Summary

A 44-year-old man was referred because of hyperCKaemia (elevated CK activity). CK ranged from 1300 to 2200 IU/L (normal < 171). Before referral some investigations were performed. TSH was normal. HyperCKaemia was initially considered to be related to the use of simvastatin, but four months after withdrawal of this drug, CK was still markedly elevated.

He did not complain about muscle weakness, muscle cramps, or myalgia. Previous history disclosed diabetes mellitus type 2, hypertension, and Asperger syndrome. Medication included metoprolol/hydrochlorothiazide, enalapril, and metformin. Family history was negative for neuromuscular disorders.
