Rhabdomyolysis is a syndrome of skeletal muscle injury with release of cellular constituents such as potassium,phosphate,urate and intracellular proteins such as myoglobin into the circulation,which may cause complications including acute kidney injury,electrolyte disturbance and cardiac instability.Abnormal liver function tests are frequently observed in cases of severe rhabdomyolysis.Typically,there is an increase in serum aminotransferases,namely aspartate aminotransferase and alanine aminotransferase.This raises the question of liver injury and often triggers a pathway of investigation which may lead to a liver biopsy.However,muscle can also be a source of the increased aminotransferase activity.This review discusses the dilemma of finding abnormal liver function tests in the setting of muscle injury and the potential implications of such an association.It delves into some of the clinical and experimental evidence for correlating muscle injury to raised aminotransferases,and discusses pathophysiological mechanisms such as oxidative stress which may cause actual liver injury.Serum aminotransferases lack tissue specificity to allow clinicians to distinguish primary liver injury from muscle injury.This review also explores potential approaches to improve the accuracy of our diagnostic tools,so that excessive or unnecessary liver investigations can be avoided. 相似文献

Rhabdomyolysis is a serious and potentially life threatening condition. Although consensus criteria for rhabdomyolysis is lacking, a reasonable definition is elevation of serum creatine kinase activity of at least 10 times the upper limit of normal followed by a rapid decrease of the sCK level to (near) normal values. The clinical presentation can vary widely, classical features are myalgia, weakness and pigmenturia. However, this classic triad is seen in less than 10% of patients. Acute renal failure due to acute tubular necrosis as a result of mechanical obstruction by myoglobin is the most common complication, in particular if sCK is >16.000 IU/l, which may be as high as 100,000 IU/l. Mortality rate is approximately 10% and significantly higher in patients with acute renal failure. Timely recognition of rhabdomyolysis is key for treatment. In the acute phase, treatment should be aimed at preserving renal function, resolving compartment syndrome, restoring metabolic derangements, and volume replacement. Most patients experience only one episode of rhabdomyolysis, mostly by substance abuse, medication, trauma or epileptic seizures. In case of recurrent rhabdomyolysis, a history of exercise intolerance or a positive family history for neuromuscular disorders, further investigations are needed to identify the underlying, often genetic, disorder. We propose a diagnostic algorithm for use in clinical practice. 相似文献

Haemoglobin and myoglobin are haem proteins that play a key role as they help transport oxygen around the body. However, because of their chemical structure, these molecules can exert harmful effects when they are released massively into the bloodstream, as reported in certain pathological conditions associated with rhabdomyolysis or intravascular haemolysis. Once in the plasma, these haem proteins can be filtered and can accumulate in the kidney, where they become cytotoxic, particularly for the tubular epithelium, inducing acute kidney failure and chronic kidney disease. In this review, we will analyse the different pathological contexts that lead to the renal accumulation of these haem proteins, their relation to both acute and chronic loss of renal function, the pathophysiological mechanisms that cause adverse effects and the defence systems that counteract such actions. Finally, we will describe the different treatments currently used and present new therapeutic options based on the identification of new cellular and molecular targets, with particular emphasis on the numerous clinical trials that are currently ongoing. 相似文献

With the awareness of health problems related to obesity, weight reducing diets have become very popular. However, if these meal supplements are not taken as recommended, they can cause considerable harm in high risk individuals. We report a case of a young obese man who developed diabetic ketoacidosis (DKA) followed by rhabdomyolysis and acute renal failure (ARF) after excessive intake of a high carbohydrate containing weight-reducing meal. DKA associated with excessive intake of weight reducing diets has not been reported previously. In people with obesity and insulin resistance improper use of these supplements can cause severe metabolic complications. 相似文献

The goal of surgical positioning is to provide optimal surgical access and visualization while maintaining the patient's safety, with the least physiological compromise. Here, we report a 30-year-old man with an unremarkable past medical history who developed superior vena cava syndrome after a 15-hour retrosigmoid craniotomy for removal of a right cerebellopontine (CP) angle tumor. Compartment syndrome from the head to neck and rhabdomyolysis were recognized, with extensive swelling of his head and neck, markedly swollen soft tissues and necrosis of multiple muscles revealed by computed tomography, and very high concentrations of creatine kinase (CK) and aspartate transaminase. Immediate intensive care and rehabilitation therapy were provided and aimed at maintaining adequate perfusion/oxygenation and decreasing tissue pressure. He was successfully weaned from ventilation on postoperative day (POD) 25, transferred to a general ward on POD 29, and discharged with mild muscular and neurological sequelae on POD 51. Careful adjustment of surgical positioning is crucial for patient safety, especially when positioned at an extreme position in association with prolonged surgery. 相似文献
