Concentraciones de interleucina-18 en preeclámpticas y embarazadas normotensas sanas

Objective

To compare concentrations of interleukin-18 in pre-eclampsia patients and healthy normotensive pregnant women.

Method

A total of 100 patients were selected. Fifty pre-eclamptic patients were selected as cases (group A) and a control group selected by having the same age and body mass index to study group, consisting of 50 healthy normotensive pregnant women. Blood samples were collected in all patients before labour and immediately after diagnosis in group B to determine interleukin-18 concentrations.

Results

There were no significant differences in relation to maternal age, gestation age and body mass index at the time of taking the sample (P = ns). There was a statistically significant difference in interleukin-18 concentrations between patients in cases group (group A; 38.6 ± 6.5 pg/ml) and patients in control group (group B; 32.2 ± 8.5 pg/ml; P < .05). There was a moderate, positive and significant correlation with systolic blood pressure values (r = 0.341; P < .05) and with diastolic blood pressure values (r = 0.408; P < .05).

Conclusions

Pre-eclampsia patients had significantly higher concentrations of interleukin-18 when compared with healthy normotensive pregnant women.
