Abstract 115

Background: It has been suggested that inability to produce the anti-inflammatory cytokine IL-10 may predispose preterm infants to CLD1.

Aims: To measure IL-10 in bronchoalveolar lavage fluid from preterm infants.

Patients: 17 consecutive ventilated infants ≤ 29 weeks gestation on HFOV.

Measurements: Daily samples were analysed for IL-10 using an ELISA. CLD was defined as an oxygen requirement at 36 weeks corrected gestation.

Results: IL-10 was detectable at some point in all 17 infants. 9 of 11 survivors developed CLD. Their IL-10 (pg/ml) values are given below.Table

Conclusions: IL-10 is detectable in early bronchoalveolar lavage samples from ventilated preterm infants but does not prevent the development of CLD.
