Abstract/OtherAbstract:
AIM: The need for a non-invasive diagnosis of the effects of ethanol in utero on the development of the intestine in humans led us to look for a serum marker of the structural integrity of the intestine. We propose apolipoprotein A-IV (apoA-IV) as a possible candidate. In humans this protein is synthesized only by intestinal mucosa, it is expressed in the enterocyte of the foetus from 20 weeks of gestation, and it is released to the blood stream after synthesis. METHODS: We measured the levels of apoA-IV in the umbilical cord serum of neonates whose mothers had consumed alcohol during pregnancy and neonates born to women who had not (controls). The gestational age at delivery of the cases studied ranged from 36 to 42 weeks. ELISA and Western blot analysis were used. RESULTS: There was no difference in the mean body weight of neonates from either group. Nevertheless, exposure to ethanol in utero significantly reduced (by about 30%) the apoA-IV levels in serum at birth, regardless of body weight. CONCLUSION: Our findings suggest that circulating apoA-IV levels could be used as a clinical marker of the prenatal effects of ethanol on the structural integrity of the intestine. Neonatal diagnosis of these intestinal effects could improve post-natal outcome.
