Abstract:
Objective To investigate the influence of different time discontinuation of compound iodine solution on 131Ⅰ uptake and curative effect of 131Ⅰ therapy in patients with Graves disease (GD).Methods A total of 1 585 patients (415 males,1 170 females;age range:17-62 years) treated with 131Ⅰ therapy for the first time between January 2012 and November 2016 were enrolled in this retrospective study.All patients were divided into preliminary treatment group (n =85) and control group (no iodine solution taking,n =1 500).Preliminary treatment group including 4-7 d discontinuation subgroup (group A,n=35),8-14 d discontinuation subgroup (group B,n=28) and 15-30 d discontinuation subgroup (group C,n=22).The high-est radioactive iodine uptake (RAIU),effective half-life,free triiodothyronine (FT3) and free thyroxine (FT4) levels before 131Ⅰ therapy were compared,and curative effects were evaluated.One-way analysis of variance,Ridit analysis and x2 test were used to analyze the data.Results The highest RAIU in group A,group B,group C and control group was (64.86 ± 13.20) %,(67.40 ± 9.10) %,(73.46 ± 4.65) % and (74.14±9.87) %,respectively (F =1.658,P> 0.05).No significant difference was found in the effective half-life among 4 groups (F=0.651,P>0.05).FT3 level in group A and group B ((11.90±4.85) and (15.51±2.95) pmol/L) was significantly lower than that in control group ((23.98±4.98) pmoL/L) and group C ((22.08±2.31) pmol/L;F=13.972,t values:6.57-12.08,all P<0.05).FT4 level in group A and group B ((25.65±11.95) and (32.33±6.25) pmol/L) was obviously lower than that in control group ((73.65±21.55) pmol/L) and group C ((68.41±13.94) pmo]/L;F=21.238,t values:36.09-48.00,all P<0.01).The overall curative effect of preliminary treatment group and that of control group were not statistically significant (u=0.397,P>0.05),and no significant difference was found in the complete remission rates among 4 groups (x2 =1.169,P>0.05).Conclusions If pretreatment with compound iodine solution is used before 131Ⅰ therapy in GD,it is feasible to carry out 131Ⅰ therapy within 2 weeks after withdrawal.In order to avoid the possibility of severe hyperthyroidism after 131Ⅰ therapy,it is recommended that radioiodine treatment should be carried out after discontinuation for 4-7 d.
