Abstract

Background: Small for gestational age (SGA) infants have an increased risk of later cardiovascular disease. At birth, high sensitivity-C reactive protein (hs-CRP), a prognostic marker of cardiovascular disease, is significantly higher in SGA than in appropriate for gestational age (AGA) infants. Aim: To measure aortic and carotid intima-media thickness (aIMT, cIMT) and blood pressure (BP) in children (aged 3-5 years) who were born SGA and AGA, and to assess the correlation between hs-CRP concentrations obtained at birth and these haemodynamic variables. Methods: Umbilical cord hs-CRP concentrations were obtained in 38 neonates. In the same subjects aged 3-5 years, aIMT and cIMT were measured by high-resolution ultrasound scan, in the dorsal arterial wall. Anthropometric variables and BPs were obtained for each child. Results: Maximum (median 0.700 mm, range 0.500-1.080 vs 0.650 mm, 0.400-0.860; p=0.32) aIMTs were similar between children who were born SGA (n=17) and AGA (n=21), respectively. Concentrations of hs-CRP were not correlated with IMTs. In children who were born SGA, systolic BP was significantly correlated with umbilical cord hs-CRP concentrations (r=0.60; p=0.009). Conclusions: Children who were born SGA have a higher, although not significant, aortic thickening than those who were born AGA. Umbilical cord hs-CRP concentrations do not seem to be involved in this process. Instead, hs-CRP concentrations were significantly related to systolic BP values in children who were born SGA, suggesting that hs-CRP at birth could be associated with sympathetic system hyperactivity and with the stress response during childhood.
