Summary

Actually, there is an increasing number of arguments for a premature origin of chronic adult's diseases, as the chronic obstructive pulmonary disease (COPD). Several factors interacting with the foetal or postnatal lung growth are associated with early and long-lasting respiratory functional changes susceptible to contribute very significantly to the arisen of a COPD in the adulthood. It is possible that these situations reflect phenomena of premature cellular senescence, recently involved in the physiopathology of the COPD. An in utero exposition to cigarette smoking is one of these situations, because it is known to induce, not only functional respiratory changes, but also multiple diseases in the child which could testify of cellular ageing phenomena. Our project aims to demonstrate that in utero smoking is associated with markers of premature cellular senescence in newborn children The study will be driven in human newborn child's, with comparison of the length of the telomeres in circulating lymphocytes (umbilical blood is collected), according to the exposure in in utero smoking and also according to the degree of hypotrophy. This study will be a pilot study completed by an animal experimental study.
