Intrauterine viral infection at the time of second trimester genetic amniocentesis

Wenstrom, K·1998·Obstetrics & Gynecology

Abstract

OBJECTIVE: To determine whether preexisting intrauterine viral infection is associated with postamniocentesis pregnancy loss. METHODS: We accessed our bank of second-trimester amniotic fluid (AF) samples obtained aseptically and stored at -20C from all 11,971 women who underwent genetic amniocentesis between 1988 and 1995. Samples were retrieved from every case of spontaneous pregnancy loss within 30 days of the amniocentesis (excluding aneuploidy and anomalies, n = 66). Sixty-six control samples were randomly chosen from subjects who delivered at term and were matched for year of test, gestational age, maternal age, and indication for amniocentesis. Investigators were blinded to the status of the samples, which were studied by polymerase chain reaction (PCR) for the presence of adenovirus, parvovirus, cytomegalovirus, Epstein-Barr virus, herpes simplex virus, enterovirus, influenza A virus, and beta-actin DNA. Results were compared with interleukin-6 (IL-6) levels previously measured by enzyme-linked immunosorbent assay in the same samples. RESULTS: Sixty-two study cases and 60 controls were sufficient for all PCR studies. Fourteen AF samples contained a single virus: five (8%) of 62 study cases and nine (15%) of 60 controls (P = .27). Adenovirus accounted for nine (64%) of 14 viruses identified: four of 62 cases and five of 60 controls (P = .74). Cytomegalovirus was not identified in any study cases but was found in three controls. The mean IL-6 levels in samples with and without virus were not significantly different (4.8+/-15.9 ng/mL with virus compared with 2.0+/-8.8 ng/mL without virus; P = .53). CONCLUSION: Presence of virus in second-trimester AF is not significantly associated with elevated IL-6 levels or with early postamniocentesis pregnancy loss.

  • Viral DNAs in the amniotic fluid of asymptomatic women undergoing genetic amniocentesis were generally unrelated to subsequent preterm births, so it seems unlikely that maternal viral infection plays an important part in preterm birth.

    “In several studies, the viral DNAs—identified by PCR techniques—in the amniotic fluid of asymptomatic women undergoing genetic amniocentesis were generally unrelated to subsequent preterm births;115 therefore, it seems unlikely that maternal viral infection plays an important part in preterm birth, but controversy persists, and with little information, further study is needed.116”

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.
