Cytokines, Pregnancy, and Bacterial Vaginosis: Comparison of Levels of Cervical Cytokines in Pregnant and Nonpregnant Women with Bacterial Vaginosis
Bibliographic record
Abstract
BACKGROUND: Pregnancy has been considered to be a time of relative immune compromise. Lower-genital-tract immune response appears to be influenced by pregnancy. The objective of this study was to compare, in pregnant versus nonpregnant women, endocervical proinflammatory-cytokine expression in response to bacterial vaginosis. METHODS: Endocervical levels of interleukin (IL)-1 beta , IL-6, and IL-8 in 99 pregnant and 99 nonpregnant women, all with bacterial vaginosis and without concurrent sexually transmitted infections, were assessed by ELISA. Vaginal flora was characterized on the basis of quantitative vaginal cultures. RESULTS: Women in the 2 groups differed with respect to smoking status and microbiological constituents responsible for bacterial vaginosis. When the data were stratified by these potential confounders, the levels of all 3 proinflammatory endocervical cytokines were significantly higher in pregnant women than in nonpregnant women. CONCLUSIONS: The proinflammatory cytokine milieu in the cervix is enhanced in pregnant women with bacterial vaginosis, compared with that in nonpregnant women. The notion of pregnancy as an immune-compromised state may be anatomically compartment specific.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
