Direct and indirect effects of androgens on the musculoskeletal system

Claessens Frank , Michael Laurent , Dubois Vanessa , Khalil Rougin , Jardi Ferran , Vanderschueren Dirk

Global knockout models of the androgen receptor (ARKO) illustrates the many roles androgens and their receptor have in the development of male reproductive organs and the gender differences in many features like the musculoskeletal system. However, neither the global ARKO nor orchidectomy models discriminate between direct and indirect effects of androgens. To determine direct and indirect effects of androgens on muscle, we developed a muscle-specific ARKO (called satARKO for ...

Patients with self-limited delayed puberty harbour mutations in multiple genes controlling GnRH neuronal development

Howard Sasha , Andre Valentina , Guasti Leo , Cabrera Claudia , Barnes Michael , Cariboni Anna , Dunkel Leo

Objectives: Abnormal pubertal timing affects >4% of adolescents and is associated with adverse health outcomes. Up to 80% of variation in the timing of pubertal onset is genetically determined. Self-limited delayed puberty (DP) segregates in an autosomal dominant pattern, but in the majority the neuroendocrine pathophysiology and genetic regulation remain unclear. Mis-regulation of the embryonic migration of GnRH neurons has been implicated in the pathogenesis of DP (Howar...

Bisphosphonate therapy in Williams-Beuren syndrome: case series

Maduemem Kene , Kennedy Elaine , Morrissey Rose , Riordan Michael , O'Riordan Stephen M P

Introduction: Hypercalcaemia in Williams-Beuren syndrome (WBS) is usually mild and transient, but may be severe in about 5% of new presentations. Often some children will not respond well to traditional therapies.Case report: We describe three cases of acute hypercalcaemia and their management in a regional Paediatric unit. Case 1: A 16-month-old known WBS girl, presented with irritability, reduced feeding. Corrected serum calcium was 4.51 mmol/l. She wa...

AZP-3813, a bicyclic 16-amino acid peptide antagonist of the human growth hormone receptor as a potential new treatment for acromegaly

Milano Stephane , Kurasaki Haruaki , Tomiyama Tatsuya , Reid Patrick , Jan Van der Lely Aart , Culler Michael D.

Medical treatment of acromegaly is based on either suppressing pituitary GH secretion or inhibiting GH action by preventing interaction with its receptor in order to suppress the elevated levels of IGF1. AZP-3813 is a 16-amino acid, bicyclic peptide antagonist of the GH receptor (GHR) derived from peptide sequences discovered using a unique, cell-free in vitro transcription-translation system screened against the human GHR, and that was optimized by rational design to increase...

Global impact of PCOS awareness month: challenges and opportunities

Malhotra Kashish , Synn Cuen Pan Carina , Davitadze Meri , Manolopoulos Konstantinos , O'Reilly Michael , Arlt Wiebke , Kempegowda Punith

Background: September is celebrated as PCOS awareness month worldwide and is aimed at improving the lives of those with PCOS, promoting research, and strengthening advocacy efforts. While significant financial and human resources are invested in promotions during this month, to the best of our knowledge, there is no evidence to show the impact of this initiative. In our study, we evaluated the global digital impact of PCOS Awareness Month, tracking commonly used hashtags as su...

Adverse events associated with supraphysiological glucocorticoid dosing in congenital adrenal hyperplasia (CAH): results of a structured literature review

Sharma Vijay , Coope Helen , Maskin Kamran , Parviainen Lotta , Porter John , Withe Michael , Barnes Anne-Marie

Objectives: Congenital adrenal hyperplasia (CAH) is a rare condition caused by enzyme deficiency in cortisol biosynthesis. Patients with CAH require lifelong therapy, with the aim of replacing deficient hormones (cortisol +/− aldosterone) and reducing excess androgen production. Guidelines state that the lowest effective glucocorticoid (GC dose) should be used; however, current GC therapy is suboptimal, and supraphysiological GC doses are used to reduce excess androgens....

Canagliflozin and liraglutide effect on myocardial damage in diabetic rats with experimental myocardial infarction

Timkina Natalya , Simanenkova Anna , Shimshilashvili Anzhelika , Timofeeva Valeria , Chernikova Alena , Minasian Sarkis , Galagudza Michael

Background: Cardiovascular events are the major cause of mortality among patients with type 2 diabetes mellitus (DM2). Menopause in women additionally increases cardiovascular risk. Despite myocardial infarction (MI) treatment approach in diabetic patients is not specific, some glucose-lowering drugs could have cardioprotective properties. In general, most glucagon-like peptide-1 receptor agonists (GLP-1Ra) and sodium-glucose co-transporter-2 inhibitors (SGLT-2i) have cardiova...

Clinical features and survival outcomes of patients with ectopic Cushing’s syndrome: a single-center study

Golounina Olga , Rozhinskaya Liudmila , Arapova Svetlana , Pikunov Michael , Khandaeva Patimat , Fadeyev Valentin , Marova Evgenia , Belaya Zhanna

Objective: To analyze long-term treatment outcomes and to determine prognostic factors affecting the survival of patients with ECS. Matherials and methods: Retrospective, observational study on 147 patients (88 women, 59 men) with ECS diagnosed between 1990 and 2021. Various imaging studies were performed on all patients to find the source of ACTH producing neuroendocrine tumor (NET). Multivariable analysis was performed using a Cox proportional hazards ...

Male pituitary-gonadal axis function in obstructive sleep apnoea syndrome: the effect of continuous positive airway pressure

Leigh Richard , Hamon Siobha n , McWeeney Michael , O'Loughlin Aonghus , O'Shea Paula

Background: Obstructive sleep apnoea syndrome (OSAS) is common; disproportionately affecting the overweight and obese. Continuous positive airway pressure (CPAP) is the first-line treatment for moderate to severe OSAS. Clinical equipoise exists as to whether CPAP treatment directly affects pituitary-gonadal hormone synthesis.Study Aim: This study aimed to determine the effect of CPAP treatment on gonadotropins, prolactin, sex-hormone binding-globulin (SH...

Soluble alpha klotho in blood is a new and highly stable biomarker

Ribeiro de Oliveira Longo Schweizer Junia , Haenelt Michael , Schilbach Katharina , Stormann Sylvere , Schopohl Jochen , Bidlingmaier Martin

Background: Soluble alpha klotho (sαKL) is a circulating protein that has been linked to the growth hormone (GH) axis. We previously showed its association to disease activity in patients with acromegaly, with considerable robustness towards biological confounders. However, there is scarce data in literature regarding the analytical performance of the assay, and pre-analytical stability of sαKL in blood samples. Objective: We aimed to evaluate ...
