Abstract:
Objective To explore the relationship of autoantibodies against G protein coupled angiotensin Ⅱ-1 receptor (AT1 R),α1-adrenergic and β1-adrenergic receptors (α1 R and β1 R) with thyrotoxicosis heart disease (THD).Methods The epitopes of the second extracellular loop ofAT1 R (165-191),α1 R (192-218),and β1 R(197-222) were synthesized for screening autoantibodies from 277 participants by ELISA.237 patients with thyrotoxicosis were subdivided into thyrotoxicosis treatment group (n =148) and thyrotoxicosis recovery group (n =89),or into THD group (n =46) and simple hyperthyroidism group (n =191).40 healthy subjects were served as control group.Results (1) The positive rates of autoantibodies against AT1 R,α1 R and β1 R in thyrotoxicosis patients were higher than those in the control subjects (31.6％ vs 12.5％,27.8％ vs 10.0％,and 23.6％ vs 7.5％,all P＜0.05).The positive rates of the three autoantibodies in the patients with Graves' disease were higher compared with thyrotoxicosis caused by other reasons (36.3％ vs 19.7％,32.2％ vs 16.7％,and 28.1％ vs 12.1％,all P＜0.05).(2) In thyrotoxicosis treatment group,the positive rates of autoantibodies against AT1 R and α1 R were higher than those in the hyperthyroidism recovery group (40.5％ vs 16.9％ and 33.1％ vs 19.1％,both P＜0.05).(3) The incidence of autoantibodies against AT1 R and α1 R in THD were significantly higher compared with simple hyperthyroidism (52.2％ vs 26.7％ and 43.5％ vs 24.1％,both P＜0.05).Conclusions Autoantibodies against AT1 R,α1 R,and β1 R may play important roles in the pathogenesis of hyperthyroidism,which may be involved in the progression of THD.
