Introduction: Non-Hodgkin lymphoma (NHL) involving the hypothalamus and pituitary gland is rare. Central nervous system involvement by NHL may be either as a primary tumour or from systemic lymphoma. We report an interesting case of aggressive central nervous system (CNS) lymphoma presenting as pituitary macroadenoma.Case report: A 67-year-old Caucasian woman presented with sudden onset of left eye ptosis and diplopia. Examination showed left third nerve...

Introduction: Obstructive Sleep Apnoea (OSA) is more common in women with Polycystic Ovary Syndrome (PCOS). There is paucity of data regarding the impact of OSA in women with PCOS.Methods: We conducted a retrospective study using electronic patients’ records of premenopausal women with PCOS who were first seen in the weight management clinic (WMC) between March/2008 and November/2014. PCOS diagnosis was documented either by referring clinician or es...

Background: Human cohorts and animal models provide compelling evidence suggesting the role of vitamin B12 in modulating the risk of diabetes and adiposity via developmental programming. We recently demonstrated that neonates born to mothers with low B12 levels in pregnancy have adverse cord blood lipid profile and in vitro studies in human adipocytes with low B12 showed increased cholesterol biosynthesis. Therefore, we hypothesized that vitamin B12 deficiency may pla...

Renalase is a recently discovered flavin adenine dinucleotide (FAD)-dependent oxidase, predominantly secreted into the circulation from the kidney and regulates catecholamine degradation and metabolism. Renalase gene is also present in heart muscle, skeletal muscle and liver cells in humans, and in mouse testicles. Four isoforms of renalase gene has been identified in humans (hRenalase1 to hRenalase4), however only hRenalase1 is detected in human blood suggesting that hRenalas...

Introduction: Therapeutic durability of GLP1-based therapies in patients with type 2 diabetes mellitus (T2D) is incompletely understood. Our aim was to explore the therapeutic effects of GLP1 based therapies in patients with T2D.Methods: This was a retrospective study on patients with T2D (n=55) who attend a specialist clinic at UHCW, Coventry, and who had been treated with the GLP1 based therapy, Liraglutide, for at least 6 months. A successful...

Introduction: Glucocroticoids (GCs) which are routinely used in the treatment of Acute Lymphocytic Leukemia (ALL), found recently to be beneficial in a subset of AML patients resistant to chemotherapy, by promoting leukemia cells apoptosis. Current studies indicate that vitamin D (VitD) deficiency is highly prevalent among AML patients, posing vitamin D as a therapeutic supplementation. Our previous study demonstrated that VitD exerts inhibitory effect on Dexamethasone-induced...

Introduction: Endocrinopathy is frequently seen in systemic amyloidosis and commonly involves thyroid and gonads. We report a case of primary adrenal failure secondary to systemic light chain amyloidosis (AL), involving kidney, liver, spleen, gut, nerves and tongue.Case: A 42-year-old Somalian lady presented with 2-year history of lethargy, febrile episodes and 21 kg weight loss. Investigations showed increase in serum lambda light chain 103 mg/l (5.7&#1...

Introduction: Polycystic Ovary Syndrome (PCOS) is associated with insulin resistance, visceral obesity -metabolic syndrome (MS) and non-alcoholic fatty liver disease (NAFLD). Fetuin-A, human protein: α2-Heremans-Schmid glycoprotein is an abundant serum protein exclusively expressed in the liver and has been suggested to act as a link between obesity, insulin resistance (IR), and MS.Aims: A) To determine levels of Fetuin-A in PCOS women. B) To invest...

Aims: Treatment regimes for low testosterone are well established but reasons for treatment change and patient preferences are less well known. We looked at the type of testosterone replacement, subsequent modification of replacement and reason for that change.Methods: Data were collected from the electronic case notes of 50 patients on testosterone replacement for at least 6 months attending endocrine clinics in a University Teaching Hospital.<p cla...

Background: Gestational diabetes (GDM) is characterized by insulin resistance and a pro-inflammatory state, both factors possible related to adipokine expression. In our study we have endeavoured to assess serum levels of insulin-sensitising omentin and pro-inflammatory thrombospondin-1 (TSP-1) in GDM.Subjects and methods: The study included 20 women with GDM, diagnosed according to the WHO criteria, age 29.7±5.5 (mean±S.D.), BMI...
