Abstract

OBJECTIVE:

During pregnancy cytokines and inflammatory mediators stimulate the expression of prostaglandin, the levels of which determine the onset of labor. The aim of this work was to study interleukin IL-1beta, IL-6 and IL-8 levels in the vaginal discharge, serum and urine of pregnant women with genitourinary infection before and after specific treatment. One hundred and fifty-one patients were studied during the second or third trimester of their pregnancy.

METHODS:

The selected patients were: healthy or control group (n = 52), those with bacterial vaginosis (n = 47), those with vaginitis (n = 37), those with asymptomatic urinary infection (n = 15) and post-treatment. The level of cytokines was assayed by ELISA test. The Mann-Whitney U-test was used for statistical analysis.

RESULTS:

The IL-1beta levels in vaginal discharge were: control 103.5 +/- 24.2 pg/ml, bacterial vaginosis 1030 +/- 59.5, vaginitis 749.14 +/- 66.7l ( p < 0.0001), post-treatment 101.4 +/- 28.7. IL-6 values were similar in both control and infected groups, and there were no patients with chorioamnionitis. In vaginal discharge IL-6: control 14.2 +/- 3.9 pg/ml, bacterial vaginosis 13.2 +/- 3.8, vaginitis 13 +/- 4.2. IL-8 levels were: control 1643 +/- 130.3 pg/ml, bacterial vaginosis 2612.7 +/- 257.7, vaginitis 3437 +/- 460 (p < 0.0001), post-treatment 1693 +/- 126.6. In urine the results were: control 40.2 +/- 17 pg/ml, asymptomatic urinary infection 1200.7 +/- 375 (p < 0.0001). In patients with therapeutic success both IL-1beta and IL-8 returned to normal levels.

CONCLUSIONS:

Genitourinary infections induce a significant increase in IL-1beta and IL-8 levels in vaginal secretions, and IL-8 in urine as well. Both cytokines could be useful as evolutive markers of infection.
