Thanks for posting this information. It isn't clear to me what is the
rationale for the nelfinavir in the women with >250 T cells. Also, which
drugs are the breastfeeding women getting? The same ones they started on?
anyway, it sounds to me like women are getting their drugs daily during at
least 6 months of breastfeeding. Is that the case? If so they are taking 3
costly drugs (combivir is 2 drugs) for which someone is paying or
subsidizing. For prevention of new infections in the infants, wouldn't it be
less expensive to provide ready-to-feed formula? More importantly, are these
very potent meds making their way into the breastmilk drunk by babies who
are not hiv-infected, and how does that affect the babies?
Personally, I believe infected infants should get hiv drugs, and infected
moms should also get hiv drugs, but the idea of non-infected infants
possibly getting these 3 drugs.....That worries me.
