The purpose of the present study was to investigate plasma levels of ACE (angiotensin-converting enzyme) activity, angiotensin and catecholamines in 8- to 13-year-old children and to determine whether there are correlations between the components of these systems with both birthweight and BP (blood pressure) levels. This clinical study included 66 children (35 boys and 31 girls) in two groups: those born at term with an appropriate birthweight [AGA (appropriate-for-gestational age) group, n=31] and those born at term but with a small birthweight for gestational age [SGA (small-for-gestational age) group, n=35]. Concentrations of angiotensin, catecholamines and ACE activity were determined in plasma. Circulating noradrenaline levels were significantly elevated in SGA girls compared with AGA girls (P=0.036). In addition, angiotensin II and ACE activity were higher in SGA boys (P=0.024 and P=0.050 respectively). There was a significant association of the circulating levels of both angiotensin II and ACE activity with BP levels in our study population. Although the underlying mechanisms that link restricted fetal growth with later cardiovascular events are not fully understood, the findings in the present study support the link between low birthweight and overactivity of both sympathoadrenal and renin\u2013angiotensin systems into later childhood.<\/jats:p>","DOI":"10.1042\/cs20070284","type":"journal-article","created":{"date-parts":[[2008,2,1]],"date-time":"2008-02-01T10:55:18Z","timestamp":1201863318000},"page":"375-380","update-policy":"https:\/\/doi.org\/10.1042\/crossmark_policy","source":"Crossref","is-referenced-by-count":66,"title":["Circulating renin\u2013angiotensin system and catecholamines in childhood: is there a role for birthweight?"],"prefix":"10.1042","volume":"114","author":[{"given":"Maria\u00a0C.\u00a0P.","family":"Franco","sequence":"first","affiliation":[{"name":"Division of Nephrology, School of Medicine, Federal University of S\u00e3o Paulo, 04023-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dulce\u00a0E.","family":"Casarini","sequence":"additional","affiliation":[{"name":"Division of Nephrology, School of Medicine, Federal University of S\u00e3o Paulo, 04023-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcela\u00a0S.","family":"Carneiro-Ramos","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Sciences, University of S\u00e3o Paulo, 05508-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ana\u00a0L.","family":"Sawaya","sequence":"additional","affiliation":[{"name":"Department of Physiology, Federal University of S\u00e3o Paulo, 04023-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria\u00a0L.\u00a0M.","family":"Barreto-Chaves","sequence":"additional","affiliation":[{"name":"Institute of Biomedical Sciences, University of S\u00e3o Paulo, 05508-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ricardo","family":"Sesso","sequence":"additional","affiliation":[{"name":"Division of Nephrology, School of Medicine, Federal University of S\u00e3o Paulo, 04023-900 S\u00e3o Paulo, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"288","published-online":{"date-parts":[[2008,2,1]]},"reference":[{"key":"2021120120495543700_B1","doi-asserted-by":"crossref","first-page":"938","DOI":"10.1016\/0140-6736(93)91224-A","article-title":"Fetal nutrition and cardiovascular disease in adult life","volume":"341","author":"Barker","year":"1993","journal-title":"Lancet"},{"key":"2021120120495543700_B2","doi-asserted-by":"crossref","first-page":"322","DOI":"10.7326\/0003-4819-130-4-199902160-00019","article-title":"The fetal origins of type\u00a02 diabetes mellitus","volume":"130","author":"Barker","year":"1990","journal-title":"Ann.
