Introduction: PIMS-TS [Paediatric Inflammatory Multisystem Syndrome Temporally associated with SARS-CoV-2] is a unique clinical complication of COVID -19 infection in paediatric patients. We report a case of a child presenting with PIMS-TS and new onset type 2 diabetes.Presentation: A previously healthy 15 year old boy of Bengali-Indian origin presented to the hospital with polyuria, polydipsia, dry cough, abdominal pain and 1 episode of...

Background: Daily recombinant human growth hormone (rhGH) has been utilized since 1985 and has been proven to increase height velocity and improve body composition in growth hormone deficiency, various genetic syndromes and chronic kidney disease. Safety and efficacy are well established. Long-acting growth hormone (LAGH) analogs have been developed to improve compliance and patient experience. There are several LAGH preparations in development or early commer...

Background: Central hypothyroidism is rare in children. It is often part of multiple pituitary hormone deficiency but can occur in isolation. Isolated central hypothyroidism may be due to mutations in TSHB, TRHR or IGSF1, involved in TRH signalling. We present an adolescent with a novel truncating variant of IGSF1, resulting in delayed puberty, central hypothyroidism and macroorchidism.Case presentation: A 15-year-old ma...

Background: Mild isolated neonatal hyperthyrotropinaemia (HTT), defined as elevated thyroid stimulating hormone (TSH) with normal free thyroxine (FT4) concentrations, may be identified by newborn screening programmes for congenital hypothyroidism (CHT) or when neonatal thyroid function tests (TFTs) are performed for a clinical indication. Reported HTT incidence rates vary (from 0.001-0.1%)1. Case definition also varies, with some authors using a TSH...

Gestational Diabetes (GDM) increases risk of developing type 2 diabetes in the mother and child later in life however, despite the increasing prevalence of GDM, its molecular mechanism remains unknown. A recent Genome-Wide Association Study (GWAS) identified a unique genetic association of the novel 5th hexokinase, hexokinase domain component-1 (HKDC1) to gestational glucose tolerance at 28 weeks of gestation linking it to GDM. We have previously shown that liver-specific over...

Background: Congenital hypogonadotropic hypogonadism (CHH) is caused by impaired function of GnRH neurons, which clinically manifests by incomplete or absent puberty and infertility. The phenotype may be broader with other developmental anomalies such as anosmia, which is known as Kallmann syndrome. To date, there are more than 40 genes in which mutations underlie CHH. Cornelia de Lange Syndrome (CdLS) is characterized by facial dysmorphia, psychomotor delay, ...

Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing were shown to carry a mutation in the X-linked StAR-related lipid transfer...

We report a term male with diazoxide-unresponsive congenital hyperinsulinism (CHI) (spontaneous conception, non-consanguineous, no family history). The patient did not have macroglossia, exomphalos or lateralised overgrowth (cardinal Beckwith-Wiedemann spectrum (BWSp) features) (1). There was no polyhydramnios, macrosomia, facial naevus simplex, ear creases/pits, diastasis recti or nephromegaly/hepatomegaly (suggestive BWSp features) (1).A targeted massi...

Background and objective: Given phenotype variability as well as limited utility of conventional endocrine investigations in reaching the diagnosis in a 46,XY patient suspected of a disorder of sex development (DSD), there is an increasingly stronger argument for considering targeted genetic sequencing at an earlier stage of the evaluation process. This study focused on identifying the relationship between clinical examination, endocrine and radiological assessment, as well as...

Background: We recently demonstrated that both ritonavir-boosted lopinavir (LPV/r) and lamivudine (3TC, a nucleoside analogue) given to breastfed infants can reduce the risk of post natal HIV transmission (ANRS 12174 trial; Nagot, Lancet 2016). In another setting we previously showed the occurrence of adrenal dysfunction in newborn perinatally exposed to LPV/r leading to acute adrenal insufficiency in premature babies (Simon, JAMA 2011).Objective and hyp...
