<b><i>Objective:</i></b> This study aimed to assess reduced fetal growth between 35 weeks of gestation and birth in non-small for gestational age fetuses associated with adverse perinatal outcomes (APOs). <b><i>Material and Method:</i></b> It is a retrospective cohort study of 9,164 non-small for gestational age fetuses estimated by ultrasound at 35 weeks. The difference between the birth weight percentile and the estimated percentile weight (EPW) at 35 weeks of gestation was calculated, and we studied the relationship of this difference with the appearance of APO. APOs were defined as cesarean or instrumental delivery rates for nonreassuring fetal status, 5-min Apgar score &#x3c;7, arterial cord blood pH &#x3c;7.10, and stillbirth. Fetuses that exhibited a percentile decrease between both moments were classified into 6 categories according to the amount of percentile decrease (0.01–10.0, 10.01–20.0, 20.01–30.0, 30.01–40.0, 40.01–50.0, and &#x3e;50.0 percentiles). It was evaluated whether the appearance of APO was related to the amount of this percentile decrease. Relative risk (RR) was calculated in these subgroups to predict APOs in general and for each APO in particular. Receiver operating characteristic and area under curves (AUC) for the difference in the percentile was calculated, used as a continuous parameter in the entire study population. <b><i>Results:</i></b> The median gestational age at delivery in uncomplicated pregnancies was 40.0 (39.1–40.7) and in pregnancies with APOs 40.3 (49.4–41.0), <i>p</i> &#x3c; 0.001. The prevalence of APOs was greater in the group of fetuses with a decrease in percentile (7.6%) compared to those with increased percentile (4.8%) (<i>p</i> &#x3c; 0.001). The RR was 1.63 (95% CI: 1.365–1.944, <i>p</i> &#x3c; 0.001). Although the differences were significant in all decreased percentile groups, RRs were significantly higher when decreased growth values were &#x3e;40 points (RR: 2.036, 95% CI: 1.581–2.623, <i>p</i> &#x3c; 0.001). The estimated value of the AUC for percentile decrease was 0.58 (0.56–0.61, <i>p</i> &#x3c; 0.001). <b><i>Conclusion:</i></b> Fetuses with a decrease in the EPW between the ultrasound at 35 weeks of gestation and birth have a higher risk of APOs, being double in fetuses with a decrease of &#x3e;40 percentile points.

ABSTRACT Placenta-sequestering Plasmodium falciparum involved in the pathogenesis of pregnancy-associated malaria (PAM) in otherwise clinically immune women expresses particular variant surface antigens (VSAPAM) on the surface of infected erythrocytes that differ from VSA found in parasitized nonpregnant individuals (non-PAM type VSA). We studied levels of immunoglobulin G (IgG) and IgG subclasses with specificity for VSAPAM and for non-PAM type VSA in pregnant and nonpregnant women from two sites with different endemicities in Cameroon. We found that VSAPAM-specific responses depended on the pregnancy status, parity, gestational age, and parasite transmission intensity, whereas only the parasite transmission intensity influenced the levels of IgG specific for non-PAM type VSA. For both types of VSA, the responses were dominated by the cytophilic subclass IgG1, followed by IgG3. In pregnant women, the levels of VSAPAM-specific antibodies either were very low or negative or were very high, whereas the levels of the antibodies specific for non-PAM type VSA were uniformly high. Interestingly, the levels of VSAPAM-specific IgG1 increased with increasing gestational age, while the levels of the corresponding IgG3 tended to decrease with increasing gestational age. The IgG subclass responses with specificity for non-PAM type VSA did not vary significantly with gestational age. Taken together, our data indicate that IgG1 and to a lesser extent IgG3 are the main subclasses involved in acquired VSAPAM-specific immunity to pregnancy-associated malaria.
