Creatine

This allows for a heavier more intense workout as creatine can fuel muscle development at a greater speed.

Thus, comparison of the infectivity assay and results obtained by the immunofluorescence technique gave somewhat inconsistent results. Sir, Rhabdomyolysis is the most important side effect of statin therapy. In transplant patients it is often caused by an interaction with drugs that inhibit the cytochrome P450 isoenzyme CYP3A4, resulting in elevated serum levels of the statin. However, not all statins are metabolized by this enzyme and they therefore have different drug interaction and safety proles. We describe a case in which failure to appreciate the possibility of a drug interaction between cyclosporin, simvastatin and clarithromycin led to rhabdomyolysis, and discuss whether some statins might be more likely to provoke rhabdomyolysis than others. Case. A 62-year-old woman with chronic glomerulonephritis started dialysis in 1994. During the same year, she underwent coronary artery bypass grafting and was prescribed simvastatin for hypercholesterolaemia. She received a cadaveric renal transplant in 1998 but her graft did not function well and her creatinine was 250 mmolul on discharge. Drug treatment thereafter included prednisolone, azathioprine, cyclosporin and simvastatin 20 mg per day. Renal function remained stable during follow up with cyclosporin levels in the range of 6080 nmolul. In January 1999, she developed a respiratory tract infection with atypical features and was started on clarithromycin 250 mg twice daily for 10 days. At the end of treatment, her serum cyclosporin level had risen to 240 nmolul and serum creatinine to 330 mmolul. This was followed 10 days later by profound muscle weakness and a rise in serum creatine kinase to 7500 IUul. There was no further deterioration in renal function and the patient's symptoms resolved with return of muscle enzymes to normal shortly after stopping simvastatin. Discussion. Rhabdomyolysis is an important but uncommon side effect of statins. Only one case was recorded in the 4S trial and none in WOSCOPS, AFCAPS, LIPID and CARE. With hindsight, the rhabdomyolysis in our patient was a consequence of the co-prescription of three drugs metabolized by the cytochrome P450 enzyme system. Statins have different pharmacokinetic properties. Simvastatin, lovastatin, atorvastatin and cerivastatin are all metabolized by CYP3A4 enzyme and have the potential to interact with CYP3A4 substrates and inhibitors w1x. Co-administration of cyclosporin and clarithromycin, which are CYP3A4 inhibitors, increases statin levels and therefore increases the risk of muscle toxicity Figure 1 ; . Cerivastatin has a dual metabolism with CYP3A4 and CYP2C8 isoenzymes, but elevated serum statin concentrations can still occur in patients co-prescribed itraconazole, erythromycin and cyclosporin w2x. Fluvastatin is presumed.

There was enormous hope followed by crushing disappointment when AZT was introduced as close to a cure in 1986. At that time PWAs were taking two or three times the current dose. And after six months of AZT monotherapy, most people had developed resistance and were essentially taking a toxic placebo. Despite its history, AZT remains an incredibly useful treatment option, with plenty of data to support its use in a wide variety of combinations. Potentially serious side effects include anemia low red blood cells ; , neutropenia low white blood cells ; , and, with long-time use, myopathy inflammation of muscle tissue ; . Stopping the drug at least temporarily ; or reducing your dose may be necessary. Have your CPK creatine phosphokinase ; levels checked regularly to monitor for myopathy. Not enough is known about combining ribavirin Rebetol ; , used to treat hepatitis C, with AZT. Both can cause anemia, and combining the two may cancel out the activity of each. --James Learned.

Levels and local ATP ADP ratios in the cytosol are kept high, thus sustaining membrane ion gradients and other vital energy-consuming processes at a highly efficient level, and 2 ; mitochondria are protected from MPT pore opening via functional coupling of the mtCK reaction to oxidative phosphorylation. Taken together, our findings offer important clues on MPT regulation by mitochondrial ADP phosphorylation and may have interesting implications for the design of creatine analogs to treat patients with neurodegenerative diseases. In order to fully exploit the advantages of the PCr shuttle for cell survival, such analogs would have to be substrates for CK in both the forward and reverse direction of the reaction. Table B1.

And 23.3 in 6 hours, and in a second experiment 30.5 in 3 hours and 22.3 in 6 hours. The relative increases over the control values in the liver with glycocyamine were of the same order of magnitude as those found in kidney. The increases in true creatine in the liver were probably relatively much larger, since most of the chromogenic material in the liver with the Jaffe reagent is not creatine Table I, and also Baker and Miller ; . There is another physiological factor which must be taken into account in interpreting the data obtained by Bodansky. This factor is that the kidney is better able to store creatine than the liver. The analyses of Baker and Miller and our own show that the true creatine content of the kidney is 4 or times that of the liver. Bodansky found that when creatine was fed the creatine content of the liver was twice the control value at the 3rd hour but had declined to the control value by the 6th hour, whereas in the kidney the concentration was 70 per cent above the control value at the end of the 6th hour. Our observations show conclusively that glycocyamine can be methylated by rat liver. The rate of methylation by kidney slices is much slower than in liver, if it is not absolutely negative. All these observations are brought into accord by the hypothesis that in the experiments of Bodansky the creatine synthesized from glycocyamine in liver was quickly removed by the blood and stored for a relatively fang period in the kidney. We have no reliable data of our own at present on the possible conversion of glycocyamine to creatine in other organs or in the muscles. Fisher and Wilhelmi found that when isolated male rabbit heart was perfused there was an increase in creatine when arginine was added to the perfusate. No increase in creatine was observed under these conditions in the hearts of prepubertal animals. Davenport, Fisher, and Wilhelmi 12 ; , extending these observations, found that glycolic acid was essential for the methylation of glycocyamine. They suggested the following mechanism of creatine formation in the rabbit heart. Arginine is broken down to glycocyamine and glycolic acid; the glycolic acid then methylates the glycocyamine to form creatine. In rat and rabbit liver slices the results with arginine, with and without glycolic acid or glycine, and with the two acids alone did.

And without heart disease, 1-5 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors statins ; reduce cardiovascular morbidity and mortality. Ongoing research6-9 is investigating the possible role of statins in the treatment of dementia, hypertension, diabetes mellitus, and arthritis. Because of the cardiovascular benefits and improved survival among patients receiving statins, these medications are now the most prescribed class of drugs in the United States.10 Statin use is expected to increase with the advancing age of society and as additional benefits of statins are clarified.11 These 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors may cause myotoxic effects, with muscle pain occurring in 2% to 11% of patients, and clinically significant myopathy, defined as a creatine kinase CK ; level more than 10 times the reference value, with associated muscle symptoms occurring in approximately 0.5% of patients.12-15 The Heart Protection Study3 identified no significant difference in the in!
