Beware of 'normal' creatine kinase levels in HIV-associated polymyositis.

Aldolase levels in dermatomyositis and polymyositis with normal creatine kinase

Aldolase levels in dermatomyositis and polymyositis with normal creatine kinase levels.

Dermatomyositis without creatine kinase elevation. A poor prognostic sign.

Serum muscle enzyme levels are usually elevated in patients with untreated polymyositis and dermatomyositis. Creatine kinase is the muscle enzyme most often used to diagnose inflammatory myopathies. Seven patients with dermatomyositis and normal creatine kinase levels are described. Five of the seven patients had either an associated malignancy or severe interstitial lung disease. The one-year ...

An Analysis of the Creatine Kinase Isoenzyme and Cardiac Troponin T Levels in a Polymyositis Patient

From an extensive model developed to interpret physiological processes we are able to show that the observed elevated creatine kinase-myoglobin (CK-MB) and serum concentration of cardiac troponin T (cTnT) values for a particular patient are associated with the inflammatory disease, polymyositis, and not myocardial injury. This highlights that caution must be exercised in using elevated CK-MB an...

Serum myoglobin and creatine kinase concentrations in patients with polymyositis or dermatomyositis.

SIR, Measurement of serum creatine kinase is an accepted procedure in the follow up of patients with polymyositis or dermatomyositis. This parameter is nearly always raised at some point in the illness, and serves as a useful guide in making decisions regarding therapy. There are preliminary reports on the importance of determination of serum myoglobin levels in such patients, however, suggesti...
