Expression of galectin-13 in allergic diseases involving airway, skin and mucous membranes

Abstract

To detect the expression of galectin-13 in allergic diseases and provide a new way for the diagnosis and treatment of allergic diseases. A retrospective analysis method was used to screen 216 patients with allergic diseases with house dust mites or aspergillus as allergens who visited the Department of Allergy and Department of Respiratory of Tongji Hospital attached Tongji Medical College, Huazhong University of Science and Technology from March 2018 to May 2021. These allergic diseases included allergic asthma, allergic bronchopulmonary aspergillosis, allergic rhinitis, allergic conjunctivitis, atopic dermatitis, allergic urticaria. 25 subjects without underlying diseases were selected as healthy controls. The galectin-13 content in serum in each group were detected, and the Pearson correlation was used to determine the correlation between the galectin-13 content in serum in each group and blood eosinophil count, blood specific IgE, the score scale of allergic disease. The expression of Galectin-13 was increased in allergic asthma group (71.44±39.44) pg/ml, allergic bronchopulmonary aspergillosis group (100.10±47.62) pg/ml, allergic rhinitis group (54.11±24.81) pg/ml and dermatitis group (44.12±19.51) pg/ml. The expression of galectin-13 was not significantly increased in allergic urticaria group (32.75±10.29) pg/ml and the allergic conjunctivitis group (30.55±9.87) pg/ml. The galectin-13 content in serum, was positively correlated with blood eosinophil count(rs=0.54, P<0.001) and house dust mite specific IgE (rs=0.51, P<0.001) in allergic asthma group, and was positively correlated with blood eosinophil count(rs=0.63, P=0.025) and aspergillus fumigatus specific IgE (rs=0.58, P=0.046) in allergic bronchopulmonary aspergillosis group. It was positively correlated with blood eosinophil count (rs=0.52, P=0.000 2) and house dust mite specific IgE (rs=0.41, P=0.005) in allergic rhinitis group. In allergic conjunctivitis group, the expression of galectin-13 was positively correlated with conjunctivitis symptom score (rs=0.47, P=0.048). In atopic dermatitis group, the expression of galectin-13 was positively correlated with blood eosinophil count (rs=0.58, P<0.001) and house dust mite specificity IgE (rs=0.47, P=0.002). In allergic urticaria group, the expression of galectin-13 was not significantly correlated with blood eosinophil count or house dust mite specific IgE. Galectin-13 may be related to the occurrence and progress of allergic diseases and may be involved in the occurrence of eosinophilic inflammation.
