Abstract Conflicting results have been reported regarding serum lipoprotein(a) (Lp(a)) concentrations in patients with hypothyroidism. We addressed the question whether thyroid autoimmunity could be associated with elevated Lp(a) values independent of the thyroid status. Lp(a) was measured by ELISA in 30 males, 29 premenopausal and 30 postmenopausal females positive for thyroid peroxidase- and/or thyroglobulin-antibody (T-Abs) and normolipidemic, screened out respectively from 428 male donors, 162 premenopausal donors and 108 postmenopausal females; they were compared with 65 males, 72 premenopausal and 48 postmenopausal females, negative for thyroid antibodies, normolipidemic and matched for age. T-Abs-positive male donors showed serum Lp(a) concentrations significantly increased compared with males without T-Abs (mean 19·7 ± 15·9 vs 12·7 ± 17·5 mg/dl; median 17·0 vs 4·0 mg/dl; Mann Whitney U test: P = 0·0000). In premenopausal females no difference could be found between T-Abs-positive and T-Abs-negative subjects (mean 13·2 ± 16·1 vs 12·3 ± 13·9 mg/dl; median 5·2 vs 8·7 mg/dl), suggesting an Lp(a) lowering effect of estrogens. The study was, therefore, extended to postmenopausal females. Significantly elevated Lp(a) levels were found in 30 postmenopausal females with T-Abs when compared with 48 postmenopausal females without T-Abs (40·0 ± 34·2 mg/dl vs 20·7 ± 19·3 mg/dl; median 32·0 vs 18·0 mg/dl; Mann Whitney U test: P = 0·0002). Finally, 21 postmenopausal, normolipidemic, autoimmune hypothyroid patients on l-thyroxine and euthyroid compared with 48 postmenopausal females without T-Abs also showed increased serum levels of Lp(a) (mean 27·0 ± 16·8 mg/dl vs 20·7 ± 19·3 mg/dl, median 25·0 vs 18 mg/dl; Mann Whitney U test: P = 0·0024). Thyrotropin levels in all subjects and patients were within the normal range. In conclusion, our results in males and postmenopausal females with T-Abs and euthyroid show an association between thyroid autoimmunity and increased levels of Lp(a), while the results obtained in premenopausal females suggest that estrogens might interfere with the Lp(a) increase related to thyroid autoimmunity.

Background: Thyroid autoimmunity is more common in females than in males. One possible explanation for this female preponderance may be the effect of oestrogens on the immune system. It has also been suggested that foetal microchimerism involving transfer of foetal cells into maternal tissue during pregnancy may play an important role. Objective: We investigated the association between the presence of circulating thyroid autoantibodies and previous pregnancy, parity and the use of oral contraceptives (OCs) and hormone replacement therapy (HRT) in a population cohort. Methods: We examined 3712 women randomly selected from the general population. Serum was analysed for thyroid peroxidase antibody (TPO-Ab) and thyroglobulin antibody (Tg-Ab) using assays based on an RIA technique (DYNO test). Data were analysed in logistic regression models to adjust for possible confounders. Women previously treated for thyroid disease or with pregnancy within 1 year prior to the study were excluded from the analyses. Results: In both univariate and multivariate models and whether the presence of TPO-Ab and Tg-Ab was investigated alone or in combination, findings were negative with respect to an association between circulating thyroid antibodies and previous pregnancy, number of pregnancies, parity and previous abortion. There was no association between thyroid autoantibodies and use of OCs. Women aged 60–65 years receiving HRT now or previously had a lower prevalence of Tg-Ab (univariate, P = 0.01; multivariate, P = 0.02). No such association was observed between HRT and TPO-Ab. Conclusion: In this population study there was no association between previous pregnancy, parity and thyroid antibodies, which argues against the role of microchimerism as a trigger of thyroid autoimmunity. Exogenous oestrogens may reduce aspects of autoimmunity.

IntroductionAlthough autoimmune thyroid disease is less common in males, it is unclear whether estrogen contributes to the difference in susceptibility among males.ObjectiveTo examine whether circulating estradiol (E2) is related to thyroid autoimmunity in males.Patients and methodsOne-thousand two-hundred and sixty-three males aged 15–94 years were studied. Serum levels of E2, TSH receptor antibody (TRAb), thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TgAb), free thyroxine (FT4), and TSH were measured by ELISA.ResultsCirculating E2varied widely in males, ranging 18.4–403.7 pmol/l with a mean value of 136.2±51.7 pmol/l. E2increased with age (r=0.18,P<0.001). No relationship between E2and BMI was found. When comparing the difference in E2according to the test results of TRAb, TPOAb, and TgAb, it was found that E2was significantly higher in subjects with positive TRAb (TRAb positive, E2=170.3±59.8 pmol/l; TRAb negative, E2=134.0±50.6 pmol/l;P<0.001). No difference in E2was demonstrated according to the results of TPOAb or TgAb. Logistic regression analysis showed that E2was a determinant of positive TRAb, independent of age and BMI. There was no relationship between serum E2and TSH or FT4. However, E2was negatively related to TSH (r=−0.45,P<0.01) in subjects whose TSH levels fell below the reference range (0.3–4.2 mIU/l).ConclusionHigher circulating E2is related to thyroid autoimmunity in males as reflected by positive TRAb.

Abstract. A 36 year old man with a diffuse goitre, signs of mild hypothyroidism, strikingly low levels of T4 (0.9 μg/dl) and T3 (24 ng/dl), elevated TSH (140 μU/ml) and elevated microsomal haemagglutination antibody (MCHA, 1:409 600), subsequently became non-goitrous and euthyroid with a decreased titre of antimicrosomal antibody without any medication. At the time of surgical biopsy, serum levels of T4 and T3 had risen to the normal range (4.6 μg/dl and 73 ng/dl, respectively), serum TSH had decreased to 30 μU/ml and the titre of MCHA to 1:25 600. Thyroid specimens showed Hashimoto's thyroiditis. The activity of thyroid peroxidase (TPO) was normal. The latest examination, 1 year and 3 months after initial evaluation, showed that the patient remained euthyroid with no goitre, that serum thyroid hormones were within the normal range (T4 7.7 μg/dl and T3 97 ng/dl), and that TSH was not detectable. The titre of MCHA decreased strikingly to 1:400.

Inflammation Resolution

Abstract Objective Resolvins are produced by the catabolism of polyunsaturated fatty acids (PUFAs) and play vital roles in inflammation resolution. Resolvins have been associated with autoimmune disorders. This study aimed to measure the level of Resolvin D1 (RVD1) in the serum of Hashimoto's thyroiditis (HT) patients and healthy controls (HCs) and to further analyse its correlation with thyroid autoantibodies and inflammatory factors. Methods Sixty-three participants were recruited, namely, 30 untreated HT patients and 33 sex- and age-matched HCs. Serum RVD1 and inflammatory chemokine (MCP-1 and IP-10) levels were measured by ELISA according to the manufacturer’s protocol. Serum total T3 (TT3), TT4, free T3 (FT3), FT4, thyroglobulin antibody (TgAb), thyroid peroxidase antibody (TPOAb) and thyroid-stimulating hormone (TSH) levels were measured using an electrochemiluminescence immunoassay. Thyroid homeostasis parameters, including the thyroid secretory capacity (SPINA-GT), the total deiodinase activity (SPINA-GD), Jostel’s TSH index (TSHI) and the thyrotroph thyroid hormone sensitivity index (TTSI), were calculated. Results Serum RVD1 levels in HT patients (134.76, 85.35–201.36 pg/mL) were significantly lower than those in HCs (187.64, 131.01–326.85 pg/mL) (P=0.004). As the TPOAb level increased, the RVD1 level showed a decreasing trend (P for trend=0.002). Both multinomial and ordinal logistics analyses revealed that serum RVD1 levels were negatively correlated with TPOAb levels in the adjusted models. Moreover, RVD1 showed a negative correlation with the inflammatory chemokine IP-1 0 (r=–0.276, P=0.034), TSHI (r=–0.269, P=0.036) and TTSI (r=–0.277, P=0.031). Conclusions Thyroid autoimmunity may be associated with low levels of RVD1. Decreased RVD1 levels indicate impaired resolution of inflammation in HT patients.

AbstractWe present a case of a 29-year-old Bulgarian woman with autoimmune thyroiditis and recurrent angioedema. The patient presented with a one-year-long history of recurrent angioedema and Hashimoto’s thyroiditis. Physical examination showed oedema surrounded by erythema on the forearms, and erythematous, itchy plaques spreading over her face, neck, chest, abdomen, and extremities. Blood tests showed elevated total immunoglobulin E (IgE). The patient had been diagnosed with Hashimoto’s thyroiditis and hypothyroidism. She had been taking levothyroxine 50 μg/d, resulting in a good hormonal control; however, her anti-thyroid peroxidase (anti-TPO) antibodies were high. She was started on methylprednisolone and antihistamines. In three weeks, we observed a good therapeutic response to the treatment and the lesions remitted. IgE dropped within normal range. Levels of anti-TPO antibodies were persistently high. In conclusion, patients with angioedema should be tested for thyroid autoimmunity. Further delve into the pathogenesis of angioedema in them is warranted in order to explore the possibility of an underlying atopy in those not responding to the standard treatment with levothyroxine.

Objective: Previous studies have reported an association between iron deficiency (ID) and increased thyroid peroxidase antibody (TPO-Ab) during early pregnancy. The objective of this study was to explore the relationship between ID and thyroid dysfunction, as well as thyroid autoantibodies, during the second trimester of pregnancy. Methods: A total of 1,592 pregnant women (13 to 28 weeks gestation) were enrolled in this cross-sectional study. According to serum ferritin (SF) concentrations, they were divided into ID (SF <20 μg/L) or non-ID (SF ≥20 μg/L) groups. Logistic regression analysis was used to evaluate the association between ID and subclinical hypothyroidism (thyroid-stimulating hormone [TSH] >4.0 mIU/L and free thyroxine [FT4] within the reference range) and thyroid autoimmunity. Results: The prevalence of ID was 23.43% (373/1,592). Compared with the non-ID group, the ID group had lower FT4 levels (13.94 pmol/L [8.91 to 29.82 pmol/L] versus 14.63 pmol/L [8.22 to 47.24 pmol/L]; P<.001]) and higher TSH levels (1.85 mIU/L [0.01 to 7.84 mIU/L] versus 1.69 mIU/L [0.01 to 10.2 mIU/L]; P<.05). Logistic regression analysis confirmed ID as a risk factor for increased thyroglobulin antibody (TG-Ab) (odds ratio 1.974; 95% confidence interval 1.065, 3.657; P<.05), but not for subclinical hypothyroidism or increased TPO-Ab. Conclusion: ID is associated with increased TG-Ab during the second trimester of pregnancy.

ObjectiveIn the recently revised guidelines on the management of thyroid dysfunction during pregnancy, treatment with thyroid hormone (LT4) is not recommended in women without thyroid autoimmunity (TAI) and TSH levels in the range 2.5–4.0 mIU/L, and in a recent study in that particular group of pregnant women, more complications were observed when a treatment with LT4 was given. The objective of the study was therefore to investigate whether variation in thyroid function within the normal (non-pregnant) range in women free of thyroid disease was associated with altered pregnancy outcomes?DesignCross-sectional data analysis of 1321 pregnant women nested within an ongoing prospective collection of pregnant women’s data in a single centre in Brussels, Belgium.MethodsThyroid peroxidase antibodies (TPO-abs), thyroid-stimulating hormone (TSH), free T4 (FT4) and ferritin levels were measured and baseline characteristics were recorded. Women taking LT4, with TAI and thyroid function outside the normal non-pregnant range were excluded. Pregnancy outcomes and baseline characteristics were correlated with all TSH and FT4 levels within the normal range and compared between two groups (TSH cut-off < and ≥2.5 mIU/L).ResultsTobacco use was associated with higher serum TSH levels (OR: 1.38; CI 95%: 1.08–1.74);P = 0.009. FT4 levels were inversely correlated with age and BMI (rho = −0.096 and −0.089;P < 0.001 and 0.001 respectively) and positively correlated with ferritin levels (rho = 0.097;P < 0.001). Postpartum haemorrhage (>500 mL) was inversely associated with serum FT4 levels (OR: 0.35; CI 95%: 0.13–0.96);P = 0.040. Also 10% of women free of thyroid disease had serum TSH levels ≥2.5 mIU/L.ConclusionsVariation in thyroid function during the first trimester within the normal (non-pregnant) range in women free of thyroid disease was not associated with altered pregnancy outcomes. These results add evidence to the recommendation against LT4 treatment in pregnant women with high normal TSH levels and without TPO antibodies.

ObjectiveGraves' disease (GD) is an autoimmune disorder with genetic and environmental background. CTLA-4 is a candidate gene for thyroid autoimmunity. Increased serum levels of soluble CTLA-4 (sCTLA-4) were found in some autoimmune diseases.AimThe aim of the study was to evaluate the relation between sCTLA-4 level and clinical manifestation of Graves' ophthalmopathy (GO), thyroid status, and CTLA-4 gene polymorphisms.DesignSerum sCTLA-4 concentrations were determined in 93 GO patients and 93 healthy controls. In the GO group, CTLA-4 gene was genotyped in five polymorphic sites: g.319C>T, c.49A>G, CT60 by means of PRC-RFLP, Jo31, and g.*642AT(8_33) by means of minisequencing assay.ResultsSerum sCTLA-4 level was significantly higher in the GO group than in controls (median: 7.94 vs 0.00 ng/ml, P=0.000001). This level was higher in severe than in nonsevere GO (median: 10.3 vs 5.6 ng/ml, P=0.01). sCTLA-4 concentration was related neither to the activity of GO nor to thyroid function. Elevated sCTLA-4 levels were observed in carriers Jo31[G] allele (genotype GG+GT) as compared with subjects with an absence of the [G] allele (TT genotype; median: 9.18 vs 4.0 ng/ml, P=0.02). Also patients possessing CT60[G] allele (genotype GG+GA) had higher serum sCTLA-4 levels than subjects who lack the [G] allele (AA genotype; median: 8.73 vs 2.28 ng/ml, P=0.03).ConclusionsIt was shown for the first time that increased serum concentration of sCTLA-4 correlate with the severity of GO. Genetic variation in the CTLA-4 gene region in GD patients at least partially determines the level of sCTLA-4.

Background. Vitiligo is a common skin disorder characterized by macular depigmentation of the skin. The etiopathogenesis of the disease is still unclear, but there is evidence that autoimmunity and endocrine disfunction may be involved.Objective. The aim of this study was to determine whether vitiligo is statistically associated with thyroid autoimmunity.Method. In a prospective case-control study, we compared the frequency of thyroid autoantibodies (thyroglobulin antibody, anti-Tg and thyroid peroxidase antibody, and anti-TPO) in 33 patients with vitiligo and in 33 healthy volunteers. Thyroid autoantibodies and thyroid hormones (thyroxine (T4), triiodothyronine (T3), and thyroid stimulating hormone (TSH) were measured in all subjects.Results. Thyroid functional abnormalities were found in 6 (18.18%) patients. Anti-Tg and anti-TPO were positive in 9 (27.27%) and 8 (24.24%) patients, respectively. In control group, only one subject (3.03%) had abnormalities in thyroid hormonal status, and two subjects had positive thyroid autoantibodies. Compared with the control group, the frequency of both anti-Tg and anti-TPO was significantly higher in those with vitiligo ().Conclusion. This study shows a significant association between vitiligo and thyroid autoimmunity, and that tests to detect thyroid autoantibodies are relevant in patients with vitiligo.

A case of parasitic thyroid nodule is presented. The patient was a non symptomatic 53-year-old white woman, on irregular course of L-thyroxine to treat hypothyroidism due to Hashimoto's thyroiditis. Without a history of thyroid trauma or surgery, she presented a 1.6 x 0.7 x 0.5cm right pre-laryngeal lymph node-like mass which, on ultrasonography, appeared distinct from the gland. TSH, thyroid peroxidase antibody and thyroglobulin antibody serum levels were elevated and T4-free level was normal. Thyroid and total body 99mTc isonitrile scintiscan showed a topic thyroid without radionuclide uptake in the nodule. Fine-needle aspiration of the nodule showed epithelial cells with nuclear atypia and oncocytic changes plus intense lymphoid infiltration and germinative center formation, simulating lymph node metastasis of papillary thyroid carcinoma. Conventional biopsy revealed a parasitic thyroid nodule with Hashimoto's chronic thyroiditis. Parasitic thyroid nodule must always be remembered so that unnecessary surgical assessment and undesirable sequels may be avoided.
