Serum creatinine kinase (CK) levels were recorded in 100 patients with amyotrophic lateral sclerosis (ALS). CK concentrations were elevated in 43% of the patients, with a mean level of 240 U/l and a range of 59-1,327 U/l (male normal < 95 U/l, female normal < 59 U/l). All patients with elevated CK had muscle weakness. Seven patients were initially misdiagnosed as having polymyositis and given high dose corticosteroids without clinical benefit, prior to the diagnosis of ALS. Such diagnostic confusion can be avoided by an awareness that CK levels cannot be used to reliably differentiate between ALS and primary muscle disease such as polymyositis.
