Allergic reaction to insulin is known to be associated with eosinophilia and hyper IgE. Recent report showed that eosinophilia is related with the increased synthesis of galectin-9 (GAL-9) and osteopontin (OPN). Here, we examined plasma levels of GAL-9 and OPN first time in a case of 65-year old patient with insulin allergy. Insulin aspart & insulin aspart 30 mix were given to the patient and an elevation of the eosinophil count (8440/mul, 17.6 fold) and a moderate increase of IgE (501 U/ml, reference range: 10-350 U/ml), eotaxin-3 (168 pg/ml, 2 fold), histamine (0.95 ng/ml, 5.3 fold) were found 33 days later. The plasma levels of GAL-9 and OPN were 22.5 and 1.7 fold higher than the cut-off point, respectively. After one month cessation of insulin therapy, elevations of the eosinophil count (3,480/mul; 7.3 fold), and OPN (1.4 fold) still occurred but the GAL-9 levels became normal. Therefore, we noted the increases of GAL-9 and OPN in plasma for the first time in a patient with insulin allergy and propose that GAL-9 reflects the conditions of allergy more accurately.
已知对胰岛素的过敏反应与嗜酸性粒细胞增多和高IgE相关。最近的报告显示,嗜酸性粒细胞增多与半乳糖凝集素-9(GAL-9)和骨桥蛋白(OPN)合成增加有关。在此,我们首次检测了一名65岁胰岛素过敏患者的血浆GAL-9和OPN水平。给该患者注射门冬胰岛素和门冬胰岛素30混合注射液,33天后发现嗜酸性粒细胞计数升高(8440/μl,17.6倍),IgE适度增加(501 U/ml,参考范围:10 - 350 U/ml),嗜酸性粒细胞趋化因子-3(168 pg/ml,2倍),组胺(0.95 ng/ml,5.3倍)。血浆GAL-9和OPN水平分别比临界值高22.5倍和1.7倍。胰岛素治疗停止一个月后,嗜酸性粒细胞计数(3480/μl;7.3倍)和OPN(1.4倍)仍有升高,但GAL-9水平恢复正常。因此,我们首次在胰岛素过敏患者中发现血浆GAL-9和OPN升高,并提出GAL-9能更准确地反映过敏状况。
