Systematic review links neutrophil extracellular trap dysregulation to pregnancy complications

A systematic review examined emerging evidence on the role of neutrophil extracellular trap (NET) dysregulation in pregnancy complications. The review focused on conditions including preeclampsia, gestational diabetes mellitus, preterm birth, recurrent pregnancy loss, systemic lupus erythematosus, and obstetric antiphospholipid syndrome. It proposed that excessive NET formation or defective clearance is strongly linked to the pathogenesis of these conditions, though the specific study designs, populations, and sample sizes of the included evidence were not reported.

The review also discussed the potential mechanistic roles of common obstetric medications—such as aspirin, metformin, low molecular weight heparin, hydroxychloroquine, and vitamin D—in relation to NET biology. No direct comparator groups, primary or secondary outcomes, or follow-up durations for the underlying studies were detailed. Consequently, no specific numerical results on efficacy or comparative effectiveness were presented.

Safety and tolerability data for the medications in this specific mechanistic context were not reported. Key limitations include the preliminary, narrative nature of the evidence, which is described as 'emerging.' The absence of reported study details, outcomes, and funding/conflict information restricts the ability to assess the strength of the associations. The practice relevance was not explicitly stated, and the review's findings should be interpreted as generating hypotheses for future research rather than providing direct clinical guidance.
