2nd Year Pharmacokinetic and Pharmacodynamic Modeling of Long-Acting Human Growth Hormone (MOD 4023) in Growth Hormone Deficient Children

Fisher Dennis M. , Jaron Mendelson Michal , Vander Shelly , Koren Ronit , Hart Gili

Background: OPKO Biologics is developing MOD-4023, a long-acting growth hormone (GH), intended for weekly dosing for the treatment of idiopathic GH deficiency in children. At ESPE2015, we presented pharmacokinetic (PK) and pharmacodynamic (PD, based on IGF-1) models for weekly MOD-4023 administration in children aged 3–11 years. Those models were based on data collected during the ‘PKPD period’ (the second steady state dose of MOD-4023) and monthly values during...

The Development of Gonadoblastoma in a 3-Year-Old Girl with 46,Xdel(Y)p11.3, Gonadal Dysgenesis and Associated Congenital Anomalies

Kolesinska Zofia , Rojek Aleksandra , Kedzia Helena , Blaszczynski Michal , Latos-Bielenska Anna , Kapczuk Karina , Niedziela Marek

Background: One of the crucial aspects of the management of disorders of sex development is the assessment of the risk of malignant transformation of a dysgenetic gonad.Objective and hypotheses: The PCR analysis of germ-cell risk factors as the presence of the TSPY gene may be helpful in decision making of an early gonadectomy.Results: We report a 46,Xdel(Y)p11.3 girl with gonadal dysgenesis, that was referred to the Depar...

Pharmacokinetic and Pharmacodynamics Modelling of MOD-4023 (a Long-Acting Human GH) in GH-Deficient Children

Fisher Dennis , Jaron-Mendelson Michal , Amitzi Leanne , Koren Ronit , Hart Gili

Background, objective, and hypotheses: OPKO Biologics has produced a long-acting human GH (hGH), MOD-4023, containing copies of a naturally-occurring C-terminal peptide (CTP) to markedly increase GH’s in vivo residence. We describe the construction and validation of a pharmacokinetic (PK)/pharmacodynamics (PD) model to characterise the relationship between MOD-4023 dose, MOD-4023 serum concentrations (Cserum), and IGF1 responses in healthy adults, GH-deficient (G...

Thyroid Function and Autoimmunity in Children with Newly Diagnosed Type 1 Diabetes Mellitus

Niechcial Elzbieta , Skowronska Bogda , Gertig-Kolasa Anna , Krzysko Izabela , Stankiewicz Witold , Michalak Michal , Fichna Piotr

Background: Patients with type 1 diabetes (T1DM) are at a high risk of having other autoimmunological diseases. The most common coexisting disease is autoimmune thyroiditis, which is diagnosed in 15–30% diabetic patients. The incidence of the disease depends on the age, sex, and duration of T1DM.Aims and objectives: This study aims to assess the prevalence of anti-thyroid peroxidase antibodies and anti-thyroglobulin antibodies in children with newly...

Comparison of Two Family-Intervention (Parents Only vs Parent and Child) in the Treatment of Childhood Obesity

Meyerovitch Joseph , Yackobovitch-Gavan Michal , Wolf Dafna , Phillip Moshe , Shalitin Shlomit

Background: Obesity in adolescence is associated with a 70% likelihood of obesity or overweight in adulthood. Hence, effective intervention programs for childhood obesity in high-risk populations are needed.Objectives: i) To compare the efficacy of two intervention strategies, involving parents only vs parent and child, to a control group, in the treatment of childhood obesity. ii) To identify clinical demographical and biochemical predictors for decreas...

Nutritional Supplementation, Sleep Patterns and Growth in Short and Lean Prepubertal Children

Machtei Ayelet , Lebenthal Yael , Lazar Liora , Shamir Raanan , Phillip Moshe , Yackobovitch-Gavan Michal

Background: GH secretion is affected by duration and quality of sleep. Studies examining the connection between sleep and linear growth have reported conflicting results. Recently, we reported that nutritional supplementation was effective in promoting growth in children. In the present study, we extended our evaluation of the nutritional supplement to assess the association between nutrition, sleep and growth.Objective and hypotheses: To examine whether...

Fasting and Post-Meal Levels of Appetite Regulating Hormones, before and Following GH Treatment, in Children with Idiopathic Short Stature

Yackobovitch-Gavan Michal , Gat-Yablonski Galia , Shtaif Biana , Phillip Moshe , Lazar Liora

Background: Poor appetite is common in children with idiopathic short stature (ISS), and is usually improved with GH therapy.Objective and hypotheses: To investigate the effect of GH therapy on appetite regulating hormones following a standard meal test (SMT) and to examine the association between these changes and growth response, body composition and resting energy expenditure (REE).Method: Nine ISS pre-pubertal children underwen...

The Role of Early Thyroid Imaging in Children with Congenital Hypothyroidism

Oron Tal , Lebenthal Yael , Ben-Yishai Shimon , Tenenbaum Ariel , Yackobovitch-Gavan Michal , Phillip Moshe , Lazar Liora

Background: Congenital hypothyroidism (CH) occurs in 1:3000–1:4000 newborns. The majority of newborns with CH are detected by routine screening programs and treatment is promptly initiated following confirmatory thyroid function testing. Although early imaging studies do not influence the treatment decision or management, they establish the underlying diagnosis and may distinguish between permanent and transient CH.Objective: To assess the role of e...

Diagnosing growth hormone deficiency - Can a combined arginine and clonidine stimulation test replace two separate tests?

Oron Tal , Krieger Avihu , Yakobovich-Gavan Michal , Tenenbaum Ariel , Diamant Rotem , Phillip Moshe , Lazar Liora ,

Objective: Given a large number of false-positive growth hormone deficiency (GHD) diagnoses from a single GH stimulation test in normal children, two different pharmacological tests, performed on separate days or sequentially, are required. This study aims to assess the reliability and safety of a combined clonidine-arginine stimulation test (CACST).Design: Retrospective, single-center, observational study....
