Clinical Trial Summary

The goal of this observational study is to determine the concentration of medicines in human milk during maternal medicine intake. The main questions it aims to answer are: - What is the concentration of maternal medicines in human milk? - What is the (estimated) intake and exposure in the breastfed infant? Participants will be asked to - fill out a questionnaire regarding medical data of the mother and child - track medication intake for 3 days - collect milk samples during 24 hours - optionally, donate 2 blood samples of the mother and give consent to one blood sample of the child - fill out a questionnaire regarding the general health of the child.


Description:

There is an immense information gap regarding safety of medicines during lactation which can result in a lack of breastfeeding adherence. According to literature, 50% of women need pharmacotherapy in the postpartum period. However, the proportion of nursing women in need of medication rises, due to later age pregnancies and the increased prevalence of chronic diseases. Evidence-based decisions on the use and selection of medicine during breastfeeding are challenging for many medicines, due to the lack of available information, such as cardiovascular compounds (e.g. atorvastatin, simvastatin), antidepressants (e.g. venlafaxine), anti-epileptics (e.g. topiramate, pregabalin), etc. This often results in unnecessary cessation of breastfeeding or poor adherence to/avoidance of pharmacological treatment. The objective of this prospective trial is to collect information about the human milk transfer of maternal medicines, subsequent infant exposure, and general health outcome of the infant. Furthermore, the data of this clinical lactation study will be used to verify the performance of pharmacologically-based pharmacokinetic (PBPK) models to predict disposition of medicines in human milk and subsequent neonatal exposure during lactation. An umbrella protocol approach is used. This means that each request or compound for which milk samples might be collected / offered by women, will be reviewed and evaluated for feasibility and relevance. The investigators expect to enroll 5, at maximum 15, mothers per year, who have been prescribed maternal medication for medical reasons and are breastfeeding their infant (/expressing milk) while taking this medication. The participating mother will be asked to collect milk samples and optionally to donate 2 blood samples during 24h: one at the time of milk pumping the first time after medication intake and one at the last pumping session of the 24h period. The parents can optionally consent for collecting a blood sample of the infant for the study (1-5% of the total blood volume, according to the FDA guidelines). In addition, clinical maternal and infant variables will be collected, as well as medication regimen, sampling details and general infant health information using 2 questionnaires. To conclude, with this study data about the concentration of maternal medication in human milk, and the exposure in the nursing infant will be generated. This information is an essential first step towards evidence-based risk assessment on the use of drugs during lactation.

Intervention

Other:
Human milk collection
Every time the mother would normally feed the child, we ask to collect the total milk volume for the feed from both breasts by an electric pump. For each collection, the volume and time will be noted, the container will be inverted and 5 to 10ml of that volume will be transferred in a polypropylene test tube or other tube type depending on the type of compounds (=sample to determine drug concentration in milk) for analysis (max 10% of the collected volume of each feed). The participant decides how the remainder of the collected milk is used. The milk samples will immediately be stored in the refrigerator (4°C) after being labeled. The samples will be collected by one of the investigators within 24 hours, will be transported on ice and frozen at -80°C until analysis.
Optionally: maternal blood sample
Blood collection to determine the drug concentration in plasma (6 to 10mL EDTA or other tube type, depending on the type of compound) will be performed at least within 1 hour interval with the first feeding (pumping) after medication intake, and 24 hours after medication intake (with preferable milk collection within 1 hour of blood sampling). The sample label, date and time of sampling will be noted.
Optionally: child blood sample
Blood collection of the infant to determine systemic exposure of child(1-5% of the total blood volume, according to the FDA guidelines, in an EDTA or other tube type, depending on the type of compound,) will be performed at the same day as the maternal sampling, if parental consent is obtained. The sample label, date and time of sampling will be noted.
