Introduction: Treatment with recombinant human growth hormone (rhGH) is useful for growth failure in short stature children. But there are some reports of renal disease or complication occurring during rhGH treatment. GH and insulin-like growth factor-1 (IGF-1), together with other growth factors and cytokines, have important roles in adaptive morphological and functional changes in the kidney. This study was aimed to reveal the renal complication of hematuria...

Background: Recombinant human growth hormone (rhGH) is usually administered via subcutaneous injections. Besides well-known adverse events such as peripheral edema, benign intracranial hypertension, and slipped capital femoral epiphysis, a less known and rare side effect is local lipoatrophy, a phenomenon with an incompletely understood pathophysiology. Here, we report a case of Prader Willi Syndrome (PWS) who presented with local lipoatrophy following hGH.</p...

This study aims to investigate the efficacy and safety of recombinant human GH (rhGH) in the treatment of idiopathic short stature (ISS).Methods: The data of 200 ISS children, who were treated with rhGH from January 2008 to December 2016, were collected and retrospectively analyzed. The data of height, bone age, blood glucose, insulin, thyroid function and IGF-1 were collected, and annual growth rate (AGR), height standard deviation score (HtSDS) and rel...

Background: Small for gestational age (SGA) children who experience rapid and exaggerated postnatal catch-up are prone to develop insulin resistance and to progress faster into puberty, resulting in a shorter final height. Short, non-catch-up SGA children treated with recombinant human GH (rhGH) may present with the same sequence. In a previous controlled study from our group performed in short SGA children, metformin – added to rhGH therapy – improved endocrine-meta...

Background: Coeliac disease (CD) can be associated with impaired growth in children after a prolonged period of Gluten-free diet (GFD). A small percentage of CD patients does not show catch-up growth during GFD because of GH secretion deficiency (GHD) that could be associated with antipituitary autoantibodies (APA).Objective and hypotheses: This study aims to evaluate the efficacy of recombinant human GH (rhGH) therapy on final adult height in children w...

Introduction: In 2009/2010 Hospital Virgen del Rocío, Seville, Spain changed the treatment of patients with GH deficiency (GHD) from various original recombinant human GH (rhGH) to a biosimilar rhGh (Omnitrope®, Sandoz).Objective: To evaluate the consequences on growth parameters of switching treatment, from original rhGHs to Omnitrope® in children with GHD, in a window period of 36 months.Metho...

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...

Gonadotropin-releasing hormone (GnRH) is the master hormone regulating the reproductive axis and its pulsatile secretion is crucial for puberty onset and fertility. Disruption in GnRH neuron development or hypothalamic function can lead to absent or delayed puberty (DP) due to GnRH deficiency, with a phenotypic spectrum from severe delayed puberty to partial or complete Hypogonadotropic Hypogonadism (HH). HH can also be present as a shared trait with other neurodevelopmental d...

Background: Studies in animal models revealed that brown and white adipocytes derive from different progenitor cells. Molecular characteristics of these cells have not been investigated in detail in humans.Objective and hypotheses: To identify novel markers of human brown adipocyte progenitor cells.Method: Progenitor cells from human paired deep neck and subcutaneous adipose tissue samples were obtained from n=12 subjects ...

Background: Steroids are found in human blood predominantly as sulfated steroids. Conjugation of steroids increases their solubility in blood, facilitating their physiological regulation and excretion. Chromatographic separation and quantification of an extensive number of sulfated steroids is challenging. For instance, androgen sulfates are structurally related and their signals are very similar in mass spectrometry.Objective and hypotheses: Some of the...
