Abstract Background Parechovirus-A3 (PeV-A3) is an emerging pathogen causing sepsis and meningoencephalitis in neonates and young infants. We previously reported that maternal antibodies against PeV-A3 are important to protect neonates and young infants from the infection. Recent studies showed that (1) breastfeeding had a protective effect against enterovirus, which is closely-related virus to PeV-A, and (2) human breast milk (HBM) neutralized enterovirus in vitro. Currently, no report is available related to the antiviral effect of HBM against PeV-A3. Methods HBM (colostrum, 3–5 days after childbirth; mature milk, 1 month after childbirth) and serum (within ± 1 week of child’s birthday) samples were obtained from mothers at obstetrics clinic in Niigata, Japan. Neutralizing antibody titers (NATs) against PeV-A3 were measured using the Vero cells. Results The anti-PeV-A3 NATs of colostrum (n = 32) ranged from 1:8 to 1:2048, those ≥1:32 was 59% (19/32). Whereas, the anti-PeV-A3 NATs of mature milk ranged from 1:8 to 1:96. and those ≥1:32 was 20% (2/20) (P < 0.001). The median NATs anti-PeV-A3 was higher in colostrum (1:32) compared with mature milk (1:8) (P < 0.001). There was a strong positive correlation between the NATs of colostrum and serum (r = 0.604, P < 0.001, Figure). Conclusion This study showed that HBM had high NATs against PeV-A3, which was correlated with serum NATs. Further studies are necessary to investigate which components of HBM has antiviral effects against PeV-A3. Disclosures All authors: No reported disclosures.

Safety And Efficacy

Human breast milk has been described as a source of lactic acid bacteria. Lactobacillus fermentum CECT5716 is a human breast milk strain whose probiotic properties, safety and efficacy has been demonstrated in vitro and in vivo, including controlled trials with human adults. Since the origin of this probiotic strain is human breast milk, we aimed to investigate the safety and efficacy of an infant and a follow-on formulas supplemented with this strain of L. fermentum. We carried out two randomised controlled trials: one trial with infants of 6-12 months of age (follow-on formula study) and another one with infants from 1 to 5 months of age (infant formula study). The results from the trials showed that the probiotic formulas were safe, well tolerated and might be useful for the prevention of community-acquired infections.

Background: Human breast milk provides a child with complete nutrition but is also a popular therapeutic remedy that has been used in traditional, natural pharmacopeia, and ethnomedicine for many years. The aim of this current review is to summarize studies of non-nutritional uses of mothers’ milk. Methods: Two databases (PubMed and Google Scholar) were searched with a combination of twelve search terms. We selected articles that were published between 1 January 2010, and 1 January 2019. The language of publication was limited to English. Results: Fifteen studies were included in the systematic review. Ten of these were randomized controlled trials, one was a quasi-experimental study, two were in vitro studies, and four employed an animal research model. Conclusions: Many human milk components have shown promise in preclinical studies and are undergoing active clinical evaluation. The protective and treatment role of fresh breast milk is particularly important in areas where mothers and infants do not have ready access to medicine.

Objective: This study was aimed to see the significance of Lactoferrin in human breast milk among lactating mothers of healthyand sick babies. Place and duration: This study was conducted at pathology and paediatrics departments of Peoples University of Medical andHealth Sciences Nawabshah, Shaheed Benazirabad between Jan 2011 to Dec 2011. Design: Cross sectional study. Method: Lactoferrinlevels in breast milk of 356 mothers of healthy babies were estimated and similarly lactoferrin levels in breast milk of 318 lactating mothers ofsick babies were estimated & these results were analyzed. Results: the mean lactoferrin level in breast milk of 356 lactating mothers of healthybabies was 9.37 mg/ml and the mean lactoferrin level in breast milk of 318 mothers nursing sick babies was 3.73mg/ml. Conclusions: There isdecrease in lactoferrin levels of lactating mothers of sick babies in their mature milk, which could account for the susceptibility of their babies toinfection.
