Associations of Insulin-like growth factor-II with cardiovascular risk have been inadequately studied. We studied longitudinal associations of IGF-II with cardiovascular risk factors in people with type 2 diabetes. Subjects and methods: 462 type-2 diabetes patients aged 26 to 86 years from the Salford Diabetes cohort were analysed. Longitudinal clinical information was extracted (years 2002–2009) from an integrated database of primary care and hospital data. IGF-II was me...

Insulin-like growth factors have fundamental roles in metabolism and apoptosis. Circulating IGF-I and IGF-II are primarily sequestrated with IGFBP-3 in ternary complexes with the acid-labile subunit. We hypothesized that polymorphisms of the IGFBP3 gene may impact circulating IGF-II concentrations.Methods: 478 Caucasian patients were selected from the Salford Diabetes Cohort for analysis. Thirteen haplotype tagging single nucleotide polymorphisms (SNPs) ...

Acromegaly is associated with increased morbidity and mortality. Surgical excision of the adenoma remains the best option to attain a cure. The results of surgery in the region were unsatisfactory compared to other European centres as was amply borne out in a 1998 review. As the lack of a dedicated pituitary surgical team was considered contributory, one was developed offering Endoscopic, transsphenoidal, pituitary surgery and their results audited.Sixte...

Surgery is the treatment of choice for GH secreting tumours. Recent papers suggest, early re-exploration of persistently active tumours may be beneficial. Endocrine assessment, to confirm cure, in the immediate post-operative period is difficult. We aimed to ascertain which test of GH excess performed post-operatively is a reliable predictor of longer term cureMethods: 16 consecutive patients (8 males and 8 females: mean age 46.8±13 years) with acti...

Introduction: Dysregulation of the insulin-like Growth Factor (IGF) system and particularly IGF-I and IGF binding protein-1 (IGFBP-1) has been implicated in the pathogenesis of obesity, diabetes mellitus and its complications such as cardiovascular disease and nephropathy, but relatively little is known about the genomics of the IGF system in health and disease.Methods: Six single nucleotide polymorphisms (SNPs) were genotyped in the IGFBP-1 gene, in a r...

AimsThe increasing incidence of type 2 diabetes mellitus with age in the context of ageing populations worldwide highlights the need to understand better factors that influence glucose homeostasis. Our hypothesis was that lifestyle change accompanying migration influences the relationship between pancreatic beta cell function (HOMA-B) and age.MethodsWe compared a specific migrant Gujarati community in Britain...

IntroductionWe have previously shown that patients with pituitary Cushing's have impaired quality of life vs. other pituitary tumour groups. Whether this is related to direct neural effects of excess ACTH or cortisol is uncertain. In order to address this, we compared patients who had undergone definitive treatment for pituitary vs adrenal Cushings.DesignWe assessed 14 patients with biochemically cured pituit...

IntroductionThe IGF-system has also been implicated in the pathogenesis of diabetes and cardiovascular disease. We report the effects of total energy intake on the IGF-system in two populations with a markedly different dietary macronutrient intake and cardiovascular event rate.MethodDietary macronutrient intake was measured in a specific Gujarati migrant community in Sandwell UK (n=205) compared with people ...

Background: Bariatric surgery (BS) results in metabolic pathway recalibration. When major metabolic change occurs, blood protein components have a key role and can be altered significantly. We set out to identify potential biomarkers of change in plasma following BS in people achieving remission of type 2 diabetes mellitus (T2DM).Methods: Longitudinal analysis was performed on serum samples from 10 individuals who all achieved remission of T2DM following...

Background: Bariatric surgery (BS) can have significant effects on multiple body systems and has been an effective intervention for morbid obesity, improving many comorbid medical conditions that are associated with mental health and cognitive dysfunction. It was previously shown that cognitive impairment was partly reversible in obese patients after BS [1], however, the effects of BS on proteins associated to central nervous system (CNS) still unknown. We evaluated if there a...
