Criteria for Pediatric Patients Selection for Omalizumab Basic Therapy as the Main Factor in the Long-Term Control of Severe Bronchial Asthma

Introduction. Bronchial asthma (BA) pathogenesis is settled by bronchial wall inflammation, which is the main treatment target.Aim. To study the dependence of thymic stromal lymphopoietin (TSLP) concentration in serum and nasal brush-biopsies from age, spirometry data deterioration and blood eosinophils in patients with uncontrolled BA.Materials and methods. Patients with uncontrolled BA of three age groups: children (6–11 y.o., n = 38), adolescents (14–17 y.o., n = 35) and adults (25–50 y.o., n = 31) were included in 1-year long open prospective study. Clinical history, АСТ/сАСТ questionnaires, lung function test (LFT), common blood count, serum and nasal material to evaluate TSLP were obtained during first visit, if there were no any signs of acute respiratory infection for not less than 14 days. Maintenance therapy was revised based on firstvisit findings. Patient were consequently examined twice with 6 months intervals, examination data, LFT readings, ACT results and eosinophil counts were collected. Statistical analyses included ANOVA (Kruskal-Wallis test) and Pearson’s correlation (r). Differences accepted significant with р < 0,05.Results. Serum TSLP levels did not differ between age groups. TSLP concentration correlate directly and significantly with duration of uncontrolled BA in previous 12 months (r = 0.74). In patients with atopic BA, maximum TSLP level was in dust mites sensitized group (792.6 ± 114.1 pg/ml). We have found greater serum TSLP concentration in patients who demonstrated FEV1 below normal even on optimal controller therapy at Visit 3. Eosinophil count randomly changed inside normal values and did not correlate with asthma control or TSLP level.Conclusion. Prognosis of future asthma exacerbations and LFT decrease is less favourable in patients with high serum TSLP level.

Introduction. Uncontrolled bronchial asthma (BA) increases risk of hospitalizations, future exacerbations and decreases quality of life; factors improving the probability to achieve BA control are under study.Methods and materials. The open prospective study included 104 patients of three groups: children (6—11 years, n=38), adolescents (14—17 years, n = 35) and adults (25 — 50 years, n = 31). Inclusion criteria: BA duration >12 month, uncontrolled asthma, absence of acute respiratory infection for 14 days. Clinical history, respiratory function and sampling (serum and nasal brushings) for periostin assay were performed on Visit 1. Maintenance therapy correction and triggers avoiding recommendations were made. Two further visits 6 months apart were done. Statistical processing included ANOVA (Kruskall — Wallis test) and Pearson correlation test. Differences were considered significant when p<0.05.Results. 75 % of «Children» group,70.6 % of «Adolescents» and 53.6 % of «Adults» had achieved BA control. Obesity, non-atopic phenotype, FEV1 <65 % of predicted were risk factors of uncontrolled BA. Serum periostin levels were highest in uncontrolled BA subgroup, Me [Q25; Q75] =32.9 [28.6; 39.1] ng/ml. Nasal periostin levels were highest in «Adolescent» group: 9.8 [4.8; 11.2] ng/ml. Nasal periostin and low FEV1 had moderate reverse correlation (r=—0.61).Conclusion. Serum and nasal periostin levels could indicate treatment efficacy and prognose future risks of BA control loss.
