[Hematopoietic changes in states of severe malnutrition in anorexia nervosa].

This work, studying the effects of severe caloric deficiency on the medullary activity, shows that, in anorexia nervosa, there are some modifications of the stem cells, in particular in the granulocyte line and that its rarefaction is proportional to the intensity of denutrition. The reduction of the stock of stem cells, for which two hypotheses have been raised, could be a factor of vulnerability to infections in these patients in case of severe denutrition.
