Resumen

Introducción: en equipos con impedancia, la microcitosis y la poiquilocitosis presentan interferencia con el plaquetograma en anemias ferropénicas y talasemia, pero no se conoce en anemias secundarias o crónicas, lo que impide su correcta interpretación.

Objetivo: identificar las alteraciones eritroides en el extendido de sangre periférica (ESP) que interfieren con el plaquetograma, en pacientes con anemia microcítica heterogénea.

Metodología: a 50 pacientes hospitalizados con anemia microcítica heterogénea,
confirmada por el hemoleucograma y el ESP, se les analizó la morfología eritroide y plaquetaria.

Resultados: se encontró microcitosis de 1 a 2+, la correlación con el ancho de distribución plaquetaria y el volumen corpuscular medio fue significativa (p = 0,041 y p = 0,036, respectivamente), pero no se correlacionó con el P-LCR ni el conteo plaquetario. No hubo diferencia entre la morfología eritroide y el plaquetograma.

Conclusiones: la interpretación del plaquetograma por impedancia no está influenciada por la microcitosis y la poiquilocitosis en pacientes con anemia microcítica secundaria, debido a que dichas alteraciones son escasas. 

Keywords
