PURPOSE: The present study aims to describe initial changes in muscle thickness and composition, muscle growth signaling mediators, and systemic inflammation in critically ill patients after major trauma.
METHODS: This observational study was carried out in a Level-I nonprofit trauma center. Thirty adults requiring mechanical ventilation were assessed within 24 h post-admission. Skeletal muscle wasting was evaluated using ultrasound for muscle thickness and echogenicity along with circulating insulin-like growth factor 1 (IGF-1) and inflammatory cytokines over five consecutive days. Changes over time were assessed using ANOVA repeated-measures analysis with a Bonferroni post-hoc test. Bivariate correlations were evaluated using Pearson or Spearman coefficients.
RESULTS: Over five days, a significant decrease (11%) in rectus femoris thickness (3.91 ± 0.86 to 3.47 ± 0.64, cm, p = 0.01) and an increase (29%) in echogenicity (62.1 ± 13.1 to 80.4 ± 17.3, AU, p < 0.01) were observed among the 30 patients included in this study. Circulating levels of IGF-1 exhibited a 38% reduction (68.8 ± 43.6 to 42.4 ± 29.4, ng/mL, p = 0.01). Furthermore, pro-inflammatory cytokine (IFN-y) increased by 17% (4.83 ± 1.39 to 5.66 ± 1.61, pg./mL, p = 0.02) from day 1 to day 5.
CONCLUSIONS: These findings reveal substantial thickness and muscle composition alterations within 48 h post-admission, worsening over five days. Despite standard rehabilitation care, changes in IGF-1 and IFN-y levels suggest early declines in muscle growth stimulus and increased inflammation.
