Association of muscle instability and long-term prophylaxis in hereditary angioedema

Bradykinin appears to cause instability of skeletal muscle, causing CK release with even minor exercise. The effect of increases in bradykinin in HAE on muscle needs further research but may account for some of the atypical HAE symptoms patients often describe and which are noted in quality-of-life assessments. LTP, therefore, may confer additional benefits beyond reduction of HAE symptoms, potentially contributing to stabilization of skeletal muscle and improvement of fatigue and weakness.
