Background and objective: Children with chronic kidney disease (CKD) have impaired growth that leads to short stature in adulthood and treatment with recombinant human growth hormone (rhGH) is associated with improved growth. This study aimed to evaluate the efficacy and safety of daily rhGH (Jintropin®) in children in China with growth failure caused by CKD prior to transplantation.Methods: Prepubertal patients (2–13 years old) with CKD-relate...

Background: 46, XX testicular disorder of sex development (DSD) and 11β-hydroxylase deficiency (11β-OHD) are two extremely rare types of disorder of sex development. No coexistence has been reported yet.Case Description: Here we reported the first patient diagnosed as the coexistence of 11β-OHD and 46, XX testicular DSD basing on clinical, biochemical, molecular, cytogenetic, and functional experiment findings. A 22-year-old male showed sm...

Background: Thyroid damage is known to occur during experimental iodine-induced goiter. MicroRNAs (miRNAs) are a class of small non-coding RNAs regulating gene expression. Dysregulation of specific miRNAs can interfere with tissue homeostasis. The purpose of this study was to investigate the dynamic expression profiles of miRNAs during adequate or mild-excess iodine supplementation in the iodine-deficient thyroid.Methods: Hyperplastic goiter was induced ...

Objectives: Lonapegsomatropin (SKYTROFA; TransCon hGH), a prodrug of somatropin, is approved by the EMA and FDA for once-weekly treatment of pediatric growth hormone deficiency (GHD). Lonapegsomatropin uses TransCon® technology, which combines a parent drug transiently linked to an inert carrier to achieve sustained release. The characterization of anti-drug antibodies (ADAs) was assessed in 3 phase 3 trials of lonapegsomatropin in pediatric GHD.Met...

Pituitary adenomas constitute the third most common intracranial neoplasm. Adenoma cells either express no hormone (null cell adenoma) or hormones of different cell lineage. About 1% of pituitary adenomas shows a plurihormonal expression pattern, which may either be attributed to one cell lineage or rarely to different cell lineages. In addition, the development of separate pituitary adenomas may be observed in 0.5–1.5% of surgical specimens and in up to 10% of autopsy ca...

Background: Adult GHD results from insufficient growth hormone (GH) secretion from the anterior pituitary gland and may represent either a continuation of childhood-onset GHD or GHD acquired during adulthood. Clinically, adult GHD is associated with central adiposity, decreased lean muscle mass, increased fat mass, decreased bone mineral density, and reduced quality of life. Current standard of care consists of GH replacement via daily injections. Lonapegsomatropin (SKYTROFA; ...

The Endocrine Society recommends urinary or plasma metanephrines as first choice screening tests for phaeochromocytoma due to their high sensitivity. Test specificity is limited by the influence of many commonly prescribed medications resulting in false positive results and additional investigations. The aims of this retrospective study were to (1) Determine the diagnostic accuracy of urinary metanephrines using current cut-off values and (2) Evaluat...

Introduction: 3-Iodothyronamine (T1AM) is a novel thyroid hormone derivative, which has been detected in rat blood and tissues. In vivo, T1AM has been reported to produce several functional effects, including the switch of fuel utilization from carbohydrates to lipids. In the present work we used rat white adipocytes to investigate T1AM uptake, metabolism, and metabolic effects.Methods: Rat white adipocytes were incubated with exogenous T1AM. The ...

Maternal hypothyroidism disrupts fetal brain development in the rat; affected parameters include several neuron-specific cytoskeletal proteins and neurotransmitter metabolic enzymes. The aim of this study was to determine whether maternal hyperthyroidism also impacts upon fetal neuronal development.Partially thyroidectomised rat dams were subcutaneously implanted with osmotic pumps to infuse either 1.5 micrograms thyroxine/100 g body weight/day (HYPER) o...
