Abstract :Introduction: Most important factors in retinopathy of prematurity insert ignore into journalissuearticles values(ROP); are prematurity and oxygen toxicity although blood transfusions, insulin like growth factor-1 insert ignore into journalissuearticles values( IGF-1);, insulin like growth factor binding protein 3 insert ignore into journalissuearticles values(IGFBP-3); and vascular endothelial growth factor insert ignore into journalissuearticles values(VEGF); also have important roles. The objectives of this study were, to measure IGF-1 and IGFBP-3 levels in preterm newborns before and after blood transfusion and assess if the effect of transfusion in development of ROP is via these mediators, and to investigate whether IGF-1 and IGFBP-3 levels measured at 32 and 33 gestational age insert ignore into journalissuearticles values(GA); were different in preterm newborns with and without ROP. Material and Methods: Preterm newborns with gestational age ≤34 weeks were included and blood samples were obtained before and after red blood cell insert ignore into journalissuearticles values(RBC); transfusion. Results: Thirty newborns were included, 17 of whom had ROP insert ignore into journalissuearticles values( stage 1: n=11, stage 2: n=5, stage 3: n=1);. IGF-1 and IGFBP-3 levels did not change after RBC tranfusion. Excluding the patient with stage 3 ROP all ROP patients were referred as mild ROP. No difference was observed between IGF-1 and IGFBP-3 levels of the patients with and without mild ROP. Patients with mild ROP had significantly more number of transfusions. Conclusions: Erythrocyte transfusion increased the frequency of ROP, whereas IGFBP-3 and IGF-1 were not associated of ROP.
