Adrenergic blockade in subarachnoid haemorrhage

Acta neurochirurgica
M M Cameron, R H Haas

Abstract

Over the last 15 years progressive interest has developed in the relationship between subarachnoid haemorrhage, sympathetic nervous system over-activity and the genesis of cerebral artery spasm. Following on from earlier work, vide infra, suggesting that adrenergic blockade might influence the course and prognosis of patients with subarachnoid haemorrhage, two double blind trials have recently been completed in Southampton. The first trial attempted to establish whether or not a single intracarotid injection of phenoxybenzamine improved the mortality and late morbidity of patients with subarachnoid haemorrhage. Results suggested that it did not. The second trial, comprising two groups of 50 patients each, attempted to assess the influence of prolonged treatment with propranolol on the course and prognosis of these subarachnoid haemorrhage patients. Early results suggest that, as with the alpha-blocker, the mortality and severe morbidity was not improved by beta-adrenergic blockade.

COVID-19

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.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
