Abstract:
Objective To investigate and analyze the similarities of allergens in children of the same family with susceptibility to the same genetic background and environmental factors. Methods From January 2013 to December 2017,a total of 142 pairs of children with allergic diseases aged 0-15 years and their siblings ( 284 cases) were collected from the outpatient or hospitalized treatment of Pediatrics and otolaryngology department of the First People′s Hospital of Foshan City,the Third Affiliated Hospital of Sun Yat-sen University. The elder group was brother or sister (142 cases),and the younger group was brother or sister ( 142 cases ) . The serum allergen sIgE was tested by Allergy Screen allergen detection system (developed by Germany MEDIWISS Company) and the similarity of allergens was analyzed. Results A total of 142 siblings ( 284 cases ) had systemic symptoms of allergic diseases in varying degrees, including respiratory symptoms ( cough ( 47 cases in the old group,32 cases in the young group), χ2 ＝3. 946, P＝0. 047),nasal obstruction ( 41 cases in the old group,19 cases in the young group, χ2 ＝ 10. 227, P ＝0. 001),runny nose (46 cases in the old group,26 cases in the young group,χ2＝7. 442,P＝0. 006), gastrointestinal symptoms (abdominal pain (11cases in the old group,7 cases in the young group,χ2＝4. 63, P＝0. 031),skin symptoms(urticaria (18 cases in the old group,8 cases in the young group,χ2＝4. 234,P＝0. 037)) and so on,the difference was statistically significant. Some children have multiple organ system symptoms at the same time. There was no significant difference between the old group and the young group in the early use of antibiotics,mode of production and feeding mode within 6 months (all P＞0. 05). Among the two groups,house dust mite and cockroach (r＝0. 831,P＜0. 05),dog hair and house dust ( r＝0. 717,P＜0. 05),cypress,elm,willow,birch,oak,maple,walnut,sycamore,poplar and Dianqing,branching,yanqu, and heiqu ( r ＝ 0. 683, P＜ 0. 05 ) . Conclusion With the same genetic background and the same environmental factors,the allergens in siblings are similar.
