Respiratory Infections
Conditions
Brief summary
Acute respiratory infections are the leading cause of hospitalization in premature infants worldwide. Severity rates are particularly high in developing countries. Numerous viruses can cause severe disease, but the most frequent agent of hospitalization is respiratory syncytial virus (RSV). In a recent study in Argentina, 58% of RSV infected VLBW infants required hospitalization and 19% required mechanical ventilation. One every twenty infected infants died. Unlike industrialized nations, VLBW infants in developing countries often lack access to prophylaxis against RSV with a commercially available monoclonal antibody (palivizumab). No vaccine or preventive intervention is available against any respiratory virus for infants younger than 6 months of age in developing countries and the public sector of most middle-income countries. The protective role of breastfeeding against respiratory infections in developing countries is well established. But while similar beneficial effects have been described for premature infants, the dropout rate for breastfeeding in families exposed to the uncertainties and stress of the early months of life in the neonatal intensive care unit is very high. The World Health Organization recommends the use of Human Milk Donor Banks to feed infants that cannot be breastfed by their own mothers. These banks are established with the purpose of collecting, screening, processing (including pasteurizing), testing and distributing donated human milk. The potential benefit of donated milk against acute disease elicited by RSV is unknown. The investigators propose to study the role of supplemental donated human milk in the prevention of hospitalizations caused by RSV in non-breastfeeding premature infants. Since the investigators expect the benefits of breast milk to extend beyond protection against RSV, the effect of human milk against respiratory infections elicited by other viruses will also be evaluated.

Inclusion criteria
* VLBW preterm neonates (birth weight \<1,500 g at birth; gestational age \<37 weeks) born alive at any of the two participating maternity hospitals integrating our network in Argentina will be enrolled in the study after signature of informed consent.
Exclusion criteria
* VLBW infants older than one month of age (e.g.: transferred from another institution), or formula fed for over ten days, or with congenital heart disease, congenital anomalies of the respiratory tract (i.e.: tracheoesophageal fistula, pulmonary hypoplasia, diaphragmatic hernia), immune suppression, severe malformations affecting breathing (i.e. anencephaly) as well as infants who die prior to completion of the first questionnaire, or living more than 40 km away from the Hospital will be excluded from participation. Infants born from human immunodeficiency virus (HIV) positive mothers will also be excluded
