Introduction: Beta-thalassaemia is caused by point mutations leading to decreased production of beta-globin, which results in defective red blood cells and ineffective erythropoiesis. Complications are microcytic hypochromic anaemia, extramedullary haematopoiesis and increased intestinal iron absorption due to compensation mechanisms. The resulting iron overload can be aggravated by recurrent blood transfusions necessary for treatment of anaemia and may cause several endocrine...

Background: Final height (FH) is reduced in congenital adrenal hyperplasia (CAH), due both to overtreatment by hydrocortisone therapy and to advanced epiphyseal closure linked to hyperandrogenism by Hydrocortisone therapeutic insufficiency.Objective and hypotheses: To evaluate the efficacy and safety of the addition of an androgen receptor competitor and an aromatase inhibitor to reduced hydrocortisone doses.Method...

Background: On reviewing practical aspects of intravenous bisphosphonate use in our tertiary Children’s Hospital, we noted disparity between departments who prescribed these drugs. This included issues pertinent to patient safety and hospital management, e.g. the need for overnight admission for the first infusion, blood tests and monitoring for adverse events (AEs). We therefore decided to survey the practices of other tertiary Paediatric Endocrinology Centres.<p cla...

Background: Bartter syndrome represents a rare severe condition, autosomal recessive, corresponding to several genes, characterized by an illness of the renal ascending branch of the handle of Henle. Only 15 cases of BSHPT have been communicated, either in publications or orally, but none presented such severe bone manifestation as ours.Objective and hypotheses: To present bone features of two patients suffering from severe BHSPT, so as the therapeutic a...

Background: Leprechaunism, due to a mutation of both alleles of insulin receptor gene, is a most severe and precociously life-threatening condition, difficult to treat.Objective and hypotheses: In leprechaunism rhIGF1 may replace insulin through I the insulin-like metabolic properties of its own receptor.Method: rh IGF1 was continuously subcutaneously administered through a.pump from the age of four months and adjusted according to...

Background: The optimal method to assess GH status remains controversial. GH provocation tests are used and the Insulin Tolerance Test (ITT) is regarded as the ‘gold standard’ to diagnose GH deficiency (GHD). The original selection of 0, 20, 30, 60, 90 and 120 min time points is still used in many protocols worldwide, but variations have evolved.Objective and hypotheses: Comparing standard ITT (StdITT) to a revised (RevITT) protocol.<p clas...

Background: Continuous glucose monitoring (CGM) measures interstitial glucose and displays trend arrows, showing the direction and rate of change in glucose. Trend arrows allow the child/youth to take action to prevent hyper- and hypoglycaemia. Effective strategies for adjusting insulin for trend arrows are lacking. The JDRF CGM Study Group recommended a 10–20% increase/decrease in the insulin dose. However, the bolus dose is dependent on amount of food to be consumed and...

Background: Child growth is a dynamic process and influenced by various environmental factors. When measured at short intervals, growth of healthy children shows certain characteristic patterns, which have rarely been studied, but are of great importance for clinical purposes. The study was approved by the Ethical Committee of the University of Potsdam.Aim: To see whether measurements of height using photographic display...

Background: Body composition measures differ between DEXA scanners. If an old DEXA is replaced a transition period for double measurements on the old and the new scanner is needed.Objective and hypotheses: To evaluate differences between the old (Hologic QDR 2000) and new (Hologic Discovery Wi) scanner and to calculate formula transforming measurements.Method: 51 double measurements were performed on a group of 41 children and adul...

Objective: To provide etiology-based diagnostics to pediatric patients with diabetes in Belgium using routine clinical phenotyping and thorough genotyping.Methods: A Belgian GENEPEDIAB study consortium was created to screen, using routine diagnostic tools, for monogenic forms of diabetes in pediatric patients followed in convention centers for type 1 or type 2 diabetes, while presenting atypical biological and clinical f...
