“…However, cases of sensitisation of children under 5, even in high-risk areas or settings, are scarce in the literature. Although there is an established correlation between maternal and neonatal blood when it comes to passive transfer of anti-Anisakis IgG (5) , there have been no reports of anisakidosis in human pregnancy. Thus, the potential foetal effects of substances released by Anisakis spp.…”

“…The following parameters from each newborn were assessed: maternal age; histories of any prior pregnancy and the recent pregnancy; any birth events; vitality of the newborn at birth; and intake frequencies of fresh, frozen, raw, or slightly cooked fish. Information on blood collection from participants (5) , fish from which Anisakis specimens were collected and where they were purchased, identification of the nematode (Fisheries Laboratory at the Universidade Federal Fluminense School of Veterinary Medicine for taxonomic identification), larva and antigen handling (6) , and a detailed description of the ELISA protocol with cutoff ranges for the analysis of results is available elsewhere (7) . Binary categorical variables were used to indicate serum reactivity to anti-Anisakis spp.…”

Little is known about the influence of seroreactivity to fish nematode antigens on the unborn child. Aim: The objective of this study was to ascertain whether infants born to women with Anisakis spp. seroreactivity had problems with growth at birth, or during neonatal care. Methods: We conducted a retrospective database search of puerperal women interviewed at two perinatal facilities in Niterói, Brazil. Neonates were selected by the presence of anti-Anisakis IgG antibodies in cord blood and categorised, by analysis of maternal blood results, as reactive or nonreactive. The Mann-Whitney U test was used for hypothesis testing in continuous variables. A generalised linear model was used for binary logistic regression. Results: Of the 147 neonates studied, 121 were labelled as nonreactive and 26, as reactive. There were no significant betweengroup differences in maternal age (p = 0.193), number of prenatal visits (p = 0.362), presence of prenatal conditions (p = 0.980), mode of delivery (p = 0.193), gestational age (p = 0.266), birth weight (p = 0.294), need for resuscitation (p = 0.675), development of conditions during hospital stay (p = 0.201), or length of hospital stay (p = 0.528). There was also no significant association between IgG positivity in cord blood in raw fish intake (p = 1.000) or intake >2 times/week (p = 0.729). Conclusions: The presence of anti-Anisakis IgG in cord blood of infants born to women seroreactive to Anisakis did not pose a hazard to this neonatal population and did not influence growth, conditions at birth, or development of any clinical conditions before hospital discharge.
