The passage of orally fed proteins from mother to foetus in the rat

Materno–fetal passage of nutritive and inhalant allergens across placentas of term and pre‐term deliveries perfused in vitro

“…Although supplied allergen concentrations are relatively high and experiments performed with isolated placental tissue create an artificial situation, we observed transfer concentrations of the inhalant allergen Bet v1 comparable with recently published levels of house dust mite allergen measured in cord blood [16]. Similar transplacental transfer rates have been demonstrated in rats after feeding of dietary antigens [17].…”

"Tieguanyin Tea Like-Colored Amniotic Fluid Can be the Earliest Diagnostic Sign of Food Protein-Induced Enterocolitis Syndrome – 2 Case Reports"

“…The detection of allergen in the amniotic fluid and fetal blood has provided evidence of transplacental transfer [6,7], and there have been a few reported cases of FPIES sensitized in utero [3,8,9]. Ichimura et al reported a case that developed in utero with intestinal dilatation on fetal ultrasound but did not describe the amniotic fluid [3].…”

Case Reports of Cow's Milk Protein Allergy Presenting as Delayed Passage of Meconium With Early Onset Infant Constipation

“…This is well established. Research also suggests that cow's milk allergens can pass through the placenta and amniotic fluid (7) to sensitize fetuses (16,17), including fetal gut (16), at as early as 22 weeks of gestation (18) and cause CMPA. The latter includes conventional allergic colitis (19) and unconventional constipation (present study).…”
