Introduction: Adrenocortical tumors are very rare in children, with a prevalence of just 0.3 cases/million/year. Autonomic hormone production by adrenal cortical tumors may cause peripheral precocious puberty.Case report: A 4-year-old boy was presented by his parents because of pubertal behavior with aggressive features and a significant increase in the size of the penis. The parents also noticed a strong growth spurt and sweat odor. The boy had a good g...

South Asian (SA), British-born adults have increased cardiovascular (CV) risk factors compared to White Europeans (WE). Early detection of CV risk may allow intervention. The Manchester HAPO (Hyperglycaemia and Adverse Pregnancy Outcomes) cohort showed babies of SA origin were born significantly shorter, lighter and had a lower mean BMI SDS than those of WE origin. We now report ethnic differences in body composition and CV markers in childhood. Measurements on 102 children (5...

Background: The fundamental challenge of developing a long-acting growth hormone (LAGH) is to create a more convenient growth hormone (GH) dosing profile while retaining the excellent safety, efficacy, and tolerability of daily GH. With GH receptors on virtually all cells, replacement therapy should achieve the same tissue distribution and effects of daily (and endogenous) GH while maintaining levels of GH and resulting IGF1 within the physiologic range....

Background: TransCon GH is a novel sustained-release recombinant human GH (somatropin) prodrug in development for children with GH deficiency (GHD). It is designed to release unmodified GH and intended to provide comparable efficacy, safety, tolerability, and immunogenicity to daily GH with once-weekly dosing. Based on results from a phase 2 trial, which demonstrated comparable efficacy (annualized height velocity for TransCon 0.21 mg GH/kg per week of 12.9 cm/year vs 11.6 cm/...

Background: TransCon Growth Hormone is a once-weekly sustained-release prodrug of recombinant human growth hormone (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified hGH is released with a Cmax and AUC comparable to daily therapy. TransCon hGH leverages the known pharmacology of daily hGH and is being developed for the treatment of growth hormone deficiency (GHD).Objective and hypotheses: Both hGH levels and resulting IGF-I leve...

Background: Diabetes is a recognised long term sequelae in childhood cancer survivors following bone marrow transplantation and total body irradiation (BMT/TBI), due to a combination of insulin deficiency and resistance.Aim: To characterise presentation, treatment and clinical course of diabetes in childhood leukaemia survivors post BMT/TBI.Method: A single centre retrospective case note review of diabetes post BMT/TBI identified f...

Background: The liver is one of the most important organs in glucose metabolism and closely related to diabetes pathophysiology. Non-alcoholic fatty liver disease (NAFLD) is well known in type 2 diabetes mellitus (DM), but also adult patients with type 1 DM are at increased risk for NAFLD.Objective and hypotheses: Here, we studied the prevalence of liver disease in a representative number of children and adolescents with type 1 DM in Germany.<p class...

Background: TransCon GH is designed as a once-weekly sustained-release prodrug of recombinant human GH (hGH, somatropin). Based on the inert TransCon prodrug technology unmodified native hGH is released with a Cmax and AUC comparable to daily therapy. TransCon GH leverages the known pharmacology of daily hGH and is being developed for the treatment of GH deficiency (GHD) in children and adults.Objective and hypotheses: Develop a safe and efficacious sust...

Background: Children with GHD, in addition to short stature, may experience physiological symptoms as well as social and emotional problems. Assessing these impacts is critical for understanding the extent of GHD burden and assessing treatment benefit. Since many children initiating treatment are too young to self-report information, we must rely on adult reporters. However, according to FDA guidelines and established measure development principles, adult reporter information ...

Objective and hypotheses: The objective was to use whole-genome RNA profiling of testicular biopsies by DNA strand-specific RNA-sequencing to explore the causative role of isolated congenital cryptorchidism in azoospermia and/or infertility.Method: Fifteen cryptorchid patients, aged 7 months to 5 years, were enrolled in this study and underwent orchidopexy. During surgery, testicular tissue biopsies were collected and split in half for histological exami...
