagoides farinae and Blatella germanica), mould mix (Mx2, Penicillium notatum, Aspergillus fumigatus, Candida albicans and Alternaria), animal epidermal and protein mix (Ex1, Dander from cat, horse, cow and dog), tree pollen mix (Tx4, Oak, Elm, Maple leaf sycamore, Willow and Cottonwood), weed pollen mix (Wx5, Common Ragweed, Mugwort, Marguerite, Dandelion and Golded rod) and staphylococcus aureus enterotoxin A (SEA) and B (SEB) [2 (link), 7 (link), 8 (link)].

Blood samples were obtained from both mothers and fathers during the first trimester of pregnancy. Serum total and allergen-specific IgE titers of mothers were analysed by a contract clinical laboratory by immunological assays. Serum total and allergen-specific IgE titers of mothers were assayed by ImmunoCAP (Thermo Fisher Scientific, Inc., Sweden). Specific titers were detected for the following allergens: Der p 1 (Dermatophagoides pteronyssinus), animal dander, Japanese cedar, birch, moth, and egg white. IgE levels were allocated into six classes: class 1 (0.35–0.69 UA/mL), class 2 (0.70–3.49 UA/mL), class 3 (3.5–17.49 UA/mL), class 4 (17.5–49.99 UA/mL), class 5 (50–99.99 UA/mL), and class 6 (≥100 UA/mL). Positive IgE sensitization to any allergen was defined as allergen-specific IgE ≥ 0.35 UA/mL to any of the allergens listed above. Total IgE titers were measured for the fathers using the same method.

Included patients were aged ≥18 years with a documented history of AC, a documented positive skin prick test and/or positive validated IgE test to perennial allergen (eg cat dander, dog dander, dust mites and/or cockroach) or to seasonal allergen (eg grass, ragweed, and/ or tree pollen) within 6 months before the study, or a positive skin prick test at Visit 1a and showing signs and symptoms of AC, ie tearing, itching and redness, that were likely to continue for the next weeks. The patients had to have a minimum score of 4 on a 0–10 numeric rating scale (0, no symptom; 10, very severe symptom) in at least one of three categories (ocular itching, ocular redness, and ocular tearing). The main exclusion criteria were a history of known contraindications or sensitivities to the use of the drug or any of its components; intraocular surgery or planned surgery during study participation and within 2 weeks after follow-up; ocular trauma in the 6 months before the study; clinical evidence of ocular herpes simplex or ocular herpes zoster infectious disease; or any clinically significant (CS) external ocular disease within 30 days before study start.

For all patients, demographic characteristics, severe asthma-related comorbidities (allergic rhinitis, chronic rhinosinusitis, and gastroesophageal reflux disease), asthma control test (ACT), asthma exacerbation that required at least three days of systemic corticosteroids, asthma treatment, fractional exhaled nitric oxide (FeNO) levels, pulmonary function (forced vital capacity, FEV1), and blood test (eosinophil proportion, serum total IgE, and serum aeroallergen-specific IgE (ImmunoCAP® total IgE and ImmunoCAP® specific IgE, Phadia K.K., Tokyo, Japan)) results before and 52 weeks after omalizumab administration were extracted by reviewing medical records. Patients with allergic rhinitis were diagnosed by an otolaryngologist (M.S.) or pulmonologists (T.T., T.K., Y.K., M.T., K.Y., and A.N.) according to the guideline.19 (link) Pretreatment serum aeroallergen-specific IgEs were classified into the following five groups:20 (link) house dust; dust mite (Dermatophagoides); mold (mixed molds [Penicillium, Cladosporium, Aspergillus, Candida, and Alternaria] and Trichophyton); animal dander (cat dander, dog dander); pollen (Japanese cedar, mixed grass (orchard grass, vernal grass, Bermuda grass and timothy grass), and mixed weed (ragweed, mugwort, oxeye daisy, dandelion and goldenrod)). Positivity of serum aeroallergen-specific IgE was defined as ≥0.35 UA/mL.21 (link) In all patients, serum specific IgEs against house dust and house dust mite were tested. The major component of house dust is house dust mite, though it includes house dust mite, animal dander, and mold.
Demographic characteristics and other variables listed above were assessed at baseline. Response to omalizumab treatment was then assessed in all patients. Demographic characteristics and other variables, including the positive ratio of serum specific IgE of each subgroup, were next compared between responders and non-responders. Univariate and multivariate logistic regression analyses were finally performed to clarify the predictors of responsiveness to omalizumab. Treatment responsiveness to omalizumab was determined by physicians’ overall evaluation according to the GETE scale at 52 weeks.22 (link) GETE is a five-point scale: excellent (complete control of asthma), good (marked improvement), moderate (discernible, but limited improvement), poor (no appreciable change), and worsening (overall deterioration of asthma control). Patients with an “excellent” or “good” response were defined as responders.
This study was approved by the Ethics Committee of Nagoya City University (60-20-0174). Written informed consent was waived by the ethics committee due to the retrospective nature of this study. Instead, an opt-out document was posted on the hospital website to offer patients the opportunity to refuse participation.
