Rosiglitazone treatment reduces serum A-SAA levels and adipose A-SAA secretion in obese individuals independent of changes in body weight or fat mass.
This study shows that the drug rosiglitazone can significantly reduce inflammatory markers (A-SAA) in obese individuals without requiring weight loss. This suggests that some medications target specific inflammatory pathways in fat tissue directly. While this is a specific drug finding, it underscores that metabolic health involves complex hormonal signaling that can be modulated pharmacologically, independent of simple caloric balance.
There were no statistically significant changes in body weight or fat mass in these individuals during the 12-wk intervention. Nevertheless, serum A-SAA levels decreased by a mean of 37% after treatment (p = 0.033)... Thus, rosiglitazone reduced adipose A-SAA secretion and lowered serum A-SAA levels with no significant change in BMI or fat mass.
Why this rating
Small sample size (n=8) but clear statistical significance and mechanistic validation in vitro.
