Metabolic effects of amino acid solutions infused for renal protection during therapy with radiolabelled somatostatin analogues.
BACKGROUND Infusion of amino acids (AAs) can reduce renal uptake of radiolabelled somatostatin analogues resulting in a lower kidney exposure during peptide radiotherapy of patients with neuroendocrine tumours. In this study, we investigated the metabolic effects related to the infusion of large amounts of amino acids in patients undergoing positron emission tomography (PET) studies with [(86)Y...
متن کاملTreatment of advanced neuroendocrine tumours with radiolabelled somatostatin analogues.
Neuroendocrine tumours (NETs) constitute a heterogeneous group of tumours that frequently express cell membrane-specific peptide receptors, such as somatostatin receptors (SSTRs), and of which gastroenteropancreatic (GEP), carcinoid and pancreatic islet cell tumours exhibit the highest expression of SSTRs. Radiolabelled receptor-binding somatostatin analogues (octreotide and lanreotide) act as ...
متن کاملRegulation of renal amino acid transporters during metabolic acidosis.
The kidney plays a major role in acid-base homeostasis by adapting the excretion of acid equivalents to dietary intake and metabolism. Urinary acid excretion is mediated by the secretion of protons and titratable acids, particularly ammonia. NH(3) is synthesized in proximal tubule cells from glutamine taken up via specific amino acid transporters. We tested whether kidney amino acid transporter...
متن کاملSomatostatin Analogues for Receptor Targeted Photodynamic Therapy
Photodynamic therapy (PDT) is an established treatment modality, used mainly for anticancer therapy that relies on the interaction of photosensitizer, light and oxygen. For the treatment of pathologies in certain anatomical sites, improved targeting of the photosensitizer is necessary to prevent damage to healthy tissue. We report on a novel dual approach of targeted PDT (vascular and cellular ...
متن کاملSomatostatin and somatostatin analogues: pharmacokinetics and pharmacodynamic effects.
Somatostatin is a 14 amino acid peptide that inhibits pancreatic exocrine and endocrine secretion. Its clinical application has been limited by its very short half life, necessitating continuous intravenous infusion. Octreotide is an 8 amino acid synthetic analogue of somatostatin that possesses similar pharmacological effects. It has a much longer duration of action, however, and can be given ...
