DHEA, either alone at 50mg daily or in combination with an aromatase inhibitor (atamestane at 100mg) was studied for 36 weeks in otherwise healthy an non-hospitalized older men with low scores on physical strength (frailty).
Testosterone increased in all groups, with the DHEA+AI group increasing more than double that of DHEA or AI alone (8.5, 3.5, 4.9nmol/L respectively), DHEA+AI had about 1.3rd the increase in estrogen seen in DHEA, while AI saw a decrease relative to placebo. IGF-1 increased in all groups, but only significantly in the combination. The combination seemed to improve body composition, but was statistically insignificant.
Cognitive decline was measured via MMSE but showed no influence with DHEA, and the changes in IGF binding proteins were too variable to be significant (although an interaction seemed to be present)
