Abstract:
ObjectiveTo investigate the effects of different amounts of iodine intake on the cellular and humoral immune in Grave's disease (GD) patients.MethodsThe clinical GD cases were diagnosed by thyroid fine needle Cytology examination.Patients in GD group are divided into GD group Ⅰ and GD group Ⅱ based on the median of urine iodine.The blood levels of FT4,FT3,TSH,TPOAb,TGAb,TRAb and TNF-t were detected.The difference and association of these parameters between these groups were analyzed.ResultsThe TNF-αt level in GD Ⅰ group was higher than that of GD Ⅱ group( P ＞ 0.05 ) ;The average level of TRAb of GD Ⅰgroup ( [ 1.4 ±0.2 ] U/L) were higher than that of GD Ⅱ group ( [ 1.2 ± 0.1 ] U/L) ( P ＜ 0.05 ) ;The positive rates of TGAb and TPOAb of GD Ⅰ group were higher than that of GD Ⅱ group ( P ＜ 0.05 ).The percentages of patients with high level of TGAb and TPOAb in GD Ⅰ group ( 78.9％ 、84.2％ ) were higher than that in GD Ⅱ group (50.0％,62.5％ ) ( x2 =6.79,10.70,P ＜0.05 ) ; Analysis showed a linear positive correlation of TNF-αwith TRAb and TPOAb ( r is 0.489 and 0.563,P ＜ 0.01 ).ConclusionIodine is an important factor to the development of Graves disease.Excessive iodine intake will exaggerate the GD condition and patients with GD should be controlled for iodine intake.
