Amylase creatinine clearance ratio after biliary surgery.
The amylase creatinine clearance ratio (ACCR) is considered to be a more sensitive index of acute pancreatitis than the serum amylase level. Serial ACCR estimations were undertaken in 25 patients undergoing an elective cholecystectomy. Using accepted criteria, 28% of these patients developed, in the postoperative period, biochemical evidence of pancreatic gland damage, although the serum amylas...
متن کاملRenal clearance of pancreatic and salivary amylase relative to creatinine clearance in patients with renal disease and proteinuria.
To study the charge-selective properties of the glomerular filter in renal disease, we measured the fractional clearance, relative to creatinine clearance (ECC), of the amylase isoenzymes pancreatic amylase and salivary amylase, which have identical size but different charge. In 63 healthy subjects the mean (and SD) fractional excretion of pancreatic amylase, 4.07% (1.24%), was fourfold that of...
متن کاملRenal clearance of pancreatic and salivary amylase relative to creatinine in patients with chronic renal insufficiency.
Pancreatic and salivary amylase/creatinine clearance ratios in patients with various degrees of renal impairment were compared with those obtained for control subjects. In chronic renal insufficiency (mean GFR 30 ml/min +/- 15 SD; n = 13) the clearance ratios for pancreatic (mean 3.5 +/- 1.85 SD) and salivary (mean 2.3 +/- 1.3 SD) amylase were significantly higher (P less than 0.05) than those ...
متن کاملPancreatic and salivary amylase/creatinine clearance ratios in normal subjects and in patients with chronic pancreatitis.
The clearance of pancreatic and salivary amylase relative to creatinine was measured in 26 control subjects and 22 patients with chronic pancreatitis. Control values for pancreatic amylase clearance (+/- SD) were 2.64 +/- 0.86% compared with 1.54 +/- 0.95% for salivary amylase. In chronic pancreatitis, pancreatic amylase clearance ratios were significantly higher than controls (P less than 0.00...
متن کاملEstimation of Creatinine Clearance in Patients with Unstable Renal Function
Measurement of creatinine clearance (CCr) has long been a problem in sick patients, largely because of the need to collect a carefully timed urine specimen to determine it. However, a number of years ago, several methods were developed to estimate CCr without a urine specimen [1-4]. However, all these approaches only considered the situation where serum creatinine was stable. Because of this, a...
