ABSTRACT

Determinar las concentraciones séricas de citocinas Th2 (IL4 e IL10), en niños desnutridos y eutróficos sin infección, en edades comprendidas entre 6 meses y 6 años. Se seleccionaron 89 niños; 64 niños con algún grado de desnutrición (leve, moderada y grave) y 25 niños eutróficos. Las citocinas se midieron en sangre periférica utilizando el método de ELISA doble sandwich. Para el análisis estadístico se utilizo el test de ANOVA con post test de Tukey. Se presentan como media + DE. La IL4 mostró en el grupo de desnutridos, niveles más elevados: leves (0.46 ± 0.04 pg/ml), moderados (0.48 ± 0.10 pg/ml) y graves (0.55 ± 0.006 pg/ml), presentando cada grupo diferencias significativas p < 0.001 en relación con el grupo control (0.37 ± 0.004 pg/ml). También hubo diferencias significativas entre los grupos de desnutridos leves y moderados con los graves p < 0.001. La IL10 mostró diferencias significativas entre los desnutridos moderados (9.91 ± 3.17 pg/ml) y graves (10.88 ± 5.13 pg/ml) con el grupo control (6.53 ± 2.59 pg/ml) p < 0.01. Los valores elevados de IL4 e IL10 en el niño desnutrido son consecuencia de un daño en la capacidad de activación de las células inmunitarias en los mismos, sumándose el grado de infestación parasitaria con helmintos que presentan, que condiciona la elevación de IL4.


To determine the cytokine serum measurements Th2 (IL4 and IL10), in malnourished children and eutrophic without infection, in ages understood between 6 months and 6 years. 89 children were selected; 64 children with some grade of malnourishment (mild, moderate and severe) and 25 eutrophic children. The cytokines was measured in outlying blood using ELISA'S double sandwich method. For the statistical analysis we use the test of ANOVA with post test of Tukey. They are presented like Mean + SD. The IL4 showed in the group of malnourished, higher levels: mild (0.46 ± 0.04 pg/ml), moderate (0.48 ± 0.10 pg/ml) and severe (0.55 ± 0.006 pg/ml), presenting each group significant differences (p < 0.001) in relation with the control group (0.37 ± 0.004 pg/ml). There were also significant differences among the groups of mild malnourished and moderate with the severe ones p < 0.001. The IL10 showed significant differences among the moderate malnourished (9.91 ± 3.17 pg/ml) and the severe (10.88 ± 5.13 pg/ml) with the control group (6.53 ± 2.59 pg/ml) (p < 0.01). The high values of IL4 and IL10 in the malnourished children are consequence of damage in the capacity of activation of the immune cells in the same ones, being added the grade of parasitic infection with worms that present that conditions the rise of IL4.
