Background and aims Serum amylase is a traditional measure used to establish the diagnosis of acute pancreatitis (AP). The current study aimed to assess the predictors and clinical outcome of AP with low serum amylase. Methods All patients were divided into two groups, based on their serum amylase level within the first 2 days after hospital admission: group 1 (amylase ≥300 U/L) and group 2 (...

The mean amylase level in 42 human bile samples was 154 IU/l and there was no significant difference in the amylase activity of 32 paired serum and bile samples. Estimation of the amylase thermolability of bile showed it to be similar to that of serum. This suggests that the amylase activity in bile may have filtered through the liver from the hepatic circulation rather than refluxed from the p...

introduction and aims: noscapine has been recently known as an antagonist of bradykinin, and in this study its effect on the animal model of acute pancreatitis has been evaluated. materials and methods: 49 male wistar rats have been evaluated in five experimental and four control groups. common bile duct has been ligated by means of surgery to induce acute pancreatitis in rats. the resulted inf...

Little is known about the associations of eating a late-evening meal (ELM), a putative unhealthy eating behavior, with low serum amylase, other eating behaviors, and cardiometabolic risk factors. Therefore, we investigated whether ELM before bedtime was associated with low serum amylase or other clinical factors in 2,426 asymptomatic adults aged 20-80 years. Multivariate logistic regression ana...

Protein activation of urinary alpha-amylase (EC 3.2.1.1) activity was observed during an evaluation of the Du Pont aca procedure for the determination of urinary alpha-amylase. This activation effect became constant for urinary albumin concentrations exceeding 1.50 g/liter. It is recommended that urinary alpha-amylase be analyzed with sufficient albumin added to maximize this effect. The aca al...

We describe a new method for measuring pancreatic and salivary-type amylases in serum that requires no electrophoresis or chromatography. An inhibitor protein (from wheat) with a 100-fold greater specificity for human salivary than for human pancreatic amylase was used to analyze mixtures of the two enzymes. The concentration of pancreatic and salivary amyalase was determined in 141 normal sera...

Background/Aims This study aimed to evaluate the diagnostic role of low serum amylase and lipase values in the detection of chronic pancreatitis. Methods Patients underwent endoscopic retrograde cholangiopancreatography and were diagnosed with non-calcific chronic pancreatitis (NCCP; n=99) and calcific chronic pancreatitis (CCP; n=112). Patient serum amylase and lipase values were compared wi...

Hyperamylasemia is the most common biochemical marker for the diagnosis of acute pancreatitis, but has low specificity. A 9-year-old girl presented to our hospital with complaints of pain abdomen, fever and vomiting for a week. Her serum amylase done elsewhere was 3500 U/ L, and with suspicion for acute pancreatitis, she was referred to our center. On examination, her abdomen was soft with mild...

Background. Serum lipase and amylase are biochemical analyses used to establish the diagnosis of acute pancreatitis (AP). Despite lipase having been shown internationally to be a more sensitive and specific test, amylase remains a popular first-line test.Objective. To provide a local basis for the recommendation of the best first-line laboratory test, an assessment of their performance in our l...
