rhabdomyolisis and exercise

Rui Costa, Rui Castro, Alexandre Costa, Ricardo Taipa, Ramon Vizcaíno, Teresa Morgado
McArdle disease typically presents in childhood or young adults with myalgia, exercise intolerance, cramps and myoglobinuria. Deficiency of myophosphorylase enzyme results in inability to degrade glycogen stores, causing glycogen accumulation in muscle tissue and energy deficit. Evolution with rhabdomiolysis may occur and can be complicated with acute kidney injury but rarely, in about 11% of cases, is the initial disease manifestation. We report a case of McArdle Disease in a 38-year-old male patient. The disease went unrecognized despite previous symptoms (myalgia, exercise intolerance and single myoglobinuria episode) until an episode of rhabdomyolisis complicated with oliguric acute kidney injury requiring hemodialysis...

INTRODUCTION: Mc Ardles disease, also known as Type V glycogen storage disease, is a rare deficiency of the enzyme glycogen phosphorylase in muscle cells, inherited as an autosomal recessive trait. In the absence of this enzyme, muscles cannot break down glycogen during exercise, so in patients affected by McArdles disease even moderate physical activity produces cramps, pain and fatigue. Anaerobic activity leads to severe fixed contractures and rhabdomyolisis with myoglobinuria and raised serum creatine-kinase, which, in turn, can lead to acute renal failure...

Rhabdomyolysis is a syndrome that results from the destruction of the skeletal muscle. The one produced by exercise is observed after an intense physical effort. A form of high-intensity exercise called spinning or indoor cycling that involves using a stationary bicycle, has been exceptionally reported as a generating factor of muscular damage in the medical literature. A retrospective study was performed to assess the clinical presentation and the complications shown by nine patients who experienced rhabdomyolysis caused by indoor cycling...

Exercise intolerance, sometimes complicated by rhabdomyolysis is a frequent complaint of patients consulting in neuromuscular centers. It may be the main clinical manifestation of many metabolic myopathies and muscular dystrophies. The first step of diagnosis relies on the performance of in vivo metabolism investigations: forearm or bicycle ergometer exercise tests, phosphorus nuclear magnetic resonance spectroscopy. A few enzymatic defects may be directly assessed on blood samplings, in particular carnitine palmitoyltransferase deficiency; but muscle biopsy is necessary in most cases in order to precise the etiology...

Rhabdomyolisis most commonly occurs after muscle injury, alcohol ingestion, drug intake and exhaustive exercise. Prolonged muscle compression at the time of surgery may produce this complication. Obesity has been reported as a risk factor for pressure-induced rhabdomyolysis, but no reports associated with bariatric surgery could be found in the literature. We report 3 superobese patients who developed rhabdomyolysis after bariatric surgery. This complication was attributed to direct and prolonged pressure of the bed against the dorsal and gluteal muscles...
