The effects of three months of treatment with octreotide on gastric acid hypersecretion induced by hypergastrinaemia were investigated in patients with Zollinger-Ellison syndrome (n = 5) or antral G-cell hyperfunction (n = 4). Gastric acid secretion, fasting plasma gastrin concentrations and clinical findings were examined, and a morphometrical analysis of oxyntic endocrine cells was performed. Administration of octreotide 100 mcg b.d. subcutaneously significantly decreased the volume density of argyrophil cells (P < 0.05) as well as basal and pentagastrin-stimulated acid secretion (P < 0.05). Although partial or complete loss of inhibition was found in most patients after 3 months, gastrin levels were decreased during the first 2 months of treatment (P < 0.05). Fundic D-cells were not affected by treatment. Positive correlations were observed between volume density of argyrophil cells and basal acid output (r = 0.65); plasma gastrin and basal acid output (r = 0.74); plasma gastrin concentrations and volume density of argyrophil cells (r = 0.80). These results support the important role of the enterochromaffin-like cell in maintaining acid secretion, and indicate a specific role for octreotide in the therapy of gastric acid hyp...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.
