Adult Growth Hormone Deficiency (AGHD) is associated with osteoporosis. PTH is secreted in a circadian rhythm and temporal fluctuations in PTH concentration, particularly at night, appear to be important in the regulation of bone turnover. Serum phosphate is an important determinant of PTH, with changes in phosphate preceding fluctuations in PTH concentration. We examined the difference in PTH and phosphate circadian rhythmicity in AGHD patients with normal and reduced bone mi...

Adult Growth Hormone Deficiency (AGHD) is associated with reduced bone mineral density (BMD) and bone turnover. Abnormalities in PTH circadian rhythmicity, including blunted nocturnal rise in PTH concentration have been reported in AGHD and may underlie the pathogenesis of osteoporosis. Serum phosphate is an important regulator of PTH, with changes in phosphate concentration preceding fluctuations in PTH. We examined the effect of oral phosphate therapy on PTH circadian rhythm...

Background: Subclinical hypothyroidism (SCH) is a common condition affecting 7.5–8.5% of women and 2.8–4.4% of men. Overt hypothyroidism is characterized by dyslipidemia, however the controversy persists regarding the lipids level in subclinical hypothyroidism (SCH) and its clinical significance. Recent evidence also shows that T4 replacement therapy may improve lipid profile.Aim: The aim of this study is to assess the prevalence of dyslipidemi...

BackgroundMedical nutrition therapy is often the initial step in the management of Prediabetes and diabetes mellitus. Postprandial glycaemia contributes significantly to the glycaemic control of patients with diabetes mellitus. The beneficial effects of soluble dietary fibre in reducing postprandial glycaemia have been established. The 2017 global burden of disease (GBD) report shows that 97.000 deaths result from low fibre intake. Despite the this, the ...

Case history: A 34-year old Caucasian nurse presented to her GP with a 7 month history of abdominal pain. She was found to have PTH-dependent hypercalcaemia with Stage 3A chronic kidney disease (corrected calcium 3.43 mmol/l, phosphate 0.62 mmol/l, total vitamin D 32 nmol/l, PTH 214.9 pmol/l, creatinine 117 μmol/l and eGFR 45 ml/min/1.73m2). On direct questioning, she reported fatigue, generalised weakness and intermittent joint pains affecting her lower back and bo...

Background: At the Metabolic Bone Centre in Sheffield, UK, patients with asymptomatic primary hyperparathyroidism (PHPT) are followed up annually through a register, with annual blood tests, questionnaires inquiring about symptoms or renal stones within the past year, and biennial DXA scans, which doctors then evaluate. Patients are recalled to the clinic if their reported symptoms and/or biochemical results suggest abnormalities associated with PHPT requiring...

Objective: Patients with Sheehan syndrome (SS) are predisposed to coronary artery disease (CAD) due to risk factors like abdominal obesity, dyslipidemia and chronic inflammation. In addition to estimate CAD risk enhancers like high sensitive C reactive protein (hsCRP), apolipoprotein B (ApoB) and lipoprotein A [Lp(a)], this study applies Framingham risk score (FRS) and coronary artery calcium (CAC) score to compute a 10-year probability of cardiovascular (CV) events in SS...

Introduction: Immobilization hypercalcemia is uncommon condition associated with limited movements following brain and spinal cord lesions. Immobilization results in stimulation of osteoclastic bone resorption hypercalciuria and hypercalcemia.Case report: 57 year female, Background of Breast Cancer (Treated with Skin sparing mastectomy and adjuvant radiotherapy) admitted following large subdural hematoma leading to craniotomy and evacuation of hematoma. ...

Introduction: Paraneoplastic endocrine syndrome such as hypercalcemia in malignancy is well-known. However, paraneoplastic insulin resistance is rarely described and its management is challenging.Case history: A 33 years old teetotal gentleman with BMI of 37.5 kg/m2 and histological diagnosis of desmoid tumour presented with osmotic symptoms, weight loss, hyperglycemia and normal ketones. He was hemodynamically stable with no clinical or bioch...

Glucocorticoids (GC) are commonly prescribed and their use is associated with adverse metabolic side effects. 5a-reductase (5aR) inhibitors are also frequently prescribed mainly for their ability to inhibit the conversion of testosterone to dihydrotestosterone. However, they also have a role to inactivate and clear GCs. We hypothesised that 5aR inhibitors have the potential to exacerbate the adverse metabolic effects of GCs. We conducted a prospective, randomised, study in 19 ...
