Descriptor English: Erythrocyte Aggregation
Descriptor Spanish: Agregación Eritrocitaria
Descriptor agregación eritrocítica
Entry term(s) agregación eritrocitaria
agregación eritrocítica intravascular
Scope note: Formación de agregados de ERITROCITOS en condiciones de flujo escaso o nulo, como consecuencia de las fuerzas de atracción entre las células sanguíneas de la serie roja. Las células se adhieren entre sí formando agregados apilados. Cualquier fuerza mecánica ligera, como es la circulación, puede dispersar estos agregados. La agregación puede ser más o menos fuerte dependiendo de muy diversos efectos en la MEMBRANA ERITROCÍTICA o en el PLASMA SANGUÍNEO. El grado de agregación se ve afectado por la DEFORMABILIDAD DEL ERITROCITO, la sialilación de la membrana eritrocítica, el enmascaramiento de la carga negativa de superficie por las proteínas del plasma, etc. La VISCOSIDAD SANGUÍNEA y la VELOCIDAD DE SEDIMENTACIÓN GLOBULAR se ven afectadas por la cantidad de agregación eritrocitaria, y existen parámetros para medir dicha agregación.

Scope note: The formation of clumps of RED BLOOD CELLS under low or non-flow conditions, resulting from the attraction forces between the red blood cells. The cells adhere to each other in rouleaux aggregates. Slight mechanical force, such as occurs in the circulation, is enough to disperse these aggregates. Stronger or weaker than normal aggregation may result from a variety of effects in the ERYTHROCYTE MEMBRANE or in BLOOD PLASMA. The degree of aggregation is affected by ERYTHROCYTE DEFORMABILITY, erythrocyte membrane sialylation, masking of negative surface charge by plasma proteins, etc. BLOOD VISCOSITY and the ERYTHROCYTE SEDIMENTATION RATE are affected by the amount of erythrocyte aggregation and are parameters used to measure the aggregation.
