Genetics and diagnostic characterisation of bladder paragangliomas

Rafique Shaina , Surendran Aarthi , Joshi Mamta , Breen Louise , Velusamy Anand , Izzat Louise , McGowan Barbara , Powrie Jake , Carroll Paul V

Bladder Paragangliomas (PGLs) are a rare manifestation of sympathetic chain PGLs and occur in prone patients with SDH mutation.They often display an aggressive phenotype with metastatic disease and require long-term follow up. SDHB immunostaining plays a significant role in initial risk stratification and facilitating appropriate genetic testing. We report four cases illustrating diagnostic management and outcome issues in this rare neuroendocrine pathology; two with SDHB muta...

Unaffected genetic testing in families at risk of phaeochromocytoma or paraganglioma

Izatt Louise , Carroll Paul , McGowan Barbara , Powrie Jake , Moonim Mufaddal , Jacques Audrey , Obholzer Rupert , Whitelaw Benjamin , Kumar Ajith , Akker Scott

75% of patients presenting with a phaeochromocytoma (PCC) or paraganglioma (PGL) have no relevant family history, but a germline pathogenic variant is identified in 30–40%. In our genetic endocrine clinic, over 80% of patients with malignant PCC or PGL have SDHA/SDHB/SDHC/SDHD/MAX or FH pathogenic variants identified, confirming high heritability in severe disease.We describe a series of seven patients from fiv...

Mutational analysis and SDHB immunostaining in bladder paraganglioma

Rafique Shaina , Surendran Aarthi , Joshi Mamta , Breen Louise , Velusamy Anand , Izatt Louise , McGowan Barbara , Powrie Jake , Carroll Paul V

Bladder Paragangliomas (PGLs) constitute < 1% of all bladder tumours and 5% in our patient cohort of 80 patients with tumours due to SDH deficiency. They often display an aggressive phenotype with metastatic disease and require long-term follow up. SDHB immunostaining plays a significant role in initial risk stratification and facilitating appropriate genetic testing. We present four cases of bladder PGLs; two with SDHB mutation, one SDHA and one is awaiting extended genet...

HPA axis suppression in patients treated with glucocorticoids: relationship to dose, duration and likelihood of recovery

Gregori Maria , Carroll Paul , Thakali Sonu , Breen Louise , Velusamy Anand , McGowan Barbara , Kariyawasam Dulmini , Tremble Kathryn , Saqib Aaisha

Background: Tertiary adrenal insufficiency (TAI) is a complication of long-term exogenous steroid use which results in suppression of the hypothalamic-pituitary-adrenal (HPA) axis. The short synacthen test (SST) is used to assess HPA axis function and recovery during glucocorticoid weaning. This study examined the effect of steroid preparation, dosage and therapy duration on HPA axis suppression.Method: A retrospective analysis of 950 SSTs performed betw...

Somatostatin analogue treatment is associated with lack of progression of pNETs <20mm in size in patients with MEN1

Frizelle Isolda , Velusamy Anand , McGowan Barbara , Breen Louise , Duncan Emma , Izatt Louise , Christodoulou Dimitra , Joshi Mamta , Paul Carroll

Introduction: Pancreatic neuroendocrine tumours (pNETs) are the main cause of mortality in patients with multiple endocrine neoplasia type 1 (MEN1). The CLARINET study demonstrated that somatostatin analogue treatment improved progression free survival in patients with enteropancreatic NETs but little is known about the role of SSA in preventing progression of pNETs in MEN1 (1). Many centres have started using SSA treatment in MEN1 patients with enlarging pNETs or tumours &#62...

Genetic mutations in bladder paragangliomas - not just SDHB-related disease

Anandappa Samantha , Breen Louise , Thurairaja Ramesh , Christodoulou Dimitra , Jacques Audrey , Velusamy Anand , McGowan Barbara , Izatt Louise , Carroll Paul

Bladder Paragangliomas (PGLs) are rare forms of neuroendocrine tumours arising from sympathetic paraganglionic tissue. They account for <1% of all Pheochromocytomas and Paragangliomas (PPGLs) and < 0.06% of all bladder tumours. All patients with PPGLs are recommended to be considered for genetic testing as ~ 40% of PPGLs are associated with a germline mutation, even if there is no prior family history of disease. Identifying an inherited PPGL predisposition has importa...

Venous glucose levels, peak GH and peak cortisol during Insulin Tolerance Test using 0.15 UNITS/Kg and 0.1 UNITS/Kg body weight

Yeoh Phillip , Grossman Ashley , Chew Shern L , Bouloux Pierre , Khoo Bernad , Carroll Paul , Aylwin Simon , Baldweg Stephanie

Insulin Tolerance Test (ITT) is a procedure commonly done by Endocrine Specialist Nurse in endocrine department. We look at over 120 ITT results done in 2 endocrine centres using Insulin Actrapid 0.15 UNITS/kg and 0.10 UNITS/kg dose plotting the glucose levels at 30, 45 and 60 min. We also look at peak GH and peak cortisol on each of these groups.Aims: We wanted to know how many percentage of patients achieving hypoglycaemia below 0.5 mmol/l, 0.5–1....

Whole exome sequencing in congenital hypogonadotropic hypogonadism

Izatt Louise , Carroll Paul , Lillis Suzanne , Brodd Lina , Stone Kristina , Ryan Kevin , Ahn JooWook , Simpson Michael , Yau Michael

Congenital hypogonadotropic hypogonadism (CHH (MIM161110)) due to GnRH deficiency is a rare genetic disorder (affects ~1/30 000) characterised by abnormal pubertal development and infertility. Over 60% cases have anosmia (Kallmann syndrome) and some exhibit additional phenotypes. CHH is a genetically heterogeneous developmental disease. Most cases present sporadically, although familial forms (AD, AR, and X-linked) with incomplete penetrance and variable expressivity occur. Re...
