Placental antibody transfer: influence of maternal HIV infection and placental malaria
Open accessAbstract
AIM: To determine the influence of placental malaria, maternal HIV infection, and maternal hypergammaglobulinaemia on transplacental IgG antibody transfer. METHODS: One hundred and eighty materno-neonatal pairs from a Malawian population were assessed. Cord and maternal serum samples were tested for total serum IgG antibody titres using nephelometry, and for specific IgG antibody titres to Streptococcus pneumoniae, measles, and tetanus toxoid antibodies using an enzyme linked immunsorbent assay (ELISA). RESULTS: Multiple regression analyses showed that placental malaria was associated with a decrease in placental IgG antibody transfer to S pneumoniae and measles to 82% and 81%, respectively. Maternal HIV infection was associated with a reduction in IgG antibody transfer to S pneumoniae to 79%; raised maternal total serum IgG titres were correlated with S pneumoniae and measles IgG antibody transfer reduction to 86% and 87%, respectively. No effect was seen with tetanus toxoid antibody transfer. CONCLUSION: The combined influence of placental malaria, maternal HIV infection, and maternal hypergammaglobulinaemia seems to be linked to the low transplacental antibody transfer observed in the Malawian population.

Calculations based on data from 9 African studies found that mothers averaged 17.3 ± 3.1 mg/ml IgG, cord blood 14.7 ± 2.5 mg/ml, with CMR of 0.85 ± 0.15.
“In comparison, calculations based on data from 9 African studies for mothers averaged 17.3 ± 3.1 mg/IgG, cord blood 14.7 ± 2.5 mg/ml, with CMR of 0.85 ± 0.15,13,14,16,30–34.”

The Results (Table 2; page not available in our copy) report maternal and cord IgG measurements from this Malawian study, including 17.3 g/L for HIV-seronegative mothers. The paper does not report calculations across nine African studies or the quoted aggregate cord value, variability, and CMR, so it supports the underlying study-data citation but not those summary figures.

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.
