[Breast feeding of very preterm infants of HCMV-seropositive mothers]. / Muttermilchernährung der sehr unreifen Frühgeborenen von HCMV-seropositiven Müttern -- Stellungnahme.

ABSTRACT

Preterm infants can be infected with human cytomegalovirus (HCMV) transmitted via breast milk of their HCMV-seropositive mothers, 96 % of whom reactivate the virus during lactation. 38 % of exposed VLBW infants become infected, with 48 % of these developing at least one symptom. Whether priority should be given to the multiple advantages of breast milk feeding or to the avoidance of a possible HCMV infection by exclusive formula feeding still cannot be decided due to insufficient data on the long-term outcome of infected infants. Inactivation of HCMV in breast milk can be achieved safely only via heat treatment, but the clinical consequences resulting from the use of pasteurized breast milk are unknown. Given the above situation, the authors decided to continue breast-feeding of VLBW and ELBW infants in their units after obtaining informed parenteral consent, until data for an evidence-based decision become available.
