Creatine kinase activity in sickle cell disease

J Clin Pathol. 1989 Jul;42(7):712-5. doi: 10.1136/jcp.42.7.712.

Abstract

Creatine kinase activity was measured in 28 patients in the steady state of sickle cell disease and ranged from 4-45 IU/l, comparable with that found in healthy adult caucasians. Creatine kinase activity was also measured in 14 patients admitted consecutively for the treatment of vaso-occlusive sickle cell crises. Creatine kinase activity remained within the normal range in eight of these 14 patients throughout their admission; none had muscle pain or a chest syndrome. In the remaining six, three with muscle pain and three with a chest syndrome, increased activity was found on one or more days. A further 17 patients with vaso-occlusive sickle cell crises, associated with muscle pain, were studied. Creatine kinase activity was significantly raised in all 17, the mean creatine kinase activity for men was 578.8 IU/l and 210.6 IU/l for women, with the highest values (up to 1790 IU/l) found in those who had exercised before admission. Measurement of creatine kinase activity may therefore be a useful marker of muscle perturbation due to sickling.
