PG - 51-57 LID - S0378-1119(16)30196-2 [pii] LID - 10.1016/j.gene.2016.03.026 [doi] AB - BACKGROUND: sIL-6R is involved in a variety of inflammatory diseases. The present study analyzed the potential associations between two IL6R gene polymorphisms (rs2228145 and rs12083537) and asthma in a Han Chinese population. METHODS: A cohort of 394 patients and 395 healthy controls were genotyped to detect the two polymorphisms using SNaPshot. In 66 asthma patients and 49 controls, peripheral eosinophil and serum immunoglobulin E (IgE) levels were determined using a routine blood test, and sIL-6R levels were measured by ELISA. RESULTS: No statistically significant differences were detected between the patients and controls in the distribution of the two independent IL6R polymorphisms (p>0.05). However, rs2228145 C and rs12083537 G were significantly associated with decreased lung function in patients with asthma; the rs2228145 A-C variant was also associated with increased sIL-6R and IgE levels. In addition, sIL-6R levels were positively associated with IgE and inversely associated with lung function in patients with asthma. CONCLUSIONS: Our results provide evidence that rs2228145 C and rs12083537 G are associated with poor lung function in patients with asthma. Furthermore, the rs2228145 A-C variant is associated with levels of sIL-6R and IgE. CI - Copyright (c) 2016 Elsevier B.V. All rights reserved.
