A 62-year-old Asian British female presented with increasing tiredness. She had multiple co-morbidities and was prescribed steroid inhalers for suspected asthma. Her type 2 diabetes mellitus, previously well controlled on metformin, had worsened over a short period of time (48 to 85 mmol/mol). On examination, she was obese (weight 82 kg, BMI 43 kg/m2), hypertensive (155/78 mmHg); rest of the examination was unremarkable. The blood test revealed undetectable cortisol...

A 61 year-old woman presented with a two year history of facial hirsutism and frontal balding. She did not report voice change or acne. Menarche was at age 14 with regular menses until a hysterectomy (with ovarian preservation) for menorrhagia aged 29. She had a past medical history of T2DM and gastric bypass surgery. She was not on androgenic medication. Examination revealed clinical hyperandrogenism with androgenic alopecia and hirsutism (FG score 20) but no cliteromegaly. T...

Introduction: A 22q11.2 deletion syndrome (velocardiofacial syndrome) is an autosomal dominant disorder affects various organs including the parathyroid gland. Because of its incomplete penetrance, multi-system affectation, and variable clinical presentation, the diagnosis is often delayed or never made. Delayed diagnosis may have significant impact on morbidity and mortality. We present a patient with a long history of clinical features of a syndrome which was diagnosed after...

Introduction: Diaphoresis, or excessive sweating, is well recognised as a presenting complaint for endocrine disorders such as hyperthyroidism, acromegaly, and phaeochromocytoma. However, diaphoresis is an unusual presenting complaint for Cushing’s syndrome.Case: We present the case of a 35-year-old lady who first presented to health services for symptoms of excessive sweating, and feeling hot most of the time. Whilst initial investigations such as ...

Introduction: Graves’ disease is an autoimmune disorder which may lead to thyroid overactivity and eye disease. Oestrogen and progesterone are thought to be immunomodulatory and have been postulated to play an important role in the difference in prevalence of autoimmune disorders between men and women. Autoimmune disorders, including autoimmune thyroid disease, are often quiescent during pregnancy with an increased prevalence postpartum. The increase in immune mediated th...

Nutrient sensors mediating the stimulatory effects of food-derived carbohydrates and lipids on incretin and insulin secretion have been widely studied. However, mechanisms underlying amino acid regulation of those processes remain poorly understood. GPR142 was recently reported to be highly expressed in pancreatic beta cells and selectively activated by L-Tryptophan (L-Trp). Moreover, synthetic GPR142 agonists were demonstrated to stimulate glucose-dependent insulin secretion ...

The aim of our studies was to examine the effect of some food, drink and medical plants and their molecules on female ovarian endocrine and other functions in vitro and in vivo. We analysed the effects of plant (green tea, rooibos, ginkgo, flaxseed, chia, yukka) extracts and plant substances (green tea polyphenols, green tea epigallocatechin-3-gallate, curcumin, resveratrol, diadzein and diosgenin) on the release of hormones and markers of proliferation, apop...

Background: In acromegaly, carbohydrate metabolism disorders (CMD) are frequently observed. The effect of therapy of acromegaly on pathogenesis of CMD is not clear.Aim: To assess the effect of somatostatin analogues (SSA) on pathogenesis of carbohydrate metabolism disturbance in acromegaly.Patients and methods: 103 acromegaly patients were examined (31 men, 72 women; age 54 (46–61) years; 60 had newly diagnosed acromegaly (NA)...

The increasing prevalence of obesity is paralleled by related metabolic disorders such as insulin resistance and type 2 diabetes mellitus (T2DM). Extensive efforts across disciplines are made to reveal underlying mechanisms and develop effective therapies against obesity and its comorbidities. Since PET–CT studies provided evidence for functional brown adipose tissue (BAT) in adult humans, this specialized thermogenic compartment of adipocytes is in the focus of current r...

Objective: To evaluate the frequency of symptoms of Cushing’s disease (CD) at baseline and it dependence on different quantities.Material and methods: Clinical and laboratory data of 44 patients with CD (40 females and four males, 37.9±10.5 years old), duration of the disease 35.5 (22; 75) months.Results: Complaints: i) >80% – fatigability, weight gain, apathy, and headache, ii) 40–50% – loss of libido,...
