Audit on continuous subcutaneous insulin infusion (insulin pump) therapy

Argentesi Giulia , Yahia Seifeledin , Gazis Anastasios

Objectives: Insulin pumps were introduced in the late 1970s. Their use has continued to grow and the technology has continued to improve along with the development of insulin substrates. They are however a costly therapy, thus NICE recommend pump therapy in the following circumstances; when patients are undergoing regular episodes of severe and sometimes unpredictable episodes of hypoglycaemia, have HbA1c levels over 8.5% despite attempts to lower it, difficult control during ...

Double somatic mutations of CTNNB1 and GNA11 in aldosterone producing adenomas (APAs) presenting in puberty, pregnancy or menopause

Objective: We reported 3 patients with primary aldosteronism who presented at times of high plasma LH, and had somatic CTNNB1 mutations causing ˜100-fold elevation of LHCGR in their APAs (Teo et al. NEJM 2015). Subsequently we identified 4 further patients, but the association with pregnancy was not found by others. Whole exome sequencing (WES) of an APA diagnosed at onset of puberty suggests an explanation.Method: WES of tumour and blood w...

Endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) as an alternative to left sided adrenalectomy in the treatment of primary aldosteronism

Wu Xilin , Ney Alexander , Cheow Heok , Goodchild Emily , Argentesi Giulia , Chung Teng-Teng , Drake William , Pereira Stephen , Brown Morris

Primary aldosteronism (PA) is the cause of 5–10% of hypertension, surgically curable in patients with unilateral aldosterone-producing adenomas (APAs). However <1% of patients are currently diagnosed and cured. Newer and simpler modalities of diagnosis and treatment are required. The aim of FABULAS (a feasibility study of endoscopic ultrasound-guided ablation as a non-surgical, adrenal sparing treatment for aldosterone-producing adenomas) is to determine in 30 patient...

A 65-year-old Afro-Caribbean gentleman, with a >10-year history of hypertension, frequently recorded blood pressures of >160/80 mmHg. His serum electrolytes showed Na+ 145 mmol/l and K+ 3.2 mmol/l. MRI demonstrated 13 mm left medial-limb adrenal adenoma. His hypertension was uncontrolled on treatment with amlodipine 10 mg OD, spironolactone 50 mg OD, losartan100 mg OD and doxazosin 16 mg OD. Although his quality of life was reduced, and he dislike...

Method of venesection and location of peripheral sample alter adrenal venous sampling results and interpretation in primary aldosteronism

Introduction: Adrenal venous sampling (AVS) is the criterion standard method of lateralisation in primary aldosteronism (PA). Despite this pivotal role, there is limited consensus and significant variability between centres related to many of the technical aspects of AVS. In this study, we sought to address whether variations in two different technical aspects of AVS altered parameters and interpretation, namely: 1. Peripheral sample site 2. Method of adrenal vein (AV) venesec...

Somatic mutations of GNA11 and GNAQ in CTNNB1-mutant aldosterone-producing adenomas presenting in puberty, pregnancy or menopause.

Most aldosterone-producing adenomas (APAs) have gain-of-function somatic mutations of ion channels or transporters. However, their frequency in aldosterone-producing cell-clusters of normal adrenals could suggest the existence of co-driver mutations which influence the development or phenotype of APAs [1]. Gain-of-function mutations in both CTNNB1 and the G-protein coupled receptor GNA11 were found by whole exome sequencing in 3/10 APAs. Further sequencing of...

Primary results from MATCH: A randomised controlled trial in primary aldosteronism

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...
