PURPOSE OF REVIEW: Pleural fibrosis is a double-edged sword in clinical settings. Successful induction of pleural fibrosis is the basis of therapeutic pleurodesis. On the other hand, pleural septations and fibrosis are undesirable outcomes in pleural infection and fibrothoraces. The significance of growth factors in the pathogenesis of pleural fibrosis has become increasingly apparent. RECENT FINDINGS: Recent findings have indicated that transforming growth factor beta is a key mediator of pleural fibrosis and demonstrated the therapeutic potential of both transforming growth factor beta itself and transforming growth factor beta inhibitors. Basic fibroblast growth factor has been highlighted as a key factor in successful pleurodesis, and in the formation of pleural effusions. Vascular endothelial growth factor inhibition has been shown to decrease pleural fibrosis in vivo. By contrast, hepatocyte growth factor stimulates non-fibrotic healing, while inhibition increases fibrosis. SUMMARY: The actions of the growth factors, and their inhibitors, are potentially and/or currently applicable in a clinical setting. Understanding the biology of these growth factors may allow therapeutic manipulation of these cytokines to create pleurodesis or to inhibit pleural (and peritoneal) adhesion/fibrosis.
OBJECTIVE: To determine if IGF-I, VEGF and bFGF, present in the serum of premature infants, are independent risk factors of the development of ROP. It was also our objective to design a multivariate model that included these three cytokines as indicator parameters in the ROP screening, in addition to the other parameters already in existence. METHODS: 74 patients were recruited with a birth weight below 1500g or gestational age below 32 weeks. These were classified into those who developed ROP (N = 37) and those without ROP (N = 37). We obtained serum from each infant at the time of the first examination at 4-6 postnatal weeks. These samples were frozen until the time of analysis. The roles of gestational age and birth weight were also evaluated. RESULTS: There were significant differences in the amount of the cytokines IGF-I and VEGF between the groups with or without ROP, but there were no significant differences for bFGF. The differences enabled us to establish a multivariate model including IGF-I and VEGF for the prediction of risk of ROP. CONCLUSIONS: Cytokine serum levels in premature infants can be useful as an indicator in ROP screening, as well as being used to predict the probability of suffering the illness.
