The proposed molecular mechanism underlying isolated growth hormone deficiency (IGHD) caused by C53S mutation

Sander Max , Wu Zida , Strasburger Christian J.

Background: Besson A et al. described a patient with homozygous for C53S-hGH suffering from IGHD (JCEM2005 90:2493-9). They observed reduced ability of the mutant to bind and activate GHR in vitro. C53A-hGH lacks the disulfide bond between C53 and C165, which is conserved in GH/prolactin family.Methods: Mouse pituitary AtT-20 cells, HEK-293 and CHO-K1 cells were transfected with plasmids containing C53S, C53A or C53S/C165A cDNA. hGH from cell supernatant...

Medical treatment in adrenal insufficiency: Does the patient’s quality of life differ depending on which glucocorticoid is given?

Bleicken Benjamin , Ventz Manfred , Strasburger Christian J , Quinkler Marcus

Objective: Patients from FRG and West-Berlin with primary (1AI) or secondary (2AI) adrenal insufficiency were treated with hydrocortisone (HC) while in contrast patients from the former GDR received prednisolone (PR). Investigation of our study is to detect any differences in quality of life (QoL) in patients on HC or PR medication.Methods: 350 patients of our outpatient clinic were contacted by mail. Up to now 131 patients took part in the survey. 2 sta...

Longitudinal assessment of response to treatment with oral octreotide capsules in patients with acromegaly: post-hoc analysis of a phase 3 trial

Fleseriu Maria , Melmed Shlomo , Mangal Brian , Strasburger Christian J , Biermasz Nienke R

Introduction: Although biochemical markers of acromegaly disease activity, including GH and IGF1, may fluctuate from day-to-day, biochemical treatment response in clinical trials is generally monitored using single-point analyses. Accordingly, longitudinal evaluations may assess patient status more accurately. In a phase 3 trial, oral octreotide capsules (OOC) demonstrated sustained composite endpoint GH and IGF1 response for ≤13 months in 151 patients with acromegaly pr...

Anthropometric factors have significant influence on the outcome of the GHRH-arginine test – establishment of normative data

Deutschbein Timo , Bidlingmaier Martin , Schopohl Jochen , Strasburger Christian J , Petersenn Stephan

Background: Adult GH deficiency (GHD) is diagnosed by provocative testing of GH secretion. To improve diagnostic accuracy of GHRH plus arginine (GARG) testing, we evaluated the influence of age, BMI, and sex. Furthermore, we aimed to established normative data for an automatic immunoassay specifically measuring 22kD human GH.Methods: Eighty-seven patients with hypothalamic-pituitary disease and 200 healthy controls were enrolled. Controls were prospectiv...

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)

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

vanderLely Aart Jan , Biller Beverly , Brue Thierry , Buchfelder Michael , Ghigo Ezio , Pan kaijie , Jonsson Peter , Lavenberg Joanne , Strasburger Christian J. , Webb Susan , Camacho-Hubner Cecilia , Hey-Hadavi Judith

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...
