Anna, I am definitely not an expert here, but one thing that did stick out to me was the graft vs host issue. I attended a seminar put on by Health Education Associates a couple of years ago in Los Angeles, and the topic was "promoting breastfeeding". Among other things, they did a quick run down on the latest in "advantages of breastfeeding" that included some statistics on the effects of breastfeeding on transplant situations later on. The bottom line: having been breastfed as an infant was related to lower rejection incidences, and having been breastfed AND receiving donated organ from a previously breastfed individual brought the lowest risk of organ rejection of all. I'm not sure how this might work into your graft vs host issue, but it does stick in my craw to just throw out breastfeeding. I'm speaking out of my *very* limited knowledge of this particular situation, however, and I look forward to more analysis from those more learned than I. -Lisa P.S. They gave us the most complete bibliography, pages of tiny print, and I'm sure the cited studies are on there somewhere! Unfortunately, it is alphabetized by author and not organized by topic... ************************************************* Lisa Marasco, BA, LLLL, IBCLC [log in to unmask] / [log in to unmask] *************************************************
