Ferritin and LDL-cholesterol as biomarkers of fat-free mass loss in ALS

Abstract : The availability of longitudinal clinical and biological data led us to wonder whether these parameters could be used to predict disturbances in body composition during ALS progression. Bioelectrical impedance analysis (BIA), as well as clinical and biological parameters (blood lipids and ferritin), were collected one year after diagnosis in ALS patients. The correlations were evaluated by the Spearman test. Performances to predict the evolution of BIA parameters during ALS evolution were evaluated by ROC analysis. Forty-two ALS patients were enrolled. Variations in FFM over one year were correlated to the variations in LDL-cholesterol (r = 0.53, p = 0.002) and ferritin (r = -0.58, p = 0.0002). To predict FFM loss, an increase in ferritin over 9 µg/L had a sensitivity of 90.0% and a specificity of 80.0% (p < 0.0001). Ferritine evolution would allow to easily follow the FFM without BIA during ALS. In addition, an adapted nutritional treatment based on this biological parameter might slow down ALS progression.
