Dose interval comparison of Lanreotide Autogel 120 mg in acromegalic patients previously treated with Octreotide LAR

Schopohl Jochen , Badenhoop Klaus , Beuschlein Felix , Droste Michael , Plockinger Ursula , Petersenn Stephan , Strasburger Christian

Acromegalic patients under treatment with Octreotide LAR (Oct), 10, 20 or 30 mg were switched to Lanreotide Autogel 120 mg (Lan) at different dose intervals: 56, 42 and 28 days respectively. Just before the fourth Lan injection, IGF-I values were measured and the dose interval for the final three injections adjusted accordingly: if IGF-I values were between 1 and 2 standard deviations (S.D.) above the age and sex related mean value, no change in dose-interval wa...

Expression and purification of the leptin receptor

Carpenter Byron , Wilkinson Ian , Wu Zida , Strasburger Christian , Artymiuk Peter , Ross Richard

Background: Leptin has multiple functions including modulating energy homeostasis and the immune response. Leptin is an important target for therapy to modulate the immune response in several autoimmune diseases. Although the structure of leptin is known, that of its receptor remains unsolved. The aim of this project was to express and purify the extracellular domain the leptin receptor (ObR) in order to carry out functional and crystallisation studies to elucidate the mechani...

Echo-enhanced ultrasound has a higher sensitivity than high-resolution CT in the detection of hepatic metastasis of adrenocortical carcinoma

Bauditz Jürgen , Wermke Wolfram , Beyersdorff Dirk , Lochs Herbert , Strasburger Christian J. , Quinkler Marcus

Background: Adrenocortical carcinoma (ACC) is a rare and heterogeneous malignancy with incompletely understood pathogenesis and poor prognosis. Computerized tomography (CT) and magnetic resonance imaging (MRI) are routinely performed for imaging of the adrenal mass and for standard staging of chest and abdomen as lung and liver are the primary organs for metastatic spread in ACC. Contrast ultrasound is a non-invasive procedure which has been shown to have a high sensitivity an...

11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) mRNA expression in liver of patients with non-alcoholic steatohepatitis

Konopelska Sarah , Kienitz Tina , Pirlich Matthias , Bauditz Jürgen , Stewart Paul M. , Lochs Herbert , Strasburger Christian J. , Quinkler Marcus

Background: Non-alcoholic fatty liver disease (NAFLD) is recognized as common liver disorder that represents the hepatic manifestation of the metabolic syndrome including visceral obesity, type 2 diabetes, insulin resistance and hyperlipidemia. Non-alcoholic steatohepatitis (NASH) is the progressive form of liver injury with the risk for progressive fibrosis, cirrhosis and end-stage liver disease. The pathophysiology that leads to NAFLD and NASH is not well understood. We hypo...

Abdominal obesity is associated with a decreased hepatic mRNA expression of 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1) in patients with non-alcoholic steatohepatitis (NASH)

Development of an optimal imaging pathway for management of somatotroph tumors in acromegaly

Haberbosch Linus , Macfarlane James , Koulouri Olympia , Gillett Dan , Spranger Joachim , Mai Knut , Cheow Heok , Jones Jonathan , Strasburger Christian , Gurnell Mark

Background: Acromegaly is associated with significant excess morbidity and mortality. Surgery and radiotherapy (including radiosurgery) aim to reduce the burden of growth hormone excess while preserving normal pituitary function, but their effective deployment is dependent on high quality imaging that allows accurate localization of site(s) of active de novo or residual/recurrent disease. Despite the existence of several comprehensive guidelines on the managem...

Serum aryl hydrocarbon receptor-interacting protein (AIP) levels are independent of serum GH levels both at baseline and in dynamic tests of GH stimulation and suppression

Stojanovic Marko , Wu Zida , Stiles Craig , Miljic Dragana , Soldatovic Ivan , Pekic Sandra , Doknic Mirjana , Petakov Milan , Popovic Vera , Strasburger Christian , Korbonits Marta

Background and aim: Aryl hydrocarbon receptor-interacting protein (AIP) is evolutionary conserved and widely distributed throughout organism. Broad interest for AIP comes from involvement of loss-of-function AIP mutations in pituitary adenoma pathogenesis. The role of AIP in normal pituitary function is largely unknown. AIP is co-localized with GH in somatotroph secretory vesicles. Serum AIP protein was proteomically identified. We aimed at investigating whether AIP and GH are...

Long-term treatment with pegvisomant (Somavert®): Observations from 2090 acromegaly patients followed in ACROSTUDY

Introduction: Pegvisomant (PEGV) is approved for the treatment of acromegaly since 2003. This is the second interim analysis of data from ACROSTUDY, with the majority of patients treated for at least five years (yrs).Methods/design: ACROSTUDY is an international, open-label, prospective, non-interventional, post-marketing surveillance study monitoring the long-term safety and efficacy of PEGV. Patients were enrolled in the study on an ongoing basis.<...

Fatigue and subjective complaints in patients with active and controlled acromegaly: a cross sectional multi-center study

Zimmermann Anca , Zwerenz Rudiger , Droste Michael , Schofl Christof , Strasburger Christian J , Plockinger Ursula , Honegger Jurgen , Millaku Bledar , Beutel Manfred E , Weber Matthias M

Introduction: Acromegalic patients (AP) often report fatigue and chronic subjective complaints. We aimed to investigate in more detail these aspects in AP, dependent on disease activity, age, gender, medication and pituitary insufficiency (PI).Patients/methods: Cross sectional, 124 patients (M/W 51/73, age 58.3±14.7 years, 49/75–active/controlled disease). The patients completed the Multidimensional Fatigue Inventory (MFI-20) and the Giessen Su...

Results from the phase 3, randomized, double-blind, placebo-controlled OPTIMAL study of oral octreotide capsules in adult patients with acromegaly

Samson Susan , Nachtigall Lisa , Fleseriu Maria , Gordon Murray , Ludlam William , Patou Gary , Haviv Asi , Molitch Mark E , Biermasz Nienke , Strasburger Christian J , Kennedy Laurence , Melmed Shlomo

Background: Many patients with acromegaly report limitations of long-acting somatostatin receptor ligand (SRL) injections, including ongoing disease symptoms near cycle-end and injection-site pain. Oral octreotide capsules (OOC) may provide an alternative to monthly injections. The phase 3 CHIASMA OPTIMAL study assessed efficacy and safety of OOC in patients with acromegaly controlled on injectable SRLs.Methods: A multinational, randomized, placebo-contr...
