Abstract

BACKGROUND: The contribution of local and systemic inflammation to the pathophysiology of sporadic first trimester miscarriages remains unclear. The objective of this study was to investigate the inflammatory response in the circulation of women presenting with first trimester miscarriage. METHODS: Levels of tumour necrosis factor alpha (TNFα), TNF receptors 1 and 2, interferon gamma (IFNγ), interleukin (IL)-6 and IL-10 were assayed using cytometric bead arrays in plasma samples from 29 euploid and 21 aneuploid missed miscarriages, 35 normal pregnant controls and 31 non-pregnant women (NPW). Whole blood flow cytometry was carried out with samples from 17 euploid and 16 aneuploid miscarriages, 18 pregnant controls and 13 NPW. RESULTS: The plasma of women with euploid miscarriage contained significantly higher circulating levels of TNFα (P < 0.005), IFNγ (P < 0.005), IL-6 (P < 0.005) and IL-10 (P < 0.01) than that of pregnant controls, irrespective of gestational age. Significantly (P < 0.05) higher TNF-R1 levels at 6-9 weeks, and significantly higher TNFα/IL-6 (P < 0.001) and significantly lower TNFα/IL-10 (P < 0.001) and IFNγ/IL-10 (P < 0.001) ratios at 10-14 weeks, were also found in euploid miscarriage cases compared with pregnant controls. TNFα/IL-10 ratio in plasma was significantly (P < 0.05) lower in miscarriages with an abnormal karyotype than those with normal karyotype. Normal pregnant women had a significantly higher plasma level of IFNγ (P < 0.01) and IFNγ/IL-10 ratio (P < 0.005), a significantly (P < 0.005) lower TNF-R1 level, and a significant (P < 0.05) increase in stimulated TNFα in monocytes, compared with NPW. CONCLUSIONS: Our data confirm that there is an inflammatory reaction in normal pregnancy compared with the non-pregnant state, which may be disrupted during miscarriage.

  • In pregnancy, synthesis of cytokines and growth factors is mildly increased while exhibiting Th1 helper cell dominance, but is further upregulated and changed to Th2 helper cell dominance during fetal distress, and decreases when resulting in premature birth.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
