For Bone Marrow - donors willing to donate BM and who wish to resume breastfeeding post donation, should wait for at least 24 hours after the last dose of anaesthetic was administered, to avoid transfer it to the baby (general anaesthesia may cause severe events in the baby).

For PBSC - donors willing to donate PBSC should stop breastfeeding prior to the first dose of G-CSF and resume it at least 48 hours after the last dose has been administered, also to avoid contact of the baby with G-CSF. The safety profile of G-CSF has not been tested during pregnancy thus the it is unknown whether baby is at risk of adverse events.

Acceptability at Recruitment

ACCEPTABLE

Acceptability at CT / Work-Up

QUALIFIED if the donor is sufficiently informed about and accepts the fact that there are limited data on safety or is willing to interrupt breastfeeding (and throw away any expressed milk, “pump and dump”) during mobilization and for three days after PBSC and for at least 24 hours after Bone Marrow Collection (discuss case per case with the attending anesthesiologist).

Explanation of Condition

Justification for Guidance

We generally recommend that breast-feeding mothers do not donate and, regardless of breast-feeding, donation is not permitted within six months of a term pregnancy.

However, many breast-feeding donors who are more than six months following delivery feel very strongly that they would like to donate, and would be prepared to stop or suspend breast-feeding at the time of donation.


PBSC harvest

Breast-feeding donors may donate by PBSC if they are prepared to stop breast-feeding on commencing G-CSF injections and to abstain for three days following their donation. It is safe for the mother to express before this three-day period has expired, but the expressed milk should be discarded.

In donors who breastfeed and are qualified to donate (taking the recovery period after pregnancy into consideration) the concern is that drugs used in the donation procedure may be ingested by and harmful for the infant. In line with this, several donor suitability guidance documents consider uninterruptible breastfeeding a contra-indication for PBSC and ask the donor if she is willing to interrupt breastfeeding during mobilization and for a couple of days after donation. However, G-CSF is a normal component of breast milk. Limited research shows that filgrastim and lenograstim are poorly excreted into breastmilk and are undetectable by 3 days after an injection. Evidence also suggests that G-CSF given to neonates orally is not absorbed in significant quantities. In a single-center crossover study in which 22 infants received 1 dose of rhG-CSF (100 microg/kg) (10 times the subcutaneous dose) orally, no side-effects, safety issues or significant changes in plasma G-CSF concentration were observed. In a placebo controlled study G-CSF was safely given to 8 infants suffering from necrotizing enterocolitis. These studies suggest that G-CSF mainly has a local effect on the GI tract and not systemically.


Bone marrow harvest

Anaesthetic drugs are generally very short-lived in the maternal blood stream. Breast-feeding may continue up until anaesthetic induction prior to the bone marrow harvest, and mothers may recommence feeding 24 hours following recovery from anaesthetic, i.e after 'waking up'. If any other medications are given around the time of the procedure, such as sedating benzodiazepines (e.g. midazolam/diazepam), or opiates (e.g. morphine/codeine) then advice should be sought from the attending anaesthetist.
