Introduction: The Immune Thrombocytopenic Purpura (ITP) and Graves Disease (GD) have in common an autoinmune physiopathology. ITP is characterized by a platelet count less than 100 × 106/l in the absence of other cause. On one hand, ITP has been associated with thyroid dysfunction, without developing GD. On the other hand, GD might develop with moderate thrombocytopenia, generally more than 100×109/l. It is described that in most cases ITP might...

Background: In 2011, ATA and AACE published Guidelines on pediatric Graves’ disease (GD) treatment. Nevertheless it is still a controversy.Objective and hypotheses: SPEDP conducted the first nationwide questionnaire survey among all the Endocrinologists and Pediatricians in the Portuguese Public Health System Hospitals about pediatric GD treatment in order to know the reality in our country.Method: SPEDP designed and distribut...

Background: Graves’ disease (GD) is the most common cause of hyperthyroidism in the pediatric population. T helper 17 (Th17) IL-17A+CD3+CD4+ cells represent a novel subset of T helper cells that play an active role in inflammatory and autoimmune diseases. Although methimazole (MMI) lowers the levels of thyroid autoantibodies, little is still known about its influence on cell-mediated immune response. The role of Th17 cells in GD pathogenesis remains uncertain and the impa...

Suitably treatment of Basedow–Graves’ disease (BGD) provide the minimization of time to develop the medicamental remission. Research: determine clinical, laboratory particularities, evaluate efficiency of pharmaceutical treatment of BGD in children in different age groups. Materials and methods: 35 children with BGD were examined (4 boys, 31 girls): 1st group (Tanner 1) n=4, 7.5±0.65 years; 2nd – (Tanner 2–4) n=22, 12.32±0.31 yea...

Background: Neonatal Graves’ disease (NGD) occurs in 1–2% pregnancies with maternal Graves’ disease. Thyroid auto-antibodies can persist in the maternal circulation even 10 years after thyroidectomy and can lead to NGD in the absence of maternal thyrotoxicosis. Both maternal stimulating autoantibodies and maternal thyroxine can cross the placenta, and have been implicated in neonatal craniosynostosis.Objective and hypotheses: We report a c...

Clinical case: A 17-year-old patient was observed with a diagnosis of GD in October 2016. When the patient was examined in the hormonal profile there were hyperthyroidism, a high titer of antibodies to the TSH receptor, in connection of which thyrostatic therapy initiated. In dynamics since November 2018 there has been a pronounced increase in the total volume of the thyroid gland. Firstly she was examined at the Endocrinology Research Center in October 2019...

Background: Neonates born from mothers with Graves’ disease are at risk to develop hyperthyroidism due to placental transmission of TSH-receptor antibodies. Neonatal hyperthyroidism should be effectively diagnosed and treated to prevent severe complications of this disease (cardiac symptoms, poor weight gain, severe neurological manifestations).Objectives: To describe the post-natal follow-up of neonates born from women with Graves’ disease.</p...

Background: The standard pharmacological treatment strategy of thyroid storm according to 2016 Japan Society of Pediatric Endocrinology Guideline. Although thiamazole (MMI) is recommended be used as the first choice in Graves’ disease, the effect of propylthiouracil (PTU) to block the conversion from T4 to T3 in peripheral tissues encourages clinicians to use against thyroid storm in its very early phase, and switch to MMI later. Nevertheless, the optimal timing of the sw...

Background: Graves’ disease (GD) is almost always the cause of hyperthyroidism in children. Studies carried out for recent years confirm an important role of T regulatory cells (Tregs) in the development of autoimmune diseases. However, the interactions between T-cell response and Treg proliferation in GD is still poorly understood.Objective and hypotheses: The aim of this research was the assessment of the in vitro proliferation of Treg ce...

Introduction: Recent studies have revealed the presence of zinc and the expression of zinc transporter (ZnT) family members in most endocrine cell types. Moreover it was demonstrated that the ZnT family plays an important role in the synthesis and secretion of many hormones like insulin. We studied the prevalence of ZnT8 Ab in patients with autoimmune thyroid diseases (AITD).Material and methods: The study was performed in the group consisting of 20 Grav...
