Minimizing the initial burst of octreotide acetate based long-acting microspheres by the solvent evaporation method.

Int J Pharm 2022 May 21:121842. Epub 2022 May 21.

Department of Pharmaceutical Sciences and the Biointerfaces Institute, University of Michigan, 2800 Plymouth Road, Ann Arbor, MI 48109; Department of Biomedical Engineering, University of Michigan, 2200 Bonisteel Blvd, Ann Arbor, MI 48109. Electronic address:

Sandostatin long-acting release (SLAR) depot for 1-month controlled release of octreotide is a somatostatin analogue product that has been used extensively in the pharmacological treatment of acromegaly. The complexities in the SLAR coacervation manufacturing processes and the use of a unique glucose-starpoly(lactic-co-glycolic acid) (PLGA-glu) may have contributed to the lack of US FDA-approved generic products referencing SLAR in the USA. To address this challenge, we encapsulated octreotideacetate by commonly used solvent evaporation methodin microspheres of a similar composition to SLAR, including the use of a comparable PLGA-glu.

Biochemical discrepancies in the evaluation of the somatotroph axis: Elevated GH or IGF-1 levels do not always diagnose acromegaly.

Growth Horm IGF Res 2022 May 17;64:101467. Epub 2022 May 17.

Endocrinology Department, Hospital de Santa Maria, Centro Hospitalar Universitário de Lisboa Norte, Lisbon, Portugal; Centre for Endocrinology, William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK. Electronic address:

The most frequent diagnosis underlying the finding of an elevated growth hormone (GH) and insulin-like growth factor-1 (IGF-1) is acromegaly due to a GH-secreting pituitary tumour. However, GH and IGF-1 levels can be discordant in patients with acromegaly due to early or partially treated disease, or there might be another cause of high GH or high IGF-1 unrelated to acromegaly, such as pre-analytical and technical pitfalls, physiological circumstances and pathological conditions. High GH and normal or low serum IGF-1, or alternatively, normal GH with elevated serum IGF-1, should be carefully assessed to avoid misinterpreting the activity of acromegaly or misdiagnosing a patient with acromegaly.

Pituitary MRI Features in Acromegaly due to Ectopic GHRH Secretion from a Neuroendocrine Tumor: Analysis of 30 cases.

J Clin Endocrinol Metab 2022 May 4. Epub 2022 May 4.

Endocrinology and Nutrition Department, Complejo Hospitalario Universitario de Santiago de Compostela, Galicia, Spain.

Context: Ectopic acromegaly is a consequence of rare neuroendocrine tumors (NET) that secrete growth hormone releasing hormone (GHRH). This abnormal GHRH secretion drives growth hormone (GH) and insulin-like growth factor 1 (IGF-1) excess, with a clinical presentation similar to classical pituitary acromegaly. Identifying the underlying cause for the GH hypersecretion in the setting of ectopic GHRH excess is, however, essential for proper management both of acromegaly and the NET. Read More

PaleoFED Team, Unité Mixte de Recherche (UMR) 7194, Centre National de la Recherche Scientifique (CNRS), Département Homme et Environnement, Muséum National d'Histoire Naturelle, Musée de l'Homme, Paris, France.

Gigantism and acromegaly have been observed in past populations; however, analyses usually focus on the morphological features of the post-cranial skeleton. The aim of this study is to characterize the internal anatomical features of the skull (brain endocast anatomy and asymmetry, frontal pneumatization, cranial thickness, sella turcica size) of an adult individual from the 11-14th centuries with these two diseases, in comparison with non-pathological individuals from the same population. The material consisted of 33 adult skulls from a mediaeval population, one of them belonging to an adult female with endocrine disorders (OL-23/77). Read More

Characteristics and treatment outcomes of micromegaly - acromegaly with apparently normal basal GH: A retrospective study and literature review.

Endocr Regul 2022 Apr 30;56(2):87-94. Epub 2022 Apr 30.

Endocrinology Department, Centro Hospitalar Universitario do Porto, Porto, Portugal.

Micromegaly describes a subgroup of patients with clinically evident acromegaly and elevated insulin-like growth factor I (IGF-I) with apparently normal basal growth hormone (bGH) and often a glucose-suppressed growth hormone (GH) of <1 ng/mL at diagnosis. It is controversial whether this condition is a distinct clinical entity or a classic acromegaly in early stages. The aim of the present article was to characterize the prevalence, clinical and biochemical characteristics, and therapeutic outcomes of micromegaly. Read More

Sex difference in patients with controlled acromegaly-A multicentre survey.

Clin Endocrinol (Oxf) 2022 Apr 26. Epub 2022 Apr 26.

Department of Endocrinology, Aarhus University Hospital, Aarhus C, Denmark.

Objective: Active acromegaly is subject to sex differences in growth hormone (GH) and Insulin like growth factor 1 (IGF-I) patterns as well as clinical features but whether this also pertains to controlled disease is unclear.

Design: In a cross-sectional, multi-centre study, 84 patients with acromegaly (F = 43, M = 41), who were considered controlled after surgery alone (n = 23) or during continued somatostatin receptor ligand (SRL) treatment (n = 61), were examined.

Methods: Serum concentrations of GH, insulin, glucose and free fatty acid (FFA) were measured during an oral glucose tolerance test (OGTT) together with baseline serum IGF-I and completion of two HR-Qol questionnaires (acromegaly quality of life questionnaire [AcroQol] and Patient-assessed Acromegaly Symptom Questionnaire [PASQ]).

J Clin Med 2022 Apr 13;11(8). Epub 2022 Apr 13.

Section on Endocrinology & Genetics (SEGEN), Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), National Institutes of Health, Bethesda, MD 20892, USA.

Oral Octreotide: A Review of Recent Clinical Trials and Practical Recommendations for Its Use in the Treatment of Patients With Acromegaly.

Endocr Pract 2022 Apr 19. Epub 2022 Apr 19.

Departments of Medicine and Neurologic Surgery, Mayo Clinic, Jacksonville, Florida.

Objective: Acromegaly is characterized by chronic growth hormone (GH) and insulin-like growth factor 1 (IGF-1) hypersecretion, often caused by a GH-secreting pituitary adenoma. Even though surgery remains the first line of treatment, medical therapy is essential if surgery is contraindicated, does not achieve remission, or does not prevent recurrence despite apparent surgical remission. Oral octreotide capsules (OOCs) that combine octreotide with a transient permeability enhancer technology are the first oral somatostatin receptor ligands (SRLs) approved in the United States for acromegaly.
