Abstract Purpose Hashimoto’s thyroiditis is a common disease that also affects pregnant women. We analyzed to what extent the inflammatory process of Hashimoto’s thyroiditis changes with iodine prophylaxis in pregnant women. The target for immunologic activity was levels of thyroid antibodies (TPO). Methods The data were collected retrospectively from 20 consecutive, pregnant patients who had been diagnosed with Hashimoto’s thyroiditis between 01.12.2012 and 01.12.2014 and had received iodine supplementation with 100 µg (n = 1) or 150 µg (n = 19). At least two measurements of TPO antibody levels taken during pregnancy and one after pregnancy were evaluated for each patient in the study group. Results At the end of pregnancy, the average TPO antibody level for the 20 patients studied was 137 IU/ml (+/–214 IU/ml), the lowest being 16 IU/ml and the highest 1000 IU/ml. Despite iodine prophylaxis, levels of TPO antibodies decreased in 18 patients during pregnancy, falling below the reference value of 35 IU/ml in 5 cases. However, in one patient TPO antibodies increased from 60 IU/ml to 237 IU/ml during pregnancy while in another, levels remained constant at 1000 IU/ml. Conclusion Iodine prophylaxis in pregnant women, taken at a dose of 100 or 150 μg daily was shown to have no negative systemic effects on Hashimoto’s thyroiditis in a group of pregnant women with increased TPO levels, and can therefore be recommended for expectant mothers, including those with this disease.

Autoimmune Conditions

Background Autoimmune conditions are associated with adverse pregnancy and offspring outcomes; however, the prevalence in pregnant women is not well understood. Estimates based on administrative data alone may underestimate prevalence. Methods A cross-sectional survey of women attending a tertiary referral hospital for antenatal care in Dec 2018–Feb 2019 and review of the hospital’s maternity database of women giving birth from October 2017–June 2018 to estimate autoimmune disease prevalence. Results A total of 400 women completed surveys (78% response rate) and 41 (10.3%) reported an autoimmune disease, most commonly Hashimoto’s thyroiditis (2.8%) and psoriasis (2.5%). From the maternity database, 112 of 2756 women giving birth (4.1%) had a recorded autoimmune disease, most commonly Hashimoto’s thyroiditis (1.3%) followed by coeliac disease, Graves’ disease, and immune thrombocytopenic purpura (all 0.4%). Conclusion Autoimmune disease prevalence in pregnant women is higher when self-reported and may be more common than previously reported using administrative data.

Abstract.The relationship between Hashimoto’s thyroiditis and vitamin D has been demonstrated in several studies. The aim of the present study was to evaluate vitamin D concentrations in patients with Hashimoto’s thyroiditis, the effect of vitamin D therapy on the course of disease, and to determine changes in thyroid autoantibody status and cardiovascular risk after vitamin D therapy. We included 75 patients with Hashimoto’s thyroiditis and 43 healthy individuals. Vitamin D deficiency is defined as a 25-hydroxy vitamin D (25(OH)D3) concentration less than 20ng/mL. Vitamin D deficient patients were given 50.000 units of 25(OH)D3 weekly for eight weeks in accordance with the Endocrine Society guidelines. All evaluations were repeated after 2 months of treatment. Patients with Hashimoto’s thyroiditis had significantly lower vitamin D concentrations compared with the controls (9.37±0.69 ng/mL vs 11.95±1.01 ng/mL, p < 0.05, respectively). Thyroid autoantibodies were significantly decreased by vitamin D replacement treatment in patients with euthyroid Hashimoto’s thyroiditis. Also, HDL cholesterol concentrations improved in the euthyroid Hashimoto group after treatment. The mean free thyroxine (fT4) concentrations were 0.89±0.02 ng/dL in patients with Hashimoto’s thyroiditis and 1.07±0.03 ng/dL in the healthy control group (p < 0.001). The mean thyroid volumes were 7.71±0.44 mL in patients with Hashimoto’s thyroiditis and 5.46±0.63 mL in the healthy control group (p < 0.01). Vitamin D deficiency is frequent in Hashimoto’s thyroiditis and treatment of patients with this condition with Vitamin D may slow down the course of development of hypothyroidism and also decrease cardiovascular risks in these patients. Vitamin D measurement and replacement may be critical in these patients.

Summary Aim of this study is to evaluate new and controversially discussed indications for determining the thyroglobulin (Tg) level in different thyroid diseases to support routine diagnostics. Methods: The following groups were included: 250 healthy subjects without goiter, 50 persons with diffuse goiter, 161 patients with multinodular goiter devoid of functional disorder (108 of them underwent surgery, in 17 cases carcinomas were detected), 60 hyperthyroid patients with autonomously functioning nodular goiter, 150 patients with Hashimoto’s thyroiditis and 30 hyperthyroid patients with Graves’ disease. Results: The upper limit of the normal range of the Tg level was calculated as 30 ng Tg/ml. The evaluation of the collective with diffuse goiter showed that the figure of the Tg level can be expected in a similar magnitude as the thyroid volume in milliliters. Nodular tissue led to far higher Tg values then presumed when considering the respective thyroid volume, with a rather high variance. A formula for a rough prediction of the Tg levels in nodular goiters is described. In ten out of 17 cases with thyroid carcinoma, the Tg was lower than estimated with thyroid and nodular volumes, but two patients showed a Tg exceeding 1000 ng/ml. The collective with functional autonomy had a significantly higher average Tg level than a matched euthyroid group being under suppressive levothyroxine substitution. However, due to the high variance of the Tg values, the autonomy could not consistently be predicted with the Tg level in individual cases. The patients with Hashimoto’s thyroiditis showed slightly decreased Tg levels. In Graves’ disease, a significantly higher average Tg level was observed compared with a matched group with diffuse goiter, but 47% of all Tg values were still in the normal range (< 30 ng/ml). Conclusion: Elevated Tg levels indicate a high probability of thyroid diseases, such as malignancy, autonomy or Graves’ disease. However, as low Tg concentrations cannot exclude the respective disorder, a routine Tg determination seems not to be justified in benign thyroid diseases.

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.
