Introduction: Monogenic Type 1 diabetes (T1D) is a rare disease caused by pathogenic variant in a single gene leading to dysregulation of immune system. T1D is combined with other autoimmunity like immune cytopenias, inflammatory bowel disease, rheumatoid arthritis, atopic eczema, autoimmune thyroid disease etc in these patients. Pathogenic variants in the AIRE, FOXP3, LRBA, IL2RA, CTLA4, STAT3 and STAT1 genes have...

Background: In XLH, high circulating FGF23 causes hypophosphatemia, rickets, and short stature.Objective and hypotheses: To evaluate KRN23 effects on serum phosphate (Pi) level and rickets severity in XLH children in a Phase 2 study.Method: 52 XLH children (ages 5–12 years, ≤Tanner 2) received KRN23 subcutaneously biweekly (Q2W) or monthly (Q4W). Serum Pi was measured at 2-week intervals. KRN23 dose was titrated (maximum...

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disease among women of reproductive age with a prevalence of about 8% according to the Androgen Excess Society (AES) criteria. The pathophysiology of PCOS is not well understood and it is associated with a high prevalence of metabolic disorders. During puberty, irregular menses and acne are common, thus making the diagnosis of PCOS in adolescence challenging.Objective and hypothe...

Background: The hepatokine FGF21 signals through a dual receptor complex consisting of FGFR1c and the obligatory co-receptor β-Klotho to regulate glucose and lipid metabolism. Interestingly, female mice with Fgf21 transgenic overexpression are not only resistant to high-fat diet induced obesity but also present with hypogonadotropic hypogonadism (HH) and infertility. Loss-of-function (LOF) mutations in FGFR1 are a frequent cause of congenital HH (CHH). W...

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...

Background: Patients with autosomal dominant hypocalcemia type 1 (ADH1), due to germline gain-of-function calcium-sensing receptor (CASR) mutations, have hypocalcemia and seizures, hyperphosphatemia, hypercalciuria and inappropriately low parathyroid hormone (PTH) concentrations. Treatment for ADH1 comprises calcium and vitamin D analogs, however, their use predisposes to nephrocalcinosis and renal impairment. In contrast, recombinant human PTH(1-34) may incre...

Objective: Remission rates in young people with Graves’ hyperthyroidism are 25% or less after a 2-yr course of thionamide antithyroid drug (ATD). Immunomodulatory agents could potentially improve outcome by facilitating immune tolerance. We wanted to explore whether rituximab, a B lymphocyte depleting agent, would increase remission rates when administered with a short course of ATD.Design: This was an investigator-...

Lonapegsomatropin (TransCon hGH) is an investigational once-weekly prodrug of somatropin for the treatment of GHD. Previous trials in treatment-naïve (52-week heiGHt Trial) and treatment-experienced children (26-week fliGHt Trial) have reported the efficacy and safety of lonapegsomatropin. Subjects were eligible to enter the open-label extension enliGHten Trial, which continues to evaluate weekly lonapegsomatropin in pediatric GHD. In heiGHt, treatment-naïve subjects...

It is estimated that 1-5% of children and adolescents in Europe suffer from severe obesity (corresponding to an adult BMI > 40 kg/m2). However, in risk stratification, the occurrence of metabolic complications is more important than BMI itself. The study aimed to assess the occurrence of cardiovascular risk factors in a cohort of children and adolescents with severe obesity.Patients and Methods: The analysis included 140 patients (75 ...
