Relationship of creatine kinase to body composition, disease state, and longevity in ALS.

ABSTRACT: Our objective was to explore if creatine kinase (CK) levels correlate with survival in amyotrophic lateral sclerosis (ALS), and whether a correlation is independent of other well-studied predictors such as location of onset, gender, age, fat free mass, spasticity, cramps, and fasciculations. We analyzed data from 80 ALS patients from a 48-week non-interventional longitudinal multicenter nutrition study with long term follow-up. The overall mean CK was 214 ± 191.8 U/l (range 22-1992 U/l). Forty-five percent of patients had at least one high CK value (> 200 U/l), and about half maintained a high CK value, but there was no trend over the study period. Male gender and extremity onset were significantly associated with high CK. In univariate analysis, age, bioelectric impedance spectroscopy (BI
