Hi Jenny,

There HAVE been studies before comparing different glucocorticoids at different dosing regimens, but generally with very small numbers of patients (such as this one)  http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=pubmed&dopt=Abstract&list_uids=934750&query_hl=2

I think it is a great idea to do an updated study! Hopefully they will take into account the correct relative potencies of the different glucocorticoids; also the timing of doses relative to the different half-lifes of each of the different medications, so that they know they are comparing apples-to-apples.  At any rate, I think it is a great idea and would love to hear more specifics.

Good luck whatever you decide!
