Adequate Urinary Iodine Concentration among Infants in the Inland Area of Norway
2021
Considering the importance of iodine to support optimal growth and neurological development of the brain and central nervous system, this study aimed to assess and evaluate iodine status in Norwegian infants. We collected data on dietary intake of iodine, iodine knowledge in mothers, and assessed iodine concentration in mother’s breast milk and in infant’s urine in a cross-sectional study at two public healthcare clinics in the inland area of Norway. In the 130 mother–infant pairs, the estimated infant 24-h median iodine intake was 50 (IQR 31, 78) µg/day. The median infant urinary iodine concentration (UIC) was 146 (IQR 93, 250) µg/L and within the recommended median defined by the World He…
Current Insights on Early Life Nutrition and Prevention of Allergy
2020
The incidence of allergic diseases in childhood appears to have significantly increased over the last decades. Since environmental factors, including diet, have been thought to play a significant role in the development of these diseases, there is great interest in identifying prevention strategies related to early nutritional interventions. Breastfeeding is critical for the immune development of newborns and infants through immune-modulating properties and it impacts the establishment of a healthy gut microbiota. However, the evidence for a protective role of breastfeeding against the development of food allergy in childhood is controversial, and there is little evidence to support the ben…
Role of Vitamin A in Mammary Gland Development and Lactation
2019
Vitamin A (all-trans-retinol), its active derivatives retinal and retinoic acid, and their synthetic analogues constitute the group of retinoids. It is obtained from diet either as preformed vitamin A or as carotenoids. Retinal plays a biological role in vision, but most of the effects of vitamin A are exerted by retinoic acid, which binds to nuclear receptors and regulates gene transcription. Vitamin A deficiency is an important nutritional problem, particularly in the developing world. Retinol and carotenoids from diet during pregnancy and lactation influence their concentration in breast milk, which is important in the long term, not only for the offspring, but also for maternal health. …
Norovirus GII.4 antibodies in breast milk and serum samples: their role preventing virus-like particles binding to their receptors.
2014
Background: Norovirus GII.4 genotype is a leading cause of nonbacterial gastroenteritis in infants. Effective vaccines against noroviruses are not yet available, enhancing the interest of the protection mechanisms elicited by breast milk that may contain norovirus-specific antibodies and histo-blood group antigens. The aims of our study were to analyze norovirus GII.4-specific antibodies in breast milk and serum and to assess their blocking activity on recombinant norovirus virus-like particles (VLPs) binding to saliva. Methods: Mature milk and serum from 108 mothers were analyzed for specific IgA to norovirus GII.4-2006b and for their blocking activity on the binding of norovirus GII.4-200…
Transfer of aciclovir from plasma to human breast milk.
2011
Aciclovir (CAS 59277-89-3) is frequently used in herpes simplex virus diseases, but administration to lactating women occurs only rarely. Therefore, information about the pharmacokinetics of aciclovir in human breast milk is limited. The concentration in breast milk is 2 to 3 fold increased compared to plasma. The reason for this increase is unknown until now. An active transport mechanism has been assumed. The aim of this study was to prove whether the higher concentration of aciclovir in human breast milk is due to only a passive transfer. Two chambers separated by a semipermeable membrane were used. The first chamber contained plasma with aciclovir, the second chamber breast milk without…
Comparison of breast milk composition among lactating women in Latvia
2016
Abstract Although benefits of breast-feeding have been known for a long time and breast milk is considered as ideal nutrition for infants, the composition of breast milk is still being studied, since breast milk differs among mothers and populations, as well as during different times of lactation. Further, no study has been performed among lactating women in Latvia during recent years. The objective of the study was to determine the breast milk composition and influencing factors among lactating women in Latvia in different lactation periods, as well as to compare the results with data from other countries. Fifty breast milk samples were obtained from 44 mothers (on the 5th-7th and 11th-28t…

SARS-CoV-2 RNA and antibody detection in human milk from a prospective multicenter study in Spain
2021
Background During the COVID-19 pandemic in 2020, breastfeeding in women positive for SARS-CoV-2 was compromised due to contradictory data regarding potential viral transmission. However, growing evidence confirms the relevant role of breast milk in providing passive immunity by generating and transmitting specific antibodies against the virus. Thus, our study aimed to develop and validate a specific protocol to detect SARS-CoV-2 in breast milk matrix as well as to determine the impact of maternal SARS-CoV-2 infection on presence, concentration, and persistence of specific SARS-CoV-2 antibodies. Study design/Methods A prospective multicenter longitudinal study in Spain was carried out from A…

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
2022
Breast milk is a vehicle to transfer protective antibodies from the lactating mother to the neonate. After SARS-CoV-2 infection, virus-specific IgA and IgG have been identified in breast milk, however, there are limited data on the impact of different COVID-19 vaccine types in lactating women. This study is aimed to evaluate the time course of induction of SARS-CoV-2-specific IgA and IgG in breast milk after vaccination.
