However its curative effect is influenced by many factors, therefore there are some difficulties for doctors to establish individual treatment strategy. The aims of this study were to determine the incidence of early and late hypothyroidism after 131Ⅰ treatment for Graves＇ disease （GD） and to compare their correlation, to observe and analyze the influential factors and to understand the predictabilities of them.Methods Five hundred GD patients （144 males, 356 females; age （41.2±12.3） years） received 131Ⅰ treatment for the first time. The therapeutic procedure was carried out as the following： undergoing 131Ⅰ uptake test to obtain maximum of thyroid uptake value and effective half-life （EHL） time; estimating the thyroid＇s weight by ultrasonography; determination of thyroid hormones and correlative antibodies; pre-therapy physical examination; thyroid imaging; calculating 131Ⅰtherapeutic dosage; per os uptake of the determined 131Ⅰ dosage; follow-up appraisal of curative effect. The observing parameters included age, gender, thyroid weight, GD duration, condition of onset, state of disease, course of treatment, EHL time, maximum of thyroid uptake value, 131Ⅰ dosage and titer of correlative antibodies. We sorted out the data and used both univariate and multivariate analysis to evaluate them statistically.Results The incidence rates of early and late hypothyroidism were 33.2% and 6.6% respectively after 131Ⅰ treatment and approximately 22.2% cases of late hypothyroidism developed from early hypothyroidism. The influential factors of early hypothyroidism included course of GD, the highest thyroid uptake ratio of 131Ⅰ, EHL time and thyroid microsome antibody （TMAb）, etc. A multivariate analysis on late hypothyroidism showed that female patients, with recurrence after anti-thyroid drug treatment and higher thyroid weight, had l展开更多

METHODS: We investigated 112 consecutive Caucasian patients (48 females and 4 males with Graves' disease and 54 females and 6 males with Hashimoto' s thyroiditis HT), at their first diagnosis of ATDs. We tested for H. pylori in stool samples using an amplified enzyme immunoassay and Cag-A in serum samples using an enzyme-linked immunoassay method (ELISA). The results were analyzed using the two-sided Fisher' s exact test and the respective odds ratio (OR) was calculated. RESULTS: A marked correlation was found between the presence of H. pylori (P ≤ 0.0001, OR 6.3) and, in particular, Cag-A positive strains (P ≤ 0.005, OR 5.3)in Graves' disease, but not in Hashimoto's thyroiditis, where we found only a correlation with Cag-A strains (P ≤ 0.005, OR 8.73) but not when H. pylori was present. CONCLUSION: The marked correlation between H. pylori and Cag-A, found in ATDs, could be dependent on the different expression of adhesion molecules in the gastric mucosa.展开更多

Methods: Thirty-three patients with ophthalmopathy of Graves’ disease, fifty-six Graves’ patients without ophthalmopathy and sixty normal subjects as control were involved in the present case-control study. The polymorphisms were evaluated by polymerase chain reaction fragment length polymorphism (PCR-RFLP). Com-parisons were made of gene frequencies and allele frequencies between the groups. Results: The gene frequencies of CT and allele frequencies of T were much higher in Graves’ patients with ophthalmopathy than that in the group without ophthalmopathy (P=0.020, P=0.019). The gene frequencies of GG and allele frequencies of G in patients with Graves’ disease were significantly increased as compared with control group (P=0.008, P=0.007). The data suggest that smokers with Graves’ disease seemed to be more predisposed to ophthalmopathy than non-smokers (P=0.018). Conclusion: Our results suggest that an allele of T at position –318 of promoter is associated with genetic susceptibility to Graves’ ophthalmopathy while an allele of G at position 49 of exon 1 is associated with genetic susceptibility to Graves’ disease instead. Smoking is believed to be a major risk factor for ophthalmo-pathy.展开更多

Approved by the local institutional review board（IRB）, 106 consecutive patients with GO were included in this prospective study. All subjects were divided into two groups according to the patients＇ clinical activity score（CAS）： the CAS positive group（CAS ≥3） or the CAS negative group（CAS 〈3）. T2 relaxation time of extraocular muscles（T2RT; ms） and the areas of four extra-ocular muscles（AEOMs; mm2） were measured by 3D T2-mapping MR sequence before and after methylprednisolone treatment, so as the CAS and some ophthalmic examinations including visual acuity, intra-ocular pressure, eyeball movement, diplopia and proptosis. In addition, 24 healthy volunteers were recruited as the control group. The mean T2RT and AEOMs in CAS positive group were higher than those in CAS negative group. Both CAS positive and negative groups had significantly higher mean T2RT and AEOMs than the control group（P〈0.01）. There was a positive correlation between T2RT and AEOMs values in GO patients, both of them had a positive correlation with CAS and the ophthalmic examinations. It was concluded that to evaluate the activity of GO, CAS was mostly related to inflammation symptoms of ocular surface, more than that, T2RT and AEOMs were also related to abnormal findings of the ophthalmic examinations including high ocular pressure, impaired eyeball movement, diplopia and proptosis. T2RT and AEOMs can reflex the inflammation state of ocular muscles better. CAS combined with 3D T2-mapping MR imaging could improve the sensitivity of detection of active GO so as the prediction and evaluation of the response to methylprednisolone treatment.展开更多

Patients were divided into 4 groups as medial-inferior, mediallateral（balanced）, medial-lateral-inferior, and lateral only according to the applied surgical technique. Surgical indications, regression degrees on Hertel exophthalmometer, new-onset diplopia in the primary gaze and new-onset gaze-evoked diplopia after surgery and visual acuity in cases with dysthyroid optic neuropathy（DON） were compared between different surgical techniques.RESULTS： The study included 248 eyes of 149 patients. The mean age for surgery was 42.3±13.2 y. DON was the surgical indication in 36.6% of cases, and three-wall decompression was the most preferred technique in these cases. All types of surgery significantly decrease the Hertel values（P〈0.005）. Balanced medial-lateral, and only lateral wall decompression caused the lowest rate of postoperative new-onset diplopia in primary gaze. The improvement of visual acuity in patients with DON did not significantly differ between the groups（P=0.181）. CONCLUSION： The study show that orbital decompression surgery has safe and effective long term results for functional and cosmetic rehabilitation of GO. It significantly reduces Hertel measurements in disfiguring proptosis and improves visual functions especially in DON cases.展开更多

In the present study, we conducted a meta-analysis to examine this association. Two reviewers systematically searched eligible studies in Pub Med, Web of Science, Embase and China Biomedical Literature Database（CBM）. A meta-analysis on the association between GD and TSHR intron 1 rs179247 or rs12101255 was performed. The odd ratios（OR） were estimated with 95% confidence interval（CI）. Meta package in R was used for the analyses. Seven articles（13 studies） published between 2009 and 2014, involving 5754 GD patients and 5768 controls, were analyzed. The polymorphism of rs179247 was found to be associated with an increased GD risk in the allele analysis（A vs. G： OR=1.40, 95% CI=1.33–1.48） and all genetic models（AA vs. GG： OR=1.94, 95% CI=1.73–2.19; AA＋AG vs. GG： OR=1.57, 95% CI=1.41–1.74; AA vs. AG＋GG： OR=1.54, 95% CI=1.43–1.66）. The site rs12101255 also conferred a risk of GD in the allele analysis（T vs. C： OR=1.50, 95% CI=1.40–1.60） and all genetic models（TT vs. CC： OR=2.22, 95% CI=1.92–2.57; TT＋TC vs. CC： OR=1.66, 95% CI=1.50–1.83; TT vs. TC＋CC： OR=1.74, 95% CI=1.53–1.98）. Analysis of the relationship between rs179247 and Graves＇ ophthalmopathy（GO） showed no statistically significant correlation（A vs. G： OR=1.02, 95% CI=0.97–1.07）. Publication bias was not significant. In conclusion, GD is associated with polymorphisms of TSHR intron 1 rs179247 and rs12101255. There is no association between rs179247 SNPs and GO.展开更多

Electronic databases were searched, and standard methodological guidance of Cochrane Handbook for Systematic Reviews of Interventions was used. The primary outcome was overall response, and secondary outcomes included the improvement and change in clinical activity score(CAS), and adverse events.RESULTS: Ten RCTs were included in the Meta-analysis. Low quality evidence(one trial) showed that participants receiving IVGC achieved significantly higher response compared to participants receiving placebo [risk ratio(RR) 7.50, 95% confidence interval(CI) 1.14 to 49.26]. Moderate quality evidence(four trials) support appreciable benefit of IVGC in response compared with oral glucocorticoids(OGC), with of RR being 1.51(95%CI 1.25 to 1.83). There was low quality evidence(one trial) compatible with appreciable benefit for IVGC plus orbital radiotherapy in response(RR 1.38, 95%CI 1.07 to 1.79), compared with OGC plus orbital radiotherapy. One IVGC versus rituximab trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lowerresponse compared to participants using rituximab(RR 0.70, 95%CI 0.50 to 0.98). One IVGC versus mycophenolate mofetil(MMF) trial provided moderate quality evidence suggesting that participants using IVGC achieved significantly lower response compared to participants using MMF(RR 0.74, 95%CI 0.63 to 0.88). Very low quality evidence(one trial) showed that participants with dysthyroid optic neuropathy(DON) receiving IVGC were more likely to achieve response compared to participants receiving orbital decompression(RR 3.33, 95%CI 0.51 to 21.89).CONCLUSION: The current evidence is moderate quality, which is sufficient to support IVGC to be as the first-展开更多
