The role of amino-acid transmitters in the pathogenesis of delirium tremens: a brief report

Abstract

The importance of serum levels of amino-acid neurotransmitters and of relevant enzymes has not been adequately evaluated in alcoholics. It is hypothesized that several of these neurotransmitters would be likely to be elevated in alcoholics overall, those with alcoholic withdrawal and, especially, individuals undergoing severe withdrawal as might be seen in delirium tremens (DTs). The subjects for these evaluations (N = 106 men) were 46 hospitalized patients with DTs, 20 subjects with an alcohol withdrawal syndrome (AWS) in the absence of DTs, 20 alcohol-dependent individuals not demonstrating withdrawal (ADS) and 20 nonalcoholic controls. The analyses evaluated the serum levels of glutamate (Glu), aspartate (Asp), gamma-aminobutyric acid (GABA) and glycine (Gly), as well as the activity of the relevant enzymes glutamic acid decarboxylase (GAD) and GABA transaminase (GABA-T). In these analyses, the subjects with DTs had significantly lower serum values for Gly and GAD, as well as for GABA, while demonstrating elevated values for Asp and Glu. These data support the possibility that some of the symptoms of alcohol withdrawal, especially DTs, may be related to an altered balance between neurotoxic, or excitatory, and inhibitory ami...Continue Reading

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.
