          Abstract

          Como la anemia drepanocítica se caracteriza por una anemia hemolítica crónica, fue evaluada la fragilidad osmótica de eritrocitos normales y drepanocíticos. Se trabajó con sangre de individuos sanos y pacientes drepanocíticos. Se realizó la prueba de fragilidad osmótica inmediata. Los resultados muestran que la resistencia globular mínima fue al 0,45 % de NaCl y la resistencia globular máxima al 0,32 % de NaCl. En eritrocitos drepanocíticos la resistencia globular mínima fue al 0,36 % de NaCl y la resistencia globular máxima al 0,1 % de NaCl. Al comparar los resultados para cada tipo de célula se observó disminución de la fragilidad osmótica en eritrocitos drepanocíticos respecto a los normales, evidenciada por el desplazamiento de la curva hacia valores de NaCl inferiores. Se encontraron diferencias significativas entre las medias de los porcentajes de hemólisis en las soluciones entre 0,1 % y 0,36 % de NaCl (p < 0,05).

          Since sickle cell diseases are characterized by chronic hemolyticanemia, this work aims to characterize the osmotic fragility of normal and sickled erythrocytes. We worked with blood samples of healthy individuals and sickle cell patients. We carry out the rapid osmotic fragility test. The results show that the minimum globular resistance was at 0,45 % NaCl and the maximum resistance was at 0,32 % NaCl. In sickle cell, resistance was at 0,36 % NaCl and the maximum globular resistance was at 0,1 % NaCl. By comparing the results for each type of cell, we obtain decrease of osmotic fragility of the sickle cells against normal cells, showing a shift of the curve towards lower values of % NaCl. We found statistically significant differences between the means of the percentage of hemolysis in hypotonic solutions between 0,1 % and 0,36 % NaCl (p < 0,05).
