Introduction: Human ovary is commonly the target of an autoimmune attack in cases of organ- or non-organ-specific autoimmune disorders. Hashimoto’s thyroiditis (HT) is likely to be associated with ovarian dysfunction and diminished ovarian reserve. The classical hormonal test assessing ovarian reserve as early follicular phase serum levels of FSH, inhibin B and estradiol (E2), which are interdependent, and the calculation of the number of antral follicles by transvaginal ...

Background/Aim: Diabetes with extra-pancreatic features in children can have a monogenic aetiology. Single gene testing is undertaken when children present with the characteristic clinical features suggestive of the underlying aetiology. We aim to assess the utility of comprehensive genetic testing for all monogenic diabetes genes in children with diabetes and any non-autoimmune extra-pancreatic features from a population with a high rate of consanguinity.<p class="abstext...

An oral GH secretagogue (GHS), LUM-201, stimulates GHSR-1a receptor to enhance endogenous GH pulsatile release. In moderate iPGHD, pulses of GH are found but at reduced levels, resulting in decreased IGF-1 and poor growth. The impact of LUM-201 on GH profiles during treatment of such children has not been reported.Objective: To characterize GH profiles, defined by deconvolution analysis, based on GH concentration in a time series and its...

NMDA (N-Methyl-D-aspartic acid) receptors have been shown to control the timing of sexual maturation in laboratory animals. Therefore, variants in genes impacting NMDA receptor signaling might be predicted to affect human puberty. We studied an extended family with extremely delayed puberty (menarche at 16.5 - 18 years for female family members and pubertal onset at 16 years for male family members). Exome sequencing revealed a rare missense variant (F900V) in DLG2, w...

6q24 methylation defects are the most common cause of Transient Neonatal Diabetes Mellitus (TNDM). The clinical picture is one of impaired insulin secretion, small for gestational age and diabetes mellitus aged <6 months. This case illustrates the fluctuation between both hyper- and hypoglycaemia that can been seen in 6q24 methylation defects. A term, small for gestational age baby boy was noted to have hypoglycaemia (BSL 1.8 mmol/l) at 1.5 h of life which resolved with or...

Introduction: Hashimoto's thyroiditis (HT) and Graves' disease (GD) become increasingly common in children's population. Pathogenesis of autoimmune thyroid diseases (AITD) bases on coexistence of genetic predisposition and environmental triggers which finally drive to breakdown of immune tolerance. Many mechanisms in human body moderate process of inflammation. While some of them answer for up-regulation, some agents like B regulatory lymphocytes (...

Background: Approximately one baby in 2000-3000 is born with congenital hypothyroidism (CHT). Newborn screening of CHT is conducted in different countries by the measurement of either thyroid stimulating hormone (TSH) of free thyroxine (FT4) or both. Whereas most Western countries screened CHT by using a blood spot collected on day 3 to 5 of life, some countries' programmes measure umbilical cord blood TSH or FT4 for the screening of CHT. In our maternity ...

Background: Anti-Müllerian hormone (AMH) inhibits the in utero growth of the Müllerian structures in female fetuses. In neonates with suspected disorders of sexual development (DSDs), the presence of testicular tissues and functioning Sertoli cells can be investigated by testing for serum AMH concentration.Objective: To evaluate the performance of two new AMH assays in a hospital laboratory.Method: The technical performan...

Introduction: Beta thalassemia major (BTM), a hereditary haemoglobinopathy due to a deficiency in the synthesis of beta-globin, leads in the homozygous state to severe anemia requiring regular transfusions associated with chelator treatment. The endocrine complications encountered in BTM, secondary to martial overload by direct damage to the glandular parenchyma, continue to be observed in our consultations, although early and well-managed chelation can reduce...

Background: Treatment of precocious puberty with GnRH analogues is well established. But there are concerns about weight gain in patients on this treatment. There have been conflicting reports about the effect of GnRH analogues on weight.Objective and hypotheses: To assess the change in BMI in children treated with GnRH analogues within a UK Endocrine Service and to analyse the patient/parent experience of the treatment.Method: A r...
