Objective: To assess the implication of hepatitis C virus (HCV) infection in the development of autoimmune thyroid response, thyroid autoantibodies were studied in serum of HCV positive patients. Methods: Anti-microsomal, anti-thyroperoxidase (anti-TPO) and anti-thyroglobulin antibodies were evaluated in the sera of 100 patients with chronic hepatitis C (53 women and 47 men; mean age = 55±5 years). In parallel, thyroid autoantibodies were investigated in blood samples obtained from two separated control groups: age-matched HCV negative-HBV positive patients (25 women, 25 men; mean age= 47±6 years) and healthy blood donors (29 women and 21 men; mean age= 54±8 years). Results: Anti-thyroid antibodies were found more frequently in HCV positive women when compared to the men (8/53= 15.1% vs 0/47= 0%,.p<0.01).The prevalence of these autoantibodies was not statistically different between HCV positive and healthy female blood donors. However the investigation of thyroid autoantibody titers showed significantly higher levels of anti-TPO and anti-microsomal antibodies in HCV positive women in comparison with healthy women controls (respectively 1: 83200 vs 1: 1900 and 834 vs 23, p<0,01). Conclusions: This strong association between HCV infection and high levels of anti-thyroid autoantibodies in women outlines the interest of systematic detection of anti-microsomal and/or anti-TPO antibodies in this population. 相似文献

BACKGROUND AND OBJECTIVES: Auto-immune thyroid disease (AITD) has often been reported during interferon-alpha therapy for chronic viral C hepatitis (HCV) or other diseases. Recently, a high AITD prevalence has been reported in HCV independently on alpha-interferon therapy. The aim of our study is to investigate the possible relationship between AITD and HCV and HBV virus infections, and their influence on the thyroid function. MATERIAL AND METHODS: We prospectively studied 112 patients with AITD (94 women and 18 men; mean age: 49.8 +/- 14.9 yrs) and 88 patients with non-toxic goitre (NTG) (73 women and 15 men; mean age: 50.2 +/- 13.5 yrs) as controls. In all patients HCV antibodies, HBsAg and anti-HBs antibodies, TSH, FT3 and FT4 serum levels, circulating anti-thyroid-peroxidase antibodies (TPO-Ab) and anti-thyroglobulin antibodies (TG-Ab) were measured. RESULTS: HCV antibodies were positive in 11.6% of AITD patients (13/112) and in 2.3% of controls (2/88) (P < 0.05), the prevalence of HCV in the controls being similar to the expected value in the general population (about 2%). HBsAg and anti-HBs were found only in 2.6% of AITD patients (3/112) and 1.1% of controls (1/88) (P = NS), according to the expected value in the general population (about 2.5%). No difference in thyroid function was observed between positive and negative HCV subgroups. CONCLUSION: A significant association between HCV infection and AITD was found. This finding confirms that HCV, but not HBV, could be one of the environmental factors responsible for the breakdown of immunological tolerance. Therefore detection of TPO-Ab and TG-Ab in all HCV patients, independently of IFN therapy, is suggested and the utility of a screening for HCV in all AITD patients is stressed. 相似文献

Around 1-2% of pregnant women receive levothyroxine treatment for overt hypothyroidism. This condition, which commonly has an autoimmune cause, is defined as a low plasma free thyroxine (T4) concentration and a raised plasma thyroid-stimulating hormone (TSH) concentration. Around another 2.5% of pregnant women have subclinical ('compensated') hypothyroidism, which is defined as a raised plasma TSH concentration with a normal free T4 concentration. Here we review the evidence on whether such problems affect pregnancy outcome or the offspring and update our previous advice on the management of hypothyroidism in pregnancy; we do not cover postpartum thyroid disorders. 相似文献

We treated 26 hypothyroid women - 11 with autoimmune thyroiditis and 15 who had been treated for thyroid cancer - with their usual dose of thyroxine (T4) or with a regimen in which 50 &mgr;g of T4 had been replaced by 12.5 &mgr;g of triiodothyronine (T3). Patients were first randomly assigned to one regimen for 5 wk and then to a second regimen for an additional 5 wk. The substitution of T3 for a portion of T4 caused expected changes in concentrations of thyroid hormones and thyroid-stimulating hormone (TSH). After combined hormone treatment there were clear improvements in both cognition and mood, the latter changes being greater. The patients who had been treated for thyroid cancer showed more mental improvement than the women with autoimmune thyroiditis, perhaps because they were more dependent on exogenous hormone. Some mood improvements correlated positively with changes in TSH while others correlated negatively with changes in free T4. 相似文献

甲状腺疾病是一组比较复杂的内分泌疾病,用于该疾病检测的实验室项目也日益增多,今天我们主要讨论甲状腺过氧化物酶抗体在我院临床诊断甲状腺类疾病的应用。甲状腺过氧化物酶(TPO)是位于甲状腺上皮细胞的顶端细胞膜上,直接参与甲状腺细胞中的氧化酪氨酸的碘化及碘化酪氨酸的偶联等。它是甲状腺激素合成过程中的关键酶。TPO 也是自身免疫性甲状腺疾病的(AITD)一种重要的自身抗原,可以刺激机体免疫系统产生TPO抗体(TPO-Ab)。TPO-Ab作为AITD一种主要的自身抗体,可通过激活补体,抗体依赖细胞介导的细胞毒作用和致敏的T杀伤细胞直接杀伤等作用机制,引起甲状腺滤胞损伤,间接的抑制甲状腺的合成,导致甲状腺功能减退的主要机制。所以TPO-Ab水平的检测是诊断AITD的一项不可缺少的实验室指标。 相似文献

One hundred and twenty-one patients with HCV-related chronic hepatitis and normal baseline thyroid function were studied. Forty-six patients received IFN alpha-2b, while 75 patients had Peg-IFN alpha-2b with ribavirin more recently. Thirty patients (ten belonging to the standard IFN group) were re-treated. The pre-treatment prevalence of thyroid antibodies was 3.3%. At the end of the first antiviral treatment, the prevalence of laboratory alterations (presence of antibodies and abnormal hormonal levels) of thyroid was assessed to be 20.7% (25 patients), being quite similar for standard-interferon- and pegylated-interferon-treated patients (P = 0.63). TSH level alteration was seen in eleven patients (9.1% of the overall population and 44% of the antibodies positive patients), of whom ten were females. The anti-microsomal, anti-thyroperoxidase and anti-thyroglobulin antibodies, in combined or isolated presence, were detected in all 25 patients. During the re-treatment we noticed worsening only of previous thyroid abnormalities. No patient changed the antiviral schedule after the emerging of thyroid alterations. All eleven patients remained thyroid dysfunctional at the end of the follow-up (ten with Hashimoto's thyroiditis and one with Graves disease), meanwhile the near totality of patients with presence of antibodies remained positive. Interestingly, eight out the 14 patients who showed mood disorders after antiviral therapy, belonged to the aforementioned cohort. 相似文献

Hashimoto thyroiditis (HT) is one of the autoimmune diseases of the thyroid gland. It is characterized by diffuse lymphocytic infiltration of the thyroid gland and the elevated levels of the serum anti-thyroid antibodies. Recently Hashimoto thyroiditis has been proposed as a systemic disorder. Acute-phase reactans have been implicated for their involvement as pro-inflammatory molecules in various inflammatory diseases. The aim of the present study was to examine the blood concentrations of acute-phase proteins, namely C-reactive protein (CRP), serum amyloid A (SAA) and fibrinogen in the patients with Hashimoto thyroiditis. Two groups were enrolled: study group consisting from euthyroid patients with HT (n=30), and healthy control subjects (n=30). Blood samples were obtained from all the patients and control subjects and were analyzed for serum CRP, SAA, fibrinogen, and ESR. Mean ESR was found to be higher in HT patients than control group (p=0.024). The mean fibrinogen and SAA values in HT were also significantly higher than that of the control group (p=0.03, p=0.002). We therefore suggest that a low-grade systemic inflammation may exist in HT patients even if they were euthyroid. 相似文献

OBJECTIVES: To determine the prevalence of thyroid auto-antibodies in specimens sent to Parirenyatwa hospital laboratory for thyroid function testing and to compare the thyroid status of these patients with that of apparently healthy subjects. DESIGN: Cross sectional study. SETTING: Immunology and radio-immunoassay laboratories, Parirenyatwa hospital, Department of Chemical Pathology, and Blood Transfusion Services, Harare. SUBJECTS: 212 blood samples submitted for thyroid function testing and 230 blood samples from apparently healthy blood donors. MAIN OUTCOME MEASURES: Serum concentrations of free triiodothyronine (FT3), thyroxine (FT4), thyrotropin (TSH), and thyroid auto-antibodies; anti microsomal (M Ab) and antithyroglobulin (Ag Ab) antibodies. RESULTS: The hyperthyroid subjects had median serum TSH level of 0.027 mIU/L (Q1 = 0.006, Q3 = 0.052), median serum FT3 level of 15.895 pmol/L (Q1 = 10.563; Q3 = 30.111), and a median serum FT4 level of 45.513 pmol/L (Q1 = 30.256; Q3 = 63.910). The goitrous subjects had median serum TSH level of 0.390 mIU/L (Q1 = 0.157; Q3 = 0.745). The blood donor group had median TSH value of 0.724 mIU/L (Q1 = 0.471; Q3 = 1.170). (Normal ranges: TSH = 0.167 to 2.80) Amerlite TSH-30 diagnostic kit; FT3 = 3.4 to 7.2 pmol/L; FT4 = 11 to 24 pmol/L) Amelex-MAB diagnostic kits) Thirty nine percent of the hyperthyroid subjects had either positive M Ab or Tg Ab or both. None of the goitrous subjects and the blood donors tested positive for neither M Ab, nor Tg Ab. No significant difference was found between the blood donors and the goitrous subjects for serum FT4 (P = 0.51). However, significant differences were found between the goitrous, the blood donor and the hyperthyroid groups with regards to serum TSH, serum FT4, and serum FT3 levels (p = 0.001). CONCLUSION: Our findings indicate that the occurrence of thyroid auto-antibodies among the blood donors and the goitrous population was uncommon, but high in the hyperthyroid subjects. The increase of iodine intake through iodine prophylaxis could have had the side effects of iodine induced hyperthyroidism. 相似文献

Objective:To investigate the effect of levothyroxine (LT4) therapy on urinary albumin excretion rate (UAER) in early type 2 diabetic nephropathy (DN) and subclinical hypothyroidism (SCH) patients with mildly increased thyroid stimulating hormone (TSH) levels and serum thyroid peroxidase antibody (TPO-Ab) positivity.Methods:Application of randomized double-blind and placebo-controlled methods. A total of 136 normotensive patients with early type 2 DN and SCH (TSH 4.0–7.0 mIU/L and TPO-Ab positive) were selected, and were randomly divided into two groups for LT4 or placebo treatments, respectively. Changes in UAER, serum creatinine, glomerular filtration rate (GFR), blood pressure, serum uric acid and lipids in patients before and after 48 weeks of treatment were examined and compared between groups.Results:There were no statistically significant differences in the baseline characteristics of study participants between two treatment groups (p?>?0.05 for all). After 48 weeks of treatment, compared to the placebo treatment, the LT4 treatment was more effective in reducing total cholesterol (p?0.05). Further comparison of therapy-related differences between groups showed that the LT4 treatment was better in reducing UAER, low-density lipoprotein cholesterol and uric acid than the placebo group (p?0.01 for all).Conclusion:The LT4 treatment may decrease UAER and exert kidney protection effects in early type 2 DN and SCH patients with mildly increased TSH levels and serum TPO-Ab positivity. However, due to the short duration of follow-up and small number of cases, the results of this study need future trials with larger numbers of patients and longer follow-up periods to verify whether such a strategy can provide durable benefits. 相似文献

PURPOSE: Hepatitis B vaccine has been postulated as a possible cause of autoimmune disorders, including autoimmune thyroid diseases (ATD). Cases of Graves' disease and Hashimoto's thyroiditis, following hepatitis B vaccine have been reported to the Vaccine Adverse Events Reporting System (VAERS). To test the hypothesis that hepatitis B vaccine increases the risk of ATD, we conducted a case-control study, within the Vaccine Safety Datalink project. METHODS: We identified potential cases of Graves' disease and Hashimoto's thyroiditis, among persons aged 18-69 years from administrative data recorded by three health maintenance organizations (HMOs) and verified cases by medical record review. Controls were frequency-matched to cases by birth year, sex, and study site. Vaccine information was collected from administrative records, chart review, and telephone interviews with study subjects. We enrolled 355 Graves' disease cases, 418 Hashimoto's thyroiditis cases, and 1102 controls. We assessed the association between ever-receipt of hepatitis B vaccine, as well as receipt of hepatitis B vaccine less than 1 year, 1-5 years and at least 5 years prior to the index date, and the risk of ATD. RESULTS: Ever-receipt of hepatitis B vaccine was not associated with risk of Graves' disease (odds ratio (OR), 0.90; 95% confidence interval (CI), 0.62-1.32) or Hashimoto's thyroiditis (OR, 1.23; 95%CI, 0.87-1.73). There was also no association between the time interval since receipt of hepatitis B vaccination and either outcome. CONCLUSIONS: We did not observe an increased risk of Graves' disease or Hashimoto's thyroiditis, following receipt of hepatitis B vaccine. 相似文献
