To assess the diagnostic value of myoglobin between elective surgery and acute arterial occlusion, serum and urine myoglobin (S-Mb, U-Mb) levels were measured before and for 7 consecutive days following arterial reconstructive surgery in 7 patients with abdominal aortic aneurysm or arteriosclerosis obliterans (elective surgery group), and in 20 patients with acute arterial occlusion due to embolism or thrombosis. They were divided into three groups based on symptoms and other features: mild, moderate, and severe groups. S-Mb and U-Mb levels were normal before surgery with a maximum of 389 ng/ml and 1,670 ng/ml after surgery in the elective surgery group, and 489 ng/ml and 11.7 ng/ml before surgery with a maximum of 703 ng/ml and 294 ng/ml after surgery in the mild cases. These two groups showed no complications after surgery. In the moderate group, high values of 2,420 ng/ml and 25,300 ng/ml were noted before surgery, and these values were elevated to 14,900 ng/ml and 175,000 ng/ml after surgery with complications of acute renal failure or peripheral nerve paresis. In the severe group, the values were 9,440 ng/ml and 260,000 ng/ml before surgery, and 160,000 ng/ml and 1,300,000 ng/ml after surgery, the elevation being associated with the severe clinical complication, myonephropathic metabolic syndrome (MNMS). All patients in this group died of MNMS. S-Mb and U-Mb levels before surgery proved useful for predicting the prognosis of patients with acute arterial occlusion. The findings obtained in our canine studies on the mechanism and treatment of MNMS suggest that alpha-tocopherol, a free radical scavenger, may be effective for treating dreadful complications such as MNMS.

The removal of serum myoglobin with extracorporeal circulation using a column filled with methylmethacrylate-divinylbenzene (MMA-DVB) was studied in experimentally induced myonephropathic metabolic syndrome in the dog. All animals showed marked edema in the hind limbs and degeneration or necrosis of the adductor muscle 5 hours after the reestablishment of arterial flow. The serum levels of myoglobin, creatinine phosphokinase, glutamic oxaloacetic transaminase and aldolase increased linearly after the reperfusion of blood in the group of animals which received no extracorporeal circulation (group 1). Sediments of numerous myoglobin casts in the renal tubules and immunoreactive myoglobin in the renal epithelium of almost all the tubules were seen in 4 out of 5 cases. In the group of animals reperfused with extracorporeal circulation using the MMA-DVB column, serum myoglobin was adsorbed selectively by the column and showed a significantly lower value at 0.5, 1, 2 and 3 hours than that of the group 1 animals. Concomitantly, the immunoreactive myoglobin was absent or scant in the renal epithelium of the proximal convoluted tubule. The present study therefore indicates that extracorporeal circulation using the MMA-DVB column is useful for the removal of serum myoglobin from experimentally induced myonephropathic metabolic syndrome.

In order to prevent myonephropathic metabolic syndrome (MNMS) following acute arterial occlusion of the extremities, the efficacy of plasma filtration to eliminate myoglobin which causes acute renal failure and other metabolites was evaluated by experimental model. Twenty five mongrel dogs weighing 10 to 20 kg were used. Infra-renal aorta and unilateral femoral arteries were ligated and 2/3 of the femoral muscle was carved. After 24 hrs, these ligations were released and thrombectomy was carried out. The dogs were divided into two groups: Group 1 was consisted of the dogs without any treatment and group 2 dogs were treated by plasma filtration. The changes in serum myoglobin, potassium, lactic acid and etc. were compared between the two groups. The plasma filter was hollow-fiber type that was made of polypropylene fiber. The serum level of myoglobin, potassium, CPK, GOT and BUN tended to decrease remarkably after revascularization in group 2 in contrast with those in group 1. There were statistically significant differences between the corresponding data of the two groups. Although the lactic acid levels were lower in group 2 than group 1, those were not significant statistically. In conclusion, the application of plasma filter was effective for the treatment of hyperkalemia and removal of myoglobin and unknown moderate molecular weight pathogenic substances to prevent MNMS.

Some experimental and clinical studies were done from the metabolic viewpoint to elucidate the characteristics of myonephropathic-metabolic syndrome. In experimental dogs with their femoral arteries ligated and two third of femoral muscles divided, aldolase and myoglobin showed remarkable increase without significant changes in electrolytes. Slight increase of GPT and GOT was observed. Amino acids showed elevation in urea, taurin, leucin, isoleucin, valine, threonine, 3-methylhistidine, phenylalanine, histidine, lysine, methionine, tyrosine and anserin and decrease in glutamine, alanine, glycine, proline, carnosine, citrullin and arginine. In patients with acute arterial occlusion, potassium, GOT, LDH, CPK, lactate and pyruvate increased moderately and myoglobin showed remarkable increase and aldolase slight increase. Amino acids showed remarkable increase in 3-methylhistidine and beta-amino-isobutyric acid and moderate increase in phenylalanine and arginine. These results revealed that measurement of free amino acid concentration, especially that of methylhistidine as well as myoglobin, pyruvate, lactate and some other enzymes might be of great help to predict the prognosis of patients with acute arterial occlusion of the extremities.

A 67-year-old man was admitted with traumatic arterial occlusion in his leg 24 h after an accident. A double-lumen catheter was inserted into the left iliac vein, after revascularization, and haemodialysis started using a new membrane dialyser to remove myoglobin effectively. Intramuscular pressure of the limb was measured and, when it was 35 mmHg, staged fasciotomy was performed. A modification of the procedure used to prevent myonephropathic metabolic syndrome and compartment syndrome is described.

Cardiac Troponin is drawing increasing attention from cardiologists, clinicians, researchers, and authorities in Japan, as illustrated by the revision of the PCI reimbursement plan in April 2014 and that of the JCS STEMI Guidelines in December 2013. In the revised PCI reimbursement plan, it is stated that 10,000 points will be added for the performance of PCI when Troponin is positive together with myocardial ischemic observations. In the revised STEMI Guidelines, a description was added stating that high sensitive Troponiri assays are superior to all other cardiac markers, including myoglobin, CK-MB, H-FABP, and conventional Troponin assays. With high sensitive Troponin assays, including hsTnI recently developed by Abbott that can measure 96% of the normal population, increasing numbers of researchers are actively involved in research to elucidate whether high sensitive Troponin assays are useful not only for the diagnosis of ACS (acute coronary syndromes), but also for the prognosis of chronic heart diseases such as heart failure, high blood pressure, diabetes, or metabolic syndrome. In this review, we describe high sensitive Troponin assays from various viewpoints.
