PurposeAcute renal failure (ARF) is the most important complication of rhabdomyolysis. Serial measurements of blood myoglobin might be useful for predicting rhabdomyolysis-induced ARF.MethodsThirty patients with rhabdomyolysis were examined. The causes of rhabdomyolysis were trauma, burns, and ischemia, among others. Serial blood myoglobin levels were measured by immunochromatography, and the peak value was determined. The relationship between blood myoglobin levels and the incidence of ARF was evaluated.ResultsThe median peak blood myoglobin level was 3335 ng/mL. Acute renal failure occurred in 12 patients (40%). Nine patients (30%) underwent renal replacement therapy. Peak creatine kinase and peak blood myoglobin levels in the ARF group were significantly higher than those in the non-ARF group. Three patients in the ARF group were treated with renal replacement therapy before occurrence of uremia because of extremely high levels of blood myoglobin (>10 000 ng/mL). Receiver operating characteristic analysis showed that the area under the curve for blood myoglobin that predicted ARF was 0.88, and the best cutoff value for blood myoglobin was 3865 ng/mL.ConclusionsThe peak value for blood myoglobin might be a good predictor of rhabdomyolysis-induced ARF. Early renal protective therapies should be considered for patients with rhabdomyolysis at high risk of ARF.  相似文献

Purpose

This study aimed to determine the clinical factors in predicting acute renal failure (ARF) in rhabdomyolysis and investigate the potential risk of renal replacement therapy (RRT).

Basic Procedures

From 2006 to 2011, we retrospectively analyzed 202 patients 65 years or younger with a definite diagnosis of rhabdomyolysis and serum creatinine phosphokinase levels greater than 1000 IU/L. The related clinical factors were analyzed in the patients with ARF caused by rhabdomyolysis. In addition, receiver operating characteristic curves were used to establish the appropriate cutoff values of serum biomarkers in predicting ARF.

Main Findings

The most common causes of rhabdomyolysis were trauma (n = 54; 26.7%) and infections (n = 37; 18.3%). Of the 202 patients, 29 (14.4%) developed ARF, and RRT was indicated for 5 of these 29 patients. Predictive factors for ARF were dark urine, initial and peak serum myoglobin level, rhabdomyolysis caused by body temperature change, and an elevated serum potassium level. Receiver operating characteristic analysis showed that the best cutoff value of initial serum myoglobin level for predicting ARF was 597.5 ng/mL. Risk factors for RRT in patients with ARF were etiologies of rhabdomyolysis, peak blood urea nitrogen and creatinine levels, and the creatinine phosphokinase level on the third day as rhabdomyolysis developed.

Principal Conclusions

Age, dark urine, etiologies, serum levels of blood urea nitrogen, creatinine and potassium, and initial and peak serum myoglobin levels may serve as important factors in predicting ARF in patients with rhabdomyolysis. We suggest that the appropriate cutoff value of initial serum myoglobin for predicting ARF is 600 ng/mL.  相似文献

Thirty six patients suffering from myocardial infarction were investigated by assay of their serum myoglobin, total creatine kinase and creatine kinase isoenzyme MB activities. Determination of serum myoglobin presents, with regard to creatine kinase MB, two major advantages: a very early increase after the onset of the pain (about three hours later) and a very quick clearance, allowing the diagnosis of a second episode of necrosis after about one day.  相似文献

Rhabdomyolysis secondary to lovastatin therapy   总被引:3,自引:0,他引:3  
We report a case of lovastatin-induced rhabdomyolysis and resulting life-threatening renal failure. Lovastatin, a hypocholesterolemic agent, decreases endogenous cholesterol synthesis by inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase (EC 1.1.1.88). This agent has been implicated in causing rare serious side effects in various clinical settings; however, the mechanism of these adverse reactions is not understood. The clinical course of our patient was characterized by profound muscle weakness with marked increases in serum creatine kinase and myoglobin. Light- and electron-microscopic studies of skeletal muscle of our patient demonstrated a noninflammatory myopathy suggestive of ongoing rhabdomyolysis with vacuolization and focal degeneration of myocytes. The patient's symptoms and the laboratory values referable to rhabdomyolysis resolved after discontinuation of the drug. We speculate that the rhabdomyolysis was due to mitochondrial damage secondary to inadequate synthesis of coenzyme Q and heme A, members of the electron-transport system of the inner mitochondrial membrane.  相似文献

Introduction: Chlorophenoxy herbicides are used widely for the control of broad-leaved weeds. They exhibit a variety of mechanisms of toxicity including dose-dependent cell membrane damage, uncoupling of oxidative phosphorylation, and disruption of acetylcoenzyme A metabolism. Between January 1962 and January 1999, 66 cases of chlorophenoxy herbicide poisoning following ingestion were reported in the literature. Features following ingestion: Adjuvants in the formulations may have contributed to some of the features observed. Vomiting, abdominal pain, diarrhea, and, occasionally, gastrointestinal hemorrhage were early effects. When present, hypotension was predominantly due to intravascular volume loss, although vasodilation and direct myocardial toxicity may have contributed in some cases. Neurotoxic features included coma, hypertonia, hyperreflexia, ataxia, nystagmus, miosis, hallucinations, convulsions, fasciculation, and paralysis. Hypoventilation occurred not infrequently, usually in association with central nervous system depression, but respiratory muscle weakness was a factor in the development of respiratory failure in some patients. Myopathic symptoms including limb muscle weakness, loss of tendon reflexes, and myotonia were observed and increased creatine kinase activity was noted in some cases. Other clinical features reported included metabolic acidosis, rhabdomyolysis, renal failure, increased aminotransferase activities, pyrexia, and hyperventilation. Twenty-two of 66 patients died. Features following dermal and inhalational exposure: Substantial dermal or inhalational 2,4-dichlorophenoxyacetic acid exposure has occasionally led to systemic features but no such reports have been published in the last 20 years and no fatalities have been reported at any time. Substantial dermal exposure has been reported to cause mild gastrointestinal irritation after a latent period followed by progressive mixed sensory-motor peripheral neuropathy. Mild, transient gastrointestinal and peripheral neuromuscular symptoms have also occurred after occupational inhalation exposure, with or without dermal exposure. Management: In addition to supportive care, alkaline diuresis to enhance herbicide elimination should be considered in all seriously poisoned patients. Limited clinical data suggest that hemodialysis produces similar herbicide clearance to alkaline diuresis without the need for urine pH manipulation and the administration of substantial amounts of intravenous fluid in an already compromised patient. Conclusions: While chlorophenoxy herbicide poisoning is uncommon, ingestion of a chlorophenoxy herbicide can result in serious and sometimes fatal sequelae. In severe cases of poisoning, alkaline diuresis or hemodialysis to increase herbicide elimination should be considered.  相似文献

Rhabdomyolysis, a clinical syndrome caused by damage to skeletal muscle and release of its breakdown products into the circulation, can be followed by acute kidney injury (AKI) as a severe complication. The belief that the AKI is triggered by myoglobin as the toxin responsible appears to be oversimplified. Better knowledge of the pathophysiology of rhabdomyolysis and following AKI could widen treatment options, leading to preservation of the kidney: the decision to initiate renal replacement therapy in clinical practice should not be made on the basis of the myoglobin or creatine phosphokinase serum concentrations.  相似文献

Objective Myoglobin kinetics of removal from the circulation were studied in patients following massive rhabdomyolysis, to see if myoglobin remains for long in the circulation in the anuric state and if myoglobin elimination was affected by therapeutic manipulation such as haemofiltration or haemodialysis.Design Randomised and controlled study.Setting Intensive care unit of a tertiary care teaching hospital.Patients 26 patients of rhabdomyolysis whose serum myoglobin exceeded more than 500 nmol/l. Thirteen patients developed acute renal failure and underwent treatment with blood purification (Group HD). The remaining 13 patients did not require treatment with blood purification (control subjects, Group non-HD).Interventions In patients of group HD, twelve were treated with haemofiltration and/or haemodialysis. One was treated with peritoneal dialysis. The patient of group non-HD were treated with fluid infusion alone.Measurements and results The serum concentrations of myoglobin were serially determined. The highest levels of myoglobin was 1641±484 nmol/l (mean±SEM) in the group non-HD and were 8957±2300 in the group HD. In the group non-HD, the blood myoglobin fell exponentially once myoglobin release into the circulation ceased. This was also noted in the group HD. The exponential decrease was observed even on the days when the patient passed little urine or treatment with blood purification was not performed.Conclusion In patients with massive myoglobinaemia, the blood myoglobin rapidly fell independent of renal function or any therapeutic manipulation. The results indicate that extrarenal factors played a major role in disposing circulating myoglobin in such patients.  相似文献

OBJECTIVE: To evaluate the length of the effects of long-term (48 hrs), low-dose dopamine infusion on both renal function and systemic hemodynamic variables in stable nonoliguric critically ill patients. DESIGN: Prospective, single-blind, controlled clinical study. SETTING: University hospital, 19-bed multidisciplinary intensive care unit. PATIENTS: Eight hemodynamically stable, critically ill patients with a mild nonoliguric renal impairment (creatinine clearance between 30 and 80 mL/min). INTERVENTIONS: Each patient consecutively received 4 hrs of placebo, followed by a 3 microg/kg/min dopamine infusion during 48 hrs, then a new 4-hr placebo period. We measured cardiac output and other hemodynamic variables by using a pulmonary artery catheter. The bladder was emptied to determine urine volume and to collect urine samples. Measurements were performed at six times: after the initial control of 4 hrs of placebo (C1); after 4 hrs (H4), 8 hrs (H8), 24 hrs (H24), and 48 hrs (H48) of dopamine infusion; and after the second control of 4 hrs of placebo (C2). MEASUREMENTS AND MAIN RESULTS: We saw no significant change in systemic hemodynamic variables with dopamine at all times of infusion. Diuresis, creatinine clearance, and the fractional excretion of sodium (FENa) at C1 and C2 were not different. Urine flow, creatinine clearance, and FENa increased significantly 4 hrs after starting dopamine (for all these changes, p < .01 vs. C1 and C2). The maximum changes were obtained at H8, with an increase of 50% for diuresis, 37% for creatinine clearance, and 85% for FENa (for all these changes, p < .01 vs. C1 and C2). But these effects waned progressively from H24, and both creatinine clearance and FENa at H48 did not differ from control values. CONCLUSIONS: In stable critically ill patients, preventive low-dose dopamine increased creatinine clearance, diuresis, and the fractional excretion of sodium without concomitant hemodynamic change. These effects reached a maximum during 8 hrs of dopamine infusion. But despite a slight persistent increase in diuresis, improvement in creatinine clearance and FENa disappeared after 48 hrs. According to these data, it is likely that tolerance develops to dopamine-receptor agonists in critically ill patients at risk of developing acute renal failure.  相似文献

Changes in values for myoglobin, total creatine kinase (EC 2.7.3.2), and creatine kinase B-subunit in the serum of patients with thyroid disease are compared with values for these during the 24-h after myocardial infarction. Concentrations of all three of these muscle-derived proteins were significantly higher than normal in patients with primary hypothyroidism, and declined with treatment. Values for total creatine kinase activity were below-normal in hyperthyroid patients, but increased after treatment. Values for total creatine kinase and, to a lesser extent, myoglobin in hypothyroidism extend into the range of values observed after myocardial infarction. The mechanism of the changes in these analytes in hypothyroidism may be related to increased leakage from skeletal-muscle cells or diminished clearance from the circulation, or both.  相似文献

Rhabdomyolysis is a clinical syndrome defined by muscle breakdown and subsequent release of intracellular contents. There are many etiologies of rhabdomyolysis, classified here as congenital and acquired; compartment syndrome secondary to trauma with reperfusion injury is one common precipitating factor. Regardless of the underlying etiology, the pathophysiology follows a similar pathway via myocyte destruction and release of myoglobin into the systemic circulation. Rhabdomyolysis-induced renal failure is caused by the precipitation of myoglobin in the renal tubules which is enhanced under acidic conditions. A high index of clinical suspicion is required to promptly recognize rhabdomyolysis, especially in the unconscious patient. Presenting symptoms include tea-colored urine and muscle weakness or fatigue. The diagnosis is confirmed most reliably with the finding of elevated serum creatine kinase levels. Early, aggressive resuscitation with either normal saline or lactated Ringer's solution to maintain an adequate urine output is the most important intervention in preventing the development of acute renal failure. There is insufficient clinical evidence supporting the routine administration of diuretics and bicarbonate to protect against the development of acute renal failure.  相似文献

OBJECTIVE: To describe the fifth reported instance, as of February 15, 2006, of a severe interaction between simvastatin and amiodarone and hypothesize inhibition of CYP3A4 as the major mechanism. CASE SUMMARY: A 72-year-old white man (178 cm, 77.2 kg) with diabetes mellitus, hyperlipidemia, hypertension, and mild azotemia was hospitalized on September 21, 2004, with thigh weakness, achiness, and dark urine for 7 days. Coronary artery bypass had been performed on July 7, 2004. Amiodarone 200 mg/day was started on July 10, and simvastatin 80 mg/day was initiated on August 13. Laboratory testing on the present admission included creatine kinase (CK) 19,620 U/L (reference range 60-224), blood urea nitrogen 50 mg/dL, creatinine 2.6 mg/dL, aspartate aminotransferase (AST) 912 U/L (30-60), alanine aminotransferase (ALT) 748 U/L (30-60), urine myoglobin 71,100 microg/L (<50), and serum myoglobin 13,877 microg/L (<110). Simvastatin and amiodarone were discontinued, and the patient was hydrated with forced alkaline diuresis. Thirteen days later, his CK was 323 U/L, creatinine 1.7 mg/dL, ALT 145 U/L, and AST 37 U/L. DISCUSSION: Simvastatin is metabolized primarily by CYP3A4, and amiodarone is a recognized inhibitor of this enzyme. This may, therefore, account for the presumed drug interaction. CONCLUSIONS: An objective causal assessment suggests that rhabdomyolysis, renal failure, and possibly hepatotoxicity were probably related to an amiodarone-simvastatin interaction.  相似文献

Two groups of young men taking part in a 24-day training courseinvolving increasingly severe exercise were studied. Serum myoglobin,creatine kinase, creatine kinase-MB, transaminases, lactatedehydrogenase, urea, creatinine, calcium and uric acid wereestimated at intervals. During the first few days, increasesin myoglobin and muscle enzymes correlated with the severityof the preceding exercise. Increases in myoglobin and muscleenzymes after the final most severe exercising were less thanwith the initial exercising, demonstrating the effect of physicaltraining. The changes in myoglobin and the muscle enzymes correlatedclosely. Elevated myoglobin levels persisted for over 24 hours.There was no consistent correlation between changes in myoglobinand uric acid, both of which have been considered responsiblefor the renal failure which may occur with rhabdomyolysis.  相似文献

Rhabdomyolysis ranges from an asymptomatic illness with elevation in the creatine kinase level to a life-threatening condition associated with extreme elevations in creatine kinase, electrolyte imbalances, acute renal failure and disseminated intravascular coagulation. Muscular trauma is the most common cause of rhabdomyolysis. Less common causes include muscle enzyme deficiencies, electrolyte abnormalities, infectious causes, drugs, toxins and endocrinopathies. Weakness, myalgia and tea-colored urine are the main clinical manifestations. The most sensitive laboratory finding of muscle injury is an elevated plasma creatine kinase level. The management of patients with rhabdomyolysis includes early vigorous hydration.  相似文献

Severe damage of skeletal muscle, referred to as rhabdomyolysis, is the cause of 10% of acute kidney injury (AKI) cases and AKI complicates 13–50% of traumatic or nontraumatic rhabdomyolysis. Hypovolemia and the direct nephrotoxic effect of myoglobin are thought to be the main factors involved in rhabdomyolysis-induced AKI. Myoglobin promotes kidney injuries through vasoconstrictive properties, proximal tubular injuries, and distal obstruction. Recently, we demonstrated that macrophages influence the long-term prognosis of this disease by exerting proinflammatory as well as profibrotic properties. Clinical management relies on early diagnosis (creatine kinase > 5,000 UI/l) and fluid resuscitation using isotonic sodium chloride. Despite optimal rehydration, patients can develop AKI and require renal replacement therapy (RRT). Severe hyperkalemia or metabolic acidosis is the main cause of RRT. Thus, intermittent hemodialysis rather than continuous RRT should be used as frontline RRT, if available. To date, alkalinization, as well as prophylactic intermittent hemodialysis with high cut-off membrane, did not demonstrate superiority on long-term renal function compared to conventional approach. While global prognosis is depending upon the cause of rhabdomyolysis, mortality increases from 22% to 59% as soon as patients develop AKI. Long-term prognosis is unknown. Animal models demonstrated that rhabdomyolysis can lead to renal fibrosis after several months of followup. This suggests that patients with rhabdomyolysis should be considered as at high risk to develop chronic kidney disease and therefore referred to nephrologists to minimize long-term consequences of chronic kidney disease.  相似文献
