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.

Generalized Seizures

The authors present a case report and review the literature on Hashimoto encephalopathy. The onset of the disease may be marked by focal and then progressively generalized seizures or other neurological symptoms, but a cognitive decline or various psychiatric symptoms may also emerge. High levels of anti-thyroid peroxidase antibodies and/or anti-thyroglobulin antibodies are present in the serum. Corticosteroid treatment usually results in an improvement of symptoms. The syndrome is frequently overlooked and, therefore, the authors strongly recommend testing serum thyroid autoantibodies in cases with encephalopathy of unknown origin independently on the presence of thyroid disease in the patient or family history. The importance of long-term immunosuppressive treatment should also be stressed. Orv. Hetil., 2013, 154, 1312–1316.

Aims: Investigation thyroid dysfunction and autoimmunity in pregnant women with gestational diabetes mellitus. Background: This article was written to evaluate the thyroid function and anti-thyroid peroxidase (anti- TPO) antibodies in pregnant women with gestational diabetes mellitus (GDM). Method: A total of 252 women with GDM and 252 healthy pregnant women were enrolled. Thyroid tests, including TSH, FreeT3, Free T4, and anti-TPO were performed for all women at 24–28 weeks of gestation. Data analysis was then carried out using SPSS ver. 22. Result: There was a significant difference between the experimental group (38.4%) and the control group (14.06%) in terms of the prevalence of subclinical hypothyroidism (p= 0.016). The frequency of anti-TPO was higher in the experimental group than the control group and positive anti-TPO was observed in 18.6% of women with GDM and 10.3% of healthy pregnant women (P= 0.008). Conclusion: Thyroid disorders are observed in pregnant women with GDM more frequently than healthy individuals and it may be thus reasonable to perform thyroid tests routinely.

Background: Dysfunction of the thyroid gland has profound effects on the cardiovascular system. Objective: We aimed to explore the relation of serum thyroid peroxidase antibody (TPO-Ab), as a marker of thyroid autoimmunity with incident hypertension among a euthyroid population. Methods: A total of 3681 participants (1647 men) entered the study. Multivariate Cox proportional hazard models were conducted to estimate the association between TPO-Ab and incident hypertension. Results: The mean age (standard deviation) of the participants was 37.5 (12.8) years. During a median follow-up of 12.2 years, 511 men and 519 women developed hypertension. The multivariable hazard ratios (HRs) and related 95% confidence intervals (CIs) of 1-unit increase in natural logarithm (ln) of TPO-Ab for incident hypertension were 1.09 (1.00-1.19), 1.03 (0.97-1.10), and 1.05 (1.00-1.11) for men, women, and total population, respectively. Moreover, considering the TPO-Ab status as a categorical variable (i.e. TPO-Ab positive or TPO-Ab negative), the multivariate-adjusted HRs (95% CIs) of TPO-Ab positivity for incident hypertension, were 1.33 (0.95-1.85), 1.12 (0.86-1.45) and 1.19 (0.97- 1.46) for men, women, and total population, respectively. Conclusion: Elevated serum TPO-Ab level can contribute to the development of hypertension among euthyroid men during a long follow-up; suggesting a role for thyroid autoimmunity.
