Temporal sequence of major biochemical events during blood bank storage of packed red blood cells.

چکیده
BACKGROUND We used sensitive spectroscopic techniques to measure changes in Band 3 oligomeric state during storage of packed red blood cells (RBC); these changes were compared to metabolic changes, RBC morphology, cholesterol and membrane protein loss, phospholipid reorganisation of the RBC membrane, and peroxidation of membrane lipid. The aim of the study was to temporally sequence major biochemical events occurring during cold storage, in order to determine which changes may underlie the structural defects in stored RBC. MATERIALS AND METHODS Fifteen RBC units were collected from normal volunteers and stored under standard blood bank conditions; both metabolic changes and lipid parameters were measured by multiple novel assays including a new mass spectrometric measurement of isoprostane (lipid peroxidation) and flow cytometric assessment of CD47 expression. Band 3 oligomeric state was assessed by time-resolved phosphorescence anisotropy, and RBC morphology by microscopy of glutaraldehyde-fixed RBC. RESULTS Extracellular pH decreased and extracellular potassium increased rapidly during cold storage. Band 3 on the RBC membrane aggregated into large oligomers early in the storage period and coincident with changes in RBC morphology. Membrane lipid changes, including loss of unesterified cholesterol, lipid peroxidation and expression of CD47, also changed early during the storage period. In contrast loss of acetylcholinesterase activity and haemolysis of RBC occurred late during storage. DISCUSSION Our results demonstrate that changes in the macromolecular organisation of membrane proteins on the RBC occur early in storage and suggest that lipid peroxidation and/or oxidative damage to the membrane are responsible for irreversible morphological changes and loss of function during red cell storage.

Evaluation of Blood Storage Lesions in Leuko-depleted Red Blood Cell Units
Background: Red blood cells (RBCs) undergo biochemical and morphologic alterations during storage that are known as the storage lesions causing decreased RBC quality and are correlated with transfusion reactions in certain groups especially in infants and critically ill patients. Microvesicles (MVs) as one of storage lesions may be derived from various cell types and have key roles in several...
متن کاملRed blood cells storage lesion: the effect of blood donation time on biochemical parameters
Abstract Background and Objectives There is a circadian rhythm and diurnal variation in the redox capacity in blood plasma and there is a decrease in antioxidant capacity (TAC) during the RBCs storage in blood banking. So it is possible that donated blood, based on donation time, has a different antioxidant capacity and as a result a different biochemical response during storage. This study at...

Introduction: In present study, we evaluated the effect of plasma collected from packed red blood cells (PRBCs) at various weeks after donation on peripheral blood mononuclear cells (PBMCs). Methods: In this experimental study, plasma prepared from twenty PRBCs in the first, second, fourth, and fifth weeks after donation. PBMCs were also isolated from healthy donors and treated with different c...
متن کاملThe Frequency of Packed Red Blood Cells Transfusion in Preterm Infants Admitted to NICU of Shahid Sadoughi Hospital During 2016
Background: Red blood cells transfusion is a useful practice for preterm infants. Large amount of blood is usually wasted in the infants. Considering that few studies have been carried out on infants, the aim of current study was to investigate the frequency of packed red blood cells transfusion in preterm infants admitted to NICU of Shahid Sadoughi Hospital in Yazd during 2016 Materials and M...
متن کاملA Root Cause Analysis of Haemolysis Encountered in Leuco-filtration of Stored Packed Red Cells Units
Background and Aims: Leukoreduction of blood components has reduced the incidence of transfusion-associated adverse events. Leucofiltration is the most effective method of leukoreduction. We encountered haemolysis in a series of leucofiltered units. This stressed our precious inventory, added to financial loss, increased our turn-around time to issue leucofiltered blood units, and placed doubts...
