Higher baseline levels of Myostatin are associated with significant functional decline (Gait Speed and 6MWD) in older adults with sarcopenia, while inflammatory markers (IL-6, hsCRP) show less consistent or no correlation with functional decline.

While not yet a standard clinical test, high Myostatin levels may predict functional decline in sarcopenic older adults. In contrast, common inflammatory markers (CRP, IL-6) did not correlate with functional decline in this study, suggesting they may not be the primary drivers of functional loss in this population.

when the median of Myostatin blood level (2651.55 pg/mL) was used to determine the two subgroups, we observed that the group of patients with a “high” level of myostatin (> 2651.55 pg/L) had a significant reduction in the GS/400MWT change from baseline to Month 6/EOS of -0.05 ± 0.208 m/s (p = 0.044)... No correlation was shown with 400MWT and no correlation was observed for both assessments with IL-6
