Independent injection vs healthcare-setting administration of somatostatin analogues: A systematic literature review

Luiz Boguszewski Cesar , Korbonits Marta , Artignan Audrey , Martin Garcia Almudena , Houchard Aude , Ribeiro-Oliveira Antonio , W de Herder Wouter

Background: A systematic literature review (SLR) was conducted to assess the use of independent injections (self/partner/home-administered) as an alternative to healthcare-setting injections for chronic diseases. The primary objective was to identify studies reporting on independent injection of somatostatin analogues (SSAs). Comparative evidence on independent injection of other medications was examined as a secondary objective.Methods: MEDLINE/Embase/t...

A systematic literature review to evaluate extended dosing intervals in the pharmacological management of acromegaly

Fleseriu Maria , Zhang Zhaoyun , Hanman Kate , Haria Keval , Houchard Aude , Khawaja Sheila , Ribeiro-Oliveira Antonio , Gadelha Monica

Background: Acromegaly is a rare disorder characterized by excess growth hormone (GH) and insulin-like growth factor 1 (IGF-1). Extended dosing intervals (EDIs) of pharmacological treatments may reduce patient burden and costs compared with standard dosing. This systematic literature review (SLR) investigated treatment of acromegaly at EDIs.Methods: MEDLINE/Embase/the Cochrane Library (2001–June 2021) and key congresses (2018–2021) were searche...

Soluble alpha klotho in adult patients with growth hormone deficiency

Ribeiro de Oliveira Longo Schweizer Junia , Schilbach Katharina , Haenelt Michael , Gagliardo Anica , Stormann Sylvere , Schopohl Jochen , Bidlingmaier Martin

Background: We recently have shown a close association of high concentrations of soluble alpha klotho (sαKL) to disease activity in acromegaly. Small pilot studies suggested that sαKL concentrations might be reduced in GH deficiency (GHD) and increase after recombinant human GH (rhGH) therapy. Our aim was to evaluate the potential of sαKL as a biomarker in GHD.Methods: We evaluated sαKL in comparison to the classical biomarkers GH, IG...

Treatment Patterns in Acromegaly: Analysis of Real-World US Insurance Claims from the MarketScan® Database

Brue Thierry , Fleseriu Maria , Barkan Ariel , Duquesne Edouard , Houchard Aude , del Pilar Schneider Maria , Ribeiro-Oliveira Antonio , Melmed Shlomo K.

Background: Medical treatment for acromegaly (characterized by excess growth hormone [GH] production) includes somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and GH receptor antagonists (GHRAs). However, recent real-world United States (US) treatment evaluations are few. We present treatment patterns for patients receiving medications for acromegaly (1/1/2010–31/7/2022).Methods: De-identified data were extracted from MarketScan&...

Pituitary ACTH Secreting Carcinoma or metastasized Small Cell Pulmonary Carcinoma?

Lopes Sara , Margarida Monteiro Ana , Sa Juliana , Matos Catarina , Machado Catarina , Ribeiro Pedro , Almeida Rui , Marques Olinda

Pituitary carcinomas are rare and represent a challenge in clinical practice. Most secondary tumour localizations are intracranial and spinal, followed by liver, cervical lymph node, bone and, rarely, lung. PC frequently exhibit resistance to most usual therapies and the mean survival time is usually <4 years once metastases have been identified. Ectopic ACTH Syndrome is, in up to 50% cases, caused by lung tumours including carcinoids or Small Cell Lung Carcinomas (SCLC). ...

Levothyroxine dosing following bariatric surgery – A 4-year follow up

Ribeiro Sara , Lima Bruno A , Goncalves Juliana , Moreno Telma , Ferreira Helena Urbano , Pedro Jorge , Varela Ana , Carvalho Davide , Freitas Paula

Introduction: The anatomical and physiological changes induced by bariatric surgery (BS) can significantly impact the absorption and pharmacokinetics of orally administered medication. In particular, levothyroxine (LT4) dosage, given its dependence on patient’s weight and gastric pH for optimal absorption, is expected to change following BS. However, the literature is not unanimous and there is a void of longer-term studies. We aimed to compare LT4 dosage 4 years followin...

Folate: a new player in metabolic syndrome?

Paredes Silvia , Alves Marta , Pereira Maria Lopes , da Costa Jose Maia , Fernandes Aline , Manso Fernando , Marques Olinda , Ribeiro Laura

Introduction: Bariatric surgery (BS) candidates display several nutritional deficiencies that can aggravate after surgery. Metabolic syndrome (MS) is a cluster of cardiovascular risk factors with several disturbed metabolic pathways. Therefore, individuals with MS submitted to BS are probably more prone to nutritional deficiencies.Objective: To evaluate the prevalence of nutritional deficiencies and eventual differences between BS candidates with and wit...

Evolution of body composition 3 years after sleeve gastrectomy

Paredes Silvia , Alves Marta , Pereira Maria Lopes , da Costa Jose Maia , Fernandes Aline , Manso Fernando , Marques Olinda , Ribeiro Laura

Background: Sleeve gastrectomy (SG) has effective results on weight loss, which should result from fat mass loss and efforts should be made to preserve lean mass. Few studies have evaluated body composition (BC) changes after SG for periods >2 years.Objective: To investigate the impact of SG on weight and BC, comparing by gender.Materials and methods: Retrospectively, databases of patients who underwent SG between 2011 and 2013...

The Drosophila AIP orthologue is essential for actin cytoskeleton stabilisation and cell adhesion

Aflorei Elena Daniela , Klapholz Benjamin , Moderau Nina , Baptista-Ribeiro Paulo , Tapon Nic , Brown Nick , Stanewsky Ralf , Korbonits Marta

Introduction: Tumours with aryl hydrocarbon receptor interacting (AIP) mutations often show an unusually aggressive and invasive clinical course as up to 80% of AIP positive pituitary adenomas have a certain degree of extrasellar extension. The exact mechanisms by which AIP inactivation promotes an aggressive behaviour remain unknown. The majority of adenohypophysis is composed of sinuous cords of epithelial cells and consequently, molecules that can induce remodellin...

Sarcopenia, more that dehydration, may be associate to underweight Portuguese centenarians

Silva Alda Pereira da , Matos Andreia , Valente Ana , Gil Angela , Alonso Isanete , Ribeiro Ricardo , Clara Gorjao , Bicho Manuel

Introduction: Fat-free mass has a functional significance in aging. The objective of this study was to evaluate the prevalence of underweight in a Portuguese population of centenarians and their relationship with dehydration or sarcopenia.Methods/design: Anthropometric data were obtained using standard procedures from 252 centenarians (100.26±1.99 years), 77.8% women (W). Body composition was assessed by tetrapolar bioimpedance. It was considered de...
