HbA1c and Glucose Management Indicator relationship: can HbA1c determination be avoided?

Navarro Moreno Constanza , Sanchez Ruiz Daniel , Jose Garcia Garcia Emilio , Elizagarate Izaskun Marchueta , Gomez Gila Ana Lucia ,

Introduction: Continuous Glucose Monitoring (CGM) devices have introduced new metrics to assess metabolic situation of patients with type 1 diabetes mellitus (T1DM). Among them, the glucose management indicator (GMI) provides a proxy to HbA1c, however, these measures do not always match.Purposes: To evaluate the concordance between GMI and HbA1c, and determinate in which scenarios GMI could replace HbA1c.Subjects a...

All Roads Don’t Lead to Rome After All!!

Diab Dina , El Sayed Shaymaa

Abstract: Hypoglycemia is a frequent and one of the major metabolic emergencies in any age, causing a significant dilemma to reach the correct diagnosis and perform the appropriate management. it Has potentially devastating consequences on brain development and cognitive functions. It Is a heterogeneous disorder with many different possible etiologies, including hyper-insulinism, glycogen storage diseases, fatty acid oxidation defects, hormonal deficiencies (g...

Albert , Dattani Mehul T. ,

Three patients from two unrelated families in Malta; one consanguineous (siblings: Patient 1, male and Patient 2, female) and one non-consanguineous (Patient 3, male), manifested hypogonadotropic hypogonadism with delayed puberty, intellectual disability, scoliosis, and ataxia with cerebellar hypoplasia on MRI. GnRH tests revealed low peak LH and FSH concentrations in the patients: Patient 1; LH 2.3 IU/L, FSH 4.4 IU/L (14.3y), Patient 2; LH 3.6 IU/L, FSH 6.4 IU/L (12.5y), Pati...

Multiple Malformations Extending the Phenotypic Spectrum of Antley–Bixler Syndrome in a Patient with P450 Oxidoreductase Deficiency due to Two Novel Mutations of the POR Gene

Janchevska Aleksandra , Idkowiak Jan , Caredda Elisabeta , Hurst Jane , Dattani Mehul T , Arlt Wiebke , Spoudeas Helen A

Background: P450 oxidoreductase deficiency (PORD) is characterised by glucocorticoid and sex steroid deficiency and skeletal malformations, resembling Antley–Bixler syndrome (ABS, MIM 124015), a skeletal malformaton phenotype also present in patients with fibroblast growth factor receptor 2 mutations (FGFR2, MIM 176943). While genetic testing confirms both conditions, establishing the exact diagnosis on clinical grounds can be challenging.Objective ...

Alterations in resting-state functional connectivity in patients with congenital adrenal hyperplasia

Messina Valeria , van´t Westeinde Annelies , Padilla Nelly , Lajic Svetlana ,

Background: Patients with congenital adrenal hyperplasia (CAH) are treated with life-long glucocorticoid (GC) replacement therapy. Negative effects on cognition, brain structure and function during working memory tasks have been identified. To date, no studies on functional connectivity during rest have been performed in patients with CAH. One study conducted on patients with Cushing’s syndrome, another disorder of cortisol imbalance, suggests that long-t...

Very High Dehydroepiandrosterone Sulfate (DHEAS) in Serum of an Overweight Female Adolescent without a Tumor

Iliev Daniel , Braun Regina , Sanchez-Guijo Alberto , Wudy Stefan , Heckmann Doreen , Bruchelt Gernot , Rosner Anika , Grosser Gary , Geyer Joachim , Binder Gerhard

Here, we report on a female adolescent with overweight and a very high DHEAS serum level. The hypothesis that the origin of DHEAS excess was the presence of either an ovarian or a suprarenal DHEAS-producing tumor was not confirmed. Sonographic and MRT investigations did not support its presence. In addition, effective dexamethasone suppression of DHEA and DHEAS excluded this diagnosis. Steroid sulfatase (STS) hydrolyses alkyl and aryl steroid sulfates to their unconjugated for...

The Diverse Phenotype of Mutations in T3 Receptor Alpha (TRα)

van Gucht Anja , Demir Korcan , Zwaveling Nitash , Wennink Hanneke , Buyukinan Muammer , Catli Gonul , Dundar Bumin Nuri , Meima Marcel , Visser Edward , van Trotsenburg Paul , Visser Theo , Peeters Robin

Background: Recently, the first patients with resistance to thyroid hormone (RTHα) due to inactivating mutations in TRα1 have been identified. These patients are characterized by growth retardation, delayed bone development, mild cognitive defects, delayed motor development and abnormal thyroid function tests.Objective and hypotheses: We hypothesized that the phenotype of a TRα mutation depends on its location, e.g. if it is present only i...

Atypical Features in Patients with Leprechaunism Suggesting a Wide Clinical Spectrum of Disease

Katugampola Harshini , Improda Nicola , Shah Pratik , Gordon Hannah , Amin Rakesh , Peters Catherine J , Semple Robert K , Dattani Mehul T

Background: Donohue syndrome (DS) is the most severe form of insulin-resistance due to autosomal recessive mutations in the insulin receptor gene. Typical features include pre-/postnatal growth impairment, hyperinsulinaemic hyperglycaemia with fasting hypoglycaemia, nephrocalcinosis, recurrent sepsis, little adipose tissue, soft tissue overgrowth, hirsutism, acanthosis nigricans and facial dysmorphism. However, additional comorbidities may be present, affecting prognosis.<...

Inhibition of Teneurin-2 (TENM2) Leads to Upregulation of UCP1 in Human White Adipocytes

Tews Daniel , Fischer-Posovszky Pamela , Wabitsch Martin

Background: Heat generation in UCP-1 active cells as present in brown adipose tissue contributes to the regulation of energy homeostasis. Brown adipose tissue is known to be present in neonates and infants and has recently also been demonstrated in children and adults. Interestingly, a transition of white adipocytes into a brown phenotype has been documented in vitro in mouse and human cells, yet the underlying mechanisms are still not resolved. Using transcriptome an...
