Evaluating the role of testosterone in cerebrospinal fluid secretion

Westgate Connar , Botfield Hannah , O'Reilly Michael , Hodson David , Sinclair Alexandra

Idiopathic intracranial hypertension (IIH) is a condition characterised by raised intracranial pressure (ICP) that primarily affects obese women of reproductive age. The aetiology is poorly understood but involves imbalance of cerebrospinal fluid (CSF) secretion and absorption. IIH patients share similar phenotypic characteristics to PCOS patients, a condition with a distinct androgen signature. We hypothesise that obesity and androgen excess maybe...

GLP-1 reduces cerebrospinal fluid secretion and intracranial pressure: a novel treatment for idiopathic intracranial hypertension?

Botfield Hannah , Uldall Maria , Mitchell James , Gonzalez Ana Maria , Jensen Rigmor , Sinclair Alexandra

Background: Idiopathic intracranial hypertension (IIH) predominantly affects obese women of childbearing age. IIH is characterised by increased intracranial pressure (ICP) which results in visual loss and disabling headaches. ICP dis-regulation results from imbalance of cerebrospinal fluid (CSF) production rate (at the choroid plexus epithelial cells) and drainage. Treatments for IIH are limited but weight loss is established as disease modifying.Glucago...

Characterising fat distribution and response to weight loss in idiopathic intracranial hypertension

Ali Fizzah , O'Reilly Michael , Botfield Hannah , Markey Keira , Tomlinson Jeremy , Arlt Wiebke , Sinclair Alexandra

Introduction: Idiopathic intracranial hypertension (IIH) occurs in young obese women (>90%) but little is known about the metabolic characteristics in these patients. We aimed to characterise IIH fat distribution, metabolic phenotype and evaluate alterations following weight loss.Methods: IIH and matched (BMI/sex) healthy obese controls were recruited. Metabolic indices (fasting lipid, glucose, insulin), anthropological measures and body composition ...

The GLP-1R agonist exendin-4 reduces cerebrospinal fluid secretion and intracranial pressure

Botfield Hannah , Uldall Maria , Westgate Connar , Mitchell James , Hagen Snorre , Maria Gonzalez Ana , Hodson David , Jensen Rigmor , Sinclair Alexandra

Background: Current therapies for reducing raised intracranial pressure (ICP) in conditions such as idiopathic intracranial hypertension have limited efficacy and tolerability. As such, there is a pressing need to identify novel drugs. Glucagon-like peptide-1 receptor (GLP-1R) agonists are used to treat diabetes and promote weight loss but have also been shown to affect fluid homeostasis in the kidney. Here, we investigate whether exendin-4, a GLP-1R agonist, is able to modula...

Women with idiopathic intracranial hypertension have a distinct andro-metabolic signature compared to polycystic ovary syndrome and simple obesity

Kempegowda Punith , O'Reilly Michael , Hornby Catherine , Botfield Hannah , Taylor Angela , Hughes Beverley , Tomlinson Jeremy , Arlt Wiebke , Sinclair Alexandra

Context: Idiopathic intracranial hypertension (IIH) is characterised by elevated intracranial pressure and occurs predominantly in obese premenopausal women. Signs and symptoms of polycystic ovary syndrome (PCOS) often coexist in IIH. Here we compared the androgenic and metabolic phenotypes in IIH, PCOS and simple obesity.Patients and Methods: We studied 25 patients with IIH (mean age 34.4±9.2 years; mean BMI 37.8±5.2 kg/m2), in comp...

Androgen excess is highly prevalent in women with idiopathic intracranial hypertension and is biochemically distinct from polycystic ovary syndromes

O'Reilly Michael , Hornby Catherine , Westgate Connar , Botfield Hannah , Markey Keira , Mitchell James , Jenkinson Carl , Gilligan Lorna , Sherlock Mark , Gibney James , Tomlinson Jeremy , Arlt Wiebke , Sinclair Alexandra

Idiopathic intracranial hypertension (IIH) is a condition of unknown aetiology characterised by raised intracranial pressure, chronic headaches and blindness. Akin to polycystic ovary syndrome (PCOS), IIH patients are almost exclusively obese females of reproductive age. A distinct androgen excess profile has been noted in PCOS. Here, we aimed to delineate androgen metabolism in IIH compared to PCOS and simple obesity.Women w...
