Clinical and Biochemical Characteristics of Severe Hypothyroidism Due to Autoimmune Thyroiditis in Children

Conclusion: In children with severe hypothyroidism, the most sensitive symptoms are growth arrest and weight gain despite the fact that, in some children, the auxological parameters at presentation could be within normal values for the population. The specific biochemical profile closely correlates to the severity of thyroid hormone deficiency and involves mostly erythropoiesis, liver function, and kidney function. Pituitary enlargement should be considered in each child with severe hypothyroidism. It is necessary to conduct prospective studies evaluating the actual frequency of anti-TSHR antibodies and pituitary enlargement in children with extremely high TSH, especially those presenting without goiters.

CONCLUSION: In the present study, two OBI female patients with type 1 AIH were positive for anti-HBc but negative for HBsAg and HBV DNA. With regard to the consequences of OBI, prior to prophylactic treatment, it is recommended to screen HBV markers including anti-HBc in all diagnosed patients with AIH..

In conclusion, children and adolescents with ITP present high frequency of latent and overt polyautoimmunity even for autoantibodies other than ANA. Therefore, ANA and other non–organ-specific and organ-specific autoantibodies should be considered for assessment during ITP patients’ follow-up.

Abstract Reversible lysine acetylation of histones is a key epigenetic regulatory process controlling gene expression. Reversible histone acetylation is mediated by two opposing enzyme families: histone acetyltransferases (HATs) and histone deacetylases (HDACs). Moreover, many non-histone targets of HATs and HDACs are known, suggesting a crucial role for lysine acetylation as a posttranslational modification on the cellular proteome and protein function far beyond chromatin-mediated gene regulation. The HDAC family consists of 18 members and pan-HDAC inhibitors (HDACi) are clinically used for the treatment of cert...

AbstractAtezolizumab (Tecentriq®), a fully humanized, monoclonal anti-programmed cell death ligand-1 (PD-L1) antibody, is the first immune checkpoint inhibitor to be approved, in combination with carboplatin and etoposide, for the treatment of adult patients with extensive-stage small cell lung cancer (ES-SCLC). Approval was based on primary data from the multinational phase I/III IMpower133 trial in PD-L1-unselected patients with previously untreated ES-SCLC. In this trial, induction therapy with atezolizumab plus carboplatin and etoposide followed by maintenance therapy with atezolizumab alone significantly prolonged...

Helminth parasites are effective in biasing Th2 immunity and inducing regulatory pathways that minimize excessive inflammation within their hosts, thus allowing chronic infection to occur whilst also suppressing bystander atopic or autoimmune diseases. Multiple sclerosis (MS) is a severe autoimmune disease characterized by inflammatory lesions within the central nervous system; there are very limited therapeutic options for the progressive forms of the disease and none are curative. Here, we used the experimental autoimmune encephalomyelitis (EAE) model to examine if the intestinal helminth Heligmosomoides polygyrus and it...

In this study, we demonstrated that p53 was downregulated in CD4+ T cells from patients with aGVHD compared with the non-aGVHD group. Furthermore, we confirmed that low expression of CCCTC-binding factor (CTCF) in CD4+ T cells from aGVHD cases is an important factor affecting histone H3K9/K14 hypoacetylation in the p53 promoter and p53 downregulation. Restoring CTCF expression in CD4+ T cells from aGVHD patients increased p53 amounts and corrected the imbalance of Th17 cells/Tregs. Taken together, these results provide novel insights into p53 downregulation in CD4+ T cells from aGVHD patients.

Latitudinal gradient effect is described for several autoimmune diseases including celiac disease in the United States. However, the association between latitude and global celiac disease prevalence is unknown. We aimed to explore the association between latitude and serology-based celiac disease prevalence through meta-analysis.

Your thyroid, a tiny, butterfly-shaped gland located in front of your windpipe (trachea) and below your voice box (larynx) can have a profound impact on your health and well-being. Throughout life, your thyroid is constantly producing hormones that influence your metabolism. These hormones affect your mood, energy, body temperature, weight, heart, and more. A brief overview of hypothyroidism Your thyroid produces two kinds of thyroid hormones: T4, or thyroxine, and T3, or triiodothyronine. These hormones influence every cell, tissue, and organ in your body, from your muscles, bones, and skin to your digestive tract, brain,...

Nivolumab, a fully human IgG4 immune checkpoint inhibitor (ICI) antibody, has been approved for a variety of cancers. Several endocrine-associated immune-related adverse events have been reported, but the incidence rate is relatively low. This is a case of a patient with gastric cancer who underwent nivolumab therapy, leading to type 1 diabetes as well as adrenocorticotropic hormone (ACTH) deficiency and hypothyroidism almost simultaneously. A 70-year-old man with no previous history of diabetes was treated with nivolumab monotherapy for gastric cancer in November 2018. After 8 courses of nivolumab, he was diagnosed with t...

Myasthenia Gravis (MG), an autoimmune neurological disease, is more frequently found amongst adults than amongst children. Our research provides data on the clinical symptoms, forms of MG, effective treatment, the presence of thymoma and the effect of thymectomy in children with MG in Israel. The database of a tertiary pediatric medical center was retrospectively reviewed for patients under 18 years of age diagnosed between the years 2000-2020 with either ocular or systemic acquired myasthenia gravis.
