Further Inpatient Care
- If acute renal failure occurs in patients with McArdle disease (glycogen-storage disease type V), hemodialysis and appropriate monitoring of fluid and electrolyte status may be necessary.
Deterrence/Prevention
- Because acute renal failure is precipitated by rhabdomyolysis in McArdle disease, avoidance of strenuous and/or isometric exercise may be indicated.
Complications
- Acute renal failure may complicate muscle necrosis and myoglobinuria following vigorous exercise.
Prognosis
- McArdle disease typically has a relatively benign nature when severe rhabdomyolysis is avoided. Limitation or adaptation of exercise to avoid symptoms may be necessary. Acute renal failure requires appropriate treatment. Progression to chronic renal disease has not been described, but acute renal failure due to myoglobinuria is potentially life threatening.
Patient Education
- Educate patients about modifying their activity in order to prevent rhabdomyolysis. Patients should avoid extreme isometric exercise.
- Educate patients about the “second wind” phenomenon.
