Correlation of augmented IL-8 production to premature chronic lung disease: implication of posttranscriptional regulation.

Despite that advances in neonatal medicine have significantly reduced the early mortality of premature infants, a considerable number of them are still prone to develop chronic lung disease (CLD) later. To find a method of early prevention, we investigated the efficacy of using certain early proinflammatory responses to predict the development of CLD. In the present study, 34 premature infants who required endotracheal intubation within 4 h of birth were recruited for analysis of IL-8, IL-10, and TNF-alpha levels in their bronchoalveolar lavage (BAL) fluid and blood.

Higher spontaneous and TNFalpha-induced apoptosis of neonatal blood granulocytes.

Granulocytes play an important role in inflammatory diseases. Neonates tend to develop granulocytopenia under sepsis and stress. It remains unclear whether apoptosis of neonatal granulocytes is different from that of adult granulocytes.
