Autoimmune thyroid diseases are characterized by lymphocytic infiltration of the thyroid gland. Chemokines are crucial in the recruitment of lymphocytes and might play an important role in the pathogenesis of autoimmune thyroid disease. The aim of this study was to test the feasibility of analysing by one-tube reverse-transcriptase polymerase chain reaction (RT-PCR) technique CC chemokine profiles in samples obtained by fine needle aspiration biopsy (FNAB). In 27 out of 35 (77%) samples, the material was sufficient for analysis and in 16 (59%) chemokines were detected, thus demonstrating the potential of this technique. Moreover, even in this small group, a statistically significant increase of CCL3 and CCL4 was found in samples from patients with autoimmune thyroid disease as compared to those with multinodular goiter. Chemokine profile measured by improved multiamplification techniques in FNAB thyroid samples may become a useful complementary tool for the management of thyroid autoimmune disease as it constitutes a source of data for research of their pathogenesis.

Autoimmune polyglandular syndrome type 3 (APS-3) is an uncommon condition marked by autoimmune thyroid disease (ATD) linked with other autoimmune issues, excluding Addison's disease. We report a case of a 41-year-old man who was hospitalized due to exhaustion and macrocytic anemia, later diagnosed with APS-3, which included Hashimoto's thyroiditis, pernicious anemia resulting from autoimmune gastritis, and pre-existing vitiligo. Diagnostic results indicated positive intrinsic factor antibodies, a gastric biopsy compatible with gastritis, elevated thyroid peroxidase antibodies, and significant findings from a thyroid ultrasound.

Background And Objectives: Antibody-negative autoimmune encephalitis (AE) is a form of encephalitis characterized by the absence of detectable autoimmune antibodies, despite immunological evidence. However, data on management of patients with antibody-negative AE in the intensive care unit (ICU) are limited. This study aimed to explore the characteristics and subtypes of antibody-negative AE, assess the effects of immunotherapy, and identify factors independently associated with poor functional outcomes in patients requiring intensive care.

The increase of the incidence of autoimmune diseases and, at the same time, a significant surge in the number of regenerative/anti-aging medicine treatments carried out, raises the need to systematise the current knowledge on the safety of the use of hyaluronic acid fillers in patients with autoimmune diseases and to frame management guidelines for aesthetic doctors. One of the most prevalent autoimmune diseases is chronic lymphocytic thyroiditis, so-called Hashimoto's disease, which affects one in every 5-10 women who visit a regenerative medicine doctor. Women in the perimenopausal and menopausal period, aged 40-54 years, were the single largest target group for aesthetic treatments.

Background: Among environmental factors, infectious agents, including , can act as triggers for autoimmune thyroid diseases. Therefore, this study aimed to investigate the correlation between autoimmune Hashimoto's thyroiditis with infection.
Methods: The participants in this case-control study were 74 individuals 17-62 years who were divided into two groups, including 38 diagnosed Hashimoto's thyroiditis patients from an outpatient clinic of endocrinology and 36 apparently healthy individuals that were selected from family members of cases group age-matched and sex-matched.
