Aldo-keto reductase (AKR) 1C1 – a potential driver of cell cycle progression in hepatocellular carcinoma

da Conceição Ismael , Nikolaou Nikolaos , Arvaniti Anastasia , Gathercole Laura , Hodson Leanne , Tomlinson Jeremy

The health burden associated with non-alcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, continues to escalate. Not only is NAFLD associated with significant liver-specific and cardiovascular morbidity and mortality, but patients are at risk of the development of hepatocellular carcinoma (HCC); a malignancy where the incidence continues to rise and there are very limited therapeutic strategies.Aldo-keto reductase ...

The american lifestyle induced obesity syndrome (ALIOS) diet induces an increase in intestinal permeability and exacerbates inflammation in female and male mice via the TLR4 signalling pathway

Anastasia Arvaniti , Nikolaou Nikolaos , Harris Shelley , Cox Roger , Corridoni Daniele , Xin Wei , Tomlinson Jeremy , Gathercole Laura

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease spanning from simple steatosis to non-alcoholic steatohepatitis (NASH) with risk of progression to fibrosis and eventually cirrhosis. Dysfunction of the gut-liver axis plays a role the progression to NASH. Intestinal damage and increased permeability can increase the delivery of pathogen-associated molecular patterns (PAMPs), such as LPS and intact bacteria, to the liver where they can activate the TLR4 signall...

Androgens potently regulate sterol 12α-hydroxylase (CYP8B1) expression in mouse and human liver

Potter Tom , Gangitano Elena , Visser Jenny , Gathercole Laura , Tomlinson Jeremy , Nikolaou Nikolaos

Polycystic ovarian syndrome (PCOS) is one of the most common endocrine disorders affecting 6-15% of women of reproductive age. The syndrome is characterised by a variety of reproductive and metabolic features, including hyperandrogenism, chronic anovulation and hirsutism as well as insulin resistance, dyslipidaemia, and non-alcoholic fatty liver disease (NAFLD). Specifically regarding NAFLD, androgen excess is hypothesised to have a direct effect on hepatic lipid storage, thus...

Glucagon tolerance tests in a tertiary paediatric centre: an evidence-base for protocol refinement

Farley Hannah , Gilbert Jennifer , Daskas Nikolaos

Background: The glucagon tolerance test (GTT) is used to diagnose growth hormone deficiency (GHD) in younger children or in patients where the insulin tolerance test is contraindicated. We assessed GTTs carried out over five years in a tertiary paediatric centre to assess growth hormone (GH) and cortisol axes. The aim was to assess at which time points the GH peak was observed, and assess whether any predictive value is gained from demographics or IGF-1....

Can pericardial effusion be a manifestation of Graves' disease? An unusual case

Besis George , Kyriakakis Nikolaos , Premawardhana Lakdasa D

Introduction: Graves’ disease (GD) is associated with a number of cardiovascular complications, including rhythm disturbances, mitral valve prolapse, pulmonary hypertension and heart failure. Pericardial effusion in the context of GD has only been reported in a small number of cases.Case: A 59-year-old gentleman presented with a 3-day history of dyspnoea and pleuritic chest pain. He had a previous history of GD 8 months ago, pulmonary embolism (PE),...

GH neuro-secretory dysfunction following traumatic brain injury in childhood

Daskas Nikolaos , Sharples Peta , Crowne Elizabeth

GH deficiency is recognised as a complication of adult traumatic brain injury (TBI) but there are conflicting data in children possibly due to the influences such as age at TBI, trauma mechanism but also by timing, method and criteria of hormonal evaluation.Objectives: To assess the long-term impact of TBI on the GH–IGF1 axis following TBI in childhood.Patients: Longitudinal study of 28 participants with a history of moderate/...

From EFOS to ExFOS: any news with teriparatide prescription habits in Greece?

Aloumanis Kyriakos , Papaioannou Nikolaos , Dimopoulos Nikolaos , Kioumourtzi Vassiliki , Drossinos Vangelis , Kapetanos George

Purpose: Extended Forsteo Observational Study (ExFOS), a multinational, non-interventional, prospective, observational study to evaluate fracture outcomes, back pain, compliance and health-related quality of life in osteoporotic male and female patients treated with teriparatide (TPTD), has followed European Forsteo Observational Study (EFOS) on postmenopausal women, aiming to provide more data on the effect of the extension of treatment duration from 18 to 24 months and the n...

Predictors of incidental parathyroidectomy during thyroid surgery

Michalopoulos Nikolaos , Alevizos Leonidas , Markogiannakis Haridimos , Memos Nikolaos , Giannopoulos Aggelos , Malachtari Sofia , Kekis Panagiotis , Manouras Andreas

Objective: To identify incidental parathyroidectomy predictors in thyroid surgery.Methods: All thyroid operations during 4 years were reviewed (n=1010). Patients were divided in those with (parathyroidectomy group) and without incidental parathyroidectomy (no-parathyroidectomy group).Results: Incidental parathyroidectomy occurred in 198 patients (19.6%). The groups were comparable in age, thyroid weight and pathology, hypert...

Thyroid surgery with the new harmonic scalpel: a prospective randomized study

Alevizos Leonidas , Michalopoulos Nikolaos , Markogiannakis Haridimos , Memos Nikolaos , Tsamis Dimitrios , Linardoutsos Dimitrios , Kekis Panagiotis , Manouras Andreas

Background-objective: Although the harmonic scalpel has been shown to be safe and effective in thyroid surgery, several surgeons consider the previously available instruments to be large and cumbersome, especially in terms of dissection capabilities. To this context, an innovative technical improvement of the device for thyroid surgery has very recently been implemented and has been made available in 2008. Utilization of this new device, however, has not been evaluated in any ...

5β-reductase is downregulated in patients with non-alcoholic fatty liver disease and hepatocellular carcinoma and controls metabolic and proliferative phenotype through LXR-dependent mechanisms

Nikolaou Nikolaos , Arvaniti Anastasia , Sanna Fabio , Saikali Michael , da Conceicao Ismael , Dempster Niall , Gathercole Laura , Cummins Carolyn , Tomlinson Jeremy

Non-alcoholic fatty liver disease (NAFLD) is a spectrum of disease ranging from simple intrahepatic lipid accumulation to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). 5β-reductase (AKR1D1) is a liver enzyme that catalyses a fundamental step in bile acid (BA) synthesis. Both BAs and BA intermediates are established as potent regulators of metabolic and proliferative phenotype. We have hypothesised that AKR1D1 plays a crucial regulatory role in NAFLD and HCC. Hu...
