Frequent heavy use of alcohol depletes transferrin of carbohydrate moieties that are normally attached to it. Determination of Carbohydrate-deficient Transferrin Using Capillary Zone Electrophoresis Birgitte Wuyts,1 Joris R. Delanghe,1* Ishmael Kasvosve,2 Annick Wauters,3 Hugo Neels,4 and Jacques Janssens5 Background: Current methods for carbohydrate-defi-cient transferrin (CDT) often suffer from low precision, complexity, or risk of false positives Carbohydrate-deficient transferrin (CDT) and γ-glutamyltransferase (GGT) are commonly used markers of alcohol consumption. High levels of GGT have been  Transferrin comprises a single polypeptide chain with two polysaccharide chains ended by a sialic acid residue.

Transferrin är en polypeptid som består av 2 N-länkade polysackaridkedjor,  av P Wennberg · Citerat av 1 — The alcohol use disorders identification test (AUDIT) and carbohydrate-deficient transferrin (CDT) in a routine workplace health examination.

Alcohol inhibits the glycosylation of several glycoproteins, including transferrin.

Test Indications: Carbohydrate-deficient transferrin is a marker for the autosomal recessive disorder previously known as carbohydrate deficient glycoprotein syndrome (CDGS). CDGS is caused by various defects involving the glycosylation of glycoproteins. Carbohydrate-deficient transferrin (CDT), indicating collectively the glycoforms of human transferrin with 0-2 terminal sialic acid residues, namely asialo-, monosialo- and disialotransferrin, is considered the most specific biochemical marker for detecting chronic alcohol abuse and for monitoring abstinence during treatment (1).

Carbohydrate deficient transferrin

It contains two carbohydrate residues and two N –linked glycans (MacGillivray et al. 1983). Six sialic acid moieties may be attached. Carbohydrate deficient transferrin (CDT)can be used to assess a patient's chronic alcohol consumption. The test does not correlate with the amount of alcohol consumed, but relates to the prolonged consumption of large quantities of alcohol. A single episode of heavy drinking will not elevate CDT levels.

Carbohydrate-deficient transferrin (CDT) refers to changes in the microheterogeneity of the iron transport glycoprotein transferrin that are seen after prolonged heavy drinking [99]. Initial studies revealed structural changes in transferrin in both CSF and serum of alcoholic patients [100] , and these abnormalities were also demonstrated to normalize during periods of abstinence. Carbohydrate-deficient transferrin (CDT) is a biomarker for chronic alcohol intake of more than 60 g ethanol/d. It has been reported to be superior to conventional markers like gamma-glutamyltransferase (GGT) and mean corpuscular volume MCV).

For those who abuse alcohol, these side-chains drop to 0 – 2. This is why it is called a carbohydrate deficient transferrin. Carbohydrate Deficient Transferrin Transferrin is a carbohydrate-protein that relates and carries Fe ions through the blood. In healthy normal individuals, transferrin has specific sialic acid arrangement through its molecule. The sialic acid component of CDT might range from four to six per molecule.
