Patients with acromegaly die prematurely from CVD. Hypertension is more prevalent with increased peripheral vascular resistance thought to be due to structural remodelling of resistance vessels.We investigated structural properties and reactivity of small arteries in 20 healthy controls(55±11 years, 10 m) and 43 patients with acromegaly (55±14 years, 29 m), split into active disease (AD, n=17, 56±15 years, 13 m) or remission (CD, <i...

Introduction: Data are conflicting on whether and how serum adipokines alter following acute dietary intake. Here, we used the specific challenge of standard 75 g glucose tolerance tests (GTT) to assess timed changes in TNF-α, IL-6, leptin and adiponectin in healthy younger women and how these would be affected by adiposity.Methods: Consenting participants in the Manchester Mothers’ Heart and Vascular health study had serum adipokines measured ...

Introduction: IGF-I and its binding proteins may modulate cardiovascular risk. As part of our Manchester Mothers’ Cardiovascular study, we tested in pre-menopausal women the hypothesis that higher circulating IGF-I concentrations would be associated with lesser arterial stiffness and lower cardiac (LV) mass, while higher IGFBP1, reflecting less pre-hepatic insulin, would be positively related to small vessel function.Methods: About 193 women aged 32...

Background: After adrenalectomy (ADX) for primary aldosteronism (PA), approximately 30% of patients achieve clinical success (normalisation of home BP); many additional patients report feeling subjectively better. We used the non-randomised MATCH study1 to further assess quality of life (QoL) changes in participants.Objective: Assess QoL using the 36-item Short Form Health Survey (SF-36) after surgical treatment of unilateral PA and medical treatment of ...

Introduction: Our MATCH study demonstrated 11-C ligand MTO was non-inferior to adrenal vein sampling in predicting surgical outcomes of adrenalectomy in patients with PA. The 20-min half-life of 11-C imposes logistic constraints. We investigated an 18-F ligand, CETO; its 2h half-life permits use in any facility with fluorodeoxyglucose (FDG)-positron emission tomography (PET) scan capability.Objective: To compare the detection of aldosterone-producing ade...

Primary aldosteronism (PA) is considered the sole, often curable, cause of hypertension in 5–10% of patients. Yet there has been only one RCT, and practice has changed little since the advent of CT scanning. Adrenal vein sampling (AVS) and adrenalectomy remain the standard, invasive interventions, leading to a 50% reduction in pill count as the average clinical improvement.Study DesignIn MATCH (Is Metomidate PET-CT superior t...

Introduction: In a prospective within-patient study (MATCH) 11C-metomidate PET-CT (MTO) was an accurate non-invasive alternative to adrenal vein sampling in the detection of unilateral PA1. Post-adrenalectomy (ADX), 24/78 (30%) patients achieved complete clinical success (PASO consensus) at 6 months, but 75% achieved reduction in B-type natriuretic peptide (BNP).Aim: To determine: 1. the number of patients who sustain complete clinical success...
