Red blood cell enzyme abnormalities in patients treated with chemotherapy. 1979

J Etiemble, and J F Bernard, and C Picat, and D Belpomme, and P Boivin

Sxiteen red blood cell enzyme activities and fetal haemoglobin level have been assayed in 60 patients treated for haematologic or nonhaematologic malignant diseases with various combinations of cytostatic drugs. Acquired enzyme deficiency was found in 20 patients. The most frequently decreased activities were those of G6PD (12 cases), PK (seven cases), PFK (six cases) and AK (three cases). In many patients decreased activity of some enzymes contrasted with increased activity of others such as ALD, TPI, G3PD, PGK, ENOL and 6PGD. The number of abnormalities seems to be related to the duration of the treatment. Incidence of enzyme deficiencies was similar in patients previously treated or not with radiotherapy. Enzyme abnormalities were correlated neither with haemoglobin level nor with reticulocyte count. They were very similar to those observed in primary acquired dyserythropoietic and preleukaemic states. Their prognostic value and mechanism are discussed.

UI	MeSH Term	Description	Entries
D009369	Neoplasms	New abnormal growth of tissue. Malignant neoplasms show a greater degree of anaplasia and have the properties of invasion and metastasis, compared to benign neoplasms.

D012156	Reticulocytes	Immature ERYTHROCYTES. In humans, these are ERYTHROID CELLS that have just undergone extrusion of their CELL NUCLEUS. They still contain some organelles that gradually decrease in number as the cells mature. RIBOSOMES are last to disappear. Certain staining techniques cause components of the ribosomes to precipitate into characteristic "reticulum" (not the same as the ENDOPLASMIC RETICULUM), hence the name reticulocytes.	Reticulocyte
D004359	Drug Therapy, Combination	Therapy with two or more separate preparations given for a combined effect.

D004798	Enzymes	Biological molecules that possess catalytic activity. They may occur naturally or be synthetically created. Enzymes are usually proteins, however CATALYTIC RNA and CATALYTIC DNA molecules have also been identified.	Biocatalyst,Enzyme,Biocatalysts

D004912	Erythrocytes	Red blood cells. Mature erythrocytes are non-nucleated, biconcave disks containing HEMOGLOBIN whose function is to transport OXYGEN.

D005319	Fetal Hemoglobin	The major component of hemoglobin in the fetus. This HEMOGLOBIN has two alpha and two gamma polypeptide subunits in comparison to normal adult hemoglobin, which has two alpha and two beta polypeptide subunits. Fetal hemoglobin concentrations can be elevated (usually above 0.5%) in children and adults affected by LEUKEMIA and several types of ANEMIA.	Hemoglobin F,Hemoglobin, Fetal
