SARS-CoV-2 RNA and antibody detection in breast milk from a prospective multicentre study in Spain
This study has been supported by a research grant from Fundacion La Marato-TV3 (MilkCORONA, ref 202106).Objectives To develop and validate a specific protocol
for SARS-CoV-
2 detection in breast milk matrix and to
determine the impact of maternal SARS-CoV-
2 infection
on the presence, concentration and persistence of
specific SARS-CoV-
2 antibodies.
Design and patients This is a prospective, multicentre
longitudinal study (April–December 2020) in 60 mothers
with SARS-CoV-
2 infection and/or who have recovered
from COVID-19. A control group of 13 women before the
pandemic were also included.
Setting Seven health centres from different provinces
in Spain.
Main outcome measures Presence of SARS-CoV-
2
RNA in breast milk, targeting the N1 region of the
nucleocapsid gene and the envelope (E) gene; presence
and levels of SARS-CoV-
2-specific
immunoglobulins
(Igs)—IgA, IgG and IgM—in breast milk samples from
patients with COVID-19.
Results All breast milk samples showed negative
results for presence of SARS-CoV-
2 RNA. We observed
high intraindividual and interindividual variability in
the antibody response to the receptor-binding
domain
of the SARS-CoV-
2 spike protein for each of the three
isotypes IgA, IgM and IgG. Main Protease (MPro)
domain antibodies were also detected in milk. 82.9%
(58 of 70) of milk samples were positive for at least

Metallomic and Untargeted Metabolomic Signatures of Human Milk from SARS-CoV-2 Positive Mothers
Scope
Lack of information about the impact of maternal severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on the elemental and metabolomic profile of human milk (HM).
Methods and results
An observational study on HM from mothers with COVID-19 is conducted including a prepandemic control group. Maternal–infant clinical records and symptomatology are recorded. The absolute quantification of elements and untargeted relative metabolomic profiles are determined by inductively coupled plasma mass spectrometry and gas chromatography coupled to mass spectrometry, respectively. Associations of HM SARS-CoV-2 antibodies with elemental and metabolomic profiles are studied. COVID-19 has a significant impact on HM composition. COVID-19 reduces the concentrations of Fe, Cu, Se, Ni, V, and Aluminium (Al) and increases Zn compared to prepandemic control samples. A total of 18 individual metabolites including amino acids, peptides, fatty acids and conjugates, purines and derivatives, alcohols, and polyols are significantly different in HM from SARS-CoV-2 positive mothers. Aminoacyl-tRNA biosynthesis, phenylalanine, tyrosine and tryptophan biosynthesis, phenylalanine, and linoleic acid pathways are significantly altered. Differences are obtained depending on COVID-19 symptomatic and asymptomatic status.
Conclusions
This study provides unique insights about the impact of maternal SARS-CoV-2 infection on the elemental and metabolomic profiles of HM that warrants further research due the potential implications for infant health.This work was supported by the projects PG2018-096608-B-C21(Spanish Ministry of Science and innovation (MCIN).

Increasing breast milk betaine modulates Akkermansia abundance in mammalian neonates and improves long-term metabolic health
Accelerated postnatal growth is a potentially modifiable risk factor for future obesity. To study how specific breast milk components contribute to early growth and obesity risk, we quantified one-carbon metabolism-related metabolites in human breast milk and found an inverse association between milk betaine content and infant growth. This association was replicated in an independent and geographically distinct cohort. To determine the potential role of milk betaine in modulating offspring obesity risk, we performed maternal betaine supplementation experiments in mice. Higher betaine intake during lactation increased milk betaine content in dams and led to lower adiposity and improved glucose homeostasis throughout adulthood in mouse offspring. These effects were accompanied by a transient increase in Akkermansia spp. abundance in the gut during early life and a long-lasting increase in intestinal goblet cell number. The link between breast milk betaine and Akkermansia abundance in the gut was also observed in humans, as infants exposed to higher milk betaine content during breastfeeding showed higher fecal Akkermansia muciniphila abundance. Furthermore, administration of A. muciniphila to mouse pups during the lactation period partially replicated the effects of maternal breast milk betaine, including increased intestinal goblet cell number, lower adiposity, and improved glucose homeostasis during adulthood. These data demonstrate a link between breast milk betaine content and long-term metabolic health of offspring.info:eu-repo/semantics/acceptedVersio
Breastfeeding during the COVID-19 pandemic: analysis of the breastmilk antibodies, neutralization capacity and microbiota profile from infected and vaccinated wome
Resumen del póster presentado a las III Jornadas Científicas PTI+ Salud Global, celebradas en el Centro de Ciencias Humanas y Sociales (CCHS), CSIC (Madrid) del 20 al 22 de noviembre de 2023.[Background] Breastmilk is considered the gold standard in infant nutrition and provides bioactive compounds to the neonate, among them antibodies and microbiota. In the context of the COVID- 19 pandemics, there were great concerns about a possible mother-to-infant transfer of SARS-CoV-2, since limited knowledge about the safety of breastfeeding after natural infection or vaccination, as well as the transfer of protective antibodies and their neutralization capacity, was available. Additionally, there are concerns about potential short- and long-term adverse effects of SARS-CoV-2 infection and vaccine-induced changes to the breastmilk microbiome composition, which contributes in shaping the early-life microbiome.[Methods] This study included 60 mothers which had a confirmed SARS-CoV-2 infection and also, 86 mothers vaccinated with mRNA-based (Comirnaty, mRNA-1273) and adenoviral-vectored vaccines (ChAdOx1 nCoV-19) were recruited and breastmilk samples were collected longitudinally from baseline up to 30 days after the second dose at seven or eight time points (depending on vaccine type). In COVID-19 lactating mothers, the presence of SARS-CoV-2 was assessed by RT-qPCR targeting the N1 region of the nucleocapsid gene and the envelope (E) gene. In both studies, the levels of SARS-CoV-2 RBD-specific IgA, IgM and IgG were determined by ELISA. The neutralization capacity was tested using pseudotyped vesicular stomatitis virus carrying either the Wuhan-Hu-1, Delta, or BA.1 Omicron spike proteins. To assess the microbiome composition, DNA from breastmilk samples was extracted and the V3-V4 region of the 16S rRNA gene was sequenced using the MiSeq system of Illumina.[Results] After SARS-CoV-2 infection, no virus-specific RNA was detected in breastmilk samples. Determination
of antibody levels in mothers with confirmed SARS-CoV-2 infection showed that 82.9% (58 of 70) of milk samples were positive for at least one of the three tested antibody isotypes. Vaccination elicited also a strong induction of SARS-CoV-2-specific antibodies, which was higher in IgG when compared to COVID-19 convalescent women and was strongly increased after the 2nd dose. mRNA-based vaccines induced higher IgG and IgA levels when compared to the adenovirus- vectored vaccine, and women with previous virus exposure increased their IgG antibodies levels after the first dose to a similar level observed in vaccinated women after the second dose. When assessing the neutralization capacity, natural infection resulted in higher neutralizing titers that correlated positively with levels of SARS-CoV-2-specific immunoglobulin A in breastmilk. Breastmilk samples from COVID-19 convalescent mothers infected during the first wave (Wuhan-Hu-1 strain) neutralized less effectively Omicron BA.1 than the Wuhan-Hu-1 variant. In addition, significant differences in the capacity to produce neutralizing antibodies were observed between both mRNA- based vaccines and the adenovirus-vectored ChAdOx1 COVID-19 vaccine. First results of the analysis of the breastmilk microbiome found no significant differences in the mean diversity of species (alpha-diversity) after natural SARS-CoV-2 infection, whereas some specific bacterial groups were increased (e.g. Enterobacteriaceae).[Conclusions] Overall, our results indicate that breastmilk from naturally infected women or those vaccinated with
mRNA-based vaccines contain SARS-CoV-2 neutralizing antibodies that could potentially provide protection to breastfed infants from infection.Peer reviewe

Seguimiento de las guías españolas para el manejo del asma por el médico de atención primaria: un estudio observacional ambispectivo
Objetivo
Evaluar el grado de seguimiento de las recomendaciones de las versiones de la Guía española para el manejo del asma (GEMA 2009 y 2015) y su repercusión en el control de la enfermedad.
Material y métodos
Estudio observacional y ambispectivo realizado entre septiembre del 2015 y abril del 2016, en el que participaron 314 médicos de atención primaria y 2.864 pacientes.
Resultados
Utilizando datos retrospectivos, 81 de los 314 médicos (25, 8% [IC del 95%, 21, 3 a 30, 9]) comunicaron seguir las recomendaciones de la GEMA 2009. Al inicio del estudio, 88 de los 314 médicos (28, 0% [IC del 95%, 23, 4 a 33, 2]) seguían las recomendaciones de la GEMA 2015. El tener un asma mal controlada (OR 0, 19, IC del 95%, 0, 13 a 0, 28) y presentar un asma persistente grave al inicio del estudio (OR 0, 20, IC del 95%, 0, 12 a 0, 34) se asociaron negativamente con tener un asma bien controlada al final del seguimiento. Por el contrario, el seguimiento de las recomendaciones de la GEMA 2015 se asoció de manera positiva con una mayor posibilidad de que el paciente tuviera un asma bien controlada al final del periodo de seguimiento (OR 1, 70, IC del 95%, 1, 40 a 2, 06).
Conclusiones
El escaso seguimiento de las guías clínicas para el manejo del asma constituye un problema común entre los médicos de atención primaria. Un seguimiento de estas guías se asocia con un control mejor del asma. Existe la necesidad de actuaciones que puedan mejorar el seguimiento por parte de los médicos de atención primaria de las guías para el manejo del asma.
Objective: To assess the degree of compliance with the recommendations of the 2009 and 2015 versions of the Spanish guidelines for managing asthma (Guía Española para el Manejo del Asma [GEMA]) and the effect of this compliance on controlling the disease.
Material and methods: We conducted an observational ambispective study between September 2015 and April 2016 in which 314 primary care physicians and 2864 patients participated.
Results: Using retrospective data, we found that 81 of the 314 physicians (25.8%; 95% CI 21.3–30.9) stated that they complied with the GEMA2009 recommendations. At the start of the study, 88 of the 314 physicians (28.0%; 95% CI 23.4–33.2) complied with the GEMA2015 recommendations. Poorly controlled asthma (OR, 0.19; 95% CI 0.13–0.28) and persistent severe asthma at the start of the study (OR, 0.20; 95% CI 0.12–0.34) were negatively associated with having well-controlled asthma by the end of the follow-up. In contrast, compliance with the GEMA2015 recommendations was positively associated with a greater likelihood that the patient would have well-controlled asthma by the end of the follow-up (OR, 1.70; 95% CI 1.40–2.06).
Conclusions: Low compliance with the clinical guidelines for managing asthma is a common problem among primary care physicians. Compliance with these guidelines is associated with better asthma control. Actions need to be taken to improve primary care physician compliance with the asthma management guidelines
Persistence of Anti SARS-CoV-2 Antibodies in Breast Milk from Infected and Vaccinated Women after In Vitro-Simulated Gastrointestinal Digestion
Breastfeeding is key for infant development and growth. Breast milk contains different bioactive compounds including antibodies. Recent studies have demonstrated the presence of breast milk SARS-CoV-2 antibodies after maternal infection and vaccination. However, the potential impact on the infant has not been explored yet. As a first step, we aimed at assessing the potential persistence of SARS-CoV-2 IgA and IgG antibodies from infected and vaccinated women in the gastrointestinal tract of the infants by means of an in vitro-simulated gastrointestinal digestion approach. Breast milk samples from 10 lactating women receiving mRNA vaccination against SARS-CoV-2 (n = 5 with BNT162b2 mRNA and n = 5 with mRNA-1273) and also, COVID-19 infected (n = 5) were included. A control group with women with no exposure to the virus (n = 10 pre-pandemic) were also studied. The presence of IgA and IgG SARS-CoV-2 antibody levels was determined by ELISA after the gastric and intestinal stages. The impact of digested antibodies on infant gut microbiota was tested by simulating colonic fermentation with two different fecal inoculums: infants from vaccinated and non-vaccinated mothers. Specific gut microbial groups were tested by targeted qPCR. In vitro infant gastrointestinal digestion significantly decreased the levels of both anti-SARS-CoV-2 IgA and IgG. However, both remained resistant in all the study groups except in that evaluating breast milk samples from infected women, in which IgG was degraded below the cut-off values in the intestinal phase. No effect of the antibodies on microbiota were identified after digestion. In conclusion, antibody levels against SARS-CoV-2 are reduced after in vitro-simulated gastrointestinal tract but remain present, so a positive biological effect could be expected from this infant immunization pathway.This work was supported by the research grant from LaMarató-TV3 (MilkCORONA, No. 31/109/202106).

Anti-Sars-Cov-2 IgA And IgG In Human Milk After Vaccination Is Dependent On Vaccine Type And Previous Sars-Cov-2 Exposure: A Longitudinal Study
Importance Limited data are available on COVID-19 vaccine impact in lactating women.
Objective To evaluate the impact of different COVID-19 vaccines on specific anti-SARS-CoV-2 IgA and IgG levels in human milk.
Design, Settings and Participants In this prospective observational study in Spain, 75 lactating women from priority groups receiving vaccination against SARS-CoV-2 were included (January to April 2021). Human milk samples were collected at seven-time points. A group with confirmed SARS-CoV-2 infection (n=19) and a group of women from prepandemic time (n=13) were included.
Exposure mRNA vaccines (BNT162b2 and mRNA-1273) and adenovirus-vectored vaccine (ChAdOx1 nCoV-19).
Main Outcome(s) and Measure(s) Presence of IgA and IgG against RBD SARS-CoV-2 in breast milk.
Results Seventy-five vaccinated lactating women [mean age, 34.9 ± 3.7 years] of whom 96% were Caucasic and 92% were health care workers. A total of 417 milk samples were included and vaccine distribution was BioNTech/Pfizer (BNT162b2, n=30), Moderna (mRNA-1273, n=21), and AstraZeneca (ChAdOx1 nCoV-19, n=24). For each vaccine, 7 time points were collected from baseline up to 25 days after the 1st dose and same points were collected for mRNA vaccines 30 days after 2nd dose. A strong reactivity was observed for IgG and IgA after vaccination mainly after the 2nd dose. Presence and the persistence of specific SARS-CoV-2 antibodies in breast milk were dependent on the vaccine-type and, on previous virus exposure. High inter-variability was observed, being relevant for IgA antibodies. IgG levels were significantly higher than those observed in milk from COVID-19 women while IgA levels were lower. Women with previous COVID-19 increased the IgG levels after the 1st dose to a similar level observed in vaccinated women after the 2nd dose.
Conclusions and Relevance Breast milk from vaccinated women contains anti-SARS-CoV-2 IgA and IgG, with highest after the 2nd dose. Levels were dependent on vaccine type and previous exposure to SARS-CoV-2. Previous COVID-19 influenced the vaccine effect after a single dose, which could be especially relevant in the design of vaccination protocols. Further studies are warranted to demonstrate the potential protective role of these antibodies against COVID-19 in infants from vaccinated and infected mothers through breastfeeding.Peer reviewe
