Utility of Serum Creatinine, Creatine Kinase and Urinary Myoglobin in Detecting Acute Renal Failure due to Rhabdomyolysis in Trauma and Electrical Burns Patients

Rhabdomyolysis due to trauma and burns is an important cause of acute renal failure (ARF) secondary to myoglobinuria. To prevent morbidity and mortality from ARF due to rhabdomyolysis, early detection of ARF by monitoring the biochemical parameters such as serum creatinine, serum creatine kinase (CK), and urinary myoglobin (UM) can be helpful. The aims of the study were (1) to detect ARF due to rhabdomyolysis using serum creatinine, serum CK, and UM in trauma and electrical burn patients (2) to compare utility of these parameters in early prediction of ARF in patients of rhabdomyolysis. A total of 50 patients with trauma and electrical burns were included in the study. Serum creatinine, serum CK, and UM measurements were done at the time of admission and after 48 h. Diagnosis of ARF was made in the patients by Rifle’s criteria. The presence of significant elevation of creatinine, serum CK, and UM at the time of admission and after 48 h was compared in patients developing ARF by Fisher’s exact test. Fifteen of the 50 patients developed ARF as per the defined criteria. Of these, 9 patients (60 %) had raised level of serum creatinine above 1.4 mg% at admission and 14 patients (93.33 %) had CK level >1250 U/L at admission, whereas UM was positive in 6 (40 %) patients. Serum creatinine was significantly raised in all of the 15 ARF patients (100 %) after 48 h of admission and serum CK was raised in 14 of the 15 ARF patients (93.33 %). UM was negative in all the patients after 48 h of admission. Statistical analysis showed that rise in serum CK on admission was significantly increased in patients developing ARF as compared with serum creatinine and UM (P < 0.0001). On admission, CK is a better predictor of ARF due to rhabdomyolysis than creatinine and UM. Initial creatinine is a better predictor of ARF due to rhabdomyolysis than UM. UM assay is not a good investigation for early prediction of ARF in rhabdomyolysis.     

Case of fulminant type 1 diabetes mellitus complicated with acute renal failure treated with continuous hemodiafiltration

A 50-year-old male patient developed diabetic ketoacidosis with shock, acute renal failure treated with continuous hemodiafiltration (CHDF) and high serum CPK levels. Because of acute onset of ketoacidosis accompanied with an elevation of serum amylase, and negative findings of antibodies associated with autoimmune type 1 diabetes mellitus, he was diagnosed as a fulminant type 1 diabetes mellitus, which is a newly established subtype of type 1 diabetes mellitus. We managed to keep blood glucose concentrations within 150-200 mg x dl(-1) with continuous insulin intravenous infusion, and controlled circulation with dopamine. Since the blood glucose on admission was extremely high (1,870 mg x dl(-1)), the severe dehydration due to extreme hyperglycemia might have caused acute renal failure (ARF) and rhabdomyolysis. He was treated with CHDF for them. In a case of fulminant type 1 diabetes mellitus complicated with ARF early intensive support including CHDF for ARF must be considered in addition to intensive insulin therapy.     

Rhabdomyolysis and acute renal failure in children

Acute renal failure (ARF) is an important complication of rhabdomyolysis. However, the contributing factors to the development of ARF in children with rhabdomyolysis remain obscure. The aim of this study was to clarify the factors contributing to the development of ARF in children with rhabdomyolysis. This is a retrospective review of the clinical characteristics, laboratory data, pediatric risk of mortality (PRISM) scores, the occurrence of systemic inflammatory response syndrome (SIRS) criteria, and the number of dysfunctional organs in 18 children with rhabdomyolysis seen in our hospital between 1991 and 2000. The patients were divided into an ARF group (n=9) and a non-ARF group (n=9). All patients with ARF had more than two dysfunctional organs. The incidence of dehydration, serum concentrations of myoglobin, creatinine kinase, aspartate aminotransferase, and lactate dehydrogenase, PRISM scores, and the numbers of SIRS criteria and dysfunctional organs were higher in the ARF group than the non-ARF group. The blood pH and base excess, and urinary pH were lower in the ARF group than in the non-ARF group. These results suggest that ARF is more likely to develop in the presence of dehydration, metabolic acidosis, or severe muscle damage, or with multiple organ failure in children with acute rhabdomyolysis.

Rhabdomyolysis and acute renal failure following arthroscopic knee surgery in a college football player taking creatine supplements

We describe a college football player and weight-lifter who unexpectedly developed rhabdomyolysis and nonoliguric acute renal failure (ARF) following arthroscopic knee surgery. There was swelling and pain without evidence of a compartment syndrome postoperatively. The patient reported that he was an avid weight-lifter and that he was taking up to 10 g/d of a creatine supplement during the 6 weeks prior to this surgery. His ARF resolved over several days, with a peak serum creatinine of 2.3 mg/dl and peak creatine kinase (CK) of 194,000 U/l, following administration of intravenous fluids, mannitol, and sodium bicarbonate. Given the rarity of clinically significant rhabdomyolysis with this type of operation, we suggest that the patient's use of creatine increased the risk of skeletal muscle injury due to ischemia from intra-operative tourniquet application.     

Rhabdomyolysis

Key points Rhabdomyolysis describes the destruction or disintegrationof striated muscle; it is an important cause of acute renalfailure. Creatinine kinase concentration is the most sensitiveand useful indicator of muscle injury in rhabdomyolysis. Themost important intervention is early aggressive crystalloidfluid resuscitation. Life-threatening hyperkalaemia is a commoncause of death and must be treated promptly. Myoglobin-inducedrenal failure has an excellent prognosis.   The term rhabdomyolysis describes the breakdown or disintegrationof striated muscle. Although a broad range of conditions canresult in rhabdomyolysis, the final common pathway of myocytenecrosis involves a rapid increase in intracytoplasmic calcium.This leads to the release of myocyte constituents into the circulation,which can produce life-threatening complications including acutehyperkalaemia and acute renal failure (ARF). Rhabdomyolysis is a common cause of ARF, especially in timesof conflict or after major disasters     

Prognostic value, kinetics and effect of CVVHDF on serum of the myoglobin and creatine kinase in critically ill patients with rhabdomyolysis

BACKGROUND: (I) To investigate the kinetics of the myoglobin and creatine kinase (CK) in rhabdomyolysis. Especially to describe those patients in whom an isolated increase in the myoglobin or the CK occurred at a later stage. (II) To evaluate the sensitivity of the myoglobin and the CK as prognostic tools for the development of Acute renal failure (ARF). (III) To investigate the effect of continuous venovenous haemodiafiltration (CVVHDF) on the myoglobin elimination in ARF. PATIENTS AND METHODS: Prospective and retrospective cohort study carried out in an ICU of a university hospital. A total of 47 critically ill patients with rhabdomyolysis and a plasma myoglobin > 5000 microg l(-1) were admitted between July 1998 and July 2003. RESULTS: (I) The myoglobin peaked 0.66 +/- 0.6 days before the CK. The elimination kinetics of the myoglobin was faster than for the CK. (II) Fifty percent developed ARF. Mortality in the ARF patients was 52% compared to 14% in the non-ARF patients. The sensitivity and specificity of developing ARF were higher with the myoglobin in comparison to the CK. (III) In non-ARF, t(1/2) CK was 25.5 h and t(1/2) myoglobin was 17 h (13-23). In those with ARF treated with CVVHDF, t(1/2) CK was 24.8 and t(1/2) myoglobin was 21 h (17-29). CONCLUSION: (I) The myoglobin peaked earlier than the CK. (II) The myoglobin was a better prognostic tool than the CK. However, the myoglobin also has a wide interindividual range. (III) Though the myoglobin is eliminated in ultrafiltration t(1/2) myoglobin, it was not faster in patients with ARF treated with CVVHDF compared to non-ARF patients.     

Acute renal failure in rhabdomyolysis.

Fifteen to 30% of patients develop acute renal failure (ARF) following rhabdomyolysis and rhabdomyolysis accounts for 5 to 9% of all ARF. Experimental studies revealed two critical factors that predispose to myoglobinuric ARF: hypovolemia/dehydration and aciduria. At the nephron level, three basic mechanisms underlie heme protein toxicity: renal vasoconstriction with decreased renal blood flow, intraluminal cast formation and direct heme protein-induced cytotoxicity. During the early phase of myoglobinuric ARF, hemodynamic process are mainly involved in glomerumar filtration rate decrease while tubular mechanisms occur in the late phase. Critical factors which predispose to myoglobinuric ARF in animal models--i.e. hypovolemia/dehydration and aciduria--are also encountered in human epidemiological studies. Prevention of myoglobinuric ARF rely on rapid and adequate correction of fluid deficits with saline, bicarbonates and mannitol. The choice of hemodialysis technique in the case of constituted ARF strongly depends on the site of intervention, especially in the case of rescue operation. The care of myoglobinuric ARF in intensive care unit do not differ from this of ARF from other causes.     

Acute Renal Failure Due to Rhabdomyolysis in Diabetic Patients

We report a 32-year-old Black man, admitted to the ICU with coma and severe metabolic disturbances due to diabetic ketoacidosis. During the admission, rhabdomyolysis and acute renal failure (ARF) were diagnosed. After metabolic control and gradual decrease of creatine kinase levels, he presented a progressive improvement of renal function. We emphasize nontraumatic rhabdomyolysis as a poorly recognized pathogenetic factor for ARF in diabetic ketoacidosis and suggest that a better understanding of its mechanisms and an early application of protective measures is necessary.

目的:了解过度训练致急性肾损伤(OTIAKI)的发病情况及临床特点。方法:对我院9年间(2001年5月～2010年8月)因5km武装越野跑住院患者的临床病理特点和预后进行分析。结果:83例患者符合入选标准,单纯尿检异常32例,横纹肌溶解症24例,横纹肌溶解伴急性肾衰竭27例。重症OTIAKI的患者除肾脏损害外,还可表现为意识障碍、抽搐、肌痛、棕色尿,血清UREA、CR、CK、CK-MB、LDH、ALT、HBDH等指标明显异常。肾脏病理检查提示为肾小球和肾小管的轻微病变。83例患者死亡1例,病死率为1.2%。结论:过度训练致急性肾损伤已成为近年来急性肾衰竭的重要病因;血清酶升高的幅度越大,病情越重;血清酶水平恢复越慢,预后越差;早期应用肾剂量的多巴胺和山莨菪碱有助于肾功能的恢复,病情严重者及时行血液净化治疗。     

Rhabdomyolysis: clinical analysis of 20 patients

Twenty patients with rhabdomyolysis with and without acute renal failure (ARF) were studied. The patients consisted of 9 males and 11 females with a mean age of 64.5 +/- 3.2 years. Infection, compression and metabolic derangement were implicated as the most common etiologic factors. While 7 patients developed ARF during hospitalization, renal functions were normal in the remaining 13. While the mean ages, serum ARF, significant increases in potassium, phosphate, blood urea nitrogen, creatinine and uric acid were observed. While the mean blood pressure was similar, significant increases in hematocrit and total protein were observed in the patients with ARF. The detailed results indicated that infection, compression and metabolic derangement were the most common etiology factors of rhabdomyolysis, and plasma volume contraction might be responsible for the development of ARF.     

Clinical study of influenza-associated rhabdomyolysis with acute renal failure

AIMS: Influenza-associated rhabdomyolysis induces renal failure with a fatal outcome. The aim of this study is to evaluate the clinical features, diagnosis, and treatment efficacy of influenza-associated rhabdomyolysis patients with acute renal failure (ARF). MATERIALS AND METHODS: The subjects included 6 patients who had presented with rhabdomyolysis and ARF due to influenza infection on admission to our university hospital and its 2 affiliated hospitals between January 2002 and February 2004. We retrospectively examined the cases. RESULTS: All the patients (n = 6) were males, and none of them had received an influenza vaccine. The viruses were identified as influenza A (n = 5) and B (n = 1). Muscular weakness was observed in many cases (n = 5), whereas pain or tenderness was observed in only 1 case (n = 1). For anuric or oliguric patients (n = 4), blood purification therapy was performed, while for patients in whom the urine volume was normal (n = 2), conservative therapy was administered. CONCLUSION: Careful medical attention is necessary when patients have muscle pain and weakness. Early recognition of rhabdomyolysis allows prompt institution of an appropriate therapy that includes blood purification and may minimize the renal dysfunction associated with this disorder.     

Exertion-induced rhabdomyolysis in a patient on statin therapy

Sir, We describe a patient on long-term statin treatment who developedacute renal failure (ARF) from rhabdomyolysis following severeunaccustomed exertion. Reviewing the available literature, wedid not find reports of exertion-induced rhabdomyolysis andARF requiring dialysis while on statins. A 57-year-old male, with hypertension and hyperlipidaemia (on     

Reversible hepatic dysfunction associated with rhabdomyolysis

Hepatic dysfunction was observed in 34 patients with nontraumatic rhabdomyolysis. The serum levels of lactic dehydrogenase were markedly elevated in all patients. The peak values occurred within 72 h of hospitalization. There was no significant difference among patients with (9,044 +/- 1,154 U/l) and without acute renal failure (ARF; 9,125 +/- 3,067 U/l). Similarly, marked elevation in both alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were observed within 72 h after admission to the hospital. They were significantly higher in patients with ARF (ALT: 4,718 +/- 785 vs. 2,496 +/- 927 U/l, p less than 0.01; AST: 3,635 +/- 820 vs. 1,352 +/- 624 U/l, p less than 0.01). Hyperbilirubinemia was noted in 13 of 22 (60%) patients with ARF and in 5 of the 12 (41%) of those without ARF. Serum levels of bilirubin ranged from 2.6 to 14.3 mg/dl. Prothrombin time was prolonged in 4 of 12 (33%) without ARF and in 14 of 22 (63%) of patients with ARF. This abnormality lasted from 1 to 13 days. The magnitude and duration of hyperbilirubinemia and abnormal prothrombin time were similar in patients with and without ARF. Hepatic dysfunction appears to occur in about 25% of patients with rhabdomyolysis. The pathogenesis of these abnormalities is not well defined and may be multifactorial. Hyperpyrexia, hypotension and proteases released from injured muscle may each or all be contributory. These hepatic derangements are reversible.     

Kidney transplantation from donors with rhabdomyolysis and acute renal failure

Rhabdomyolysis in deceased donors usually causes acute renal failure (ARF), which may be considered a contraindication for kidney transplantation. From January 2012 to December 2016, 30 kidneys from 15 deceased donors with severe rhabdomyolysis and ARF were accepted for transplantation at our center. The peak serum creatinine (SCr) kinase, myoglobin, and SCr of the these donors were 15 569±8597 U/L, 37 092±42 100 μg/L, and 422±167 μmol/L, respectively. Two donors received continuous renal replacement therapy due to anuria. Six kidneys exhibited a discolored appearance (from brown to glossy black) due to myoglobin casts. The kidney transplant results from the donors with rhabdomyolysis donors were compared with those of 90 renal grafts from standard criteria donors (SCD). The estimated glomerular filtration rate at 2 years was similar between kidney transplants from donors with rhabdomyolysis and SCD (70.3±14.6 mL/min/1.73 m² vs 72.3±15.1 mL/min/1.73 m²). We conclude that excellent graft function can be achieved from kidneys donors with ARF caused by rhabdomyolysis.     

Acute renal failure due to rhabdomyolysis--clinical investigation on our 6 cases]

Six cases of acute renal failure (ARF) due to rhabdomyolysis were experienced between 1984 and 1989. Patients' ages ranged from 33 to 92 years old (average ages 61) and all were male. The causes of rhabdomyolysis were as follows: one crush syndrome, one acute arterial occlusion, one diabetic hyperosmolar nonketotic coma and three cases of malignant syndrome due to neuroleptica (mainly haloperidol). Underlying diseases included, one case of abdominal aneurysm, two cases of diabetes mellitus, two cases of schizophrenia and one case of reactive psychosis. Dehydration was considered as an important factor in the onset of rhabdomyolysis and ARF, because it was observed in 4 of the cases in this study. In all cases, the serum levels of potassium, phosphorus and uric acid as well as myoglobin and myogenic enzymes increased markedly. In patients with myoglobinuric ARF, severe metabolic acidosis and hypocalcemia in the oliguric phase and hypercalcemia in the diuretic phase were prominent. Muscle biopsy showed myolytic degeneration in 2 of 4 cases. Five cases were treated with hemodialysis and one case was managed conservatively. All 6 cases had relatively good prognosis. However, 3 cases with malignant syndrome showed outcomes more severe than in the other 3 cases without such syndrome.     

Deep vein thrombosis complicating severe hypernatremia,rhabdomyolysis, and acute renal failure in a patient with untreated seizure disorder

We report a 22-year-old male patient with untreated seizure disorder, presenting with increased frequency of seizures followed by encephalopathy. Laboratory evaluation showed severe hypernatremia (175 meq/l sodium), rhabdomyolysis, and acute renal failure (ARF). Excessive insensible water loss in hot and humid weather, associated with an inability to obtain adequate water replacement, led to a hyperosmolar state (plasma osmolality, 398 mOsm/kg). He was vigorously treated with hypotonic fluid supplement and, further, needed dialysis therapy (peritoneal dialysis followed by hemodialysis) for acute renal insufficiency. The patient survived without any neurological sequelae, but the clinical course was complicated by acute deep vein thrombosis. This case represents what we believe is a unique report in the literature of severe hypernatremia developing via the pathogenic mechanism outlined above and the complication of acute peripheral venous thrombosis, which has not been reported in adults. The purpose of this report is to emphasize hyperosmolarity as a newly described cause of rhabdomyolysis, ARF, and a hypercoagulable state.     

横纹肌溶解致急性肾衰竭3例报告及文献复习

目的：探讨横纹肌溶解致急性肾衰竭的发病机制及有效的治疗方法。方法：分析报道典型的横纹肌溶解导致急性肾衰竭3例患者,并作文献复习。结果：患者均为男性,平均年龄33,3岁,2例大量饮酒（其中1例同时注射海洛因）后,另1例由于一氧化碳中毒。有长时间昏睡史,血压偏低。其中有1例患者的肾活检病理报告：急性肾小管坏死,肾小管内存在大量蛋白栓子;免疫组化证实为肌红蛋白。3例患者入院时均无尿,高钾血症,重度酸中毒,所以予以血液透析及对症治疗,痊愈出院。结论：虽然尿中检测到肌红蛋白是诊断横纹肌溶解的“金标准”,但我们认为肾穿刺活检免疫组化证明肾小管内肌红蛋白栓子可作为诊断横纹肌溶解引起急性肾小管坏死更直接证据。酗酒加注射毒品后引起肌溶解急性肾衰竭的病情较重且复杂,早期血液透析治疗可以减少死亡率。     

Relationship between elevated creatine phosphokinase and the clinical spectrum of rhabdomyolysis

The incidence, causes and complications of severe rhabdomyolysis(creatine phosphokinase (CK) 5000 U/l) were studied during a7-year study period in a large university hospital population.This condition was present in 0.074% of all admitted patients.The mortality in the study group (n=93) was 32% and the incidenceof acute renal failure (ARF) 51%. Ischaemia was the most frequentcause, and drugs, alcohol and/or coma were the second most commoncause of severe rhabdomyolysis. Patients with rhabdomyolysisdue to ischaemia were older, had ARF more often, and also hadthe highest mortality. Hyperkalaemia (potassium 5.5 mmol/1)occurred in 13% of the patients, and all of them had or developedan impaired renal function. Hypocalcaemia (calcium 2.00 mmol/1)was found in 41%. The incidence of ARF and electrolyte disturbanceswas higher in patients with CK levels exceeding 15 000 U/l.Mortality was significantly higher in patients with ARF. Plasmaconcentrations of potassium and calcium correlated better withthe severity of renal failure than with the maximal height ofplasma CK.     

Proximal tubular cytochrome c efflux: determinant, and potential marker, of mitochondrial injury

BACKGROUND: Cytochrome c (cyt c) is released from mitochondria after tissue injury, but little is known of its subsequent fate. This study was undertaken to ascertain: (1) does cyt c readily gain access to the extracellular space; (2) if so, what are some determinants of this process; and (3) might cyt c release be a potentially useful marker of in vivo tissue damage. METHODS: Isolated mouse proximal tubules (PT) were subjected to site 1 (rotenone; Rot), site 2 (antimycin A, AA), or site 3 (hypoxic) respiratory chain blockade (+/- 2 mmol/L glycine, to prevent plasma membrane disruption/cell death). Alternatively, oxidant injury was imposed (Fe(2+) or cholesterol oxidase). Extra- and intracellular cyt c levels were quantified by Western blot. Plasma or urine cyt c levels were also determined after rhabdomyolysis or ischemic acute renal failure (ARF) (in mice), or clinical ARF. RESULTS: AA, Rot, and hypoxia caused variable degrees of PT cyt c release (AA > rot approximately hypoxia), but at most, <20% of total cell content was involved. In contrast, Fe(2+) evoked approximately 65% cyt c efflux, and cholesterol oxidation caused approximately 100% cyt c release. Glycine did not block cyt c efflux, dissociating this process from plasma membrane disruption/necrotic cell death. After rhabdomyolysis, plasma cyt c levels rose and correlated with the severity of ARF (r, 0.93 vs. BUNs). Cyt c was detected in urine after both experimental and clinical ARF. CONCLUSION: Cell cyt c release is dependent on the site and the type of mitochondrial injury sustained. Oxidative injury, in general, and cholesterol oxidation, in particular, seem particularly relevant in this regard. After mitochondrial release, cyt c traverses plasma membranes, eventuating in the extracellular space. The data suggest that plasma and/or urine cyt c appearance might function as a clinically useful in vivo marker of mitochondrial stress and the tissue injury sustained.
