Increased serum gamma-glutamyltransferase in hypertriglyceridemia: comparison with serum pseudocholinesterase

Both gamma-glutamyltransferase (gammaGT) and pseudocholinesterase (PCE) were found to be increased in hypertriglyceridemic subjects. High values of gammaGT were noted in alcoholic subjects and especially in those with either increased serum triglyceride or alanine aminotransferase higher than 16 mU/ml, while PCE was not significantly changed in alcoholic subjects. Although both enzymes were strongly correlated with the logarithm of serum triglyceride and the prebeta electrophoretic fraction, there were striking differences concerning their behavior in various hypertriglyceridemic subjects. PCE activity was high even in moderate hypertriglyceridemias but its correlation with serum triglyceride had a tendency to flatten with increasing concentration of triglyceride. However, increase of gammaGT was rather characteristic for gross hypetriglyceridemia. Short-term, triglyceride-lowering therapy was accompanied by a tendency to normalization of gammaGT, while PCE values were not influenced. An attempt was made to interpret these changes of serum-enzyme activity in hypertriglyceridemia in connection with mechanisms of lipoprotein synthesis and with the pathogeny of hyperlipemic conditions.

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.
