Vitamin D as a treatment of tuberculosis

There is now a lot of hype around the usefulness of vitamin D in the treatment of tuberculosis (scienceblog:doi:10.1164/rccm.200701-007OC ). The authors mention even their previous review (scienceblog:doi:10.1016/j.jsbmb.2006.12.052:) summarizing 13 studies between 1947 and 1998.
I am quite sure that they missed much earlier research as vitamin D has been discovered as early as 1922 ( ). At least in 1929 there was a congress report at the “Deutsche Gesellschaft für Lichtforschung” published in Naunyn-Schmiedeberg’s Archives of Pharmacology, Volume 147, Numbers 1-3 / Dezember, p 60-61, 1929 scienceblog:doi:10.1007/BF01946034 of 58 patients treated with 1-3 x 16 mg / daily vigantol with an excellent outcome. Mortality within 1 year was reduced to 50%, with nearly full recovery of working capacity in all other trial participants.
