ABSTRACT
Objective:To learn about the fasting blood glucose (FBG) level of adults in different water iodine areas in Shanxi Province, and to study the relationship between high iodine intake in drinking water and blood glucose.Methods:The urinary iodine content and FBG of 18-65 years old residents in the high-water iodine area of Gaoche Village, Wenshui County, Shanxi Province in 2016 (iodine content in drinking water > 100 μg/L) and the low-water iodine area of Maxi Village (iodine content in drinking water < 10 μg/L) were retrospectively analyzed, and the urinary iodine content, FBG level and its abnormal rate of adults in different water iodine areas were compared.Results:A total of 598 subjects were included, including 276 in Gaoche Village and 322 in Maxi Village. The difference of median urinary iodine (422.8, 126.5 μg/L) between Gaoche Village and Maxi Village was statistically significant ( Z = 7.81, P < 0.001). The FBG levels of adults in Gaoche Village and Maxi Village [(6.70 ± 1.87), (6.04 ± 1.23) mmol/L] were significantly different ( t = 5.18, P < 0.001). The difference of FBG level in males [(6.82 ± 1.82), (5.99 ± 1.11) mmol/L] between the two regions was statistically significant ( t = 4.45, P < 0.001), the difference of FBG level in females [(6.59 ± 1.91), (6.07 ± 1.30) mmol/L] was statistically significant ( t = 2.96, P = 0.003). In Gaoche Village and Maxi Village, there was no statistically significant difference in FBG level between males and females ( t = 1.04, 0.52, P = 0.308, 0.564). Comparison of FBG levels in 18-< 45 years old group [(6.31 ± 1.57), (5.79 ± 0.89) mmol/L] and 45-65 years old group [(7.00 ± 2.02), (6.18 ± 1.36) mmol/L] between the two regions, the differences were statistically significant ( t = 3.10, 4.60, P = 0.002, P < 0.001). Moreover, in Gaoche Village and Maxi Village, the FBG level of the 45-65 years old group was higher than that of the 18-< 45 years old group in the same area, and the difference was statistically significant ( t = 3.07, 2.74, P = 0.003, 0.006). The abnormal rate of FBG in adults in Gaoche Village and Maxi Village [28.3% (78/276) and 15.5% (50/322)] was statistically significantly different (χ 2 = 14.32, P < 0.001). Conclusion:Long-term intake of high iodine in drinking water may cause abnormal glucose metabolism.
ABSTRACT
Objective:To investigate the prevalence of thyroid disease in adults in different water iodine areas and to explore the association between iodine and thyroid disease.Methods:In May of 2016, using cross-sectional survey, Gaoche Village and Maxi Village of Wenshui County were selected in Shanxi Province as a high-iodine area and a low-iodine area, respectively, Xiwenzhuang Village of Taiyuan City as an appropriate-iodine area. Questionnaire surveys, urinary iodine levels, thyroid ultrasound, determination of thyroid function and autoantibody were conducted for permanent residents aged 18 - 65.Results:A total of 898 people were investigated, including 288 in high-iodine area, 324 in low-iodine area and 286 in appropriate-iodine area. The medians urinary iodine were 417.8, 126.6 and 216.5 μg/L in high, low and appropriate-iodine areas, respectively, and the difference was statistically significant ( H = 288.61, P < 0.05). After age and sex standardization, the detection rates of hyperthyroidism in low, appropriate and high-iodine areas were 0.27%, 1.06% and 1.43%, respectively. The detection rates of sub-clinical hyperthyroidism were 0.57%, 0.31% and 0.30%, respectively. The detection rates of hypothyroidism were 1.45%, 1.15% and 1.85%, respectively. The detection rates of sub-clinical hypothyroidism were 19.34%, 28.50% and 32.76%, respectively. The detection rates of thyroid nodule were 20.51%, 20.17% and 33.78%, respectively. The positive rates of anti-thyroglobulin antibodies (TgAb) were 18.13%, 19.41% and 11.99%, respectively. The positive rates of thyroid peroxidase antibody (TPOAb) were 9.25%, 12.04% and 8.97%, respectively. The appropriate-iodine area was used as control, logistic regression analysis showed that only the detection rate of thyroid nodule in high-iodine area was significantly higher than that in appropriate-iodine area [odds ratio ( OR) = 0.488 5, 95% confidence interval ( CI) = 0.327 2 - 0.729 2 , P < 0.05]. Conclusion:In Shanxi Province, the detection rate of thyroid nodules is different in different areas of water iodine, and the detection rate of thyroid nodule in adults in high-iodine area is higher than that in other areas.
ABSTRACT
Objective:To study the relationship between thyroid volume (TV) and thyroid autoantibodies in patients with autoimmune thyroid disease (AITD), and to explore the factors affecting goiter in patients with AITD.Methods:The newly diagnosed AITD adult patients in the Affiliated Hospital of Shanxi Institute for Endemic Disease Prevention and Control from November 2019 to October 2020 were selected for questionnaire survey, physical examination, thyroid function and thyroid autoantibody test, determination of serum iodine content and thyroid ultrasound, and the correlation between thyroid volume and thyroid autoantibody was analyzed.Results:A total of 147 newly diagnosed adult AITD patients were included, including 63 cases of Graves' disease (GD, 30 males and 33 females) and 84 cases of chronic lymphocytic thyroiditis (HT, 29 males and 55 females). The TV of male and female patients with GD was positively correlated with the levels of thyrotropin receptor antibody (TRAb) ( rmen = 0.515, rwomen = 0.412, P < 0.05). The TV of male and female patients with HT was not correlated with the levels of thyroid peroxidase antibody (TPOAb) and thyroglobulin antibody (TGAb, rmen = - 0.137, 0.168, rwomen = 0.184, - 0.088, P > 0.05). There were no correlation between TPOAb levels and TGAb levels in male and female HT patients ( rmen = 0.153, rwomen = 0.102, P > 0.05). The TV of male and female patients with GD or HT was not correlated with the serum levels of iodine ( rmen = 0.230, 0.013, rwomen = 0.096, 0.069, P > 0.05). Conclusion:TRAb level is positively correlated with the TV in GD patients.
ABSTRACT
Objective:To master the prevalence of thyroid nodule in adults in different water iodine areas and to explore the association between high iodine intake through drinking water and thyroid nodule prevalence.Methods:Xiwenzhuang Village of Taiyuan City was selected as iodine-adequate area, and Gaoche Village and Maxi Village of Wenshui County as high-iodine area and low-iodine area, respectively, in Shanxi Province. Questionnaire surveys were conducted, thyroid ultrasound was used and urinary iodine levels were determined of residents aged 18 to 65 years. Analysis of the prevalence of thyroid nodules in adults in different wated iodine areas.Results:A total of 868 person were investigated, including 286 in high-iodine area, 270 in iodine-adequate area and 312 in low-iodine area. The medians urinary iodine in high, adequate and low iodine areas were 418.7, 218.5 and 127.1 μg/L, respectively, and the differences were statistically significant ( H = 289.70, P < 0.05). The detection rate of thyroid nodule in adults with high, adequate and low iodine levels were 31.1% (89/286), 27.4% (74/270) and 19.2% (60/312), respectively, the differences were significant statistically among three groups (χ 2 = 11.65, P < 0.05). The detection rates of solitary nodule in adults were 17.8% (51/286), 14.1% (38/270), and 13.1% (41/312), respectively, the differences were not significant statistically among the three groups (χ 2 = 2.83, P > 0.05). The detection rate of multiple nodules in adults were 13.3% (38/286), 13.3% (36/270), and 6.1% (19/312), respectively, the differences were significant statistically among the three groups (χ 2 = 10.89, P < 0.05) high-iodine area and iodine-adequate area have higher detection rates than low-iodine area ( P < 0.05). The thyroid nodules were mainly the cyst nodules in high-iodine area. Conclusions:The detection rate of thyroid nodule in adults is the lowest in adequate iodine nutrition level. More iodine intake is probably a risk factor for thyroid multiple nodules.
ABSTRACT
Objective To evaluate the efficacy and safety of steroids-free immunosuppressive therapy including tacrolimus, cyclosporin A, tripterygium glycosides or intravenous cyclophosphamide in membranous nephropathy (MN) patients combined with type 2 diabetes mellitus (T2DM). Methods This study was a retrospective analysis of patients with T2DM complicated with biopsy proved MN in the First Affiliated Hospital, College of Medicine, Zhejiang University from January 2009 to January 2017. The patients were divided into steroids-free group and control group. The patients in steroids-free group were treated with one or two immunosuppressive agents except glucocorticoids. The patients in control group were treated with glucocorticoid combining with immunosuppressive agents. Results A total of 64 patients were enrolled in this study. There were 26 cases in steroids-free group and 38 cases in control group. The total remission rate was 69.24％ in steroids-free group and 73.68％ in control group at 12 months. In a median follow up of 33(12-106) months, two patients in control group entered hemodialysis and one of them died after 1 year of dialysis. One patient in steroids-free group died of accidental death and no patient entered dialysis. All patients in control group had elevated blood glucose level, whereas only 5 patients in steroids-free group had elevated blood glucose and all these 5 patients used tacrolimus. Conclusion Immunosuppressive regimen without glucocorticoid treatment can reduce side effects on blood glucose level in MN patients with type 2 diabetes, with a certain rate of treatment response.
