Late referral of end-stage renal failure. (1/7078)

We studied all new patients accepted for renal replacement therapy (RRT) in one unit from 1/1/96 to 31/12/97 (n = 198), to establish time from nephrology referral to RRT, evidence of renal disease prior to referral and the adequacy of renal management prior to referral. Sixty four (32.3%, late referral group) required RRT within 12 weeks of referral. Fifty-nine (29.8%) had recognizable signs of chronic renal failure > 26 weeks prior to referral. Patients starting RRT soon after referral were hospitalized for significantly longer on starting RRT (RRT within 12 weeks of referral, median hospitalization 25.0 days (n = 64); RRT > 12 weeks after referral, median 9.7 days (n = 126), (p < 0.001)). Observed survival at 1 year was 68.3% overall, with 1-year survival of the late referral and early referral groups being 60.5% and 72.5%, respectively (p = NS). Hypertension was found in 159 patients (80.3%): 46 (28.9%) were started on antihypertensive medication following referral, while a further 28 (17.6%) were started on additional antihypertensives. Of the diabetic population (n = 78), only 26 (33.3%) were on an angiotensin-converting-enzyme inhibitor (ACEI) at referral. Many patients are referred late for dialysis despite early signs of renal failure, and the pre-referral management of many of the patients, as evidenced by the treatment of hypertension and use of ACEI in diabetics, is less than optimal.

Mycophenolate mofetil prevents the progressive renal failure induced by 5/6 renal ablation in rats. (2/7078)

BACKGROUND: Extensive renal ablation is associated with progressive sclerosis of the remnant kidney. Because lymphocytes and monocytes accumulate in the remnant kidney, it is likely that they play a role in the renal scarring. Therefore, we treated rats with 5/6 nephrectomy (5/6Nx) with mycophenolate mofetil (MMF), a drug that has an antiproliferative effect and that suppresses the expression of intercellular adhesion molecules. METHODS: Sprague-Dawley rats with 5/6Nx received MMF (30 mg. kg-1. day-1 by daily gastric gavage, N = 15) or vehicle (N = 16). Ten additional rats were sham operated. All rats were fed a 30% protein diet. Body weight, serum creatinine, and urinary protein excretion were determined weekly. Lipid peroxidation, as a measure of oxidative stress observed by urinary malondialdehyde determinations, was performed every two weeks. Histologic studies were done in the remnant kidney four weeks (9 rats from the vehicle-treated group, 7 rats from the MMF group, and 5 sham-operated rats) and eight weeks after surgery (the remaining rats). Glomerular volume, sclerosis in glomeruli (segmental and global) and interstitium (semiquantitative scale), infiltrating lymphocytes and macrophages (CD43- and ED1-positive cells), and expression of adhesion molecules (CD54, CD18, and CD11b) were analyzed. RESULTS: MMF treatment prevented the progressive increment in serum creatinine and the proteinuria observed in the 5/6 nephrectomized rats during the eight weeks of observation (P < 0.01). Weight gain was comparable in the MMF-treated and sham-operated rats, whereas weight gain was decreased in untreated 5/6 nephrectomized rats. Excretion of malondialdehyde increased after surgery but returned sooner to control levels in the MMF-treated rats. Increments in glomerular size and mean arterial blood pressure induced by renal ablation were not modified by MMF treatment. Eight weeks after surgery, segmental sclerosis was present in 48.4 +/- 8.35% (+/- sd) glomeruli in the vehicle-treated group versus 25 +/- 10.5% in the MMF-treated group (P < 0.001). Interstitial fibrosis was reduced significantly with MMF treatment (P < 0.001). Infiltration with CD43- and ED1-positive cells in glomeruli and interstitium was two to five times lower in MMF-treated rats (P < 0.01). Expression of adhesion molecules CD18 and CD11b was similarly reduced. CONCLUSION: MMF ameliorates the progressive renal damage in the remnant kidney after 5/6Nx. This effect is associated with a reduction in the infiltration of lymphocytes and monocytes, whereas glomerular hypertrophy and systemic hypertension are unchanged. (+info)

Serum levels of 1,25-dihydroxyvitamin D, 24,25-dihydroxyvitamin D, and 25-hydroxyvitamin D in nondialyzed patients with chronic renal failure. (3/7078)

BACKGROUND: In patients with chronic renal failure (CRF), abnormalities in vitamin D metabolism are known to be present, and several factors could contribute to the abnormalities. METHODS: We measured serum levels of three vitamin D metabolites, 1,25(OH)2D, 24, 25(OH)2D and 25(OH)D, and analyzed factors affecting their levels in 76 nondialyzed patients with CRF (serum creatinine> 1.6 and < 9.0 mg/dl), 37 of whom had diabetes mellitus (DM-CRF) and 39 of whom were nondiabetic (nonDM-CRF). RESULTS: Serum levels of 1,25(OH)2D were positively correlated with estimated creatinine clearance (CCr; r = 0.429; P < 0.0001), and levels of 24,25(OH)2D were weakly correlated with CCr (r = 0.252, P < 0.05); no correlation was noted for 25(OH)D. Serum levels of all three vitamin D metabolites were significantly and positively correlated with serum albumin. Although there were no significant differences in age, sex, estimated CCr, calcium and phosphate between DM-CRF and nonDM-CRF, all three vitamin D metabolites were significantly lower in DM-CRF than in nonDM-CRF. To analyze factors influencing vitamin D metabolite levels, we performed multiple regression analyses. Serum 25(OH)D levels were significantly and independently associated with serum albumin, presence of DM and serum phosphate (R2 = 0.599; P < 0.0001). 24,25(OH)2D levels were significantly and strongly associated with 25(OH)D (beta = 0.772; R2 = 0.446; P < 0.0001). Serum 1,25(OH)2D levels were significantly associated only with estimated CCr (R2 = 0. 409; P < 0.0001). CONCLUSIONS: These results suggest that hypoalbuminemia and the presence of DM independently affect serum 25(OH)D levels, probably via diabetic nephropathy and poor nutritional status associated with diabetes, and that 25(OH)D is actively catalyzed to 24,25(OH)2D in CRF, probably largely via extrarenal 24-hydroxylase. Serum levels of 1,25(OH)2D were significantly affected by the degree of renal failure. Thus, this study indicates that patients with CRF, particularly those with DM, should receive supplements containing the active form of vitamin D prior to dialysis. (+info)

Plasma total homocysteine and cysteine in relation to glomerular filtration rate in diabetes mellitus. (4/7078)

BACKGROUND: The plasma concentrations of total homocysteine (tHcy) and total cysteine (tCys) are determined by intracellular metabolism and by renal plasma clearance, and we hypothesized that glomerular filtration is a major determinant of plasma tHcy and tCys. We studied the relationships between the glomerular filtration rate (GFR) and plasma tHcy and tCys in populations of diabetic patients with particularly wide ranges of GFR. METHODS: We measured GFR, urine albumin excretion rate (UAER), plasma tHcy, tCys, methionine, vitamin B12, folate, C-peptide, and routine parameters in 50 insulin-dependent diabetes mellitus (IDDM) and 30 non-insulin-dependent diabetes mellitus (NIDDM) patients. All patients underwent intensive insulin treatment and had a serum creatinine concentration below 115 micromol/liter. RESULTS: Mean plasma tHcy in diabetic patients (0.1 micromol/liter) was lower than in normal persons (11.1 micromol/liter, P = 0.0014). Mean plasma tCys in diabetic patients (266.1 micromol/liter) was also lower than in normal persons (281.9 micromol/liter, P = 0.0005). Seventy-three percent of the diabetic patients had relative hyperfiltration. Plasma tHcy and tCys were closely and independently associated with GFR, serum folate, and serum B12. However, plasma tHcy was not independently associated with any of the 22 other variables tested, including age, serum creatinine concentration, UAER, total daily insulin dose, and glycemic control. CONCLUSIONS: Glomerular filtration rate is an independent determinant of plasma tHcy and tCys concentrations, and GFR is rate limiting for renal clearance of both homocysteine and cysteine in diabetic patients without overt nephropathy. Declining GFR explains the age-related increase in plasma tHcy, and hyperfiltration explains the lower than normal mean plasma tHcy and tCys concentrations in populations of diabetic patients.

HIV-associated nephropathy is a late, not early, manifestation of HIV-1 infection. (5/7078)

BACKGROUND: Human immunodeficiency virus-associated nephropathy (HIVAN) can be the initial presentation of HIV-1 infection. As a result, many have assumed that HIVAN can occur at any point in the infection. This issue has important implications for appropriate therapy and, perhaps, for pathogenesis. Since the development of new case definitions for acquired immunodeficiency syndrome (AIDS) and better tools to assess infection, the relationship of HIVAN to the time of AIDS infection has not been addressed. In this study, we reassessed the stage of infection at the time of HIVAN diagnosis in 10 patients, and we reviewed all previously published cases applying the new case definitions to assess stage of infection. METHODS: HIVAN was confirmed by kidney biopsy in HIV seropositive patients with azotemia and/or proteinuria. CD4+ cell count and plasma HIV-1 RNA copy number were measured. We also reviewed all published cases of HIVAN to determine if AIDS-defining conditions, by current Centers for Disease Control definitions, were present in patients with biopsy-proven HIVAN. RESULTS: Twenty HIV-1 seropositive patients with proteinuria and an elevated creatinine concentration were biopsied. HIVAN was the single most common cause of renal disease. CD4+ cell count was below 200/mm3 in all patients with HIVAN, fulfilling Centers for Disease Control criteria for an AIDS-defining condition. HIV-1 plasma RNA was detectable in all patients with HIVAN. In reviewing previous reports, an AIDS-defining condition was present in virtually all patients with HIVAN. CONCLUSION: HIVAN develops late, not early, in the course of HIV-1 infection following the development of AIDS. This likely accounts for the poor prognosis noted in previous publications and has implications for pathogenesis. In addition, given the detectable viral RNA levels, highly active antiretroviral therapy is indicated in HIVAN. Highly active antiretroviral therapy may improve survival as well as alter the natural history of HIVAN. (+info)

Long-term effects of cyclosporine A in Alport's syndrome. (6/7078)

BACKGROUND: In 1991, our initial results of cyclosporine A (CsA) administration in eight patients with Alport's syndrome were published. A significant decrease in or disappearance of proteinuria and apparently good tolerance to CsA were observed in all patients. METHODS: CsA administration has been maintained in these eight patients with the aim of obtaining further information about the clinical course of the disease. The ages of these eight patients currently range from 15 to 27 years, and the mean duration of treatment is from 7 to 10 years (x = 8.4 years). RESULTS: Renal function has remained stable, with no evaluable changes in serum creatinine levels compared with pre-CsA treatment values. Proteinuria in all patients has either remained negative or are values far lower than pretreatment levels. A second renal biopsy was performed in all patients after five years of CsA administration. No aggravation of the lesion present at the first biopsy or lesions typical of cyclosporine intoxication was observed. CONCLUSIONS: After a mean duration of 8.4 years and with no deterioration in renal function, we found possible beneficial effects of the continued treatment of CsA in patients with Alport's syndrome who present evidence of progression to renal insufficiency.

Renal failure predisposes patients to adverse outcome after coronary artery bypass surgery. VA Cooperative Study #5. (7/7078)

BACKGROUND: More than 600,000 coronary artery bypass graft (CABG) procedures are done annually in the United States. Some data indicate that 10 to 20% of patients who are undergoing a CABG procedure have a serum creatinine of more than 1.5 mg/dl. There are few data on the impact of a mild increase in serum creatinine concentration on CABG outcome. METHODS: We analyzed a Veterans Affairs database obtained prospectively from 1992 through 1996 at 14 of 43 centers performing heart surgery. We compared the outcome after CABG in patients with a baseline serum creatinine of less than 1.5 mg/dl (median 1.1 mg/dl, N = 3271) to patients with a baseline serum creatinine of 1.5 to 3.0 mg/dl (median 1.7, N = 631). RESULTS: Univariate analysis revealed that patients with a serum creatinine of 1.5 to 3.0 mg/dl had a higher 30-day mortality (7% vs. 3%, P < 0.001) requirement for prolonged mechanical ventilation (15% vs. 8%, P = 0.001), stroke (7% vs. 2%, P < 0.001), renal failure requiring dialysis at discharge (3% vs. 1%, P < 0.001), and bleeding complications (8% vs. 3%, P < 0.001) than patients with a baseline serum creatinine of less than 1.5 mg/dl. Multiple logistic regression analyses found that patients with a baseline serum creatinine of less than 1.5 mg/dl had significantly lower (P < 0.02) 30-day mortality and postoperative bleeding and ventilatory complications than patients with a serum creatinine of 1.5 to 3.0 mg/dl when controlling for all other variables. CONCLUSION: These results demonstrate that mild renal failure is an independent risk factor for adverse outcome after CABG. (+info)

Effect of fasting on temporal variation in the nephrotoxicity of amphotericin B in rats. (8/7078)

Evidence for temporal variation in the nephrotoxicity of amphotericin B was recently reported in experimental animals. The role of food in these variations was determined by studying the effect of a short fasting period on the temporal variation in the renal toxicity of amphotericin B. Twenty-eight normally fed and 28 fasted female Sprague-Dawley rats were used. Food was available ad libitum to the fed rats, while the fasted animals were fasted 12 h before and 24 h after amphotericin B injection to minimize stress for the animals. Water was available ad libitum to both groups of rats, which were maintained on a 14-h light, 10-h dark regimen (light on at 0600 h). Renal toxicity was determined by comparing the levels of excretion of renal enzyme and the serum creatinine and blood urea nitrogen (BUN) levels at the time of the maximal (0700 h) or the minimal (1900 h) nephrotoxicity after the intraperitoneal administration of a single dose of dextrose (5%; control group) or amphotericin B (50 mg/kg of body weight; treated group) to the rats. The nephrotoxicities obtained after amphotericin B administration at both times of day were compared to the nephrotoxicities observed for time-matched controls. In fed animals, the 24-h urinary excretion of N-acetyl-beta-D-glucosaminidase and beta-galactosidase was significantly higher when amphotericin B was injected at 0700 and 1900 h. The excretion of these two enzymes was reduced significantly (P < 0.05) in fasting rats, and this effect was larger at 0700 h (P < 0.05) than at 1900 h. The serum creatinine level was also significantly higher (P < 0.05) in fed animals treated at 0700 h than in fed animals treated at 1900 h. Fasting reduced significantly (P < 0.05) the increase in the serum creatinine level, and this effect was larger in the animals treated at 0700 h. Similar data were obtained for BUN levels. Amphotericin B accumulation was significantly higher (P < 0.05) in the renal cortexes of fed rats than in those of fasted animals, but there was no difference according to the time of injection. These results demonstrated that fasting reduces the nephrotoxicity of amphotericin B and that food availability is of crucial importance in the temporal variation in the renal toxicity of amphotericin B in rats.

In medicine , the BUN-to-creatinine ratio is the ratio of two serum laboratory values, the blood urea nitrogen (BUN) (mg/dL) and serum creatinine (Cr) (mg/dL). (wikipedia.org)
In Canada and Europe the units are also different (mmol/L). The units of creatinine are also different (μmol/L), and this value is termed the urea-to-creatinine ratio . (wikipedia.org)
The BUN-to-creatinine ratio generally provides more precise information about kidney function and its possible underlying cause compared with creatinine level alone. (medicinenet.com)
Examples of this are when creatinine is measured with protein to calculate a urine protein/creatinine ratio (UP/CR) and when it is measured with microalbumin to calculate microalbumin/creatinine ratio (also known as albumin/creatinine ratio, ACR). (labtestsonline.org.uk)
Note: See Analytical Note on comparing the urine albumin-creatinine ratio of the random urine (first collection) and the follow-up first-morning void urine (second collection). (cdc.gov)
Urine albumin-creatinine ratio is used to classify stages of chronic kidney disease. (cdc.gov)
Therefore, measurement of urinary albumin and creatinine concentrations are performed and an albumin:creatinine ratio (ACR) was determined from both a random urine and a first morning void. (cdc.gov)
The ratio of urine albumin to urine creatinine is used to predict nephropathy risk in diabetic patients. (cdc.gov)
Your healthcare provider may also order a protein-to-creatinine ratio test done on your urine. (rochester.edu)
The levels of blood creatinine and blood urea nitrogen (BUN) can be used to find the BUN-to-creatinine ratio. (cigna.com)
This ratio can help your doctor check for problems, such as dehydration, that may cause abnormal BUN and creatinine levels. (cigna.com)
This causes a high BUN-to-creatinine ratio. (cigna.com)
Most of the time, tests for albumin and creatinine are done on a urine sample collected randomly (not timed) and an albumin-to-creatinine ratio (ACR) is calculated. (labtestsonline.org)
A urine albumin test and albumin to creatinine ratio (ACR) are used to screen for kidney disease in people with chronic conditions, such as diabetes and high blood pressure (hypertension). (labcorp.com)
Instead of just testing serum creatinine, the more accurate test of kidney function is to test the ratio of creatinine in your urine vs your serum. (startingstrength.com)
request that they test serum/urine creatinine ratio rather than rely on the serum creatinine alone. (startingstrength.com)
A higher than normal creatinine and blood urea nitrogen ( BUN ) may be indicative of dehydration when BUN-to-creatinine ratio is abnormal, with BUN levels rising higher than creatinine levels. (statemaster.com)
In the case of dehydration, the ratio of urea to creatinine will give the doctor a good deal of information as to what might be happening. (healthandnutritiontips.net)

As of March 2007, we have recruited 50 subjects, and continue to study the predictive value of spot urine chloride/creatinine ratio, as described. (clinicaltrials.gov)
Whereas measurement of albumin:creatinine ratio (ACR) in spot urine samples is indicated for determining microalbuminuria, its performance or that of urinary albumin excretion rate (UAER) in predicting microalbuminuria in sickle cell disease (SCD) is unclear. (uwi.edu)
In this study of 1,588 patients who underwent CRRT in a single tertiary center intensive care unit, the 30- and 90-day mortality risks were significantly lower in patients with higher creatinine:cystatin C ratio at the time CRRT was begun. (sciencecodex.com)
These findings suggest that creatinine:cystatin C ratio may be a simple, useful tool for mortality risk assessment in critically ill patients who develop AKI. (sciencecodex.com)
Creatinine increases of 30% or more were associated with an increased adjusted incidence rate ratio for all outcomes, compared with increases of less than 30%: 3.43 (95% confidence interval 2.40 to 4.91) for end stage renal disease, 1.46 (1.16 to 1.84) for myocardial infarction, 1.37 (1.14 to 1.65) for heart failure, and 1.84 (1.65 to 2.05) for death. (bmj.com)
The Protein and Creatinine urine test will measure the levels of protein, creatinine and protein:creatinine ratio to assess for chronic kidney disease. (healthtestingcenters.com)
A team, led by Keiichi Sumida, MD, MPH, PhD, Division of Nephrology, Department of Medicine, University of Tennessee Health Science Center, developed equations for converting urine protein-creatinine ratio (PCR) and dipstick protein to urine albumin-creatinine ratio (ACR) and tested their diagnostic accuracy in chronic kidney disease screening and staging.

The study, " Conversion of Urine Protein-Creatinine Ratio or Urine Dipstick Protein to Urine Albumin-Creatinine Ratio for Use in Chronic Kidney Disease Screening and Prognosis ," was published online in the Annals of Internal Medicine . (hcplive.com)

Therefore, creatinine levels in blood and urine may be used to calculate the creatinine clearance (CrCl), which reflects the glomerular filtration rate (GFR). (princeton.edu)
By comparing the creatinine level in urine with the creatinine level in blood , the creatinine clearance test estimates the glomerular filtration rate (GFR) . (medlineplus.gov)
Linearity comparisons were made between predictors of renal functioning (serum urea nitrogen (SUN) level, creatinine level, Modification of Diet in Renal Disease (MDRD) rate, and Mayo estimated glomerular filtration rate (eGFR) and one-year mortality risk, risk magnitude, and relative importance of predictors. (rwjf.org)
Knowing your serum creatinine allows your doctor to calculate your creatinine level along with your age, gender and race, to determine your glomerular filtration rate (GFR). (davita.com)
is designed to explore issues related to key biomarkers for diabetic kidney disease (creatinine, glomerular filtration rate [eGFR], cystatin C, and urine albumin) in the context of physiologic and laboratory limitations that may influence interpretation of the results. (aacc.org)
The creatinine clearance test is used to estimate Glomerular Filtration Rate (GFR) . (myhealth.gov.my)
Less dramatic consequences created by concern for contrast-induced nephropathy (CIN) were the adoption of "preventive" measures, such as formal patient questionnaires and measurements of precontrast serum creatinine level or estimated glomerular filtration rate. (thefreedictionary.com)
A blood creatinine level is also used to estimate the glomerular filtration rate (GFR) which is a measure of the kidney filtration function. (ndtv.com)

A urine creatinine test measures the amount of creatinine in the urine. (kidshealth.org)
It is for this reason that standard blood tests routinely check the amount of creatinine in the blood. (medicinenet.com)
This test measures the amount of creatinine in your blood and/or urine. (labtestsonline.org.uk)
Since it is produced and removed at a relatively constant rate, the amount of creatinine in urine can be compared to the amount of another substance being measured. (labtestsonline.org.uk)
The amount of creatinine in the blood depends partly on the amount of muscle tissue you have. (cigna.com)
Any one person will produce the same amount of creatinine each day. (kidney.org.uk)

Normal levels of creatinine in the blood vary from gender and age of the individual. (medhelp.org)
So as the function of the kidney improves the level of creatinine will get back to normal in the blood. (medhelp.org)
According to the Family Practice Notebook, normal creatinine values for adult males are between 0.8 and 1.3 mg/dl. (livestrong.com)
If serum creatinine levels are not normal, it is important to get the test repeated before panicking. (livestrong.com)
Creatinine is a normal metabolic by-product of muscle tissue function. (livestrong.com)
A normal creatinine level, according to MayoClinic.com, falls somewhere between 0.6 to 1.2 mg per dL. (livestrong.com)
Maintaining normal levels of creatinine and BUN may involve taking medications or altering your diet. (livestrong.com)
Those with one kidney will have higher than "normal" levels of creatinine circulating in their blood (roughly 1.8 mg/dl or 160 umol/L). (healingwell.com)
Most men with normal kidney function have approximately 0.6 to 1.2 milligrams/deciliters (mg/dL) of creatinine. (davita.com)
Most women with normal kidney function have between 0.5 to 1.1 mg/dL of creatinine. (davita.com)
If you are muscular, your urine creatinine level may be higher than normal. (rochester.edu)
If you are of small stature or have little muscle mass because of disease, your urine creatinine level will likely be lower than normal. (rochester.edu)
Creatinine measurements are useful in the monitoring of disease progression, with the diagnosis of renal failure when SCr levels are greater than the upper normal interval 4 . (randox.com)
Is my serum creatinine level normal? (ndtv.com)
Home » Frequently asked Questions on Health » Is my serum creatinine level normal? (ndtv.com)
A normal level of creatinine depends on how much muscle mass you have. (vidanthealth.com)
Can you tell me if had any history of kidney disease or medical problems because a creatinine of 2 mg/dl is not normal to begin with. (ukidney.com)
Conclusion: Prospectively measured serum creatinine, within normal ranges, is positively related to prostate cancer risk. (aacrjournals.org)

Main outcome measures Poisson regression was used to compare rates of end stage renal disease, myocardial infarction, heart failure, and death among patients with creatinine increases of 30% or more after starting treatment against those without such increases, and for each 10% increase in creatinine. (bmj.com)

The rate difference between the two wavelengths is proportional to the concentration of creatinine in the reaction cup. (cdc.gov)

If kidney function is abnormal, creatinine level increases in the blood because less creatinine is excreted through the urine. (medlineplus.gov)
When your blood creatinine level increases, you may notice many complications. (selfgrowth.com)
Even small increases in serum creatinine levels during hospitalization raise the risk of end stage renal disease and mortality of elderly patients over the long term, according to a University of Alabama at Birmingham (UAB) study in the March issue of the Archives of Internal Medicine. (innovations-report.com)
With these findings, the study calls for clinicians to closely monitor and aggressively treat patients experiencing increases in creatinine levels. (innovations-report.com)
Results Among the 2078 (1.7%) patients with creatinine increases of 30% or more, a higher proportion were female, were elderly, had cardiorenal comorbidity, and used non-steroidal anti-inflammatory drugs, loop diuretics, or potassium sparing diuretics. (bmj.com)
Conclusions Increases in creatinine after the start of angiotensin converting enzyme inhibitor/angiotensin receptor blocker treatment were associated with adverse cardiorenal outcomes in a graduated relation, even below the guideline recommended threshold of a 30% increase for stopping treatment. (bmj.com)

Some drugs may increase your creatinine levels without causing kidney damage and interfere with your test results. (healthline.com)
Diabetics often develop kidney damage and may develop increased creatinine levels. (wisegeek.com)
Elevated creatinine level reflects underlying kidney damage/injury, described as acute if it happened over period of few days to weeks as might be in the above case following the episode of malaria, or chronic if it remains elevated for more than 3 months. (ndtv.com)

Background: Several studies have examined serum creatinine as a marker for prostate cancer stage, recurrence, and prognosis. (aacrjournals.org)

Older people will generally have lower levels of creatinine in their blood, while heavily muscled younger people generally have slightly higher than average creatinine levels. (healthandnutritiontips.net)

Creatinine is a chemical waste molecule that is generated from muscle metabolism. (medicinenet.com)
Creatinine, a byproduct of muscle metabolism, is normally released into the urine at a constant rate and its level in the urine is an indication of the urine concentration. (labtestsonline.org)
Creatinine is a break down product of muscle metabolism and is measured in the blood. (kidney.org)
Serum creatinine could be a marker for homocysteine status and one-carbon metabolism, as synthesis of the former results in removal of a methyl group from S -adenosylmethionine, creation of homocysteine, and potentially reducing availability of one-carbon groups for DNA methylation, synthesis, and repair ( 9 , 10 ). (aacrjournals.org)

Urinary albumin and creatinine are measured. (cdc.gov)
