Abstract Background: Papillary thyroid carcinoma (PTC) is more frequently reported in patients with Hashimoto’s thyroiditis (HT), which may be associated with the presence of solid cell nests (SCNs) and focal PTC-like nuclear alterations in the thyroid gland. The point of this consideration was to assess the morphological and immunohistochemical features of SCNs and follicular epithelial changes in Vietnamese patients with HT.Materials and methods: Hematoxylin – Eosin and immunohistochemistry were performed on 20 samples of HT patients who underwent thyroidectomy and were diagnosed with Hashimoto's thyroiditis at Military Medical Hospital 103 from 6/2018 to 6/2019. The expression of five markers (P63, Calcitonin, TTF1, CK19, and HBME-1) to be up-regulated in SCNs and follicular epithelial changes were evaluated.Results: 90% of samples had SCNs with an average of 10 SCNs per section. Only type 1 and type 4 of SCNs were presented (85% and 55%, respectively) and all SCNs were composed of main cells (p63-positive). 15 of 18 cases having SCNs possessed nuclear features of PTC. C-cell hyperplasia was found in one case with 20 clusters. All SCNs showed strong staining with CK19 and weak staining with HBME-1. Follicular epithelial changes were Hürthle cell metaplasia, PTC-like nuclear alterations, atypical solid nodules, papillary and glomerular-like forms (40%, 100%, 25%, and 50%, respectively). Follicular cells of glomerular-like forms (new alteration) especially were positive with CK19 (2 + ~ 3+), HBME-1 (1+), and TTF1, while the components in these follicles were negative with CK19, HBME-1, and TTF1. Among PTC-like nuclear alterations, all of the atypical solid nodules related to HT showed markers related to PTC and without SCNs.Conclusions: Increasing the number of SCNs, as well as PTC-like nuclear alterations of main cells in SCNs and follicular epithelial changes, which were co-expressed CK19 and HBME-1, may suggest precancerous changes in Hashimoto's thyroiditis.

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.
