Haemozoin as a marker of placental parasitization
Abstract
Both Plasmodium vivax and P. falciparum malaria can cause the delivery of low birthweight babies. In this report, we have quantitated haemozoin levels in placentas from women living on the Thai-Burmese border in a region of low transmission for both P. falciparum and P. vivax malaria from June 1995 to January 2000. P. falciparum malaria infections during pregnancy lead to the accumulation of haemozoin (malaria pigment) in the placenta, especially in infections near term and in primigravid pregnancies. Haemozoin concentration was not associated with adverse birth outcomes. Women with P. vivax infections during pregnancy do not have measurable levels of placental haemozoin suggesting that P. vivax-infected erythrocytes do not accumulate in the placenta as much as P. falciparum-infected ones.

Hemozoin can persist for months following treatment of a documented infection, and the extent of hemozoin deposition is thought to correlate with cumulative exposure, with levels associated with gravidity, degree of parasitemia at treatment and reinfection before delivery.
“Hemozoin can persist for months in women following treatment of a documented infection [58], and the extent of hemozoin deposition is thought to correlate with cumulative exposure [54] such that levels have been associated with gravidity, the degree of parasitemia at the time of treatment and reinfection before delivery [57].”

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.
